SUMMARY OF RISK FACTORS
Our business is subject to risks of which you should be aware before making an investment decision. The risks described below are a summary of the principal risks associated with an investment in us and are not the only risks we face. You should carefully consider these risk factors, the risk factors described in Item 1A, and the other reports and documents that we have filed with the Securities and Exchange Commission (“SEC”).
Risks Related to our Finances and Capital Requirements
● | We have incurred significant losses since our inception and anticipate that we will incur continued losses for the foreseeable future. We have not generated any revenue from our development stage products, and we do not know when, or if, we will generate any revenue. |
● | Our short operating history makes it difficult to evaluate our business and prospects. |
● | Our success is contingent upon raising additional capital, which efforts may fail. Even if successful, our future capital raising activities may dilute our current stockholders, restrict our operations, cause us to relinquish proprietary rights. |
Risks Pertaining to our Business Strategy, Structure and Organization
● | Our future growth and success depend on our ability to successfully develop and commercialize our product candidates, which we have yet to do. |
● | Our growth and success depend on our acquiring or in-licensing products or product candidates and integrating such products into our business, and we may have limited growth opportunities if we fail to do so. |
● | Our future success is highly dependent on the successful development of our CAR T technology and product candidates. |
Risks Inherent in Drug Development and Commercialization
● | Preclinical development is highly speculative and carries a high failure risk. |
● | We may not receive the required regulatory approvals for any of our product candidates on our projected timelines, if at all, which may result in increased costs and delay our ability to generate revenue. |
● | We may not obtain the desired labeling claims or intended uses for product promotion, or favorable scheduling classifications, to successfully promote our products. |
● | If a product candidate demonstrates adverse side effects, we may need to abandon or limit the development of such product candidate. |
● | Even if a product candidate is approved, it may be subject to various post-marketing requirements, including studies or clinical trials, and increased regulatory scrutiny. |
● | Our competitors may develop treatments for our or our partner companies’ products’ target indications, which could limit our product candidates’ commercial opportunity and profitability. |
● | If our products are not broadly accepted by the healthcare community, the revenues from any such product will likely be limited. |
● | Any successful products liability claim related to any of our current or future product candidates may cause us to incur substantial liability and limit the commercialization of such products. |
● | Our gene therapy product candidates are based on a novel technology, which makes it difficult to predict the time and cost of product candidate development and subsequently obtaining regulatory approval. |
Risks Related to Reliance on Third Parties
● | We rely, and expect to continue to rely, on third parties to conduct our preclinical studies and clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such trials or complying with applicable regulatory requirements. |
3
● | We contract with third parties for the manufacture of our product candidates for preclinical and clinical testing and may also do so for commercialization, if and when our product candidates are approved. |
● | We rely on clinical data and results obtained by third parties, which may prove inaccurate or unreliable. |
● | We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms. |
Risks Relating to Legislation and Regulation Affecting the Biopharmaceutical and Other Industries
● | We operate in a heavily regulated industry, and we cannot predict the impact that any future legislation or administrative or executive action may have on our operations. |
● | We may be subject to anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings. |
● | We are subject to numerous environmental, health and safety laws and regulations and could become subject to fines or penalties or incur costs that could harm our business |
Risks Pertaining to Intellectual Property and Potential Disputes with Licensors Thereof
● | If we are unable to maintain sufficient patent protection for our technology and products, our competitors could develop and commercialize products similar or identical to ours and our ability to successfully commercialize our technology and products could be impaired. |
● | We depend on our licensors for the maintenance and enforcement of to maintain and enforce the intellectual property covering certain of our product candidates. |
● | We or our licensors may be subject to costly and time-consuming litigation for infringement of third-party intellectual property rights or to enforce our or our licensors’ patents. |
● | Any dispute with our licensors may affect our ability to develop or commercialize our product candidates. |
Risks Relating to Our Control by Fortress Biotech, Inc. (“Fortress”)
● | Fortress controls a voting majority of our common stock and has the right to receive significant share grants annually, which will result in dilution of our other stockholders and could reduce the value of our common stock. |
● | We have entered into certain agreements with Fortress and may have received better terms from unaffiliated third parties. |
Risks Related to Conflicts of Interest
● | We share certain directors with Fortress, which could create conflicts of interest between us and Fortress. |

Note 1 - Organization, Description of Business and Liquidity and Capital Resources
Mustang Bio, Inc. (the “Company” or “Mustang”) was incorporated in Delaware on March 13, 2015. Mustang is as a clinical-stage biopharmaceutical company focused on translating today’s medical breakthroughs in cell and gene therapy into potential cures for hematologic cancers, solid tumors and rare genetic diseases. The Company may acquire rights to these technologies by licensing the rights or otherwise acquiring an ownership interest in the technologies, funding their research and development and eventually either out-licensing or bringing the technologies to market.
