Study To Evaluate The Safety, Tolerability And Immunogenicity Of 4 mg Of ITI-3000 In Patients With Polyomavirus-Positive Merkel Cell Carcinoma (MCC)
A Phase I, Open Label, First In Humans (FIH), Study To Evaluate The Safety, Tolerability And Immunogenicity Of 4 mg Of ITI-3000 In Patients With Polyomavirus-Positive Merkel Cell Carcinoma (MCC)
Study Overview
Detailed Description
This is a single dose design examining 4 mg dose of the DNA vaccine ITI-3000 in participants who were diagnosed with polyomavirus-positive MCC, histologically confirmed by an expert pathologist on standard clinical staining, that may have been supplemented by specific staining for Cytokeratin 20 (CK20) and/or other markers used to distinguish MCC.
Evidence of Merkel cell polyomavirus (MCPyV) in the tumor at initial presentation (pre-therapy) can be provided by a positive anti-MCPyV oncoprotein antibody AMERK Test.
Participants in the study are those who are both diagnosed and have completed standard of care (SOC) surgical and/or radiation therapy at least 1 year prior to enrollment in the study and have no evidence of active disease (NEAD). Participants those who were previously diagnosed with MCC, and had recurrence and also exhibited no evidence of active disease (NEAD) for more than 2 years prior to enrollment in the study.
NEAD is confirmed by physical examination, a negative AMERK test (<74 STU) in participants with a prior positive AMERK test, or significantly decreased, stable AMERK titers in 2 or more consecutive draws compared to prior positive AMERK test at the time of diagnosis, in the setting of a negative computed tomography (CT) scan of the chest, abdomen and pelvis or PET-CT within 3 months of enrollment into the study.
Eight participants will be enrolled at 4 mg total DNA dose to assess safety, tolerability, and immunologic response to the ITI-3000 vaccine.

Description
Inclusion Criteria:
- Evidence of Merkel cell polyomavirus (MCPyV) in the tumor at initial presentation (pre-therapy) can be provided by a positive anti-MCPyV oncoprotein antibody AMERK Test.
- Eligible participants have to be both be diagnosed and have completed SOC surgical and/or radiation therapy at least 1 year prior to enrollment in the study and have no evidence of active disease (NEAD).
- Participants who were previously diagnosed with MCC and had recurrence and also exhibited no evidence of active disease (NEAD) for more than 2 years prior to enrollment in the study.
- Age ≥ 18 years.
- Karnofsky performance status (PS) ≥ 70 or ECOG PS 0-1.
- Participant has a predicted life expectancy ≥ 3 months.
- Participant provided signed and dated informed consent prior to initiation of any study procedures.
- Participant has adequate renal function (creatinine ≤ 1.5 times the upper limit of normal [ULN]) or a glomerular filtration rate (GFR) of ≥ 50 mL/min/1.73 m2).
- Participant has adequate hepatic function, as evidenced by a total bilirubin ≤ 1.5 times the ULN, aspartate transaminase (AST), and/or alanine transaminase (ALT) ≤ 3 times the ULN.
- Participant has adequate bone marrow function, as evidenced by hemoglobin ≥ 9.0 g/dL in the absence of transfusion within the previous 72 hours, platelet count ≥ 100×109cells/L, and absolute neutrophil count (ANC) ≥ 1.5×109 cells/L.
Participant and his/her partner agree to use adequate contraception after providing written informed consent through 2 months after the last study drug dose, as follows:
- For women: Negative pregnancy test during Screening and at Baseline and compliant with two methods of medically-approved contraceptive regimens or abstinence during and for 2 months after the treatment period or documented to be surgically sterile or postmenopausal.
- For men: Compliant with two methods of medically approved contraceptive regimens or abstinence during and for 2 months after the treatment period or documented to be surgically sterile
- Participant is willing and able to participate in the study and comply with all study requirements.
Exclusion Criteria:
- Participation in another therapeutic clinical trial.
- Participant who received systemic treatment previously (e.g., chemotherapy, PD-1/PD-L1).
- Participant is pregnant or breast-feeding.
- Negative for an anti-MCPyV oncogene antibody titer or other evidence of no MCPyV involvement at initial presentation using an acceptable and specific assay at the institution.
- Known history of AIDS/HIV, other viral diseases or oncologic disorders such as untreated HCV, chronic active HBV or organ transplantation that may have immunologic consequences or require immunosuppression. No testing required.
- Participant with CLL-associated MCC.
- On-going immunosuppressive therapy for other conditions with the exception of low-dose topical, nasal or inhaled steroids.
- Participant has a history of other malignancy treated with curative intent within the previous 3 years with the exception of adequately treated non-melanoma skin cancer or carcinoma in situ of the cervix. Participants with previous invasive cancers are eligible if the treatment was completed more than 3 years prior to initiating current study treatment, and there is no evidence of recurrent disease.
- Participant has a significant medical illness or abnormal laboratory finding that, in the Investigator's opinion, would increase the risk of participating in this study.
- Participant with otherwise unexplained >10% weight loss in the last 30 days prior to the screening.
- Participant has evidence of serious active infection (i.e., infection requiring treatment with intravenous antibiotics).
