"Our collaboration with GT Medical Technologies is an exciting and important opportunity to test the radio-sensitizing effect of Tumor Treating Fields, which will be applied for at least two weeks prior to resection and GammaTile implantation," said William Doyle, Novocure’s Executive Chairman. "This trial is designed to build additional evidence of the effectiveness of Tumor Treating Fields plus radiation therapy and to explore the potential to further extend survival for recurrent GBM patients."

Novocure and GT Medical Technologies plan to conduct a phase 2 pilot study to test the effectiveness and safety of neo-adjuvant TTFields followed by resection, GammaTile Therapy, and adjuvant TTFields for recurrent GBM. The study is designed to enroll approximately 55 patients in the United States. Progression free survival (PFS) for the intent-to-treat population is the primary endpoint of the study. Secondary endpoints include overall survival, PFS for per protocol patients, time to progression, six-month survival rate, one-year survival rate, PFS at six months, and safety.

"GT Medical Technologies is enthusiastic about the potential of these combined therapies," said Matthew E. Likens, President and CEO of GT Medical Technologies. "This trial is a great opportunity to expand care and therapeutic options for recurrent GBM patients. GammaTile delivers 50 percent of the radiation within 10 days of resection, which we believe maximizes patient outcomes while improving local tumor control and access to care. We are pleased to partner with Novocure in this pursuit."

About Tumor Treating Fields

Tumor Treating Fields, or TTFields, are electric fields that disrupt cancer cell division.

When cancer develops, rapid and uncontrolled division of unhealthy cells occurs. Electrically charged proteins within the cell are critical for cell division, making the rapidly dividing cancer cells vulnerable to electrical interference. All cells are surrounded by a bilipid membrane, which separates the interior of the cell, or cytoplasm, from the space around it. This membrane prevents low frequency electric fields from entering the cell. TTFields, however, have a unique frequency range, between 100 to 500 kHz, enabling the electric fields to penetrate the cancer cell membrane. As healthy cells differ from cancer cells in their division rate, geometry and electric properties, the frequency of TTFields can be tuned to specifically affect the cancer cells while leaving healthy cells mostly unaffected.

Whether cells are healthy or cancerous, cell division, or mitosis, is the same. When mitosis starts, charged proteins within the cell, or microtubules, form the mitotic spindle. The spindle is built on electric interaction between its building blocks. During division, the mitotic spindle segregates the chromosomes, pulling them in opposite directions. As the daughter cells begin to form, electrically polarized molecules migrate towards the midline to make up the mitotic cleavage furrow. The furrow contracts and the two daughter cells separate. TTFields can interfere with these conditions. When TTFields are present in a dividing cancer cell, they cause the electrically charged proteins to align with the directional forces applied by the field, thus preventing the mitotic spindle from forming. Electrical forces also interrupt the migration of key proteins to the cell midline, disrupting the formation of the mitotic cleavage furrow. Interfering with these key processes disrupts mitosis and can lead to cell death.

TTFields is intended principally for use together with other standard-of-care cancer treatments. There is a growing body of evidence that supports TTFields’ broad applicability with certain other cancer therapies, including radiation therapy, certain chemotherapies and certain immunotherapies. In clinical research and commercial experience to date, TTFields has exhibited no systemic toxicity, with mild to moderate skin irritation being the most common side effect.

Fundamental scientific research extends across two decades and, in all preclinical research to date, TTFields has demonstrated a consistent anti-mitotic effect. The TTFields global development program includes a broad range of clinical trials across all phases, included four phase 3 pivotal trials in a variety of tumor types. To date, more than 18,000 patients have been treated with TTFields.

Non-specific degradation of endocytosed cancer antigens by endo-lysosomal organelles in dendritic cells (DCs) is a major limitation in the field of cancer vaccination. Defence AccuVACTM addresses this with its engineered novel antigen formulation. The AccuVACTM protects endocytosed antigen from non-specific endosomal degradation by promoting its escape via endosomal membrane disruption. As such, endocytosed antigens accumulate – in their closest native state – in the cytosol of DC cells consequently resulting in efficient antigen crosspresentation to responding immune cells.

AccuVACTM dramatically improved protein processing and cross-presentation by ex vivo developed monocyte-derived DCs, which elicited potent CD4 and CD8 T-cell responses compared to the use of naked antigen. The net outcome culminates into effective anti-tumoral responses curing 70% of animals with pre-established solid tumors.

"The solid results of the AccuVACTM study demonstrates how this strategy can be positively adapted to engineered universal DC vaccines. This puts Defence and its technology on the path for future development of universal therapeutic vaccines for cancer and infectious diseases vaccines", says Mr. Plouffe, CEO of Defence Therapeutics.

Lipid metabolism has been reported to play a critical role in various cancers. Fatty acid synthase (FASN) is one of the most important proteins which regulate lipid metabolism. Many solid and hematopoietic tumors overexpress FASN, including rGBM, non-small cell lung, breast, ovarian, prostate, colon, pancreatic cancers, and non-Hodgkin lymphoma.

ASC40 (known as TVB-2640 outside China) is a potent, selective and safe oral small molecule inhibitor of FASN. The positive results were demonstrated from the investigator sponsored Phase II trial of ASC40 (TVB-2640) in combination with bevacizumab in patients with first relapse of high-grade astrocytoma i.e. rGBM, which was completed in the United States (ClinicalTrials.gov Identifier: NCT03032484). The data from this Phase II trial have shown that the overall response rate (ORR) for ASC40(TVB-2640) plus bevacizumab was 65% including the complete response (CR) of 20% and partial response (PR) of 45%. Furthermore, the data indicate that the progression-free survival at six months (PFS6) observed for ASC40 (TVB-2640) plus bevacizumab was 47%, representing a statistically significant improvement in PFS6 over historical bevacizumab monotherapy (BELOB16%, P=0.01). ASC40 (TVB-2640) in combination with bevacizumab was safe and well tolerated in such patient population.

"Since the announcement on March 30 this year for investment escalation in R&D of cancer lipid metabolism and oral checkpoint inhibitors, this is a key step forward for the Company’s oncology pipeline." said Dr. Jinzi J. Wu, Founder, Chairman and CEO of Ascletis.
