Corbus Pharmaceuticals Reports First Quarter 2023 Financial Results and Provides Corporate Update
- Company expanded precision oncology pipeline with in-licensing of CRB-701: a clinical-stage Nectin-4 antibody drug conjugate (ADC) from CSPC Pharmaceutical Group
- CRB-701 Phase 1 dose escalation study ongoing in patients with advanced solid tumors in China
- Presented latest CRB-601 anti-αvβ8 mAb pre-clinical data at American Association of Cancer Research (AACR) 2023 annual meeting with IND submission on track for the second half of 2023
- Expanded Board of Directors with appointment of Yong Ben, MD
NORWOOD, Mass., May 9, 2023 /PRNewswire/ -- 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 first quarter of 2023.
"During our first quarter we continued our evolution into a precision oncology company, led by the execution of our exclusive licensing agreement for CRB-701, a next generation Nectin-4 ADC," said Yuval Cohen, Ph.D., Chief Executive Officer of Corbus. "We are excited about the potential of this differentiated clinical stage asset that targets Nectin-4 enriched tumors. We also presented additional pre-clinical data at AACR 2023 annual meeting on CRB-601, demonstrating robust target engagement associated with anti-tumor activity 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 look forward to advancing both CRB-701 and CRB-601 and potentially delivering on a number of milestones in 2023."
Key Corporate and Program Updates:
- CRB-701 next generation Nectin-4 ADC:
- Licensed CRB-701 from CSPC Pharmaceutical Group with exclusive development and commercialization rights in the United States, Canada, the European Union (including the European Free Trade Area), the United Kingdom, and Australia.
- Nectin-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.
- CRB-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.
- CRB-701 has key features that support a differentiated profile including site-specific conjugation linker chemistry that results in low payload release in plasma and a novel Fc-enabled antibody with an improved pharmacokinetic profile. Pre-clinical data demonstrates the potential to achieve higher exposures with CRB-701 resulting in an improved therapeutic index.
- Clinical development is underway and will focus on Nectin-4 positive tumors, including urothelial cancer. CSPC has commenced a Phase 1 dose escalation study in China for patients with advanced solid tumors. Corbus plans to bridge data from this Phase 1 trial to support a U.S. clinical trial starting in mid-2024.
- CRB-601 blocking the activation of TGFβ
- CRB-601 is a potent and selective anti-αvβ8 integrin monoclonal antibody designed to block the activation of latent TGFβ within the tumor micro-environment (TME). CRB-601 significantly inhibits tumor growth as monotherapy and enhances the efficacy of anti-PD-1 immunotherapy as a combination in checkpoint inhibitor (CPI) sensitive and CPI-resistant tumor models.
- IND submission for CRB-601 is on track for the second half of 2023. The Company expects to enroll the first patient in the Phase 1 study by the end of 2023.
- Corbus presented pre-clinical data at the 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-PD1 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.
- Corbus hosted the first in the series of virtual "Meet the Expert" events titled "Blocking TGFβ with CRB-601—a New Play for an Old Target," on April 25th. The event featured Jeffrey Clarke, MD (Duke University School of Medicine) and Joan Seoane, PhD (Vall d'Hebron Institute of Oncology) who discussed the challenges and potential opportunities in targeting Transforming Growth Factor β (TGFβ) in oncology. A replay of the webinar is available from the events page of the Corbus website here.
Addition to the Board:
- Dr. Yong Ben joined the Corbus Board of Directors on March 1, 2023. Dr. Ben is an oncology researcher and pharma industry executive, with multiple drug approvals to his credit. He is currently a venture partner at Eight Roads Venture (formerly known as Fidelity Ventures). He was formerly the Chief Medical Officer of BeiGene, Ltd. and BioAtla, Inc., and led the clinical development of the Immuno-Oncology portfolio for AstraZeneca PLC. This appointment augments our Board with his extensive oncology experience both in the United States and China.
Financial Results for Quarter Ended March 31, 2023:
The Company reported a net loss of approximately $17.7 million, or a net loss per diluted share of $4.24, for the three months ended March 31, 2023, compared to a net loss of approximately $9.4 million, or a net loss per diluted share of $2.26, for the same period in 2022.
Operating expenses increased by $8.8 million to approximately $17.3 million for the three months ended March 31, 2023, compared to $8.5 million in the comparable period in the prior year. The increase was primarily attributable to the upfront payment of $7.5 million associated with the CSPC License Agreement, $1.2 million associated with the achievement of a development milestone under the USCF License Agreement, and higher drug manufacturing costs offset by reductions in general and administrative expenses associated with legal costs, stock-based compensation expense, and insurance policies.
As of March 31, 2023, the company has $44.2 million of cash and investments on hand which is expected to fund operations through the second quarter of 2024, based on the current planned expenditures.
