Frequently asked questions about NVG-291

What is NVG-291 used for?

NVG-291 is an investigational small molecule being developed for spinal cord injury. It is being studied in patients with chronic and subacute spinal cord injuries. The drug is currently in Phase 1 clinical development and has not been approved by the FDA.

Who makes NVG-291?

NVG-291 is being developed by NervGen Pharma Corp., a biopharmaceutical company. The company's stock is listed under the ticker symbol NGEN. NervGen is conducting clinical trials to evaluate the safety and efficacy of NVG-291 in spinal cord injury.

What phase is NVG-291 in?

NVG-291 is in Phase 1 clinical development. It has completed two Phase 1 trials, one in healthy adults and one in subjects with spinal cord injury. The drug has received Fast Track and Orphan Drug designations from the FDA, but it is not yet approved.

What clinical trials is NVG-291 in?

NVG-291 has been studied in two completed Phase 1 trials. NCT05308953 was a safety study in 74 healthy adults in Australia. NCT05965700 evaluated NVG-291 in 24 subjects with spinal cord injuries in the United States. Both trials are now completed.

Is NVG-291 FDA approved?

NVG-291 is not FDA approved. It is an investigational drug currently in Phase 1 clinical trials. The FDA has granted NVG-291 Fast Track and Orphan Drug designations for spinal cord injury, which are intended to expedite development and review, but approval has not been granted.

Is NVG-291 the same as other drugs?

NVG-291 is a distinct investigational small molecule developed by NervGen Pharma Corp. It is not known to be the same as any other approved drug. Its mechanism of action is not publicly detailed in the available information, and it is being studied specifically for spinal cord injury.
