Summary

This trial tests whether adding ondansetron to pyridostigmine can help patients with myasthenia gravis who suffer from stomach problems caused by pyridostigmine. Pyridostigmine helps muscles work better, but it can cause nausea. Ondansetron is used to prevent this nausea. The goal is to see if patients can tolerate higher doses of pyridostigmine without feeling sick. Ondansetron is widely used to prevent nausea and vomiting in various conditions, including chemotherapy, pregnancy, and postoperative recovery.

Who is the study for?
This trial is for individuals with anti-AchR antibody positive myasthenia gravis who are taking pyridostigmine and have had related GI side effects recently. Participants must be clinically stable, able to maintain a symptom diary, swallow liquids, and not have certain heart conditions or electrolyte imbalances. Pregnant women or those not using birth control, along with patients on specific medications like SSRIs or narcotics, cannot join.
What is being tested?
The study tests DAS-001 in a phase II trial where participants receive either the test drug or a placebo without knowing which one they get. The goal is to see if DAS-001 can help manage gastrointestinal symptoms caused by pyridostigmine in people with myasthenia gravis.
What are the potential side effects?
Potential side effects may include issues similar to what's seen with pyridostigmine use such as digestive discomfort but could also involve reactions related to ondansetron-like drugs used for nausea (e.g., headaches, constipation). Specific side effect details will depend on the actual components of DAS-001.
