What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of two drugs, Selumetinib (a cancer treatment) and APG-115 (also known as Alrizomadlin, an experimental treatment), to determine their effectiveness in treating individuals with Neurofibromatosis Type 1 who have specific nerve tumors. The goal is to assess whether these drugs can shrink tumors or halt their growth. The trial seeks participants with tumors that cannot be surgically removed or have metastasized. Eligible participants should have previously undergone other cancer treatments and must not have had recent major surgeries or severe medical conditions. As a Phase 1, Phase 2 trial, it aims to understand how the treatment works in people and measure its effectiveness in an initial group, offering participants a chance to contribute to groundbreaking research.

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

The trial requires that you stop taking any other anti-cancer therapies and certain herbal supplements or medications that affect specific liver enzymes at least 14 days before starting the study. If you are on immunosuppressive medications, you must stop them 14 days prior to the study, with some exceptions for low-dose or specific types of steroids.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that Selumetinib helps treat children with neurofibromatosis type 1, particularly those with inoperable tumors. In a related study, 66% of these cases responded well to the treatment, indicating that Selumetinib is generally safe for these children. Its approval for use in this condition further supports its safety.

For APG-115, less information is available about its safety. It remains under investigation in trials, with researchers closely examining its safety profile. As the trial is in early stages (Phase 1/2), the focus is on understanding its safety and tolerability.

The combination of Selumetinib and APG-115 is being tested to determine their combined efficacy. While Selumetinib has shown positive results independently, the safety of using both treatments together is still under study. Participants in this trial will contribute to understanding the safety and tolerability of this combination. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Selumetinib and APG-115 for treating neurofibromatosis because it offers a novel approach to tackling the condition. Unlike traditional treatments like surgery or radiation, Selumetinib works by inhibiting the MEK enzyme, which plays a key role in the growth of neurofibromas. APG-115 adds another dimension by targeting the MDM2-p53 pathway, which can enhance the body's ability to fight tumor cells. This dual-action approach could provide more effective control over tumor growth and improve outcomes for patients with neurofibromatosis.

What evidence suggests that this treatment might be an effective treatment for Neurofibromatosis?

Research shows that Selumetinib may help treat neurofibromatosis type 1, particularly in children with plexiform neurofibromas that cannot be surgically removed. Studies have found that 66% of these tumors either shrank or stopped growing. Adults taking Selumetinib also reported reduced pain from their tumors. APG-115 blocks a protein that aids cancer cell survival. This trial will study the combination of Selumetinib and APG-115, as they might complement each other by targeting different aspects of tumor growth. Although data on their combined use is limited, the success of each drug individually is promising. ^{1 2 3 4 6}

Published Research Related to This Trial

Selumetinib (KOSELUGO) was approved by the FDA for treating pediatric patients aged 2 and older with inoperable plexiform neurofibromas, showing a 66% overall response rate in a trial of 50 patients, with many experiencing significant symptom relief for at least 12 months.

While selumetinib is effective, it carries risks typical of MEK inhibitors, including potential ocular, cardiac, and gastrointestinal side effects, but the overall benefit-risk assessment is considered favorable for this patient population.

FDA Approval Summary: Selumetinib for Plexiform Neurofibroma. Casey, D., Demko, S., Sinha, A., et al.[2022]

Selumetinib, a MEK inhibitor, has shown significant efficacy in treating plexiform neurofibromas in patients with neurofibromatosis type 1, with 68% of 50 symptomatic patients experiencing a partial response and a median tumor volume reduction of 27.9%.

The treatment demonstrated a favorable safety profile, with manageable adverse effects, and resulted in an 84% estimated progression-free survival at 3 years, marking it as the first FDA-approved therapy for inoperable plexiform neurofibromas.

A Review of Selumetinib in the Treatment of Neurofibromatosis Type 1-Related Plexiform Neurofibromas. Anderson, MK., Johnson, M., Thornburg, L., et al.[2022]

In a clinical trial, the MEK inhibitor selumetinib showed promising results, inducing partial responses in 70% of children with neurofibromatosis type 1 and inoperable plexiform neurofibromas.

The treatment demonstrated a high progression-free survival rate of 84% after 3 years, indicating its potential efficacy in managing this condition.

Selumetinib Shrinks Tumors in Neurofibromatosis. [2021]

A Phase I study involving 24 healthy male volunteers evaluated a new granule formulation of selumetinib, showing that its absorption is comparable to the existing capsule form, making it a potential alternative for younger patients or those who have difficulty swallowing capsules.

The study found that the granule formulation was well-tolerated with low incidence of mild adverse events, and participants rated its palatability positively, indicating they would be willing to take it again.
