"In the Phase 2 portion of the SEAL study, patients treated with oral selinexor achieved progression-free survival (PFS) of 5.5 months, compared to 2.7 months for placebo-treated patients, an increase of 2.8 months," said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. "Dedifferentiated liposarcoma is particularly difficult to treat because it is resistant to both standard chemotherapy and radiation and there is a significant unmet need for therapies with a novel mechanism that can help these patients with few effective treatment options. The Phase 3 portion of the SEAL study is currently ongoing and we are anticipating top-line data by the end of 2019. Other selinexor data presented at ASCO (Free ASCO Whitepaper) from ongoing investigator-sponsored research continue to highlight early signs of clinical activity and good tolerability when selinexor is combined with approved agents in soft tissue sarcoma (STS) and acute myeloid leukemia (AML), and additional compelling evidence for selinexor’s potential combinability with checkpoint inhibitors, in this case in AML."

Phase 2 Portion of the Phase 2/3 SEAL Study Evaluating Selinexor in Patients with Liposarcoma

In the poster presentation titled, "Phase 2 results of selinexor in advanced dedifferentiated (DDLS) liposarcoma (SEAL) study: A phase 2/3, randomized, double blind, placebo controlled cross-over study," (Abstract #11512) Mrinal Gounder, MD, Memorial Sloan Kettering Cancer Center, Weill Cornell Medical College and lead investigator of the SEAL study, presented detailed clinical data from the successful Phase 2 portion of the randomized, double-blind, placebo-controlled Phase 2/3 SEAL study evaluating oral selinexor (60mg twice weekly) in 56 patients with previously treated, advanced unresectable dedifferentiated liposarcoma (median 2 prior regimens (range 1-9)). Patients on placebo with confirmed progressive disease are permitted to cross over to the selinexor treatment arm.

For the primary endpoint of PFS, oral selinexor showed superiority over placebo, achieving a median PFS of 5.5 months, compared to 2.7 months for placebo with a hazard ratio (HR) of 0.67, representing a 33% reduction in the risk of progression or death. PFS was assessed by Independent Central Radiological Review based on RECIST v1.1. Additional efficacy assessments included PFS by World Health Organization (WHO) response criteria. PFS per WHO criteria achieved a HR of 1.02. Oral selinexor demonstrated an expected and manageable safety profile, primarily with nausea, fatigue, anorexia and weight loss, with low levels of Grade 3/4 cytopenias, and no new or unexpected safety signals identified. The majority of treatment-related adverse events (AEs) were low grade and reversible with dose modifications and/or standard supportive care. These data from the Phase 2 portion of the SEAL study, which is now complete, demonstrate that treatment with selinexor improves PFS (RECIST v1.1) and supports the currently ongoing Phase 3 portion of the study using RECIST v1.1 response criteria [only], and for which top-line data are expected by the end of 2019.

Dr. Gounder stated, "Extending PFS in patients with recurrent, unresectable DDLS is an important clinical goal and these data highlight that oral selinexor continues to demonstrate an expected and manageable safety profile, along with the ability to prolong PFS. We are pleased to share these data with the medical community at ASCO (Free ASCO Whitepaper) this year and look forward to further elucidating selinexor’s efficacy and safety in the already ongoing Phase 3 portion of the SEAL study."

Selinexor in Combination with Immunotherapy or Standard of Care Agents in Other Hematologic and Solid Tumor Malignancies

In the poster presentation titled, "Phase 1b study of selinexor, a first in class selective inhibitor of nuclear export (SINE) compound, in combination with doxorubicin in patients (pts) with locally advanced or metastatic soft tissue sarcoma (STS)," (Abstract #11562) Eoghan Ruadh Malone, MB BCh, BAO, BA, MSc, MRCPI, Princess Margaret Cancer Centre, presented results from an investigator-sponsored Phase 1b clinical study evaluating selinexor in combination with doxorubicin in 17 patients with locally advanced or metastatic STS. Disease subtypes included leiomyosarcoma (n=6), undifferentiated pleomorphic sarcoma (n=3), liposarcoma (n=2), malignant peripheral nerve sheath tumor (n=3) and other sarcomas (n=3). Preliminary data from this study show that the combination of selinexor plus doxorubicin has a manageable tolerability profile, along with early signals of anti-tumor activity, including partial responses (n=3). Median time on treatment is 20 weeks. Enrollment in the study is ongoing.

