Michael Kauffman
Thank you, Justin and good morning. This is Michael Kauffman, the Chief Executive Officer of Karyopharm.
Before I turn the call over to Sharon, I would like to make a few introductory comments. First, I'm delighted with the progress we're making with selinexor, since it first entered the clinic three years ago.
We and a growing number of enthusiastic physicians are learning a great deal about selinexor’s activity across a wide variety of difficult to treat cancers. In addition, we and the investigators are learning ways to optimize the dose schedule and side effects of selinexor across this broad array of tumors which have permitted some patients to remain on selinexor for over a year, the longest now for more than two years.
The breadth and durability of selinexor’s anticancer activity support the broad ability of nuclear export inhibition for the treatment of neoplastic diseases. We presented data describing the clinical benefit of selinexor across multiple solid and hematologic malignancies at some of the most significant medical conferences in the field of oncology this quarter, including the American Society of Clinical Oncology or ASCO Annual Meeting, the Annual Meeting of the European Hematology Association or EHA and the International Conference on Malignant Lymphoma or ICML.
Sharon will go through the content and importance of these data in more detail as well as provide an update on our clinical progress as we continue to execute our selinexor development plan. We selected four hematological malignancies with high unmet medical need for further study based on response rates and durability observed in our Phase 1 studies.
We have recently initiated enrollment in the fourth of these trials called STORM, a Phase 2 study in patients with quad-refractory multiple myeloma and we’re making steady progress in enrolling patients in the three other trials, including SOPRA in acute myeloid leukemia or AML, SADAL in diffuse large B cell lymphoma, or DLBCL and SIRRT in Richter's transformation. In the fourth quarter of 2016 we look forward to reporting preliminary topline data from SOPRA, SADAL and SIRRT with interim data on STORM in mid-2016.
We continue to observe good clinical activity in these indications and we're making important adjustments to some of our early and later phase trials based upon our continued learning on how to optimize selinexor dosing across different tumor types. Sharon will provide additional detail in a moment but we are now adjusting the selinexor dosing in our SOPRA study, a phase 2b randomized clinical trial of single agent oral selinexor versus physicians’ choice in older patients with relapsed or refractory AML where overall survival is the primary endpoint.
In particular we are reducing the dose in SOPRA by approximately 35% from 55 mgs per meter squared previously now to a fixed dose of 60 mg which corresponds to approximately 35 mgs per meter squared. Dosing will remain twice-weekly and the topline data are now expected in Q4 of 2016 with interim data in mid-2016.
Sharon will also be providing details of our plans to move forward with a phase 2/3 study in patients with liposarcoma. We remain the only clinical stage XPO1 inhibitor and we're gaining a growing understanding of how to optimize the activity of oral selinexor across a variety of cancer indications.
I also want to highlight that we’re making progress with our pipeline beyond selinexor. We have been granted a US patent for KPT-350, an oral SINE compound being developed for the treatment of inflammatory and autoimmune diseases.
This patent which will expire in 2032 covers the composition of matter for KPT-350 as well as certain other compositions and related methods. We have also been granted a US patent for certain SINE compounds, including selinexor and KPT-335 which is also known as Verdinexor.
This patent which will expire in 2032 includes methods for treating viral infections, inflammatory disorders as well as cancer. I will now turn the call over to Dr.
Sharon Shacham to provide an update on our clinical development plans for selinexor and our other SINE compounds. Sharon?
Sharon Shacham
Thank you, Michael. I will now provide you with a detailed update of our clinical development plans for selinexor.
To date over 1000 patients across various hematologic and solid tumor Karyopharm and investigator sponsored studies have been treated with oral selinexor. As Michael mentioned, several patients have remained on single agent selinexor for over 12 months and the longest for over two years.
We continue to observe broad and durable antitumor activity of selinexor in both hematologic and solid tumor cancers, consistent with selinexor’s known mechanism of actions with the novel inhibitor of Exportin 1, also called XPO1. Selinexor’s breadth of activity and novel mechanism of action provides multiple paths to late stage development potential commercialization.
