What this trial studies

This trial aims to assess the safety and effectiveness of TEV-56278, both as a standalone treatment and in combination with Pembrolizumab, for patients with advanced or metastatic solid tumors. It will involve dose escalation to determine the optimal dosage and evaluate the anti-tumor activity of the treatments. Participants will receive treatment for up to 12 months, followed by a follow-up period of up to 12 months, making the total duration of the trial for each participant up to 25 months.

Who should consider this trial

Good fit: Ideal candidates are patients with advanced solid tumors who have progressed on standard therapies or are intolerant to them.

Not a fit: Patients who have not received prior systemic treatment for cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this trial could provide a new treatment option for patients with advanced solid tumors who have not responded to standard therapies.

How similar studies have performed: Other studies have shown promise in using combination therapies for advanced solid tumors, suggesting potential success for this approach.