In the poster presentation titled, "Phase 1 study of selinexor plus mitoxantrone, etoposide, and cytarabine in acute myeloid leukemia," (Abstract #7048) Bhavana Bhatnagar, DO, Ohio State University Comprehensive Cancer Center, presented results from an investigator-sponsored Phase 1 clinical study evaluating selinexor in combination with mitoxantrone, etoposide and cytarabine (MEC) in patients with relapsed or refractory AML. Of the 23 evaluable patients, ten responded for an overall response rate of 44%, including six patients (26%) achieving complete remission (CR), two patients (9%) achieving CR with incomplete count recovery (CRi), and two patients (9%) achieving a morphologic leukemia-free state (MLFS). The tolerability of this combination regimen was similar to cytotoxic chemotherapy alone. The most common Grade ≥3 adverse events were febrile neutropenia (48%), catheter related infection (26%), diarrhea (26%), hyponatremia (22%), sepsis (22%), fatigue (13%), hyperglycemia (13%), and hypotension (13%). The RP2D of selinexor in in this combination regimen was established to be 60mg twice weekly. Six responders proceeded to allogeneic stem cell transplantation without evidence of AML at the time of transplant.

In the poster presentation titled, "Profiling the immune checkpoint pathway in acute myeloid leukemia," (Abstract #7015) Paola Dama, PhD, University of Chicago, presented results from an investigator-sponsored study assessing the expression of immune checkpoint biomarkers in AML patients treated with the combination of selinexor, high-dose cytarabine (HiDAC) and mitoxantrone. Data from this study demonstrated high level expression of Gal9 in CD34- cells at diagnosis in patients who failed induction chemotherapy, compared to those in complete remission. There was no difference in PD-L1 expression between the two patient groups. Increased expression of Tim 3 on CD4 and CD8 T cells and high PD-1 in peripheral CD4+ T cell were observed at disease remission suggesting an exhausted immune status at the time of disease remission on the selinexor + HiDAC + mitoxantrone combination, which the researchers believe could be targeted with the addition of checkpoint inhibitors.

About Selinexor

Selinexor (KPT-330) 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. To date, over 2,400 patients have been treated with selinexor. In April 2018, Karyopharm reported positive top-line data from the Phase 2b STORM study evaluating selinexor in combination with low-dose dexamethasone in patients with penta-refractory multiple myeloma. Selinexor has been granted Orphan Drug Designation in multiple myeloma and Fast Track designation for the patient population evaluated in the STORM study. Karyopharm plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) during the second half of 2018, with a request for accelerated approval for oral selinexor as a new treatment for patients with penta-refractory multiple myeloma. The Company also plans to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in early 2019 with a request for conditional approval. 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) and as a potential backbone therapy in combination with approved therapies (STOMP), and in diffuse large B-cell lymphoma (SADAL), 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 one or more 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.

"Pfizer is extremely proud to offer expanded biologic treatment options for patients by bringing more affordable, life changing biosimilar medicines to market, and today’s positive recommendation from the CHMP marks one more step forward. TRAZIMERA has the potential to help many patients with HER2 overexpressing cancers across Europe and, if approved, would help address the evolving needs of healthcare systems, physicians, payers and patients, "said Amrit Ray, MD, MBA, Global President, Research & Development, Pfizer Essential Health.

The regulatory submission is supported with a comprehensive data package and totality of evidence demonstrating a high degree of similarity to the originator product. This includes results from the primary REFLECTIONS B327-02 clinical comparative study, which demonstrated clinical equivalence and found no clinically meaningful differences between TRAZIMERA and Herceptin in patients with first line HER2 overexpressing metastatic breast cancer. As part of the REFLECTIONS clinical trial program for the proposed biosimilar trastuzumab, TRAZIMERA has been studied in nearly 500 patients and across more than 20 countries to date.2,3,4

"Many patients with breast and gastric cancers have an HER2 overexpression, which can correlate with poor outcomes and aggressive disease," said Dr. Mark Pegram, associate director for clinical research at the Stanford Comprehensive Cancer Institute, and director of the Breast Oncology Program at the Stanford Women’s Cancer Center.5,6 "With the availability of biosimilars like TRAZIMERA in Europe, oncologists will have additional treatment options to choose from, which potentially helps our patients have greater access to these medicines."

TRAZIMERA is Pfizer’s fourth7,8,9 biosimilar and first therapeutic oncology biosimilar to receive a positive CHMP opinion from the EMA. Pfizer’s biosimilars pipeline is progressing and consists of 11 distinct Pfizer and legacy Hospira biosimilar molecules in various stages of development.

