Examples of forward-looking statements include those related to our future financial and operating results, including our 2019 financial guidance and goals, operating expenses and gross margins, commercial development efforts, future growth and growth strategy, future product sales, product launches, ongoing and future clinical trials, ongoing and future product development and our regulatory activities as well as the timing of these events and activities.
These forward-looking statements involve risk and uncertainty that could cause actual events, performance and results to differ materially. They are identified and described in today's press release and under Risk Factors in our Form 10-K for the year ended December 31, 2018, and our Form 10-Q for the quarter ended September 30, 2019, which we will file shortly.
We undertake no duty or obligation to update our forward-looking statements. On today's call, we'll begin with opening remarks from Obi, followed by Larry to review the FDA guidance document, followed by Vivek to provide an overview of our commercial strategy, Kevin to review our financial results and then Obi with closing remarks.
Now it's my pleasure to introduce Obi Greenman, Cerus’ President and Chief Executive Officer.
Obi Greenman
Thank you, Tim and good afternoon, everyone. The finalization of the FDA guidance document and coming off of a very successful AABB meeting for Cerus, we believe that we are well positioned to deliver on a new standard of care for platelet transfusion safety in the U.S.
The FDA action to finalize this guidance is not only a watershed moment for transfusion medicine with regard to patient safety, but it is also a major blood safety policy event that has relevance for how global regulatory bodies ensure the safety of platelets. In the U.S.
by the end of the 18 month compliance period, the requirement is that every single one of the 2.6 million platelet units collected each year in the U.S. to be held to a new standard of safety.
One could view this as an obsolescence initiative for all U.S. blood centers and that conventional platelets as currently prepared today will be obsolete in 17 months.
Immediately after the release of the final FDA guidance, the leadership of the American Red Cross validated the important role that INTERCEPT will play in their operations by issuing an open letter to the U.S. healthcare community about their intention to make INTERCEPT platelets broadly available to their hospital customers.
They stated that, “The growing expansion of pathogen reduction technologies grants hospitals and blood providers economical offsets while making safer, ready to transfuse products available for patients. Pathogen reduction is the preferred approach of the American Red Cross for enhancing the safety and availability of platelets for transfusion.”
The purpose of this final FDA guidance document is to provide clear direction to blood centers and hospital transfusion services about how they can meet the requirements specified in the FDA Code of Federal Regulations to ensure that the risks of bacterial contamination of platelets are adequately controlled. After several draft versions of the guidance and multiple Blood Products Advisory Committee meetings on the topic, the FDA finalized the guidance to address fundamental concerns about platelet transfusion safety.
The guidance contains complicated culture-based and secondary rapid testing methods as an alternative to pathogen reduction, even if those testing options require considerable operational and logistical efforts to undertake. With the final guidance document now in place in the U.S., we believe the overall simplicity of the INTERCEPT technology combined with its broad spectrum protection against current and emerging pathogens in the blood supply sets the stage for a multi-years cycle of sales growth.
As a foundation for this expected growth in the U.S. business, we are pleased to report another strong quarter of sales execution with reported revenue growth across all major geographies, despite a currency headwind.
Third quarter product revenue totaled $18 million, a 17% increase on a reported basis with the U.S. market leading the growth.
Having just returned from the AABB meeting in Texas, we thought it would be worthwhile to have our Founder and Chief Scientific Officer, Dr. Larry Corash, walk you through the different options available to blood centers and to illustrate the advantages of INTERCEPT over the other strategies for reduction of bacterial contamination risk detailed in the final FDA guidance document.
Following Larry, Vivek will provide a framework for our commercial strategy for the next 17 months and the discrete actions we are taking to help our customers with this transition.
Laurence Corash
Thanks, Obi and good afternoon. On the next slide, this final guidance is important in defining a new U.S.
standard of care in platelet transfusion safety. Similar to that achieved in France, Belgium, Switzerland, Austria and Kuwait.
The guidance has been vetted by the transfusion medicine community and it defines specific procedures for each option. Each approach will impact blood center and hospital operational logistics, costs and regulatory compliance.
