Thank you, Robert. Good afternoon, everyone, and thank you for joining us today. As always, we appreciate your continued support of Celcuity. On this call, we'll update you on our third quarter financial results, the status of our gedatolisib clinical development program and an update on our CELsignia companion diagnostic activities. Vicky will follow my comments with a discussion of our financial results, and then we'll open up the line for questions. As most of you may know, Celcuity took a transformational step in April this year, when we licensed the pan PI3K/mTOR inhibitor gedatolisib from Pfizer. We took this step because of the significant potential that a well-tolerated pan PI3K/mTOR inhibitor offers to improve outcomes for patients with many different tumor types. This potential reflects the central role for active PI3K/mTOR signaling plays in the development proliferation of many tumor types, blockading PI3K/mTOR efficaciously and safely though is challenging, because of its structural complexity and its linkage to key cell metabolic processes. While the optimal approach to inhibiting PI3K/mTOR requires targeting five different subunits, doing so has until gedatolisib’s development resulted in drugs that patients could not tolerate. We believe gedatolisib was the first PI3K/mTOR inhibitor that combines high potency against all five subunits with a safety profile that compares very favorably against approved isoform specific PI3K inhibitors. Thus, we believe gedatolisib is uniquely positioned to realize the significant potential first envision for PI3K therapies when the pathways critical role in cancer was discovered. We’re currently developing gedatolisib to treat patients with ER positive HER2 negative advanced or metastatic breast cancer. We estimate that over 100,000 breast cancer patients globally would potentially be eligible to receive gedatolisib if approved. Given the broad role, PI3K/mTOR signaling has been demonstrated to play in a broad range of tumor types. We also believe we have a substantial opportunity to develop additional indications outside of breast cancer. During the quarter, we completed the transfer of regulatory, clinical trial and safety reporting responsibilities for gedatolisib from Pfizer to Celcuity ahead of schedule. For our ongoing Phase 1b breast cancer clinical trial, we're now working with the participating sites to transition the 14 patients who are continuing to receive gedatolisib treatment to an updated clinical trial protocol. This ongoing clinical trial is evaluating gedatolisib in a combination with the CDK4/6 inhibitor Ibrance and two different Endocrine therapies. We're very pleased that updated data from our ongoing Phase 1b clinical trial for patients will be presented at the San Antonio Breast Cancer Symposium during a Spotlight Poster Discussion Session on December 10, 2021. Dr. Rachel Layman, an oncologist at the University of Texas MD Anderson Cancer Center who was a principal investigator for the clinical trial, will be the presenter. Our preparations to initiate a Phase 3 clinical trial evaluating gedatolisib in combination with palbociclib and fulvestrant, which is an Endocrine therapy in patients with advanced breast cancer are well underway. We had engaged the CRO and other critical vendors started the process of site identification and qualification and received commitments from a number of globally recognized breast cancer KOLs to serve as members of our trials steering committee. Our meeting with the FDA is scheduled and subject to their feedback, we continue to expect to activate this clinical trial in the first half of 2022. We also began evaluating and prioritizing new potential indications for gedatolisib. This evaluation includes assessment of previous trials for other PI3K and mTOR inhibitors review of tumor microenvironment factors related to PI3K/mTOR activity and identification of non-clinical and clinical evidence of pathways that may cooperate with PI3K/mTOR. Our goal is to develop a lifecycle development plan in the first half of 2022 that will guide our long-term plans for gedatolisib. As we've previously discussed, our assessment of different PI3K and mTOR inhibitors using our CELsignia platform, let us initially to approach Pfizer about our interest in pursuing a collaboration to evaluate gedatolisib subsequent to that initial internal study and as part of our due diligence on gedatolisib’s mechanism of action, we conducted additional studies to evaluate gedatolisib in a PI3K inhibitor in breast and ovarian patient tumors using our CELsignia platform. We presented the results of these studies at the AACR annual meeting this past April. The studied demonstrated the value of leveraging our CELsignia platform to gain valuable insights about drug development opportunities, with us is part of our lifecycle development planning efforts. We are conducting additional investigations using our CELsignia platform to support our assessment of different indications for gedatolisib. Now I'd like to move on to the diagnostics side of our business. CELsignia Celcuity’s third generation diagnostic platform identifies the underlying cellular activity, dysregulated pathway signaling that may be driving a patient's tumor. So that a matching targeted therapy can be identified. Since dysregulated signaling is too complex for molecular tests to characterize in most cases, our platform can identify new treatment options for patients who lack actionable molecular biomarkers. Our strategy is to develop companion diagnostics that enable a pharmaceutical company to expand the number of patients eligible to receive their targeted therapy. To achieve this, we're collaborating with pharmaceutical companies to evaluate the efficacy of their targeted therapies and patient populations selected by a CELsignia pathway activity test. The clinical trial results are favorable. These collaborations may lead to advancement of a new indication that expands the market for targeted therapy. In October, Celcuity entered into a clinical trial collaboration with the University of Rochester Wilmot Cancer Center and Puma Biotechnology. This open-label Phase 2 trial will evaluate the efficacy and safety of Puma's pan-HER inhibitor, NERLYNX or neratinib, and a chemotherapy, capecitabine, in previously treated patients selected with Celcuity CELsignia HER2 activity tests who have metastatic HER2 negative breast cancer with brain metastasis. This will be our first collaboration study metastatic breast cancer patients with brain metastasis, patient population with an unmet and challenging medical need. But we're hopeful CELsignia may allow us to identify much needed new treatment options for them. Based on estimates in patient enrollment rates, Celcuity expect to obtain interim results 12 to 15 months after initiation of the trial followed by the final results 12 to 15 months later. Enrollment is planned to begin by mid-2022. We now have six clinical trial collaborations in place. The ongoing FACT-1 and FACT-2 trials that Celcuity is conducting or evaluating anti-HER2 therapies in early stage of HER2 negative breast cancer patients. The goal of each of these trials is to demonstrate the breast cancer patients identified by our CELsignia HER2 pathway activity tests obtain a higher rate of pathological complete response to neoadjuvant anti-HER2 drug treatment than from current standard of care chemotherapies. Patients who receive a pathological complete response to neoadjuvant drug treatment are less likely to have their cancer recur. So we believe our CELsignia tests can play a significant role in extending the lives of many breast cancer patients. Enrollment in both the FACT-1 and FACT-2 trials though were negatively impacted by COVID-19 related delays during the third quarter. Hospitalizations of patients with COVID-19 increased dramatically during this period, which will let hospitals to reduce clinical trial related activities, especially those that require a screening step such as CELsignia. We now expect interim results from in FACT-1 and FACT-2 trials in the second half of 2022. This is later than our previous expectation of interim results in the first quarter of 2022. Nevertheless, we're excited about these collaborations and the opportunity to work with some of the world's most prominent cancer research centers. We have additional collaborations discussions in progress, and our goal is to announce new agreements in the coming months. Now I'd like to turn our call over to Vicky Hahne to review our financial results.
