What this trial studies

This study evaluates the safety and tolerability of E7386 when used in combination with other anticancer drugs, including lenvatinib, doxorubicin, and paclitaxel, in patients with solid tumors. The primary goal is to determine the recommended Phase 2 dose of E7386, particularly focusing on its use in endometrial carcinoma. Participants will be monitored for adverse effects and overall response to the treatment regimen.

Who should consider this trial

Good fit: Ideal candidates include individuals with unresectable hepatocellular carcinoma or other solid tumors for which no effective standard therapy exists.

Not a fit: Patients with resectable tumors or those who have effective standard treatment options may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients with solid tumors who have limited therapeutic alternatives.

How similar studies have performed: Other studies have shown promise in combining targeted therapies with traditional chemotherapy for solid tumors, suggesting potential for success in this approach.

10. For HCC Subpart in Expansion Part only: prior systemic therapy for locally advanced or metastatic disease is as defined below

    a. Participants who have received only one prior line of immuno oncology (IO) based regimen and have progressed on or after prior treatment with IO based regimen, or IO ineligible participants who have received no prior systemic therapy. Participants who previously received lenvatinib treatment are ineligible
11.
