Prima (PBMD) Reports Favorable Initial Melanoma Study Data

MRK VNDA

Prima Biomed Ltd. announced interim data from a phase I study of the TACTI-mel (Two ACTive Immunotherapeutics in melanoma) program on its most advanced pipeline candidate IMP321 (based on the LAG-3 immune control mechanism), for the treatment of patients with unresectable or metastatic melanoma.

The company’s shares surged 7.4% after the news. Prima’s year-to-date share price movement shows that the company has underperformed the Zacks classified Medical-Biomedical/Genetics industry. Specifically, the stock plunged almost 34.2% during this period, steeper than the industry’s declined of 26.1%.

The study evaluated IMP321, in combination with Merck & Co., Inc.’s (MRK - Free Report) PD-1 checkpoint inhibitor Keytruda, in patients with unresectable or metastatic melanoma who had suboptimal or no responses to Keytruda.

The Database Safety Monitoring Board (DSMB) confirmed that IMP321, in combination with Keytruda, was safe and well tolerated when dosed at 1 mg. Further, the DSMB approved the continuation of the dose escalation to the next level of 6 mg.

The company expects to read out additional data in terms of safety and activity throughout 2017.

IMP321 is also being evaluated, in combination with Celgene Corporation’s Abraxane, in a phase IIb chemo-immunotherapy study AIPAC (Active Immunotherapy PAClitaxel) for the treatment of metastatic breast cancer.

The company noted that many large pharmaceutical partners are developing LAG-3 products including antibodies for immune response modulation in autoimmunity and cancer.

Prima currently carries a Zacks Rank #3 (Hold).
