Biopharma's Anti-PD-L1 Antibody Advances in Two Oncologic Indications
Research Report

Share on Stocktwits


Checkpoint Therapeutics' "cosibelimab represents a competitive asset on both efficacy and safety with an expected added advantage of lower net price," an H.C. Wainwright & Co. report noted.

Checkpoint Therapeutics Inc. (CKPT:NASDAQ) is in the news with two noteworthy developments. The CONTERNO Phase 3 study, evaluating its lead drug candidate cosibelimab in non-small cell lung cancer, launched, according to a Dec. 8 research note compiled by H.C. Wainwright & Co. analyst Joseph Pantginis. Also, a potential stock moving catalyst is about to happen any day now, in the release of topline data from the trial of cosibelimab in metastatic cutaneous squamous cell carcinoma.

The immuno-oncology and targeted oncology firm has a share price now of around $2.92, and H.C. Wainwright has a $17 per share target price on Checkpoint Therapeutics. The difference suggest a substantial potential return for investors.

Pantginis reiterated the key details of CONTERNO and noted its design is like that for Keytruda's KEYNOTE-189. For the open label and randomized CONTERNO trial, about 560 patients, with previously untreated stage IV non-small cell lung cancer without EGFR or ALK mutations, will be enrolled. Enrollment is expected to take about 15 months. Participants will be recruited from 75 sites, including ones in Russia, Ukraine, Georgia, Belarus, New Zealand, Thailand, Malaysia, South Africa, Brazil, and Peru.

CONTERNO patients will be randomized on a 2:1 basis to receive cosibelimab plus pemetrexed plus the investigator's choice of platinum chemotherapy (either carboplatin or cisplatin) or only pemetrexed plus platinum. Cosibelimab is an anti-PD-L1 antibody. The primary endpoint is overall survival. Secondary endpoints include safety, progression-free survival, and overall response rate.

Pantginis noted that "CONTERNO looks to launch off of the data previously announced from the non-small cell lung cancer cohort in the Phase 1, which compares favorably to the prior established data with Keytruda and Tecentriq in patients with high PD-L1 expression."

As for Checkpoint Therapeutics' upcoming data readout, it will happen for the registrational study of cosibelimab in squamous cell carcinoma by year-end.

Subsequently, next year, the immuno-oncology firm plans to file a biologics license application in the U.S. and a marketing authorization application in Europe, both for cosibelimab. H.C. Wainwright expects both to be approved, Pantginis indicated.

"We believe cosibelimab represents a competitive asset on both efficacy and safety with an expected added advantage of lower net price," the analyst wrote. "Importantly, we continue to project increasing levels of business development discussions around the asset as we see a continuing appetite for differentiated immuno-oncology drugs, and deals continue to be consummated."

H.C. Wainwright's rating on Checkpoint Therapeutics is Buy.