The Company is a majority-controlled subsidiary of Fortress Biotech, Inc. (“Fortress” or “Parent”).
The Company's common stock is listed on the NASDAQ Global Market and trades under the symbol “MBIO”.
Liquidity and Capital Resources
The Company has incurred substantial operating losses and expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. As of March 31, 2021, the Company had an accumulated deficit of $
The Company has funded its operations to date primarily through the sale of equity. The Company expects to continue to use the proceeds from previous financing transactions primarily for general corporate purposes, including financing the Company’s growth, developing new or existing product candidates, and funding capital expenditures, acquisitions and investments. The Company currently anticipates that its cash and cash equivalents balances at March 31, 2021, are sufficient to fund its anticipated operating cash requirements for at least one year from the filing date of this Form 10-Q.
The Company will be required to expend significant funds in order to advance the development of its product candidates. The Company will require additional financings through equity and debt offerings, collaborations and licensing arrangements or other sources to fully develop, prepare regulatory filings, obtain regulatory approvals and commercialize its existing and any new product candidates. In addition to the foregoing, based on the Company’s current assessment, the Company does not expect any material impact on its long-term development timeline and its liquidity due to the worldwide spread of the COVID-19 virus. However, the Company is continuing to assess the effect on its operations by monitoring the spread of COVID-19 and the actions implemented to combat the virus throughout the world.
Note 2 - Significant Accounting Policies
Basis of Presentation
The accompanying unaudited interim condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the Exchange Act. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the unaudited interim condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. They may not include all of the information and footnotes required by GAAP for complete financial statements. Therefore, these financial statements should be read in conjunction with the Company's audited financial statements and notes thereto for the year ended December 31, 2020, which were included in the Company’s Form 10-K and filed with the SEC on March 24, 2021. The results of operations for any interim periods are not necessarily indicative of the results that may be expected for the entire fiscal year or any other interim period.
Use of Estimates
The Company’s unaudited condensed financial statements include certain amounts that are based on management’s best estimates and judgments. The Company’s significant estimates include, but are not limited to, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Due to the uncertainty inherent in such estimates actual results could differ from those estimates.

Significant Accounting Policies
There have been no material changes to the Company’s significant accounting policies previously disclosed in the Company’s Form 10-K filed with the SEC on March 24, 2021.
Recently Issued Accounting Standards
In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, “Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption will be permitted. The Company is currently evaluating the impact of this standard on its financial statements.
In June 2016, FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 requires that expected credit losses relating to financial assets are measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. Recently, the FASB issued the final ASU to delay adoption for smaller reporting companies to calendar year 2023. The Company is currently assessing the impact of the adoption of this ASU on its financial statements.

Note 9 – Net Loss per Share
Net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period less unvested restricted stock. Since dividends are declared, paid and set aside among the holders of shares of common stock and Class A common shares pro-rata on an as-if-converted basis, the two-class method of computing net loss per share is not required. Diluted net loss per share does not reflect the effect of shares of common stock to be issued upon the exercise of options and warrants, outstanding Class A preferred shares, and unvested restricted stock and restricted stock units as their inclusion would be anti-dilutive.

Overview
Mustang Bio, Inc. (“Mustang,” “We,” “Us” or the “Company”) is a clinical-stage biopharmaceutical company focused on translating today’s medical breakthroughs in cell and gene therapies into potential cures for hematologic cancers, solid tumors and rare genetic diseases. We aim to acquire rights to these technologies by licensing or otherwise acquiring an ownership interest in the technologies, funding their research and development and eventually either out-licensing or bringing the technologies to market.
