UTRECHT, The Netherlands, and PHILADELPHIA, April 11, 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 fourth quarter and year ended December 31, 2022.

“2022 was a very productive year for LAVA, marked by steady progress in the clinical development of our lead programs, LAVA-051 and LAVA-1207,” said Stephen Hurly, president and chief executive officer of LAVA Therapeutics. “We are encouraged by the initial safety and activity signals and will continue dose escalation in these programs as we work toward a recommended Phase 2 dose. We will also continue to advance our pipeline of bispecific gamma-delta T cell engagers for patients with cancer.”

“On the corporate front, we strengthened our management team with the additions of two seasoned executives, Dr. Charles Morris as chief medical officer and Fred Powell as chief financial officer. Both executives joined LAVA following several decades of experience and proven track records of success in their prior roles. The Company also appointed three highly accomplished independent members to the Board of Directors, which reflects an important progression in the Company’s evolution,” continued Hurly.

Recent Pipeline Highlights

LAVA-051
Gammabody designed to target CD1d-expressing tumors, including multiple myeloma (MM), chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML)

• Initial clinical data for LAVA-051 and presented clinical pharmacokinetic and pharmacodynamic data from the first five patient cohorts of the Phase 1 dose-escalation study that suggest a favorable safety profile, which allowed us to expand the enrollment of patients into planned additional cohorts.
• Potential signs of clinical activity were observed as well as linear PK and on-mechanism PD parameters consistent with Vγ9Vδ2-T cell engagement.
• Clinical trial sites are actively enrolling in North America and Europe.
  

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)

• Initial clinical data suggests a favorable safety profile, with no occurrence of high-grade (>2) cytokine release syndrome.
• Initial signs of anti-tumor activity were observed, with iRECIST stable disease (iSD) in 8 out of 14 evaluable patients at week 8 and PSA levels stabilizing or decreasing in heavily pre-treated patients.
• Clinical trial sites are actively enrolling in sites in North America and Europe.
  

Corporate Update

• LAVA strengthened its executive management team with the following appointments:
  • Dr. Charles Morris was appointed as chief medical officer. Dr. Morris is a medical oncologist with over 25 years of oncology drug development experience and has a proven track record of advancing novel oncology product candidates from clinical development through global regulatory approvals.
  • Fred Powell was appointed chief financial officer and brings over 25 years of experience as a global CFO in the biopharmaceutical industry, having served in this capacity for several publicly traded biopharmaceutical companies.
  • Three new independent directors were appointed to the LAVA Board of Directors: Peter A. Kiener, DPhil, Mary Wadlinger and Christy Oliger. Guido Magni, M.D., Ph.D., and Stefan Luzi, Ph.D., stepped down from the Board.

• In September 2022, we announced an exclusive global license agreement with Seagen pursuant to which we granted a worldwide exclusive license to Seagen to develop, manufacture and commercialize SGN-EGFRd2 (LAVA-1223), an advanced preclinical asset that utilizes LAVA’s proprietary Gammabody technology to target EGFR-expressing solid tumors. Under the terms of the agreement, LAVA received a $50 million upfront payment and could receive up to approximately $650 million in potential development, regulatory and commercial milestones, and royalties ranging from the high single digits to the mid-teens on future sales.
  

Fourth Quarter and Year-End 2022 Financial Results

Further information regarding the revision is included in our consolidated financial statements, "Note 23 — Revision of Immaterial Misstatements," included in Item 18 of our annual report on Form 20-F.

• As of December 31, 2022, LAVA had cash, cash equivalents and investments totaling $132.9 million compared to cash and cash equivalents of $133.2 million as of December 31, 2021. The cash balance is expected to be sufficient to fund the Company’s activities into 2026.
• Research and license revenue was $2.6 million and $1.1 million for the quarters ended December 31, 2022 and 2021, respectively, and $19.4 million and $5.4 million for the years ended December 31, 2022 and 2021, respectively. The full-year increase was primarily due to $17.9 million in revenue from the Company’s collaboration with Seagen Inc.
• Research and development expenses were $10.5 million and $6.6 million for the quarters ended December 31, 2022 and 2021, respectively, and $40.1 million and $36.9 million for the years ended December 31, 2022 and 2021, respectively. The higher quarterly and full-year expense was due to ongoing activities of the clinical trials for LAVA-051 and LAVA-1207, which were offset by a one-time license fee of $14.4 million triggered in the first quarter of 2021 by the IPO.
• General and administrative expenses were $3.7 million and $3.8 million for the quarters ended December 31, 2022 and 2021, respectively, and $14.1 million and $12.0 million for the years ended December 31, 2022 and 2021, respectively. The increase for the full year 2022 was due to higher personnel-related expenses and the costs of being a public company for a full year compared to only 9 months in 2021.
• Net losses were $15.0 million and $8.2 million for the quarters ended December 31, 2022 and 2021, respectively, or $0.57 and $0.32 net loss per share for the quarters ended December 31, 2022 and 2021, respectively, and $31.9 million and $42.4 million for the years ended December 31, 2022 and 2021, respectively, or $1.23 and $2.14 net loss per share for the years ended December 31, 2022 and 2021, respectively.
