Study Endpoints

Primary Endpoints

Safety: Number of Subjects With Treatment-emergent Adverse Events and Serious Adverse Events
Baseline through 30 days post end of treatment (up to Day 107)

Evaluations of adverse events (AEs), serious adverse events (SAEs), Adverse event of special interest - myalgia

Efficacy: Change From Baseline in Severe Impairment Battery (SIB) in the Full Analysis Set (FAS)
Primary analysis at Week 13 (day 91) after 12 weeks of treatment (up to day 107)

The primary statistical objective for efficacy was to estimate the effect of bryostatin on the mean change in the total SIB score after 12 weeks of treatment, assessed at Week 13 (day 91). Efficacy analyses were conducted according to randomized groups. The SIB is used to assess cognition in subjects with moderate and severe AD. It is divided into nine subscales that include attention, language, orientation, memory, praxis, visuospatial ability, construction, social skills, orienting head to name. Non-verbal responses are allowed, thus decreasing the need for language output. Forty questions are included with a point score range of 0-100. Lower scores indicate greater cognitive impairment.

Frequently asked questions about Bryostatin 1

What is Bryostatin used for?

Bryostatin is an investigational small molecule being developed for the treatment of Alzheimer's Disease, specifically in patients with moderately severe to severe forms of the condition. It is currently in Phase 2 clinical development and has not been approved by the FDA.

Who makes Bryostatin?

Bryostatin is being developed by Petros Pharmaceuticals, Inc., a company traded on the stock exchange under the ticker symbol PTPI. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with Alzheimer's Disease.

What phase is Bryostatin in?

Bryostatin is currently in Phase 2 clinical development. It has completed three Phase 2 clinical trials in the United States, all of which have been completed. The drug remains investigational and has not received FDA approval for any indication.

What clinical trials is Bryostatin in?

Bryostatin has completed three Phase 2 clinical trials in the United States: NCT02431468, NCT03560245, and NCT04538066. These trials enrolled a total of 377 patients with moderately severe to severe Alzheimer's Disease, with all studies being randomized, double-blind, and placebo-controlled.

How does Bryostatin work?

Bryostatin is a small molecule that works by modulating protein kinase C (PKC) activity, which is involved in synaptic plasticity and memory formation. By activating PKC, Bryostatin aims to enhance cognitive function in patients with Alzheimer's Disease, though its exact mechanism of action is still under investigation.
