Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - MEDI7247

Experimental: NSCLC-Sq/HNSCC - Patients with advanced or metastatic NSCLC-Sq or HNSCC who have recurrence after, or are refractory or intolerant to standard therapy, including at least one prior standard of care regimen (platinum-based for HNSCC). PDL-1 positive patients should have received previous PD-1 or PD-L1 inhibitor where available.

Experimental: Small Cell Lung Cancer - Patients with advanced SCLC who have recurrence after, or are refractory or intolerant to standard therapy, including at least one prior standard of care regimen.

Experimental: Colorectal Cancer - Patients with metastatic adenocarcinoma of the colon or rectum who have received and have progressed, or have documented intolerance, on prior thymidylate synthase inhibitor (eg, 5-fluorouracil (5-FU), capecitabine, raltitrexed, tegafur-uracil (UFT), irinotecan, and oxaliplatin for metastatic disease. If patients progress within 6 months of their last dose of adjuvant therapy this should be considered as a line of therapy in the metastatic setting. Patients with known RAS wildtype tumors must have received and progressed, or have documented intolerance, on anti-EGFR antibody. Patients with microsatellite instability-high or deficient mismatch repair tumors, must have received and progressed, or have documented intolerance on a PD-1 inhibitor, or PD-1 inhibitor plus cytotoxic T-lymphocyte antigen-4 inhibitor treatment where available.

Experimental: Pancreatic Ductal Adenocarcinoma - Patients with unresectable, locally advanced or metastatic PDAC who have recurrence after, or are refractory or intolerant to standard therapy, including at least one prior line of treatment.

Experimental: Metastatic Castration-Resistant Prostate Cancer - Patients with mCRPC who have received prior treatment with abiraterone or enzalutamide, with or without a prior taxane-based chemotherapy in the mCRPC setting.

Experimental: Other advanced/metastatic target expressing solid tumors - Patients with advanced or metastatic solid tumors not defined by other treatment arms who have positive expression of the protein target and have exhausted all approved therapies


Treatment: Drugs: MEDI7247
Subjects with advanced solid tumors will enroll into the respective arms to receive Medi7247 IV at prescribed dose and schedule

Summary
Brief summary
To assess safety and tolerability, describe the dose-limiting toxicities, assess the
preliminary antitumor activity, determine the maximum tolerated dose (MTD) or the highest
protocol-defined dose (maximum administered dose) in the absence of establishing the MTD, and
a recommended dose for further evaluation of MEDI7247 in patients with selected advanced or
metastatic solid tumor malignancies that have received at least 1 prior line of treatment.
