- Follows Positive Interim Analysis of Phase 2 Results -
- First of Three Randomized Studies Sponsored by
Advancement into the Phase 3 extension follows an interim analysis of results from 50 patients who received the ganetespib-cytarabine combination in the Phase 2 portion of the trial. The primary efficacy outcome in Phase 2 was rate of complete response. Per protocol, the Phase 3 extension will include an interim futility analysis and enroll approximately 200 patients in the ganetespib-cytarabine and the cytarabine alone arms, for a total of approximately 400 patients. The primary efficacy endpoint for the Phase 3 extension will include overall survival. The Company is currently in discussion with study investigators, and anticipates providing additional details, including the timing of study milestones, as they become formalized.
The AML LI-1 trial is the first of three multicenter, randomized studies
supported by the
“AML LI-1’s ‘pick-the-winner’ trial design is intended to rapidly assess
new therapeutics with the potential to improve outcomes in very
difficult to treat patients with AML and MDS,” said Professor
“Ganetespib’s progress in the AML LI-1 study underscores the potential
of Hsp90 inhibition across a broad range of cancers,” said Dr.
About AML and MDS
AML is a rapidly progressing hematologic cancer characterized by
uncontrolled proliferation of immature blast cells in the bone marrow.
MDS is a hematopoietic stem cell neoplasm characterized by disordered and ineffective hematopoiesis which results in irreversible decline in the number and quality of blood-forming cells. Patients often develop severe anemia requiring frequent blood transfusions. In most cases progressive bone marrow failure results in neutropenia and thrombocytopenia, and in about one third of patients the disease progresses into AML, usually within a few years.
Ganetespib, an investigational drug candidate, is a selective inhibitor of heat shock protein 90 (Hsp90), a molecular chaperone which controls the folding and activation of a number of client proteins that drive tumor development and progression. Many solid and hematologic tumors are dependent on Hsp90 client proteins including proteins involved in “oncogene addiction” (ALK, HER2, mutant BRAF and EGFR, androgen receptor, estrogen receptor, and JAK2); proteins involved in resistance to chemotherapy and radiation therapy (ATR, BCL2, BRCA1/2, CDK1/4, CHK1, survivin, and WEE1); proteins involved in angiogenesis (HIF-1alpha, VEGFR, PDFGR, and VEGF); and proteins involved in metastasis (MET, RAF, AKT, MMPs, HIF-1alpha, and IGF-1R). In preclinical models, inhibition of Hsp90 by ganetespib results in the inactivation, destabilization, and eventual degradation of these cancer-promoting proteins. Ganetespib is being evaluated in trials in lung cancer, breast cancer, and other tumor types. The most common adverse event seen to date has been transient, mild or moderate diarrhea, which has been manageable with standard supportive care. Information on these trials can be found at www.clinicaltrials.gov. Ganetespib has received Fast Track designation from FDA for second-line treatment of non-small cell lung adenocarcinoma in combination with docetaxel.
