- Completed Enrollment of Dose Escalation Part of Phase 1 Clinical Trial of its Next-Generation Nectin-4 Targeting ADC (CRB-701) - First data expected to be presented in Q1 2025
- Presented New CRB-913 Pre-Clinical Data at Obesity Week 2024 - Phase 1 Trial Expected to Commence in Q1 2025
"We continue to make steady and significant progress across our pipeline,” said Yuval Cohen, Ph.D., Chief Executive Officer of Corbus. "We expect to report the first data from the CRB-701 U.S. bridging study in Q1 2025. This significant dataset will build on the encouraging clinical data presented at ASCO 2024 by CSPC, our development partner. The emerging efficacy and safety data presented at ASCO 2024 was promising and demonstrated the drug is clinically active with a differentiated safety profile.”
"We are also pleased with the continued development of CRB-913, our highly peripherally restricted CB1 inverse agonist for the treatment of obesity. We presented updated pre-clinical data at Obesity Week 2024 and expect to dose the first study participant in Q1 2025,” concluded Dr. Cohen.
Key Corporate Updates
CRB-701:
CRB-701 (SYS6002) is a next-generation ADC targeting Nectin-4 that contains a site-specific, cleavable linker and a precise drug antibody ratio of 2 using MMAE as the payload.
- The Company completed enrollment of the dose escalation part of its bridging Phase 1 clinical trial of CRB-701 (SYS6002) (NCT06265727) that is being conducted in the U.S. and Europe. The three-part Phase 1 trial is evaluating the safety, pharmacokinetics and efficacy of CRB-701 in patients with advanced solid tumors known to be associated with high Nectin-4 expression. The Company expects to report the first data from the dose escalation study in Q1 2025, which will be the first Western data and provide a translational bridge to the encouraging Chinese data presented by our development partners, CSPC, at ASCO 2024. That data, based on 37 patients, demonstrated:
- 44% ORR and 78% DCR in metastatic urothelial cancer ("mUC”) and 43% ORR and 86% DCR in cervical cancer to date at doses ≥ 1.2mg/Kg.
- No dose limiting toxicities ("DLTs”) have been observed to date in doses up to and including 4.5 mg/Kg.
- Three cases of skin rash (including one grade 3) and one case of grade 1 neuropathy seen to date; all were resolved.
CRB-913 is a second-generation highly peripherally restricted CB1 receptor inverse agonist designed to treat obesity.
- The Company continues to conduct IND-enabling studies on CRB-913 and expects to dose the first patient in a Phase 1 study in Q1 2025.
- The Company presented new pre-clinical data (Poster Presentation) at Obesity Week 2024. Key findings include:
- Levels of CRB-913 in the brain were 15-fold lower than monlunabant in lean mice.
- Dose-response demonstrated for a range of 5 to 80 mg/Kg/day achieving up to 38% weight loss in diet-induced obesity ("DIO”) mice.
- Semaglutide treatment followed by its replacement with CRB-913 demonstrated continued weight loss in DIO mice.
- Switching from semaglutide to CRB-913 led to a doubling of fat loss in DIO mice.
CRB-601:
CRB-601 is a potentially best-in-class 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.
- The Company expects to dose the first patient in Q4 2024 for the Phase 1 portion of the CRB-601 clinical study NCT06603844 for the treatment of patients with advanced solid tumors.
The Company reported a net loss of approximately $13.8 million, or $1.15 per diluted share, for the three months ended September 30, 2024, compared to a net loss of approximately $10.1 million, or $2.27 per diluted share for the same period in 2023.
Operating expenses increased by $6.0 million to approximately $15.5 million for the three months ended September 30, 2024, compared to $9.5 million in the comparable period in the prior year. The increase was primarily attributable to an increase of $3.2 million in CRB-701 clinical trial costs with our contract research organization ("CRO") and clinical sites, IND-enabling studies for CRB-913 of $1.0 million and higher compensation costs of $1.6 million mainly due to stock-based compensation expense.
As of September 30, 2024, the Company had $159.4 million in cash, cash equivalents and investments on hand, which is expected to fund operations through Q3 2027, based on the current planned expenditures. During the third quarter of 2024, the Company raised $35.6 million of net proceeds pursuant to the Company's ATM program by issuing 663,730 shares. In addition, on August 1, 2024, the Company's made a final $11.8 million loan payment and the loan has been fully paid off.
