“The advancements throughout our portfolio in recent months exemplify the potential of an unwavering team and an operational backbone that allows us to efficiently move a diverse set of programs forward in multiple CNS indications,” said
Recent Business Highlights and Upcoming Milestones:
Psychiatry
- Praxis expects topline results from the ongoing
PRAX -114 Phase 2/3, placebo-controlled Aria Study for monotherapy treatment of Major Depressive Disorder (MDD) in the first half of 2022. The Aria Study is intended to serve as one of two trials required by theU.S. Food and Drug Administration (FDA) to demonstrate clinical efficacy to support registration ofPRAX -114 for monotherapy treatment of MDD. - The Company expects topline results from the ongoing
PRAX -114 Phase 2, placebo-controlled, dose-ranging Acapella Study in the first half of 2022. The Acapella Study is intended to provide additional understanding of the dose range and to evaluate the safety and efficacy ofPRAX -114 at doses of 10, 20, 40 and 60 mg, primarily in adjunctive MDD participants. - Following the announcement of positive topline results from the
PRAX -114 Phase 2a, proof-of-concept trial for treatment of perimenopausal depression, Praxis plans to continue investigation ofPRAX -114 for treatment of women with menopausal and mood symptoms in a Phase 2b trial. Plans for the Phase 2b trial will be disclosed in the fourth quarter of 2021. - Praxis plans to initiate a
PRAX -114 Phase 2, placebo-controlled study for treatment of post-traumatic stress disorder (PTSD) in the fourth quarter of 2021. Topline results are expected in the second half of 2022. The trial is designed to evaluate the safety, tolerability and efficacy of a nightly dose of 40 mg ofPRAX -114 for 4 weeks in approximately 80 participants with PTSD, using the CAPS-5 total score as the primary endpoint.
Movement Disorders
- The Company has completed dosing in a two-part
PRAX -944 Phase 1 study to explore a faster titration regimen. Topline results are expected in the fourth quarter of 2021. The Phase 1 study is designed to evaluate the safety, tolerability and pharmacokinetics (PK) of titratingPRAX -944 up to 120 mg in a 10-day regimen in participants aged 18 to 54 years (Part A) and 55 to 75 years (Part B). - Praxis is currently in the second of two cohorts of its
PRAX -944 Phase 2a trial for treatment of essential tremor (ET), evaluating safety and efficacy in patients titrated up to 120 mg per day. Preliminary open-label safety, tolerability and efficacy data is expected in the fourth quarter of 2021, followed by complete open-label and placebo-controlled, randomized withdrawal results in the first half of 2022. - Praxis initiated the
PRAX -944 Phase 2b Essential1 Study for treatment of ET in the third quarter of 2021 and has started enrolling participants. Topline results are expected in the second half of 2022. Essential1 is a placebo-controlled, dose-ranging clinical trial designed to evaluate the safety, tolerability and efficacy ofPRAX -944 at 20, 60 or 120 mg per day. - Praxis plans to initiate a
PRAX -114 Phase 2, placebo-controlled, crossover study for daytime treatment of ET to evaluate safety, PK and efficacy of 10 or 20 mg ofPRAX -114 in the fourth quarter of 2021. Topline results are expected in the second half of 2022. - The Company intends to initiate a Phase 2 trial to evaluate the safety, PK and efficacy of
PRAX -944 as a non-dopaminergic treatment for the motor symptoms of Parkinson’s disease in the first half of 2022. - Praxis plans to host a Movement Disorder Day in
New York City and virtually onFriday, December 17, 2021 .
Rare Disease
- Praxis has completed the dosing and safety follow-up period for its single ascending dose (SAD) and multiple ascending dose (MAD) cohorts up to 150 and 120 mg, respectively, in its
PRAX -562 Phase 1, healthy volunteer study. A summary of the findings is included below and in the slide deck accompanying our third quarter 2021 corporate update in the Investors + Media section of our website.PRAX -562 was well-tolerated, with no clinically significant safety findings. The most common treatment emergent adverse events (TEAEs) were headache and dizziness. Almost all TEAEs were mild in severity. No drug-related serious adverse events or severe adverse events were observed.- The maximum observed concentration was observed between 2 and 3 hours after dosing. There was no impact of food intake on PK. The half-life of
PRAX -562 is approximately 4-5 days across the dose range evaluated. - Dose-related changes were observed in the exploratory Auditory Steady-State Response (ASSR) electroencephalogram (EEG) translational biomarker. In the 120 mg dose group, a reduction in ASSR of greater than 50% was observed after 14 days QD as compared to baseline.
- Based on the observed signal in the ASSR marker in the Phase 1, healthy volunteer study, Praxis has started dosing patients in the
U.S. in aPRAX -562 Phase 1, placebo-controlled, two-cohort EEG study to validate the observed signal. Topline data is expected in the first half of 2022. The study is intended to evaluate ASSR as a biomarker for thePRAX -562 program to further support selection of therapeutic dose levels in Phase 2 studies. - The Company intends to initiate a
PRAX -562 Phase 2 trial in the fourth quarter of 2021 in theU.S. for treatment of patients with rare adult cephalgias, including a cohort of participants with Short-lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT) and Short-lasting Unilateral Neuralgiform headache with Autonomic symptoms (SUNA), and a cohort of participants with Trigeminal Neuralgia (TN). - Praxis plans to initiate a
PRAX -562 Phase 2 trial for treatment of developmental epileptic encephalopathies (DEEs) in the first half of 2022. - Praxis has completed the Investigational New Drug (IND) enabling toxicology study for its lead antisense oligonucleotide (ASO) candidate,
PRAX -222, and plans to initiate regulatory submissions in order to begin aPRAX -222 Phase 1/2 trial for treatment of SCN2A-DEE in the first half of 2022.
