TQB2101 for adults with advanced blood cancers

A Phase I Clinical Trial Evaluating the Safety and Efficacy of TQB2101 in Subjects With Advanced Hematologic Malignancies

This trial will test whether TQB2101, an antibody‑drug conjugate that targets ROR1, is safe and can shrink tumors in adults with advanced hematologic malignancies who have no effective standard treatment options.

What this trial studies

This Phase 1 interventional trial gives TQB2101, an antibody‑drug conjugate that links a ROR1‑targeting monoclonal antibody to a cytotoxic payload, to adults with advanced hematologic malignancies. Eligible participants are 18–75 years old with ECOG performance status 0–1, measurable disease by the 2014 Lugano criteria, and adequate organ function after failing standard therapies. The drug is administered at study sites in China and the trial will monitor safety, tolerability, pharmacologic behavior, and early signs of anti‑tumor activity. Results will guide further development and dosing of TQB2101 in hematologic cancers.

Who should consider this trial

Good fit: Ideal candidates are adults (18–75) with pathology‑confirmed advanced hematologic malignancies that are measurable by Lugano criteria, who have failed standard treatments, have ECOG 0–1, expected survival >12 weeks, and meet the study's organ function requirements.

Not a fit: Patients whose tumors do not express ROR1, those with poor performance status, significant organ dysfunction, or life expectancy under 12 weeks are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, TQB2101 could provide a new targeted option that shrinks ROR1‑positive blood cancers and extends time without progression for patients who lack other treatments.

How similar studies have performed: Other early‑phase programs of ROR1‑targeted therapies and antibody‑drug conjugates have shown preliminary activity in small studies, but the approach remains experimental and not yet proven widely effective.