On June 1, 2018 AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, reported findings from an interim analysis of the Phase 3 iNNOVATE (PCYC-1127) study evaluating IMBRUVICA (ibrutinib) plus RITUXAN (rituximab) in previously untreated and relapsed/refractory patients with Waldenström’s macroglobulinemia (WM), a rare type of non-Hodgkin’s lymphoma (NHL) (Press release, AbbVie, JUN 1, 2018, View Source [SID1234527031]). At a median follow up of 26.5 months, the study successfully met its primary endpoint, demonstrating a significant improvement in progression-free survival (PFS) with ibrutinib plus rituximab compared to rituximab alone (30 month PFS rates were 82 percent versus 28 percent, respectively). Patients taking ibrutinib plus rituximab also experienced an 80 percent reduction in relative risk of disease progression or death than those only treated with rituximab (hazard ratio, 0.20; confidence interval: 0.11-0.38, P <0.0001). Additionally, the data found that the combination with ibrutinib provided reductions in infusion reactions associated with rituximab and immunoglobin M (IgM) flare.1

These data were presented today in an oral presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago (abstract #8003) and were simultaneously published in The New England Journal of Medicine. The data were also selected for the 2018 Best of ASCO (Free ASCO Whitepaper) Meetings. With the support of these positive findings, a supplemental New Drug Application (sNDA) to expand the use of IMBRUVICA as a combination therapy in WM was submitted to the U.S. Food and Drug Administration (FDA) for review. The Independent Data Monitoring Committee (IDMC) in late 2017 recommended unblinding iNNOVATE based on these positive findings.

"The iNNOVATE study provides further evidence of the potential clinical benefit of IMBRUVICA-based combination therapy in patients with Waldenström’s macroglobulinemia," said Thorsten Graef, M.D., Ph.D., Head of Clinical Development at Pharmacyclics LLC, an AbbVie company. "The data from this chemotherapy-free combination regimen suggests that patients with Waldenström’s macroglobulinemia, including those who are newly diagnosed, could have another beneficial therapeutic option in the future."

WM is a rare and incurable form of NHL with limited treatment options. There are about 2,800 new cases of WM in the U.S. each year.2 In January 2015, IMBRUVICA received FDA approval for all lines of treatment in WM and is the first and only FDA-approved therapy specifically indicated for this disease. IMBRUVICA has been available in the U.S. since 2013 and is FDA-approved for use in five B-cell blood cancers, as well as previously-treated chronic graft-versus-host disease. IMBRUVICA is a first-in-class Bruton’s tyrosine kinase (BTK) inhibitor jointly developed and commercialized by Pharmacyclics LLC, an AbbVie company, and Janssen Biotech, Inc.

"The iNNOVATE trial broadens our understanding about how to treat patients with WM, including those with certain subtypes or genomic abnormalities," said Dr. Meletios A. Dimopoulos, Professor and Chairman of the Department of Clinical Therapeutics, National and Kapodistrian University of Athens School of Medicine, Athens, Greece and lead investigator of the iNNOVATE study.* "As a clinician, I’m hopeful that the data from iNNOVATE could potentially lead to a new option for treating this rare and incurable disease."

Abstract #8001: Randomized phase 3 trial of ibrutinib/rituximab vs placebo/rituximab in Waldenström’s Macroglobulinemia
Oral presentation: Friday, June 1, 3:45pm CDT

In the iNNOVATE study, PFS occurred at a higher rate in patients treated with ibrutinib plus rituximab compared to rituximab alone, with PFS rates of 82% versus 28% at 30 months, respectively. Notably, ibrutinib plus rituximab exhibited longer duration of PFS in all relevant patient subgroups, including treatment-naïve, relapsed, and in patients with MYD88L265P and CXCR4WHIM mutations, versus rituximab. Patients taking ibrutinib plus rituximab also experienced an 80 percent reduction in relative risk of disease progression or death than those only treated with rituximab (median PFS, not reached [NR] vs 20.3 months; HR, 0.20; CI: 0.11-0.38, P <0.0001).

iNNOVATE is a Pharmacyclics-sponsored, placebo-controlled, double-blind, Phase 3 study, which evaluated relapsed/refractory and treatment-naïve WM patients (n=150) who were randomized to receive intravenous rituximab 375 mg/m2 once weekly for four consecutive weeks, followed by a second once-weekly for four consecutive weeks rituximab course after a three-month interval. All patients received either ibrutinib 420 mg or placebo once daily continuously until criteria for permanent discontinuation were met. The IRC-determined primary endpoint was PFS, with secondary objectives including overall response rate, hematological improvement measured by hemoglobin, time-to-next treatment (TTnT), overall survival (OS), and number of participants with adverse events (AEs) as a measure of safety and tolerability within each treatment arm.