Between company and investigator sponsored trials, there are currently 43 clinical studies listed on ClinicalTrials.gov related to selinexor. We presented highlights from some of these studies with selinexor both the single-agent and in combination in several medical conferences during the quarter and we have submitted abstracts for other during the remainder of the year, including the American Society for Hematology or ASH 2015 Annual Meeting in December.
I will now provide an update on selinexor development activities in three respect: first in haematological malignancies; second, in solid tumor and third, in combination studies that we do not cover elsewhere in this discussion. In hematologic malignancies we are actively enrolling patients in four late stage clinical trials of selinexor.
The first trial called SOPRA or selinexor in older patients with relapsed/refractory AML is enrolling patients older than 60 years of age who have received one trial line of therapy and who are ineligible for intensive chemotherapy and transplantation. The second trial is called SADAL for selinexor against diffuse aggressive lymphoma, is enrolling patients with relapsed/refractory DLBCL.
And the third trial called SIRRT is for selinexor in initial and relapsed/refractory Richter's transformation. Preliminary top-line data from these studies are anticipated in the second half of 2016.
As Michael highlighted, we are continuing to learn how to most effectively manage selinexor. In particular, about one year ago we initiated our Phase 2 SOPRA study in older patients with relapsed/refractory AML while ineligible for intensive chemotherapy or transplantation which shows a selinexor dose of 55 mgs per meter squared which corresponds to about 100 mg in most patients.
The steep dose was the maximum tolerated dose in the AML cohort of our Phase 1 clinical trial in hematological malignancies. In July 2015, we mended SOPRA to reduce the dose from 55mg/m2 to a fixed dose of 60mg, which corresponds to approximately 35 mg/m2, a reduction of approximately 35%.
Dosing will remain twice weekly. This change was implemented based on ongoing safety and tolerability evaluations in the SOPRA study, as well as maturing data from the AML patients in the Phase 1 first-in-human clinical trial of selinexor.
The SOPRA study uses a two-to-one randomization of AML patients to either selinexor or physician's choice. This dose adjustment has been implemented based on ongoing data from the SOPRA itself as well as maturing data from the ongoing Phase 1 study of selinexor in patients with AML.
In the SOPRA study, as of the end of July 2015, there have been eight reports of sepsis in seven patients receiving 55 mg/m2 of selinexor, as compared with two reports of sepsis in two patients receiving physician's choice. Given the two to one randomization, we would expect to see twice as many cases of sepsis on the selinexor arm compared with the physician’s choice arm.
However although the numbers are small, and sepsis is often observed in patients with AML, the incidence of sepsis in these elderly AML patients appears to be higher than that of the controlled arm in the patients receiving selinexor. In contrast, there were 17 cases of febrile neutropenia on the selinexor arm versus 9 on the controlled arm.
That is similar rate. In addition, as our Phase 1 data are maturing, an apparent increase in the incidence of sepsis in patients receiving doses of selinexor at high doses given twice weekly with elapsed/refractory AML was noted in our Phase 1 clinical trial in hematologic malignancies.
Importantly, this increased rate was not observed in patients with other hematological malignancies or with solid tumors and is thus far only observed in elderly AML cases. Furthermore doses of selinexor at 60mg twice weekly were not associated with any increase in sepsis or other infection-related events in patients with heavily pretreated AML in the Phase 1 study.
Finally the majority of the patients with AML in the Phase 1 study who showed a response to selinexor treatment, including patients with complete remissions, received selinexor at doses of approximately 60mg or below. As a result of the change in dose, the SOPRA study will now have an interim assessment in mid-2016 with topline data expected in the fourth quarter of 2016.
Because the apparent increase risk of sepsis at high doses of selinexor were restricted to the AML cohort across our Phase 1 studies, we are continuing to treat patients with both 100 mg and 60 mg doses of selinexor in our SADAL study in patients with relapsed or refractory DLBCL. This study is ongoing and enrolling.
