A Phase 1/2a Study of Oral PRO-1562 in Healthy Subjects and Patients With Relapsing Multiple Sclerosis
11 september 2026 uppdaterad av: Progentos Therapeutics
A Randomized, Double-Blind, Placebo-Controlled Phase 1/2a Trial of PRO-1562 in Healthy Adults and Adults With Multiple Sclerosis and Chronic Optic Neuropathy
Phase 1 will test single oral doses of PRO-1562 in healthy adult subjects to characterize the safety and the amount of drug that is absorbed into the body. Some subjects will have lumbar punctures performed to measure the amount of drug that crosses the blood-brain barrier since that is the site of drug activity.
Phase 2a will be a 6-month trial to test the ability of once monthly dosing of PRO-1562 to promote remyelination of the CNS and provide clinical benefit to adult patients with relapsing multiple sclerosis (RMS) who also have long-term vision problems diagnosed as chronic optic neuropathy. The benefits of remyelination will be measured using tests of visual acuity, speed of optic nerve conduction signals, and clinical assessments of cognitive and motor function. PRO-1562 will be added on to a stable regimen of MS disease modifying therapy.

Detaljerad beskrivning
Phase 1 is a randomized, double-blind, placebo-controlled, single-ascending dose (SAD) trial of PRO-1562 in healthy adult participants at a single clinical research unit to characterize the safety and pharmacokinetics of a range of oral doses of PRO-1562.
Phase 2a is a randomized, double-blind, placebo-controlled, multi-center, 6-month trial of PRO-1562 in adult patients with relapsing multiple sclerosis who also have chronic optic neuropathy.
Patients will remain on their stable regimen of an approved MS disease modifying therapy during the trial.
Oral PRO-1562 or placebo will be dosed once a month at scheduled clinic visits.
Participants will be given the option to continue on their assigned study treatment after completing the 6-month treatment period until the last patient completes the 6-month treatment period.
