Conference Call with Slides Begins at 4:30 p.m. Eastern Time Today

OmniAb, Inc. (NASDAQ: OABI) today reported financial results for the three and six months ended June 30, 2023, and provided operating and partner program updates.

“Our business continued to grow and perform well during the second quarter with advancements in business development and progress across partner programs. The addition of four new partners during the quarter, including Merck & Co. and Neurocrine Biosciences, highlights the relevance and robustness of our technology platform. Existing partners made progress with two new programs entering the clinic and the total number of active programs increased to 305,” said Matt Foehr, Chief Executive Officer of OmniAb, Inc.

“Our ion channel business continues to identify and explore high-value targets and one of the GSK programs achieved a key milestone in its discovery process. We look forward to providing updates related to our current partners as well as to securing additional partnerships,” he added.

Second Quarter 2023 Financial Results

Revenue for the second quarter of 2023 was $6.9 million, compared with $7.2 million for the same period in 2022. Milestone revenue was higher due to progress with the batoclimab program. Service revenue was lower primarily related to the completion of work on certain ion channel programs and a one-time adjustment related to the extension of one of our programs with GSK, partially offset by the recognition of a portion of a research progression milestone achieved in the quarter.

Research and development expense was $14.1 million for the second quarter of 2023, compared with $11.5 million for the same period in 2022, with the increase primarily due to higher personnel and facility costs. General and administrative expense was $8.7 million for the second quarter of 2023, compared with $5.0 million for the same period in 2022, with the increase primarily due to higher personnel costs and expenses related to being an independent publicly traded company.

Net loss for the second quarter of 2023 was $14.7 million, or $0.15 per share, compared with a net loss of $10.3 million, or $0.12 per share, for the same period in 2022.

Year-to-Date Financial Results

Revenue for the six months ended June 30, 2023 was $23.9 million, compared with $16.8 million for the same period in 2022. Milestone revenue was higher, primarily due to the recognition of a $10.0 million milestone payment related to the first commercial sale of TECVAYLI^® (teclistamab) in the European Union and progress with the batoclimab program. Service revenue was lower primarily related to the completion of work on certain ion channel programs and a one-time adjustment related to the extension of one of our programs with GSK, partially offset by the recognition of a portion of a research progression milestone achieved in the quarter.

Research and development expense was $27.9 million for the six months ended June 30, 2023, compared with $22.3 million for the same period in 2022, with the increase primarily due to higher personnel and facility costs. General and administrative expense was $16.9 million for the six months ended June 30, 2023, compared with $9.1 million for the same period in 2022, with the increase primarily due to higher personnel costs and expenses related to being an independent publicly traded company.

Net loss for the six months ended June 30, 2023 was $20.8 million, or $0.21 per share, compared with a net loss of $16.6 million, or $0.20 per share, for the same period in 2022.

As of June 30, 2023, OmniAb had cash, cash equivalents and short-term investments of $103.1 million. The Company continues to expect its cash, cash equivalents and short-term investments balance at year-end 2023 to be slightly higher than year-end 2022. Current cash, cash equivalents and short-term investments, along with the cash OmniAb generates from operations, are expected to be sufficient to fund operations for the foreseeable future.

On November 1, 2022, OmniAb completed a spin-off from Ligand Pharmaceuticals Incorporated (NASDAQ: LGND), resulting in OmniAb becoming an independent publicly traded company. Financial results prior to November 1, 2022, are presented on a carve-out basis derived from Ligand’s historical accounting records, as if OmniAb were an independent company.

Second Quarter 2023 and Recent Business Highlights

During the second quarter of 2023, OmniAb entered into four new license agreements including with Merck & Co., Inc., Neurocrine Biosciences Inc., Stanford University and Seattle Children’s Hospital. These additions bring the total active partner count to 74.

Programs by OmniAb’s partners continued to progress during the quarter, including two entering the clinic. Immunovant’s IMVT-1402, a next-generation FcRn antagonist, and Gloria’s GLS-012 (anti-LAG-3), initiated Phase 1 clinical trials in China. In addition, the Biologics License Application for batoclimab was accepted by the National Medical Products Administration of China (NMPA). Batoclimab continues to progress in clinical trials in other geographies. As of June 30, 2023, the Company’s partners had a total of 305 active programs. There are 29 active programs that have advanced into the clinical stage or later, including three approved drugs, one under regulatory review and 25 in various stages of clinical development.

Second quarter 2023 and recent partner highlights include the following:

Batoclimab

• OmniAb earned milestone revenue related to the advancement of batoclimab into pivotal studies in two additional indications: thyroid eye disease and chronic inflammatory demyelinating polyneuropathy. These indications are in addition to the ongoing Phase 3 study in generalized myasthenia gravis (gMG).
• Harbour BioMed announced the NMPA accepted the Biologics License Application of batoclimab for the treatment of gMG.
• HanAll Biopharma announced it is progressing toward initiation of a Phase 3 clinical study in Japan later this year with batoclimab in gMG.

IMVT-1402

• Immunovant announced it received Investigational New Drug clearance from the U.S. Food and Drug Administration (FDA) for IMVT-1402, a subcutaneously-administered FcRn inhibitor, and initiated a Phase 1 clinical trial in healthy volunteers. This trial will evaluate the safety, tolerability and pharmacodynamics of IMVT-1402. Initial data are expected later this year.

GLS-012

• Gloria Pharmaceuticals initiated a Phase 1/2 study in China to investigate the safety, tolerability and preliminary efficacy of GLS-012 (anti-LAG-3) monotherapy and in combination with GLS-010 in subjects with advanced solid tumors after progression on standard treatment.

CSX-1004

• Cessation Therapeutics announced that the FDA has authorized the company to initiate a clinical trial in the U.S. for CSX-1004, a monoclonal antibody designed specifically to prevent fentanyl overdose. Cessation announced plans to begin trials with the first cohort of subjects in August of 2023.

APVO436

• Aptevo Therapeutics announced that its bispecific acute myeloid leukemia (AML) drug candidate APVO436, in combination with emerging standard-of-care venetoclax and azacitidine, achieved positive duration of remission results in its Phase 1b dose-escalation trial. Aptevo intends to conduct two Phase 2 clinical trials to include relapsed/refractory AML patients beginning in the second half of 2023 and frontline patients beginning in the first half of 2024.

GSK Program-1 (Ion Channels and Transporters)

• OmniAb achieved a research progression milestone for small molecule inhibitors of a genetically-validated target relevant to neurological diseases in collaboration with GSK. Upon this achievement, OmniAb was entitled to a progression milestone payment of $2.0 million.

In May 2023, OmniAb highlighted some of its new technology at the 19th Annual PEGS Boston Conference and Expo, including a presentation on its OmniDeep^™ platform. OmniDeep is a suite of in silico tools for therapeutic discovery and optimization that are woven throughout OmniAb’s various technologies and capabilities. OmniDeep facilitates rapid identification of candidates with the right affinity, specificity and developability profiles to make drug development more effective and efficient.
