This is the second clinical update following the introduction of TSE (Tumour Specific Electroporation™) in the curative treatment line of Head and Neck (H&N) cancer at AIIMS Jodhpur. In this update, CMO Suhail Mufti provides insights into the long-term clinical study objectives and key milestones.

Clinical Trial Progress in University Hospital in Jodhpur India, non-sponsored trials:

1. Patient enrolment began as scheduled, following the Ethics Committee approval of the revised clinical study protocol, as publicly announced on November 29, 2023.
2. The latest protocol amendment added Arms B and C to the study, including patients with unresectable locoregional recurrence of Head and Neck (H&N) cancer. Arm B of the study protocol includes patients eligible for radiotherapy, while Arm C involves patients eligible for chemotherapy, targeted therapy, immunotherapy, or a combination with medical treatment. Arm A is unchanged and includes patients with recurrence after surgery, radiation and chemotherapy.
3. The delay in enrolment due to administrative changes at the research institution, which are beyond ChemoTech's control, are of course deeply regrettable. However, we are optimistic that these adjustments will ultimately benefit the research process. We appreciate your patience as we work through this and remain committed to moving the project forward efficiently.

The first patient under Arm B of the revised protocol has completed TSE therapy, marking the first time TSE was used before other second-line treatments. The study team reported a nearly 50% reduction in tumour size, allowing the patient to proceed with radiotherapy without needing surgery. A case study on this is being prepared by the research team.

Future targets for the AIIMS Trial

• Data collection and biomarker analysis in the ongoing clinical trial continues.
• A breast cancer protocol has been reviewed and is awaiting discussion by the Ethics Committee.
• AIIMS research teams has shown interest in pilot studies for deep-seated tumours. Updates will follow.
• A case series for routine cases outside the clinical trial at AIIMS is completed and under peer review. Further updates will be provided soon.

Clinical Strategy and Achievements

The clinical development goals for TSE extend beyond demonstrating its effectiveness in treating superficial tumours and providing palliative care. The current focus is on utilizing TSE in earlier, curative cancer treatments in combination with other therapies.

The table below highlights the key milestones achieved in translating the scientific knowledge of TSE into clinical practice, ensuring compliance with Regulatory Affairs and Good Clinical Practice (GCP) standards.
