Parkinson’s Disease: Levodopa-induced dyskinesia Neurodegenerative Diseases


SLIDE 17

Advantage of PD as a clinical indication for TORC1 inhibitors: levodopa-induced dyskinesia (LID) is a potential clinical endpoint that can be assessed in a shorter time frame than disease progression LID is a disabling side effect of chronic levodopa treatment associated with significantly impaired quality of life and increased health care costs1 Most common dyskinesias: chorea (jerky involuntary movements, especially around the face, shoulders, and hips) dystonia (involuntary muscle contraction leading to twisting, repetitive movements, or abnormal posture in affected muscle or muscle group) Average time to onset of dyskinesia estimated at 6.5 years1 > 90% of PD patients will have LID after 15 years of levodopa therapy3 1 and figure Calabresi et al., 2010; 2 Tran et al., 2018; 3 Ahlskog and Muenter 2001 and Hely et al 2005

Multiple pathways implicated in levodopa-induced dyskinesia (LID) pathogenesis converge on ERK and downstream TORC1 hyperactivation TSC TORC1 Dyskinesia Adapted from Calabrisi P et al., Lancet Neurol, 2010 Santini et al. Sci Signaling, 2009 Medium Spiny Neuron 4EBP1 S6K


SLIDE 19

TORC1 is hyperactivated in medium spiny neurons in preclinical PD models of LID and TORC1 inhibition alleviates LID A: Administration of levodopa in a mouse model of PD (unilateral 6-OHDA lesion) led to hyperactivation of TORC1(as assessed by pS6 levels) in medium spiny neurons and development of dyskinesia. B: Rapamycin inhibited TORC1 activation and ameliorates dyskinesia, as assessed by an abnormal involuntary movement score (AIMs), determined by an observer blind to treatment assignment. ooo,*** P<0.001 versus untreated control.

Interim data from three cohorts in the Phase 1b/2a study demonstrate that RTB101 is well tolerated, crosses the blood brain barrier, and reaches concentrations in cerebrospinal fluid observed in preclinical models to inhibit the activity of TORC1 and induce autophagy in neuronal cells —

 

   

TORC1 Inhibition in the brain with RTB101 may offer a new treatment paradigm for multiple neurodegenerative diseases associated with the accumulation of protein aggregates, such as Parkinson’s, Huntington’s and Alzheimer’s disease —

Boston, MA, Feb 19, 2020 – resTORbio (Nasdaq: TORC) today announced interim results from the ongoing Phase 1b/2a trial of RTB101, an orally-administered small molecule potent target of rapamycin complex 1 (TORC1) inhibitor product candidate, alone or in combination with sirolimus, in Parkinson’s disease (PD).

“We are pleased to have observed that RTB101 is well tolerated and crosses the blood brain barrier in Parkinson’s disease patients at concentrations that have the potential to induce autophagy, the process by which cells break down toxic misfolded protein aggregates. Preclinical data suggest that induction of autophagy has the potential to slow the progression not only of Parkinson’s disease but also of multiple other neurodegenerative diseases that are characterized by the accumulation of toxic protein aggregates in cells such as Huntington’s and Alzheimer’s disease,” said Dr. Joan Mannick, Co-Founder and Chief Medical Officer of resTORbio.

Phase 1b/2a Trial of RTB101 alone and in combination with sirolimus in Parkinson’s disease interim 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 Parkinson’s disease. To date, patients have been enrolled in three cohorts and dosed once weekly with 300 mg of RTB101 alone, 2 mg of sirolimus alone, or a combination of 300 mg RTB101 and 2 mg of sirolimus. Results of the interim study analysis 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 of the RTB101 300 mg in combination with sirolimus 4 mg once weekly cohort is ongoing.

Corporate Update    

The company has initiated a process to evaluate external opportunities, such as partnerships, acquisitions, mergers and other financial and strategic alternatives to maximize shareholder value. The company has engaged JMP Securities LLC to act as a strategic advisor for this process. There can be no assurance that this strategic review process will result in the company pursuing any transaction or that any transaction, if pursued, will be completed.

About Parkinson’s Disease

Parkinson’s disease (PD) is a progressive neurodegenerative disease that affects approximately 7.5 million people worldwide. The incidence of PD increases rapidly in people 60 years of age and older, with a mean age at diagnosis of 70.5 years. Inhibition of TORC1 has been shown in multiple preclinical models to ameliorate neurodegenerative diseases including Parkinson’s disease. TORC1 inhibition with RTB101 alone or in combination with sirolimus, may provide a therapeutic benefit to PD patients by ameliorating levodopa-induced dyskinesia and/or by inducing autophagy which leads to the breakdown of protein aggregates and improved neuronal survival.


About RTB101

RTB101 is an oral, selective, and potent TORC1 inhibitor product candidate that inhibits the phosphorylation of multiple targets downstream of TORC1. Inhibition of TORC1 has been observed to extend lifespan and healthspan in aging preclinical species and to improve the function of aging organ systems, including neurologic function, suggesting potential benefits in several aging-related diseases.

About resTORbio
