Systemic Sclerosis Clinical Program Overview – Late-Stage Clinical Program with Potential Commercialization in 2021

  • Rare and life-threatening autoimmune disease characterized by tissue inflammation and fibrosis;
  • Affects approximately 120,000 people in the U.S., Europe and Japan;
  • Approximately 40% to 60% 10-year mortality;
  • Treatment options for overall disease control limited to immunosuppressive drugs with no drugs currently approved by the FDA for treatment of SSc;
  • Lenabasum was granted Orphan Drug Designation and Fast Track status for the treatment of systemic sclerosis from the FDA and Orphan Designation from the EMA;
  • Enrollment and dosing are ongoing in the Phase 3 study; and
  • Agreement reached with FDA, EMA and Japanese PMDA on design of ongoing study.

The international, multicenter Phase 3 RESOLVE-1 study is a double-blind, randomized, placebo-controlled study assessing the efficacy and safety of lenabasum for the treatment of SSc. The study will enroll approximately 354 subjects at approximately 70 sites in North America, Europe, Israel, Japan, South Korea and Australia. The planned duration of treatment with study drug is 52 weeks. Subjects are randomized 1:1:1 to receive lenabasum 5 mg twice per day, lenabasum 20 mg twice per day or placebo twice per day.

The primary efficacy outcome of the RESOLVE-1 study is change from baseline in modified Rodnan Skin Score ("mRSS"), a measure of skin fibrosis. Secondary efficacy outcomes include change from baseline in patient-reported function and forced vital capacity, as well as the American College of Rheumatology Combined Response Index in diffuse cutaneous Systemic Sclerosis ("ACR CRISS") score, a composite measure of improvement that incorporates change from baseline in mRSS, patient- and physician-reported outcomes and forced vital capacity. These same outcomes were measured in the Phase 2 study and its follow-on OLE study.

Corbus expects to report topline results from the Phase 3 RESOLVE-1 study in the first half of 2020. For more information on the Phase 3 study, please visit ClinicalTrials.gov and reference Identifier NCT03398837.

The Company recently presented safety and efficacy data from the 1-year OLE of the Phase 2 study of lenabasum for the treatment of systemic sclerosis at the Annual European Congress of Rheumatology (EULAR 2018).  Highlights at the time of most recent OLE data-cut include:

  • Safety profile continues to be acceptable with no serious or severe adverse events related to lenabasum and no significant changes from baseline in laboratory safety tests related to lenabasum.
  • At 1-year dosing in the OLE, mRSS improved by a mean of -9.4 points from the start of the Phase 2 double-blind, placebo-controlled phase of the study;
  • At 1-year in the OLE, 77% of subjects achieved improvement in mRSS (reduction ≤ -5 points) that is considered medically meaningful and 50% achieved improvement in mRSS ≤ -10 points;
  • ACR CRISS increased steadily with lenabasum treatment and reached 92% (median), with 50% of subjects achieving a score > 95% at 1-year; and
  • Multiple secondary endpoints continue to improve.

Dermatomyositis Clinical Program Overview – Phase 3 Study to Commence Before Year End

  • Rare and serious autoimmune condition related to SSc and characterized by skin and muscle inflammation;
  • Affects ~80,000 people in the U.S., EU and Japan;
  • 5-year mortality as high as 30%;
  • High unmet medical need. Current standard-of-care treatment includes antimalarial drugs and potent immunosuppressive agents, which can lead to significant side effects;
  • Lenabasum was granted FDA Orphan Drug Designation for the treatment of DM in July 2018; and
  • The Company plans to commence its Phase 3 trial testing the efficacy and safety of lenabasum for the treatment of DM by the end of 2018.  FDA recently provided guidance on the overall study design of this single Phase 3 study at an end-of-Phase 2 meeting.

The international Phase 3 trial will be a 1-year, double-blind, randomized, placebo-controlled study testing efficacy and safety of lenabasum in approximately 150 adults with DM. Subjects will be randomized to receive lenabasum 20 mg twice per day, lenabasum 5 mg twice per day, or placebo twice per day in a 2:1:2 ratio. The primary efficacy outcome will be ACR/ European League Against Rheumatism 2016 Total Improvement Score ("TIS") in myositis, a composite measure of improvement from baseline in six endpoints: Physician Global Activity, Patient Global Activity, Health Assessment Questionnaire, Manual Muscle Testing, muscle enzymes, and extra-muscular activity, which would include skin activity. Change in the Cutaneous Dermatomyositis Activity and Severity Index ("CDASI") activity score will be a secondary efficacy outcome.

The Company recently presented data from the analyses of 6-month OLE data of the Phase 2 study of lenabasum for the treatment of DM at EULAR 2018. Highlights at the time of most recent OLE data-cut include:

  • Safety profile continues to be acceptable;
  • CDASI activity score improved by a mean of -15.4 points from baseline at the start of the Phase 2 double-blind, placebo-controlled phase of the study;
  • 88% of subjects achieved CDASI improvement by at least -5 points, which is considered medically meaningful, 82% achieved improvement of at least -10 points, and 47% achieved a low CDASI activity score (≤ 14 points total score); and
  • Improvement was seen in multiple secondary efficacy endpoints.

