Phase 1/2 trial to be HOOKIPA’s first clinical trial in immuno-oncology


HOOKIPA Pharma Inc. (NASDAQ: HOOK), a company developing a new class of immunotherapeutics targeting infectious diseases and cancers based on its proprietary arenavirus platform, today announced that its Investigational New Drug (IND) Application for a Phase 1/2 clinical trial of HB-201, a TheraT®*-based immunotherapy, for the treatment of Human Papilloma Virus (HPV)-positive cancers is now effective following the clearance by the U.S. Food and Drug Administration (FDA).

HB-201 (LCMV) is a TheraT®-based product candidate expressing a non-oncogenic but highly antigenic E6/E7 fusion protein derived from HPV16. In animal models, HB-201 was observed to induce strong immunogenicity, resulting in a robust E6 and E7 antigen specific CD8+ T cell response. HOOKIPA will now start a clinical trial with the goal to provide therapeutic benefit to patients with HPV16+ cancers. Based on the magnitude of response shown in pre-clinical models, HOOKIPA believes that HB-201 has the potential to induce levels of CD8+ T cells that were previously only attainable with adoptive cell therapies. However, HOOKIPA’s approach is designed to directly reprogram the patient’s immune system with an off the shelf systemic administration. This approach eliminates the need for any ex vivo logistics that burden adoptive cell therapy and any related ex vivo cellular approaches.

HOOKIPA intends to start the Phase 1/2 clinical trial in the second half of 2019 with preliminary safety and efficacy data expected in late 2020 or early 2021. It will be HOOKIPA’s first clinical trial in immuno-oncology. In addition to obtaining both safety and efficacy of the targeted patient population, this program will also have a built-in translational component which will allow HOOKIPA to validate its mechanism of action within patients and further drive clinical development via a rigorous scientific method.

Joern Aldag, HOOKIPA’s Chief Executive Officer, said: “With the FDA’s clearance of our IND application we have achieved an important milestone advancing HB-201 into clinical development. We aim to prove that our technology platform can effectively super-charge the natural defense mechanisms in humans and deliver prevention or cure for the benefit of seriously ill patients.”


About TheraT®

HOOKIPA’s proprietary TheraT® technology is a replication-attenuated arenavirus, designed to allow for repeat administration while maintaining an immune response. TheraT® has the potential to induce CD8+ T cell response levels previously not achieved by other published immuno-therapy approaches. Unlike naturally occurring arenaviruses, which have two genomic segments, our TheraT® constructs were engineered to have three segments in order to allow for the introduction of genomic space in which to insert additional target antigens of choice. As a result of the larger genome, the virus’ ability to replicate is attenuated.


About Human Papilloma Virus (HPV) - associated head and neck cancers

Human papilloma virus (HPV) is estimated to cause about 5% of the worldwide burden of cancer including approximately 99% of cervical cancers, 25% to 60% of head and neck cancers, 70% of vaginal cancers and 88% of anal cancers. The majority of these cancers are caused by the HPV serotype 16. Most infections with HPV 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 can potentially lead to cancer, since expression of these proteins leads to alterations in cell cycle control, which in turn predisposes these cells to becoming cancerous.


About HOOKIPA

HOOKIPA Pharma Inc. (NASDAQ: HOOK) is a clinical stage biopharmaceutical company developing a new class of immunotherapeutics, targeting infectious diseases and cancers based on its proprietary arenavirus platform that is designed to reprogram the body’s immune system.

HOOKIPA’s proprietary arenavirus-based technologies, VaxWave®*, a replication-deficient viral vector, and TheraT®*, a replication-attenuated viral vector, are designed to induce robust antigen specific CD8+ T cells and pathogen-neutralizing antibodies. Both, VaxWave® and TheraT®, are designed to allow for repeat administration while maintaining an immune response. TheraT® has the potential to induce CD8+ T cell response levels previously not achieved by other published immuno-therapy approaches. HOOKIPA’s “off-the-shelf” viral vectors target dendritic cells in vivo to activate the immune system.

HOOKIPA has successfully completed a Phase 1 trial of a VaxWave®-based prophylactic vaccine to protect against cytomegalovirus infection and has started dosing patients in a Phase 2 trial in cytomegalovirus-negative patients awaiting kidney transplantation from cytomegalovirus-positive donors. To expand its infectious disease portfolio, HOOKIPA has entered into a collaboration and licensing agreement with Gilead Sciences, Inc. to jointly research and develop functional cures for HIV and Hepatitis B infections. HOOKIPA is building a proprietary immuno-oncology pipeline by targeting virally mediated cancer antigens, self-antigens and next-generation antigens.

TheraT® and VaxWave® are not approved anywhere globally and their safety and efficacy have not been established.