These factors will determine customer decisions to achieve compliance by the deadline of March 31, 2021. Today, the majority of U.S.
blood centers and hospitals are not in compliance, hence action must be taken. The final guidance is a seminal document in U.S.
blood transfusion safety and it makes a compelling case for the clear advantages of INTERCEPT, the only option with safety, logistic and economic benefits beyond reducing the risk of bacterial infection. On the next slide, let me start by outlining the landscape.
The FDA has defined two strategies with options to address bacterial contamination, single step options in the top section and two step options in the lower section. The two step strategies are complex and require multiple procedures, some in the blood center and some in the hospital in order to release platelets for transfusion.
The timing days shown by the top blue bar from day zero to day seven marks the timeline for collection, preparation and transfusion of platelets using the various options. Today, I'll focus my comments on apheresis platelets as they account for 90% of the market and on the single step strategy options as they are the most attractive for hospitals and blood centers.
I'll address specific questions on the two step strategies during Q&A. On Slide 7 to understand the guidance, I'll explain the specific terms important for understanding the various options.
Collection time is the time when an apheresis platelet collection is initiated and it starts the dating period for exploration of platelets. The day of collection is day zero.
Expiration is the last day, platelets can be transfused either three, five or seven days after initiation of collection. Hold time is the period during which platelets are quarantine prior to sampling for bacterial culture and 12 hours after culture before they can be released for transfusion.
This is required to improve the limited sensitivity of bacterial culture testing. There is no hold time for INTERCEPT platelets as bacterial testing is not required for INTERCEPT.
Available transfusion times are the days after release from bacterial testing for pathogen reduction that the platelets can be transfused. Available transfusion time is more relevant than the expiration day.
As all culture testing options require a hold time that decrease available days for transfusion. Sample volumes are the sample amounts taken for bacterial testing and thus not available for transfusion.
On Slide 8 the guidance specifies a sample volume of 16 milliliters per platelet container in two bottles for aerobic and anaerobic culture versus the pre guidance routine sample of 8 milliliters for aerobic culture only. All cultures must be monitored until the end of expiration of the platelet product.
Now on Slide 9 let's focus on the single step strategy options. At AABB we received feedback from hospitals indicating they prefer ready to use platelets that do not require added technical procedures at the hospital.
This is only possible using the single step strategy options. Hence, we expect the majority of the market to opt for a single step strategy.
There are three options available under the single step strategy. The first option is the only FDA approved pathogen reduction system INTERCEPT.
This option has no hold time delay. The earliest release time and available time for transfusion is 5 to 5.5 days shown by the green bar.
The guidance states that centers already using INTERCEPT pathogen reduction need to do no more, they are in compliance. The other two options requiring bacterial culture testing are large volume delayed sampling or LVDS with either 36 or 48 hour hold times after collection and 12 hours of culture incubation before release for transfusion.
LVDS requires a 16 milliliter sample from each platelet unit that's for double and triple dose collections the total loss is 32 and 48 milliliters respectively. The volume loss will impact collection split rates and the number of available platelet doses.
With the LVDS options the earliest possible times for transfusion are 48 to 60 hours after collection, leaving a maximum available transfusion time of 5.5 days, similar to the available transfusion life of INTERCEPT, but at the expense of fresh platelets and with more technical procedures. With LVDS after release, all bacterial cultures must be monitored until expiration.
This will require investment in capital equipment and personnel to manage the increased number of cultures. When a positive culture is detected, the hospitals must withdraw all the split platelet components associated with the positive culture.
If any of these platelets have been transfused, primary care physicians must be alerted, patient's informed and clinical evaluations performed, which may require patient blood cultures or prescription of prophylactic antibiotics. Each of these procedures impacts logistics, adds cost and creates anxiety for patients.
Lastly, my LVDS seven day option is listed in the guidance, the culture device for this option is not currently FDA approved. INTERCEPT offers the following clear advantages over LVDS bacterial testing.
