Tiziana Life Sciences announces presentation of StemPrintER, a superior prognostic test as compared to Oncotype DX to predict breast cancer

• StemPrintER Outperforms Oncotype DX in analysis with 800+ samples from ER+/HER2- postmenopausal breast cancer patients
  
• SPARE Model is up to 40-50% more accurate than standard clinical markers in analysis with 1800+ samples for prediction of distant metastasis

NEW YORK and LONDON, May 29, 2020 (GLOBE NEWSWIRE) -- Tiziana Life Sciences plc (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company focused on innovative therapeutics for oncology, inflammation and infectious diseases, announces today results, from a poster selected for discussion session at the American Society of Clinical Oncology (ASCO) Virtual Conference, demonstrating the superiority of StemPrintER stem cell based genomic prognostic tool versus the market leader, Oncotype DX, in predicting recurrence in ER+/HER2- postmenopausal breast cancer patients. A second poster describing results on prediction of distant recurrence using a next generation StemPrintER model, named SPARE, presented in a separate ASCO session, showed even more refined accuracy than standard clinicopathological markers in predicting risk of distant recurrence. Both posters were authored by a team of scientists from the European Institute of Oncology in Milan, and the head-to-head comparison of StemPrintER with Oncotype DX was conducted in collaboration with the Royal Marsden Hospital and Queen Mary University in London.

As announced previously, the Company intends to demerge its StemPrintER and SPARE (together "StemPrintER") genomics-based personalized medicine businesses into a separate company and effect a capital reduction to facilitate the spin-out and listing of StemPrintER as an independent entity.

Major Highlights of Results

1. The first poster, which was also part of a discussion session, “Comparison of StemPrintER, a Novel Biology-based Genomic Predictor of Distant Recurrence in Breast Cancer, with Oncotype DX in the TransATAC cohort,” shows that StemPrintER
   
   
   • Outperforms Oncotype DX in 10-year risk prediction in more than 800 ER+/HER2- postmenopausal breast cancer patients in the analysis, including in lymph node-negative (N0) and 1 to 3 lymph node-positive (N1-3) patients¹.
   • Significantly (p<0.0001) stratifies high vs. low risk groups when adjusted for clinical parameters as expressed by clinical treatment scores (CTS).
