"In the second quarter, we released positive interim safety and immunogenicity results from our Phase 2 trial of HB-101 to prevent Cytomegalovirus (CMV) infections. HB-101 was observed to be well tolerated and immunogenic in patients with end-stage kidney disease. Antibody and T cell immunogenicity data confirm our Phase 1 results," commented Joern Aldag, HOOKIPA’s Chief Executive Officer. "Furthermore, our immuno-oncology trial using HB-201 monotherapy for patients with HPV16+ tumors is progressing well and has recently completed enrollment at the second dose level in the intravenous group. The HB-202 Investigational New Drug (IND) was cleared by the U.S. Food and Drug Administration (FDA), allowing the alternating use of two vectors (HB-202 + HB-201) in this trial. We expect to begin treating HPV16+ patients with this new alternating, two-vector therapy in late 2020. We plan to report further data on the HB-101 program by the end of 2020 and initial data from the HB-201 monotherapy program by late 2020/early 2021."
R&D Pipeline Update and Clinical Progress
HB-101, lead product candidate in infectious diseases
HOOKIPA’s prophylactic Cytomegalovirus (CMV) vaccine candidate, HB‑101, is in a randomized, double‑blinded Phase 2 clinical trial in patients awaiting kidney transplantation who are at risk for CMV-associated complications post-transplant. In June 2020, HOOKIPA announced positive Phase 2 interim data on the trial’s primary endpoints: safety, and B cell and T cell immunogenicity. The interim data demonstrated that HB‑101 was well tolerated, with a lower rate of adverse events in patients with end-stage kidney disease than in the Phase 1 healthy volunteer trial. Patients who received the protocol recommended three doses of HB‑101 showed comparable immunogenicity levels to those measured in the Phase 1 healthy volunteer trial. HOOKIPA continues to accrue patients, and plans to report preliminary efficacy and updated safety and immunogenicity data by the end of 2020.
HB-201 and HB-202, lead programs in immuno-oncology treating Human Papillomavirus-positive cancers
HOOKIPA’s lead oncology product candidates, HB‑201 and HB‑202, are in development for the treatment of Human Papillomavirus 16‑positive (HPV16+) cancers. In December 2019, HOOKIPA initiated the Phase 1/2 clinical trial for HB-201. The open label, dose escalating Phase 1/2 clinical trial is evaluating HB-201 in HPV16+ cancers alone and in combination with an approved checkpoint inhibitor. HOOKIPA plans to enroll 100 patients in total with 20 patients in each dose escalation and expansion group, respectively. Enrollment of patients at the intravenously administered first and second dose levels has been completed. HOOKIPA expects to report preliminary safety and efficacy data in late 2020 or early 2021.
In June 2020, HOOKIPA announced that the FDA cleared its IND Application for HB-202. With the IND clearance, HOOKIPA will be able to examine not only the safety and efficacy of HB‑201 alone but also HB-201 in combination with HB-202 as an alternating, two-vector therapy. The planned clinical trial combining HB-202 with HB-201, also in patients with HPV16+ cancers, is an open label, dose escalation Phase 1/2 trial with the primary endpoint to evaluate safety and tolerability. That trial is expected to commence later in 2020.
In August 2020, the United States Patent and Trademark Office (USPTO) and the European Patent Office issued patents to the University of Geneva, licensed exclusively to HOOKIPA, that cover HOOKIPA´s proprietary replicating arenavirus technology (TheraT), including HB-201 and HB-202. The USPTO also granted a patent specifically related to HB-201 and HB-202 product candidates.
Strategic Collaborations
Gilead Sciences Collaboration for HIV and HBV Therapeutic Vaccines
Since the start of the collaboration in 2018, HOOKIPA received $21.0 million in upfront and milestone payments from Gilead for the delivery of research vectors and for advancing the programs towards clinical trials, including a milestone payment of $4.0 million, which the Company received in early 2020. Based on preclinical data generated to date, Gilead committed to advancing the HBV and HIV vectors toward development. To enable the development activities and expanded research programs, Gilead agreed to reserve manufacturing capacity and increase reimbursement planned for the Company’s expanded resources allocated to the Gilead collaboration. The HOOKIPA team has continued to meet all milestones agreed with Gilead on time despite the pandemic.
COVID-19
HOOKIPA continues to monitor the COVID-19 situation closely and to adapt to the COVID-19 measures and recommendations issued by the US and Austrian governments. For disclosures of risks and uncertainties resulting from the COVID-19 disease outbreak, including the impact on the enrollment of patients and timing of clinical results, see HOOKIPA’s quarterly report on Form 10-Q for the quarter ended June 30, 2020.
Second Quarter 2020 Financial Results
Cash Position:
HOOKIPA’s cash, cash equivalents and restricted cash as of June 30, 2020 was $93.3 million compared to $113.6 million as of December 31, 2019. The decrease was primarily attributable to cash used in operating activities.
Revenue was $6.7 million for the three months ended June 30, 2020 compared to $4.1 million for the three months ended June 30, 2019. The increase was primarily due to higher cost reimbursements received under the collaboration agreement with Gilead and the partial recognition of a milestone payment we received from Gilead in February 2020.
Research and Development Expenses:
HOOKIPA’s research and development expenses were $11.6 million for the three months ended June 30, 2020 compared to $13.9 million for the three months ended June 30, 2019.
The primary drivers of the decrease compared to 2019 were a decrease in manufacturing and quality control expenses of $2.0 million along with a general decrease in other direct R&D expenses of $1.1 million.
General and Administrative Expenses:
General and administrative expenses amounted to $4.3 million for the three months ended June 30, 2020 compared to $3.8 million for the three months ended June 30, 2019. The increase was primarily due to an increase in personnel-related expenses and in costs associated with ongoing business activities and operating as a public company, which was partially offset by a decrease in professional and consulting fees which resulted from the prior-year effect related to the closing of the Company’s initial public offering in April 2019.
Net Loss:
HOOKIPA’s net loss was $7.1 million for the three months ended June 30, 2020 compared to a net loss of $12.1 million for the three months ended June 30, 2019.