First on Slide 10 this shows the experience from a case study conducted at a U.S. tertiary care Academic Medical Center.
The line in orange shows that the majority of INTERCEPT platelets were transfused on day one and two in comparison to the bacterial tested platelets in blue, which were largely transfused on days four and five. Fresh platelets provide better clinical responses.
Notably, this study compared to INTERCEPT to conventional bacterial culture with LVDS bacterial testing, the average age of platelets at transfusion will be older than five days. Secondly, INTERCEPT provides more comprehensive safety than bacterial testing.
INTERCEPT inactivates bacteria, T-cells, viruses and parasites with the INTERCEPT blood centers can reduce costs by stopping gamma irradiation, CMV serology and tests for Zika and [indiscernible]. As shown on Slide 11, blood centers using INTERCEPT have the most favorable key metrics with no hold time, shortest delay to transfusion, 5 to 5.5 days available for transfusion and no follow-up bacterial cultures.
Given the added benefits of INTERCEPT, blood centers have been able to charge a premium for INTERCEPT platelets. It is unclear if a premium can be charged for LVDS platelets, as this is not a new product, only a more tested platelet component.
The value of INTERCEPT has been validated in routine use over the last decade in Europe by national blood centers for whom patient's safety, cost and logistics were the primary factors in choosing INTERCEPT. INTERCEPT’s prospective ready to use single step technology provides blood centers and hospitals the most cost effective means to improve multiple aspects of patient transfusion safety.
With that, let me turn the call over to Vivek for an overview of our commercial strategy with the guidance document now in hand.
Vivek Jayaraman
Thank you, Larry and good afternoon, everyone. As Obi mentioned, we are encouraged by the continued strong customer uptake of INTERCEPT as demonstrated by our top line results in Q3 2019.
Furthermore, the issuance of the final FDA guidance document that validate our belief that INTERCEPT will become the standard of care. I agree with Obi and Larry that the publication of final guidance is a pivotal event.
Ultimately this will accelerate a change in the standard of care with respect to bacterial safety measures for platelets, and I believe that INTERCEPT will prove to be the preferred method by which both blood centers and hospitals achieve compliance. Last week, at the AABB meeting, I had the opportunity to speak with executives from each of the five largest U.S.
blood centers. The centers combined to serve over 70% of the U.S.
platelet market. Clearly, despite being debated and modified over the past several years, the issuance of a final guidance on September 30 took them all a bit by surprise.
Fortunately for us, the AABB meeting offered an excellent point in time opportunity to engage with the centers, gain a better understanding of how they plan to address the guidance and assure them that we are well positioned to partner with them to incorporate INTERCEPT into their center as their primary approach to compliance. While the guidance readiness of each organization varies accumulate confidence that pathogen reduction will be the preferred approach at both the blood center and hospital level.
For the blood centers, INTERCEPT offers the ability to release platelets earlier, provide hospitals with an innovative solution that addresses more than simply bacteria, and accordingly to realize price uplift, which will improve their platelet margins and economics. From a hospital perspective, with INTERCEPT, they will receive a transfusion ready product with limited to no operational impact.
And most importantly, a technology with a global track record of clinical evidence and supportive patient safety. As we have previously noted, the American Red Cross has fully embraced pathogen reduction as their preferred option and as proactively communicated that to the U.S.
healthcare community. Fundamentally, they state that their approach to guidance starts with patients' safety as their primary motivation and as such INTERCEPT is their clear choice.
During the AABB, we held a pathogen reduction networking meeting with representatives from the five largest blood centers and it was very encouraging to see the ARC continuing to take a strong leadership position with respect to adoption of pathogen reduction technology. With 17 months remaining in the compliance period, we are working diligently with our blood centers partners to ensure that patients gain access to the safest blood available.
Much of this work has been underway for quite some time. More specifically, we are focused on the following key action between now and year end.
First, starting with the big five blood centers, we are working to understand the desired INTERCEPT production level by Q1 2021, and making sure to secure commitments and allocate kit supply accordingly. Second, we are working closely with blood centers to help align their production with hospital demand in order to optimize efficient distribution and use of PR platelets.
