Total Duration
Researchers are evaluating whether adding DOC1021 dendritic cell immunotherapy combined with pIFN to the standard treatment for newly diagnosed adult glioblastoma IDH-wild type can improve survival. This phase 2 study compares this combination plus standard of care SOC against SOC alone, which includes surgery, temozolomide chemotherapy, and radiation. The safety of DOC1021 combined with pIFN is also being assessed. Participants in the DOC1021 pIFN SOC group will receive five doses of filgrastim injections followed by leukapheresis collection. They will then get ultrasound-guided DOC1021 injections near deep cervical lymph nodes every two weeks for three doses and weekly pIFN injections for six doses alongside. Both groups will continue to receive SOC treatment including surgery, chemotherapy, and radiation, with regular clinic visits. Throughout the study, participants will have frequent assessments including quality of life, symptom checks, medication use, imaging scans, and blood tests. Researchers will monitor overall survival over five years, adverse events, and disease progression using imaging criteria. The total participation includes treatment and long-term follow-up, ensuring thorough safety and efficacy evaluation.

| Factors | DOC1021 immunotherapy, pegylated interferon, and standard surgery, radiation, and temozolomide | Standard surgery, radiation, and temozolomide (SOC) |
|---|---|---|
| What is this treatment? | DOC1021 is a personalized immunotherapy created from a patient's own dendritic cells, which are loaded with tumor proteins and messenger RNA. It is given along with pegylated interferon and the current standard surgery, radiotherapy, and temozolomide chemotherapy. | Standard care consists of maximal safe surgical removal of the tumor, followed by radiotherapy (60 Gy in 30 fractions), and temozolomide chemotherapy during and after radiation. |
| Role in this study | Investigational arm evaluating whether adding a personalized dendritic cell vaccine and immunomodulator to standard care improves survival in newly diagnosed GBM. | Active comparator receiving current standard treatments for newly diagnosed GBM, reflecting established care. |
| What is the main purpose? | To test whether personalized dendritic cell immunotherapy with pegylated interferon improves overall survival when given in addition to SOC for newly diagnosed IDH-wildtype glioblastoma. | To provide the current best-practice treatment—maximal surgical removal, radiation, and temozolomide—which remains standard care for newly diagnosed IDH-wildtype glioblastoma. |
| How is it given? | After surgical tumor resection and during/after radiation and temozolomide therapy, patients have leukapheresis to collect immune cells, followed by 3 injections of DOC1021 near neck lymph nodes every two weeks, and weekly pegylated interferon for 6 weeks. | Patients receive maximal safe brain tumor removal, then standard cranial radiation therapy (60 Gy in 30 fractions over 6 weeks), and oral temozolomide chemotherapy during and after radiation. |
| Evidence status | Earlier phase I findings suggest DOC1021 immunotherapy in combination with SOC is feasible and can be safely delivered following surgical resection of GBM, but survival benefit and broader efficacy versus SOC alone remain unproven and are being evaluated in this randomized trial. | SOC involving maximal safe resection, radiotherapy, and temozolomide has previously been shown in controlled trials to prolong survival and is the internationally recognized standard for newly diagnosed IDH-wildtype GBM. |
| Important limitations | DOC1021 is investigational; efficacy and long-term safety are unknown, and its manufacturing and administration are complex, requiring specialized cell processing and repeated injections. Outcomes beyond early feasibility are still being studied. | Despite being the standard, SOC confers limited survival for most patients, and the tumor frequently recurs, underlining the need for improved treatments. |
