Thanks, Robert, and good afternoon, everyone, and thank you for joining us today. As always, we really appreciate your continued support at Celcuity. I am happy to report that over the past few months our team has made significant progress on a variety of fronts to advance the development of gedatolisib. On this call we will review the regulatory status of gedatolisib’s clinical development program, our pivotal phase 3 trial on breast cancer and our recent financing activity. In July, the U.S. Food and Drug administration or FDA granted breakthrough therapy designation to Celcuity's lead drug product candidate gedatolisib, an investigational pan-PI3K/mTOR inhibitor, for the treatment of HR+/HER2- locally advanced, inoperable or metastatic breast cancer that has progressed after treatment with a CDK4/6 inhibitor in combination with a nonsteroidal aromatase inhibitor. Breakthrough therapy designation is intended to expedite the review of drugs that agency believes have significant potential in treating serious diseases with unmet medical needs and offers a potential to receive an accelerated review if relevant criteria are met. We look forward to collaborating closely with the agency as we seek to advance the therapy to the clinic as quickly as possible. Gedatolisib previously received fast track designation from the FDA in January, 2022. In our submission seeking breakthrough status, we provided detailed clinical safety and pharmacological data with a focus on our early phase study, evaluating gedatolisib in combination with palbociclib and fulvestrant in patients with advanced breast cancer whose disease progressed on a CDK4/6 inhibitor. This study reported very promising efficacy with a high objective response rate and extended progression free survival period and safety data that compared favorably to the currently available therapies for advanced breast cancer patients in the second line setting. The initial potential target patient population gedatolisib patients with HR positive versus negative, advanced breast cancers disease progressed during treatment with the CDK4/6. We estimate this represents over 100,000 breast cancer patients globally on an annual basis. Current standard of care for these patients includes endocrine therapies such as fulvestrant, and regimens that combined fulvestrant with either an mTOR specific or a PI3K alpha specific targeted therapy. These therapies offer only modest progression free survival periods and in the case of the approved PI3K alpha inhibitor, a very challenging safety profile. The PIK3 mTOR pathway is considered one of the most important pathways involved in cancer, blockading PI3K mTOR efficaciously and safely though, has been challenging because of its structural complexity and its blankets to key cellular metabolic processes. Gedatolisib inhibits all four class one PI3lK isoforms and the mTOR 1 and mTOR 2 subunits. This is the biologically optimal approach because it limits the potential for cross activation of uninhibited isoforms or subunits and the resulting drug resistance that can occur with PI3K isoforms and mTOR specific inhibitors, completely blockading the pathway also enhances the potential to induce synergistic inhibition with other targeted therapies such as CDK4/6 inhibitors. Gedatolisib differentiated chemical structure and intravenous formulation results in a very favorable pharmacokinetic profile. The drug is potent against the various PI3K isoforms and mTOR subunits at low or sub nanomolar concentrations, and is able to maintain pathway inhibition with a tiny fraction of drug compared to approved oral PI3K inhibitors. This results in a safety profile that compares very favorably against the approved isoform specific PI3K inhibitors. Last, we believe gedatolisib unique properties position to realize the significant potential first envision for PI3K therapies and the pathways critical role in cancer was discovered. To advance the development of gedatolisib we're conducting a pivotal phase three clinical trial known as VICTORIA-1 to evaluate the safety and efficacy of gedatolisib in combination with fulvestrant with or without palbociclib in adults with HR positive, HER2 negatives advanced breast cancer, whose disease progressed while receiving prior CDK4/6 therapy. This open label randomized clinical trial will enroll subjects regardless of PIK3CA status while enabling separate evaluation of subjects according to their PI3K status. The clinical trial protocol we described in May included five arms with three arms evaluating patients lacking PIK3CA mutations, and two arms evaluating patients with PIK3CA mutations. At that time we had received feedback from the FDA on our study design, but we were still waiting to receive feedback from the European Medicines Agency or EMA. And late May we received the most feedback to our protocol which included a recommendation that the study arms for PIK3CA mutated patients mirror the same study arms for PIK3CA non mutated patients. In response to this feedback we modified the protocol to include an additional study arm to evaluate get the list of plus fulvestrant in 50 patients who have PIK3CA mutations. PIK3CA mutated patients will now be randomized on a one to one to one basis to receive either gedatolisib plus palbociclib fulvestrant or the controlled alpelisib fulvestrant. 150 PIK3CA mutated patients are enrolled to the gedatolisib plus fulvestrant arm. Subsequent patients will be then randomized on a one to one basis to receive either gedatolisib plus palbociclib plus fulvestrant or alpelisib fulvestrant. Subjects without confirm PIK3CA mutations will continue to be randomly assigned on a one to one to one basis to receive a regimen of either gedatolisib palbociclib fulvestrant or arm A gedatolisib fulvestrant B fulvestrant arm C. No changes were made to the primary endpoints and we continue to expect data for the PIK3CA non-mutated patients to be available in the second half of 2024 and data for the PIK3CA mutated patients to be available in the first half of 2025. We're also excited to report that the updated clinical trial protocol that includes the additional arm was submitted to the FDA and received no comments an d Central Institutional Review board or IRB approval was received with us remain on track to dosed the first patient in the next few months. Dosing the first patient in any study is a significant milestone. For us, it will be doubly significant since it will trigger the closing of the $100 million private placement we announced earlier this year, provided that as occurs on or before December 31, 2022. Investors in the private placement included Venrock Healthcare Capital Partners, New Enterprise Associates, RA Capital Management, Commodore Capital, Soleus Capital and myself. We also made additional progress strengthening our balance sheet this past week. Our debt financing agreement within Nevada's Capital Partners was amended to provide Celcuity with up to $75 million in term loans, a $50 million increase from the original debt financing agreement. Celcuity received $15 million. At the closing of the original agreement in April 2021. Celcuity will now be able to draw an additional $20 million following the closing of the $100 million private placement. Celcuity will also then be able to draw on two additional tranches of $10 million each and one additional tranche of $20 million upon achievement of certain clinical trial and financing milestones. Celcuity is entitled to make interest only payments through April 25 or if certain conditions are met through April 2026. The loans will mature in April 2027, the sixth anniversary of the initial funding date. Now I'd like to move on to the diagnostics sides of our business. CELsignia, Celcuity 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. Our strategy is to develop companion diagnostics that enable the pharmaceutical company to expand the number of patients eligible to receive their targeted therapy. Our ongoing FACT trials were negatively impacted by COVID-19 related delays during late 2021 and early 2022. Now with a lower COVID case roll load enrollment activities have resumed for these trials and we expect interim results from the FACT-1, 2 trials mid 2023. With that, I'd like to turn the call over to Vicky Hahne to review our financial results.
