  • Alternating, intravenous administration of two replicating arenaviral vectors induce tumor-specific responses exceeding 50% of the circulating CD8 T cells
  • 2-vector method resulted in tumor cures and long-term immunity in opposition to tumor rechallenge
  • Publication underscores the potential of HOOKIPA’s engineered arenavirus platform as a brand new class of most cancers immunotherapeutics, presently being evaluated in a Section 1/2 scientific trial in HPV16+ cancers

NEW YORK and VIENNA, Austria, March 04, 2021 (GLOBE NEWSWIRE) — HOOKIPA Pharma Inc. (NASDAQ: HOOK, ‘HOOKIPA’), an organization creating a brand new class of immunotherapeutics primarily based on its proprietary arenavirus platform, at the moment introduced the publication of pre-clinical information highlighting the potential of its alternating 2-vector, intravenously administered most cancers therapeutics within the peer-reviewed journal, Cell Stories Drugs. The publication, which is obtainable on-line now, will seem within the 16 March print subject.

“The pre-clinical information revealed in Cell Stories Drugs underscore the potential of our engineered arenavirus platform to redefine success in most cancers immunotherapy. Particularly, our alternating 2-vector method delivered a considerable tumor-specific response, leading to tumor cures and long-term anti-tumor immunity in a pre-clinical setting,” stated Joern Aldag, Chief Govt Officer at HOOKIPA. “The information on this peer-reviewed publication present the scientific substantiation for the continued scientific trial of the alternating 2-vector remedy for Human Papillomavirus 16-positive (HPV16+) cancers in addition to for advancing to prostate most cancers.”

Pre-clinical information featured within the article confirmed that intravenous, alternating administration of two totally different replicating arenaviral vectors that specific the identical antigen induces potent T cell response, exceeding 50% of the circulating T cell pool, and strong anti-tumor exercise. The anti-tumor exercise and really excessive T cell technology had been demonstrated each with onco-viral antigens and in addition with a most cancers self-antigen, illustrating the power of the arenaviral platform to interrupt tolerance.

Different key highlights from the paper embrace:

  • Single-vector and alternating 2-vector remedy didn’t induce vector-neutralizing antibodies, supporting repeated intravenous administration
  • Mice that cleared tumors after remedy had been shielded from tumor re-challenge
  • Increasing on the information noticed with single-vector remedy, alternating 2-vector remedy induced a good increased T cell response and extra environment friendly tumor management

The examine on which this publication is predicated, was performed and led by a global group of researchers on the College of Basel.

HB-201 and HB-202 use the LCMV and PICV arenaviral backbones, respectively, whereas expressing the identical antigen, an E7/E6 fusion protein derived from HPV16. Interim Phase 1 monotherapy data on HB-201 for the remedy of superior HPV16+ cancers confirmed promising anti-tumor exercise and favorable tolerability. Information demonstrated responses and secure illness in head and neck most cancers sufferers who failed prior normal of care remedy, platinum remedy, PD(L)1 inhibitor, or each.