Third, utilizing our deployment team, we are actively mapping INTERCEPT production processes and blood center operation in order to optimize compatibility with current platelet collection or modify collection and production processes is needed to enable maximum INTERCEPT production. Four, led by our hospital affairs team, we are formalizing the hospital targeting and onboarding schedule to streamline the transition to INTERCEPT platelets during the compliance period.
Fifth, we have prepared and are actively providing educational materials and economic models to facilitate hospital contracting for INTERCEPT platelets, and to address questions from non-clinical decision makers for motivated to ensure that they're hospital can quickly and economically achieved compliance. These are just a few examples of the work streams in which the commercial team is actively engaged.
In parallel, our operations team has spent the better part of the past 12 to 18 months ensuring that we are guidance ready. For example, we have enhanced our supply chain with both increased inventory levels on hand along with expanded disposable kit manufacturing capacity should we see a significant spike in customer demand.
While, it is still very early in the compliance period, we are encouraged by the initial indications from our blood center customers and the hospitals that they serve. Coming out of the AABB, it was clear that one-step solutions are preferred and on those one-step solutions INTERCEPT confers the greatest benefits to all key stakeholders.
Looking outside of the U.S., we believe the final FDA guidance does have implications for platelets safety policy worldwide. Many regions, for example, the Middle East take their cue with respect to production and quality standards from the AABB.
Given the guidance document, those AABB standards will soon reflect the new best practices in place to comply with the FDA guidance. In addition, the economic benefits and ease of use will be further validated in the context of the coming broad U.S.
INTERCEPT experience. When combined with our experience in France as well as other countries that have adopted INTERCEPT at 100%, we believe that pathogen reduction continues to make strong progress for us becoming the global standard of care.
With our current fourth quarter outlook, 2019 top line revenue will be more than two times that of 2016 sale. Across the world, many more patients now have access to INTERCEPT and the safety benefits that has provide.
Looking forward, I am confident that we have a technology platform that can drive compelling growth and even more importantly, we have the people and plans in place to make that grow the reality. These are certainly very exciting times at Cerus.
With that, let me now hand it over to Kevin to review our financial results.
Kevin Green
Thank you, Vivek, and good afternoon, everyone. Today, we reported third quarter 2019 product revenue of $18 million, up 17% from the $15.4 million recorded during Q3 of last year.
The strength of the U.S. dollar relative to the Euro continues to be a headwind, which impacted the year-over-year growth by approximately 5%.
On a year-to-date basis, product revenue totaled $53.7 million, up 21% compared to the $44 million reported during the first nine months of 2018. Similar to the quarterly revenue results, year-to-date product revenues compared to 2018 were impacted by approximately 6% due to the strengthening of the U.S.
dollar relative to the Euro. Global demand for INTERCEPT continues to increase.
The calculated number of treatable platelet doses increased nearly 20% year-over-year. I’m looking at growth through the first three quarters, the worldwide calculated number of treatable platelet doses increased over 30%.
In terms of product mix sold during the quarter, platelet kit sales accounted for approximately 85% of revenue. During the quarter, we did see slightly more illuminator sales than usual with incremental placements spread globally.
The underlying momentum of our business is running ahead of plan and is expected to accelerate further. However, the FX headwinds, we are facing our persistent.
As such, we are reaffirming our full year product revenue guidance range of $72 million to $75 million, which represents an 18% to 20% growth rate compared to 2018 product revenue. Government contract revenue totaled $4.8 million and $13.6 million for the three and nine-month period ended September 30, 2019 respectively.
These are both up from the $3.9 million and $11.4 million reported during the comparable periods in 2018. Now let's move the discussion to our reported gross margins.
Gross margins on product sales have been continuing to improve throughout 2019. For the quarter, gross margins were 58%, compared to 47% for the prior year period.
The significant improvement was attributable to economies of scale and lower per kit COGS resulting from the increased volume of kits manufactured. Additionally, gross margins improved as a result of the favorable product mix shift to double those platelet kits in France and to a lesser extent ability in FX rates.
