Phase I Study of RiMO-301 With Radiation in Advanced Tumors

NCT ID: NCT03444714

Last Updated: 2025-09-15

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 32 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-04-10
• Study Completion Date: 2025-06-16

Brief Summary

This is a prospective, open-label, single arm, non-randomized study of RiMO-301 with radiation in patients with advanced tumors. A single escalation dose of RiMO-301 is intratumorally injected in a 3 + 3 study design to identify the recommended dose and dosing volumes.

Condition or Disease:

Patient with advanced tumor which is clinically accessible for intratumoral injection

Intervention/Treatment:

Drug - RiMO-301

Radiation - Radiotherapy

Phase:

Phase 1

Detailed Description

Primary Objectives:

• The primary objective is to determine the maximum tolerated dose (MTD) of RiMO-301 as determined by toxicity observed in patients treated with palliative radiation doses

Secondary Objectives:

• To determine clinical response after RiMO-301 and radiotherapy as assessed by clinical response rate using clinical evaluation, imaging and/or symptom relief
• To characterize adverse events of RiMO-301 in patients with advanced cancers
• To evaluate the pharmacokinetics (PK) of RiMO-301 with radiation

The target population is patients with clinically accessible lesions for intratumoral injection. Up to 3 dose levels (5%, 10%, and 15% of the total baseline tumor volume, respectively) will be tested in a 3 + 3 dose escalation study design. MTD will be defined as the dose associated with a dose limiting toxicity (DLT) in less than or equal to 33% of patients at the dose level tested. Dose limiting toxicity (DLT) is defined as one of the following events occurring from the intratumor injection of RiMO-301 to 30 days after the completion of radiation treatment:

• Grade 4 or greater treatment related hematologic or dermatologic toxicity
• Any Grade 3 or greater treatment related non-hematologic, non-dermatologic toxicity (excluding nausea, vomiting or diarrhea without maximal medical intervention)
