Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) (“Corbus” or
the “Company”) today announced the completion of subject enrollment
in RESOLVE-1, a Phase 3 study assessing the efficacy and safety of
lenabasum for the treatment of systemic sclerosis (SSc). The
Company expects to report topline results from this study in the
summer of 2020. These data are anticipated to support an initial
marketing application for lenabasum.
“We are grateful to the participants for their
commitment and all our investigators and their staffs for their
dedication and support of the study,” said Barbara White, M.D.,
Chief Medical Officer of Corbus. “Completion of subject enrollment
in this pivotal study is a key milestone to support the potential
filing of a New Drug Application (NDA) in the U.S. and marketing
authorization applications elsewhere.”
RESOLVE-1 has enrolled 365 individuals with SSc
in an international, multicenter, randomized, double-blind,
placebo-controlled study that is being conducted in North America,
Europe, Israel, Japan, South Korea, and Australia. Patients in the
study are randomized 1:1:1 to either receive lenabasum 5 mg twice
per day, lenabasum 20 mg twice per day, or placebo twice per day
for 52 weeks with a follow-up period of 4 weeks.
The primary efficacy endpoint of RESOLVE-1 in
the U.S. is the American College of Rheumatology Combined Response
Index in diffuse cutaneous Systemic Sclerosis (ACR CRISS) score.
The ACR CRISS score is calculated from weighted changes from
baseline in five core outcome measures commonly used to evaluate
treatment effect in trials for SSc: modified Rodnan Skin core
(mRSS), Health Assessment Questionnaire - Disability Index
(HAQ-DI), forced vital capacity (FVC) percent predicted, and
patient and physician global assessments of health related to SSc.
The study is also evaluating multiple secondary endpoints in the
U.S., including changes in HAQ-DI, mRSS and FVC percent predicted.
Additionally, the Company is evaluating the safety and efficacy of
lenabasum in an open-label extension of its Phase 3 study. The
open-label extension enables all the participants in the study to
continue to receive lenabasum following the conclusion of their
trial period.
Lenabasum was granted Orphan Drug Designation
for the treatment of SSc by the U.S. Food and Drug Administration
(FDA) and the European Medicines Agency (EMA) and was granted Fast
Track status by the FDA.
About Lenabasum
Lenabasum is a rationally-designed, oral, small
molecule that selectively binds as an agonist to the cannabinoid
receptor type 2 (CB2). CB2 is preferentially expressed on activated
immune cells, fibroblasts, muscle cells, and endothelial cells. In
both animal and human studies conducted to-date, lenabasum has
induced the production of Specialized Pro-resolving lipid Mediators
(“SPMs”) that activate endogenous pathways which resolve
inflammation and speed bacterial clearance without
immunosuppression. Lenabasum is also believed to have a direct
effect on fibroblasts to limit production of fibrogenic growth
factors and extracellular connective tissue that lead to tissue
fibrosis (scarring). Data from animal models and human clinical
studies suggest that lenabasum can reduce expression of genes and
proteins involved in inflammation and fibrosis. Lenabasum has
demonstrated promising activity in animal models of skin and lung
inflammation and fibrosis in systemic sclerosis (SSc). Lenabasum is
also active in animal models of lung infection and inflammation in
cystic fibrosis and joint inflammation and scarring in rheumatoid
arthritis.
Lenabasum has demonstrated an acceptable safety
and tolerability profiles in clinical studies to date. Lenabasum
treatment was associated with improvement in multiple
physician-assessed and patient-reported efficacy outcomes in Phase
2 studies in patients with diffuse cutaneous SSc and
skin-predominant dermatomyositis. ACR CRISS score was the primary
efficacy endpoint in the Phase 2 study of lenabasum in diffuse
cutaneous SSc and showed a greater treatment effect in subjects who
received lenabasum compared to placebo in that study. Lenabasum
treatment also was associated with a lower rate of and longer time
to pulmonary exacerbations in a Phase 2 cystic fibrosis study.
Additional clinical studies are being conducted and/or planned to
confirm these results and support applications for regulatory
approval.
About Systemic Sclerosis
Systemic sclerosis (SSc), a form of scleroderma,
is a chronic, rare systemic autoimmune disease affecting
approximately 200,000 people in the U.S., EU and Japan.1 SSc
is more common in adults and women than in men and children, and
typically occurs in people aged 30 to 50 years old.2 The
disease is characterized by chronic inflammation, fibrosis (for
example, scarring) and small blood vessel damage in multiple organs
in the body.3 Scleroderma is an autoimmune disease, but it is
unknown why the body's immune system is activated and stays active,
damaging the body's own tissue.4 SSc has the highest mortality rate
among the systemic autoimmune diseases.5 There is no cure for
systemic sclerosis, and there are no FDA-approved treatments for
this disease.6
About Corbus
Corbus Pharmaceuticals Holdings, Inc. is a Phase
3 clinical-stage pharmaceutical company focused on the development
and commercialization of novel therapeutics to treat inflammatory
and fibrotic diseases by leveraging its pipeline of endocannabinoid
system-targeting synthetic drug candidates. The Company's lead
product candidate, lenabasum, is a novel, synthetic, oral,
selective cannabinoid receptor type 2 (CB2) agonist designed to
resolve chronic inflammation and fibrotic processes. Lenabasum is
currently being evaluated in systemic sclerosis, cystic fibrosis,
dermatomyositis, and systemic lupus erythematosus.
Corbus is also developing a pipeline of drug
candidates from more than 600 novel compounds targeting the
endocannabinoid system. The pipeline includes CRB-4001, a 2nd
generation, peripherally-restricted, selective cannabinoid receptor
type 1 (CB1) inverse agonist. Potential indications for CRB-4001
include NASH, among others. Corbus plans to start a Phase 1 study
of CRB-4001 in 2019, intended to be followed by a National
Institutes of Health (NIH)-funded proof-of-concept Phase 2
study.