On a year-to-date basis, gross margins were 55%, compared to 48% during the first nine months of 2018. We expect gross margins will be sustainable in the mid-50%s for the balance of the year.
I’d now like to discuss operating expenses, which totaled $32.2 million during the quarter, compared to $24.8 million during Q3 of 2018. Of the total, SG&A expenses during the quarter accounted for $16.1 million, compared to $14 million during Q3 2018.
The increase was driven from investments we have made in our supply chain capabilities, which will allow us to more efficiently and effectively supply the expected ramp and demand for INTERCEPT kits. In addition, SG&A expenses were higher during the current period due to the initiated preparatory activities for our anticipated U.S.
pathogen reduced cryoprecipitate launch, as well as higher non-cash compensation costs. On a year-to-date basis, SG&A spending during the first nine months totaled $49 million, compared to $42 million during the first three quarters of 2018.
We expect SG&A to remain stable for the balance of the year. I'm looking ahead, we expect to drive leverage.
Research and development expenses for the quarter totaled $16.1 million, compared to $10.8 million during the prior year. The increase in R&D expenses was largely due to product enhancement initiatives and activities tied to label claim expansion, including extended shelf life of INTERCEPT platelets and our triple dose platelet kits.
In addition, development activities to support our anticipated PMA supplement for pathogen reduced cryoprecipitate as well as activities tied to the development of our red blood cell program drove portions of the increase in R&D. On a year-to-date basis, R&D expenses totaled $43.9 million, compared to $30.1 million during the prior year period.
Net loss for the third quarter totaled $18 million or $0.13 per diluted share compared to a net loss of $14.2 million or $0.11 per diluted share for the prior year period. Year-to-date, net loss was $54.3 million or $0.39 per diluted share, compared to a net loss of $41.4 million or $0.32 per diluted share during the first three quarters of 2018.
In terms of cash used from operations, during the third quarter, we have a special one-time milestone payment to Fresenius Kabi of $6.2 million, which was contractual and has been accrued since 2015. In addition, we've continued to invest in working capital, namely inventory in anticipation of the increased demand.
Going forward, we expect this bill to normalize and grow in line with sales. Therefore, on a pro forma basis, without the investments in working capital from both accounts receivable and inventory and excluding the one-time payment, cash used from operations during the third quarter totaled $11.4 million.
Looking ahead to the fourth quarter, we expect cash use from operations to be closer to $10 million. We ended the third quarter with $85.1 million of cash, cash equivalents and short term investments on hand, which we believe is sufficient to fund operations for at least two years and provide ample runway to execute on our strategy.
In addition, we have increased borrowing options on our debt facility and revolving line of credit. With that, let me turn the call back over to Obi for some closing comments.
Obi Greenman
Thank you, Kevin. I'd like to take a few minutes to provide an update on our two key development programs, pathogen reduced cryoprecipitate and our red blood cell program in Europe and here in the U.S.
First, with regard to our cryo PMA supplement, we're tracking on plan for an FDA submission in the first half of 2020 under our breakthrough device designation. Based on that timing, we expect a possible regulatory approval in the second half of 2020.
In parallel with these efforts, we are building out the infrastructure and the small team to be able to launch the product successfully within the level one and two trauma hospitals in the States initially where we have our manufacturing partnerships. The interest in this product continues to be strong for the treatment of major bleeding events in hospitals.
Turning to our red blood cell program, we're making progress in our effort to validate and glutathione supplier, vendor qualification is on track for the first half of 2020. As it relates to our CE Mark submission, the file is still under review at TUV, our notified body and we are in the process of closing out sections of our submission review.
At this juncture, we still expect our CE Mark review to transition to the medical device regulation process in mid-2020 from the current medical device directive. And as such, we anticipate our final approval timing to be in the 2022 timeframe, unless we realize opportunities to compress the NVR review timing.
In the U.S., enrollment in our two Phase 3 studies, RedeS and ReCePI continues with our goal of getting 10 sites up in enrolling in the ReCePI study by the year end this year. We're tracking to deliver on that goal.
