What side effects are associated with this type of intervention?

Common treatments for endometrial cancer include radiation therapy (RT), chemotherapy, and targeted therapies. Radiation therapy can cause acute toxicity, including fatigue, urinary and bowel symptoms, and late toxicity such as long-term urinary and bowel issues. Chemotherapy, such as paclitaxel and carboplatin, can lead to side effects like neurotoxicity, fatigue, and increased risk of infections. Targeted therapies, similar to SGN-B7H4V, which are often antibody-drug conjugates, may cause side effects such as infusion reactions, fatigue, nausea, and potential organ-specific toxicities depending on the target. It is important to discuss these potential side effects with a healthcare provider to manage and mitigate them effectively.

What prior FDA approvals exist?

While there is no specific mention of FDA-approved antibody-drug conjugates targeting B7-H4 for endometrial cancer in the provided context, similar targeted therapies have been explored in other cancers. For instance, Sacituzumab Govitecan, an antibody-drug conjugate targeting TROP-2, has been approved for triple-negative breast cancer and is being considered for hormone receptor-positive, HER2-negative breast cancer. Additionally, Tisotumab vedotin, another antibody-drug conjugate, has been approved for recurrent or metastatic cervical cancer. These examples illustrate the potential of targeted therapies and antibody-drug conjugates in treating various cancers, which may be relevant to the ongoing study of SGN-B7H4V in solid tumors.

What other types of research exist?

Promising alternatives to SGN-B7H4V for endometrial cancer patients include: 1) Pembrolizumab, an immune checkpoint inhibitor targeting PD-1, which has shown efficacy in various solid tumors including endometrial cancer. 2) Bevacizumab, an angiogenesis inhibitor, which has been used in combination with chemotherapy for various gynecologic cancers. 3) CD70-targeted antibody-drug conjugates, such as those being studied for uterine leiomyosarcoma, which may have potential in endometrial cancer. 4) PARP inhibitors, particularly for patients with BRCA mutations or homologous recombination deficiency (HRD).

Summary

This trial tests a new drug called SGN-B7H4V for safety and side effects in patients with advanced or metastatic solid tumors. It aims to find the right dosage and see if the drug can effectively treat their cancer.

Who is the study for?

This trial is for adults with advanced solid tumors that are locally advanced, unresectable, or metastatic. Participants must be in good physical condition (ECOG 0 or 1), have measurable disease, and provide tumor tissue. Those with recent other cancers, brain metastases, previous similar treatments, significant neuropathy, or active corneal disease can't join.

What is being tested?

SGN-B7H4V is being tested for safety and effectiveness in treating various solid tumors. The study has three parts: determining the right dose (Parts A & B) and then assessing its safety and how well it works at that dose (Part C).

What are the potential side effects?

While specific side effects of SGN-B7H4V aren't listed here, they may include any unintended physical response to the drug besides its intended cancer treatment effect.

Other Research

Common treatments for endometrial cancer include chemotherapy, hormone therapy, and targeted therapy. Chemotherapy uses drugs to kill rapidly dividing cancer cells, while hormone therapy blocks hormones that fuel cancer growth. Targeted therapies, such as antibody-drug conjugates like SGN-B7H4V, are designed to specifically target cancer cells with minimal impact on normal cells. SGN-B7H4V targets the B7-H4 protein, which is often overexpressed in cancer cells, delivering a cytotoxic agent directly to the tumor. This precision reduces side effects and improves efficacy, making it a promising option for patients with advanced or metastatic endometrial cancer.
