What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety and effectiveness of a drug called alpelisib for individuals with PIK3CA-related overgrowth spectrum (PROS). PROS is a genetic disorder causing abnormal and excessive growth in certain body areas, leading to physical symptoms and functional limitations. Researchers aim to determine if taking alpelisib daily can help manage these symptoms. Suitable candidates for this trial are those with symptomatic and progressive overgrowth due to PROS, including at least one measurable lesion affecting daily life. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Is there any evidence suggesting that alpelisib is likely to be safe for humans?

Research shows that alpelisib has been tested for safety in people with PIK3CA-related overgrowth spectrum (PROS). Previous studies found that alpelisib is generally well-tolerated, though some side effects have been observed. Common side effects include high blood sugar, nausea, and diarrhea, which standard care can usually manage.

The FDA has already approved alpelisib for treating breast cancer, indicating a known safety record in humans. While this doesn't guarantee safety for PROS, it offers some reassurance.

In summary, although alpelisib can cause side effects, it has been tested before and is generally well-tolerated, especially with proper monitoring and care.12345

Why do researchers think this study treatment might be promising for overgrowth?

Most treatments for overgrowth spectrum conditions focus on managing symptoms through surgeries and supportive care. But Alpelisib works differently, targeting a specific genetic pathway known as the PI3K pathway, which is often overactive in these disorders. Researchers are excited about Alpelisib because it directly addresses the root cause of the overgrowth by inhibiting this pathway, potentially offering more precise and effective control of the condition. This targeted approach could mean fewer complications and better outcomes for both adults and children dealing with overgrowth spectrum conditions.

What evidence suggests that alpelisib might be an effective treatment for PROS?

Research has shown that alpelisib may help treat PIK3CA-related overgrowth spectrum (PROS). In one study, 37.5% of patients experienced a noticeable decrease in the size of their overgrowths. Another study found that 27% of patients had a positive response after 24 weeks. Additionally, real-world evidence suggests that alpelisib can reduce the size of problematic growths and improve symptoms in children. Although not everyone benefits, the data indicates that alpelisib can be effective for some people with PROS. Participants in this trial will be divided into two groups: Group 1 for adults and Group 2 for children and adolescents, to evaluate the effects of alpelisib across different age ranges.678910

Are You a Good Fit for This Trial?

This trial is for pediatric and adult patients aged ≥2 years with PIK3CA-related Overgrowth Spectrum (PROS). Participants must have a documented PIK3CA gene mutation, at least one measurable lesion related to PROS, and adequate organ function. They should not have isolated macrodactyly, macrocephaly or epidermal nevus without other syndromic features.
