"We are excited by these promising data to be presented at EHA, which continue to demonstrate the vast potential of selinexor across hematologic malignancies," said
The following abstracts describe the potential role of selinexor, Karyopharm's first-in-class, oral Selective Inhibitor of Nuclear Export / SINE™ compound in DLBCL and advanced AML. These data will be further updated in the presentations at EHA:
- An oral presentation with updated data from an ongoing Phase 1 clinical trial demonstrating that objective responses achieved with selinexor in this trial are durable and correlate with improved overall survival and progression free survival compared with patients who achieved stable or progressive disease, suggesting that these responses are associated with clinical benefit.
Title: Patients with Heavily Pretreated Diffuse Large B-Cell Lymphoma (DLBCL) who Respond to Oral Selinexor Therapy Show Prolonged Survival: Updated Phase 1 Results
|Session:||Optimization and innovation in treating aggressive lymphomas|
- A late-breaking poster presentation of preliminary data from an ongoing Phase 2 clinical trial demonstrating that selinexor in combination with standard doses of Ara-C and idarubicin is a potentially effective strategy for treating patients with AML that was relapsed or refractory after at least one line of chemotherapy, without unexpected toxicities. An overall response rate of 53% (eight) was achieved based on fifteen evaluable patients and 67% (six) of those patients went on to receive either stem cell transplant or donor lymphocyte infusion. This represents the first presentation of clinical results of selinexor in combination with chemotherapy.
Title: Preliminary Phase II Results of Ara-C And Idarubicin in Combination with Selective Inhibitor of Nuclear Export (Sine) Compound Selinexor (KPT-330) in Patients with Relapsed or Refractory AML
|Session:||Acute myeloid leukemia - Clinical 4|
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, which subsequently reinitiates and amplifies their tumor suppressor function. This is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. Over 900 patients have been treated with selinexor in company- and investigator-sponsored Phase 1 and Phase 2 clinical trials in advanced hematologic malignancies and solid tumors. Karyopharm has initiated three registration-directed clinical trials of single-agent selinexor, including one in older patients with acute myeloid leukemia (SOPRA), one in patients with Richter's transformation (SIRRT) and one in patients with diffuse large B-cell lymphoma (SADAL). Karyopharm plans to initiate a single-arm trial of selinexor in multiple myeloma in the first half of 2015 that is also intended to be registration-directed. In solid tumors, Karyopharm plans to initiate a registration-directed trial of selinexor to treat liposarcoma during the second half of 2015. Additional Phase 1 and Phase 2 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 the company's clinical development priorities for selinexor. The latest clinical trial information for selinexor is available at www.clinicaltrials.gov.
Karyopharm Therapeutics Inc. (Nasdaq:KPTI) is a clinical-stage pharmaceutical company focused on the discovery and development of novel first-in-class drugs directed against nuclear transport targets for the treatment of cancer and other major diseases. Karyopharm's SINE™ compounds function by binding with and inhibiting the nuclear export protein XPO1 (or CRM1). In addition to single-agent activity against a variety of different human cancers, SINE™ compounds have also shown biological activity in models of cancer, inflammation, autoimmune disease, certain viruses, and wound-healing.
