"I am very proud of our exceptional research team, whose work has contributed greatly to the scientific discourse and understanding of advanced cancers," said Paul Lévesque, President and CEO at Theratechnologies. "Our investment in the SORT1+ Technology platform over the past five years has generated important evidence on multiple peptide-drug conjugates with different payloads. Now that we have significantly advanced our preclinical program, we are well-positioned to leverage this wealth of data and insights to attract an oncology R&D partner."

The Company will continue to share accumulated preclinical data, including the presentation of two separate posters at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) annual meeting, to be held April 5-9 in San Diego, Calif., one of which features data from new PDCs.

Theratechnologies recently announced the initiation of the next cohort of patients in Part 3 of its Phase 1 trial of sudocetaxel zendusortide, in which the first patient has already received treatment at a higher dose. Recruitment has been ramped up at the six trial sites across North America. To date, more than 40 individuals with various types of cancer have been treated with sudocetaxel zendusortide.

The phasing down of research activities is aligned with the Company’s focus on its commercial business and will further optimize its organizational cost structure, pursuant to the goal of generating positive Adjusted EBITDAi. These changes are expected to result in a restructuring charge of approximately $625,000 in cash charges related to severance and other expenses and approximately $770,000 in non-cash charges. The company anticipates all charges to be fully taken during 2024.

About Sudocetaxel Zendusortide (TH1902) and SORT1+ Technology

Sudocetaxel zendusortide is a first-of-its-kind sortilin receptor (SORT1)-targeting PDC, and the first compound to emerge from the Company’s broader licensed oncology platform. A new chemical entity, sudocetaxel zendusortide employs a cleavable linker to conjugate (attach) a proprietary peptide to docetaxel, a well-established cytotoxic chemotherapeutic agent used to treat many cancers. The FDA granted Fast Track designation to sudocetaxel zendusortide as a single agent for the treatment of all sortilin-positive recurrent advanced solid tumors that are refractory to standard therapy. Sudocetaxel zendusortide is currently being evaluated in a Phase 1 clinical trial.

Theratechnologies has established the SORT1+ TechnologyTM platform as an engine for the development of PDCs that target SORT1, which is expressed in multiple tumor types. SORT1 is a "scavenger" receptor that plays a significant role in protein internalization, sorting, and trafficking. Expression of SORT1 is associated with aggressive disease, poor prognosis, and decreased survival. It is estimated that SORT1 is expressed in 40% to 90% of endometrial, ovarian, colorectal, triple-negative breast (TNBC), and pancreatic cancers, making this receptor an attractive target for anticancer drug development.

Summary of Financial Results for the Full Year 2023

Research and development (R&D) expenses were $19.5 million and $19.0 million for the years ended December 31, 2023 and 2022, respectively. The increase in R&D of $0.5 million is mainly related to the $1.5 million WPD sublicense termination, which enabled the reacquisition of the Company’s intellectual property rights in certain territories, including parts of the European Union. This was offset by $1.0 million in costs related to the timing of costs incurred for clinical trials and sponsored research.

General and administrative (G&A) expenses were $10.0 million and $11.5 million for the years ended December 31, 2023 and 2022, respectively. The decrease in G&A of $1.5 million was mainly attributable to a decrease in regulatory and legal services, and consulting & advisory fees.

The net loss for the year ended December 31, 2023 was $29.8 million, which included a non-cash loss of $1.0 million on warrants in 2023 as compared to a gain of $1.3 million in the prior year and approximately $2.0 million of stock-based compensation expense in 2023 as compared to $2.3 million in 2022.

As of December 31, 2023, the Company had cash and cash equivalents of $23.6 million. The Company believes that this cash is sufficient to meet its projected operating requirements into the fourth quarter of 2024.

"It was a defining year for HOOKIPA as we witnessed the powerful potential of our novel arenaviral immunotherapies in action. Our HB-200 program delivered potentially best-in-class T cell activation and clinical activity, as this program, in combination with pembrolizumab, showed doubled objective response rate compared to historical standard of care treatment alone," said Joern Aldag, Chief Executive Officer of HOOKIPA. "Our progress last year has positioned us to execute in a meaningful way in 2024. Our data enable us to potentially bring a drug to patients who need new treatment options. We are excited for what is ahead for HOOKIPA, and we look forward to sharing more very soon."

