What side effects are associated with this type of intervention?

Common treatments for ureteral tumors, particularly those involving FGFR3 inhibitors like LOXO-435, often include targeted therapies. The known side effects of FGFR3 inhibitors can include hyperphosphatemia, dry mouth, fatigue, and gastrointestinal issues such as diarrhea and nausea. Other potential side effects may include skin reactions, such as rash or dry skin, and elevated liver enzymes. It is important for patients to discuss these potential side effects with their healthcare provider to manage and mitigate them effectively.

What prior FDA approvals exist?

The FDA has approved several treatments for urothelial carcinoma, which includes ureteral tumors. Notably, Erdafitinib, an FGFR3 inhibitor, has been approved for patients with locally advanced or metastatic urothelial carcinoma with susceptible FGFR3 or FGFR2 genetic alterations. This approval is particularly relevant as it aligns with the mechanism of action being studied in the LOXO-435 trial. Other treatments for urothelial carcinoma include immune checkpoint inhibitors like Pembrolizumab and Atezolizumab, which have shown efficacy in advanced stages of the disease.

What other types of research exist?

Promising alternatives to LOXO-435 for ureteral tumors include: 1) Nivolumab plus Ipilimumab, which has shown efficacy in advanced renal cell carcinoma; 2) Cabozantinib, another effective treatment for advanced renal cell carcinoma; and 3) Pembrolizumab, which has been used in various solid tumors. These treatments are being explored in clinical trials and may offer new options for patients in 2024.

Summary

This trial is testing LOXO-435, a new drug, to see if it can help treat advanced cancers with a specific genetic change. It aims to block a gene that helps cancer cells grow. The study will check the drug's safety and effectiveness in these patients. LOX may be a potential effective therapeutic target to treat colorectal cancer.

Who is the study for?

This trial is for adults with advanced or metastatic solid tumors, including bladder cancer, that have a specific gene change (FGFR3). They must have tried all standard treatments or refuse them and be in good physical condition. Pregnant women and those with uncontrolled brain metastases, serious heart conditions, unresolved side effects from prior therapies, or certain eye disorders cannot join.

What is being tested?

The study tests LOXO-435's safety and effectiveness on cancers linked to the FGFR3 gene alteration. Participants will also receive Pembrolizumab. The trial involves different cohorts based on previous treatments and genetic profiles of the tumors. It can last up to 2.5 years.

What are the potential side effects?

Possible side effects include reactions related to immune system activation by Pembrolizumab such as fatigue, skin issues, inflammation of organs; LOXO-435 may cause similar effects due to its targeted action on cancer cells.

Other Research

The most common treatments for ureteral tumors include chemotherapy, immunotherapy, and targeted therapies such as FGFR3 inhibitors. Chemotherapy works by killing rapidly dividing cancer cells, while immunotherapy boosts the body's immune system to recognize and destroy cancer cells. Targeted therapies, like FGFR3 inhibitors (e.g., LOXO-435), specifically block the activity of the FGFR3 protein, which is often mutated in ureteral tumors, leading to uncontrolled cell growth. This targeted approach is crucial for patients with FGFR3 mutations as it directly interferes with the cancer's growth mechanism, potentially leading to more effective and personalized treatment outcomes.
