Norwood, MA, Nov. 10, 2020 (GLOBE NEWSWIRE) -- Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) (“Corbus” or the “Company”), a clinical-stage drug development company pioneering transformative medicines that target the endocannabinoid system (“ECS”), today reported financial results for the third quarter of 2020. The Company also provided clinical, pipeline and corporate updates.

Yuval Cohen, Ph.D., Chief Executive Officer said, “We are emerging from a very challenging period with a continued focus on our lenabasum dermatomyositis program and preclinical pipeline. Our restructuring significantly improved our cash runway, so we can continue to work toward delivering a much-needed novel therapeutic option for patients while also giving us the resources to look at external assets that will be synergistic to our in-house capabilities. We expect our cash runway to be further extended with the cost savings from our plan to shorten the DETERMINE Phase 3 dermatomyositis study to 28 weeks from one year. This decision is driven by recent changes in the dermatomyositis competitive landscape and will accelerate topline data readout to the second quarter of 2021. We see our dermatomyositis program as a potential large value driver for our Company, given that there are about 40,000 dermatomyositis patients in North America and limitations with current treatment options.”

Dr. Cohen continued, “While we were disappointed that both the RESOLVE-1 systemic sclerosis study and the Phase 2b cystic fibrosis study did not meet their primary endpoints, we have a solid understanding of what led to those outcomes. The data generated point to clinical activity associated with lenabasum treatment. The dataset also provided unique insight into disease progression and the impact of current standards of care. With this in mind, we are working with systemic sclerosis and cystic fibrosis experts to further analyze the data and potentially explore paths forward in these programs.”

Clinical Program Updates:

Lenabasum: a novel, oral, selective cannabinoid receptor type 2 (CB2) agonist

     Dermatomyositis – The Phase 3 “DETERMINE” study in dermatomyositis, a rare and life-threatening autoimmune disease characterized by skin and muscle inflammation, is fully enrolled.

Key Updates:

• This double-blind, randomized, placebo-controlled, multinational study enrolled 176 patients, which exceeded the original target of 150 patients. Approximately 60% of patients have completed Week 28 of dosing.
• There have been recent changes in the dermatomyositis competitive landscape with studies that are shorter than one year using the same efficacy endpoint as DETERMINE. Therefore, Corbus will submit a protocol amendment to the FDA and other regulatory agencies to shorten the treatment duration of DETERMINE to 28 weeks from one year. The last subject visit through 28 weeks is expected in March 2021 with topline data to be reported shortly thereafter.
• Baseline patient demographics and disease characteristics were presented at the American College of Rheumatology’s (ACR) Convergence 2020, which took place November 5–9, 2020. ACR poster is available online.
• A separate presentation at ACR Convergence 2020 showed that CB2 expression was increased on immune cells in lesional skin from dermatomyositis subjects in the lenabasum Phase 2 study. Treatment with lenabasum was associated with reduction in immune cell infiltrates, CB2 expression and inflammatory cytokine production in lesional skin from these subjects. ACR poster is available online.
• There is significant unmet need for new medicines to achieve disease control in dermatomyositis because of the limitations of current treatment options. Dermatomyositis affects approximately 80,000 people in North America, EU, and Japan. 

• Systemic Sclerosis – Topline data from the RESOLVE-1 Phase 3 study of lenabasum for the treatment of systemic sclerosis were announced on September 8, and additional data were announced on November 9. RESOLVE-1 was a 52-week, multinational, double-blind, placebo-controlled study that enrolled 365 patients with diffuse cutaneous systemic sclerosis. It was the first large, late-stage clinical study in diffuse cutaneous systemic sclerosis that allowed patients to remain on a wide range of background immunosuppressive therapy.

Key Findings:

• Topline data remain as previously reported.
• Exploratory post-hoc analyses showed lenabasum treatment was associated with a benefit in lung function (forced vital capacity) in subjects on established background immunosuppressant therapies (greater than 2 years).
• Focusing on FVC in patients on established immunosuppressant therapies could address a key unmet need, which Corbus believes represent a potential commercial opportunity.
• Systemic sclerosis is a rare, life-threatening autoimmune disease affecting up to 75K Americans.

Next Steps:

• The Company is continuing to analyze the data and will consider the potential for an additional study based on results of these analyses.
  

• Cystic Fibrosis – Topline data from the CF-002 Phase 2b study of lenabasum for treatment of CF were announced on October 6 and presented at the North American Cystic Fibrosis Conference (NACFC) in October (NACFC Poster #817 available here). CF-002 was a 28-week multinational, double-blind, randomized, placebo-controlled study that dosed 426 subjects who were at high-risk for recurrent pulmonary exacerbations (PEx). It is the first study to enroll subjects who are prone to exacerbation despite being on standard of care, including CFTR modulators.

Key Findings:

• Topline data remain as previously reported.
• Lenabasum did not meet its primary efficacy endpoint in the study.
• Lenabasum was well tolerated with no new safety findings.
• Exploratory post-hoc analyses revealed unexpectedly low PEx rates in subjects from five eastern European countries (21% of total subjects) who received placebo. Pulmonary exacerbations rates in these subjects were 85% lower than in subjects from other countries.
• Exploratory post-hoc analyses in subjects with similar FEV1% predicted at baseline and similar treatment with CFTR-modulators suggested evidence of clinical benefit of lenabasum.
• PEx remains a significant burden in people with CF even with current standard therapies, including antibiotics and CFTR modulators.

Next Steps:

• Further analysis of the data is underway to determine potential next steps. 

• Systemic Lupus Erythematosus (SLE) – The Phase 2b study is ongoing. The study, funded and managed by the National Institutes of Health (NIH), is enrolling at 15 sites in the U.S., with enrollment expected to be completed in the first half of 2021.

Pipeline Updates:

• Corbus has identified several compounds from its CB1 inverse agonist program which the Company believes has more promising physicochemical and pharmacokinetic properties than CRB-4001. The Company is shifting its focus to prioritize development of these compounds and not continuing with CRB-4001. The Company is also looking for attractive external assets that could have a strong synergy with is organizational capabilities, pipeline, and expertise in immunology. Corbus will provide an update at its next R&D day.

Corporate Updates:

• On October 8, Corbus announced a reduction in workforce and restructuring of its operations designed to reduce costs and reallocate resources towards its lenabasum clinical development program in dermatomyositis and systemic lupus erythematosus, as well as the Company’s pipeline of other novel ECS-targeting drug candidates. The restructuring, which included cost reductions, was intended to extend the Company’s cash runway, and, together with the shortening of the DM study to 28 weeks, is designed to extend the Company’s cash runaway beyond the second quarter of 2022.

Financial Results for Third Quarter Ended September 30, 2020:

For the quarter ended September 30, 2020, the Company reported a net loss of approximately $34.9 million or a net loss per diluted share of $0.43, compared to a net loss of approximately $20.8 million or net loss per diluted share of $0.32 for the quarter ended September 30, 2019.

For the quarter ended September 30, 2020, revenue decreased by approximately $1.4 million from the third quarter of 2019 to $1.2 million, due primarily to revenue recognized under the Cystic Fibrosis Program Related Investment Agreement.

Operating expenses for the quarter ended September 30, 2020 increased by approximately $7.5 million to $35.2 million. The increase was primarily attributable to increased clinical trial costs.
Corbus expects its cash and cash equivalents on hand of approximately $81.9 million at September 30, 2020 together with proceeds from the expected final $2.5 million milestone payment from the Cystic Fibrosis Foundation and anticipated foreign tax credits to fund operations and its current clinical plan beyond the second quarter of 2022.
