“The year began with an exciting start as we opened our first-in-human clinical trial of KVA12123 and dosed our first patient in the Phase 1/2 study in advanced solid tumors.

FIRST QUARTER 2023 FINANCIAL HIGHLIGHTS

• Cash position: As of March 31, 2023, cash was $9.2 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 $0.8 million net proceeds received from the sale of 126,503 shares of our common stock in connection with an at-the-market equity offering program. We believe our cash position as of March 31, 2023, together with the $5.5 million net proceeds received in April 2023 plus the committed proceeds of $22.5 million pursuant to the second closing of the private placement expected in July 2023, will be sufficient to fund operating expenses and capital expenditure requirements into early 2025.
• Research and development (R&D) expense: R&D expenses were $2.8 million for the three months ended March 31, 2023 compared to $4.0 million for the three months ended March 31, 2022. The decrease in R&D expenses was primarily due to lower activities for KVA12123 as we began securing clinical trial sites and enrolling patients in advance of enrolling the first patient, which occurred in April 2023. We expect our R&D expenses to increase over time this year as we enroll and dose additional patients.
• General and administrative expense: General and administrative expenses were $3.9 million for the three months ended March 31, 2023 compared to $1.6 million for the three months ended March 31, 2022. The increase was primarily due to higher personnel-related costs from non-cash stock-based compensation with performance conditions contingent upon the closing of the reverse merger and increased public company expenses such as professional services fees and insurance.
• Net loss: The Company reported a net loss of $6.5 million, or $0.77 per basic and diluted share, compared to a net loss of $5.0 million, or $1.07 per basic and diluted share, for the prior year.

About Kineta
Kineta (Nasdaq: KA) is a clinical-stage biotechnology company with a mission to develop next-generation immunotherapies that transform patients’ lives. Kineta has leveraged its expertise in innate immunity and is focused on discovering and developing potentially differentiated immunotherapies that address the major challenges with current cancer therapy.

KVA12123 (formerly referred to as KVA12.1) is expected to be a differentiated VISTA blocking immunotherapy to address the problem of immunosuppression in the tumor microenvironment. It is a fully human engineered IgG1 monoclonal antibody that was designed to bind to VISTA through a unique epitope. KVA12123 may be an effective immunotherapy for many types of cancer including NSCLC (lung), colorectal, renal cell carcinoma, head and neck, and ovarian. These initial target indications represent a significant unmet medical need with a large worldwide commercial opportunity for KVA12123.