Top line data continue to be expected in the fourth quarter of 2016. In July 2015, we amended the protocol of SIRRT, a Phase 2 clinical study of single-agent, oral selinexor in patients with Richter's transformation, an aggressive form of lymphoma, to include patients with newly diagnosed Richter's transformation.
There is no standard of care for patients with Richter's transformation and these patients have an extremely poor prognosis. As a result of these factors, and in order to improve patient accrual, in consultation with key opinion leaders in the area, we determined that there was a compelling rationale to amend the SIRRT protocol to also include patients who had not yet received chemotherapy to treat Richter's transformation.
We are now implementing the revised protocol across SIRRT study sites in the United States and Europe. Dose of Selinexor in SIRRT continues to be 60 mg twice weekly and has not been altered.
In addition to the studies previously mentioned, we have initiated a single arm Phase 2 study in patients with quad-refractory multiple myeloma called STORM or Selinexor Treatment of Refractory Myeloma. Based on previously reported encouraging data in heavily pretreated patients with multiple myeloma and in consultation with key opinion leaders.
The study will enroll 80 patients as myeloma is refractory to bortezomib, carfilzomib, lenalidomide and pomalidomide. In addition, about 25% of the patients will have myeloma refractory to an anti-CD38 monoclonal antibody such as daratumumab.
Selinexor is being dosed at 80 mg twice weekly equivalent to about 45 mg per meter quarter along with 20 mg of dexamethasone given with each dose of selinexor. If the data from those 80 patients are promising, we may extend the size of the study for potential submission to regulatory authorities.
We plan to present the initial data on these patients in the middle of 2016. We are preparing to initiate a global clinical study to evaluate the combination of selinexor and dexamethasone with backbone therapies including bortezomib, pomalidomide or lenalidomide in patients with multiple myeloma.
The study will be divided into two phases. The first phase will be conducted to determine the maximum tolerated dose of selinexor when combined with these therapies.
The safety of selinexor will also be evaluated when given only once weekly or twice weekly. Once the recommended Phase 2 dose is established, an expansion phase will begin in which additional patients for each treatment arm will be enrolled.
Similarly, we plan to initiate a study of selinexor in combination with rituximab with backbone therapies in patients with DLBCL after multiple relapse by the end of 2015. These backbone therapies include gemcitabine plus oxaliplatin, [indiscernible], lenalidomide and [indiscernible].
Once the recommended Phase 2 dose of the most active combination is identified, it will be carried into an expansion phase in patients with heavily pretreated DLBCL. As Michael mentioned, our enthusiasm for initiating these studies with selinexor in hematological malignancies is supported by selinexor extensive clinical activity which has been presented at multiple medical meetings in the past several months.
For example, we presented clinical data further supporting selinexor potential benefit in the treatment of hematologic malignancies, including selinexor as single agent and in combination with chemotherapy in DLBCL and AML at the recent 28th Congress of the European Hematology Association. This data include updated survival data from an ongoing Phase 1b clinical trial of single agent selinexor in heavily pretreated patients.
In this study, that was DLBCL patients who responded to selinexor demonstrated a median overall survival of greater than 10 months with a median that was not yet reached and progression free survival of 24 months, significantly longer than the 27 DLBCL patients who did achieve a response with an overall survival of 3.5 months and progression free survival of 1.2 months. At the same meeting, preliminary Phase 2 results from an ongoing clinical trial of selinexor in combination with chemotherapy regimen of idarubicin and Ara-C in 18 evaluable patients with relapsed or refractory AML demonstrated a 56% overall response rate, including nine patients with complete remission and one patient with a partial remission.
This preliminary data of selinexor in combination with a very intensive chemotherapy regimen suggests that selinexor will be combinable with a variety of other anti-cancer agents. We also presented clinical and preclinical data from an ongoing Phase 1 clinical trial with single agent selinexor in DLBCL patients with MYC, BCL2 and/or BCL6 translocations, at the 13th International Conference on Malignant Lymphoma or ICML.
