HOOKIPA to Present Complete HB-200 Phase 1 Results and Recommended Phase 2 Dose for HB-202/HB-201 for the Treatment of Advanced HPV16+ Cancers at ASCO
NEW YORK and VIENNA, Austria, May 26, 2022 (GLOBE NEWSWIRE) -- HOOKIPA Pharma Inc. (NASDAQ: HOOK, ‘HOOKIPA’), a company developing a new class of immunotherapeutics based on its proprietary arenavirus platform, today announced that complete HB-200 Phase 1 results (NCT04180215) for single-vector HB-201 and alternating 2-vector HB-202/HB-201 in patients with advanced Human Papillomavirus 16-positive (HPV16+) cancers, including the recommended Phase 2 dose for HB-202/HB-201, will be shared in a poster presentation at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place June 3-7, 2022. Data as of March 31, 2022 will be presented on 68 patients, 54 of whom had head and neck squamous cell carcinoma (HNSCC).
“We look forward to sharing the full Phase 1 data results on our HB-200 program at ASCO. The final analysis shows that HB-201 and 2-vector HB-202/HB-201 were generally well tolerated and showed anti-tumor activity in these difficult-to-treat patients. We also will share additional translational data that continue to show robust tumor-specific T cell responses from use of our HB-200 therapies,” said Joern Aldag, Chief Executive Officer at HOOKIPA. “We are continuing to advance this truly novel science through the clinic, and the learnings from this phase help deepen our understanding of the potential of our technology. These insights inform our path as we advance the 2-vector HB-202/HB-201 immunotherapy into the ongoing Phase 2 HNSCC portion of the study, as well as our approach to our HB-300 program in prostate cancer.”
The abstract is available on the ASCO website with key details noted below:
About the HB-200 trial (NCT04180215)
The Phase 2 part of the trial is open-label with a primary endpoint of preliminary anti-tumor activity, defined by RECIST 1.1, for objective response rate and disease control rate. Secondary endpoints including safety, overall survival, progression-free survival and duration of response. Phase 2 is ongoing, evaluating HB-201 in combination with pembrolizumab in 1st-- and 2nd-line plus settings, with additional arms planned based on final Phase 1 results.
About Human Papillomavirus-driven Cancers
While there are numerous HPV types associated with cancer, HPV16 is the most common cause of cancer. Most HPV infections are cleared from the body with no lasting consequences. However, in some cases, HPV DNA becomes integrated into chromosomal DNA. When host cells take up this DNA, they express the HPV E6 and E7 proteins. This uptake can potentially lead to cancer since expression of these proteins leads to alterations in cell cycle control, which in turn predisposes these cells to become cancerous.