Our pipeline is currently focused in three core areas: gene therapy programs for rare genetic disorders, chimeric antigen receptor (“CAR”) engineered T cell (“CAR T”) therapies for hematologic malignancies and CAR T therapies for solid tumors. For each therapy we have partnered with world class research institutions. For our gene therapy program, we have partnered with St. Jude Children’s Research Hospital (“St. Jude”) in the development of a first-in-class ex vivo lentiviral treatment of X-linked severe combined immunodeficiency (“XSCID”), and for our CAR T therapies we have partnered with the City of Hope National Medical Center (“COH”), Fred Hutchinson Cancer Research Center (“Fred Hutch”) and Nationwide Children’s Hospital (“Nationwide”).
Gene Therapy
In partnership with St. Jude and the National Institutes of Health (“NIH”), our gene therapy program is being conducted under an exclusive license to develop a potentially curative treatment for XSCID, a rare genetic immune system condition also known as bubble boy disease in which affected patients do not live beyond infancy without treatment. This first-in-class ex vivo lentiviral gene therapy is currently in two Phase 1/2 clinical trials involving two different autologous cell products: a multicenter trial of the MB-107 product in newly diagnosed infants sponsored by St. Jude and a single-center trial of the MB-207 product in previously transplanted patients sponsored by the NIH.
18
In May 2020, we submitted an Investigational New Drug (“IND”) application with the U.S. Food and Drug Administration (“FDA”) to initiate a registrational multicenter Phase 2 clinical trial of MB-107 in newly diagnosed infants with XSCID who are under the age of two. In response, the FDA identified Chemistry, Manufacturing, and Control (“CMC”) hold issues that the Company satisfactorily addressed in a December 2020 submission to the FDA, and the CMC hold was removed in January 2021. The trial is expected to enroll 10 patients who, together with 15 patients enrolled in the current multicenter trial led by St. Jude, will be compared with 25 matched historical control patients who have undergone hematopoietic stem cell transplant (“HSCT”). The primary efficacy endpoint will be event-free survival, and we are targeting topline data from the trial in the second half of 2022.
We further expect to file an IND in the second quarter of 2021 for a registrational multicenter Phase 2 clinical trial of lentiviral gene therapy in previously transplanted XSCID patients (MB-207). We anticipate enrolling 20 patients, and we are targeting topline data for this trial in the first half of 2023.
CAR T Therapies
Our pipeline of CAR T therapies is being developed under exclusive licenses from several world class research institutions. Our strategy is to license these therapies, support preclinical and clinical research activities by our partners and transfer the underlying manufacturing technology to our cell processing facility located in Worcester, Massachusetts, to conduct our own clinical trials.
We are developing CAR T therapies for hematologic malignancies in partnership with COH targeting CD123 (MB-102) and CS1 (MB-104) and with Fred Hutch targeting CD20 (MB-106). Phase 1 clinical trials sponsored by COH for MB-102 and MB-104 and by Fred Hutch for MB-106 are underway. In the third quarter of 2019 the FDA approved our IND application to initiate a multicenter Phase 1/2 clinical trial of MB-102, and our clinical trial has begun enrollment for the treatment of patients with blastic plasmacytoid dendritic cell neoplasm (“BPDCN”). On May 10, 2021, the FDA approved our IND application to initiate a multicenter Phase 1/2 clinical trial of MB-106 for the treatment of patients with non-Hodgkin lymphoma and chronic lymphocytic leukemia, and in the third quarter of 2021 we expect to enroll the first patient in this trial. We plan to file an IND application for a multicenter Phase 1/2 trial for MB-104 for the treatment of patients with multiple myeloma once COH has established a safe and effective dose.
