Item 2.02 Results of Operations and Financial Condition.

On May 11, 2023, HOOKIPA Pharma Inc. (the “Company”) announced Financial Results for the First Quarter 2023. A copy of the press release is being furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information in this Current Report on Form 8-K and Exhibit 99.1 attached hereto is intended to be furnished and 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 liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 8.01 Other Events.

In April, the Company presented preclinical data resulting from an exploratory, non-commercial research effort as an oral presentation at the American Association for Cancer Research Annual Meeting highlighting the potential of its arenaviral immunotherapy in combination with Roche’s targeted PD1-IL2 variant (PD1-IL2v) as a potential promising next-generation immunotherapy. The data show that PD1-IL2v treatment subsequent to arenaviral immunotherapy further strengthens T cell responses, resulting in strong anti-tumor activity and high tumor cure rates. Similar results were seen for both tumor-associated oncoviral antigens and self-antigens, underscoring the potential of the combination for multiple tumor types.

HOOKIPA Pharma Reports First Quarter 2023 Financial Results
and Recent Business Highlights

HOOKIPA on track to report Phase 2 data on HB-200 for head and neck cancer in combination with pembrolizumab in 2Q 2023
Phase 1 clinical trials initiated for two programs (HB-300 for advanced prostate cancer and Gilead-partnered HB-400 for chronic hepatitis B)
HB-700 for KRAS-mutated cancers achieved $10 million milestone payment in Roche collaboration

NEW YORK and VIENNA, May 11, 2023 - HOOKIPA Pharma Inc. (NASDAQ: HOOK, ‘HOOKIPA’), a company developing a new class of immunotherapeutics based on its proprietary arenavirus platform, today reported financial results and business highlights for the first quarter of 2023.

“We are happy to report continued progress across our oncology and infectious disease portfolios, as our HB-300 program for advanced prostate cancer and Gilead-partnered HB-400 program for the treatment of chronic hepatitis B both entered the clinic. Further, our HB-700 program in collaboration with Roche achieved a success-based milestone payment associated with manufacturing for our clinical supplies,” said Joern Aldag, Chief Executive Officer at HOOKIPA. “We are on track to report Phase 2 data from our lead program, HB-200 in combination with pembrolizumab, in the second quarter of 2023, which is an exciting step forward as we expect the results to inform our next, potentially registrational trial."

Quarter highlights


In February, HOOKIPA announced that it had achieved a $10 million milestone payment under its collaboration agreement with Roche to develop HB-700, a novel arenaviral immunotherapy for KRAS-mutated cancers. The success-based milestone payment reflects the start of the HB-700 manufacturing process to support a Phase 1 clinical trial.

In April, HOOKIPA announced the acceptance of a trial-in-progress presentation at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting on its ongoing Phase 1/2 study of HB-300 for the treatment of advanced prostate cancer. Enrollment is ongoing and initial data are expected in the first half of 2024.

Infectious disease

In January, HOOKIPA recieved a $5 million milestone payment under its collaboration agreement with Gilead Sciences for the completion of the regulatory support package for Gilead’s Phase 1 clinical trial of HB-400, an alternating, 2-vector non-replicating arenaviral therapeutic vaccine for the treatment of chronic hepatitis B. The first participant was dosed in April 2023. Gilead is solely responsible for further development and commercialization of the hepatitis B product candidate.


In March, HOOKIPA announced the appointment of Terry Coelho to its Board of Directors, Audit Committee and Compensation Committee. Terry brings more than 35 years of experience in business strategy, broad financial transactions and business development of large pharmaceutical and smaller biotechnology companies.

First Quarter 2023 Financial Results

Cash Position: HOOKIPA’s cash, cash equivalents and restricted cash as of March 31, 2023 was $110.0 million compared to $113.4 million as of December 31, 2022. The decrease was primarily attributable to cash used in operating activities, partly offset by funds resulting from the Gilead and Roche collaborations.

Revenue: Revenue was $3.2 million for the three months ended March 31, 2023 compared to $1.4 million for the three months ended March 31, 2022. The increase was primarily due to higher recognition of upfront and milestone payments under the Gilead and Roche collaborations, partially offset by lower cost reimbursements received under the Gilead collaboration.

Research and Development Expenses: HOOKIPA’s research and development expenses were $20.9 million for the three months ended March 31, 2023, compared to $16.6 million for the three months ended March 31, 2022. The primary drivers of the increase in research and development expenses by $4.3 million compared to the three months ended March 31, 2022 were higher clinical study expenses for our HB-200 program and higher expenses for research and development services for our HB-200 program, as well as increased spending for our Gilead and Roche partnered programs, partially offset by lower manufacturing expenses for our HB-200 and Gilead partnered programs.

General and Administrative Expenses: General and administrative expenses amounted to $4.9 million for the three months ended March 31, 2023, compared to $5.0 million for the three months ended March 31, 2022. The decrease compared to the three months ended March 31, 2022 was primarily due to a decrease in professional and consulting fees and in other expenses, partially offset by an increase in personnel-related expenses.

Net Loss: HOOKIPA’s net loss was $19.7 million for the three months ended March 31, 2023, compared to a net loss of $18.0 million for the three months ended March 31, 2022. This increase was primarily due to an increase in research and development expenses, partially offset by an increase in revenues from collaboration and licensing, and an increase in grant income, and a decrease in general and administrative expenses.
