Company Evaluating NT219 as Monotherapy Treatment of Advanced Solid Tumors and in Combination with Cetuximab for the Treatment of Recurrent and/or Metastatic Solid Tumors and Head and Neck Cancer

Preliminary Data from the First Part of this Study Anticipated to be Available in Second Half of 2021

TEL AVIV, Israel, July 09, 2020 (GLOBE NEWSWIRE) -- Kitov Pharma Ltd. (“Kitov”) (NASDAQ/TASE: KTOV), a clinical-stage company advancing first-in-class therapies to overcome tumor immune evasion and drug resistance, today announced the initiation of the first study site in a Phase 1/2 clinical trial of NT219, a dual inhibitor, novel small molecule targeting IRS1/2 and STAT3, important oncogenic drivers and major drug resistance pathways in many hard-to-treat cancers.

“The initiation of this Phase 1/2 clinical trial is a key advancement in our NT219 development program,” said Bertrand Liang, M.D., Ph.D., Chief Medical Officer of Kitov. “In preclinical studies, NT219 demonstrated impressive tumor growth inhibition, both as monotherapy as well as in combination with multiple anti-cancer drugs, and we are excited to further evaluate its potential in the clinic.” Up to eight sites are planned to be initiated in the U.S. and Canada over the next few months. Availability of preliminary data from the first part of this study is anticipated in the second half of 2021.

“Identifying potential treatment options for resistant cancers is of paramount importance, so I am pleased to be participating in this important clinical trial,” said Ezra Cohen M.D., Chief, Division of Hematology-Oncology and Associate Director, Translational Science at Moores Cancer Center in San Diego, CA, and Lead Principal Investigator of the study.  “Based on the compelling anti-tumor activity demonstrated by NT219 in pre-clinical studies, we believe this drug candidate has the potential to be a safe and effective therapy for multiple cancers. I look forward to dosing of the first patients in this trial shortly.”

The Phase 1/2 trial is evaluating NT-219 as monotherapy treatment of advanced solid tumors, as well as in combination with cetuximab, an epithelial growth factor receptor (EGFR) blocking monoclonal antibody, for the treatment of recurrent and/or metastatic solid tumors and head and neck cancer or colorectal adenocarcinoma. The primary objectives of the open-label Phase 1/2 trial are to evaluate safety, assess pharmacokinetics, identify the recommended dose to be studied in the Phase 2 portion, and establish preliminary efficacy of NT219. The Phase 1 portion of the study will encompass a dose escalation evaluation of NT219 monotherapy administered weekly in patients with refractory advanced solid tumors. Upon reaching the third dose level of NT219, a second cohort of patients, with recurrent and/or metastatic squamous cell carcinoma of the head and neck or colorectal adenocarcinoma, will be administered weekly with NT219, dose escalated, in combination with cetuximab. Upon completion of the monotherapy and combination therapy Phase 1 portions of the trial and establishment of the recommended Phase 2 dose for NT219, Kitov plans to commence an expansion Phase 2 component of the study at that dose of NT219 in combination with cetuximab in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck. The trial will also include exploratory evaluations of different potential biomarkers in patient tumors and serum.

The study is initially expected to be conducted at eight medical centers, including six in the U.S. and two in Canada, with additional centers potentially joining for the expansion cohort.
