Corbus Pharmaceuticals Reports Second Quarter 2023 Financial Results and

Provides Corporate Update

•CRB-701 Phase 1 trial in China is ahead of schedule with dose escalation completion expected Q4 2023 and U.S. clinical trial start planned for Q1 2024

•Preliminary clinical PK data indicates CRB-701 has a longer half-life and reduced levels of circulating free MMAE relative to published data for PADCEV®

•CRB-601 IND submission is on track for Q4 2023

Norwood, MA, August 8, 2023 (GLOBE NEWSWIRE) -- Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) (“Corbus” or the “Company”), a precision oncology company, today provided a corporate update and reported financial results for the second quarter of 2023.

“During the second quarter, substantial progress was made advancing CRB-701, our next generation Nectin-4 antibody drug conjugate (ADC), in-licensed earlier this year from CSPC Pharmaceutical Group (CSPC)” said Yuval Cohen, Ph.D., Chief Executive Officer of Corbus. “Following a recent visit to CSPC in China, we’re pleased to share that the Phase 1 dose escalation in patients with Nectin-4 enriched solid tumors is proceeding well and is currently ahead of the planned schedule. We now anticipate that the dose escalation portion of this trial in China will be completed in Q4 2023. Accordingly, we are accelerating our own development plans for CRB-701, and now anticipate initiating our U.S. clinical trial in Q1 2024 under the currently active US IND. Preliminary clinical data generated to date demonstrates a differentiated pharmacokinetic profile relative to other Nectin-4 targeting agents.”

“Development of our anti-aVb8 mAb CRB-601, is also ongoing and we were pleased to present the latest pre-clinical data for this asset at the AACR 2023 annual meeting in April,” continued Dr. Cohen. “The data that was presented builds upon the robust target engagement previously presented alone and in combination with anti-PD-1. We believe this data reinforces the potential of this new approach in blocking activation of TGFβ locally in the TME. We plan to submit our Investigational New Drug (IND) application for CRB-601 in Q4 2023 and anticipate initiating our Phase 1 clinical trial in the first half of 2024. We note that key competitive programs from Pfizer and AbbVie have progressed to Phase 2 clinical trials, and we see this as supportive evidence that this class of drugs warrant further clinical exploration. It will be a busy 12 months for us, as we continue our evolution into a precision oncology company, and advance both of our programs into the clinic in the US.”

Key Corporate and Program Updates:

•CRB-701 next generation Nectin-4 ADC:

oThe dose exploration of CRB-701 in Nectin-4 positive solid tumors is ahead of schedule. CSPC, our development partner, is enrolling its Phase 1 dose escalation study in China and Corbus now estimates this escalation will be completed by the end of 2023 and plans to initiate an abbreviated Phase 1 in the US in the first quarter of 2024 leveraging the clinical experience from China.

oPreliminary clinical pharmacology data indicates CRB-701 is differentiated from PADCEV® with an increased half-life and reduced levels of circulating free monomethyl auristatin E (MMAE).

oCorbus licensed CRB-701 from CSPC in February 2023 and has exclusive development and commercialization rights in the United States, Canada, the European Union (including the European Free Trade Area), the United Kingdom, and Australia.

oNectin-4 is a clinically validated tumor associated antigen in urothelial cancer. The Nectin-4 ADC PADCEV® (SeaGen/Astellas) is approved for use in late metastatic urothelial cancer and recently received an expanded label from the Food and Drug Administration based on accelerated approval for use in combination with KEYTRUDA® for patients with locally advanced or metastatic urothelial carcinoma who are ineligible for cisplatin-containing chemotherapy.

oCRB-701 is designed to achieve an improved therapeutic index and will be explored in urothelial cancer, as well as a range of other Nectin-4 expressing solid tumors.

oCRB-701 has key features that support a differentiated profile including a novel Nectin-4 antibody and a site-specific conjugation linker that results in faster ADC internalization, longer half-life, and reduced payload release in plasma. Pre-clinical and dose escalation data demonstrates the potential to achieve higher exposures with CRB-701 resulting in an opportunity to improve the therapeutic index.

•CRB-601 blocking the activation of TGFβ

oCRB-601 is a potent and selective anti-αvβ8 integrin monoclonal antibody (mAb) designed to block the activation of latent TGFβ within the tumor micro-environment (TME). CRB-601 significantly inhibits tumor growth as a monotherapy in murine models and enhances the efficacy of anti-PD-1 immunotherapy as a combination in checkpoint inhibitor (CPI) sensitive and CPI-resistant tumor models.

oCorbus presented pre-clinical data at the American Association of Cancer Research (AACR) 2023 annual meeting indicating that CRB-601 exhibited dose dependent tumor growth inhibition (TGI) in the EMT6 tumor model which was significantly augmented in combination with anti-PD-1 therapy. These effects were associated with changes in TME immune cell populations with marked increases in infiltrating T cells, NK cells and M1 polarized macrophages. Efficacy correlated with cell surface αvβ8 occupancy by CRB-601. CRB-601 treatment downregulated phosphorylation of SMAD proteins, pSMAD2 and pSMAD3, consistent with blockade of the TGFβ signaling pathway.

oThe IND submission for CRB-601 is anticipated in Q4 2023, and the Company expects to enroll the first patient in its Phase 1 study in the first half of 2024.

oWe note that recent events from other development programs of mAb with a similar mechanism of action including those of Pfizer and AbbVie indicate their advancement into Phase 2 clinical trials.

Financial Results for Quarter Ended June 30, 2023:

The Company reported a net loss of approximately $8.8 million, or a net loss per diluted share of $2.05, for the three months ended June 30, 2023, compared to a net loss of approximately $13.2 million, or a net loss per diluted share of $3.18, for the same period in 2022.

Operating expenses decreased by $4.1 million to approximately $8.2 million for the three months ended June 30, 2023, compared to $12.3 million in the comparable period in the prior year. The decrease was primarily attributable to a litigation settlement payment of $5.0 million in 2022 and reduction in general and administrative expenses in the current period offset by increases in product development expenses for CRB-701 and CRB-601.

As of June 30, 2023, the company has $36.6 million of cash, cash equivalents and investments on hand which is expected to fund operations through the second quarter of 2024, based on the current planned expenditures.
