A Phase II Study of ALX148 plus Pembrolizumab Immunotherapy in People with Advanced Head and Neck Cancer


Full Title

A Phase 2 Study of ALX148 in Combination with Pembrolizumab in Patients with Advanced Head and Neck Squamous Cell Carcinoma (ASPEN-03/AT148003)


Pembrolizumab immunotherapy is a standard treatment for squamous cell cancer of the head and neck. This medication works by boosting the ability of the immune system to find and kill cancer cells. In this study, researchers are assessing the safety and effectiveness of adding the investigational drug ALX148 to pembrolizumab treatment in people with advanced head and neck cancer.

ALX148 works by blocking a protein called CD47. By blocking this protein, ALX148 may improve the immune response against cancer cells and help other treatments work effectively against head and neck cancer.

Participants in this study will receive pembrolizumab with or without ALX148. All of these treatments are given intravenously (by vein).

Who Can Join

To be eligible for this study, patients must meet several requirements, including:

  • Participants must have head and neck cancer that cannot be removed with surgery, has come back after treatment, or has spread (metastasized).

  • At least 2 weeks must pass since the completion of prior radiation therapy and 4 weeks since chemotherapy and receipt of the study treatment. Previous immunotherapy is not allowed.
  • Patients must be physically well enough that they are able to be mobile, take care of themselves, and engage in all but physically strenuous activities. For example, they must be well enough that they could carry out office work or light housework
