CD123 x CD3

Molecular Partners is changing the protocol in an early-phase to allow higher and more frequent dosing. Molecular Partners has identified “suboptimal exposure” to its tetra-specific T-cell engager as the potential cause of the limited response rate in its early-phase trial, prompting the Swiss biotech to change the protocol to try to dial up the impact of the compound.The candidate, MP0533, features six binding domains. Three of the domains engage CD33, CD123 and CD70 on the target tumor cells. One domain targets CD3 to engage T cells, and the final two domains are there to prolong the half-life of the candidate in circulation. Molecular Partners picked the tumor targets to kill cancer cells that express two or more antigens while sparing healthy, single-expressing cells. Investigators are testing the candidate in a phase 1/2a study that is enrolling patients with relapsed or refractory acute myeloid leukemia and myelodysplastic syndrome. As of July 29, the biotech had seen four clinical responses in the 28 patients treated in the first six dose cohorts.Philippe Legenne, M.D., fresh from his appointment as Molecular Partners’ permanent chief medical officer, walked through the interim data on an earnings call Tuesday. After discussing the number of responses, Legenne concluded that the company “need[s] to have more than that to be completely satisfied and to qualify that we would unlock the potential of that compound.” Molecular Partners has identified “suboptimal exposure” as a barrier to realizing the full potential of the candidate. That observation led the biotech to prepare to change the protocol to allow higher and more frequent dosing in pursuit of improved response rate, depth of response and durability. Investigators are now enrolling patients in the eighth dose cohort and could go up to the eleventh dose level.“What we hope is that we are going to ... reduce the tumor ... burden. We see that we have more responses in the lower tumor burden than in the higher,” Legenne said. “We also want to avoid by design having chronic exposure, because we are also conscious of that concept of T-cell exhaustion. So we wouldn't want to be continuous all the time. Then the question is how little is enough.”One outstanding question is whether increasing the dose will improve the responses. Molecular Partners saw one complete response on the fourth dose and one case of morphologic leukemia-free state at the third, fifth and sixth doses. The biotech is still collecting data on the seventh dose, but, at this stage, there is no clear dose response. 

Upcoming poster presentation of protocol-defined TAMARACK Phase 2 mCRPC study data at ESMO in SeptemberReceived $100.0 million in milestones related to Incyte’s advancement of ZYNYZ® (retifanlimab-dlwr) subsequent to quarter-endConfirming cash runway guidance into 2026 ROCKVILLE, Md., Aug. 06, 2024 (GLOBE NEWSWIRE) -- MacroGenics, Inc. (NASDAQ: MGNX), a biopharmaceutical company focused on discovering, developing, manufacturing and commercializing innovative antibody-based therapeutics for the treatment of cancer, today provided an update on its recent corporate progress and reported financial results for the quarter ended June 30, 2024. “We are pleased to have the opportunity to present updated safety and efficacy data from our Phase 2 TAMARACK trial of vobra duo at the upcoming European Society for Medical Oncology (ESMO) Congress in September," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “In addition, we recently solidified our cash position with the receipt of $100.0 million in milestones, following the positive Phase 3 top-line results from Incyte’s registrational studies of retifanlimab in both anal and lung cancer.” Updates on Proprietary Investigational Programs Recent progress and anticipated events related to MacroGenics’ investigational product candidates are highlighted below. B7-H3-Directed Therapies Vobramitamab duocarmazine (vobra duo) is an antibody-drug conjugate (ADC) that targets B7-H3, an antigen with broad expression across multiple solid tumors and a member of the B7 family of molecules involved in immune regulation. The TAMARACK Phase 2 study of vobra duo is being conducted in patients with metastatic castration-resistant prostate cancer (mCRPC) who were previously treated with one prior androgen receptor axis-targeted therapy (ARAT). Participants may have received up to one prior taxane-containing regimen, but no other chemotherapy agents. The TAMARACK study is designed to evaluate vobra duo at two different doses: 2.0 mg/kg or 2.7 mg/kg every four weeks (q4W). MacroGenics completed enrollment of the TAMARACK study in the fourth quarter of 2023, and the study has reached its landmark primary endpoint of 6-month radiographic progression-free survival (rPFS) rate. While mCRPC study participants are no longer being dosed in the study, participants continue to be monitored for adverse events, disease progression and survival.Updated TAMARACK safety and efficacy data, including the study’s primary endpoint, will be presented in a poster session at the ESMO Congress in September 2024. This data will be based on a data cut-off date of July 9, 2024. The abstract submitted to ESMO in May was based on an April 12 data cut off. MacroGenics expects to have the mature efficacy findings, including median rPFS, in the second half of 2024 and plans to present the data at a subsequent medical conference.Following the ESMO poster presentation, the Company plans to host a conference call with investors to discuss the TAMARACK data and potential next steps for vobra duo.MacroGenics continues to enroll a Phase 1/2 dose escalation study of vobra duo in combination with lorigerlimab in patients with various advanced solid tumors. The Company anticipates commencing a dose expansion study of this combination later this year. MGC026 is a clinical B7-H3-targeting ADC that is site-specifically conjugated to exatecan, a topoisomerase I inhibitor