Phase 3 trial: Parkinson's pill solengepras cuts 'off' time by about 37 minutes a day

A 341-patient phase 3 trial of solengepras, a once-daily pill that blocks the GPR6 receptor rather than acting on dopamine, found the higher dose gave about 37 minutes less daily 'off' time than placebo. Developer Cerevance plans to talk to regulators, and the pill could be available in two to three years.

The story, neutrally told

Mixed · 2A once-daily pill for Parkinson's disease called solengepras reduced the time patients spent in 'off' periods, when they feel stiff, slow or shaky, in a late-stage trial. Mixed · 2The randomised, double-blind, placebo-controlled trial involved 341 people with Parkinson's in the US, Europe, the UK and Australia. They received 75mg or 150mg of solengepras, or a placebo, once a day for 12 weeks, and continued taking their dopamine-based drugs. Mixed · 2Both the solengepras and placebo groups improved. The higher-dose group had about 37 minutes less 'off' time a day than the placebo group, and about 94 minutes less than before the trial began.

Mixed · 2The higher-dose group also gained about 36 extra minutes a day of 'on' time without troublesome dyskinesia compared with placebo. Patients did better on a scale of everyday activities such as dressing and eating, and reported less daytime sleepiness and better quality of life. Mixed · 2The drug appeared well tolerated, with no serious side effects reported. The Independent said some people had headaches and urinary tract infections. The Daily Mail said 3.5 per cent of patients stopped treatment because of side effects, the same share as on placebo. Mixed · 2Most current Parkinson's drugs, such as levodopa, boost or mimic dopamine, and they can cause involuntary movements (dyskinesia), nausea and hallucinations. Solengepras instead blocks a receptor called GPR6 in a brain circuit that acts as a brake on movement.

Mixed · 2Cerevance, the Boston-based company that developed the drug, will discuss the results with the US Food and Drug Administration, with UK regulator talks expected to follow. The pill could potentially be available within two to three years. Mixed · 2Cerevance chief executive Craig Thompson described a consistent pattern of benefit and called solengepras a potential first-in-class non-dopaminergic therapy. Dr Stuart Isaacson, a principal investigator, said it 'gives great hope for the future'. Laurence Barker of SV Health Investors, a Cerevance board member, called it the first positive phase three study for a non-dopaminergic mechanism for a very long time. Mixed · 2About 166,000 people in the UK have been diagnosed with Parkinson's. The Independent adds that more than 10 million people live with it worldwide.

Every sentence links to the reporting it rests on. The pill in front of each says where its sources sit: Left, Centre or Right when one side supplies at least half of them, Mixed when they are evenly split. The number is how many outlets it cites.
