All such forward-looking statements are based on management’s current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. The use of words such as, but not limited to, “may,” “might,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “intend,” “future,” “potential,” or “continue,” and other similar words or expressions are intended to identify forward-looking statements. Forward-looking statements are neither historical facts nor assurances of future performance.

All statements other than statements of historical facts contained in this presentation, including statements regarding: future results of operations and financial position; business strategy; current and prospective product candidates; ongoing and planned clinical trials and preclinical activities, including the initiation, timing, enrollment, progress and results of our preclinical and clinical studies and our research and development programs; product approvals; research and development costs; current and prospective collaborations; the timing and likelihood of success of our Phase 1b/2a clinical trial of RTB101 alone and in combination with sirolimus in Parkinson’s Disease; the timing or likelihood of regulatory filings and approvals; expectations regarding market acceptance and size; plans for launch and commercialization; plans and objectives of management for future operations; and future results of anticipated product candidates, are forward-looking statements. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties.

Parkinson’s Disease Prevalence: Parkinson’s disease (PD) is the second most common neurodegenerative disease and affects 1% of population over 55 years of age Pathobiology: PD is characterized by loss of >50% of the neurons that produce the neurotransmitter dopamine in a specific area of the brain (substantia nigra) Clinical manifestations: Four cardinal motor symptoms: Resting tremor Bradykinesia (slowed movements) Muscle rigidity Postural instability All current therapies treat symptoms of PD but do not alter disease progression Image from Wikiwand

Slide 15

TORC1 inhibitors may be of therapeutic benefit in Parkinson’s disease Induction of autophagy with a TORC1 inhibitor leads to the clearance of a-synuclein aggregates in a preclinical PD model Malagelada et al.
