Karyopharm Reports New and Updated Selinexor Combination Data from the Phase 1b/2 STOMP Study at the European Hematology Association 2019 Annual Meeting

On June 14, 2019 Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, reported three presentations highlighting new and updated data from the Phase 1b/2 STOMP (Selinexor and Backbone Treatments of Multiple Myeloma Patients) study evaluating selinexor, the Company’s first-in-class, oral Selective Inhibitor of Nuclear Export (SINE) compound, and dexamethasone in combination with standard approved multiple myeloma (MM) therapies, Kyprolis (carfilzomib), Darzalex (daratumumab), or Pomalyst (pomalidomide), in patients with previously treated multiple myeloma. The data will be featured in oral and poster presentations at the European Hematology Association (EHA) (Free EHA Whitepaper) 2019 Annual Meeting taking place June 13-16, 2019 in Amsterdam (Press release, Karyopharm, JUN 14, 2019, View Source [SID1234537085]).

"Preliminary data from the Kyprolis arm of the Phase 1b/2 STOMP study show early but encouraging clinical activity, including two patients who achieved a complete response, along with an expected and manageable tolerability profile, in patients with heavily pretreated, double-refractory Kyprolis-naïve multiple myeloma," said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. "Additionally, the Darzalex and Pomalyst arms of the STOMP study continue to demonstrate impressive response rates, including encouraging rates of very good partial responses (VGPR), which indicate a 90% or greater reduction in a patient’s disease burden."

New Phase 1b/2 STOMP Study Data: Selinexor plus Kyprolis and Low-dose Dexamethasone (SKd)

In this arm of the Phase 1b/2 STOMP study, oral selinexor (dosed once weekly) is being evaluated in combination with Kyprolis (56mg/m2 or 70mg/m2 once weekly) and low dose dex (orally, 40mg once weekly or 20mg twice weekly) in patients with relapsed refractory MM who have received at least two prior therapies, which can include previous treatment with a proteasome inhibitor (PI), one or more immunomodulatory drugs (IMiDs: Revlimid, Pomalyst) or Darzalex. All patients on the study had previously received both PIs and IMiDs. The following table is a summary of the efficacy results:

Best Responses1 in Evaluable SKd Patients as of 1-May-20192
Category N ORR CR VGPR SD
All (Kyprolis-naïve) 9 7 (78%) 2 (22%) 5 (56%) 2 (22%)
Key: ORR=Overall Response Rate (CR+VGPR+PR); SD= Stable Disease
1 Responses were adjudicated according to the International Myeloma Working Group criteria
2 Based on interim unaudited data

Among the 9 patients evaluated for safety as of the data cutoff date, the most common treatment-related AEs were cytopenias, along with gastrointestinal and constitutional symptoms; most were manageable with dose modifications and/or standard supportive care. The most common non-hematologic treatment-related AEs were nausea (67%), fatigue (44%), hyperglycemia (44%), anorexia (33%) and vomiting (33%), and were mostly Grade 1 and 2 events. As expected, the most common treatment-related Grade 3 and 4 AEs were hematologic AEs and included thrombocytopenia (78%), leukopenia (33%), anemia (22%) and neutropenia (22%). Dose limiting toxicities, including Grades 3 and 4 thrombocytopenia, Grade 3 pneumonia and Grade 3 vomiting, were observed in patients receiving selinexor 80mg and Kyprolis 70mg/m2 and selinexor 100mg and Kyprolis 56mg/m2. No DLTs were reported in the selinexor 80mg and Kyprolis 56mg/m2 cohort, and therefore, confirmation of the recommended Phase 2 dose (RP2D) is ongoing with this dosing regimen.

Updates on Phase 1b/2 STOMP Study: SDd and SPd

Selinexor plus Darzalex and Low-dose Dexamethasone (SDd)

In this arm of the Phase 1b/2 STOMP study, oral selinexor (dose escalated using either 100mg once weekly or 60mg twice weekly) is being evaluated in combination with Darzalex (16mg/kg intravenously once weekly) and low dose dexamethasone (dex; orally, 40mg once weekly or 20mg twice weekly) in patients with relapsed or refractory MM who received at least three prior lines of therapy, including a PI and an IMiD, or patients with MM refractory to both a PI and an IMiD. The following table is a summary of the updated efficacy results:

Best Responses1 in Evaluable SDd Patients as of 1-May-20192
Category N3 ORR VGPR PR4
Darzalex naïve 30 22 (73%) 11 (37%) 11 (37%)
All 32 22 (69%) 11 (34%) 11 (34%)
Key: ORR=Overall Response Rate (VGPR+PR); PR= Partial Response
1 Responses were adjudicated according to the International Myeloma Working Group criteria
2 Based on interim unaudited data
3 Two patients were not evaluable for response as they withdrew consent prior to disease follow up
4 Two unconfirmed PRs

Despite the heavily pretreated nature of the patients in the study, with 100% of the patients having dual- (PI and IMID)-refractory disease, only one patient (3%) did not have at least a minimal response. Median progression-free survival (PFS) has not been reached. Among patients with at least a PR, the median time on treatment was 7.7 months, while the median time on study for all evaluable patients was 4.8 months. Median time to response was 1.0 month. Based on published data, the expected ORR for Darzalex therapy without selinexor in the Darzalex-naïve population is ~29%. Thus, the ORR of 73% continues to provide a basis for further evaluation of the SDd combination.

Among the 31 patients evaluated for safety as of the data cutoff date, the most common treatment-related AEs were cytopenias, along with gastrointestinal and constitutional symptoms; most manageable with dose modifications and/or standard supportive care. The most common non-hematologic treatment-related AEs were nausea (68%), fatigue (58%), anorexia (32%), insomnia (32%), diarrhea (32%), hyponatremia (32%), and vomiting (26%), and were mostly Grade 1 and 2 events. As expected, the most common Grade 3 and 4 treatment-related AEs were hematologic AEs and included thrombocytopenia (42%), anemia (29%), leukopenia (26%) and neutropenia (23%). No Grade 5 AEs were reported. Based on these tolerability and efficacy data, the recommended RP2D of SDd is selinexor (100mg orally, once weekly), Darzalex (16mg/kg, once weekly) and dex (40mg orally, once weekly).

Selinexor plus Pomalyst and Low-dose Dexamethasone (SPd)

In this arm of the Phase 1b/2 STOMP study, oral selinexor (60mg or 80mg once weekly or 60mg or 80mg twice weekly) is being evaluated in combination with Pomalyst (2mg, 3mg or 4mg orally, once daily) and low dose dex (orally, 40mg once weekly or 20mg twice weekly) in patients with relapsed or refractory MM who received at least two prior lines of therapy, including a PI and an IMiD, or patients with MM refractory to both a PI and an IMiD. The following table is a summary of the efficacy results:

Best Responses1 in Evaluable SPd Patients as of 1-May-20192
Prior Therapy Status N3 ORR VGPR PR4 Median PFS
Pomalyst-naïve and Revlimid refractory or relapsed 30 17 (57%) 7 (23%) 10 (33%) 12.2 months
Pomalyst and Revlimid refractory 10 3 (30%) - 3 (30%) 4.2 months
All 40 20 (50%) 7 (18%) 13 (33%) 10.4 months
Key: ORR=Overall Response Rate (VGPR+PR)
1 Responses were adjudicated according to the International Myeloma Working Group criteria
2 Based on interim unaudited data
3 Five patients not evaluable for response: one death unrelated to myeloma, one non-compliance with study procedures, two withdrawal of consent before disease follow up, one patient on treatment pending response evaluation
4 One unconfirmed PR

Among the 45 patients evaluated for safety as of the data cutoff date, the most common treatment-related AEs were cytopenias, along with gastrointestinal and constitutional symptoms; most manageable with dose modifications and/or standard supportive care. The most common non-hematologic treatment-related AEs were nausea (56%), fatigue (53%) and anorexia (49%) and mostly Grade 1 and 2 events. As expected, the most common treatment-related Grade 3 and 4 AEs were hematologic AEs and included neutropenia (56%), thrombocytopenia (31%), anemia (31%) and leukopenia (16%). There were three Grade 5 treatment-related events (febrile neutropenia, intracranial hemorrhage and pneumonia). Determination of the RP2D is still ongoing.

