NCT03360734 ↗	Combination of Gatipotuzumab and Tomuzotuximab in Patients With Solid Tumors	Completed	Glycotope GmbH	Phase 1	2017-11-02	This was a single arm phase Ib study to evaluate the safety and efficacy of combined Tomuzotuximab and Gatipotuzumab therapy in patients with metastatic solid tumors expressing EGFR for whom no standard treatment is available. Patients who had relapsed following their most recent line of chemotherapy and who met all other entry criteria at Screening were enrolled to receive Tomuzotuximab and Gatipotuzumab in combination. During the extension phase, instead of Tomuzotuximab a commercially avalaible anti-EGFR antibody, i.e. Cetuximab (including any approved biosimilar), Panitumumab, or Necitumumab could be given to patients with cancers for which their use is approved.

Clinical Trial Landscape for Cetuximab

Recent Developments in Clinical Research

The last two years have witnessed renewed clinical activity focusing on cetuximab's efficacy in combination therapies and novel indications. Data from the KEYNOTE and CheckMate series, as well as trials exploring resistance mechanisms, have been pivotal.

• Combination Therapy Trials: Several Phase II/III trials evaluate cetuximab combined with immune checkpoint inhibitors, such as pembrolizumab and nivolumab. For example, a notable trial (NCT04171297) assesses cetuximab with pembrolizumab in head and neck cancers, exploring synergistic effects via immune modulation.

• Resistance Mechanisms: Trials investigating cetuximab resistance include genomic profiling to stratify responders. A study (NCT03426553) assesses biomarker-driven patient selection, aiming to improve outcomes in resistant populations.

• Expansion into New Indications: Ongoing trials target cetuximab for non-small cell lung cancer (NSCLC) and gastric cancers, with early Phase I/II studies exploring its role alongside targeted therapies and chemotherapeutics.

Key Ongoing Trials

Trial Identifier	Phase	Indication	Primary Endpoint	Status	Expected Completion
NCT04534042	III	Colorectal cancer	Overall survival	Recruiting	2024
