Evaluating SYH2051 for advanced solid tumors and head and neck cancer

A Phase I Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of SYH2051 Monotherapy in Patients With Advanced Solid Tumors or in Combination With Radiotherapy in Patients With Locally Advanced Head and Neck Cancer

This study is testing a new drug called SYH2051 to see if it can help people with advanced solid tumors and head and neck cancer who have run out of other treatment options.

What this trial studies

This open-label, multicenter phase I study aims to assess the safety, tolerability, pharmacokinetics, and preliminary antitumor efficacy of SYH2051 in patients with advanced solid tumors. The study includes a dose-escalation approach and evaluates SYH2051 both as a monotherapy and in combination with intensity-modulated radiation therapy for locally advanced head and neck cancer. Eligible participants will be those who have no standard therapy options available or have not responded to existing treatments.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with advanced solid tumors or locally advanced head and neck cancer who are suitable for radiotherapy.

Not a fit: Patients with early-stage cancers or those who have not been diagnosed with advanced solid tumors may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors and head and neck cancer.

How similar studies have performed: While this approach is novel, similar studies evaluating new therapies in combination with radiotherapy have shown promise in the past.

8. Concurrent serious and/or uncontrolled medical conditions at screening (e.g., severe chronic obstructive pulmonary disease);
9. Patients with abnormal thyroid function were not allowed, except those with euthyroid function after drug control;
10. History of severe cardiovascular disease;
11. History of myopathy or raised creatine kinase (CK) \>5 times the upper limit of normal (ULN);
