Corbus Pharmaceuticals Announces Last Subject Enrolled in Phase 2 Study of Resunab for the Treatment of Cystic Fibrosis

Phase 2 Study to Be Completed Before Year End; Top-Line Data Expected in Early Q1 2017

NORWOOD, MA--(Marketwired - September 12, 2016) - Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) ("Corbus" or the "Company"), a clinical stage drug development company targeting rare, chronic, serious inflammatory and fibrotic diseases, announced today that it has completed subject enrollment in its Phase 2 clinical study of Resunab for the treatment of cystic fibrosis ("CF"). The Company expects to report top-line results from this study early in the first quarter of 2017. The international, multi-center, double-blinded, randomized, placebo-control trial is supported by a $5 million development award from the Cystic Fibrosis Foundation.

The objectives of the study are to evaluate Resunab's safety, tolerability and efficacy in adults with CF, without regard to underlying genetic mutation or infecting pathogen. Study subjects are being treated with Resunab daily for a period of 84 days, with a follow-up period of 28 days. Efficacy outcomes include lung function as measured by forced expiratory volume in 1 second (FEV1) and patient-reported symptoms. Additionally, Resunab's impact on sputum microbiota and biomarkers of inflammation in sputum and blood will be assessed.

"Resunab's intended pharmacological activity is resolution of chronically activated innate immune responses including tissue inflammation and fibrosis. This novel mechanism of action is expected to reduce airway obstruction and, ultimately, lung destruction over time in CF," stated Barbara White, M.D., Chief Medical Officerof the Company.

James Chmiel, M.D., M.P.H. is Professor of Pediatrics, Case Western Reserve University, Associate Director of the LeRoy W. Matthews Cystic Fibrosis Center at University Hospitals Rainbow Babies and Children's Hospital in Cleveland, and principal investigator for the trial in the United States. Dr. Chmiel commented, "Inflammation causes lung damage in CF, and none of the approved treatments for CF directly address this aspect of the disease. By activating the resolution phase of inflammation, Resunab has the potential to provide a clinical benefit not being offered by the current medications for CF."

Yuval Cohen, Ph.D., Chief Executive Officer of the Company, commented, "We are pleased to have achieved this important clinical milestone for Resunab and will complete this trial before year's end, with top-line data readout expected early in the first quarter of 2017. We are grateful to the individuals and physicians who have participated in the study and to the Cystic Fibrosis Foundation for its support."

Resunab was granted Orphan Drug Designation and Fast Track status for the treatment of CF from the U.S. Food and Drug Administration ("FDA") in 2015. Resunab is currently being evaluated in three separate Phase 2 clinical studies in CF, diffuse cutaneous systemic sclerosis ("systemic sclerosis"), and skin-predominant dermatomyositis. Top-line data from the systemic sclerosis study is expected to be reported in the fourth quarter of 2016, for the CF study in the first quarter of 2017, and for dermatomyositis study in the second half of 2017. A clinical study of Resunab in the treatment of systemic lupus erythematosus ("SLE") is planned for the first half of 2017.

About Cystic Fibrosis

Cystic Fibrosis ("CF") is a chronic, life-threatening, genetic disease caused by inheriting two dysfunctional CFTR genes that normally regulate salt and water movement across cells in the respiratory and digestive systems. CF affects approximately 30,000 patients in the U.S and 75,000 patients worldwide. People with CF have thick, sticky mucus that clogs their airways, with recurrent bacterial infections and chronic inflammation in their lungs. In the gastrointestinal tract, they also have mucus accumulation, bacterial overgrowth, and inflammation. The dysfunctional CFTR genes cause an exaggerated inflammatory response that compounds the damage from a coexisting infection in the lungs and gut. CF results in destruction of lung tissue, lung fibrosis, pancreatic insufficiency, CF-related diabetes, malabsorption, malnutrition, growth retardation, and liver disease, including cirrhosis. The harmful inflammation and accompanying fibrosis in CF damages multiple organs, impairs organ function, reduces health-related quality of life, and can lead to death.

About Resunab

Resunab is a novel synthetic oral endocannabinoid-mimetic drug that preferentially binds to the CB2 receptor expressed on activated immune cells and fibroblasts. CB2 activation triggers endogenous pathways that resolve inflammation and halt fibrosis. Preclinical and Phase 1 studies have shown Resunab to have a favorable safety, tolerability and pharmacokinetic profile. It has also demonstrated promising potency in preclinical models of inflammation and fibrosis. Resunab is designed to trigger the production of "Specialized Pro-resolving Lipid Mediators" that activate an endogenous cascade responsible for the resolution of inflammation and fibrosis, while reducing production of multiple inflammatory mediators. Resunab has direct effects on fibroblasts to halt tissue scarring. In effect, Resunab triggers endogenous pathways to turn "off" chronic inflammation and fibrotic processes, without causing immunosuppression.

About Corbus
