Item 7.01 Regulation FD Disclosure.
On June 22, 2020, HOOKIPA Pharma Inc. (the “Company”) announced positive Phase 2 interim safety and immunogenicity results for its cytomegalovirus, or CMV, vaccine candidate HB-101. A copy of the press release is attached hereto as Exhibit 99.1.
The information in this Item 7.01 of Form 8-K, including the accompanying Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”), or otherwise subject to the liability of such section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, regardless of the general incorporation language of such filing, except as shall be expressly set forth by specific reference in such filing.
Item 8.01 Other Events.
On June 22, 2020, the Company announced positive interim results on its prophylactic CMV vaccine candidate HB-101. HB-101 is being investigated in a double-blind Phase 2 clinical trial to assess safety, immunogenicity and efficacy in patients receiving a kidney transplant from a live donor. The Company reported that HB-101 was observed to be well tolerated with fewer adverse events in patients with end-stage kidney disease than in the Company's previous Phase 1 clinical trial of HB-101 in healthy volunteers. Patients who received three doses of HB-101 showed comparable immunogenicity to healthy volunteers in the Company's Phase 1 clinical trial of HB-101. In addition, in available samples, patients who received three doses of HB-101 had a CMV-specific cellular immune response.

HOOKIPA Announces Positive Phase 2 Interim Safety and Immunogenicity Results for its CMV Vaccine Candidate HB-101
|·||Interim data demonstrate that HB-101 is well tolerated|
|·||HB-101 elicits T cell and B cell responses in the target population|
New York, US and Vienna, Austria, June 22, 2020 - HOOKIPA Pharma Inc. (NASDAQ: HOOK, ‘HOOKIPA’), a company developing a new class of immunotherapeutics targeting infectious diseases and cancers based on its proprietary arenavirus platform, today announced positive interim results on its prophylactic Cytomegalovirus (CMV) vaccine candidate HB-101. HB-101 is being investigated in a double-blind Phase 2 clinical trial (NCT03629080) to assess safety, immunogenicity and efficacy in patients receiving a kidney transplant from a live donor. HOOKIPA reported interim data on the trial’s primary endpoints, safety and B cell and T cell immunogenicity.
Trial participants were blinded and randomized 2:1 to receive either HB-101 or placebo. Patients received either 2 or 3 doses prior to transplantation, depending on the transplantation time schedule.
Tolerability profile of HB-101
Safety and tolerability were evaluated in 51 CMV-negative patients prior to kidney transplantation. Of the 51 patients, only eight patients (16%) across the combined, blinded HB-101 and placebo groups showed adverse events related to the administration. Most of these adverse events were of mild intensity, indicating that HB-101 is generally well tolerated in this patient population. Of note, this target patient population reported fewer adverse events than the 54 healthy volunteers in HOOKIPA’s recently published Phase 1 trial results1.
CMV-neutralizing antibody response to HB-101
For the interim analysis, CMV-neutralizing antibody titers on the day of transplantation were evaluated in all of the 30 CMV-negative patients who had been transplanted by the cutoff date and had valid results. Nineteen of the 30 patients received HB-101 and eleven received placebo. All five patients (100%) who received three doses of HB-101 mounted CMV-neutralizing antibodies. Three of the fourteen patients (21%) who received only two doses of HB-101 also mounted CMV-neutralizing antibodies. The antibody response of the kidney transplant recipients who completed the three-dose regimen was comparable to the antibody response observed in the Phase 1 trial.
T cell responses to HB-101
Cellular immune responses to CMV on the day of transplantation were evaluated in 25 CMV-negative patients who had been transplanted in time for this interim analysis. Technically valid results from T cell assays on the day of transplantation were available for seven recipients (as a consequence of sample logistics and assay performance). Two of the seven patients received placebo and five received HB-101. All three patients (100%) who received three doses of HB-101 and one of the two patients who received only two doses (50%) mounted a

CMV-specific cellular immune response.
The interim data demonstrate that HB-101 is well tolerated with fewer adverse events in patients with end-stage kidney disease than in the previous healthy volunteer trial. Patients who received three doses of HB-101 show comparable immunogenicity to healthy volunteers in HOOKIPA’s Phase 1 clinical trial of HB-101.
“The interim results demonstrate that the vaccine is well-tolerated and immunogenic in patients with end-stage kidney disease,” said Joern Aldag, CEO. “We are excited that we are seeing strong antibody and T cell responses, in particular in patients who received three administrations. We continue patient accrual and plan to report preliminary efficacy data and updated safety and immunogenicity data by the end of 2020.”

Cytomegalovirus, or CMV, is a virus that is commonly transmitted in childhood and early adulthood. Approximately 60% of the U.S. population has been exposed and is latently infected. Worldwide data indicate that half the people in industrialized countries and up to 99% of people in developing countries, including China and India, have been infected. Infections typically result in lifelong latent persistence of the virus with few symptoms, if any. However, in unborn children, when infected in utero, CMV infection can lead to significant morbidity and mortality. In addition, in immunosuppressed patients, such as transplant recipients, primary CMV infection or reactivation of CMV causes significant morbidity, mortality and graft rejection.
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 technologies are designed to allow for repeat administration to augment and refresh immune responses. TheraT® has the potential to induce CD8+ T cell response levels previously not achieved by other immuno-therapy approaches. HOOKIPA’s “off-the-shelf” viral vectors target dendritic cells in vivo to activate the immune system.
HOOKIPA’s VaxWave®-based prophylactic Cytomegalovirus (CMV) vaccine candidate is currently in a Phase 2 clinical trial in CMV-negative patients awaiting kidney transplantation from living CMV-positive donors as well as CMV-positive patients awaiting kidney transplantation from CMV-positive or -negative 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 chronic Hepatitis B infections.
In addition, HOOKIPA is building a proprietary immuno-oncology pipeline by targeting virally mediated cancer antigens, self-antigens and next-generation antigens. The TheraT® based lead oncology product candidates, HB-201 and HB-202, are in development for the treatment
of Human Papilloma Virus 16-positive cancers. The Phase 1/2 clinical trial for HB-201 was initiated in December 2019. The HB-202 IND application was cleared by the FDA in June 2020.