Business Highlights and Recent Developments

Oncology

HB-200 in combination with pembrolizumab: positive preliminary Phase 2 data in patients with recurrent/metastatic HPV16+ head and neck cancers in the first line setting. Data was initially presented in May 2023 and additional patient data was provided in October at the European Society for Medical Oncology Congress 2023.
Data from the ongoing study (NCT04180215), showed a 42 percent objective response rate for 19 evaluable checkpoint inhibitor (CPI)-naïve patients treated with HB-200 in combination with pembrolizumab. These data represent a doubling of the historical response rate (19 percent) reported for pembrolizumab alone.
HOOKIPA is preparing to start a randomized Phase 2/3 trial of HB-200 in combination with pembrolizumab in the 1st-line setting for patients with recurrent/metastatic HPV16+ head and neck cancers.

HOOKIPA’s HB-700 program is a novel arenaviral immunotherapy for KRAS-mutated cancers, including the five mutations that are the primary causes of lung, pancreatic and colon cancers.
On January 25, 2024, the Company received notification from Roche of their decision to terminate the collaboration and licensing agreement for HOOKIPA’s HB-700 program. To date, HOOKIPA has met all go-forward criteria under the agreement and remains eligible for a final milestone payment associated with IND submission. HB-700 is on-track to an expected IND application filing by April 2024.
Effective April 25, 2024, HOOKIPA will regain full control of the associated intellectual property portfolio and have full collaboration and licensing rights for this program.

HOOKIPA enrolled the dose escalation cohorts in the Phase 1/2 study of HB-300 (NCT05553639) for the treatment of advanced prostate cancer.
The Study Safety Committee deemed that HB-300 was generally safe and well-tolerated in both dose escalation cohorts.
Initial analysis of target antigen-specific T cell responses—using direct ELISPOT without pre-expansion of T cells—in ten patients between dose level 1 (N=5) and dose level 2 (N=5) indicated a 15- to 26-fold increase of target antigen specific T cells in 30 percent of patients (3/10).
In line with its previously announced strategy to prioritize the development of HB-200, the Company has terminated the Phase 1/2 study of HB-300 and will utilize the associated capital and resources for the advancement of its HB-200 program. HOOKIPA will keep the IND open to allow the potential for further development of this program in the future.
HOOKIPA will publish the final data at a scientific conference, once complete.
Infectious Disease

In August, The Journal of Infectious Disease, published peer-reviewed preclinical data on HB-400, an investigational therapeutic vaccine for chronic hepatitis B (HBV). The data show that HB-400 induced robust, HBV-specific T cell and antibody responses in non-human primates and cleared detectable serum HBV antigens in a mouse model for chronic HBV infection, with near elimination of detectable HBV antigen positive hepatocytes in the liver.
HB-400 (NCT05770895) is currently being evaluated in a Phase 1 trial and is one of two independent development programs in HOOKIPA’s collaboration and license agreement with Gilead Sciences, Inc. Gilead is solely responsible for further development and commercialization of the HBV product candidate.
In November, HOOKIPA’s HB-500 program, an investigational therapeutic vaccine for the treatment of human immunodeficiency virus (HIV), also partnered with Gilead, received FDA clearance of its IND application.
Also in November, Nature Partner Journals Vaccines, published peer-reviewed preclinical data for the program. Data show that HB-500 was well tolerated and generated robust, high-quality and durable immune responses (antigen-specific T cells and antibodies) in non-human primates; and the arenaviral therapeutic vaccination significantly reduced SIV viral load and clinical illness in those animals compared to placebo.
HOOKIPA expects to initiate a Phase 1 clinical study of HB-500 in people with HIV in the second quarter of 2024. Under the collaboration agreement with Gilead, HOOKIPA is eligible for a milestone payment upon dosing the first patient in this study.
Corporate and Financial Updates

