What side effects are associated with this type of intervention?

Common treatments for solid tumors, particularly those involving RET inhibitors like TAS0953/HM06, often include targeted therapies and chemotherapy. Known side effects of RET inhibitors can include hypertension, liver function abnormalities, diarrhea, and fatigue. Broader side effects for common solid tumor treatments may also encompass nausea, vomiting, neutropenia, anemia, and increased risk of infections. These side effects vary depending on the specific drug and patient condition.

What prior FDA approvals exist?

The FDA has approved several targeted therapies for the treatment of solid tumors with specific genetic abnormalities. For instance, selpercatinib and pralsetinib are RET inhibitors approved for treating non-small cell lung cancer (NSCLC) and thyroid cancers with RET gene fusions or mutations. These drugs work by specifically inhibiting the activity of the RET protein, which is involved in cell growth and division. Other targeted therapies for solid tumors include drugs like vemurafenib and dabrafenib, which target BRAF mutations in melanoma, and trastuzumab, which targets HER2-positive breast cancer.

What other types of research exist?

Promising alternatives to TAS0953/HM06 for solid tumors with RET gene abnormalities include selpercatinib and pralsetinib. Both have demonstrated efficacy in treating RET fusion-positive cancers and are approved for use in various solid tumors.

Summary

This trial is testing a new drug called TAS0953/HM06 for patients with advanced cancers that have specific genetic changes in the RET gene. The drug aims to block this gene to stop or slow down cancer growth. The initial part will find the safest dose, and the later part will test how well it works.

Who is the study for?

This trial is for adults with advanced solid tumors that have specific RET gene abnormalities. Participants should be in good physical condition (ECOG score of 0-1 or 2), have adequate organ function, and no major recent surgeries. They must not have certain genetic mutations like EGFR or KRAS, uncontrolled heart issues, or a history of severe heart rhythm problems.

What is being tested?

The study tests TAS0953/HM06's safety and effectiveness on patients with RET-related tumors. Phase 1 determines the safest high dose to use; Phase 2 uses this dose to further evaluate treatment effects.

What are the potential side effects?

While the side effects for TAS0953/HM06 are not detailed here, similar drugs often cause tiredness, nausea, changes in blood pressure or heartbeat, liver issues, and potential allergic reactions.

Mechanism Of Action

Side Effect Profile

Prior Approvals

Other Research

RET inhibitors, such as TAS0953/HM06, work by targeting and blocking the RET signaling pathway, which is often abnormally activated in certain solid tumors. This targeted approach is significant for patients with RET gene abnormalities as it offers a personalized treatment option that can more effectively inhibit tumor growth and survival while potentially reducing side effects compared to conventional chemotherapy. Understanding these mechanisms is essential for developing new treatments and overcoming drug resistance, ultimately improving patient outcomes.