With the final guidance document setting that pace and tempo for INTERCEPT platelet adoption in the U.S. over the coming 17 months, and our plan for INTERCEPT cryo launch in the second half of next year, 2020 is shaping up to be a great year for Cerus.
While we have a lot of work to do over the coming period in 2020 and 2021 to help our customers manage the transition to the FDA guidance compliance. Our mission is to make INTERCEPT the standard of care in the U.S.
is more clearly defined and relevant than ever. We take comfort in the talent of our customer facing team to execute on this plan and our historical track record in facilitating nationwide conversions like in France in the end of 2017.
I believe it's important to convey the optimism that Cerus team has coming out of the AABB meeting. All subset of blood centers and hospitals, we're still developing a strategy for being compliant with the final guidance.
Majority of blood centers have put a stake in the ground around the central role that INTERCEPT will play in their operations. Theranos is now clearly on the Cerus team to help them maximize their production of INTERCEPT platelet component and it facilitate the hospital adoption to ease the transition to a new standard of care in platelet safety.
We're looking forward to a strong close to the year. With that, let me turn it back to the operator for Q&A.
Operator
[Operator Instructions] Your first question comes from the line of Craig Bijou from Cantor Fitzgerald. Craig, your line is now open.
Craig Bijou
Great. Good afternoon, guys.
Thanks for taking the questions. Let me start with the guidance and just a couple on that.
One, I just kind of wanted to see if you guys were surprised by anything that ended up in the final guidance. And then secondly, from your early discussions, and I know you guys have plans to have more discussions and work with some of the centers, but I was wondering if you could maybe provide some details on, what you're hearing from the blood centers that the key decision points?
What are their concerns? How are they weighing the different options?
Obi Greenman
Great. I will handle the first part of that question, Craig.
And then let Vivek hand the second part. So and as far as being surprised by anything, the guidance, I don't think we were, definitely reflected the previous graft.
The one thing that to take note of this, that they did draw distinctions between the one-step and the two-step processes that Larry outlined during the prepared remarks. And I think it clearly coming out of AABB and there was a strong preference for the ones that processes, because the hospitals really don't want to undertake any additional manipulations of the platelets.
And so I think that was – it was good that the FDA outlined the various options, so clearly such that there wasn't any confusion. Maybe Vivek, do you want to handle the second part of the question about what came out of AABB?
Vivek Jayaraman
We've indicated in the past and perhaps the thing that continues to be most encouraging is for some time now, even prior to the guidance when filed the American Red Cross has stated that pathogen reduction technology is not from those are a strategic priority for them. So when we think about the ARC represents nearly 40% of the total U.S.
market. So out of the gate, you're talking about 40% of the market that is clearly behind our technology.
Similarly, we had a number of meetings with executives some of the big five blood centers. And now across the board, we heard from forward interest in adopting PR technology.
I think the thing that folks are trying to work through now is understanding, okay, what are the underlying mechanics that allows us to make those real. So what are the operational things that we need to put in place from a production standpoint, so that we can maximize the INTERCEPT production.
How do we need to think about our hospital contracting and working with hospitals, so they can onboard products, so there are number of work stream that blood centers will need to go through and hospitals as relative sort of adopt to this new standard. But certainly, I came out of that meeting and I think my colleagues would agree feeling really excited about our ability to offer INTERCEPT more patients here in the U.S.
Craig Bijou
Got it. That’s very helpful.
And then just as a follow-up on that, do you guys have talked about the ARC and obviously, they've been at the forefront of adopting INTERCEPT. It's their preferred approach, as evidenced by the open letter.
So that's been driving a lot of your U.S. platelet growth for the last several quarters.
So just wondering to get your thoughts, is there – can that accelerate from this point going forward, so that you can actually see even stronger growth out of the ARC than you have over the last several quarters?
Obi Greenman
I think that can obviously, as we get further granularity into where they want to produce more platelets and what hospital customer demand they want to address first. We'll have the better understanding of that.
