Brief Title: Efficacy and Safety of Sirolimus in Children and Adolescents With Juvenile Nasopharyngeal Angiofibroma (JNA)

Official Title: Efficacy and Safety of Sirolimus in Children and Adolescents With Juvenile Nasopharyngeal Angiofibroma (JNA)

Study ID: NCT05549167

Interventions

Sirolimus

Study Description

Brief Summary: Juvenile nasopharyngeal angiofibroma (JNA) is a pathologically benign yet locally aggressive and destructive tumor that develops in the choana and nasopharynx. Historical treatment of JNA has included embolization, surgical resection, and radiation. mTOR signaling way demonstrated to be involved in regulation of growth and angiogenesis of JNA. Sirolimus, as mTOR inhibitor, is a potential target JNA therapy. The main purpose of the study is to evaluate the efficacy and safety of sirolimus in children and adolescents with primary or recurrent JNA. Efficacy will be estimated based on dynamics of the JNA progression. Historical control group will be used for comparison as standard therapy. Due to limited experience of sirolimus in JNA in routine practice, study should be conducted in 2 phases: pilot and extended. Decision regarding extended phase will be based on the results of pilot phase.

Detailed Description: Juvenile nasopharyngeal angiofibroma (JNA) is a pathologically benign yet locally aggressive and destructive tumor that develops in the choana and nasopharynx. Historical treatment of JNA has included embolization, surgical resection, and radiation. Inhibition of mTOR signaling proved to be an important point in inhibition of JNA growth and vascularization. Sirolimus (rapamun) is an mTOR inhibitor, still data on sirolimus efficacy and safety in JNA is limited to few clinical cases. The main purpose of the study is to evaluate the efficacy and safety of sirolimus in children and adolescents with primary or recurrent JNA. Historical control will be used for comparison as standard treatment. Due to limited experience of sirolimus in JNA in routine practice, study should be conducted in 2 phases: pilot and extended. The duration of the pilot phase is 3 months. Decision regarding conducting of extended phase will be based on the response to treatment in pilot phase. Response to treatment defined as a reduction of the JNA volume or stable volume or an increase in volume \< 20% from the initial one. In the extended period, duration of treatment for patients with primary JNA will be determined by the response to treatment. In case of the response to the therapy, treatment duration will be up to 9 months (3 courses by 3 months each). In case of JNA increase in volume more than 20% from the initial one (control time points 3 and 6 months), sirolimus therapy will be discontinued and surgical intervention to be provided (according to the investigator's decision). After completion of 9 months' treatment period, all patients with primary JNA will receive surgical treatment. The duration of follow up is 3 years In the group of patients with relapse or progression of JNA, therapy will continue up to 3 years or until loss of the response to the therapy (which the earliest). Optimal individual dosage of sirolimus will be determined under control of concentration in blood serum. Sirolimus therapeutic concentration - 5-15 ng/ml. Blood samples will be collected until therapeutic concertation will be achieved in 2 consecutive samples, but no more than 4 samples (on the 4th, 7th, 10th, 14th days of sirolimus admission).
