Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Known HIV infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months and CD4 T cell count >= 200

Age >= 70 with moderate to severe comorbidity, defined as having one or more of the specified conditions within 30 days prior to registration

Must not have

Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields

Definitive clinical or radiologic evidence of distant (beyond cervical lymph node and neck tissue) metastatic disease

Timeline

Screening 3 weeks

Treatment Varies

Follow Up at 3 months post completion of imrt

Summary

This trial is testing the safety and efficacy of peposertib as a treatment for head and neck cancer that has spread to other parts of the body.

Who is the study for?

This trial is for adults with advanced head and neck cancer who can't take cisplatin. Participants must be HIV-positive on effective treatment, able to swallow tablets, willing to use contraception, have certain types of oropharynx cancer stages, measurable disease per RECIST 1.1 criteria, specific blood cell counts within range, and no history of distant metastatic disease.

What is being tested?

The trial tests the safety and optimal dose of peposertib combined with intensity-modulated radiation therapy in patients with advanced head and neck cancer. It aims to determine if this combination is more effective than radiation alone for those unable to receive cisplatin.

What are the potential side effects?

Potential side effects include reactions related to blocking enzymes needed for cell growth (which may affect normal cells as well), typical risks associated with radiation such as skin irritation or damage at the treatment site, fatigue, nausea, and other symptoms depending on which organs are affected by the therapy.

Experimental Treatment

Group I: Treatment (peposertib, IMRT)Experimental Treatment6 Interventions

Beginning 60-90 minutes before each radiation treatment, patients receive peposertib PO QD and undergo IMRT daily Monday-Friday for 7 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo CT, MRI, or 18F-FDG PET/CT during screening and follow-up.
