Study Summary

This trial studies the side effects and best dose of APX005M in treating younger patients with primary malignant central nervous system tumor.

Who is the study for?
This trial is for children and young adults aged 1 to 21 with primary malignant non-brainstem CNS tumors that are recurrent, progressive, or refractory, or those newly diagnosed with DIPG. Participants must have stable neurological deficits, adequate organ function, not be pregnant or breastfeeding, use effective contraception methods if applicable, and meet specific recovery criteria from previous treatments.Check my eligibility
What is being tested?
The trial tests APX005M's safety and optimal dosage in treating aggressive brain tumors in the young. It activates immune cells and may directly kill tumor cells expressing CD40. The study includes patients with new diagnoses of diffuse intrinsic pontine glioma (DIPG) as well as those with recurring or resistant CNS tumors.See study design
What are the potential side effects?
Potential side effects of APX005M include reactions related to immune activation such as inflammation in various organs; it might also cause cytotoxic effects on certain tumor cells which could lead to a range of symptoms depending on the affected area.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are there any dangers in using APX005M to treat cancer patients whose tumors have not responded to other treatments?

"While there is some data suggesting efficacy, APX005M's safety is mostly unknown due to the fact that this is only a Phase 1 trial. As such, it received a score of 1."

Answered by AI

Are there other drugs like APX005M that have been tested on people with brain cancer that keeps coming back or doesn't respond to treatment?

"MD Anderson Cancer Center conducted the first study of APX005M in 2017 as a treatment for patients with recurrent or refractory primary malignant CNS tumors. To date, 3 such trials have been completed with 8 more active studies. A large portion of these studies are based out of Atlanta, Georgia."

Answered by AI

Are people who are over 20 welcome to participate in this research project?

"According to the eligibility requirements, patients that fall between 1 year old to 21 years old can apply to be in this clinical trial. Out of the 834 similar studies, this is one of the 209 studies that focus on a pediatric population and one of the 625 studies for people over the age of 65."

Answered by AI

What are the goals that this team of researchers is hoping to achieve?

"The primary outcome of this 2-year study will be to understand the pharmacokinetics of APX005M. Additionally, researchers will also be evaluating the duration of response, overall survival for DIPG patients, and progression-free survival."

Answered by AI

Is this clinical trial novel in design or execution?

"Since 2017, APX005M treatment for recurrent or refractory primary malignant CNS tumor patients has been studied by medical researchers. The first study, which had 41 participants, was conducted in 2017 and sponsored by Apexigen, Inc. After the successful first study, APX005M received Phase 1 & 2 drug approval. Currently, there are 8 active studies being conducted in 22 cities and 3 countries."

Answered by AI

Can people with the required qualifications sign up for this research project at the present time?

"Yes, this is an active recruitment trial that was originally posted on February 2nd, 2018. The study is looking for 45 patients to enroll from 11 different sites."

Answered by AI

Who meets the standard to participate in this research?

"This study is looking for 45 patients, within the ages of 1 and 21, who have medulloblastoma. It is required that participants also meet the following criteria:-Diagnosis: Recurrent or refractory primary malignant CNS tumor patients must have a histologically confirmed diagnosis of a primary malignant non-brainstem CNS tumor (excluding DIPG patients) that is recurrent, progressive, or refractory. All tumors must have histologic verification at either the time of diagnosis or recurrence, except patients with marker (+) CNS germ cell tumors.-Available Pre-trial"