Overall response rates and major response rates were significantly higher for ibrutinib plus rituximab versus rituximab (92% vs 47%; 72% vs 32% [both P <0.0001]). In addition, there was also an improvement in hemoglobin seen in patients treated with the combination versus rituximab (73% vs 41%, P <0.0001).

Of the patients on ibrutinib plus rituximab, 75% continued on treatment. Median TTnT was NR for ibrutinib plus rituximab and 18 months for rituximab (HR, 0.096; P <0.0001). The 30-month OS rates were 94% versus 92% in the two arms.

At the median time on treatment (ibrutinib plus rituximab, 25.8 months; rituximab plus placebo, 15.5 months,), grade 3 or higher treatment-emergent AEs occurred in 60% of patients treated with ibrutinib plus rituximab, versus 61% of patients treated with rituximab. Serious AEs occurred in 43% versus 33% of patients on ibrutinib plus rituximab vs rituximab. No fatal AEs occurred with ibrutinib plus rituximab and 3 with rituximab. Meaningful reductions in any grade IgM flare (8% vs 47%) and grade 3 or higher infusion reactions were observed (1% vs 16%) with ibrutinib plus rituximab.

About IMBRUVICA
IMBRUVICA (ibrutinib) is a first-in-class, oral, once-daily therapy that mainly works by blocking a protein called Bruton’s tyrosine kinase (BTK). BTK is a key signaling molecule in the B-cell receptor signaling complex that plays an important role in the survival and spread of malignant B cells as well as other serious, debilitating conditions.3 IMBRUVICA blocks signals that tell malignant B cells to multiply and spread uncontrollably.

IMBRUVICA is FDA-approved in six distinct patient populations: chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Waldenström’s macroglobulinemia (WM), along with previously-treated mantle cell lymphoma (MCL), previously-treated marginal zone lymphoma (MZL) and previously-treated chronic graft-versus-host disease (cGVHD).4

IMBRUVICA was first approved for adult patients with MCL who have received at least one prior therapy in November 2013.
Soon after, IMBRUVICA was initially approved in adult CLL patients who have received at least one prior therapy in February 2014. By July 2014, the therapy received approval for adult CLL patients with 17p deletion, and by March 2016, the therapy was approved as a frontline CLL treatment.
IMBRUVICA was approved for adult patients with WM in January 2015.
In May 2016, IMBRUVICA was approved in combination with bendamustine and rituximab (BR) for adult patients with previously treated CLL/SLL.
In January 2017, IMBRUVICA was approved for adult patients with MZL who require systemic therapy and have received at least one prior anti-CD20-based therapy.
In August 2017, IMBRUVICA was approved for adult patients with cGVHD that failed to respond to one or more lines of systemic therapy.
Accelerated approval was granted for the MCL and MZL indications based on overall response rate. Continued approval for MCL and MZL may be contingent upon verification and description of clinical benefit in confirmatory trials.

IMBRUVICA has been granted four Breakthrough Therapy Designations from the U.S. FDA. This designation is intended to expedite the development and review of a potential new drug for serious or life-threatening diseases.5 IMBRUVICA was one of the first medicines to receive FDA approval via the new Breakthrough Therapy Designation pathway.

IMBRUVICA is being studied alone and in combination with other treatments in several blood and solid tumor cancers and other serious illnesses. IMBRUVICA has one of the most robust clinical oncology development programs for a single molecule in the industry, with more than 130 ongoing clinical trials. There are approximately 30 ongoing company-sponsored trials, 14 of which are in Phase 3, and more than 100 investigator-sponsored trials and external collaborations that are active around the world. To date, 100,000 patients around the world have been treated with IMBRUVICA in clinical practice and clinical trials.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Hemorrhage: Fatal bleeding events have occurred in patients treated with IMBRUVICA. Grade 3 or higher bleeding events (intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and post-procedural hemorrhage) have occurred in up to 6% of patients. Bleeding events of any grade, including bruising and petechiae, occurred in approximately half of patients treated with IMBRUVICA.
The mechanism for the bleeding events is not well understood.

IMBRUVICA may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies and patients should be monitored for signs of bleeding.

Consider the benefit-risk of withholding IMBRUVICA for at least 3 to 7 days pre and post-surgery depending upon the type of surgery and the risk of bleeding.

Infections: Fatal and non-fatal infections (including bacterial, viral, or fungal) have occurred with IMBRUVICA therapy. Grade 3 or greater infections occurred in 14% to 29% of patients. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with IMBRUVICA. Consider prophylaxis according to standard of care in patients who are at increased risk for opportunistic infections.