DLBCL with these translocations represent an area of significant unmet medical need associated with poor prognosis and limited standard-of-care treatment options. In this study, 14 relapsed, refractory DLBCL patients with triple, double or single hit MYC, BCL2 and/or BCL6 translocations, demonstrated clinically meaningful activity with a 43% overall response rate, meaning a partial response or better, including two complete responses, four partial responses and two additional patients achieving stable disease (SD).
Preclinical data was also presented at ICML that demonstrated selinexor’s potency in double hit DLBCL cell lines in vitro and in an aggressive derived xenograft (PDX) model of triple hit DLBCL, with 84% tumor growth inhibition. On the solid tumor front, we are very pleased to report that we recently met with the FDA concerning the development of selinexor and liposarcoma, particularly difficult to treat cancer with a very limited therapeutic option.
Based on the encouraging data we presented at the ASH in patients with relapsed progressive liposarcoma which I will discuss in a moment, we are planning to initiate a Phase 2/3 study of single agent selinexor versus placebo to treat liposarcoma in the second half of 2015. This trial will utilize a progression free survival of primary end point.
In addition, as you know, Karyopharm is actively enrolling patients in three selinexor Phase 2 solid tumor studies. The first trial, our SIGN study is in gynecological malignancies.
The second trial, our KING Study is in glioblastoma multiforme. And the third trial, our SHIP Study, is in metastatic prostate cancer.
Preliminary data from SIGN and KING studies were presented at ASCO this year. And we will summarize this data shortly.
Our fourth phase 2 solid tumor study involves patients with relapsed or refractory squamous cell tumors. Enrollment to the head and neck cohort of this study has been completed and, due to very slow accrual in the lung and esophageal squamous carcinoma cohorts, we are terminating further enrollment to these arms and finalizing the study.
Additional trials with selinexor in combination with various chemotherapies are ongoing and will include patients with squamous cell carcinomas. We presented positive clinical data with single agent oral selinexor in an ongoing Phase 2 and Phase 1b clinical studies across multiple solid tumors at the most recent ASCO Annual Meeting, including anti-tumor activity and disease control in patients with recurrent glioblastoma, advanced sarcomas, heavily pre-treated gynecological cancers and across multiple malignancies in Asian patients.
Highlights of this data include: in patients with recurrent glioblastoma we reported anti-tumor activity and brain penetration at clinically relevant drug levels, with a 13% overall response rate (ORR) and a 38% disease control rate (DCR). In patients with advanced sarcomas, including liposarcoma, we reported durable anti-cancer activity, including longer progression free survival (PFS) than last prior regimen.
Median PFS for selinexor was 136 days compared with 54 days on the last prior regimen. In heavily pretreated ovarian, endometrial and cervical cancer, we reported promising anti-tumor activity or disease control – with disease control rates of up to 62% and several patients remaining on study for up to 12 months.
And anti-tumor activity in a Phase 1 study evaluating selinexor across a variety of advanced malignancies in Asian patients. In terms of combination studies, there are currently a number of investigator sponsored and company sponsored trials ongoing or planned, evaluating the potential of selinexor in combination with either chemotherapy or targeted agents in both hematologic and solid tumor cancers.
In addition to the studies we discussed earlier, some of the key selinexor combination studies with preliminary data expected within the next year include the following: carfilzomib and dexamethasone in multiple myeloma where preliminary clinical evidence of combination anti-tumor activity was presented at last year’s annual meeting of the American Society of Hematology. Bortezomib and dexamethasone in multiple myeloma in transplant induction has already begun.
In addition, the study of selinexor in combination with bortezomib and dexamethasone in patients with at least one pile therapy with myeloma is not refractory to bortezomib is expected to begin in the second half of 2015. Cytarabine in AML which began in 2014 and carboplatin and paclitaxel in patients with relapsed or refractory ovarian or endometrial cancers which has initiated enrollment.
Additional combination studies in both solid and hematologic malignances have commenced or will begin shortly. A full list of ongoing and pending studies is available at clinicaltrials.gov.
In conclusion, we are quite pleased with the interest in and progress with selinexor across a very broad array of malignancies. Our program is now moving to include combination studies with a diverse set of anti-cancer agents all of which are based on strong clinical mechanisms and xenograft support.