payload developed by Synaffix (a Lonza company). With distinct mechanisms of action, vobra duo and MGC026 may address different cancers, tumor stages, or be used in combination with alternate agents — or potentially with one another — to enhance their clinical utility. A Phase 1 dose escalation study of MGC026 in patients with advanced solid tumors is ongoing. Lorigerlimab Lorigerlimab is a bispecific, tetravalent PD-1 × CTLA-4 DART® molecule. In addition to the ongoing study of lorigerlimab in combination with vobra duo mentioned above, MacroGenics is enrolling LORIKEET, a randomized Phase 2 study of lorigerlimab in combination with docetaxel vs. docetaxel alone in second-line, chemotherapy-naïve mCRPC patients. A total of 150 patients are planned to be treated in the 2:1 randomized study. The current trial design includes a primary study endpoint of rPFS. The Company anticipates completing enrollment of the study in 2024 or early 2025 and providing a clinical update in the first half of 2025. Emerging ADC Pipeline MGC028 is a preclinical ADC incorporating an ADAM9-targeting antibody and represents the second MacroGenics ADC molecule that incorporates Synaffix’s novel site-specific linker and topoisomerase I inhibitor-based cytotoxic payload. ADAM9 (a disintegrin and metalloprotease domain 9) is a member of the ADAM family of multifunctional type 1 transmembrane proteins that play a role in tumorigenesis and cancer progression and is overexpressed in multiple cancers, making it an attractive target for cancer treatment. The Company continues to anticipate submitting an investigational new drug (IND) application for MGC028 by the end of 2024 and initiating a Phase 1 clinical study in 2025. Partnered Programs MGD024 is a next-generation, humanized CD123 × CD3 DART molecule designed to minimize cytokine-release syndrome, while maintaining anti-tumor cytolytic activity, and permitting intermittent dosing. MacroGenics continues to enroll patients in a Phase 1 dose-escalation study of MGD024 in patients with CD123-positive neoplasms, including acute myeloid leukemia and myelodysplastic syndromes. Under an October 2022 exclusive option and collaboration agreement, Gilead Sciences, Inc. (Gilead) has the option to license MGD024 at predefined decision points during the Phase 1 study.ZYNYZ® (retifanlimab-dlwr) is a humanized monoclonal antibody targeting PD-1 that the Company licensed to Incyte Corporation (Incyte) in 2017. Incyte recently announced positive Phase 3 top-line results for its registrational studies of retifanlimab in squamous cell carcinoma of the anal canal and non-small cell lung cancer and continues to conduct global studies of retifanlimab across multiple indications.Subsequent to June 30, 2024, MacroGenics announced the achievement of $100.0 million in milestones from Incyte related to development progress of retifanlimab, following an agreement on July 24, 2024, pursuant to which certain milestones were deemed to have been met. MacroGenics is further eligible to receive up to a total of $210.0 million in remaining development and regulatory milestones and up to $330.0 million in potential commercial milestones from Incyte. MacroGenics receives tiered royalties of 15% to 24% from Incyte on any global net sales of the product and manufactures a portion of Incyte’s global commercial supply of retifanlimab. Second Quarter 2024 Financial Results Cash Position: Cash, cash equivalents and marketable securities balance as of June 30, 2024, was $140.4 million, compared to $229.8 million as of December 31, 2023. The June 30, 2024 balance did not include the $100.0 million in milestones subsequently received from Incyte.Revenue: Total revenue was $10.8 million for the quarter ended June 30, 2024, compared to total revenue of $13.1 million for the quarter ended June 30, 2023. The decrease was primarily due to less revenue recognized under the Provention Asset Purchase Agreement and was partially offset by increased revenue from the Company’s collaboration with Gilead and increased contract manufacturing revenue.R&D Expenses: Research and development expenses were $51.7 million for the quarter ended June 30, 2024, compared to $43.2 million for the quarter ended June 30, 2023. The increase was primarily due to manufacturing and IND-enabling costs related to MGC028.SG&A Expenses: Selling, general and administrative expenses were $14.4 million for the quarter ended June 30, 2024, compared to $13.7 million for the quarter ended June 30, 2023.Net Income (Loss): Net loss was $55.7 million for the quarter ended June 30, 2024, compared to net income of $57.5 million for the quarter ended June 30, 2023. Net income for the quarter ended June 30, 2023 included approximately $100.0 million as a component of Other Income related to the sale of the Company’s single-digit royalty interest on global net sales of TZIELD® (teplizumab-mzwv) to DRI Healthcare Acquisitions LP in March 2023.Shares Outstanding: Shares of common stock outstanding as of June 30, 2024 were 62,720,969.Cash Runway Guidance: MacroGenics anticipates that its cash, cash equivalents and marketable securities balance of $140.4 million as of June 30, 2024, plus the $100.0 million in milestones subsequently received from Incyte, in addition to projected and anticipated future payments from partners and product revenues should support its cash runway into 2026. The Company’s expected funding requirements reflect anticipated expenditures related to the Phase 2 TAMARACK clinical trial, the Phase 2 LORIKEET study as well as MacroGenics’ other ongoing clinical and preclinical studies. No Conference Call Given the embargoed TAMARACK data being presented at the upcoming ESMO presentation, the Company’s management has entered a quiet period and will not be hosting a conference call to discuss its financial results or corporate progress for the quarter ended June 30, 2024. The Company intends to resume its quarterly results conference calls in the future.

