Overview
Brief Summary
The purpose of this pilot study is to determine the safety, tolerability, and the maximum tolerated dose intranasal administration of temozolomide (TMZ) as a single agent in Treatment on the patients with GBM.
Intranasal administration is a new method of treating brain tumours for the direct administration of drugs, inhibitors or viruses, with minimal involvement of the BBB. The investigators know the orally prescribed standard chemotherapy temozolomide (TMZ) is widely used to treat glioma tumours.
Received evidence of safety and efficacy in a full cycle of preclinical trials (on GLP Standart) and tests of calculated doses of intranasal administration of TMZ in healthy volunteers.
Intranasal administration of temozolomide is considered as GBM therapy, which provides direct access to a therapeutic dose of the drug into the brain (to the neoplastic process) with low toxicity
Detailed Description
The investigators are trying to evaluate a clinically potentially effective intranasal way of delivering TMZ to the brain, taking into account the anatomical structure of os ethmoidal. The most important factor in the effectiveness of the drug is the achievement of an adequate amount of the active agent in its unbound state with albumin on the blood of a patient and the exposure time to the tumour process. Failure to comply with this requirement (difficulties in overcoming the BBB) was identified as the main obstacle to the successful treatment of all types of brain tumours. Translation to improved clinical outcomes in a patient with GBM has not yet been realized. The investigators will use modified temozolomide (without changing the chemical formula) to exclude as much as possible Anosmia, Hyposmia and other violation of the identification of odours with participants.
Investigators
Eligibility Criteria
Inclusion Criteria

- •21 years or older
- •Histologically confirmed the diagnosis of Grade 4 astrocytic tumour, which includes glioblastoma, giant cell glioblastoma, gliosarcoma, and glioblastoma with oligodendroglial components
- •The availability of histological material for the possibility of revising histological verification
- •IDH 1 Mutation and IDH2 Mutation are not taken into account when enrolling in that study
- •MGMT promoter methylation MUST BE CONFIRMED
- •Must have a Karnofsky performance status of ≥ 70% and the ability to use intranasal administration
- •Sexually active fertile subjects (male and female) must agree to use accepted methods of contraception during the course of the study and for 3 months after the last intranasal administration of Temozolomide
- •Female subjects of childbearing potential must have a negative pregnancy test at screening.
- •Must be capable of understanding and complying with the protocol requirements
Exclusion Criteria

Outcomes
Primary Outcomes
The randomized study to determine the safety of Intranasal Administration of modified Temozolomide.
Time Frame: up to 60 days (or withdrawal of consent or another discontinuation criterion) from date of randomization
Incidence of Treatment-Emergent Adverse Events will be estimated by the number of participants with Glioblastoma or Gliosarcoma according to the NCI CTC (5.0) with adverse events (AE) in all cohorts.
Secondary Outcomes
- The maximum tolerated therapeutic dose (MTD) of modified Temozolomide for intranasal administration(up to 90 days (or withdrawal of consent or another discontinuation criterion) from date of randomization)
