Exhibit 99.1

Corbus Pharmaceuticals Reports Third Quarter 2023 Financial Results and

Provides Corporate Update

•

Data from dose escalation study for CRB-701, a Nectin-4 ADC to treat solid tumors, on track for release in early 2024 along with start of U.S./EU Study

•

IND Submission for CRB-601, an αvβ8 Monoclonal Antibody to treat solid tumors, on track for Q4 2023

•

Pre-clinical data for CRB-913, a peripherally restricted CB1 inverse agonist, published in Obesity and presented at Obesity Week

Norwood, MA, November 7, 2023 (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 third quarter of 2023.

“The third quarter was a productive period for Corbus as data was presented for each of our three programs at relevant scientific conferences” said Yuval Cohen, Ph.D., Chief Executive Officer of Corbus. “We are looking forward to our partners at CSPC sharing the first clinical experience with CRB-701 (SYS6002), a next generation Nectin-4 targeting ADC, in early 2024. This novel ADC comprising of a differentiated monoclonal antibody, proprietary site-specific conjugation cleavable linker, and an MMAE as a payload is designed to provide a stable ADC with significantly less free-circulating MMAE. Pre-clinical data has demonstrated marked differentiation from PADCEV and was presented for the first time at the AACR triple meeting held in October. We also presented two data sets related to CRB-601, our latent TGFb blocking mAb targeting the integrin avb8, at the Society for Immunotherapy of Cancer meeting held in San Diego last week. Finally, we presented the first ever comprehensive data on CRB-913, our highly peripherally restricted cannabinoid type-1 receptor (CB1) inverse agonist. We demonstrated that this orthogonal mechanism of action is active both as a monotherapy and is additive to drugs that target the incretin pathway such as liraglutide, semaglutide, and tirzepatide. Unlike incretin analogs, CRB-913 did not result in loss of lean muscle mass. The data was presented at Obesity Week and coincided with the release of a related manuscript in Obesity the journal” concluded Dr. Cohen.

Key Corporate and Program Updates:

•

CRB-701 next generation Nectin-4 ADC

The Phase 1 clinical trial with CRB-701 targeting Nectin-4 positive solid tumors is recruiting dose level 6 and is ongoing in China. Early clinical experience will be shared in Q1 2024, which will coincide with the initiation of a U.S./EU trial by Corbus. CRB-701 is designed to achieve an improved therapeutic index relative to PADCEV® (SeaGen/Astellas) and will be explored in urothelial cancer and other solid tumors.

Nectin-4 is a clinically validated, tumor-associated antigen in urothelial cancer. The Nectin-4 ADC PADCEV® 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.

The first data characterizing the pre-clinical validation of CRB-701 was presented at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics.

•

The poster, Development of CRB-701 (SYS6002): A novel site-specific Nectin-4 targeting ADC, provided an overview of the pre-clinical development and validation of the differentiating features of CRB-701, including site specific conjugation chemistry, a stable linker that leads to low payload release, and a novel Nectin-4 targeting monoclonal antibody with improved speed of internalization.

•

The pre-clinical safety profile supports dosing at higher ADC exposures relative to enfortumab vedotin (PADCEV®).

The potential of CRB-701 was further highlighted in a “Meet the Expert” webinar hosted by Corbus that featured several notable oncology experts: Daniel P. Petrylak, MD (Genitourinary, Yale School of Medicine), Ari Rosenberg, MD (Head and Neck, University of Chicago), Alexander Spira, MD, PhD, FACP (NSCLC, Virginia Cancer Specialists), and Paraic Kenny, PhD (Breast cancer, Translational Expert, Kabara Cancer Research Institute).

•

CRB-601 Anti- αvβ8 mAb blocking the activation of TGFβ expressed on cancer cells

Corbus presented two posters at the 38th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) held on November 1 - 5, 2023.

•

CRB-601, an integrin αvβ8 blocking antibody entering Phase I: pre-clinical and translational biomarkers for indication selection - which demonstrates anti-tumor activity, immunological changes, and biomarkers of response in mouse models. Results demonstrate the importance of protein detection of the integrin avb8 in selecting disease indications and that in both MC38 and EMT6 models tumor growth inhibition correlated with immune cell penetration into the tumor microenvironment.

•

CRB-601, a selective integrin αvβ8-blocking antibody, prevents TGFβ activation, promotes immune cell remodeling, and exhibits potent antitumor activity – which assessed tumor growth inhibition of CRB-601+/- anti PD-1 in three tumor models, MC38, EMT6, and 4T1. Results showed CRB-601 advances immunotherapeutic strategies by antagonizing integrin αvβ8 and enhancing the efficacy of immune checkpoint inhibitors in vivo. This combination reveals the potential of such synergistic strategies in strengthening anti-tumor immunological responses, thereby emphasizing the promise of this combinatorial approach in advancing the domain of immunotherapy.

The IND submission for CRB-601 is on track for the fourth quarter of 2023.

•

CRB-913 a highly peripherally restricted CB1 inverse agonist for the treatment of obesity

A pre-clinical study was selected for an oral presentation and as a late breaking poster at the 2023 Obesity Week Conference held on October 14-17, 2023. In addition, the study was just published in the November edition of Obesity, the scientific journal of The Obesity Society.

•

In this study, CRB-913, a highly peripherally restricted cannabinoid type-1 receptor (CB1) inverse agonist for the treatment of obesity, was evaluated as monotherapy and in combination with incretin analogs (tirzepatide, semaglutide, or liraglutide) in a diet induced-obesity (DIO) mouse model. CRB-913 demonstrated enhanced plasma exposure and a markedly reduced concentration in the brain compared to the first generation CB1 inverse agonist rimonabant. CRB-913 monotherapy yielded dose-dependent decrease in body weight in DIO mice that was further decreased in combination with tirzepatide, semaglutide, or liraglutide. Concomitantly, improvements were observed in body fat content, leptinemia, insulin resistance, liver triglycerides, liver fat deposits, and liver histology. All changes were statistically significant. Importantly, CRB-913 did not induce loss of lean muscle mass, a harmful phenomenon associated with incretin analogs.

•

The authors of the publication concluded that CRB-913, in combination with incretin analogs, could potentially deliver meaningful improvements in obesity and related conditions.

Financial Results for Quarter Ended September 30, 2023:

The Company reported a net loss of approximately $10.1 million, or a net loss per diluted share of $2.27, for the three months ended September 30, 2023, compared to a net loss of approximately $8.8 million, or a net loss per diluted share of $2.11, for the same period in 2022.

Operating expenses increased by $1.3 million to approximately $9.5 million for the three months ended September 30, 2023, compared to $8.2 million in the comparable period in the prior year. The increase was primarily attributable to manufacturing costs to support the Phase 1 clinical trial material for CRB-601 offset by a reduction in general and administrative compensation expenses. As of September 30, 2023, the company has $28.7 million of cash, cash equivalents and investments on hand.
