Muhammadvaseem Shaikh – 2022/2023 DUNN with Cancer Brain Tumour Research Fellowship

Muhammadvaseem Shaikh

Postdoctoral Research Fellow at McMaster University, Hamilton, ON

Project Entitled: “Allogeneic, “off-the shelf” CD133 CAR-T immunotherapy for Glioblastoma”

Project Summary:

Glioblastoma (GBM) is the most common malignant brain tumor. Despite an aggressive therapy regimen, almost all patients relapse 7-9 months post-diagnosis. Therapy failure and poor patient outcome may be attributed to a small population of cells known as glioblastoma stem cells (GSCs), that escape therapy and seed disease recurrence. GSCs are most notably identified by the cell surface protein CD133, which has previously been shown to associate with pro-tumor properties including treatment resistance, tumor growth, maintenance, progression and metastasis.

Previously in the Singh Lab, we developed an engineered T-cell therapy, known as a CAR-T, that is capable of recognizing CD133 to induce tumour cell death. While this showed success in our animal models of human GBM, other considerations must be addressed on its path to clinical development. As of current, CAR-T therapies are generated from T-cells taken from cancer patients. This hosts a myriad of concerns including the quality of patient T-cells, the time and cost to manufacture, and its availability for patients with rapidly progressing disease. Hence, to circumvent this issue, we aim to develop and test the donor-derived CAR-T cells which are genetically engineered for safe usage in GBM patients as a readily available, “off-the-shelf” therapy.

Impact of Receiving Award:

I am deeply grateful and extremely honored to have received DUNN with Cancer Brain Tumour Research Fellowship Award, 2022-2024. This award will help fund my research at Dr. Sheila Singh’s lab in discovering newer therapies targeting glioblastoma.

Glioblastoma (GBM) is the most common malignant brain tumour. Despite an aggressive treatment regimen, almost all patients relapse at 7-9 months with a median survival of 14.6 months and a five-year survival of less than 5 percent. There is definitely a need to develop better therapies for GBM. Working at Singh lab provided me the exposure by working with GBM patients directly, and seeing their pain and bravery first-hand truly inspires and motivates me to work harder.

This award will help me to pursue my work of developing immunotherapies for GBM patients that would be available off-the-shelf, thereby reducing the time until treatment and also provide more potent treatment options. It would also help me to pursue my dream to work with world renowned scientists, cancer biologists and neurosurgeons. This award goes a long way in helping me grow in my career path and become a successful scientist. Finally, I would like to thank DUNN Family and Friends and Brain Tumour Foundation of Canada for helping me pursue my dream to make brain tumours treatable.
