New drug cocktail aims to shrink tough head and neck tumors
NCT ID NCT06062420
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests whether combining newer immunotherapy drugs (belrestotug, nelistotug, remzistotug) with the standard drug dostarlimab can shrink tumors better than dostarlimab alone in people with advanced head and neck cancer that has come back or spread. About 316 participants whose cancer has a specific protein (PD-L1) will receive one of the combinations or the standard drug. The main goal is to see how many people's tumors shrink significantly.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dostarlimab, Belrestotug, Nelistotug, Remzistotug (immunotherapy drugs)
- What this could lead to
- If successful, this could point toward more effective first-line treatment options for people with advanced head and neck cancer, potentially shrinking tumors better than current immunotherapy alone.
- What could go wrong
- This is a mid-stage trial with only 316 participants, so results may not apply to everyone. Immunotherapy can cause serious side effects like inflammation of organs, and the new combinations might not work better than the standard drug.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Have histologically or cytologically-confirmed HNSCC that is R/M and is considered incurable by local therapies. A) Subjects must not have had prior systemic therapy administered in the R/M setting. Chemoradiation therapy which was completed more than 4 months prior to signing consent if given as part of multimodal treatment for locally advanced disease is allowed B) The eligible primary tumor locations are oropharynx, oral cavity, hypopharynx, and larynx C) Subjects may not have a primary tumor site of nasopharynx (any histology) * Has measurable (target) disease based on RECIST 1.1 as determined by the investigator. * Has an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1 * Provides a tumor tissue sample obtained at the time of or after the initial diagnosis of R/M HNSCC. A fresh tumor tissue sample obtained within 90 days of screening is highly preferred, If fresh biopsy is not possible, an archival tumor specimen is acceptable unless it was obtained prior to administration of chemoradiation for the treatment of a participant's tumor. Needle or excisional biopsies or resected tissue is required. Cytological specimens such as fine needle aspirates, bone marrow samples, or cell blocks are not acceptable. Bone specimen is not acceptable. * Has tumor Programmed death ligand 1 (PD-L1) expression * If the primary tumor site is oropharyngeal carcinoma, the participant must have Human papillomavirus (HPV) results Exclusion Criteria: * Has received prior therapy with any immune checkpoint inhibitors, including antibodies or drugs targeting Programmed death protein 1 (PD-1), PD-L1, Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), T cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine based inhibitory motif domains (TIGIT), Cluster of differentiation (CD) 96, or other immune checkpoint pathways. * Participants with previous malignancies (except non-melanoma skin cancers, and the following in situ cancers: bladder, gastric, esophageal, colon, endometrial, cervical/dysplasia, melanoma, or breast) unless a complete remission was achieved at least 2 years prior to study entry AND no additional therapy is required during the study period. * Have active tumor bleeding or a high risk of bleeding (examples include but are not limited to radiographic evidence of major blood vessel invasion/infiltration or tumor demonstrates \>90 degree abutment or encasement of a major vessel \[carotid, jugular, bronchial artery\] and/or exhibits other high-risk features such as arteriovenous fistula). * Has PD within 4 months of completion of curatively intended treatment for locoregionally advanced HNSCC * Participants with any carcinomatous meningitis or leptomeningeal spread and those with uncontrolled or symptomatic Central Nervous System (CNS) metastases * Active autoimmune disease that has required systemic disease-modifying or immunosuppressive treatment within the last 2 years. (Stable, medically managed autoimmune endocrinopathies are acceptable if participant otherwise meets entry criteria.)
