Study Summary

This trial is assessing the safety and tolerability of Metformin in people with C9orf72 amyotrophic lateral sclerosis. The goal is to see if Metformin is safe and reduces the amount of RAN proteins produced by the C9orf72 mutation.

Who is the study for?
This trial is for individuals with C9orf72 positive ALS/FTD who can take oral food and medication, have no severe allergies to Metformin or barium sulfate, and no implanted electrical devices or metal in their body. Pregnant women, those trying to conceive, breastfeeding mothers, people with recent cancer (except skin), liver disease, renal impairment (eGFR below 30 mL/min/1.73 m2), or on hepatotoxic drugs are excluded.Check my eligibility
What is being tested?
The trial tests the safety and potential therapeutic effects of Metformin over a period of 24 weeks in patients with C9orf72 amyotrophic lateral sclerosis. It aims to see if Metformin can safely reduce harmful proteins produced by a specific genetic mutation in these patients.See study design
What are the potential side effects?
Potential side effects of Metformin may include digestive issues like nausea and diarrhea, low blood sugar levels especially when combined with other diabetes medications, vitamin B12 deficiency over long-term use which could cause anemia or nerve problems.

Frequently Asked Questions

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

Does this study admit participants younger than fifty-five years of age?

"This study is seeking out individuals aged 18 and over, up to 80 years of age."

Answered by AI

What pharmacological treatment is usually prescribed for C9orf72 positive ALS?

"C9orf72 positive ALS is regularly prescribed to treat exercise-induced afflictions. Additionally, this medication has been known to be beneficial in alleviating the symptoms of type 1 diabetes mellitus, diabetic ketoacidosis, and polycystic ovary syndrome."

Answered by AI

What other investigations have focused on C9orf72 positive amyotrophic lateral sclerosis?

"Presently, there are 170 clinical trials examining C9orf72 positive ALS. Out of those active studies, 43 have entered Phase 3. Pittsburgh is the primary base for this research, however 1903 other sites host similar experiments."

Answered by AI

What is the magnitude of enrollment in this medical experiment?

"Affirmative. According to the data listed on clinicaltrials.gov, this medical investigation is currently admitting participants; it was first posted in January 10th 2020 and updated lastly on September 15th 2022. This trial has room for 58 individuals from a single site."

Answered by AI

What safety concerns should be taken into consideration for individuals with C9orf72 positive ALS?
