Clinical Trial Summary

The goal of this clinical research study is to learn if utomilumab, when given with ISA101b, is able to shrink or slow the growth of tumors in patients with incurable HPV+ oropharyngeal squamous cell carcinoma.

This is an investigational study. Utomilumab and ISA101b are not FDA approved or commercially available. They are currently being used for research purposes only. The study doctor can explain how the study drugs are designed to work.

Up to 27 participants will be enrolled. All will take part at MD Anderson.

Description:

Study Drug Administration:

There are 28 days in each study cycle.

You will receive utomilumab by vein every 4 weeks for up to 12 doses beginning on Cycle 1 Day

1. The drug will be given over about 1 hour each time you receive it.

You will receive ISA101b as an injection under the skin every 4 weeks for 3 doses. You will receive 2 injections each time. One may be in your arm and one in your leg.

Length of Study:

You may continue taking utomilumab for up to 1 year as long as your doctor thinks it is in your best interest. You will no longer be able to take the study drug(s) if intolerable side effects occur or if you are unable to follow study directions. You may not be able to take the study drug(s) if the disease gets worse, which is explained below.

Your participation on the study will be over after the follow-up visits.

Study Visits:

On Day 1 of Cycles 1-12:

• You will have a physical exam.

• Blood (about 1 tablespoon) will be collected for routine tests, thyroid function tests, and liver function tests.

• If you can become pregnant, blood (about ½ teaspoon) or urine will be collected for a pregnancy test.

• During Cycles 1, 2, 3, 4, 8, and 12, blood (up to 10 tablespoons) will be drawn for biomarker testing (including genetic biomarkers).

At the end of Cycle 2 and every 8 weeks after that, you will have an MRI or CT scan to check the status of the disease.

Study Continuation:

If the disease appears to have gotten worse, you may still be eligible to continue receiving your assigned study drug(s). This is because you may be benefitting from the study drug(s) even though the tumor(s) got larger. Your doctor will discuss this with you.

If this happens, your doctor will talk to you about whether or not you want to continue. If you do continue taking part in the study, you will follow the study visits as described above.

However, there are risks of continuing to receive the study drug(s) because the disease may actually be getting worse. You are still at risk for side effects due to utomilumab and ISA101b. Continuing on this study could also delay starting other treatments. The disease may get worse to the point that you are no longer able to receive other treatments. There are also risks from the additional tests that may be performed, such as biopsies and blood draws. You and your doctor will discuss these possible risks, and you will be asked to decide if you want to continue receiving the study drug(s).

End-of-Treatment and Follow-up Visits:

At about 30 days after your last study drug dose:

• You will have a physical exam.

• Blood (about 1 tablespoon) will be collected for routine tests, thyroid function tests, and liver function tests.

• If you are able to become pregnant, blood (about ½ teaspoon) or urine will be collected for a pregnancy test.

At about 70 days after your last study drug dose:

• You will have a physical exam.

• Blood (about 1 tablespoon) will be collected for routine tests, thyroid function tests, and liver function tests.

• If you are able to become pregnant, blood (about ½ teaspoon) or urine will be collected for a pregnancy test.

You will also be called every 3 months up to 1½ years and asked about your health. Each call should last about 10-15 minutes.

If you stopped taking the study drug for reasons other than the disease getting worse, you will continue to have MRI/CT scans every 8 weeks. If the disease appears to get worse, or you start a new anticancer therapy, these scans will stop.

7. Subjects must have progression within 6 months of platin exposure during definitive or palliative therapy.

8. Subjects must have measurable disease by CT or MRI per RECIST 1.1 criteria; Radiographic Tumor Assessment performed within 28 days of study inclusion.

9. Target lesions may be located in a previously irradiated field if there is documented (radiographic) disease progression in that site.

10. Subject entering the study will need to consent for mandatory biopsy at study entrance and as an optional procedure prior to C3 for biomarker evaluation. Biopsy should be excisional, incisional or core needle. Fine needle aspiration is insufficient.

11. Prior chemotherapy, monoclonal antibody therapy, must have been completed at least 4 weeks prior to start. Radiotherapy or radiosurgery must have been completed at least 2 weeks prior to start.

12. All baseline laboratory requirements will be assessed and should be obtained within -14 days of study registration. Screening laboratory values must meet the following criteria i) White blood cells (WBCs) >/= 2000/microL ii) Neutrophils >/= 1500/microL iii) Platelets >/= 100 x 10^3/microL iv) Hemoglobin >/= 9.0 g/dL Patients must not be transfused for at least 14 days prior to study entry v) Serum creatinine of </=1.5 x upper limit of normal(ULN) or creatinine clearance(CrCl) > 50 mL/minute (using Cockcroft/Gault formula) Female CrCl= 0.85 x [(140 - age in years) x weight in kg]/(72 x serum creatinine in mg/dL) Male CrCl= 1.00 x [(140 - age in years) x weight in kg]/(72 x serum creatinine in mg/dL) vi) AST </= 2.5 x ULN vii) ALT </= 2.5 x ULN viii) Total bilirubin</= 1.5 x ULN (except subjects with Gilbert Syndrome who must have total bilirubin <3.0 mg/dl).

For a teratogenic study drug and/or when there is insufficient information to assess teratogenicity (preclinical studies have not been done), a highly effective method(s) of contraception (failure rate of less than 1% per year) is required. Highly effective birth control in this study is defined as a double barrier method. Examples include a condom (with spermicide) in combination with a diaphragm, cervical cap, or intrauterine device (IUD). The individual methods of contraception should be determined in consultation with the investigator.

14. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of investigational product.

15. Women must not be breastfeeding.

16. Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. The investigator shall review contraception methods and the time period that contraception must be followed. Men that are sexually active with WOCBP must follow instructions for birth control for a period of 90 days plus the time required for the investigational drug to undergo 5 half- lives (60 days).

Exclusion Criteria:

1. Subjects with active CNS metastases are excluded. Subjects are eligible if CNS metastases are adequately treated and subjects are neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment) for at least 4 weeks prior to enrollment.
