What is the purpose of this trial?

This trial examines a new treatment called fb-PMT for glioblastoma, a challenging brain cancer. Researchers aim to determine if fb-PMT can help by affecting multiple cancer cell signals and effectively penetrating the brain. The trial will test various doses to identify the optimal amount. Individuals with recurrent glioblastoma, who have previously undergone standard treatments like surgery and radiation, and can manage daily injections, may be suitable candidates. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but you cannot use certain medications that affect heart rhythm or specific liver transport proteins within 14 days before starting the study drug. It's best to discuss your current medications with the trial team.

Is there any evidence suggesting that fb-PMT is likely to be safe for humans?

Research has shown that fb-PMT targets and disrupts cancer cell pathways and can effectively reach brain tumors like Glioblastoma by crossing the blood-brain barrier. Although specific safety data from previous studies is unavailable, this trial is in its early stages, focusing on determining safe dosage levels of fb-PMT. Treatments in this phase are often tested in humans for the first time, so detailed safety data might not yet be available. However, reaching this stage usually indicates earlier research suggesting the treatment could be safe enough for human testing. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for glioblastoma, which often involve surgery, radiation, and chemotherapy, fb-PMT offers a novel approach by using a daily subcutaneous injection. Researchers are particularly excited about fb-PMT because it is being tested to determine the maximum tolerated dose through escalating cohorts, potentially allowing for a more personalized and effective dosing strategy. Additionally, this method of administration could lead to fewer side effects compared to traditional treatments, making it a promising option for patients seeking less invasive alternatives.

What evidence suggests that fb-PMT might be an effective treatment for Glioblastoma?

Research has shown that fb-PMT, the treatment under study in this trial, could be a promising option for glioblastoma, an aggressive brain tumor. Studies have found that fb-PMT can significantly reduce tumor growth and kill over 90% of cancer cells in lab tests. This treatment targets multiple cancer cell processes, potentially making it effective against these difficult-to-treat tumors. Notably, fb-PMT can pass through the blood-brain barrier, a challenge for many cancer drugs. Early indications suggest it could aid in treating glioblastoma, but further research is needed to confirm its effects in people. ^{1 3 6 7 8}

Published Research Related to This Trial

Glioblastoma (GBM) patients currently have a poor prognosis, with a median survival of only 14-16 months, highlighting the need for improved treatment strategies.

Recent advancements in physical treatment methods, such as fluorescent guided surgery and tumor-treating fields therapy, have shown positive results in clinical trials and are now part of standard care, while other techniques like photodynamic therapy and focused ultrasound are in development and require further validation through randomized trials.

This study is the largest real-world analysis of health-related quality of life outcomes for patients using tumor treating fields (TTFields) therapy for glioblastoma, involving 1,106 respondents from a pool of 2,815 patients.

Results indicated that longer time using TTFields therapy was associated with improved quality of life measures, such as mobility and self-care, particularly in patients with disease progression, while older age and disease progression negatively impacted quality of life.

In a study of nine UK patients with glioblastoma, Tumour Treating Fields (TTF) showed high compliance at 89%, indicating that patients were able to integrate this treatment into their care effectively.

TTF was well-tolerated with minimal side effects, and patients reported no significant decline in quality of life until late in the disease, suggesting it can be a beneficial addition to standard therapy for glioblastoma.

In a study of 13 glioblastoma patients, using O-(2-18 F-fluoroethyl)-L-tyrosine (FET)-PET for defining radiation target volumes resulted in significantly better coverage of recurrent tumor volumes compared to traditional MRI-based methods, with a median coverage of 100% versus 85%.

The FET-PET-based planning target volume (PTV) was also significantly smaller than the MRI-based PTV (median 160 ml vs. 231 ml), suggesting that this approach could reduce side effects while maintaining therapeutic efficacy.

F-FET PET imaging is effective in distinguishing late pseudoprogression from true tumor recurrence in glioblastoma multiforme, with diagnostic accuracy indicated by areas under the receiver operating characteristic curve ranging from 0.80 to 0.88.

Different analytical methods for interpreting F-FET PET images showed similar effectiveness, but those focusing on areas of highest uptake performed slightly better, highlighting the need for standardization in imaging techniques across medical centers.

In a pilot study involving 17 patients with glioblastoma, the use of dual timepoint FET-PET imaging for planning simultaneous integrated boost (SIB) radiotherapy showed promising survival outcomes, with 1-year overall survival at 73% and progression-free survival at 53%.

While the treatment did not show excessive neurotoxicity, radiation necrosis was a common side effect, occurring in 7 patients, highlighting the need for careful monitoring in future trials.

Recent treatments for glioblastoma multiforme (GBM), such as regorafenib, paxalisib, and VAL-083, show promise in slowing disease progression, with VAL-083 being notable for its ability to cross the blood-brain barrier and target DNA directly.

Clinical trials indicate that therapies like selinexor and innovative vaccines have provided initial benefits in extending survival, while maintaining a positive safety profile, though more research is needed to confirm these findings and improve patient outcomes.

Proton-beam therapy (PBT) for recurrent glioblastoma (GBM) was found to be well tolerated, with only one patient experiencing acute grade 3 toxicity and four experiencing late grade 3 toxicity, indicating a low risk of severe side effects.

In a study of 45 patients, median progression-free survival (PFS) was 13.9 months and median overall survival (OS) was 14.2 months after PBT reirradiation, suggesting that PBT offers effective treatment outcomes comparable to traditional photon reirradiation.

ImuVert, a biologic response modifier derived from Serratia marcescens, has been granted orphan drug status by the FDA and is currently being tested in a multicenter clinical trial for recurrent malignant astrocytoma, a type of brain tumor with a poor prognosis.

In phase I and II trials, ImuVert showed manageable toxicities, including mild local reactions and some cases of hypotension, indicating that while it has potential as a treatment, careful monitoring of side effects is necessary.

Patients with glioblastoma multiforme who underwent complete tumor resection had a significantly better survival rate compared to those who only had a biopsy, with a 3.82-fold greater chance of death for biopsy patients.

Among the chemotherapy options, temozolomide was associated with the longest survival rates, outperforming both carmustine (BCNU) and the PCV regimen (procarbazine/lomustine/vincristine).

In a systematic review of 19 trials involving 755 glioblastoma multiforme patients, combining molecularly targeted therapies (MTT) with radiotherapy (RT) resulted in a higher incidence of severe adverse events (SAE) compared to standard therapy, with a pooled incidence rate of 131.2 per 1000 person-months versus 74.7 for standard therapy.

Despite the increased risk of SAEs, the combination of MTT and RT did not show significant improvements in progression-free survival (PFS) or overall survival (OS) compared to standard treatments, indicating that while MTT may lead to more side effects, it does not enhance survival outcomes.
