Non-interventional Study of Patients With PN NF1 Starting Selumetinib in Russia

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the effectiveness, safety of selumetinib and patient's parameters of symptomatic inoperable PN NF1 in real clinical practice in Russia

Detailed Description
-----------------
This study will be non-interventional retrospective and prospective study. Assessment of parameters will be carried out as if a patient is treated in real-life clinical setting. The patients should be enrolled into this project after evaluation of eligibility criteria by an investigator 10 clinical sites. No additional procedures besides those already used in the routine clinical practice will be applied to the patients. Study population will consist of pediatric patients aged 3 years and older with NF1 and symptomatic inoperable PN who were prescribed with selumetinib

Conditions

Neurofibroma

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: NF1 diagnosed (according to the criteria for evaluating NF1), Symptomatic inoperable PN, Patients receiving therapy with selumetinib. For newly treated patients - registration on the first day of starting treatment with selumetinib, Age at starting of selumetinib treatment ≥ 3 to ≤ 18 years old (included in the study or started the therapy at the age of 18 years old), Patients whose parents or guardians have signed a consent form. Exclusion Criteria: Patients currently participating in an interventional study/clinical trial, Patients are excluded if there is evidence of an optic glioma, malignant glioma, malignant peripheral nerve sheath tumor, or other cancer, requiring treatment with chemotherapy or radiation therapy, Patients who receive other antitumor treatment options on optic nerve glioma, malignant glioma, malignant tumor of the peripheral nerve sheath, or other cancer. If the patient on selumetinib treatment develop optic nerve glioma, malignant glioma, malignant tumor of the peripheral nerve sheath, or other cancer, he can continue selumetinib therapy +\- other treatment options on physician decision, Female patients above 12 age who are pregnant /plan to become pregnant or at breast feeding.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| ORR in patients receiving selumetinib according to REiNS criteria | ORR (Overall response rate) in patients receiving selumetinib according to REiNS criteria: ORR is defined as the number of patients with CR (complete response) or cPR (confirmed partial response). CR is defined as disappearance of the target lesion. PR is defined as decrease in the volume of the target PN by 20% or more compared to the baseline and is considered unconfirmed at the first detection, confirmed when observed again within 3-6 months, and durable when the response is maintained for 1 year or longer In this trial ORR could be taken from the source records of the patient retrospectively. In this case CR or cPR counted from the therapy start date of a patient, which could have been before ICF signing. | from the FSI date (21 Mar 2023) till 36 months from FSI | 
| Best objective response on selumetinib treatment | a percentage of subjects who achieved a best response of CR, PR or stable disease during treatment | from the FSI date (21 Mar 2023) till 36 months from FSI | 
| Time to discontinuation of selumetinib |  | from the FSI date (21 Mar 2023) till 36 months from FSI | 
| Description of diagnostic algorithms for PN NF1 in Russia |  | from the FSI date (21 Mar 2023) till 36 months from FSI | 
| Reasons for discontinuation of selumetinib |  | from the FSI date (21 Mar 2023) till 36 months from FSI | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety: adverse events (date, type, severe grade, seriousness criteria, outcome); |  | from the FSI date (21 Mar 2023) till 36 months from FSI | 
| Clinical profile of patients with PN NF1 in Russia | features of molecular diagnostics, lesion volume and localization of PN (plexiform neurofibroma) | from the FSI date (21 Mar 2023) till 36 months from FSI | 
| Demographic profile of patients with PN NF1 in Russia | age, gender of patients | from the FSI date (21 Mar 2023) till 36 months from FSI |