But certainly, there is headroom within the ARC to drive accelerated growth. And I do believe that they'll serve as a marker that others will follow as they think about adopting pathogen reduction technologies.
So yes, there's certainly had room for us to drive not only U.S. growth or more specifically growth in the ARC.
Craig Bijou
Great. Thanks.
I'll hop back in the queue.
Operator
Your next question comes from the line of Mathew Blackman from Stifel. Mathew, your line is now open.
Mathew Blackman
Good afternoon, everyone. Thanks for taking the questions.
We're all sitting here trying to think through a framework for how the next 17 months could play out just as you are. And so maybe just in the simplest terms, should we think about a potential adoption acceleration being more backend loaded over the next 17 months, as you said, work through education and contracting and training, et cetera?
Could it be more balanced over the period with let's say the big five existing customers with existing INTERCEPT infrastructure, perhaps ramping faster over that time horizon?
Kevin Green
Yes, clearly, I think that the blood centers will be looking how do they meet the compliance timeline. So I think in that context it will be more backend loaded.
And I think we do feel like there will be an acceleration throughout the period, as you know, sort of the momentum from increasing the overall capacity of INTERCEPT production allows for broader fulfillment of the hospital level. And what we've heard distinctly from the hospitals that have decided to adopt INTERCEPT as they'd like to be 100%.
And so they may not get there by the time – by the end of the compliance period, but that's where they want to go. And clearly as more capacity comes into the system, you'll see acceleration.
So to answer your question completely, I think it will be more backend loaded, but definitely acceleration throughout the period.
Mathew Blackman
Okay. Then just a couple of quick follow-ups.
How important is it now for you to get double sets approved in the U.S. Is that at all gating factor for some of these sites?
And can you remind us of the timing of approval there and then just one more follow-up after that?
Obi Greenman
Yes, so just to be clear, we do have approvals for both single and double sets today. And so what you're probably alluding to as the triple storage kit that we have approved in Europe.
We are anticipating that will be filed, we submitted for approval during the compliance period, actually in the second half of next year. So I think it will be a factor, but ultimately what we've seen, even with the large blood centers like the American Red Cross is that they are able to get close to 70%, 80% compatible with INTERCEPT and maybe even beyond that independent of the TS kit availability.
So I think throughout the compliance period, as I mentioned before, we should have this at the backend of the compliance period. It will –we don't think that'll be gaining.
Mathew Blackman
Okay. And then the last question on the red cell program in Europe, I may be reading a bit too much into your comments.
But I think you said first half 2020 now for qualification of a new supplier. And I think in the past you'd get sort of set it as a mid 2020 timeframe.
So did I hear that right? Or am I just overthinking and if that's the case, is it moving a little bit faster?
Obi Greenman
Well, I think it's moving quickly, but I think what we said in the prepared remarks, maybe I miss spoke, it was mid 2024 having that validated for our CE mark submission. So I think it is moving quickly.
We have two suppliers as I've mentioned historically on previous calls that we're qualifying, but we're happy with the progress we've made today.
Mathew Blackman
All right guys, I'll get back in queue. Thank you so much.
Obi Greenman
Thank you.
Operator
Your next question comes from the line of Josh Jennings from Cowen. Josh, your line is now open.
Unidentified Analyst
[Indiscernible] on for Josh. I appreciate the question.
So, on the pipeline for seven day INTERCEPT platelets, can you remind us the regulatory pathway there and timing of approval? And I guess, how the risk is that approval pathway just considering the experience you have already had in Europe this far?
Obi Greenman
Well, let me answer the first part of that question. I’ll let Larry comment just about the experience that we've had with day six and seven day products in Europe for many, many years.
Right now we're anticipating to file for that approval or submitting that day six, seven claim in the second half of next year. We'd anticipate right now without any clock stops, it would be about 180 day review period.
So again, an approval within sort of timeframe of final compliance. So we think that's a nice added benefit.
