●

Enrollment continuing in LAVA-1207 Phase 1/2a trial in metastatic castration-resistant prostate cancer

●

Cash and investments of $110.7 million as of June 30, 2022, providing approximately 2 years of cash runway

●

Appointed James Noble and Jay Backstrom, M.D., M.P.H., as non-executive directors to the Company’s board of directors

Utrecht, The Netherlands, and Philadelphia, USA – September 13, 2022 – 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 to transform the treatment of cancer, today announced recent corporate highlights and financial results for the second quarter ended June 30, 2022.

“In the second quarter, we continued to enroll patients in our two clinical programs, LAVA-051 and LAVA-1207,” said Stephen Hurly, president and chief executive officer of LAVA Therapeutics. “Notably, at ASCO and EHA, we presented encouraging initial dose escalation data from the Phase 1/2a clinical trial of LAVA-051. While still early, we are pleased with LAVA-051’s attractive safety profile and signs of potential anti-tumor activity and are excited about its potential as a therapy that can overcome challenges with current T-cell approaches.”

Recent Pipeline and Business Highlights

LAVA-051

Gammabody targeting CD1d-expressing tumors, including multiple myeloma (MM), chronic lymphocytic leukemia (CLL), and acute myeloid leukemia (AML)

●

Presented initial dose escalation data from the Phase 1/2a clinical trial of LAVA-051 in patients with CLL and MM at the 2022 ASCO Annual Meeting, held June 3-7, 2022, and at the EHA 2022 Congress, held June 9-12, 2022. In addition to demonstrating a favorable safety profile and signs of potential clinical anti-tumor activity, LAVA-051 showed predictable and linear pharmacokinetics and on-mechanism pharmacodynamic parameters consistent with Vγ9Vδ2-T cell engagement, including increasing occupancy of LAVA-051 on patient Vγ9Vδ2-T cells and consistent increases in the expression of T-cell activation markers.

●

Received clearance from the U.S. Food and Drug Administration to enroll patients in the U.S. in the Phase 1/2a clinical trial for the treatment of relapsed or refractory CLL, MM and AML.

●

Hosted a clinical update call featuring Arnon Kater, M.D., Ph.D., chairman of the Dutch/Belgium HOVON CLL working group and professor of translational hematology at the Amsterdam University

Medical Center, and LAVA-051 clinical trial investigator. The call summarized initial Phase 1/2a clinical trial data presented at the 2022 ASCO and EHA meetings and can be accessed on demand at this link.

●

Additional clinical data are expected in the fourth quarter of 2022.

LAVA-1207

Gammabody that targets the prostate-specific membrane antigen (PSMA) to trigger the potent and preferential killing of PSMA-positive tumor cells, including metastatic castration-resistant prostate cancer (mCRPC)

●

Enrollment continues in Europe and the U.S. in the open-label, multi-center Phase 1/2a clinical trial evaluating the tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary antitumor activity of LAVA-1207 in patients with mCRPC. The Phase 1 dose escalation portion will determine the optimal Phase 2 dose to be used in the subsequent Phase 2a expansion cohort.

●

Initial Phase 1 data readout is expected in the fourth quarter of 2022 .

Early-Stage Gammabody Pipeline Development

LAVA-1223, a Gammabody directed at the epidermal growth factor receptor (EGFR) for the treatment of solid tumors which induces tumor cell lysis independent of EGFR downstream signaling mutations (e.g. KRAS/BRAF)

●

A clinical trial application (CTA) and/or IND is planned for late 2022.

Remarked Benjamin Winograd, M.D., Ph.D., chief medical officer, “We are optimistic about LAVA-1223, a Gammabody directed at the epidermal growth factor receptor (EGFR), our second program in solid tumors. EGFR is a well-validated target in a broad range of malignancies. LAVA-1223 has demonstrated the potential to overcome certain limitations of other anti-EGFR drugs, specifically, our LAVA-1223 Gammabody ‘uses’ the EGFR receptor predominantly for homing purposes. As with other Gammabodies, we have observed a tumor preferential effect which may avoid some of the on-target, off tumor adverse effects observed with other anti-EGFR drugs.

LAVA-1266, a CD123 Gammabody for the treatment of hematologic malignancies

●

A CTA and/or IND is planned for late 2023.

Second Quarter Financial Results

The financial information provided below reflects changes made to previously issued condensed consolidated interim financial statements to revise immaterial prior period misstatements. Further information regarding the revision is included in our condensed consolidated interim financial statements, "Note 11 — Revision of Immaterial Misstatements," included as Exhibit 99.1 to this current report on Form 6-K.

●

As of June 30, 2022, LAVA had cash, cash equivalents, and investments totaling $110.7 million compared to cash and cash equivalents of $133.2 million as of December 31, 2021, sufficient to fund the Company into the second half of 2024.

●

Research and license revenue was solely attributable to the company’s collaboration with Janssen Biotech, Inc., which was entered into in May 2020.

●

Research and development expenses were $8.3 million and $15.9 million for the three and six months ended June 30, 2022, respectively, compared to $4.9 million and $23.6 million for the three and six months ended June 30, 2021. The increase for the three months ended June 30, 2022 was primarily driven by increases in clinical trial costs, headcount and other costs incurred in connection with advancing our lead Gammabody^TM clinical candidates, LAVA-051 and LAVA-1207, into human clinical trials. For the six months ended June 30, 2022, the decrease was driven by the $14.3 million VUmc license fees incurred in the first quarter of 2021, partially offset by increases in clinical trial costs, headcount and other costs incurred in connection with advancing our lead Gammabody^TM clinical candidates, LAVA-051 and LAVA-1207, into human clinical trials.

●

General and administrative were $3.0 million and $7.3 million for the three and six months ended June 30, 2022, respectively, compared to $2.8 million and $4.5 million for the three and six months ended June 30, 2021. The increase for both periods was primarily due to costs associated with being a publicly-traded company in the United States, including increases in personnel-related costs and additional insurance, severance, and professional and consultant fees. For the three months that ended June 30, 2022, the increases were partially offset by the reversal of stock-based compensation expense for unvested forfeited stock options.

●

Net losses were $7.9 million and $17.8 million, or $0.31 and $0.69 loss per share, for the three and six months ended June 30, 2022, respectively.
