TGX-007 / Trogenix - LARVOL DELTA

An AAV-1 mediated dual-payload gene therapy for high grade glioma (SNO 2025) - "These findings provide the rationale for a first-in-human, phase I/II Bayesian optimal interval study to establish the safety and OBD of TGX-007 and to assess preliminary efficacy of TGX-007 in patients with newly-diagnosed GBM or with first radiological progression of previously treated GBM. TGX-007 will be administered with intra-operative MRI guidance via convection enhanced delivery. Patients will then receive 2 weeks valaciclovir (HSVtk substrate) prior to surgical debulking, then standard-of-care treatment."

ADePT A phase I/II study of an AAV-1 mediated dual-payload gene therapy in patients with high grade glioma (SNO 2025) - "TGX-007 delivers dual genetic payloads, via AAV-1 mediated delivery, which are activated only in tumour cells under control of this SSE...HSV-tk is an enzyme that converts the nucleoside analogue valaciclovir to a cytotoxic molecule, resulting in cell death...Primary endpoints are: Phase I - safety and tolerability, OBD determination; Phase II – OS rate at 12 months (newly-diagnosed population) and 6 months (recurrent population). Secondary and exploratory endpoints include PFS, viral shedding, proof-of-mechanism within tumour tissue."
