What is MPS-106?
MPS-106 is one of the key components in an experimental cancer treatment called TEDOPI[1]. It is a synthetically manufactured peptide, which is a small protein-like molecule. MPS-106 is part of a group of 10 peptides that make up the TEDOPI cancer vaccine[2].
TEDOPI Cancer Vaccine
TEDOPI is an investigational cancer vaccine being developed by OSE Immunotherapeutics. It is designed to stimulate the immune system to fight cancer cells. The vaccine contains 10 different peptides, including MPS-106, each chosen for its potential to activate the body’s T cells (a type of immune cell) against cancer[1][2].
Diseases Treated
TEDOPI, which includes MPS-106, is being studied for the treatment of several types of cancer:
- Non-Small Cell Lung Cancer (NSCLC): This is the most common type of lung cancer. TEDOPI is being tested in patients with advanced NSCLC who have previously been treated with immunotherapy[1].
- Ovarian Cancer: TEDOPI is being evaluated as a maintenance treatment for patients with recurrent ovarian cancer after platinum-based chemotherapy[3].
- Pancreatic Cancer: Studies are ongoing to assess TEDOPI as a maintenance therapy for patients with advanced pancreatic ductal adenocarcinoma[4].
How It Works
TEDOPI, including MPS-106, works by activating the body’s immune system to recognize and attack cancer cells. Here’s a simplified explanation of the process:
- The vaccine is given to patients who have a specific protein on their cells called HLA-A2. This protein is important for the immune system to recognize the vaccine[1].
- The peptides in TEDOPI, including MPS-106, are designed to mimic parts of cancer cells[2].
- When injected, these peptides stimulate the patient’s T cells to recognize and attack cancer cells that have similar features[1][2].
- This targeted immune response helps the body fight the cancer more effectively.
Clinical Trials
TEDOPI, which includes MPS-106, is currently being studied in several clinical trials:
- ARTEMIA Study: This is a phase 3 trial comparing TEDOPI to docetaxel (a chemotherapy drug) in patients with advanced non-small cell lung cancer who have previously been treated with immunotherapy[1].
- TEDOVA Study: This phase 2 trial is evaluating TEDOPI as a maintenance treatment for patients with ovarian cancer, either alone or in combination with another immunotherapy drug called pembrolizumab[3].
- TEDOPAM Study: This phase 2 study is looking at TEDOPI in combination with chemotherapy for patients with advanced pancreatic cancer[4].
Administration
TEDOPI, containing MPS-106, is given as an injection under the skin (subcutaneous injection). The exact dosing schedule may vary depending on the specific clinical trial, but typically involves regular injections over a period of several months[1][2][3][4].
Potential Side Effects
As TEDOPI is still in clinical trials, all of its potential side effects are not yet fully known. However, common side effects of cancer vaccines may include:
- Injection site reactions (redness, swelling, pain)
- Flu-like symptoms (fever, chills, fatigue)
- Nausea
- Muscle or joint pain
It’s important to note that the safety profile of TEDOPI is still being evaluated in ongoing clinical trials. Patients participating in these trials are closely monitored for any adverse effects[1][3][4].
