Evaluation of UCPVax Vaccine +/- Pembrolizumab Combined With Standard Treatment as Adjuvant Therapy in Patients With Unmethylated MGMT Glioblastoma

Glioblastomas (GBM) are the most frequent brain tumors and one of the most lethal adult cancers despite maximal multimodal therapy. Despite maximal safe resection followed by radiotherapy and temozolomide (TMZ) ± tumor-treating fields, median overall survival for newly diagnosed GBM remains around 18 months and long-term survival is rare, and recurrence is nearly universal. So, the development of new therapeutic strategies is a critical unmet need in GBM. Despite the limited success of anti-PD(L)-1 therapy, immunotherapy remains a promising option in GBM. Current challenge supports to develop combinatorial therapy approaches considering the particular immune tumor microenvironment in GBM. Anticancer vaccines have shown promising signs of efficacy in GBM but critical factors challenge their efficacy. CD4 T help is of major interest for cancer vaccine effectiveness and for immune checkpoint inhibitors success. We previously designed UCPVax a CD4 T helper-targeted cancer vaccine derived from telomerase (TERT), a very attractive GBM-associated antigen (Adotévi O, J Clin Oncol 2023 ; Laheurte C, Cell Report Med 2025). The induction of robust tumor reactive CD4 T cell response with UCPVax together with TMZ-mediated immune effects will promote recruitment of effectors immune cells into tumor bed creating a more suitable microenvironment for anti-PD-1 action. This is a proof-of-concept phase II trial to evaluate the efficacy of maintenance therapy evaluating UCPVax +/- pembrolizumab combined to standard treatment in newly diagnosed unmethylated MGMT glioblastoma. A translational research network will be implemented to better understand the therapeutic efficacy of this combination.

LAM561 With RT and TMZ for Adults With Glioblastoma

The proposed Phase IIB/III randomized, double-blind, placebo-controlled trial in subjects with newly diagnosed primary glioblastoma multiforme (ndGBM) aims to compare the efficacy and safety of LAM561 versus placebo, given with standard of care (SoC) therapy of radiation therapy plus temozolomide (TMZ), followed by an adjuvant treatment of 6 month period of TMZ and then LAM561 or placebo in monotherapy.

A Dose-escalation Clinical Study of Intraoperative Photodynamic Therapy of Glioblastoma

The primary objective of this clinical trial is to determine the safety and tolerability of two doses of light in intraoperative PDT added to standard of care; temozolomide-based chemotherapy in male and female patients aged 18 to 75 with newly diagnosed glioblastoma. This treatment will be carried out in addition to the maximal surgical resection. Data collected during this trial will be used to design the upcoming pivotal study . The study will utilize an independent Data and Safety Monitoring Board (iDSMB) that will review safety data to allow dose escalation.

Effectiveness of MR-guided LITT Therapy in Irresectable Glioblastoma (EMITT)

The aim of this study is to investigate the (cost-)effectiveness of LITT (Laser Interstitial Thermal Therapy) in primary irresectable glioblastoma. Glioblastoma are the most common malignant brain tumors and are, due to their devastating nature and the fact that these tumors occur at a relatively young age (median 59 years), responsible for up to 7% of total life years lost from cancer before the age of 70. The current treatment of glioblastoma consists of maximal safe surgery combined with adjuvant chemoradiation therapy (CRT). However, despite this aggressive treatment, these patients still face a poor prognosis (median overall survival 14.5 - 18.5 months). In addition to that, around 30% of the patients diagnosed with a glioblastoma are not suitable for surgery. These patients miss the benefit of a resection and face an even worse prognosis (median overall survival 5.1 months). The primary aim of this project is to investigate whether laser therapy combined with CRT improves overall survival, without compromising quality of life, in comparison with CRT alone in patients with primary irresectable glioblastoma.

AV-GBM-1 vs Control as Adjunctive Therapy Following Surgery and RT/TMZ in Newly Diagnosed GBM

This is a multi-center, double-blind, 2:1 randomized phase III trial to determine whether the addition of AV-GBM-1, a therapeutic, patient-specific dendritic cell vaccine, to standard therapy increases OS of patients with a recent diagnosis of primary GBM. The intent is to enroll approximately 726 patients for tumor collection to enroll 690 who are eligible for treatment at the time of randomization and who have granted consent for participation. Because of the lack of toxicity, there are no restrictions related to performance status or blood tests at the time of treatment. The key endpoint is OS from date of first injection after RT/TMZ; secondary endpoints are PFS from date of first injection, and OS and PFS from date of randomization prior to RT/TMZ. Date of PFS will be determined by the principal investigator at each site.