About Selinexor

Selinexor is a first-in-class, oral Selective Inhibitor of Nuclear Export (SINE) compound. Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. In 2018, Karyopharm reported positive data from the Phase 2b STORM study evaluating selinexor in combination with low-dose dexamethasone in patients with triple class refractory multiple myeloma who have been previously exposed to all five of the most commonly prescribed anti-myeloma therapies currently available. Selinexor has been granted Orphan Drug Designation in multiple myeloma and Fast Track designation for the patient population evaluated in the STORM study. Karyopharm’s New Drug Application (NDA) seeking accelerated approval has been accepted for filing and granted Priority Review by the FDA, and oral selinexor is currently under review by the FDA as a possible new treatment for patients based on data from the STORM study. The Company has also submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) with a request for conditional approval. Selinexor is also being studied in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). In 2018, Karyopharm reported positive top-line results from the Phase 2b SADAL study evaluating selinexor in patients with relapsed or refractory DLBCL after at least two prior multi-agent therapies and who are ineligible for transplantation, including high dose chemotherapy with stem cell rescue. Selinexor has received Fast Track designation from the FDA for the patient population evaluated in the SADAL study. Selinexor is also being evaluated in several other mid-and later-phase clinical trials across multiple cancer indications, including in multiple myeloma in a pivotal, randomized Phase 3 study in combination with Velcade (bortezomib) and low-dose dexamethasone (BOSTON), as a potential backbone therapy in combination with approved therapies (STOMP), in liposarcoma (SEAL), and an investigator-sponsored study in endometrial cancer (SIENDO), among others. Additional Phase 1, Phase 2 and Phase 3 studies are ongoing or currently planned, including multiple studies in combination with approved therapies in a variety of tumor types to further inform Karyopharm’s clinical development priorities for selinexor. Additional clinical trial information for selinexor is available at www.clinicaltrials.gov.

BerGenBio presents preliminary Phase II clinical data at EHA 24: bemcentinib in combination with low dose chemotherapy yields durable responses in AML patients unfit for intensive chemotherapy

On June 14, 2019 BerGenBio ASA (OSE:BGBIO) reported data showing significant efficacy in a Phase II clinical trial (BGBC003, NCT02488408) evaluating bemcentinib, a first-in-class selective oral AXL inhibitor, in combination with low-dose cytarabine (LDAC) as a potential new treatment regimen for AML patients unfit for intensive therapy (Press release, BerGenBio, JUN 14, 2019, View Source [SID1234537084]). The data will be presented by Professor Bjørn Tore Gjertsen MD PhD, Haukeland University Hospital and University of Bergen, at the 2019 annual congress of the European Hematology Association (EHA) (Free EHA Whitepaper) (EHA24), in Amsterdam, The Netherlands, Friday, June 14, 2019.

In total, 16 patients were enrolled into the trial. Among the 14 patients evaluable for efficacy, 6 responses have been reported; 4 patients achieved complete remission / complete remission with incomplete hematologic recovery (CR/CRi) and 2 patients achieved partial remission (PR). Five of the six responses occurred among elderly AML patients (>75 years). Furthermore, two patients achieved durable stable disease for more than 3 months. The relapse-free survival rate for patients with CR/CRi is 7.9 months (range: 0.7 to 9.6 months) and continues to mature. The combination treatment of bemcentinib and LDAC was overall well-tolerated; the most common adverse events (>15% of patients) included anaemia, neutropenia and diarrhoea. Soluble protein (e.g. sAXL) and gene expression biomarker data is still maturing and will be reported in due course. A second biomarker poster from Prof. Gjertsen’s group, to be presented on June 15th, examined the effect of bemcentinib monotherapy from a phase 1b/2 clinical trial on patient AML cell signal transduction using mass cytometry. The high-dimensional single cell-level signalling analysis of AML blasts from 6 evaluable patients revealed significant effects already at 4 hours post-dosing of bemcentinib

Professor Bjørn Tore Gjertsen commented: "These early results are encouraging, especially among less fit AML patients with comparatively poor prognosis. Bemcentinib in combination with LDAC resulted in a substantially higher ORR than expected for single-agent cytarabine and clearly warrant further investigation of bemcentinib in an expansion cohort of AML patients unfit for intensive chemotherapy. Our signal cell-level biomarker analysis of AML blasts from patients indicates a substantial effect on cell signalling and represents a potential new biomarker strategy."

Richard Godfrey, Chief Executive Officer of BerGenBio, commented: "There are currently limited treatment options for AML patients unable to tolerate intensive chemotherapy, particularly those with relapsed and refractory disease. These promising preliminary data with bemcentinib in combination with low-dose cytarabine, reinforce data we recently at presented at ASCO (Free ASCO Whitepaper), and suggests that the addition of our selective AXL inhibitor can substantially improve AML patient outcomes. I am particularly encouraged by the high response rate observed in all patient groups studied, the extended duration of responses seen, which is still maturing, and how well the combination therapy was tolerated. We are still waiting on much of our biomarker data before we can report that and are very excited by cell signalling data presented by our collaborators at the University of Bergen. We will expand this study to include more patients and report more complete data in the coming months.¨

About AML and the BGBC003 trial
Acute myeloid leukaemia (AML) is a rapidly progressing blood cancer. AML is the most common form of acute leukaemia in adults, where malignant AML blasts interfere with the normal functioning of the bone marrow leading to a multitude of complications like anaemia, infections and bleeding. AML is diagnosed in over 20,000 patients in the US annually and is rapidly lethal if left untreated. Successful treatment typically requires intensive therapy or bone marrow transplantation, and relapse and resistance are common. Consequently, there is an urgent need for effective novel therapies in relapsed/refractory patients, particularly those that are ineligible for intensive therapy or bone marrow transplant.

