Analyst · Craig-Hallum. Please go ahead. Your line is open
Thank you and good afternoon, everyone. We announced the financial results of our first quarter ended March 31, 2018 a few minutes ago. Before we begin though, I'd like to remind listeners that our comments today will include some forward-looking statements. These statements involve a number of risks and uncertainties which are outlined in today's press release and in our reports and filings with the SEC. Actual results may differ materially from those in the forward-looking statements. On this call, we'll also refer to non-GAAP financial measures. You can find a table reconciling the non-GAAP financial measures to GAAP financial measures in our earnings release for the first quarter ended March 31, 2018, which was included in today's press release. Today's press release is available on our website, www.celcuity.com, under the Investors section. I also have on the call with me today Vicky Hahne, our CFO. I'd first like to make some comments on our first quarter results, Vicky will follow with more details on a few items, and then we'll open up the like for questions. As we've previously disclosed, completing development in additional signaling pathway test for breast cancer is one of our primary objectives in 2018. And I'm excited to announce that we completed development of our second CELx test for breast cancer during the first quarter of 2018. This new test evaluates independent c-Met pathway signaling activity and its involvement with HER family signaling in HER2-negative breast cancer tumor cells. Abnormal c-Met signaling, including cross-talk between c-Met and HER family receptors, has long been suspected of playing a role in a variety of cancer types. To treat c-Met involved cancer, a number of pharmaceutical companies have developed c-Met targeted therapies. Today though, clinical trials evaluating investigational anti c-Met therapies alone and in combination with other targeted therapies have produced mostly negative results. And since these subjects enrolled in these trials were primarily ones with c-Met protein over expression or gene amplification, I'll suggest that alternative biological factors should be measured such as c-Met signaling activity to identify patients eligible for treatment with c-Met therapies. We intend to combine the c-Met signaling function test with our current HER2 signaling function test to create the CELx Multi-Pathway or MP test. With this next generation CELx test, we plan to provide an analysis of HER1, HER2, HER3, and c-Met signaling activity with a single patient tumor specimen. We demonstrated the role of abnormal c-Met signaling as a cancer driver in breast cancer in a mouse xenograft study performed at the University of Minnesota. A breast cancer cell line determined by the CELx MP test to have normal HER2 signaling, abnormal HER1 signaling and abnormal c-Met signaling was studied. Mice were randomly assigned to either a control group or a treatment group that received either the pan-HER inhibitor, neratinib, the c-Met inhibitor, tepotinib, or the combination of neratinib and tepotinib. We measured tumor volumes receiving both neratinib and tepotinib in the control. We note that the tumor volumes in the mouse arm receiving both neratinib and tepotinib shrank significantly more than the tumors in the study arms that received neratinib or tepotinib alone. In the xenograft, tumor reduction results were consistent with those produced by our CELx MP test. In an internal study with breast tumor specimens obtained from 74 HER2-negative breast cancer patients, we found that approximately 15% to 20% of them had abnormal c-Met signaling that was co-activated with abnormal HER1 signaling. Our internal studies further characterize the co-involved [ph] nature of the signaling activity and the efficacy of several c-Met and HER family drugs. And we believe this provides strong evidence that the sub-group of HER2-negative breast cancer patients with these abnormalities may respond treatment with the combination of HER family and c-Met inhibitors. We will see collaborations with pharmaceutical companies to field clinical trials that evaluate the efficacy of combining HER family inhibitors and c-Met inhibitors in breast cancer patients who gave abnormal c-Met and abnormal HER1 pathway activity. The FDA has approved two c-Met inhibitors and six HER family inhibitors for cancer treatment, there are number of additional investigational c-Met and HER family inhibitors being evaluated in current clinical trials. Several pharmaceutical companies possess both the c-Met and the HER family inhibitor. And through collaborations, we hope to help these pharmaceutical companies obtain new indications for targeted therapies to treat this new cancer sub-type. We are also excited about the quality of sites for the clinical trial we are fielding in collaboration with the NSABP Foundation and Genentech. This clinical trial, which we refer to as FACT 1 is designed to evaluate the efficacy of two of Genentech's HER2 drugs, Herceptin and Perjeta in HER2-negative breast cancer patients selected by our CELx HER2 signaling function test. We believe that we'll get interim results from this trial in the first or second quarter of 2019, instead of the end of 2018, as originally anticipated. The longer timeline is primarily due to more sites opting to rely on their internal institutional review board or IRB, instead of the central IRB that has already approved our clinical trial protocol. We originally anticipated that approximately 80% of the expected sites would utilize the central IRB, and we now believe that number is approximately 25% of sites. The internal IRB process typically takes several months, and which will cause the bulk of our sites to begin enrolling patients later than originally projected. Final results would still be expected approximately six months following interim results. Finally, we continue to make progress developing tests for new tissue types. And our goal, as we previously stated, is to complete the development of these tests by the end of calendar year 2018. And these tests will further expand the range of collaboration opportunities, we can pursue with pharmaceutical companies. So overall, we're very excited about the progress we made during the quarter. I'd like to turn it now to Vicky, who will give you a rundown briefly on our financial results.
