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)

• Announced the presentation of updated interim data from the ongoing Phase 1/2a clinical trial of LAVA-051 at the ASH 64^th Annual Meeting, being held December 10-13 in New Orleans, LA and virtually. 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, will present abstract #2014, “LAVA-051, a Novel Bispecific Gamma-Delta T-Cell Engager (Gammabody), in Relapsed/Refractory MM and CLL: Pharmacodynamic and Early Clinical Data,” in the session, “Cellular Immunotherapies: Early Phase and Investigational Therapies: Poster I,” on Saturday, December 10, 2022, at 5:30–7:30 p.m. CST.
• Presented clinical pharmacodynamic data from the ongoing Phase 1/2a study that demonstrates consistency with preclinical mechanism of action data for LAVA-051 during the SITC 37^th Annual Meeting.

LAVA-1207
Gammabody targeting 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. Additional clinical data from the Phase 1 dose escalation portion of the trial, which will determine the optimal Phase 2 dose to be used in the subsequent Phase 2a expansion cohort, are expected around year-end 2022. The Company is planning to present these data at an upcoming medical meeting in the first quarter of 2023.
  

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)

• Announced an exclusive global license agreement with Seagen to develop, manufacture and commercialize 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 single digits to the mid-teens on future sales. The agreement also provides Seagen with the opportunity to exclusively negotiate rights to apply LAVA's proprietary Gammabody platform on up to two additional tumor targets.
  

Business Update

• Effective November 1, 2022, LAVA’s Board of Directors appointed Fred Powell as chief financial officer.
  

Third Quarter Financial Results

• As of September 30, 2022, LAVA had cash, cash equivalents and investments totaling $92.7 million compared to cash and cash equivalents of $133.2 million as of December 31, 2021. The cash balance at the end of the third quarter does not reflect the $50 million upfront payment that was received from Seagen in October. Including the payment, the Company’s cash balance is expected to be sufficient to fund the Company beyond 2024.
• Research and license revenue of $15.3 million for the three months ended September 30, 2022 was solely attributable to LAVA’s exclusive global license agreement with Seagen to develop, manufacture and commercialize LAVA-1223. Research and license revenue of $16.8 million for the nine months ended September 30, 2022 included revenue from the Company’s collaboration with Janssen Biotech, Inc., which was entered into in May 2020.
• Research and development expenses were $13.7 million and $29.6 million for the three and nine months ended September 30, 2022, respectively, compared to $6.7 million and $30.3 million for the three and nine months ended September 30, 2021. The increase for the three months ended September 30, 2022 was primarily driven by the initiation and ongoing activities of the clinical trials for LAVA-051 and LAVA-1207 and partner project expenses as well as manufacturing scale-up costs and increased headcount. For the nine months ended September 30, 2022, the decrease was primarily driven by the $14.3 million VUmc license fees incurred in the first quarter of 2021, partially offset by the initiation and ongoing activities of the clinical trials for LAVA-051 and LAVA-1207 and partner project expenses as well as manufacturing scale-up costs and increased headcount.
• General and administrative expenses were $3.1 million and $10.4 million for the three and nine months ended September 30, 2022, respectively, compared to $3.8 million and $8.3 million for the three and nine months ended September 30, 2021. The decrease for the three months ended September 30, 2022 was primarily due to reductions in general and administrative headcount and the reversal of expenses associated with stock option forfeitures, partially offset by additional costs associated with being a public company and temporary staff. The increase for the nine months ended September 30, 2022 was primarily due to additional costs associated with being a public company, insurances established as part of being a public company, severance expenses and temporary staff.
• For the three months ended September 30, 2022, net profit was $0.1 million, or $0.04 per share as compared to $6.9 million net loss, or $0.27 per share for the prior year period. For the nine months ended September 30, 2022, net loss was $16.9 million, or $0.66 per share, as compared to $34.1 net loss, or $1.93 per share for the prior year period. The change from the prior year periods was due primarily to the effects of revenue from the Seagen Agreement.
