Brief Summary

Open-label study using ASP-1929 photoimmunotherapy in combination with anti-PD1 therapy in patients with recurrent or metastatic head and neck and squamous cell cancer or advanced or metastatic cutaneous squamous cell carcinoma.

Detailed Description

This basket trial study has 3 sub-studies:

Sub-study 1 (181 HNSCC) will enroll patients with recurrent or metastatic (R/M) squamous cell cancer of the head and neck (HNSCC). HNSCC patients are required to have positive expression of programmed cell death ligand 1 (PD-L1) defined by Combined Positive Score (CPS) ≥1.

Sub-study 2 (181 cuSCC) will enroll patients with locally advanced or metastatic cutaneous squamous cell carcinoma (cuSCC).

Sub-study 3 (181 2LcuSCC) will enroll patients with locally advanced or metastatic cutaneous squamous cell carcinoma who have progressed on anti-PD-1 therapy.

Eligible patients will enroll in the applicable sub-study and receive ASP-1929 photoimmunotherapy (PIT) treatment in combination with an anti-PD-1 therapy for up to 24 months. During the treatment period, patients will undergo clinical assessments and be monitored for safety and tolerability and disease progression by modified RECIST 1.1 for overall response rate (ORR), progression-free survival (PFS), and duration of response (DOR).

Each sub-study is an open-label, single-arm study. For each sub-study, the primary objectives are to characterize the safety and tolerability of ASP-1929 PIT treatment in combination with anti-PD-1 treatment and to assess the effect of ASP-1929 PIT treatment with anti-PD1 therapy on tumor response.

Eligibility Criteria

Inclusion Criteria

Provide written informed consent

• Cancers as follows:

Sub-study 1: Histologically or cytologically confirmed recurrent locally and/or metastatic head and neck squamous cell carcinoma with Combined Positive Score (CPS) ≥ 1 as determined by a CLIA certified and/or FDA approved test.

Note: A multi-disciplinary group (including a surgeon and radiation oncologist) must agree that the patient is not a candidate for locoregional therapy.

Sub-study 2: Histologically or cytologically confirmed locally advanced or metastatic cutaneous squamous cell carcinoma not amenable to definitive surgery or radiation.

Sub-study 3: Histologically or cytologically confirmed locally advanced or metastatic cutaneous squamous cell carcinoma not amendable to definitive surgery or radiation.

• At least one site of disease accessible to light illumination.
• Measurable disease by modified RECIST 1.1.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• No prior systemic therapy administered in the recurrent and/or metastatic setting (with the exception of systemic therapy completed ≥ 6 months prior if given as part of multimodal treatment for locally advanced disease). (Sub-study 1 only).
• Patients must be actively receiving single-agent, systemic anti-PD1 therapy at the time of screening (Sub-study 3 only).
• Disease progression despite at least 2 months of anti-PD1 therapy at the time of screening. Progression must be confirmed by at least two scans at least one month apart. Screening scan may serve as confirmation of progression (Sub-study 3 only).
• Adequate organ function.
• Female patients of childbearing potential must have a negative pregnancy test at screening and must be willing to use 2 methods of highly effective birth control while on study or be surgically sterile, or abstain from heterosexual sexual activity for the course of the study through 120 days after the last dose of anti-PD1 treatment.
• Male participants must agree to use a highly effective method of contraception starting with the first dose of study medication through 120 days after the last dose of anti-PD1 treatment.

Exclusion Criteria

• Prior therapy with an anti-PD1 or anti-PD-L1 (Sub-study 1 only).
• Prior systemic therapy that is not intended as part of definitive treatment (eg, induction, concurrent, adjuvant, or neoadjuvant treatment) (Sub-studies 1 and 2 only).
• Systemic anti-PD-1 therapy prior to current course of definitive therapy (Sub-study 3 only).
• Prior systemic therapy given as definitive treatment (chemotherapy, EGFR inhibition). Patients with a history of prior chemoradiation are eligible (Sub-study 3 only).

• Patients expecting to breastfeed during the study and through 120 days after the last dose of study treatment.
• Major surgery or significant traumatic injury ≤ 28 days before study day 1, or anticipation of the need for major surgery during the course of study treatment.
• Currently participating or participated in a study of an investigational agent and received study therapy (including RM-1929 or ASP-1929 PIT studies), or used an investigational device within 4 weeks of study Day 1.
• 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.
