PharmAbcine Announces Acceptance of Phase Ib Olinvacimab and Pembrolizuamb Combination Trial in rGBM Patients Abstract at the 2020 ASCO Annual Meeting

PharmAbcine Inc. (KOSDAQ: 208340) announced today that the abstract summarizing interim data on its phase Ib trial of olinvacimab in combination with Merck’s anti-PD-1 antibody Keytruda® for recurrent glioblastoma multiforme (rGBM) patients has been accepted at the 2020 American Society of Clinical Oncology (ASCO) Annual Meeting.   

Phase Ib study is to evaluate the safety of the combination therapy of two agents for rGBM patients and to explore appropriate clinical dose levels of the two agents as in a combination regimen. During the study, 200 mg of Keytruda® was administered to patients every three weeks while 12 or 16 mg/kg of olinvaciamb was administered on a weekly basis. From the phase Ib study, there was no DLT (dose limiting toxicity) observed, and among 9 patients, 4 patients had SD (stable disease) and 5 patients experienced disease progression (PD).

rGBM is a rare tumor and there are only a few treatment options available to date. It is known to have the worst prognosis among any other types of cancers/tumors and the life expectancy of rGBM patients is less than 4 months upon diagnosis. There have been multiple clinical trials using immuno-oncology drugs to treat rGBM but the promising results have not been reported yet.  

Previously Olinvacimab from its phase IIa clinical study in rGBM patients ascertained its significant improvement of brain edema and shrinkage of tumor. Now its use is being investigated in a phase II study for Avastin-refractory rGBM patients in US and Australia.

An ASCO annual meeting is a global conference, annually accommodating 40,000 people from 76 different countries.