Corporate Highlights

The Company added two new Board Members in 2023: Malte Peters, M.D., in January and Terry Coelho in April.
Mark Winderlich, Ph.D., will join the Company on April 1, 2024, as Chief Development Officer to lead HOOKIPA’s clinical research and development organization.
On January 29, 2024, HOOKIPA provided an update on its business priorities and oncology partnership programs. The Company announced that it will focus its resources in two strategic areas: (1) prioritize the clinical development of a randomized trial for its HB-200 program and (2) its two Gilead-partnered infectious disease cure programs for hepatitis B and human immunodeficiency virus. As part of its strategic refocus, HOOKIPA will pause development activities related to HB-300 and most of its preclinical research activities. The Company also announced that it will regain full control of the intellectual property portfolio and will have full collaboration and licensing rights to the HB-700 program for KRAS-mutated cancers from Roche effective April 25, 2024.
Financial Highlights

In January 2023, HOOKIPA achieved a $5.0 million milestone payment under its HB-400 collaboration agreement with Gilead. The success-based milestone payment reflected the Company’s completion and delivery of a regulatory support package for Gilead’s Phase 1 clinical trial.
In February 2023, HOOKIPA achieved a $10.0 million milestone payment under its HB-700 collaboration agreement with Roche. The success-based milestone payment reflected the start of the HB-700 manufacturing process to support a Phase 1 clinical trial.
In June 2023, the Company completed a $50.0 million public offering of common stock and non-voting convertible preferred stock. The financing was completed in parallel with the initial Phase 2 data release for HB-200.
In December 2023, the Company issued 15 million shares of common stock for approximately $21.25 million, at a price of $1.4167 per share, to Gilead under an amended stock purchase agreement between the companies. HOOKIPA has the right, subject to certain terms and conditions, to sell an additional approximately $8.75 million of common stock to Gilead as pro-rata participation in potential future equity raises.

Fourth Quarter and Full Year 2023 Financial Results

Cash Position: HOOKIPA’s cash, cash equivalents and restricted cash as of December 31, 2023 was $117.5 million compared to $113.4 million as of December 31, 2022. The increase was primarily attributable to funds resulting from the follow-on financing in June 2023 and the Gilead stock purchase in December 2023, partly offset by cash used in operating activities.

Revenue: Revenue was $7.4 million and $20.1 million for the three and twelve months ended December 31, 2023, respectively, compared to $7.8 million and $14.2 million for the same periods in 2022. The increase for the twelve months ended December 31, 2023 was primarily due to higher partial recognition of the upfront and milestone payments under the Gilead and Roche collaborations and cost reimbursements for activities related to the preparation of a first human trial under the Roche collaboration, partially offset by lower cost reimbursements received under the Restated Gilead collaboration agreement. The decrease for the three months ended December 31, 2023 was primarily due to a $5.0 million research milestone that was recognized upon achievement related to the Gilead collaboration agreement, partially offset by higher partial recognition of the upfront and milestone payments under the Gilead and Roche collaborations.

Research and Development Expenses: HOOKIPA’s research and development expenses were $21.2 million and $86.4 million for the three and twelve months ended December 31, 2023, respectively, compared to $17.6 million and $68.6 million for the same periods in 2022. The primary drivers of the increase in research and development expenses were higher clinical study expenses for the HB-200 program and increased spending for the HB-700 program.

General and Administrative Expenses: General and administrative expenses amounted to $4.4 million and $18.6 million for the three and twelve months ended December 31, 2023, respectively, compared to $3.8 million and $18.8 million for the same periods in 2022.

Impairment Expenses: Impairment expenses amounted to $12.8 million for the three and twelve months ended December 31, 2023, respectively, and resulted from asset write-offs related to the Company’s GMP manufacturing facility project, that was discontinued as part of the Company’s strategic refocus and rebalance of its cost structure.

Net Loss: HOOKIPA’s net loss was $24.8 million and $81.6 million for the three and twelve months ended December 31, 2023, respectively, compared to $12.3 million and $64.9 million for the same periods in 2022. This increase was primarily due to an increase in research and development expenses and the impairment of the GMP manufacturing facility project.
