Recent Corporate Highlights:
General Corporate:
- In
July 2023 , Mustang announced that the Company amended its previously announced asset purchase agreement with uBriGene, theU.S. subsidiary of uBriGene Group, a leading cell and gene therapy contract development and manufacturing organization, and closed the transaction. Per the terms of the amended asset purchase agreement, at closing, uBriGene acquired all of Mustang’s assets primarily relating to the manufacturing and production of cell and gene therapies at Mustang’s state-of-the-art clinical- and commercial-scale cell and gene therapy manufacturing facility inWorcester, Massachusetts , for upfront consideration of$6 million in cash. Mustang’s lease to the premises on which the facility is located (as well as related contracts and manufacturing personnel) did not transfer at closing because such transfer requires the consent of the landlord, which has requested an additional thirty business days to consider the proposed transfer following the landlord’s receipt of the final determination letter of theU.S. Committee on Foreign Investment inthe United States (“CFIUS”) regarding the transaction (as discussed further below) and a summary of Mustang’s and uBriGene’s reaction to such final determination. An additional$5 million contingent payment will be payable to Mustang upon (i) Mustang’s raising$10 million in gross proceeds from equity raises following the closing of the transaction and (ii) completion of the assignment of Mustang’s lease to uBriGene, which remains subject to landlord’s approval, within two years of the closing. Until the lease is transferred to uBriGene, Mustang will retain its facility lease and facility personnel, and will continue to occupy the leasehold premises and manufacture its lead product candidate, MB-106, at that site.
As previously disclosed, in connection with the sale of its manufacturing facility to uBriGene, Mustang and uBriGene previously submitted a voluntary notice with CFIUS to obtain clearance for the transaction, although obtaining such clearance was not a condition to closing the transaction. OnNovember 13, 2023 , CFIUS requested Mustang and uBriGene withdraw and re-file their joint voluntary notice to allow more time for review and discussion regarding the nature and extent of national security risk posed by the Transaction, and whether and to what extent mitigation of risk would be feasible. Upon CFIUS’s request, Mustang and uBriGene submitted a request to withdraw and re-file their joint voluntary notice. OnNovember 13, 2023 , CFIUS granted this request, accepted the joint voluntary notice and commenced a new 45-day review period commencing onNovember 14, 2023 , which may be followed by a 45-day investigation period. Mustang and uBriGene have been and will continue to be actively engaged with CFIUS, and they remain fully committed to obtaining clearance from CFIUS and completing the full transfer of the manufacturing facility to uBriGene. There can be no assurance, however, that CFIUS will ultimately provide clearance with respect to the transaction, or what mitigating measures may be required in order to obtain such clearance. - In
October 2023 , Mustang completed a registered direct offering priced at-the-market for approximately$4.4 million in gross proceeds.
MB-106:
- Mustang’s lead clinical candidate is MB-106, a CD20-targeted, autologous CAR-T cell therapy to treat a wide range of hematologic malignancies, including WM and FL. MB-106 continues to demonstrate a favorable safety and efficacy profile in both the Fred Hutch single institution and
Mustang Bio multicenter Phase 1/2 clinical trials. - In
August 2023 ,Mustang Bio announced the first data from its ongoing multicenter, open-label, non-randomized Phase 1/2 clinical trial evaluating the safety and efficacy of MB-106 CAR-T cell therapy. Initial data show substantial clinical benefit in four of four indolent lymphoma patients, including two complete responses in FL patients, one who was previously treated with CD19 CAR-T cell therapy. From a safety perspective, 3 patients experienced Grade 1 cytokine release syndrome and no occurrences of immune effector cell-associated neurotoxicity syndrome were reported. These data align with ongoing results from the investigator-sponsored trial at Fred Hutch that show ongoing complete remission for more than three years. - The FDA granted Orphan Drug Designation to MB-106 for the treatment of WM, and results from this arm of the multicenter trial are expected to support an accelerated Phase 2 registration strategy for WM, with the first pivotal Phase 2 patient with WM to be treated potentially in mid-2024.
Mustang Bio will report additional safety and efficacy data from the multicenter trial at the 65th ASH Annual Meeting, taking placeDecember 9-12, 2023 , inSan Diego . Finally,Mustang Bio expects to initiate a pivotal Phase 2 clinical trial in at least one additional B-cell malignancy in 2025. Mazyar Shadman , M.D., M.P.H., Study Chair, Associate Professor and physician at Fred Hutch andUniversity of Washington also presented data from the ongoing Fred Hutch Phase 1/2 clinical trial, specific to two B-cell non-Hodgkin lymphoma cohorts, FL and WM. In the FL data cohort (n=20), an overall response rate (“ORR”) of 95% was seen, of which 80% of patients experienced a complete response and 15% had a partial response. The complete response patients include a patient who was previously treated with a CD19-directed CAR-T cell therapy. Of the six patients who experienced cytokine release syndrome (“CRS”), only one had Grade 2, while the remaining five had Grade 1. Ten patients continue to experience complete response for more than 10 months, four patients have experienced complete response for more than two years (all ongoing), and the first patient enrolled has sustained complete response for more than 3 years. In the WM cohort (n=6), all of whom had received prior Bruton tyrosine kinase inhibitor, two patients experienced complete response, one of whom continues to be in complete response at more than 22 months. No patients experienced CRS or immune effector cell-associated neurotoxicity syndrome over Grade 2. None of the six patients with WM have needed to start new therapy for their disease.
MB-109:
- In
October 2023 ,Mustang Bio announced that the FDA accepted the Company’s IND to initiate a Phase 1 open label, multicenter clinical trial to assess the safety, tolerability and efficacy of MB-109, a novel combination of MB-101 (IL13Rα2‐targeted CAR-T cell therapy) and MB-108 (HSV-1 oncolytic virus), for the treatment of recurrent GBM and high-grade astrocytoma. - As previously reported, preclinical data presented at the
American Association for Cancer Research (“AACR”) Annual Meeting 2022 supported this combination therapy to optimize results to treat recurrent GBM. The combination leverages MB-108 to make cold tumors “hot,” thereby potentially improving the efficacy of MB-101 CAR-T cell therapy. Data presented separately on MB-101 and MB-108 showed infusions were well tolerated in recurrent GBM patients. Two patients treated solely with MB-101 who had high levels of intratumoral CD3+ T cells pre-therapy (i.e., “hot” tumors) achieved complete responses lasting 7.5 and 31+ months, respectively. Importantly, of the 53 City of Hope (“COH”) Phase 1 patients disclosed at AACR meeting in 2022, these two complete responses were observed in the two patients with the “hottest” tumors prior to treatment with MB-101.
