HOOKIPA (HOOK), Merck Collaborate to Treat Head & Neck Cancers


HOOKIPA (HOOK Quick QuoteHOOK ) announced that it has entered into a clinical collaboration and supply agreement with Merck (MRK Quick QuoteMRK ) to evaluate the former’s novel arenaviral program, HB-200, in combination with the latter’s PD-L1 inhibitor Keytruda as a first-line treatment for advanced head and neck squamous cell carcinoma (“HNSCC”).

The collaboration between the two companies is based on positive data from the ongoing HB-200 phase I/IIstudy evaluating the HB-200 program for the treatment of human papillomavirus 16-positive (“HPV16+”) cancers in heavily pre-treated patients. Data from the phase I study demonstrated that the HB-200 therapy has a favorable safety profile, both as a monotherapy and in combination with other checkpoint inhibitors.

Earlier this year, HOOPIKA also presented data from the ongoing HB-200 phase I/IIstudy at ASCO 2021. Data from the study demonstrated that HB-201 achieved an overall response rate of 18% in heavily pre-treated patients, while data from pre-clinical studies indicated that the HB-201/HB-202 therapy achieved a disease control rate of 100%.

A phase II study evaluating a combination of HB-200 and Keytruda in HNSCC is expected to begin in 2022. The company is also planning to start additional phase II expansion cohorts in first-quarter 2022.

In the year so far, HOOKIPA’s stock price has plunged 43.4% in comparison with the industry’s 1.2% decline.
