• Partial response and stable disease reported in combination cohort, and durable stable disease observed in monotherapy cohorts in the VISTA-101 trial
  
• No dose limiting toxicities observed at any dose level in the VISTA-101 trial
• Cleared fifth of six monotherapy cohorts and second of four combination cohorts in the VISTA-101 trial
• Kineta is actively exploring strategic alternatives to maximize value for all stakeholders

SEATTLE, March 21, 2024 (GLOBE NEWSWIRE) -- Kineta, Inc. (Nasdaq: KA), a clinical-stage biotechnology company with a mission to develop next-generation immunotherapies that transform patients’ lives, announced today financial results for the full year ended December 31, 2023 and provided a corporate update.

In February 2024, the Company announced a significant corporate restructuring to substantially reduce expenses and preserve cash. The restructuring included a significant workforce reduction and the suspension of enrollment of new patients in its ongoing VISTA-101 Phase 1/2 clinical trial evaluating KVA12123 in patients with advanced solid tumors. Patients currently enrolled in the trial will be permitted to continue to participate. The Company announced the restructuring as a result of certain investors indicating that they will not fulfill their April 2024 funding obligation in the previously disclosed private placement financing. In connection with the restructuring, the Company announced that it is exploring strategic alternatives to maximize stockholder value.

“2023 was a productive year for Kineta where we initiated the Phase 1/2 VISTA-101 trial of KVA12123 as monotherapy and in combination with pembrolizumab in cancer patients, and saw promising results, underscoring the potential of KVA12123 as a next-generation immunotherapy. We truly appreciate the efforts of the healthcare professionals, the patients and their caregivers, and the Kineta employees involved in this trial. We look forward to sharing the clinical update in the second quarter and we will continue to explore strategic alternatives that will allow us to continue to pursue our mission of developing transformative immunotherapies for patients with cancer,” said Craig Philips, President of Kineta.

RECENT CORPORATE HIGHLIGHTS

Phase 1/2 VISTA-101 Trial of KVA12123 in Patients with Solid Cancer Tumors

Efficacy

• Announced positive KVA12123 monotherapy safety data from its ongoing Phase 1/2 VISTA-101 clinical trial in patients with advanced solid tumors.
  • Monotherapy Dose Escalation (3–300 mg KVA12123 Q2W)
    • Of 21 patients enrolled, 12 received at least one baseline and one follow up scan.
    • Best overall response (BOR) in nine of 12 patients is currently stable disease among patients with at least one follow-up scan with a mean duration of 15 weeks.
    • One patient with non-small cell lung cancer that failed six prior lines of therapy, including checkpoint inhibitor (CPI) therapy, has experienced a stable disease lasting 28 weeks.
    • Nine participants remain on-treatment. 
  • Combination Therapy Dose Escalation (30-100 mg KVA12123 Q2W, 400 mg pembrolizumab Q6W).
    • Of nine patients enrolled, three received at least one baseline and one follow-up scan.
    • BOR in 2 of 3 patients with at least one follow up scan is:
      • Stable disease in one CPI-failure renal cell carcinoma patient with a 24% reduction in target lesions.
      • Partial response in one patient with a PD-L1 negative mucoepidermoid carcinoma and a 54% reduction in target lesions and a complete response in non-target lesions.
      • Eight patients remain on treatment.

Biomarkers

• Dose-dependent induction of on-target pro-inflammatory cytokines and chemokines.
• Dose-dependent increases in non-classical monocytes, CD4+ and CD8+ T cells, and NK cells.

Safety

• No dose limiting toxicities (DLTs) observed in any patient at any dose level.
• No evidence of cytokine release syndrome in any patient at any dose level.

Conference Presentations

• Co-organized the 3rd Annual VISTA Symposium, with Hummingbird Bioscience and Dartmouth Giesel School of Medicine, to be held virtually on March 27, 2024.
• Presented clinical and preclinical data on VISTA blocking KVA12123 at the Keystone Symposia of Cancer Immunotherapy: Beyond Immune Checkpoint Blockade and Overcoming Resistance.
• Presented new preclinical data on KVA12123 in acute myeloid leukemia (AML) at the American Association for Cancer Research (AACR) Blood Cancer Discovery Symposium.

ANTICIPATED FUTURE MILESTONES

• Additional KVA12123 monotherapy safety and efficacy data in Q2 2024.
• Initial KVA12123 and pembrolizumab combination therapy data in Q2 2024.

EXPLORATION OF STRATEGIC ALTERNATIVES

• In February 2024, the Company announced that it is pursuing strategic alternatives to maximize shareholder value due to certain investors indicating they will not fulfill their April 2024 funding obligation in the previously disclosed private placement financing. As a result, the Company has suspended new patient enrollment into the Phase 1/2 VISTA-101 trial and will not be recruiting patients into either the sixth cohort in the monotherapy arm or the third cohort in the combination therapy arm. Patients currently enrolled in the trial will be permitted to continue to participate. In connection with the restructuring, the Company implemented a workforce reduction of the Company’s workforce of approximately 64% of the Company’s then-current employee base.

2023 FINANCIAL HIGHLIGHTS

• Cash position: As of December 31, 2023, cash was $5.8 million, compared to $13.1 million as of December 31, 2022. The decrease was primarily due to cash used for clinical trial development of KVA12123 as well as general corporate purposes, partially offset by $8.6 million net proceeds received from institutional and individual investors and $5.0 million in cash received from the Merck milestone payment in July 2023. As of December 31, 2023, we had $5.8 million in cash, and there is substantial doubt about our ability to continue as a going concern. Based on our current operating plans, we do not have sufficient cash and cash equivalents to fund our operating expenses and capital expenditures for at least the next 12 months from the filing date of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, which we expect to file on March 21, 2024.

• Revenues: Total revenues were $5.4 million for the year ended December 31, 2023 and $2.0 million for the year ended December 31, 2022. Revenues in 2023 were primarily due to our achievement of a development milestone under the Merck Exclusive License and Research Collaboration Agreement, which triggered a $5.0 million milestone payment. Revenues in 2022 were due to research and development services from the Genentech Option and License Agreement, which was terminated in December 2022, and also due to services provided under a grant that was concluded in December 2022.

• Research and development (R&D) expense: R&D expenses were $9.0 million for the year ended December 31, 2023 and $15.9 million for the year ended December 31, 2022. The decreases in R&D expenses were primarily due to lower activities for KVA12123 manufacturing and clinical study start up as the Company began enrolling the first patient in the study, which occurred in April 2023.

• General and administrative expense: General and administrative expenses were $12.1 million for the year ended December 31, 2023 and $8.7 million for the year ended December 31, 2022. The increase was primarily due to increases in personnel costs of $2.3 million and insurance and other company expenses of $1.1 million. Personnel costs increased due to higher salaries and benefits of $1.2 million from increased headcount to support public company responsibilities and higher stock-based compensation of $1.0 million, which increased due to options granted during 2023. Insurance and other company expenses increased primarily due to public company directors and officers insurance premiums of $601,000 and board fees of $270,000.

• Net loss: Net loss was $14.1 million, or $1.28 per basic and diluted share, for the year ended December 31, 2023 compared to a net loss of $63.4 million, or $12.87 per basic and diluted share, for the year ended December 31, 2022.
