Brief Title: CAR-macrophages for the Treatment of HER2 Overexpressing Solid Tumors

PRIMARY OUTCOMES

Primary Outcome 1 - Measure: Assess the safety and tolerability of CT-0508 by estimating the frequency and severity of adverse events in subjects with HER2 overexpressing solid tumors.

Primary Outcome 1 - Timeframe: 14 months

Primary Outcome 2 - Measure: Assess the feasibility of manufacturing CT-0508 by describing the percentage of products passing release criteria.

Primary Outcome 2 - Timeframe: 12 months

Primary Outcome 3 - Measure: Assess the safety and tolerability of CT-0508 in combination with pembrolizumab by estimating the frequency and severity of adverse events in subjects with HER2 overexpressing solid tumors (CT-0508 and pembrolizumab substudy only)

Primary Outcome 3 - Timeframe: 14 months

ELIGIBILITY

Inclusion Criteria:
* HER2-positive recurrent or metastatic solid tumors for which there are no available curative treatment options.
* Breast cancer and gastric/gastroesophageal junction cancers must have failed approved HER2-targeted agents.

- * Other HER2-positive tumor types must have failed standard of care therapies, while prior therapy with anti-HER2 drugs is not required.

- * Subject must be willing and able to undergo tumor tissue biopsy procedures

- * Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1

- * Subject has adequate bone marrow and organ function
Exclusion Criteria:
* HIV, active hepatitis B or hepatitis C infection.

- * Diagnosis of immunodeficiency or chronic exposure to systemic corticosteroid therapy or any other form of immunosuppressive therapy

- * Untreated or symptomatic central nervous system (CNS) metastases or cytology proven carcinomatous meningitis.
o Subjects with small, asymptomatic CNS metastases that do not require treatment are permitted to enroll.

- * Left ventricular ejection fraction (LVEF) <50% as determined by ECHO or multiple gated acquisition scan (MUGA)
Other protocol-defined Inclusion/Exclusion may apply.
CT-0508 in Combination with Pembrolizumab Substudy Only:
Exclusion Criteria:
* Subjects with severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients
