NORWOOD, Mass., March 7, 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 fourth quarter and year-end of 2022.

"The fourth quarter and recent weeks have been a productive period for Corbus as we continue to evolve into a precision oncology company," said Yuval Cohen, Ph.D., Chief Executive Officer of Corbus. "With the execution of our exclusive licensing agreement for CRB-701, a next generation Nectin-4 ADC, we are excited to have a compelling, differentiated asset in the clinic. Concurrently, we continue on-track to the clinic with CRB-601 supported by our latest pre-clinical data presented at SITC 2022".

Key Corporate and Program Updates:

• CRB-701 next generation Nectin-4 ADC
  
  
• Acquired CRB-701 through licensing agreement with CSPC Pharmaceutical Group granting exclusive development and commercialization rights in the United States, Canada, the European Union (including the European Free Trade Area), the United Kingdom, and Australia.
  
  
• CRB-701 is designed to achieve an improved therapeutic index and patient convenience and could act on a broad range of Nectin-4 expressing tumors.
  
  
• Clinical development is underway and will focus on urothelial cancer and other Nectin-4-positive solid tumors potentially including lung, breast and prostate cancer.
  
  
• 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 microenvironment.
  
  
• CRB-601 significantly inhibits tumor growth as a single agent and enhances the efficacy of anti-PD-1 immunotherapy in checkpoint inhibitor (CPI) sensitive and CPI-resistant tumor models.
  
  
• Pre-clinical data presented at SITC 2022 indicate that anti-tumor activity of CRB-601 as a monotherapy correlates with protein expression of αvβ8. CRB-601 is scheduled for IND submission in the second half of 2023 in solid tumor cancer patients with the first patient treated by the end of 2023.
  
  
• Additions to the Board and Management Changes

We thank him for his efforts and leadership and wish him well in his future endeavors", stated Yuval Cohen Ph.D., Chief Executive Officer of Corbus.

Financial Results for Fourth Quarter Ended December 31, 2022:

The Company reported a net loss of approximately $10.9 million, or a net loss per diluted share of $2.61, for the three months ended December 31, 2022, compared to a net loss of approximately $10.3 million, or a net loss per diluted share of $2.46, for the same period in 2021.  For the year ended December 31, 2022, the Company reported a net loss of approximately $42.3 million, or a net loss per diluted share of $10.15, compared to a net loss of approximately $45.6 million, or a net loss per diluted share of $11.15 for the same period in 2021.

Operating expenses for Q4 2022 increased by $0.8 million to approximately $10.8 million for the three months ended December 31, 2022, compared to $10.0 million in the comparable period in the prior year. The increase was primarily attributable to pre-clinical costs to support IND filing for CRB-601 offset by decreased clinical trial and drug manufacturing costs, as well as an overall reduction in compensation expense. A reverse stock split of 1-for-30 was effected on February 14, 2023 and all per share amounts except the authorized shares have been retroactively adjusted to reflect the reverse split.

As of December 31, 2022, the Company has $59.2 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.
