SUMMARY

This is a Phase 1 open-label, multicenter study of the safety and tolerability, immunogenic effects, antitumor activity, and pharmacodynamics of SQZ-AAC-HPV as monotherapy and in combination with immune checkpoint inhibitors in HLA-A\*02+ patients with recurrent, locally advanced or metastatic human papillomavirus strain 16 positive (HPV16+) solid tumors. The study includes patients with anal, rectal, cervical, head and neck, penile, vulvar, or vaginal cancer.

Eligibility
Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: f
View:

• Male or female patients ≥18 years of age who are HLA-A\*02+ (performed during screening locally or centrally, or based on documented historic test results)

• Histologically confirmed incurable or metastatic solid tumors that are HPV16+ (performed during screening locally or centrally, or based on documented historic test results)

• Cancer must have progressed after at least 1 available standard therapy for incurable disease, or the patient is intolerant to or refuses standard therapy(ies) or has a tumor for which no standard therapy(ies) exist

• Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 1

• At least 1 measurable lesion according to RECIST 1.1

• Must have a lesion that can be biopsied with acceptable clinical risk and agree to have a fresh biopsy at Baseline and on Cycle 2 Day 8 (+/- 3 days)

• Patients must agree to venous access for the blood collection for manufacture of autologous blood product and be willing to have a central line inserted if venous access is an issue

• Adequate organ function and bone marrow reserve performed within 14 days of blood collection for manufacture of autologous blood product

Treatments
Experimental: Part 1 Monotherapy Dose Escalation Phase
In Part 1, SQZ-AAC-HPV as a monotherapy is administered every 3 weeks for up to a year.~There are 3 groups (Cohorts) in this Phase as follows:~* Cohort 1a: low dose SQZ-AAC-HPV~* Cohort 1b: high dose SQZ-AAC-HPV~* Cohort 1c: higher or lower dose SQZ-AAC-HPV
Experimental: Part 2 Combination Safety Phase
In Part 2, SQZ-AAC-HPV in combination with immune checkpoint inhibitors (1) ipilimumab, (2) nivolumab, or (3) nivolumab plus ipilimumab is administered every 3 weeks up to a year, but the immune checkpoint inhibitors may be administered up to 2 years. There are 3 groups (Cohorts) in this Phase as follows:~* Cohort 2a: SQZ-AAC-HPV RP2D (Recommended Phase 2 Dose) plus ipilimumab~* Cohort 2b: SQZ-AAC-HPV RP2D plus nivolumab~* Cohort 2c: SQZ-AAC-HPV RP2D plus nivolumab and ipilimumab