The BGBC003 trial is a phase Ib/II multi-centre open label study of bemcentinib in combination with cytarabine (part B2) and decitabine (part B3) in patients with AML who are unsuitable for intensive chemotherapy as a result of advanced age or existing-co-morbidities. Up to 28 patients will be enrolled at centres in the US, Norway, Germany and Italy.

For more information please access trial NCT02488408 at www.clinicaltrials.gov.

About AXL
AXL kinase is a cell membrane receptor and an essential mediator of the biological mechanisms underlying life-threatening diseases. In cancer, AXL suppresses the body’s immune response to tumours and drives cancer treatment failure across many indications. AXL inhibitors, therefore, have potential high value at the centre of cancer combination therapy, addressing significant unmet medical needs and multiple high-value market opportunities. Research has also shown that AXL mediates other aggressive diseases.

About Bemcentinib
Bemcentinib (formerly known as BGB324), is a potentially first-in-class selective AXL inhibitor in a broad phase II clinical development programme. Ongoing clinical trials are investigating bemcentinib in multiple solid and haematological tumours, in combination with current and emerging therapies (including immunotherapies, targeted therapies and chemotherapy), and as a single agent. Bemcentinib targets and binds to the intracellular catalytic kinase domain of AXL receptor tyrosine kinase and inhibits its activity. Increase in AXL function has been linked to key mechanisms of drug resistance and immune escape by tumour cells, leading to aggressive metastatic cancers.

Aura Biosciences to Present Interim Phase 1b/2 Clinical Data for AU-011 at the European Society of Ophthalmology 2019 Congress

On June 14, 2019 Aura Biosciences, a leader in the development of novel targeted therapies in ocular oncology, reported that interim clinical data from its ongoing Phase 1b/2 clinical trial evaluating the safety and efficacy of light-activated AU-011, the Company’s lead product candidate for the treatment of primary choroidal melanoma, will be highlighted in an oral presentation at the European Society of Ophthalmology 2019 Congress being held June 13-16, 2019, in Nice, France (Press release, Aura Biosciences, JUN 14, 2019, View Source [SID1234537083]).

"The data with additional follow up time continues to demonstrate a good tolerability and safety profile of light-activated AU-011 at single and multiple administrations. There is also consistent evidence of tumor control and visual acuity preservation, which are key benefits of this novel treatment," said Ivana K. Kim, M.D., Co-Director, Ocular Melanoma Center, Massachusetts Eye and Ear, Associate Professor of Ophthalmology, Harvard Medical School. "Interest in AU-011 as a potential first line treatment for early stage disease is very high as current treatments for primary choroidal melanoma typically result in severe vision loss and ocular morbidity."

Oral presentation details are as follows:

Title: Interim Results of a Phase 1b/2 Open-Label Clinical Trial of AU-011 for the Treatment of Small to Medium Choroidal Melanoma

Presenter: Ivana K. Kim, M.D., Co-Director, Ocular Melanoma Center, Massachusetts Eye and Ear and Associate Professor of Ophthalmology, Harvard Medical School

About Choroidal Melanoma

Choroidal melanoma is a rare and aggressive type of eye cancer. Choroidal melanoma is the most common primary intraocular tumor in adults and develops in the uveal tract of the eye. No targeted therapies are available at present, and current radiotherapy treatments can be associated with severe visual loss and other long-term sequelae such as dry eye, glaucoma, cataracts and radiation retinopathy. The most common current treatment is plaque radiotherapy, which involves surgical placement of a radiation device on the exterior of the eye over the tumor. The alternative is enucleation, or total surgical removal of the eye. Choroidal melanoma metastasizes in approximately 50 percent of cases with liver involvement in 80-90% of cases and, unfortunately, metastatic disease is universally fatal (source: OMF). There is a very high unmet need for a new vision sparing targeted therapy that could enable early treatment intervention for this life-threatening rare disease given the lack of approved therapies, and the comorbidities of radioactive treatment options.