ROCKVILLE, Md., Feb. 24, 2022 (GLOBE NEWSWIRE) -- MacroGenics, Inc. (NASDAQ: MGNX), a biopharmaceutical company focused on developing and commercializing innovative antibody-based therapeutics for the treatment of cancer, today provided an update on its recent corporate progress and reported financial results for the year ended December 31, 2021. “We are excited about our 2022 plans for our B7-H3-directed programs for the potential treatment of multiple solid tumors. We believe we are well-positioned to be a leader in this promising field and are prioritizing our efforts around B7-H3. First, I am pleased to share that later this quarter, we plan to meet with the U.S. Food and Drug Administration (FDA) to discuss the design of a potential registration-directed study of MGC018 in patients with metastatic castration-resistant prostate cancer (mCRPC). Second, we expect to initiate a study of MGC018 in combination with lorigerlimab, our bispecific DART molecule targeting PD-1 and CTLA-4, in the coming weeks. And third, during the second half of this year, we intend to provide an update from a study of our second B7-H3 targeted molecule, enoblituzumab, being evaluated in combination with two of our checkpoint molecules in front-line squamous cell carcinoma of the head and neck (SCCHN). Beyond these B7-H3 programs, we are advancing several of our other clinical-stage molecules and have a variety of ongoing preclinical activities intended to expand our pipeline of differentiated investigational product candidates for the potential treatment of cancer,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. Updates on Proprietary Programs B7-H3 Programs: MacroGenics is developing two investigational, clinical product candidates that target B7-H3, an antigen with broad expression across multiple solid tumor types and a member of the B7 family of molecules involved in immune regulation. Recent highlights for these two molecules include: MGC018is an antibody-drug conjugate (ADC) that targets B7-H3. MacroGenics presented encouraging preliminary clinical results from an ongoing Phase 1/2 study of MGC018 in patients with solid tumors at the American Society of Clinical Oncology (ASCO) and European Society for Medical Oncology (ESMO) meetings in 2021. The Phase 1/2 study expansion cohorts are fully enrolled for patients with mCRPC (n=40) and smaller cohorts of patients (n=approximately 20 each) with non-small cell lung cancer (NSCLC), melanoma and triple negative breast cancer (TNBC), while the Company continues to recruit patients for the SCCHN cohort. MacroGenics plans to meet with FDA later this quarter to discuss its development strategy in mCRPC. In addition, the Company intends to provide an update on clinical data from the dose expansion cohorts in the second half of 2022 as the data further mature. Finally, beyond monotherapy, the Company expects to initiate a combination study of MGC018 with lorigerlimab across multiple indications in the coming weeks. Enoblituzumab is an Fc‐engineered, monoclonal antibody (mAb) that targets B7‐H3. MacroGenics continues to recruit patients into its Phase 2 study of enoblituzumab in combination with retifanlimab, the Company's investigational, anti-PD-1 antibody that was licensed to Incyte, in front-line patients with SCCHN who are PD-L1 positive and with tebotelimab in SCCHN patients who are PD-L1 negative. The Company expects to complete enrollment of the PD-L1 positive patient cohort during the first half of this year and provide an update on this cohort during the second half of the year. I-Mab, MacroGenics’ partner in Greater China, announced in December that the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration (NMPA) approved its Investigational New Drug (IND) submission for the initiation of a Phase 2 trial in China for enoblituzumab in combination with pembrolizumab in patients with solid tumors, including NSCLC, urothelial carcinoma and other selected cancers. DART Molecules for Immune Checkpoint Blockade: MacroGenics is studying multiple investigational, PD-1-directed programs to provide further differentiation from existing PD-1-based treatment options and enable combination opportunities across the Company’s portfolio. Recent highlights include: Lorigerlimab (formerly MGD019)is a bispecific, tetravalent DART molecule targeting PD-1 and CTLA-4. MacroGenics is conducting a Phase 1/2 dose expansion study in cohorts of patients with microsatellite stable colorectal cancer (MSS CRC), mCRPC, melanoma and checkpoint-naïve NSCLC. The Company anticipates sharing data from this ongoing study in the second half of 2022. As described above, MacroGenics expects to initiate a dose escalation study of MGC018 in