What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing if adding the drug temsirolimus to standard chemotherapy is more effective for treating children and young adults with a type of muscle cancer that has a moderate chance of coming back. The chemotherapy drugs aim to kill or stop the growth of cancer cells, while temsirolimus may help by blocking certain enzymes needed for cancer growth.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What safety data exists for the treatment of muscle cancer with chemotherapy and Temsirolimus?

Vinorelbine, a drug used in chemotherapy, has been studied for its safety in humans. Common side effects include myelosuppression (a decrease in bone marrow activity), nausea, vomiting, and neuropathy (nerve damage). Irinotecan, another chemotherapy drug, can cause delayed diarrhea and neutropenia (low white blood cell count), with rare but serious side effects like liver and kidney issues. These drugs have been used in various cancers, and their side effects are generally manageable with proper medical care. ^{1 2 3 4 5}

What makes the chemotherapy treatment with temsirolimus unique for muscle cancer?

This treatment is unique because it combines temsirolimus, an mTOR inhibitor that has shown activity against rhabdomyosarcoma (a type of muscle cancer), with a standard chemotherapy regimen. This combination aims to enhance the anticancer effects by integrating temsirolimus with established drugs like vincristine, actinomycin-D, and cyclophosphamide, potentially offering a new approach for intermediate-risk muscle cancer. ^{1 6 7 8 9}

What data supports the effectiveness of the drug vinorelbine in treating muscle cancer?

Vinorelbine has shown effectiveness in treating advanced breast cancer and non-small cell lung cancer, with studies indicating it can improve survival rates and has a manageable safety profile. While these results are from different types of cancer, they suggest potential benefits of vinorelbine in cancer treatment. ^{1 10 11 12 13}

What Are the Treatments Tested in This Trial?

Interventions

• Cyclophosphamide
• Dactinomycin
• Irinotecan Hydrochloride
• Radiation Therapy
• Temsirolimus
• Vincristine Sulfate
• Vinorelbine

Trial Overview The study compares standard combination chemotherapy (including vincristine sulfate, dactinomycin, cyclophosphamide) alternated with other drugs like irinotecan hydrochloride or vinorelbine against the same chemotherapy plus temsirolimus. The goal is to see if adding temsirolimus better stops RMS from growing by blocking enzymes needed for cell growth.

Patients also undergo RT as in Regimen A. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients then receive vinorelbine IV over 6-10 minutes on days 1, 8, and 15 and cyclophosphamide PO QD on days 1-28. Cycles repeats every 28 days for 24 weeks in the absence of disease progression or unacceptable toxicity.

Group III: Regimen A (VAC/VI) Experimental Treatment 7 Interventions

Patients receive vincristine sulfate IV over 1 minute on day 1 of weeks 1-13, 16, 17, 19, 20, 22-26, 28, 31-34, 37, 38, and 40, dactinomycin IV over 1-5 or 10-15 minutes on day 1 of weeks 1, 7, 13, 22, 28, 34, and 40, cyclophosphamide IV over 60 minutes on day 1 of weeks 1, 7, 13, 22, 28, 34, and 40, irinotecan hydrochloride IV over 90 minutes on days 1-5 of weeks 4, 10, 16, 19, 25, 31, and 37.

The combination of cyclophosphamide, epirubicin, and vinorelbine (CEN) was administered to 56 patients with advanced breast cancer, resulting in a 50% objective response rate, with a median overall survival time of 90 weeks.

While the treatment showed acceptable tolerability, with manageable side effects like neutropenia and nausea, it did not demonstrate improved efficacy compared to other first-line treatments for advanced breast cancer.

Vinorelbine (Navelbine) demonstrated an overall response rate of 16% in heavily pretreated patients with advanced and/or metastatic breast cancer, with responses primarily observed in lymph nodes, breast tissue, and soft tissue.

The treatment was well-tolerated, with the most significant toxicities being granulocytopenia and anemia, affecting 51% and 9% of patients respectively, while other side effects were mild and rare.

Vinorelbine (Navelbine) has shown significant antitumor activity in various cancers, including a 33% response rate in non-small cell lung cancer and a 53% response rate in advanced breast cancer, based on early phase II studies.

The drug primarily causes neutropenia as a side effect, with minimal neurotoxicity and manageable other side effects, making it a promising option for cancer treatment.

Vinorelbine, an oral and intravenous chemotherapy drug, was found to have a maximum tolerated dose of 30 mg/m² in children without bone marrow involvement, with myelosuppression (reduced blood cell production) being the main side effect.

The study revealed that children metabolize vinorelbine differently than adults, showing higher plasma clearance and lower overall drug exposure, which may influence dosing strategies for pediatric patients.

The combination of temsirolimus with standard chemotherapy (VAC/VI) in children with intermediate-risk rhabdomyosarcoma was found to be feasible and well tolerated, with only 20% of patients experiencing dose-limiting toxicities.

Out of 10 patients treated, no treatment-related deaths occurred, and the regimen is currently being evaluated for its efficacy in a phase III trial against standard chemotherapy alone.
