Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with histologically confirmed metastatic or unresectable soft tissue sarcoma who have received one to two prior lines of cytotoxic therapy.

Probably not a fit

Patients with resectable soft tissue sarcoma or those who have not received prior systemic therapy may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the safety, tolerability, and efficacy of a novel antibody-drug conjugate called ADCE-D01 in patients with metastatic or unresectable soft tissue sarcoma. The study will assess the incidence of dose-limiting toxicities (DLTs) to determine safety, while efficacy will be measured through various endpoints such as overall response rate (ORR), duration of response (DOR), progression-free survival (PFS), clinical benefit rate (CBR), and time to response (TTR) according to RECIST v1.1 criteria. The trial is designed in two phases, allowing for a comprehensive evaluation of the treatment's effects.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced soft tissue sarcoma who have limited treatment alternatives.

How similar studies have gone: Other studies involving antibody-drug conjugates have shown promising results in treating various cancers, suggesting potential for success with this approach.

2. Histologically confirmed STS with metastatic and/or unresectable disease (not amenable to treatment with curative intent).
3. Prior treatment with at least one but no more than two lines of cytotoxic systemic therapy for metastatic/unresectable disease.

Exclusion Criteria:

2. Primary brain malignancy or known, untreated central nervous system (CNS) or leptomeningeal metastases, or symptoms suggesting CNS involvement.
3. Clinically significant cardiovascular disease
4. Patients with acute infection with human immunodeficiency virus (HIV) 1 or HIV 2.
