• Presented preliminary data on the mechanism of action of Resunab in a clinical research model of inflammation and its resolution in healthy volunteers at the 6th European Workshop on Lipid Mediators; and
• Announced the completion of patient enrollment of Phase 2 clinical study of Resunab in CF.

"We are pleased with the progress we have made over the course of 2016 and our ability to execute a complex clinical development program. We look forward to clinical data from our three current Phase 2 studies," stated Yuval Cohen, Ph.D., Chief Executive Officer of the Company.

Expected Near-Term Milestones

• Report topline data from systemic sclerosis study in Q4 2016;
• Complete dosing in Phase 2 clinical studies for CF in Q4 2016, report topline results of the study in Q1 2017;
• Continue open-label extension study in systemic sclerosis;
• Complete enrollment of Phase 2 clinical study in dermatomyositis in Q2 2017;
• Seek Orphan Drug Designation in Europe for the treatment of systemic sclerosis by the end of 2016;
• Complete additional pre-clinical mechanism of action studies; and
• Launch of the Phase 2 clinical study in patients with SLE expected in H1 2017.

"Moving forward, we continue our commitment to clinically advance Resunab as a potential therapy for individuals with serious inflammatory and fibrotic diseases," concluded Dr. Cohen.

Summary of Financial Results for Third Quarter 2016

For the three months ended September 30, 2016, the Company reported a net loss of approximately $5,347,000, or a net loss per diluted share of $0.12, compared to a net loss of approximately $2,254,000, or a net loss per diluted share of $0.06 for the three months ended September 30, 2015.

For the nine months ended September 30, 2016, the Company reported a net loss of approximately $12,428,000, or a net loss per diluted share of $0.31, compared to a net loss of approximately $6,352,000, or a net loss per diluted share of $0.22 for the nine months ended September 30, 2015.

The increases in the net losses for the three and the nine months ended September 30, 2016 are attributable to increased spending on clinical studies for systemic sclerosis and CF and increased compensation related to increased staffing, bonuses, and stock-based compensation expense.

The Company ended the quarter with approximately $18.9 million of cash and cash equivalents. The Company expects the cash on hand together with the remaining milestone payments of $1,500,000 from the Cystic Fibrosis Foundation Therapeutics, Inc., which the Company expects to receive in the first quarter of 2017, to be sufficient to meet its operating and capital requirements into the fourth quarter of 2017 based on current planned expenditures.

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.