We look forward to continue to provide you with updated results as they become available. Now I will turn the call over to Justin.
Justin Renz
Thank you Sharon. Since we issued a press release earlier today outlining our second quarter ended June 30, 2015 financial results, I'll just review the highlights and then speak to our cash balance and our financial guidance.
Karyopharm reported a net loss of $32.7 million or $0.92 per share for the quarter ended June 30, 2015 that compares with a net loss of $16.4 million or $0.56 per share for the same period in 2014. We recognized stock-based compensation expense of $4.5 million and $3.9 million for the quarters ended June 30, 2015 and 2014 respectively.
Our second quarter net cash burn from operating activities was approximately $28.2 million. Research and development expense was $27 million in the second quarter of 2015, compared to $13.2 million for the same period in the previous year while general and administrative expenses were $6.2 million in the second quarter of 2015, compared to $3.3 million in the second quarter of last year.
This increase in expenses is primarily related to the significantly expanded clinical development activities for our lead drug candidate Selinexor which Sharon just highlighted and the increase in general and administrative expenses resulting primarily from an increase in personnel costs, including headcount and stock-based compensation expenses along with the additional cost of operating as a public company. Cash, cash equivalents and investments as of June 30 totaled $256 million, compared to $285.3 million as of March 31.
Based on our current operating plans, we expect our cash will fund our R&D programs and operations into 2018, including moving our later phase clinical studies to their next data inflection points. We expect to end 2015 with a cash balance greater than $200 million.
I'll turn the call back over to Michael to provide a brief summary before we take some questions.
Michael Kauffman
Thank you, Justin. In summary, we continue to make strong progress evaluating the vast potential of XPO-1 inhibition as our aggressive selinexor development program continues in 2015 and beyond.
After demonstrating the single agent activity of selinexor in solid tumors at ASCO in June, we’ve submitted a number of abstracts for consideration to the American Society of Hematology which is holding its annual meeting in Orlando, Florida later this year. There we look forward to sharing with you the breadth, depth and combinability of selinexor in difficult to treat hematological indications.
With that, operator, we are ready to take questions. Operator?
Operator
[Operator Instructions] And our first question comes from the line of Mike King of JMP Securities.
Mike King
I had a few, so I will try to just keep it to the most pertinent. I would love a little bit more elaboration if you could on AML, just as far as the level of neutropenia seen upon enrollment in these patients, is it comparable to the other levels of neutropenia in your other hematologic malignancy trials or does it have anything to do with prior therapy et cetera?
Any clues that you might help us with to understand where the increased incidence of sepsis coming in this population versus any of your other patient populations?
Sharon Shacham
Patients with AML, especially the elderly AML has significant higher number of sepsis. They are very sensitive to both sepsis and febrile neutropenia as we mentioned, as well as other infections.
We analyze all the data and based on our data from SOPRA study, the level of other infection as well as febrile neutropenia is similar between selinexor and the physician’s choice arm. However as we mentioned in the study, the rate of incidence of sepsis was higher on the selinexor arm versus physician choice.
And this was selective to sepsis and not to other types of infections. When we analyze the doses, based on the Phase 1 data it seems that this occurs only at doses – only at high dosage around 100 mg or 55 mg per meter square.
Mike King
Right, I got that but is this because – if those higher doses are creating a greater levels of neutropenia or what is the punitive trigger for that?
Michael Kauffman
Yes, just to clarify, I mean patients with AML unlike the patients on our other studies come in with grade 3 or 4 neutropenia, many of them have almost no normal neutrophils, they have blasts which are not effective against infection. So essentially everyone coming into any AML study has almost no functioning normal neutrophils.
So they start off with neutropenia. As you noted the febrile neutropenia rates on both arms were the same, selinexor is fairly selective for leukemic blasts over normal neutrophils but if you have no normal neutrophils it’s not going to matter.
