What is the mechanism of action of this treatment?

Common cancer treatments often involve enzyme inhibition, which is crucial for targeting specific pathways that cancer cells use to grow and survive. Cabozantinib, a tyrosine kinase inhibitor, blocks enzymes involved in tumor growth and angiogenesis, thereby starving the tumor of nutrients and inhibiting its growth. Pamiparib, a PARP inhibitor, prevents cancer cells from repairing DNA damage, leading to cell death. These targeted therapies are significant for cancer patients as they offer the potential for more effective treatments with fewer side effects compared to traditional chemotherapy, improving overall outcomes and quality of life.

What side effects are associated with this type of intervention?

Enzyme inhibition treatments for cancer, such as Cabozantinib and Pamiparib, commonly cause a range of side effects. These can include fatigue, nausea, diarrhea, decreased appetite, and hyperglycemia. More severe adverse events may involve increased levels of amylase and lipase, anemia, and decreased neutrophil counts. While these treatments can be effective in halting tumor growth, patients often experience significant treatment-related toxicity that requires careful management.

What prior FDA approvals exist?

Several enzyme inhibitors have received FDA approval for cancer treatment. Tyrosine kinase inhibitors like cabozantinib, which targets multiple kinases including MET, VEGFR, and RET, are approved for various cancers such as medullary thyroid cancer and renal cell carcinoma. Other similar drugs include vandetanib and lenvatinib. PARP inhibitors like pamiparib, which inhibit the enzyme poly (ADP-ribose) polymerase, are used in cancers with BRCA mutations. FDA-approved PARP inhibitors include olaparib, rucaparib, and niraparib, which are used for ovarian, breast, and prostate cancers. These drugs work by blocking enzymes essential for DNA repair, thereby preventing cancer cell growth.

What other types of research exist?

Promising alternatives to Cabozantinib and Pamiparib for cancer treatment in 2024 include Niraparib, Olaparib, Selpercatinib, Infigratinib, Pembrolizumab, and Nivolumab. These therapies have shown efficacy in clinical trials for various advanced or refractory cancers.

Summary

This trial is testing cabozantinib and pamiparib in patients with advanced or treatment-resistant solid tumors. The goal is to find the best dose and understand the side effects. These drugs work by blocking enzymes that cancer cells need to grow.

Who is the study for?

Adults with advanced solid tumors that are resistant to standard treatments or have no standard treatment options available. Participants must have specific genetic markers related to tumor growth, be able to take oral medication, and not have had certain recent treatments. They should also meet various health criteria like adequate blood cell counts and organ function, agree to use effective contraception, and not be pregnant or breastfeeding.

What is being tested?

The trial is testing the combination of two drugs, Cabozantinib and Pamiparib, for their effectiveness in stopping tumor growth by inhibiting enzymes needed for cell proliferation. It aims to determine the optimal dosages and document any side effects when used together on patients with refractory advanced solid tumors.

What are the potential side effects?

Potential side effects may include but are not limited to fatigue, digestive issues such as nausea or diarrhea, changes in blood pressure or heart rhythm disturbances (QTc prolongation), liver enzyme alterations indicating potential liver damage, possible bleeding complications if taking anticoagulants concurrently, and increased risk of infection.
