Jewelfish Trial Summary

This trial is exploring the safety and effectiveness of a new drug for Spinal Muscular Atrophy, a rare disease that causes muscle weakness.

Who is the study for?
This trial is for adults, children, and infants with Spinal Muscular Atrophy who have been part of a previous study or treated with specific drugs. Women must not be pregnant and agree to contraception; men also need to use birth control. Participants should be well enough in the investigator's opinion, and young children may need feeding tubes or ventilation as recommended.Check my eligibility
What is being tested?
The trial tests Risdiplam's safety, tolerability, how it moves through and affects the body (PK/PD) in those with SMA previously enrolled in a related study or treated with certain other medications. It's an exploratory open-label study without comparison groups.See study design
What are the potential side effects?
Risdiplam can potentially cause side effects such as sensitivity reactions due to its ingredients, issues affecting vision based on past ophthalmological diseases history exclusion criteria, and possibly gastrointestinal disturbances since tube placement might be needed.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the sample size of participants taking part in this trial?

"Unfortunately, no more participants are being solicited for this investigation. First posted on March 3rd 2017 and last revised October 26th 2022, recruitment is now closed. However, if you’re looking to join another study related to muscular atrophy or spinal cord injury there are 205 trials still open and 6 clinical trials recruiting patients with Risdiplam as a treatment option."

Answered by AI

Are there any particular demographics that are more suitable for enrollment in this clinical trial?

"The medical study is searching for 174 patients between 6 months and 60 years of age who are afflicted with muscular atrophy. Furthermore, these individuals must satisfy the following prerequisites: Previous treatment or enrollment in Study BP29420 (Moonfish) with splicing modifier RO6885247, recuperation from illness during screening time period according to Investigator's opinion; Women of childbearing potential will need negative pregnancy test results alongside agreeing to abstain from sexual intercourse using contraception measures as well as refraining from donating eggs 28 days after final drug dose; Men that meet criteria require abstinence through contraceptive methods while also declining sperm donation offers; Lastly, participants"

Answered by AI

How many facilities are currently hosting this research trial?

"Patients are able to enroll in this clinical trial at multiple sites, including Nemours Children's Hospital (Orlando, Florida), Boston Childrens Hospital (Boston, Massachusetts), and Columbia University Medical Center; The Neurological Institute of New york (New York, New York)."

Answered by AI

Is eligibility for this medical experiment restricted to adults above a certain age?

"This clinical trial only admits participants aged between 6 months and 60 years. There are 52 trials for those younger than 18, while 150 are available to the elderly population over 65."

Answered by AI

To what extent has Risdiplam been proved to be innocuous for patients?

"Our team at Power rated the safety of Risdiplam a 2, as this is presently in Phase 2 trials and only preliminary data exists confirming its security but not efficacy."

Answered by AI

Is there still capacity for participation in this experiment?

"This medical trial is no longer accepting patients, as it was last updated on October 26th 2022. If you are looking for alternative research opportunities, 205 trials related to muscular atrophy and 6 studies concerning Risdiplam are currently recruiting participants."

Answered by AI

Could you please describe any other experiments involving Risdiplam?

"Risdiplam was initially trialled in 2016 at Klinika Neurologii I Wydzialu Lekarskiego WUM w Warszawie, and 5 studies have since been completed. At present, 6 trials are live worldwide with a concentration of sites located in Orlando Florida."

Answered by AI

Does this research project present any groundbreaking discoveries?

"Presently, there are 6 live trials involving Risdiplam that span 22 countries and 23 cities. This drug was initially tested in a Phase 2 & 3 study sponsored by Hoffmann-La Roche which included 231 patients and concluded in 2016 - since then 5 other studies have been completed."