That being said, as Larry outlined in the call, from an overall platelet shelf line perspective, we think we've got a strong position relative to the other options, outline in the guidance document just because of the early release of the product and that lead into a 5 to 5.5 shelf life for INTERCEPT. Maybe Larry, a few comments about just the experience we've had in Europe with day seven products.
Laurence Corash
Yes, Josh, we've gained valuable experience particularly in Switzerland where seven day INTERCEPT platelets have been used for quite some time. We just published a paper led by Andy Boser from the Basel Red Cross in transfusion showing, first of all that with the INTERCEPT, they're only transfusing about 16% of day seven platelets.
But these platelets are clinically effective and so that experience really supports what we will do in the United States.

Great. Thank you.

Your next question comes from the line of Catherine Schulte from Baird. Catherine, your line is now open.
Catherine Schulte
Hi. Thanks for the questions.
First you mentioned some incremental illuminator placements in the quarter. Any specific geographies to highlight for those new placements?
Kevin Green
No, not really. They were smattered really throughout the globe.
Nothing in particular, just was a little bit higher than historically given that platelets were 85% of our revenues.
Catherine Schulte
Okay. And then we found a tender that it looks like you guys were awarded earlier this month in Slovenia that could contribute $4.5 million to $5 million spread over the next five years.
Is this a new customer win or just an extension of an existing customer?
Obi Greenman
It’s actually customer had on board for about a decade now, so it was one of the earlier adopters of INTERCEPT and I think we were just happy that, they’re sort of experienced with INTERCEPT throughout that period has been favorable and they're a customer that would like to continue on. And I think they were looking maybe to expand on one other small site within Slovenia, but I think we've had roughly or close to 100% of that market for some time.
Catherine Schulte
Great. Thank you.
Obi Greenman
Nice, Catherine.

Your next question comes from the line of Jacob Johnson from Stephens. Jacob, your line is now open.
Jacob Johnson
Hey, thanks. In the press release you guys talked about platelet doses increasing 70% in the U.S.
this quarter. Just interested how that compares to last quarter or is there any way you can sort of frame up that performance relative to your recent experience?
Just to know how much of an uptick in demand you saw this quarter?
Kevin Green
Yes. I mean, as far as platelet doses relative to kits, it's fairly consistent.
The U.S. continues to grow proportionately.
So, the growth that we reported this quarter as far as number of doses consumed is…
Jacob Johnson
Got it. And then obviously a lot of focus on the potential for top line growth following the guidance.
But could you guys just remind us about the outlook for gross margins as revenues grow? Should we see additional margin expansion opportunities on that line?
And do you need to make any SG&A investment to support the growth outlook?
Kevin Green
We've been making investments to ensure that we can supply the uptake and we'll continue to do that. But as far as margin expansion, I think in our prepared remarks, we said we expect that we would be in the mid-50s for the balance of the year.
As we move into 2020, and of course it's all a function of the top line revenue growth and economies of scale.
Jacob Johnson
Okay. Got it.
And then just last quick question for me. The American Red Cross, I think they had 13 of 17 BLAs last quarter.
Any update on that?
Obi Greenman
They’re still on 13, that's not really a driver right now as far as their overall availability of platelets being shipped out of state. Because the 13 sites that currently have their BLAs are mostly they're big net exports.
So I think we will see additional BlAs throughout the remainder of the year and in the early next, they currently have – I think they're roughly around 22 production sites. So, I think they're getting up to full capacity with regard to the sites that they can run online.
And then just within those sites, what the overall compatibility looks like and how they drive the capacity to be able to meet the hospital demand that's coming.
Jacob Johnson
Got it. Thanks for taking the questions.
Obi Greenman
Yes. Thank you, Jacob.

I’m showing no further questions at this time. I would now like to turn the conference back to Mr.
Tim Lee.
Tim Lee
Thank you again for joining us today and for your interest in Cerus. Next month, we will be participating in the Stephens Conference in Nashville and the Stifel Healthcare Conference in New York.
We hope to see many of you there in person. And also as a reminder, today's slides will be available on our website after the call.
Thanks very much.
