Clinical Trial Summary

This is a prospective, open-label, single arm, non-randomized study of RiMO-301 with hypofractionated radiation and a PD-1 Inhibitor in patients with unresectable, recurrent or metastatic head-neck cancer.

Description:

Primary Objectives: - To determine the tolerability of RiMO-301 with hypofractionated X-ray radiotherapy and a PD-1 inhibitor (pembrolizumab or nivolumab) in patients with unresectable, recurrent or metastatic head-neck cancer - To determine the efficacy of RiMO-301 with hypofractionated X-ray radiotherapy and a PD-1 inhibitor (pembrolizumab or nivolumab) Secondary Objectives: - To evaluate progression-free survival for up to 12 months - To determine overall survival for up to 24 months - To assess patient quality of life The target population is patients with unresectable, recurrent or metastatic head-neck cancer which is clinically accessible to intratumoral injection.

Eligibility

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

Related Conditions & MeSH terms

• Head and Neck Neoplasms
• Head Neck Cancer

Intervention

Drug:
• 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.

Type	Measure	Description	Time frame	Safety issue
Primary	Determination of Recommended Dose	• The dose limiting toxicities of RiMO-301 with hypofractionated X-ray radiotherapy and a PD-1 inhibitor, as assessed by CTCAEv5, will not be observed in 33% or more patients	6 weeks
Primary	Evaluation of Anti-Tumor Response	• To determine the objective response rate: complete or partial response, as defined by RECIST and itRECIST	12 months
Secondary	Evaluation of Progression-Free Survival	Time from enrollment to local-regional recurrence, local-regional progression, distant progression or death from any cause, whichever occurs first	12 months
Secondary	Evaluation of Overall Survival	Time from enrollment to death from any cause	24 months
