On April 3, 2020, resTORbio, Inc. (the Company) issued a press release to announce that it will postpone enrollment in the fifth cohort of its ongoing Phase 1b/2a trial of RTB101, an orally administered, small molecule product candidate that is a potent target inhibitor of rapamycin complex (TORC1), alone or in combination with sirolimus, in Parkinsons disease (PD). The trial is being conducted at clinical sites in New Zealand and the enrollment delay is a consequence of the COVID-19 level 4 alert in New Zealand, where all non-essential services have been closed and people have been instructed to stay home.
Phase 1b/2a Trial of RTB101 alone and in combination with sirolimus in Parkinsons disease study results
The multicenter, 2:1 randomized, double-blind, placebo-controlled Phase 1b/2a trial is evaluating the safety and tolerability of RTB101 alone or in combination with escalating doses of sirolimus (2 mg, 4 mg and 6 mg) once weekly for 4 weeks in patients with Parkinsons disease. To date, patients have been enrolled in four cohorts and dosed once weekly with 300 mg of RTB101 alone, 2 mg of sirolimus alone, a combination of 300 mg RTB101 and 2 mg of sirolimus, or a combination of 300 mg RTB101 and 4 mg of sirolimus. Results of the interim study analysis after the first 3 cohorts indicated that all 3 dosing regimens were well tolerated and RTB101 300 mg once weekly was observed to cross the blood brain barrier. The concentrations of RTB101 in cerebrospinal fluid (CSF) in subjects dosed with RTB101 300 mg once weekly monotherapy were higher than expected and based on preclinical models, have the potential to induce autophagy in the brain. Sirolimus at the dose of 2 mg, alone or in combination with RTB101, was not detected in the CSF. Data from the first three cohorts in the study suggest that the concentrations of RTB101 observed in the CSF four hours after dosing were highest when RTB101 was given as a monotherapy. Enrollment and dosing of the RTB101 300 mg in combination with sirolimus 4 mg once weekly cohort has been completed.