About Light-Activated AU-011

AU-011 is a first-in-class targeted therapy in development for the treatment of primary choroidal melanoma. The therapy consists of proprietary viral-like particle bioconjugates (VPB) that are activated with an ophthalmic laser. The VPBs bind selectively to unique receptors on cancer cells in the eye and are derived from technology originally pioneered by Dr. John Schiller of the Center for Cancer Research at the National Cancer Institute (NCI), recipient of the 2017 Lasker-DeBakey Award. Upon activation with an ophthalmic laser, the drug rapidly and specifically disrupts the cell membrane of tumor cells while sparing key eye structures, which may allow for the potential of preserving patients’ vision and reducing other long-term complications of radiation treatment. AU-011 can be delivered using equipment commonly found in an ophthalmologist’s office and does not require a surgical procedure, pointing to a potentially less invasive, more convenient therapy for patients and physicians. AU-011 for the treatment of choroidal melanoma has been granted orphan drug and fast track designations by the U.S. Food and Drug Administration and is currently in clinical development.

Aptose Presents New Preclinical Data for CG-806 at the 24th Congress of the European Hematology Associat

On June 14, 2019 Aptose Biosciences Inc. ("Aptose" or the "Company") (NASDAQ: APTO, TSX: APS), a clinical-stage company developing highly differentiated therapeutics targeting the underlying mechanisms of cancer, reported that new preclinical data for CG-806, its oral, first-in-class pan-FLT3/pan-BTK inhibitor, is being presented in a poster presentation today at the 24th Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) in Amsterdam, the Netherlands (Press release, Aptose Biosciences, JUN 14, 2019, View Source [SID1234537082]).

The poster, CG-806, preclinical in vivo efficacy and safety profile as a pan-FLT3 / pan-BTK inhibitor, highlights the in vivo anti-leukemic efficacy of CG-806 and its GLP toxicology and toxicokinetic profile. In a preclinical MV4-11 FLT3-ITD AML xenograft mouse model, CG-806 suppressed leukemia growth at all doses tested throughout the 28-day period of dosing. After dosing was halted, tumors treated with 10 mg/kg and 30 mg/kg resumed growth but responded again when CG-806 dosing was restarted. In the mice treated with 100 mg/kg, 5 of 11 (45%) were cured through day 120, and in the 300 mg/kg group, 10 of 11 (91%) of the mice were cured. Retreating the "uncured’ mice in these two dose groups for an additional 28 days beginning on day 88 led to rapid and robust antitumor response resulting in "cures" in all retreated mice through day 120. In the "re-treated" mice, no drug resistance and no toxicities were observed. GLP 28-day toxicology and TK studies mice and dogs showed no adverse CG-806-related effects on body weight, ophthalmic, respiratory or neurological examinations, clinical pathology (coagulation, clinical chemistry, or urinalysis), organ weight or macroscopic evaluations. No CG-806-related cardiovascular effects were noted in the 28-day GLP toxicology study or in a separate preclinical cardiovascular safety study.

The poster and abstract can be accessed here or at the publications and presentations section of Aptose’s website www.aptose.com.

"The wealth of preclinical data supporting CG-806 continues to grow and differentiate the molecule from other drugs on the market or in development," said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer. "We are pleased to have reached the clinic with this compound and are hopeful that clinical testing will prove it to be an effective therapy for hematologic malignancy patients greatly in need of new treatment options."

About CG-806
CG-806 is an oral, first-in-class pan-FLT3/pan-BTK multi-cluster kinase inhibitor in Phase 1 clinical development for hematologic malignancies. This small molecule, in-licensed from CrystalGenomics Inc. in Seoul, South Korea, demonstrates potent inhibition of wild type and all mutant forms of FLT3 (including internal tandem duplication, or ITD, and mutations of the receptor tyrosine kinase domain and gatekeeper region), cures animals of acute myeloid leukemia (AML) tumors in the absence of toxicity in murine xenograft models, and represents a potential best-in-class therapeutic for patients with AML. Likewise, CG-806 demonstrates potent, non-covalent inhibition of the wild type and Cys481Ser (C481S) mutant forms of the BTK enzyme, as well as other oncogenic pathways operative in B cell malignancies, suggesting CG-806 may be developed for various B cell malignancy patients (including CLL/SLL, FL, MCL, DLBCL and others) that are resistant/refractory/intolerant to covalent BTK inhibitors. Because CG-806 targets key kinases/pathways operative in malignancies derived from the bone marrow, it is in development for B-cell cancers and AML.
