Study of RM-1929 and Photoimmunotherapy in Patients With Recurrent Head and Neck Cancer
a study on Head and Neck Cancer
This is a two-part clinical study of patients with recurrent Head and Neck Cancer (HNC), who in the opinion of their physician, cannot be satisfactorily treated with surgery, radiation or platinum chemotherapy. The purpose of the study is to determine the safety and anti-cancer activity of various doses and repeated cycles of the experimental treatment using the study drug RM-1929 and fixed amounts of red light applied at the tumor site to activate the pharmacodynamics of the drug. The part 1 of the study has been completed and consisted in a single cycle, 3+3 dose escalation safety study of the experimental drug RM-1929 using a fixed amount of 690 nm red light. The part 1 was designed to determine the safety of the treatment as set by the maximal feasible dose or the maximal tolerable dose of RM-1929. From the part 1 results, the maximal feasible dose of RM-1929 was determined. The part 2 of the study is currently ongoing and it is evaluating the safety and anticancer efficacy of up to four repeated treatments of Photoimmunotherapy with RM-1929 at the maximal feasible dose of RM-1929 activated with a fixed amount of red light.
A Phase 1/2a Multicenter, Open-Label, Dose-Escalation, Combination Study of RM-1929 and Photoimmunotherapy in Patients With Recurrent Head and Neck Cancer, Who in the Opinion of Their Physician, Cannot Be Satisfactorily Treated With Surgery, Radiation or Platinum Chemotherapy
Photoimmunotherapy (PIT) is a new cancer targeted technology invented at the National Cancer Institute, USA. This clinical study evaluates the treatment of the experimental drug RM-1929 with Photoimmunotherapy (PIT).
The experimental drug, RM-1929, is a parental formulation consisting of a chemical conjugate of the dye IR700 with the FDA approved antibody, Erbitux® (Cetuximab), that targets EGFR receptors (EGFR is a cancer expressed protein, a cancer antigen). EGFR is highly expressed in squamous cell carcinomas of the head and neck (HNSCC). It is expected that systemic administration of RM-1929 will lead to tumor accumulation and binding to EGFR expressed at cancer cells. It is expected that treatment with RM-1929 and Photoimmunotherapy can lead to the selective destruction of the HNSCC cancer cells and provide an effective therapy to manage the disease.
The treatment using RM-1929 with Photoimmunotherapy requires two steps:
(i) the administration by infusion of the drug RM-1929 targeting the cancer protein EGFR
(ii) the illumination of the tumor with red light (690 nm) using sufficient energy to activate the drug and induce cancer cell killing.
Light illumination is applied at 24 h post drug infusion to enable sufficient time for the drug to distribute in the tumor after administration. Cell killing occurs only at cancer cells expressing the protein EGFR that is bound to the drug RM-1929. The requirement of binding of the drug to EGFR of cancer cells enables the selective destruction of cancer cells with minimum damage of healthy tissue surrounding the tumor cells. Preclinical pharmacology demonstrated that light-induced activation of RM-1929 elicits rapid tumor destruction of human cancer xenografts implanted in mice and that the treatment is cancer specific.
The Part 1 study has been completed and consisted of a single cycle 3+3 dose escalation study of RM-1929 to determine the safety of the treatment and the maximal feasible dose of RM-1929. From the part 1 of this study, the maximal feasible dose for treatment with RM-1929 was selected. The currently ongoing Part 2 of the clinical study is evaluating the safety and anti-cancer activity of up to 4 repeat treatment cycles of Photoimmunotherapy with RM-1929.

Open to people ages 18 years and up
Patients must meet the following criteria to be eligible for study participation:
- Patients with recurrent squamous carcinoma of the Head and Neck, who in the opinion of their treating physician, cannot be satisfactorily treated with surgery, radiation, or platinum chemotherapy. Diagnosis must be confirmed by biopsy and histopathology.
- Patient must have received prior systemic platinum-based chemotherapy for treatment of their head and neck cancer, unless in the opinion of the medical oncologist, the use of platinum-based chemotherapy is contraindicated or not recommended, e.g., renal impairment, allergy to platinum compounds, age, liver disease, myelosuppression,neuropathy, hearing loss, etc.
- Patients must have life expectancy > 6 months based on investigator judgment.
- Male or female patients at least 18 years old. Female patients must not be pregnant or breast feeding and must be practicing a medically acceptable form of birth control, be sterile, or post-menopausal. Females of childbearing potential (FCBP) is defined as premenopausal women capable of becoming pregnant. This includes women who are post-menopausal for at least 12 months after the last menses. FCBP must agree to use a medically acceptable form of birth control during the study and for at least 6 months after discontinuation of Erbitux® or study medication. Females must agree not to breast feed during the study and for at least two months after discontinuation of Erbitux® or study medication. Male patients should be using a double barrier protection method that is a medically acceptable form of birth control during the study or be sterile.
- Patients must have an ECOG score of 0 - 2.
- Patient must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure.

Patients with any of the following will be excluded from participation in the study:
- Patients with a history of significant Erbitux infusion reactions (≥ Grade 3).
- Patients on chemotherapy or Erbitux® therapy or radiation therapy within 4 weeks of enrollment.
- Tumor invading a major blood vessel (such as the carotid artery) unless the vessel has been embolized, stented or surgically ligated to prevent hemorrhage.
- Tumor is not clearly shown on a CT scan or clinically measurable.
- Location and extension of the tumor precludes an effective PIT.
- Patients with impaired hepatic function (ALP (hepatic), AST and/or ALT >3 times the upper normal limits, or total serum bilirubin > 2 mg/dL.
- Patients with impairment of renal function (serum creatinine >2 mg/dL).
- Unwilling or unable to follow protocol requirements.
- Any condition which in the Investigator's opinion deems the patient an unsuitable candidate to receive study drug.
- . Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- . Patient requires examinations or treatments within 4 weeks after study drug administration where they would be exposed to significant light, e.g., eye examinations, surgical procedures, endoscopy, etc.