combination with lorigerlimab in the coming weeks. Tebotelimab is a bispecific, tetravalent DART molecule targeting PD-1 and LAG-3. Tebotelimab was evaluated in a Phase 1/2 dose expansion study in several tumor types and is currently being studied in combination with enoblituzumab in SCCHN. The Company expects to provide an update on potential future development plans for tebotelimab in the second half of 2022. MacroGenics' partner in Greater China, Zai Lab, recently informed the Company that it has decided to discontinue development of tebotelimab for indications it was enrolling in its territory and is evaluating future development plans in other indications. Bispecific CD123 × CD3 DART molecule: MacroGenics has prioritized the development of MGD024, its investigational, next-generation CD123 × CD3 DART molecule, and will discontinue the development of flotetuzumab. Recent updates of these DART molecules include: MGD024is a next-generation, humanized CD123 × CD3 DART molecule designed to minimize cytokine-release syndrome, while maintaining anti-tumor cytolytic activity, and permitting intermittent dosing through a longer half-life. In November, MacroGenics announced submission of an IND application for MGD024 to FDA. At the American Society of Hematology (ASH) Annual Meeting in December, MacroGenics presented preclinical data from the combination of MGD024 with standard-of-care agents used to treat CD123-positive hematological malignancies. The Company expects to initiate a Phase 1 dose escalation study of MGD024 in patients with CD123-positive neoplasms, including acute myeloid leukemia (AML), pending IND clearance by FDA. Flotetuzumab is the Company’s first-generation, investigational, bispecific CD123 × CD3 DART molecule. An interim efficacy threshold from the single-arm study evaluating flotetuzumab in patients who were refractory to induction therapy was met with manageable safety. However, the Company has recently decided to prioritize the development of MGD024 and discontinue development of flotetuzumab, in view of the Company’s belief that MGD024 may offer certain advantages over flotetuzumab, including easier dose administration and a more facile means to combine with other agents. Margetuximab is an Fc-engineered mAb that targets the HER2 oncoprotein, which is expressed by certain breast, gastroesophageal and other solid tumor cells. MARGENZA® (margetuximab-cmkb) was launched in March 2021 by MacroGenics and its commercial partner, Eversana Life Science Services, LLC, for the treatment of adult patients with metastatic HER2-positive breast cancer, in combination with chemotherapy, who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease. In January 2022, Zai Lab announced that the China NMPA accepted the New Drug Application (NDA) for margetuximab for the treatment of the same HER2-positive breast cancer indication. Zai Lab recently informed MacroGenics that they have decided to discontinue enrollment of Module B of the MAHOGANY study in gastric cancer based on their review of both the clinical data and the changing treatment landscape. MacroGenics previously announced in November 2021 that the Company had decided to discontinue enrollment of Module A of the MAHOGANY study. Selected Partnered Program Updates: IMGC936is an investigational ADC that targets ADAM9, a cell surface protein over-expressed in several solid tumor types, and is being developed jointly under a 50/50 collaboration with ImmunoGen, Inc. Under the collaboration, ImmunoGen is leading clinical development of IMGC936 in a Phase 1 clinical trial evaluating safety and pharmacokinetics in multiple solid tumors and has indicated they anticipate disclosing initial data in 2022. Teplizumab is an investigational, anti-CD3 monoclonal antibody acquired from MacroGenics by Provention Bio, Inc. under an asset purchase agreement in 2018 for which MacroGenics is entitled to receive future milestone payments and royalties on net sales. Provention is developing teplizumab for the treatment of type 1 diabetes (T1D). On February 22, 2022, Provention announced that it had resubmitted the Biologics License Application (BLA) for teplizumab for the delay of clinical T1D in at-risk individuals. The BLA resubmission followed Provention’s Type B meeting with FDA earlier in the year. 2021 Financial Results Cash Position: Cash, cash equivalents and marketable securities as of December 31, 2021, were $243.6 million, compared to $272.5 million as of December 31, 2020. Revenue: Total revenue, consisting primarily of revenue from collaborative agreements, was $77.4 million for the year ended December 31, 2021, compared to total revenue of $104.9 million for the year ended December 31, 2020.