Mike King
And these are patients that are normally prophylaxis as well [indiscernible] –
Sharon Shacham
Yes and for example in the cell study as we reported at the last EHA – and these are in-patients with relapsed or refractory AML, when we treated selinexor even with high dose chemotherapy we did not see an increase in sepsis based on the small number of patients on this study.
Mike King
Switching very quickly to sarcoma, Sharon, you said in the formal remarks that the end point is going to be PFS. Can you say anything about – I assume these are patients that are going to come in previously untreated or whether they have had some prior docs or some other active agent and maybe tell us about the size of the study if you can and what expected PFS might be?
Sharon Shacham
So the population of the study will be patients with liposarcoma with one prior therapy, or more. In terms of the PFS, we expect about three months improvement in PFS in patients treated with selinexor versus placebo.
Mike King
And the placebo PFS would be expected to be what roughly?
Sharon Shacham
Around two months. Two to three months, the cycle in this study will be six weeks, so it will happen around every six weeks.
Mike King
And then the number of patients you expect to enroll?
Sharon Shacham
It’s about 200, randomization will be two to one on selinexor versus placebo and we will allow cross over from placebo to selinexor after –
Mike King
You will allow crossover?
Sharon Shacham
Yes.
Operator
Thank you and our next question comes from the line of Michael Schmidt of Leerink Partners.
Jonathan Chang
Hi, it’s Jonathan Chang stepping in for Michael Schmidt. Thanks for taking my questions.
I am curious – could you talk about your confidence in the 60 mg fixed dosing in AML and also about your experience with the 60 mg fixed dose across the indications?
Sharon Shacham
Sure. Actually now we have evaluated 60 mg and it is the dose that we are using in the majority of our studies.
We evaluated the level of the other side effects such as anorexia, fatigue, and those at 60 mg and responded to be a very tolerated dose while maintaining efficacy rate when we look at the accumulating data in both solid tumors and hematological malignancies. Specifically in AML, both in the patients, the small number of patients in the SOPRA study that we have seen 60 mg as well as data from the Phase 1 study, we didn’t see an increase in sepsis rate in this dose.
Jonathan Chang
And I think you mentioned it before but I might have missed it. But can you remind me was there any sepsis observed in the AML combination study presented at EHA and what the dosing regimen was there?
Sharon Shacham
At the cell study which is the only study in combination that we published so far, we used selinexor in combination with seven and three, the dose of selinexor there was 40 mg per meter square and there was no – it’s a small dose, small number of patients that we published, at the EHA, this was an interim analysis but in this small number of patients, we didn’t see an increase in sepsis rate. Just as a reminder, these are in-patients, all are treated prophylactic with antibiotic, anti-fungal and other.
Jonathan Chang
And maybe just last one, I am curious to know when the sepsis occurred during the course of treatment?
Sharon Shacham
So it’s a very good question, Michael. When we look at the data it can happen very early as expected in elderly patients with relapsed AML, or it can happen in cycle two, cycle three and so on.
So there wasn’t specific timing of the sepsis.
Operator
Thank you and our final question comes from the line of Arlinda Lee of MLV.
Arlinda Lee
Actually on the ASH data that you guys presented abstract or has submitted abstracts for, can you maybe comment on what kinds of durability response data you have and tolerability particularly for AML and if you will have additional information on the abstract signal that you guys are seeing there?
Sharon Shacham
Arlinda, I guess, you will have to wait a month or two until the abstracts with the ASH will be available in two or three months, we can’t disclose this at this point as the abstracts were either accepted – we don’t know if they were accepted or not. And they are not available.
Arlinda Lee
Would we be seeing information, additional information on the sepsis signal –
Sharon Shacham
At the upcoming ASH, there is no update on SOPRA study specifically. There will be updates of other ISDs and they will include both safety and tolerability.
End of Q&A
Operator
Thank you. I am showing no further questions at this time.
Michael Kauffman
Thank you very much, operator. With that, we will close the call.
This concludes our second quarter 2015 conference call and thank you all for participating and we will speak with you soon.
Operator
Ladies and gentlemen thank you for participating in today’s conference. This concludes the program.
You may all disconnect. Everyone have a great day.
