Analyst · Jefferies
Thank you, Robert, and 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 first quarter financial results and key activities over the next few months. In particular, we'll review the financing transaction we announced this morning and the status of the clinical development program and pivotal Phase III trial design for gedatolisib. Today, we announced that we entered into a definitive securities purchase agreement with a premier group of biopharmaceutical investors in a private placement that is expected to result in aggregate proceeds to Celcuity of $100 million. Venrock Healthcare Capital Partners is the lead investor. Commodore Capital, New Enterprise Associates, RA Capital Management, Soleus Capital and I are also participating. Investors will purchase shares of common stock and preferred stock at a price per share of $5.75, which is on an as converted to common stock basis. For each share of common stock and each 1/10 of a share of preferred stock purchase, investors will receive a warrant initially exercisable for preferred stock equivalent to 0.4 shares of common stock on an as-converted basis. The exercise price of the warrants will be at a 40% premium to the price paid by investors for the initial shares of common stock purchased in the private placement. The preferred stock will be convertible into common stock at the holder's election, subject to certain limitations such as beneficial ownership and the approval by the company's stockholders to increase the number of authorized shares of common stock sufficient to cover the shares of common stock issuable. The warrants are initially exercisable for preferred stock and will convert into warrants to purchase common stock if the proposed increase in the company's authorized common stock is approved by stockholders. The closing of the private placement is expected to occur shortly after the first patient enrolled in our forthcoming Phase III study, VICTORIA-1, receives their first dose of treatment at a clinical site located in the United States, provided that this occurs before December 31, 2022. You'll be able to find additional details regarding the private placement in a Form 8-K that we will soon file with the SEC. We're very pleased to have attracted such a well-regarded group of investors in this very difficult equity capital market. The erosion in the value of clinical stage biopharmaceutical companies over the past 6 months and the corresponding drop in financing activity creates significant uncertainty for companies like Celcuity. This uncertainty in turn can significantly undermine the company's ability to implement its clinical development programs. In light of the uncertainty this challenging capital market creates, we concluded that strengthening our balance sheet was paramount. With the capital we expect to raise in this transaction, we believe we significantly enhance our ability to develop gedatolisib as a new therapeutic option for cancer patients and to create value for our shareholders. Gedatolisib targets PI3K/mTOR, which is considered one of the most important and complex pathways involved in cancer. Blockading PI3K/mTOR efficaciously and safely though, has been challenging because of its structural complexity and its linkage to see key cellular metabolic processes. Gedatolisib inhibits all 4 Class I PI3K isoforms, in mTOR1 and mTOR2. This is the optimal approach, biologically, because it avoids the cross activation of uninhibited subunits and resulting drug resistance that can occur with PI3K isoform or 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's differentiated chemical structure and intravenous formulation results in a very favorable pharmacokinetic profile. The drug is potent at low or sub-nanomolar concentrations and can 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 approved isoform-specific PI3K inhibitors. Thus, we believe gedatolisib's unique properties position us to realize the significant potential first envisioned for PI3K therapies when the pathways critical role in cancer was discovered. The initial potential target population for gedatolisib patients with HER -- HR-positive HER2-negative advanced breast cancer whose disease progressed during treatment with a CDK4/6 therapy. We estimate this represents over 100,000 breast cancer patients globally on an annual basis. To advance the development of gedatolisib in March, we announced the trial design for VIKTORIA-1, a pivotal Phase III clinical trial to evaluate the safety and efficacy of gedatolisib in combination with fulvestrant with or without palbociclib in adults with HR-positive, HER2-negative 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 PIK3CA status. Subject to meet eligibility criteria and do not have confirmed PIK3CA mutations will be randomly assigned on a 1:1:1 basis to receive a regimen of either gedatolisib, palbociclib and fulvestrant in Arm A; gedatolisib and fulvestrant in Arm B; or fulvestrant in Arm C. Subjects who meet eligibility criteria and have confirmed PIK3CA mutations will be randomly assigned on a 1:1 basis to receive a regimen of either gedatolisib, palbociclib and fulvestrant in Arm D; or alpelisib and fulvestrant in Arm E. We are receiving the supply of palociclib for this trial from Pfizer at no cost to Celcuity. The primary endpoints of the study are progression-free survival for a RECIST 1.1 criteria, as assessed by blinded independent central review. The primary PFS end points will be evaluated separately in subjects who lack PIK3CA mutations and in those who have PIK3CA mutations. This multicenter international trial is expected to enroll patients to clinical sites across the U.S., Europe and Asia. We expect to activate the VIKTORIA-1 study in mid-2022 and that the -- the first patient receiving their first dose is expected to occur 6 to 10 months later. There are roughly twice as many patients who lack PIK3CA mutations as those that have them. And therefore, PFS for the subjects lacking PIK3CA mutations will be available earlier than the data from those who have PIK3CA mutations. As a result, we expect that the primary analysis for PIK3CA non-mutated patients in Arms A, B and C will be available in the second half of 2024, and we expect data for the PIK3CA mutated patients from Arms D and E to be available in the first half of 2025. There are limited options with limited efficacy for patients whose disease progresses on a CDK4/6 inhibitor. Current standard of care treatment includes either a selective estrogen receptor degrader, or SERD, such as fulvestrant; or a regimen that combines an mTOR or PIK3 alpha targeted therapy with an endocrine therapy. Finding more effective treatment for these patients is a significant unmet need. To support our development efforts, we received fast track designation for gedatolisib for the treatment of patients with HR+, HER2-negative advanced breast cancer in January. Fast Track designation is granted by the FDA for products which demonstrates the potential to address a serious unmet medical need. This designation will enhance our ability to interact frequently with the FDA to discuss our development plan. Now I'd just like to take a few moments to discuss the diagnostic sides of our business. CELsignia, our third-generation diagnostic platform, identifies the underlying cellular activity, this regulated 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 a 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 early 2022. Now with the lower COVID case load enrollment activities are resuming for these trials, and we expect to receive interim results from the FACT-1 and FACT-2 trials in the first half of 2023. I'd like now to turn the call over to Vicki Hahne, our CFO, to review our financial results.
