Neoadjuvant QL1706 (Iparomlimab + Tuvonralimab) with chemotherapy for HR-positive, HER2-negative breast cancer

NEOadjuvant Iparomlimab and Tuvonralimab (QL1706) Plus Chemotherapy in Patients With Hormone Receptor Positive And HER2-Negative Breast Cancer: a Prospective, Single Arm, Multicenter Clinical Trial

PHASE2 · RenJi Hospital · NCT07396324

This trial will test whether giving QL1706 (two immunotherapy antibodies) together with paclitaxel and carboplatin before surgery helps people with hormone receptor–positive, HER2‑negative breast cancer.

What this trial studies

This is a prospective, open‑label, multicenter Phase 2 study giving neoadjuvant QL1706 (Iparomlimab plus Tuvonralimab) combined with paclitaxel and carboplatin to patients with hormone receptor–positive, HER2‑negative breast cancer. Eligible adults must have histologically confirmed disease, at least one measurable lesion, ECOG 0–1, and adequate organ function, and must not have metastatic (Stage IV) disease. Treatment is administered before planned surgery to shrink tumors and investigators will monitor tumor response, surgical outcomes, and safety. The study is being conducted at RenJi Hospital, Shanghai Jiao Tong University.

Who should consider this trial

Good fit: Adults (≥18) with histologically confirmed hormone receptor–positive, HER2‑negative non‑metastatic breast cancer who have at least one evaluable lesion, ECOG 0–1, and adequate organ function are the intended participants.

Not a fit: Patients with metastatic (Stage IV) disease, HER2‑positive tumors, those who cannot tolerate chemotherapy or immunotherapy, or pregnant or lactating women are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, this approach could increase tumor shrinkage before surgery and potentially improve surgical outcomes or long‑term control for this breast cancer subtype.

How similar studies have performed: Neoadjuvant immunotherapy has shown benefit primarily in triple‑negative breast cancer, while its benefit in hormone receptor–positive, HER2‑negative disease remains relatively unproven and thus this approach is relatively novel for this subtype.
