Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Diagnosis of head-neck cancer that requires palliative radiotherapy
  • Patients with unresectable, recurrent or metastatic HNSCC, regardless if the patients have progressed on or are intolerant to platinum-based chemotherapy prior to study enrollment or if the patients are receiving pembrolizumab in the first line:

  • receiving a PD-1 inhibitor (pembrolizumab or nivolumab) as a standard of care, or
  • suitable to receive a PD-1 inhibitor (pembrolizumab or nivolumab) as a standard of care in the discretion of the treating physician or Principal Investigator
  • Must have at least 1 target lesion that is clinically accessible to RiMO-301 injection and amenable to receive RT regimens specified in this protocol
  • The selected target lesions must be measurable on cross-sectional imaging and repeated measurements at the same location should be achievable
  • Target tumor not in the previously irradiated field or in the field irradiated at least six months prior to RiMO-301 injection and with no complications from the prior radiation course
  • RiMO-301 injection to multiple lesions (≤ 5 in total) in a single patient is allowed as long as the total tumor volume does not exceed 250 cm3
  • Patient must have recovered from acute toxic effects (≤ grade 1 CTCAEv5) of previous cancer treatments prior to enrollment
  • Have adequate bone marrow reserve and adequate liver function
  • Have a life expectancy of at least 12 weeks
  • ECOG score of 0-2
  • Age 18 years or older

Exclusion Criteria:

  • Have signs or symptoms of end organ failure, major chronic illnesses other than cancer, or any severe concomitant conditions
  • Symptomatic central nervous system metastases and/or carcinomatous meningitis
  • Active autoimmune disease that has required systemic treatment in the past 2 years
  • Ongoing clinically significant infection at or near the incident lesion
  • Major surgery over the target area (excluding placement of vascular access) ≤21 days from beginning of the study drug or minor surgical procedures ≤7 days. No waiting is required following implantable port, enteral feeding tube and catheter placement
  • Has received any approved or investigational anti-neoplastic agent or immunotherapy other than PD-1 inhibitors (pembrolizumab or nivolumab) within 4 weeks prior to RiMO-301 injection
  • Patients with lesions which have significant blood vessel involvement (such as carotid artery encasement) or other major structures

Interventions and Outcome Measures

Arms

experimental: RiMO-301

Intratumoral injection of RiMO-301 followed by pembrolizumab or nivolumab followed by hypofractionated radiation

Interventions

RiMO-301

A single dose of RiMO-301 will be administered via an intratumoral injection.

PD-1 inhibitor (pembrolizumab or nivolumab) will be administered via a 30-minute intravenous infusion until disease progression or unacceptable toxicity.

Patients will receive hypofractionated radiation in 5 fractions.

Primary outcome measure

  • Determination of Recommended Dose [ Time Frame: 6 weeks ]
  • Evaluation of Anti-Tumor Response [ Time Frame: 12 months ]
