Dr. Scott Koenig
Thank you, Jim. In the past few months, we demonstrated our ability to generate nondilutive capital via partnering efforts, which enabled us to collect $30 million in milestone payments from Incyte and the subsequent receipt of the $60 million upfront payment from Gilead. We are very excited to advance MGD024 in collaboration with Gilead. Also, we continue to operationalize the TAMARACK study of MGC018, which has a new name vobramitamabduocarmazine in prostate cancer and believe we should be able to dose our first patient in the study by year-end. Finally, with enrollment completed in the monotherapy dose expansion study of lorigerlimab, we look forward to sharing clinical data in first quarter of 2023. With that backdrop, let me walk you through updates on our portfolio of investigational clinical molecules starting with vobramitamabduocarmazine or MGC018, or ADC designed to deliver a DNA-alkylating duocarmycin cytotoxic payload to tumors expressing B7-H3. B7-H3 is a member of the B7 family of molecules involved in immune regulation. Vobramitamab, duocarmazi, was designed to take advantage of this antigen's broad expression across multiple solid tumor types. We continue to make progress as we operationalize the TAMARACK study. We've begun initiating clinical sites and expect to start the TAMARACK study by year-end with anticipation of interim data from the Phase II portion of the study in 2024. Next, let me update you on lorigerlimab. We continue to dose patients in the Phase I dose escalation combination study of vobramitamabduocarmazine with lorigerlimab in patients with advanced solid tumors, including renal cell carcinoma, pancreatic cancer, ovarian cancer, patocellular carcinoma, mCRPC and melanoma. You may recall that based on data from our preclinical studies, antitumor activity with vobramitamabduocarmazine, may be enhanced by combination therapy with an anti-PD-1 agent without significant incremental toxicities. During the second quarter, we completed enrollment of the Phase I/II dose expansion study with lorigerlimab as monotherapy in cohorts of patients with microsatellite stable colorectal cancer, mCRPC, melanoma and checkpoint-naive non-small cell lung cancer. Many patients are still on study. And while we will wait to provide a clinical update on this study in the first quarter of 2023, I'll mention that we're very encouraged by what we've seen so far. We look forward to sharing data with you in early 2023. Next up, MGD024 is our next-generation bispecific CD123 x CD3 DART molecule that incorporates the CD3 component designed to minimize cytokine-release syndrome, while maintaining anti-tumor cytolytic activity and permitting intermittent dosing through a longer half-life. Our Phase I dose escalation study of MGD024 is ongoing in patients with CD123-positive relapsed or refractory hematologic malignancies, including acute myeloid leukemia and myelodysplastic syndromes. Of course, we're thrilled to have Gilead as a collaboration partner to advance MGDO24. Last month, we entered an exclusive option and collaboration agreement with Gilead to develop MGD024 and up to 2 additional bispecific research programs in oncology. The agreement grants Gilead the options still had the option to an exclusive license to MGDO24. As part of the agreement, Gilead paid us an upfront payment of $60 million and MacroGenics will be eligible to receive up to $1.7 billion in target nomination, option fees and development regulatory and commercial milestones. MacroGenics will also be eligible to receive tiered double-digit royalties on worldwide net sales of MGDO24, and a flat royalty on worldwide net sales of products resulting from the 2 additional research programs. MacroGenics will be responsible for the ongoing Phase I study of MGD024, and Gilead may elect to exercise his option to license the program at predefined decision points. The Phase I study will include a dose escalation segment and an expansion segment that has been intended to evaluate MGD024 as monotherapy and in combination with other therapies across multiple indications. Next, I will provide an update on our product candidates being developed by our collaboration partners for which we retain certain economic rights. As Jim mentioned earlier, we and Provention await the FDA's decision on teplizumab, an anti-CD3 monoclonal antibody that Provention acquired from us under an asset purchase agreement in 2018. Provention is developing teplizumab for both the treatment and prevention of Type 1 diabetes. The extended PDUFA target action date for the prevention of Type 1 diabetes indication is November 17, 2022. MacroGenics is eligible to receive royalties on net sales of teplizumab, if approved, in addition to milestone payments that totaled $170 million, inclusive of the $60 million U.S. approval milestone. Retifanlimab is an investigational anti-PD-1 mAb that we exclusively licensed to Incyte Corporation. MacroGenics is eligible to receive royalties on net sales of retifanlimab, if approved, in addition to milestone payments. In July 2022, MacroGenics received $30 million in milestone payments from Incyte as part of its collaboration agreement. Retifanlimab is currently being studied as monotherapy or in combination with other agents across multiple studies. Finally, as a reminder, we previously announced in August our restructuring plan, which included the prioritization of our pipeline of product candidates, a 15% workforce reduction and plant closure of 2 facilities with the goal of delivering value-creating data with our existing and anticipated financial resources. All of these cost saving measures are proceeding according to plan. With our continued progress through 2022, we remain committed to developing and delivering life-changing medicines to cancer patients. We would be now happy to open the call for questions. Operator?
