Experimental combo targets Hard-to-Treat bone cancer
NCT ID NCT06438783
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tested a combination of two drugs—TQB2928 (an antibody that helps the immune system attack cancer cells) and anlotinib (a drug that cuts off tumor blood supply)—in 20 people with advanced osteosarcoma or other solid tumors that had stopped responding to standard treatments. The study aimed to see if the combination was safe and could slow cancer growth. However, the trial was terminated early, so results are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TQB2928 injection (a lab-made antibody targeting CD47) plus anlotinib hydrochloride capsule (a cancer drug that blocks blood vessel growth)
- What this could lead to
- If this combination works, it could offer a new treatment option for people with advanced osteosarcoma or other solid tumors that have stopped responding to standard therapy.
- What could go wrong
- This is a very early (Phase 1) trial with only 20 participants, so results may not apply to larger groups. The trial was terminated early, and the combination may cause side effects or fail to shrink tumors.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Pathological diagnosis of high-grade osteosarcoma(cohort I),dedifferentiated liposarcoma or polytypic liposarcoma(cohort II),unsuitable for local treatment; * The requirements for front-line treatment received by subjects are as follows: 1. Subjects with osteosarcoma have failed at least first-line chemotherapy and are not suitable for re-receiving first-line chemotherapy ,or progression within 6 months of the end of first-line therapy; 2. Subjects with dedifferentiated liposarcoma or polytype liposarcoma who have received at least first-line chemotherapy failure for recurrent/metastatic sites or relapse during postoperative adjuvant chemotherapy or within 6 months after treatment(considered first-line treatment failure). Exclusion Criteria: * History of hemolytic anemia from any cause (including Evans syndrome) within 3 months prior to first dosing; * Subjects with osteosarcoma or dedifferentiated liposarcoma/polytype liposarcoma who have previously used antiangiogenic tyrosine kinase inhibitors (TKI) or bevacizumab or its biosimilar, such as anlotinib, apatinib, lenvatinib, sorafenib, sunitinib, regorafenib, fruquintinib; * Previous antibody or fusion protein or small molecule drug targeting CD47 or Signal-regulatory protein α (SIRRP-α).
