- Durable Stable Disease Observed for Patients with Non-enhancing Low Grade Glioma and Chondrosarcoma Patients; 42% of Glioma Patients Still on Treatment -
- AG-120 Well-tolerated in Pre-Treated Populations -
- Potential for Centralized Volumetric Assessments to Shape Future Development in Glioma -
CAMBRIDGE, Mass., Nov. 18, 2016 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (Nasdaq:AGIO), a leader in the fields of cancer metabolism and rare genetic metabolic disorders, today announced the first data from the dose expansion cohorts of the Phase 1 study evaluating single agent AG-120 in isocitrate dehydrogenase-1 (IDH1) mutant positive glioma and chondrosarcoma. The glioma data were presented today at the Society for Neuro-Oncology (SNO) Annual Meeting in Scottsdale, AZ and the chondrosarcoma data were presented last week at the annual meeting of the Connective Tissue Oncology Society (CTOS) in Lisbon, Portugal.
“Glioma and chondrosarcomas are extremely difficult-to-treat diseases where patients are in need of new therapies,” said Chris Bowden, M.D., chief medical officer at Agios. “These Phase 1 dose expansion data are encouraging, as they continue to demonstrate a well-tolerated safety profile for AG-120 at a fixed daily dose of 500 mg. The prolonged stable disease in both patient populations is encouraging in light of AG-120’s unique differentiation mechanism of action. In addition, our initial experience utilizing centralized volumetric assessments in patients with glioma has been informative, and along with our ongoing AG-881 Phase 1 trial, will help determine the next steps in clinical development.”
“In glioma, AG-120 has the potential to help a large number of patients with IDH1 mutations,” said Ingo Mellinghoff, M.D., Memorial Sloan Kettering Cancer Center, an investigator for the study. “The SNO presentation is the first look at data for AG-120 in a defined cohort of glioma patients where we evaluated the potential for volumetric analyses to improve our understanding of the response patterns beyond the conventional bi-dimensional methods. This methodology could be instrumental in developing more effective, targeted therapies for patients with this disease.”
The Phase 1 trial is assessing the safety and tolerability of AG-120 in advanced solid tumors, including glioma, intrahepatic cholangiocarcinoma (IHCC) and chondrosarcomas that harbor an IDH1 mutation. The dose-escalation phase was followed by four expansion cohorts in the following patient groups.
Enrollment is now complete for the dose escalation and expansion cohorts.
Glioma Expansion Data Presented at SNO Annual Meeting
As of the August 1, 2016 data cut off, 66 patients have been treated with single agent AG-120, and 28 patients (42%) remain on treatment.
A safety analysis conducted for all 66 treated patients as of the data cut-off demonstrated that AG-120 was well-tolerated with a favorable safety profile in glioma patients.
Efficacy data from 65 response-evaluable patients as of the data cut-off showed:
Chondrosarcoma Expansion Data Presented at CTOS Annual Meeting
Agios also analyzed data from 21 chondrosarcoma patients as of September 23, 2016 in the dose escalation (n=12) and expansion cohorts (n=9) and 7 remain on treatment.
Glioma presents in varying degrees of tumor aggressiveness, ranging from slower growing (low grade glioma) to rapidly progressing (high grade glioma-Glioblastoma Multiforme). Common symptoms include seizures, memory disturbance, sensory impairment neurologic deficits and seizures. The long-term prognosis is poor with a five-year survival rate of 33 percent. Median survival is 12-15 months for glioblastoma and 2-5 years for anaplastic glioma. IDH1 mutations are highly prevalent, accounting for approximately 68-74 percent of low grade glioma and secondary glioblastoma.
Chondrosarcoma is a heterogeneous group of cancers that arise from cartilage in the bone and joint. It is the most common type of bone cancer with 700-1,000 people diagnosed per year in the U.S. IDH1/2 mutations occur in approximately 46-63 percent of central chondrosarcomas. The prognosis is based on disease burden – for localized disease, there is curative potential with surgery, but metastatic disease has a low five-year survival rate. Radiation is not effective, and chemotherapy is of limited benefit. Treatment for metastatic disease is mainly palliative.
Agios Pharmaceuticals is focused on discovering and developing novel drugs to treat cancer and rare genetic disorders of metabolism through scientific leadership in the field of cellular metabolism. In addition to an active research and discovery pipeline across both therapeutic areas, Agios has multiple first-in-class investigational medicines in cancer metabolism and rare genetic disorders of metabolism in clinical and/or preclinical development. All Agios programs focus on genetically identified patient populations, leveraging the company's knowledge of metabolism, biology and genomics.
