UTRECHT, The Netherlands and PHILADELPHIA, Aug. 22, 2023 (GLOBE NEWSWIRE) -- LAVA Therapeutics N.V. (Nasdaq: LVTX), a clinical-stage immuno-oncology company focused on developing its proprietary Gammabody® platform of bispecific gamma-delta T cell engagers, today announced recent corporate highlights and financial results for the quarter ended June 30, 2023.

“We are focused on driving forward our lead program, LAVA-1207 in patients with mCRPC and are pleased our Gammabody® platform continues to receive the support of investigators and patients as enrollment remains on track. In addition, we are pleased with the progress of our partnered programs providing additional validation as well as extending our cash runway,” said Steve Hurly, president and chief executive officer of LAVA. “We remain well-positioned to bring meaningful benefits to patients in areas of high unmet need and deliver shareholder value.”

LAVA-1207

Gammabody® designed to target the prostate-specific membrane antigen (PSMA) to trigger the potent and preferential killing of PSMA-positive tumor cells in patients with metastatic castration-resistant prostate cancer (mCRPC). The safety, tolerability and preliminary efficacy of LAVA-1207 in patients with mCRPC are being evaluated in an ongoing dose escalation phase 1/2a, first-in-human study.

• Recruitment is on track and dose escalation continues across 10 sites in a globalized trial in Europe and the United States.
• Currently recruiting dose level 8 for monotherapy treatment.
• Currently recruiting dose level 7 with low-dose interleukin-2.
• The Company expects to report additional safety and efficacy data for the dose escalation phase of the trial in the next twelve months, which may inform the design of a future pivotal trial.

Partnered Programs

• An investigational new drug application clearance for SGN-EGFRd2 (LAVA-1223) in advanced solid tumors was received from the U.S. Food and Drug Administration. Seagen plans to initiate the Phase 1 trial in 2023 (NCT05983133).
• A milestone payment from Janssen Biotech, Inc. (Janssen) was triggered under the terms of the research collaboration agreement (Janssen Agreement) entered in May 2020 when Janssen selected a lead candidate aimed at an undisclosed tumor-associated antigen for further development towards clinical settings. The milestone payment was received in July 2023.

Portfolio Reprioritization and Cash Runway

• In June 2023, LAVA announced the discontinuation of the Phase 1/2a clinical trial of LAVA-051 in patients with relapsed/refractory (R/R) CLL and MM based upon a review of the competitive landscape. The discontinuation was not due to safety concerns.
• Existing patients being evaluated in the Phase 1/2a clinical trial will complete the course of their treatment.
• Portfolio reprioritization resulted in a 36% staff reduction and significant cost savings associated with the discontinuation of LAVA-051. The reduced operating costs align with the Company’s goal of increasing investment in the LAVA-1207 program and extending LAVA’s cash runway into 2026.
  

Second Quarter 2023 Financial Results

The financial information provided below reflects changes made to previously issued consolidated financial statements to revise immaterial prior-period misstatements. Further information regarding the revision is included in LAVA’s consolidated financial statements, "Note 12 — Revision of Immaterial Misstatements," included in Exhibit 99.1 to the report on Form 6-K to be filed with the SEC on the date hereof.

• As of June 30, 2023, LAVA had cash, cash equivalents and investments totaling $112.4 million compared to cash, cash equivalents and investments of $132.9 million as of December 31, 2022. The Company believes its current cash, cash equivalents and investments will be sufficient to fund operations into 2026.
• Revenue from contracts with customers was $5.1 million and $0.5 million for the quarters ended June 30, 2023 and 2022, respectively, and $6.4 million and $1.5 million for the six months ended June 30, 2023 and 2022, respectively. In connection with the license agreement with Seagen, we recognized $2.6 million in revenue for the three months ended June 30, 2023, related to reimbursement for research activities and delivery of initial supply. In connection with the Janssen Agreement, we recognized $2.5 million in revenue for the three months ended June 30, 2023, related to a triggered milestone payment. Revenue from contracts with customers was $0.5 million for the three months ended June 30, 2022, related to the Janssen Agreement.
• Cost of providing services and sales of goods was $2.4 million and $0 for the quarters ended June 30, 2023 and 2022, respectively, and $3.3 million and $0 for the six months ended June 30, 2023 and 2022, respectively. The increase in cost was due to the cost of the initial supply delivery to Seagen and related stability studies.
• Research and development expenses were $12.6 million and $8.4 million for the quarters ended June 30, 2023 and 2022, respectively, and $22.5 million and $15.9 million for the six months ended June 30, 2023 and 2022, respectively. The increase for both periods was primarily due to increased manufacturing scale-up costs and ongoing activities of the clinical trials. In the three months ended June 30, 2023, we have also included $1.4 million in expenses for discontinuance of the activities for LAVA-051.
• General and administrative expenses were $3.7 million and $3.2 million for the quarters ended June 30, 2023 and 2022, respectively, and $7.6 million and $7.4 million for the six months ended June 30, 2023 and 2022, respectively. The increase for both periods was primarily due to the reversal in 2022 of share-based compensation expenses for unvested forfeited options partially offset by lower personnel-related expenses in 2023 due to a reduction in general and administrative headcount.
• Net losses were $12.7 million and $26.6 million for the quarters ended June 30, 2023 and 2022, respectively, or $0.48 and $0.31 net loss per share for the quarters ended June 30, 2023 and 2022, respectively, and $25.3 million and $26.8 million for the six months ended June 30, 2023 and 2022, respectively, or $1.01 and $0.70 net loss per share for the six months ended June 30, 2023 and 2022, respectively.
