• Completed NVG-291 dosing of subjects in Phase 1 clinical trial
• Phase 1b/2a clinical trial of NVG-291 in individuals with spinal cord injury planned to start in Q3 2023
• NVG-291 has been demonstrated in preclinical studies to promote repair mechanisms in the nervous system, including axonal regeneration, remyelination and plasticity

Vancouver, British Columbia--(Newsfile Corp. - February 14, 2023) - NervGen Pharma Corp. (TSXV: NGEN) (OTCQX: NGENF) ("NervGen" or the "Company"), a clinical stage biotech company dedicated to developing innovative solutions for the treatment of nervous system damage, announced that all subjects (male, premenopausal and post-menopausal females) in the Phase 1 clinical trial of the Company's proprietary lead compound, NVG-291, have completed dosing. The Company now plans to initiate a Phase 1b/2a clinical trial of NVG-291 in individuals with spinal cord injury in Q3 2023. Based on the encouraging results from preclinical studies, the Company plans to evaluate the efficacy of NVG-291 versus placebo in two cohorts: individuals with a chronic injury (1-10 years post-injury) and individuals with a subacute injury (10-49 days post-injury). In preclinical studies of spinal cord injury, NervGen's NVG-291 has been demonstrated to promote neural repair mechanisms, including axonal regeneration, remyelination and plasticity.

Bill Radvak, NervGen's Executive Chairman and Interim CEO, stated, "We are delighted to announce the completion of subject dosing in our Phase 1 clinical trial of NVG-291. As we have stated previously, the doses of NVG-291 administered in the multiple dose portion of the study exceed the highest corresponding doses that resulted in significant functional improvements in animal models of acute and chronic spinal cord injury. We now look forward to initiating our Phase 1b/2a clinical trial in spinal cord injury expected by mid-2023."

Dr. Daniel Mikol, NervGen's Chief Medical Officer, noted, "In the final cohorts of the Phase 1 trial, NVG-291 was administered as a once-a-day subcutaneous (i.e., under the skin) injection for 14 days. The safety of subjects was evaluated throughout the treatment phase and through a final scheduled follow-up visit occurring one week after the final dose. While the data from these last male and female cohorts have not yet been unblinded, we can report that, throughout the Phase 1 trial there have been no serious adverse events in subjects receiving NVG-291. We are thrilled to be one step closer to investigating NVG-291 in individuals with spinal cord injury, where we plan to evaluate efficacy using both clinical outcome measures and objective electrophysiological measures that provide information about motor recovery."

About NVG-291

NervGen holds exclusive worldwide rights to NVG-291, a first-in-class therapeutic targeting pathogenic mechanisms that interfere with nervous system repair. NVG-291 is a therapeutic peptide derived from the intracellular domain of the receptor protein tyrosine phosphatase sigma (PTPσ). NVG-291-R, a rodent analog of NVG-291, has been shown to promote nervous system repair and functional recovery in animal models of spinal cord injury, peripheral nerve injury, multiple sclerosis and stroke, through enhanced plasticity, axonal regeneration, and remyelination.
