Trial Summary

Do I need to stop my current medications to join the trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, since the study is for healthy participants, it's likely that you should not be on any regular medications.

What safety data exists for Aficamten Administration or similar treatments?

In a study involving 430 healthy volunteers, the overall incidence of adverse events was 13.5%, with more events occurring in those taking active drugs compared to placebo. Common side effects included headaches, and there were no deaths or life-threatening events reported.12345

How does the drug flibanserin differ from other treatments for hypoactive sexual desire disorder?

Flibanserin is unique because it is specifically designed to be taken at bedtime, which is different from other treatments that may not have specific timing requirements. It also carries a warning about the risk of severe low blood pressure and fainting when used with alcohol, which is a consideration not typically associated with other treatments for this condition.678910

What is the purpose of this trial?

This trial tests aficamten, a drug, to see how it affects the heart's electrical activity. Healthy participants are used to get clear results without other health issues interfering. The study checks if aficamten changes the heart's rhythm.

Placebo Group
Group I: Part B (TQT Study): AficamtenExperimental Treatment1 Intervention
Participants will receive a single oral dose of aficamten. The dose will be determined based on review of Part A PK parameters, echocardiogram parameters, safety, and tolerability for aficamten.
Group II: Part A (Dose Finding Cohort 3): Aficamten 100 mgExperimental Treatment1 Intervention
Participants in this arm will receive a single oral dose up to 100 mg aficamten.
Group III: Part A (Dose Finding Cohort 2): Aficamten 75 mgExperimental Treatment1 Intervention
Participants in this arm will receive a single oral dose up to 75 mg aficamten.
Group IV: Part A (Dose Finding Cohort 1): Aficamten 50 mgExperimental Treatment1 Intervention
Participants in this arm will receive a single oral dose of 50 mg aficamten.
Group V: Part B (TQT Study): Moxifloxacin 400 mgActive Control1 Intervention
Participants will receive a single oral dose of 400 mg moxifloxacin
Group VI: Part B (TQT Study): Aficamten-matching PlaceboPlacebo Group1 Intervention
Participants in this arm will receive a single oral dose of aficamten-matching placebo.

Findings from Research

In a review of 231 randomized placebo-controlled clinical trials, it was found that a staggering 96.8% of adverse events (AEs) reported in patients taking active drugs were nonspecific, meaning they were not directly related to the medication.
The study revealed strong correlations between AE rates in placebo and active-drug groups, indicating that many reported AEs may not be caused by the drug itself, which raises concerns about the reliability of clinical trial data in assessing drug tolerability.
Types, frequencies, and burden of nonspecific adverse events of drugs: analysis of randomized placebo-controlled clinical trials.Mahr, A., Golmard, C., Pham, E., et al.[2022]
The study analyzed 345,662 spontaneous reports of adverse drug reactions (ADRs) submitted to the German Federal Institute for Drugs and Medical Devices, revealing a steady increase in reports since 1978, primarily due to stricter legal reporting requirements.
The most commonly reported ADRs were linked to drugs for nervous system disorders, with significant differences in reporting patterns between physicians and patients, suggesting a need for better patient education on potential ADRs.
Frequent Adverse Drug Reactions, and Medication Groups under Suspicion.Dubrall, D., Schmid, M., Alešik, E., et al.[2023]
In a review of 24 Phase I studies involving 430 healthy male volunteers over 5 years, the overall incidence of adverse events was 13.5%, with a higher rate for active drug treatments (15.3%) compared to placebo (7.4%).
Severe adverse events occurred in 20 cases (0.36%), but there were no deaths or life-threatening incidents, indicating that while adverse events are common, they are generally not severe in Phase I trials.
