What side effects are associated with this type of intervention?

Common cancer treatments, particularly chemotherapy, are associated with a range of side effects. Neuropathy, characterized by numbness and tingling, is prevalent, especially with agents like oxaliplatin and paclitaxel. Gastrointestinal issues such as diarrhea, nausea, vomiting, and stomatitis are also frequent, as seen with fluorouracil and capecitabine. Hematologic toxicities, including neutropenia and anemia, are common, particularly with drugs like gemcitabine and pemetrexed. Additionally, alopecia (hair loss) is a notable side effect, often observed with taxane-based therapies. These side effects can significantly impact the quality of life and may require supportive care measures.

What prior FDA approvals exist?

The FDA has approved several innovative treatments for advanced or metastatic cancers, including pembrolizumab and nivolumab, which are immune checkpoint inhibitors used for various malignancies. Additionally, lutetium Lu 177 vipivotide tetraxetan, a radioligand therapy, has been approved for prostate cancer. These therapies, which involve novel mechanisms of action, reflect the ongoing advancements in cancer treatment, similar to the investigational drug PF-07265807 being studied for metastatic solid tumors.

What other types of research exist?

Promising novel alternatives for cancer treatment in 2024 include: 1) Regorafenib, a multitargeted kinase inhibitor showing activity in osteosarcoma; 2) Temsirolimus, an mTOR inhibitor with some efficacy in endometrial cancer; 3) Everolimus combined with letrozole, showing clinical benefit in endometrial cancer; 4) Futibatinib, an FGFR2 inhibitor for cholangiocarcinoma; 5) Nivolumab, a PD-1 inhibitor showing activity in meningioma. These agents target various pathways and have shown potential in clinical trials.

Summary

This trial is testing a new drug called PF-07265807 in people with advanced or spreading solid tumors. The goal is to understand how the drug moves through the body, its safety, and how well patients can handle it.

See full description

Who is the study for?

This trial is for adults with certain advanced cancers who've tried other treatments without success. They should be relatively active (ECOG 0 or 1, sometimes 2), have a life expectancy over 3 months, and their cancer must meet specific criteria based on type and previous treatments. Major organ functions need to be adequate, and they can't have uncontrolled high blood pressure or serious health issues that could interfere with the study.Check my eligibility

What is being tested?

The study tests PF-07265807 alone and combined with Sasanlimab or Axitinib in patients with metastatic solid tumors. It aims to understand how these drugs are processed by the body, their safety levels, and how well they're tolerated when given individually or together.See study design

What are the potential side effects?

Possible side effects include reactions related to immune system activation such as inflammation of organs like lungs (pneumonitis), fatigue, digestive disturbances, skin issues, potential bleeding disorders due to drug interactions or pre-existing conditions.

Mechanism Of Action

Side Effect Profile

Prior Approvals

Other Research

Cancer treatments work through various mechanisms to target and destroy cancer cells. Chemotherapy uses cytotoxic agents to kill rapidly dividing cells, while targeted therapies, such as farnesyltransferase inhibitors, block specific molecular pathways essential for cancer cell survival and proliferation. Immunotherapies, like pembrolizumab, enhance the body's immune response against cancer cells. Investigational treatments, such as the ones being studied in the trial PF-07265807, often explore novel mechanisms, including disrupting cancer cell metabolism or signaling pathways. Understanding these mechanisms helps patients and doctors choose the most effective treatment, manage side effects, and improve overall outcomes.
