What is the purpose of this trial?

This phase III trial compares the safety and effect of adding vinorelbine to vincristine, dactinomycin, and cyclophosphamide (VAC) for the treatment of patients with high risk rhabdomyosarcoma (RMS). High risk refers to cancer that is likely to recur (come back) after treatment or spread to other parts of the body. This study will also examine if adding maintenance therapy after VAC therapy, with or without vinorelbine, will help get rid of the cancer and/or lower the chance that the cancer comes back. Vinorelbine and vincristine are in a class of medications called vinca alkaloids. They work by stopping cancer cells from growing and dividing and may kill them. Dactinomycin is a type of antibiotic that is only used in cancer chemotherapy. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Vinorelbine, vincristine, dactinomycin and cyclophosphamide are chemotherapy medications that work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may have the potential to eliminate rhabdomyosarcoma for a long time or for the rest of patient's life.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but you cannot have taken certain drugs that affect liver enzymes (CYP3A4 inhibitors and inducers) within 7 days before joining. If you're on chemotherapy for non-cancer conditions, you must stop it before starting the trial.

Is the combination chemotherapy for rhabdomyosarcoma safe for humans?

The combination chemotherapy for rhabdomyosarcoma, which includes drugs like cyclophosphamide, dactinomycin, and vinorelbine, has been studied in various trials. While patients often experience some side effects like hematological toxicity (blood-related side effects), major complications are rare, and the treatment is generally considered feasible and safe for use in humans.12345

What makes the combination chemotherapy for rhabdomyosarcoma unique?

This treatment is unique because it combines vinorelbine with low-dose cyclophosphamide, which is being explored as a maintenance regimen for high-risk patients, offering a potentially new approach compared to traditional therapies that often use higher doses or different drug combinations.23678

What data supports the effectiveness of the drug combination used in the clinical trial for rhabdomyosarcoma?

Research shows that the combination of vinorelbine and low-dose cyclophosphamide has been used successfully in treating pediatric sarcomas, and the VAC regimen (vincristine, dactinomycin, and cyclophosphamide) has shown improved survival rates in low-risk rhabdomyosarcoma patients. Additionally, the VIVA regimen, which includes vinorelbine, has demonstrated significant responses in high-risk rhabdomyosarcoma patients.12349

Are You a Good Fit for This Trial?

This trial is for patients up to 50 years old with high-risk rhabdomyosarcoma (RMS), including embryonal and alveolar types, but not adult-type pleomorphic. Eligible participants must have newly diagnosed RMS, meet specific stage and group criteria, have a certain kidney function level, normal bilirubin levels unless obstructed by tumor, and provide informed consent. Pregnant or breastfeeding women are excluded as well as those with uncontrolled infections or central nervous system involvement of RMS.

Inclusion Criteria

My kidney function is normal or near normal.
I am 50 years old or younger.
My FOXO1 fusion status will be checked by the 4th week of treatment.

What Are the Treatments Tested in This Trial?

Interventions

  • Cyclophosphamide
  • Dactinomycin
  • Vinorelbine Tartrate
Trial Overview The study tests the addition of vinorelbine to standard chemotherapy (vincristine, dactinomycin, cyclophosphamide) in treating high-risk RMS. It also examines maintenance therapy post-chemotherapy to see if it helps eliminate cancer or prevent its return. The medications used aim to stop cancer cell growth by damaging their DNA.

Published Research Related to This Trial

The pilot study involving 18 patients aged 2-23 years demonstrated that the combination of vinorelbine and low-dose cyclophosphamide is feasible and shows activity against recurrent sarcomas, with one complete remission and six partial remissions observed.
Vinorelbine at a dose of 25 mg/m2 resulted in manageable toxicity, with 37% of cycles showing Grade 3 or higher neutropenia, while the recommended maintenance doses for future trials are cyclophosphamide 25 mg/m2 daily and vinorelbine 25 mg/m2 on specific days.
Vinorelbine and low-dose cyclophosphamide in the treatment of pediatric sarcomas: pilot study for the upcoming European Rhabdomyosarcoma Protocol.Casanova, M., Ferrari, A., Bisogno, G., et al.[2018]
With modern treatments, over 70% of children and adolescents with rhabdomyosarcoma can be cured, highlighting the importance of accurate diagnosis and multidisciplinary therapy for maximizing cure rates.
Current research is focusing on new therapies, including topoisomerase-I inhibitors and molecular characterization of tumors, which may lead to more effective treatments for high-risk patients who currently have poor outcomes.
Rhabdomyosarcoma: new windows of opportunity.Breitfeld, PP., Meyer, WH.[2022]
In a clinical trial involving 271 patients with low-risk embryonal rhabdomyosarcoma, a shorter treatment regimen using lower-dose cyclophosphamide and radiotherapy achieved a 3-year failure-free survival rate of 89%, indicating effective treatment without compromising outcomes.
The study demonstrated that this modified therapy resulted in significantly fewer expected treatment failures (35 observed vs. 48.4 expected), suggesting that reducing treatment duration and dosage can maintain efficacy in this patient population.