Cystic Fibrosis ("CF") Clinical Program Overview – Ongoing Phase 2b study supported by a Development Award for up to $25 million from the Cystic Fibrosis Foundation

  • Life-threatening rare genetic disease that affects ~30,000 patients in the U.S. and ~75,000 patients worldwide;
  • Current average life expectancy for CF patients is approximately 40 years;
  • Pathologic inflammation damages multiple organs including the lungs, impairs organ function, and reduces health-related quality of life;
  • Continued need for drugs to treat pulmonary exacerbations, which are acute episodes of lung inflammation which cause significant decline in respiratory function, high medical costs, and frequently irreversible lung damage;
  • Lenabasum was granted Orphan Drug Designation and Fast Track status for the treatment of CF by the FDA in 2015 and Orphan Drug Status from the European Medicines Agency ("EMA") in 2016; and
  • Enrollment and dosing are ongoing in a Phase 2b study. This Phase 2b study was designed with input from the Therapeutic Development Network of the Cystic Fibrosis Foundation and the European Cystic Fibrosis Society Clinical Trials Network. FDA provided guidance on the overall study design.

The Phase 2b multicenter, double-blinded, randomized, placebo-controlled study will enroll approximately 415 subjects with CF who are at least 12 years of age and at increased risk for pulmonary exacerbations. The primary efficacy outcome is the event rate of pulmonary exacerbations, which is the average number of pulmonary exacerbations per subject per time period. Secondary efficacy outcomes include other measures of pulmonary exacerbations, change in Cystic Fibrosis Questionnaire-Revised Respiratory domain score and change in forced expiratory volume in 1 second (FEV1), % predicted. The study will be conducted in approximately 100 sites across North America, Europe and Australia. Subjects are centrally randomized to one of three cohorts to receive lenabasum 20 mg twice per day, lenabasum 5 mg twice per day, or placebo twice per day for 28 weeks in a 2:1:2 ratio.

Corbus expects to report topline results for the Phase 2b CF study in the first half of 2020.  For more information on the Phase 2 study, please visit ClinicalTrials.gov and reference Identifier NCT03451045.

Systemic Lupus Erythematosus ("SLE") Clinical Program Overview – Represents the Largest Indication Targeted by Lenabasum

  • Prototypical multisystem autoimmune disease in which the innate immune system is chronically activated by immune complexes containing autoantibodies and self-antigens, leading to tissue inflammation and damage;
  • Affects ~300,000 people in U.S. with a 2.4-fold increase in mortality;
  • As with both SSc and DM, patients with SLE continue to have high unmet medical need with current treatments focused on immunosuppressive agents, that can lead to significant side effects; and
  • Enrollment and dosing are ongoing in a first-in-patient Phase 2 randomized, double-blind, placebo-controlled, clinical study evaluating efficacy and safety of lenabasum for the treatment of SLE.  This study is being conducted and funded by the Autoimmunity Centers of Excellence, National Institutes of Health.

The trial will enroll approximately 100 adult SLE patients with active musculoskeletal disease, which is the most common disease manifestation of SLE. Subjects are randomized in a 1:1:1:1 ratio to one of four cohorts to receive placebo or three different doses of lenabasum (5 mg twice per day, 20 mg once per day, or 20 mg twice per day) for 3 months, with 1-month of follow-up. The primary efficacy outcome assesses pain from active musculoskeletal disease, and secondary efficacy outcomes include other assessments of active musculoskeletal disease, overall disease activity using SLE Responder Index, SLE Disease Activity Index ("SLEDAI") and British Isles Lupus Activity Group ("BILAG") scoring systems, and patient-reported outcomes.

Summary of Financial Results for Second Quarter 2018

For the quarter ended June 30, 2018, the Company reported a net loss of approximately $12,100,000 or a net loss per diluted share of $0.21, compared to a net loss of approximately $7,297,000, or a net loss per diluted share of $0.15, for the quarter ended June 30, 2017.

Revenue for the quarter increased by approximately $0.5 million to $0.9 million from the quarter ended June 30, 2017. Revenue recognized in 2018 was related to the up to $25 million Development Award Agreement with the Cystic Fibrosis Foundation that the Company entered into in the first quarter of 2018. Operating expenses for the quarter increased by approximately $5.6 million to $13.2 million due to increased spending for clinical studies, manufacturing costs to produce lenabasum for clinical studies and staffing costs.

The Company received a $6.25 million milestone payment from the Cystic Fibrosis Foundation during the second quarter and ended the quarter with approximately $64.7 million of cash and cash equivalents. The Company expects the current cash and cash equivalents together with the expected milestone payments from the up to $25 million Development Award from the Cystic Fibrosis Foundation to fund operations into the fourth quarter of 2019, based on current planned expenditures.

About Lenabasum

Lenabasum (formerly known as anabasum) is a synthetic, oral, small-molecule, selective cannabinoid receptor type 2 (CB2) agonist that has been shown to preferentially binds to CB2 expressed on activated immune cells and fibroblasts in animal studies. CB2 activation triggers physiologic pathways that resolve inflammation, speed bacterial clearance and halt fibrosis. CB2 activation also induces 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. Through activation of CB2, lenabasum also is believed to have a direct effect on fibroblasts to halt tissue scarring. In preclinical and clinical studies conducted so far, lenabasum has been shown to induce resolution rather than immunosuppression by triggering biological pathways to turn "off" chronic inflammation and fibrotic processes. Lenabasum has demonstrated promising potency in preclinical models of inflammation and fibrosis. Preclinical data and clinical studies to date have shown lenabasum to have a favorable safety, tolerability and pharmacokinetic profile. Data to date suggest that the drug may have clinical benefit as well as a beneficial impact on inflammatory and immunological markers in Phase 2 studies in diffuse cutaneous systemic sclerosis, dermatomyositis and cystic fibrosis. Additional clinical studies are being conducted and/or planned to confirm these preliminary results and support applications for regulatory approval.