Monitor and evaluate patients for fever and infections and treat appropriately.

Cytopenias: Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (range, 13 to 29%), thrombocytopenia (range, 5 to 17%), and anemia (range, 0 to 13%) based on laboratory measurements occurred in patients with B-cell malignancies treated with single agent IMBRUVICA.

Monitor complete blood counts monthly.

Cardiac Arrhythmias: Fatal and serious cardiac arrhythmias have occurred with IMBRUVICA therapy. Grade 3 or greater ventricular tachyarrhythmias occurred in 0 to 1% of patients, and Grade 3 or greater atrial fibrillation and atrial flutter occurred in 0 to 6% of patients. These events have occurred particularly in patients with cardiac risk factors, hypertension, acute infections, and a previous history of cardiac arrhythmias.

Periodically monitor patients clinically for cardiac arrhythmias. Obtain an ECG for patients who develop arrhythmic symptoms (e.g., palpitations, lightheadedness, syncope, chest pain) or new onset dyspnea. Manage cardiac arrhythmias appropriately, and if it persists, consider the risks and benefits of IMBRUVICA treatment and follow dose modification guidelines.

Hypertension: Hypertension (range, 6 to 17%) has occurred in patients treated with IMBRUVICA with a median time to onset of 4.6 months (range, 0.03 to 22 months). Monitor patients for new onset hypertension or hypertension that is not adequately controlled after starting IMBRUVICA.

Adjust existing anti-hypertensive medications and/or initiate anti-hypertensive treatment as appropriate.

Second Primary Malignancies: Other malignancies (range, 3 to 16%) including non-skin carcinomas (range, 1 to 4%) have occurred in patients treated with IMBRUVICA. The most frequent second primary malignancy was non-melanoma skin cancer (range, 2 to 13%).

Tumor Lysis Syndrome: Tumor lysis syndrome has been infrequently reported with IMBRUVICA therapy. Assess the baseline risk (e.g., high tumor burden) and take appropriate precautions.

Monitor patients closely and treat as appropriate.

Embryo-Fetal Toxicity: Based on findings in animals, IMBRUVICA can cause fetal harm when administered to a pregnant woman. Advise women to avoid becoming pregnant while taking IMBRUVICA and for 1 month after cessation of therapy. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Advise men to avoid fathering a child during the same time period.

ADVERSE REACTIONS

B-cell malignancies: The most common adverse reactions (≥20%) in patients with B-cell malignancies (MCL, CLL/SLL, WM and MZL) were thrombocytopenia (62%)*, neutropenia (61%)*, diarrhea (43%), anemia (41%)*, musculoskeletal pain (30%), bruising (30%), rash (30%), fatigue (29%), nausea (29%), hemorrhage (22%), and pyrexia (21%).

The most common Grade 3 or 4 adverse reactions (≥5%) in patients with B-cell malignancies (MCL, CLL/SLL, WM and MZL) were neutropenia (39%)*, thrombocytopenia (16%)*, and pneumonia (10%).

Approximately 6% (CLL/SLL), 14% (MCL), 11% (WM) and 10% (MZL) of patients had a dose reduction due to adverse reactions. Approximately 4%-10% (CLL/SLL), 9% (MCL), and 9 % (WM [6%] and MZL [13%]) of patients discontinued due to adverse reactions.

cGVHD: The most common adverse reactions (≥20%) in patients with cGVHD were fatigue (57%), bruising (40%), diarrhea (36%), thrombocytopenia (33%)*, stomatitis (29%), muscle spasms (29%), nausea (26%), hemorrhage (26%), anemia (24%)*, and pneumonia (21%).

The most common Grade 3 or 4 adverse reactions (≥5%) reported in patients with cGVHD were fatigue (12%), diarrhea (10%), neutropenia (10%)*, pneumonia (10%), sepsis (10%), hypokalemia (7%), headache (5%), musculoskeletal pain (5%), and pyrexia (5%).

Twenty-four percent of patients receiving IMBRUVICA in the cGVHD trial discontinued treatment due to adverse reactions. Adverse reactions leading to dose reduction occurred in 26% of patients.

*Treatment-emergent decreases (all grades) were based on laboratory measurements and adverse reactions.

DRUG INTERACTIONS

CYP3A Inhibitors: Dose adjustment may be recommended.

CYP3A Inducers: Avoid coadministration with strong CYP3A inducers.

SPECIFIC POPULATIONS
Hepatic Impairment (based on Child-Pugh criteria): Avoid use of IMBRUVICA in patients with severe baseline hepatic impairment. In patients with mild or moderate impairment, reduce IMBRUVICA dose.
