Trial Summary

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, certain treatments like high-dose corticosteroids or recent investigational agents may affect eligibility, so it's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the treatment MK-3475 for brain cancer?

Immunotherapy, which includes treatments like MK-3475, has shown promise in treating brain tumors by helping the immune system attack cancer cells. Although specific data on MK-3475 for brain cancer is not provided, similar immunotherapy approaches have shown encouraging results in clinical trials for brain tumors, suggesting potential effectiveness.12345

Is MK-3475 safe for humans?

The research articles provided do not contain specific safety data for MK-3475, but they do mention other compounds with similar naming conventions, such as MK-462 and MK-571, which were generally well tolerated in human studies. However, this information may not directly apply to MK-3475.678910

How does the drug MK-3475 differ from other treatments for brain cancer?

MK-3475, also known as pembrolizumab, is an immunotherapy drug that works by blocking a protein called PD-1 on immune cells, which helps the immune system attack cancer cells more effectively. This mechanism is different from traditional treatments like chemotherapy, which directly kill cancer cells, and it offers a novel approach by enhancing the body's own immune response against brain cancer.12111213

What is the purpose of this trial?

This research study is studying an immunotherapy as a possible treatment for Glioblastoma.

Eligibility Criteria

This trial is for adults with Grade IV malignant glioma (glioblastoma or gliosarcoma) who have undergone initial treatment and are at their first or second relapse. Participants must be over 18, able to consent, have a performance status indicating they can carry out daily activities, and show tumor progression on scans. They should also have normal organ function as defined by the study's criteria.

Inclusion Criteria

Participants must have shown unequivocal evidence for tumor progression by MRI or CT scan.
My brain tumor is confirmed as a high-grade glioma (glioblastoma or gliosarcoma).
My cancer has returned once or twice after treatment.

Findings from Research

Malignant brain tumors remain difficult to treat, with long-term survival only improving from 6 to 15 months over the last 80 years, despite advancements in surgery, chemotherapy, and radiotherapy.
Immunotherapy, particularly using immune modulators like CTLA-4 and PD-1/PD-L1, is being actively researched in ongoing phase I and III trials, showing promise in targeting glioma antigens, but challenges remain in achieving complete responses and understanding the lack of adverse brain inflammation in these patients.
The value of EGFRvIII as the target for glioma vaccines.Lowenstein, PR., Castro, MG.[2021]
Intravenous doses of MK-462 ranging from 5 to 90 micrograms per kg were found to be well tolerated in healthy males, with linear pharmacokinetics observed for doses up to 60 micrograms per kg.
Food intake prior to oral administration of MK-462 increased its overall exposure (AUC) by about 20% but did not significantly affect peak concentration (Cmax) or half-life (t1/2), indicating that MK-462 can be taken with or without food without major impacts on its efficacy.
Pharmacokinetics and food interaction of MK-462 in healthy males.Cheng, H., Polvino, WJ., Sciberras, D., et al.[2012]
MK-8389 was found to be generally safe and well tolerated in healthy young women over a 14-day period, although it caused transient changes in thyroid function tests that limited dose escalation above 40 mg.
While MK-8389 showed acceptable systemic exposure, it did not have a clinically meaningful effect on follicular development, although higher doses did increase inhibin B levels, indicating some early follicular activity.
Oral follicle-stimulating hormone agonist tested in healthy young women of reproductive age failed to demonstrate effect on follicular development but affected thyroid function.Gerrits, MG., Kramer, H., el Galta, R., et al.[2016]
