NORWOOD, Mass., March 12, 2024 (GLOBE NEWSWIRE) -- Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) (“Corbus” or the “Company”), a precision oncology company with a diversified portfolio, today provided a corporate update and reported financial results for the fourth quarter of 2023 and year-ended 2023.

“In 2023 we made significant progress in advancing our pipeline to meaningful milestones. These efforts culminated in us strengthening our balance sheet by raising $116 million of capital in 2024 providing us with a projected runway of over 3 years,” said Yuval Cohen, Ph.D., Chief Executive Officer of Corbus. “The first-in-human CRB-701 dose-escalation data from our development partner, CSPC, was presented at ASCO-GU in January 2024 demonstrating a differentiated safety and PK profile compared to enfortumab vedotin, as well as an emerging efficacy signal in bladder and cervical cancer patients who are Nectin-4 positive. We expect to dose the first patient in our US Ph1 study in March 2024. For CRB-601, the FDA cleared our Investigational New Drug (“IND”) application in January 2024, and we expect to dose the first patient this summer. Finally, for CRB-913, we presented promising pre-clinical data at Obesity Week in October 2023 and are on track to file an IND by the end of 2024,” concluded Dr. Cohen.

Key Corporate and Program Updates:

CRB-701 - a Nectin-4 ADC
CRB-701 (SYS6002) is a next-generation antibody drug conjugate (“ADC”) targeting Nectin-4 that contains a site-specific, cleavable linker and a homogenous drug antibody ratio of 2 using MMAE as the payload. Nectin-4 is a clinically validated, tumor-associated antigen in urothelial cancer.

Encouraging safety and efficacy data from the Ph1 dose-escalation study in China for patients with Nectin-4 positive tumors was presented in January 2024 by CSPC at the 2024 American Society of Clinical Oncology Genitourinary Cancers Symposium (“ASCO-GU”) Poster.

Summary of Ph1 Results:

  • Q3W schedule of CRB-701 (SYS6002) demonstrated a 43% ORR and 71% DCR (n=7) at predicted therapeutically relevant doses (>=2.7mgs/kg).
  • All assessable Nectin-4 positive study participants with mUC or cervical cancer treated at or above this dose demonstrated some level of disease control.
  • No dose limiting toxicities (“DLTs”) were observed to date up to 3.6 mg/kg with further escalation at 4.5 mg/kg ongoing.
  • No cases of peripheral neuropathy or skin rash have been observed to date.

The Company is on track to dose the first patient in the US dose-escalation study by the end of March 2024. The Company expects to provide a clinical update for CSPC’s dose-escalation study in mid-2024 and to present US dose-escalation data by Q1 2025.

CRB-601-TGFβ blocking monoclonal antibody targeting the integrin αVβ8
CRB-601 is a high affinity and selective anti-αvβ8 monoclonal antibody that blocks the activation of TGFβ expressed on cancer cells in the tumor microenvironment. In pre-clinical models, CRB-601 demonstrates enhanced anti-tumor activity when combined with anti-PD-1 checkpoint inhibitor therapy compared to either single agent alone.

In January 2024, the FDA cleared the IND and the Company expects to enroll the first patient in the Ph1 study in the summer of 2024. The Company expects to complete the CRB-601 Ph1 dose-escalation study (monotherapy and in combination with PD-1) by the end of 2024.

CRB-913-CB1 receptor inverse agonist for the treatment of obesity
CRB-913 is a second-generation, highly peripherally restricted CB1 receptor inverse agonist designed to treat obesity. In a diet-induced obesity (“DIO”) mouse model, CRB-913, as a monotherapy and in combination with incretin analogues (tirzepatide, semaglutide, or liraglutide), demonstrates a reduction in body weight in DIO mice and improvements were observed in body fat content, leptinemia, insulin resistance, liver triglycerides, liver fat deposits, and liver histology.

The Company presented CRB-913 pre-clinical data at Obesity Week as an oral presentation and as a late breaking poster in October 2023. The study was also published in Obesity in November 2023. The Company is currently conducting IND enabling studies and expects to file an IND in the fourth quarter of 2024.

$116M of Capital Raised in 2024
In February 2024, the Company closed a public offering raising $94.5 million of gross proceeds and also raised $21.1 million of gross proceeds from ATM sales in January 2024. The Company reported $127 million of cash, cash equivalents, and investments on hand as of February 2, 2024, providing projected cash runway of 3+ years through March 31, 2027.

Dr. Dominic Smethurst Appointed as Chief Medical Officer
In February 2024, the Company appointed Dr. Dominic Smethurst, MA MRCP, as the Company’s Chief Medical Officer (CMO). In this role, Dr. Smethurst is guiding the clinical development of the Company’s clinical pipeline. Dr. Dominic Smethurst has over twenty years of experience working with various pharmaceutical and biotechnology companies and most recently served as CMO of Bicycle Therapeutics, where he helped advance Nectin-4 investigational drugs through early stage and into late-stage development.

Financial Results for Fourth Quarter Ended December 31, 2023
The Company reported a net loss of approximately $8.0 million, or a net loss per diluted share of $1.81, for the three months ended December 31, 2023, compared to a net loss of approximately $10.9 million, or a net loss per diluted share of $2.61, for the same period in 2022. For the year-ended December 31, 2023, the Company reported a net loss of approximately $44.6 million, or a net loss per diluted share of $10.31, compared to a net loss of approximately $42.3 million, or a net loss per diluted share of $10.15 for the same period in 2022.

Operating expenses for Q4 2023 decreased by $0.7 million to approximately $10.1 million for the three months ended December 31, 2023, compared to $10.8 million in the comparable period in the prior year. The decrease was attributable to reductions in compensation expense and legal expenses offset by an increase in development costs for CRB-701 and CRB-601, attributable to moving both drugs into clinical studies in 2024.

The Company reported $20.9 million of cash, cash equivalents, and investments on December 31, 2023, and $127 million on February 2, 2024 after raising $116 million of capital in 2024.
