Geron : Phase 2 Trial of GRN1005 in Brain Metastases From Lung Cancer

Geron
December 22, 2011 - Geron Corporation (Nasdaq: GERN) announced the initiation of GRABM-L (GRN1005 Against Brain Metastases - Lung cancer), a Phase 2 clinical trial to evaluate GRN1005 in patients with brain metastases arising from non-small cell lung cancer (NSCLC). GRN1005 is the company's lead LRP-directed peptide-drug conjugate (LRP-directed PDC) and consists of the cytotoxic drug paclitaxel linked to a peptide (Angiopep-2) that targets the LRP receptor to cross the blood-brain barrier (BBB) and to target tumors in the brain.

"With the treatment of the first patient in the GRABM-L study, we have initiated both of the planned Phase 2 clinical trials of GRN1005 in patients with cancer metastases in the brain, a significant unmet medical need for which there are currently no approved drug therapies," said Stephen M. Kelsey, M.D., Geron's Executive Vice President, Head of R&D and Chief Medical Officer. "We have been encouraged by the preliminary evidence of anti-tumor activity against brain metastases observed in the Phase 1 study of GRN1005, and we hope to confirm these results in our Phase 2 trials."

Phase 2 Clinical Trial Design (GRABM-L) 

The purpose of the Phase 2 study is to assess the efficacy, safety and tolerability of GRN1005 in patients with brain metastases from NSCLC. The trial plans to enroll 50 patients.

GRN1005 will be administered at a dose of 650 mg/m2 by intravenous (IV) infusion every three weeks. The primary efficacy endpoint for the trial is overall (intra-cranial and extra-cranial disease) objective response rate. Key secondary endpoints include duration of overall objective response, duration of overall progression-free survival and six month overall survival....Geron's Press Release -
