DOC1021 Dendritic Cell Immunotherapy for Treatment of Newly Diagnosed Adult Glioblastoma (GBM)
Recruiting · Phase 2 · Diakonos Oncology Corporation · registry updated 2026-07-01
Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
The goal of this clinical trial is to learn if DOC1021 + pIFN alongside standard of care (SOC) will improve survival in adult patients newly diagnosed with glioblastoma (IDH-wt). It will also evaluate the safety of DOC1021 + pIFN. Researchers will compare DOC1021 dendritic cell immunotherapy regimen added to SOC compared to SOC treatment alone. Participants in the DOC1021 + pIFN + SOC arm will: * Take filgrastim subcutaneously x 5 doses and subsequently undergo a leukapheresis collection * Undergo ultrasound guided perinodal DOC1021 injections every 2 weeks for a total of 3 doses * Receive subcutaneous pIFN injections weekly for a total of 6 doses in parallel with the DOC1021 injections Both arms of the trial will: \- Visit the clinic regularly to assess quality of life, symptoms, medication use, imaging, bloodwork, and to receive SOC treatment with surgery, temozolomide chemotherapy and radiation
Inclusion
- Provision of signed and dated informed consent form
- Stated willingness to comply with all study procedures and availability for the duration of the study
- Age 18 years or older
- Presumed diagnosis of glioblastoma IDH-wt (as per the 2021 WHO Classification of CNS Tumors) deemed to be potentially resectable and deemed to be a good candidate for post-operative standard of care temozolomide and radiation therapy.
- Surgical objective is for gross total resection (GTR)/near-total resection (NTR) de-fined as ≥ 95% of contrast enhancing (CE) tumor removed plus ≤ 1 cm3 residual CE tumor. Patients with subtotal resection will still be eligible if at least 70% of the CE tumor is resected.
- Eligibility will be confirmed after surgery when diagnosis of glioblastoma IDH-wt confirmed prior to randomization. Randomization can occur with only IDH1 immunohistochemistry and when additional molecular testing is available, if glioblastoma IDH-wt is not confirmed, the participant will be deemed a screen failure and replaced.
Exclusion
- Infratentorial, recurrent, leptomeningeal or extracranial disease.
- Patients who are pregnant or breastfeeding.
- Known active HIV or hepatitis infection. Patients with HIV that is well-controlled and have undetectable viral titers remain eligible. Patients with history of HCV adequately treated such that RNA viral load is negative also remain eligible.
- Any severe or uncontrolled medical condition or other condition that could affect participation in this study as determined by the investigator, including but not limited to: uncontrolled or severe cardiac disease, systemic autoimmune disorders requiring immunosuppression in the past 2 years\*, autoimmune hyper/hypothyroidism, untreated viral hepatitis, autoimmune hepatitis. \*autoimmune disorders include but are not limited to rheumatoid arthritis, psoriasis and inflammatory bowel disease and immunosuppressive medications include DMARDs like methotrexate, TNF inhibitors, IL-6 receptor blockers, CD80/86 inhibitors, anti-CD20 and JAK inhibitors
- Treatment with another investigational drug or other experimental intervention within the last 30 days.
