Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in T-cell therapy to treat cancer, today announced that it has initiated the first site for its MAGE-A4 SPEAR T-cell study in patients with multiple malignant solid tumors. This study is now open for enrollment.

This is Adaptimmune’s third wholly-owned therapeutic candidate to enter clinical trials. The Company already has ongoing studies to evaluate its T-cell therapies targeting the MAGE-A10 cancer antigen in patients with non-small cell lung cancer, urothelial cancer, melanoma, or head and neck cancers; and AFP in patients with hepatocellular carcinoma.

“We are excited to initiate this study to evaluate our MAGE-A4 T-cell therapeutic candidate in patients with multiple malignant solid tumors,” said Rafael Amado, Adaptimmune’s Chief Medical Officer. “Preclinical evaluations of our MAGE-A4 affinity matured T-cell receptor show optimized targeting of, and specificity for, MAGE-A4 expressing cancer cells. MAGE-A4 is among the most commonly expressed cancer embryonic antigens; therefore, we have the opportunity to evaluate the potential of this promising therapy in a wide range of cancers.”

This is a Phase I, open label, dose escalation study designed to evaluate the safety and anti-tumor activity of Adaptimmune’s MAGE-A4 therapeutic candidate in patients who are HLA-A*02 positive and have inoperable locally advanced or metastatic melanoma, urothelial, head and neck, ovarian, non-small cell lung, esophageal, and gastric cancers expressing MAGE-A4. The study will enroll up to 32 patients. The primary objective of the study is to evaluate the safety and tolerability of MAGE-A4 SPEAR T-cell therapy. Additional objectives include anti-tumor activity, persistence of genetically modified cells in the body, and evaluation of the phenotype and functionality of genetically modified cells isolated from peripheral blood or tumor post infusion.
