Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT05557240
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This is a signelcenter, open-label, single arm, first-in-human phase I trial to investigate the safety, feasibility and immune response of the novel NeoPep Vaccine in patients with newly diagnosed GB. Primary Endpoints: Determine the safety and tolerability profile of NeoPep Vaccine1and 2 when administered with immunomodulators and Stupp standard treatment. Secondry Endpoints: 1. Descriptive analysis of induced T-cell immune responses after vaccinations with NeoPep Vaccine1and 2 drug products plus immunomodulators and Stupp standard treatment. 2. Overall survival with NeoPep Vaccine1 and 2 plus immunomodulator in newly diagnosed glioma in patients treated with standard Stupp. 3. Progression-free survival with NeoPep Vaccine1 and 2 plus immunomodulator in newly diagnosed glioma in patients treated with standard Stupp. After the standard chemoradiotherapy with TMZ has been completed, Vaccination was initiated 14 days before the first maintenanceTMZ cycle. It starts with the first NeoPep Vaccine1, followed by additional NeoPep Vaccine2 at a later time point and ends with the Last Endpoint Evaluation Visit (LEEV) of a patient.

Arms & Interventions

Arms

Experimental: NeoPep Vaccine1and 2 plus polyICLC concurrent to TMZ

Interventions

Drug: - NeoPep Vaccine1 plus Poly-ICLC

NPVAC1: NPVAC1 drug products are composed of 5 peptides from the HCMV warehouse, NPVAC1 vaccine will be applied before maintenance TMZ cycles after completion of chemoradiation therapy (CRT). Beginning on day 14 before the first maintenance TMZ cycle, patients will receive 7 vaccinations with NPVAC1 drug products during 6 weeks. 400 μg per peptide per vial are used. Poly-ICLC: Poly-ICLC(500ug)will be used as immunomodulator with all vaccinations.

Drug: - NeoPep Vaccine2 plus Poly-ICLC

NPVAC2: NPVAC2 will be ready for use 2 months after enrollment, as these peptides have to be newly synthesized for each patient following identification of the mutanome and corresponding mutated peptides in the HLA ligandome. NPVAC2 drug products are composed 20 peptides de novo synthesized for an individual patient. Patients will be repeatedly vaccinated with NPVAC2 drug products beginning on day 33 of the 6 maintenance TMZ cycle.Patients will receive 9 vaccinations within 12 weeks. 400 μg per peptide per vial are used. Poly-ICLC: Poly-ICLC(500ug)will be used as immunomodulator with all vaccinations.