We are also developing CAR T therapies for solid tumors in partnership with COH targeting IL13Ra2 (MB-101), HER2 (MB-103) and prostate stem cell antigen (“PSCA”) (MB-105). In addition, we have partnered with Nationwide for the C134 oncolytic virus (MB-108) in order to enhance the activity of MB-101 for the treatment of patients with glioblastoma multiforme (GBM). Phase 1 clinical trials sponsored by COH for MB-101, MB-103 and MB-105 are underway. A Phase 1 clinical trial sponsored by the University of Alabama at Birmingham (“UAB”) for MB-108 began during the third quarter of 2019 and, in the fourth quarter of 2021, we plan to file an IND application for the combination of MB-101 and MB-108 for the treatment of patients with GBM. In the third quarter of 2019, we announced that COH had started enrolling patients on a Phase 1 clinical trial of MB-101 in combination with nivolumab (commercial name: Opdivo®) and ipilimumab (commercial name: Yervoy®) in patients with recurrent malignant glioma. In the fourth quarter of 2020 we announced that COH had initiated a Phase 1, two-arm clinical trial of MB-101 in patients with leptomeningeal brain tumors (e.g., glioblastoma, ependymoma or medulloblastoma). We also plan to file IND applications and initiate our own clinical trials for MB-103 for the treatment of patients with metastatic breast cancer to brain and for MB-105 for the treatment of patients with prostate and pancreatic cancer.
Recent Events
MB-106 (CD20 CAR T for Non-Hodgkin Lymphoma and Chronic Lymphocytic Leukemia)
MB-106 targets CD20, a commercially validated target on the surface of B-cell malignancies such as non-Hodgkin lymphoma (“NHL”) and chronic lymphocytic leukemia (“CLL”) – cancers that lack a strong CAR T-based clinical focus in the U.S. MB-106 cells express a third-generation CAR derived from a fully human antibody that originated in the Fred Hutch laboratories of the late Oliver Press, M.D., Ph.D., and Brian Till, M.D., Associate Professor in the Clinical Research Division. The CAR T therapy was exclusively licensed to Mustang in 2017, and Fred Hutch and Mustang collaborated to develop the cell processing that will be used in the Mustang IND Phase 1/2 clinical trial.
19
To date, the same vector planned for use in the manufacturing of MB-106 is currently being evaluated in the ongoing Phase 1/2 study sponsored by Fred Hutch, where Mazyar Shadman, M.D., M.P.H., Associate Professor in the Clinical Research Division, is the principal investigator. Data from this ongoing study were presented by Dr. Shadman at the 62nd Annual American Society of Hematology meeting in 2020 and demonstrated a favorable safety profile in patients with NHL, with an 89% overall response rate (ORR; 8/9 patients) and a 44% complete response rate (CR; 4/9 patients).
On May 10, 2021, we announced that that the FDA has accepted the Company’s IND application to initiate a Phase 1/2 multicenter, study to assess the safety, tolerability and efficacy of MB-106.
On May 12, 2021, we announced that interim data from the ongoing Fred Hutch-sponsored Phase 1/2 clinical trial investigating the safety and efficacy of MB-106 have been selected for an e-poster presentation at the European Hematology Association 2021 Virtual Congress (“EHA2021”).
In the abstract posted on the EHA2021 website, Fred Hutch reported on 12 patients treated with MB-106, which underwent a major cell manufacturing modification after treating 7 patients with no objective responses as previously reported at the 62nd Annual American Society of Hematology meeting in 2020. The 12 patients were treated at dose levels (“DL”) ranging from 3.3x105 to 1x107 CAR T cells/kg, and clinical responses were observed at all DLs with no dose-limiting toxicities. Cytokine release syndrome occurred in 3 patients (25%): 2 patients with grade 1 and 1 patient with grade 2. Only 1 patient required tocilizumab and dexamethasone, and no immune effector cell-associated neurotoxicity syndrome of any grade was observed. Overall response rate (“ORR”) was 92% (11/12) with a complete response (“CR”) rate of 58% (7/12). In 9 patients with follicular lymphoma, ORR and CR were 89% (8/9) and 67% (6/9), respectively. The patient with CLL had a PET-negative CR and undetectable measurable residual disease in peripheral blood and bone marrow by flow cytometry (10-4) (uMRD4) on day 28. Among patients who received the highest two dose levels, DL3 (3.3x106 CAR T cells/kg; n=4) and DL4 (1x107 CAR T cells/kg; n=1), CR rate was 100% (5/5). All 7 patients who achieved a CR remain in remission at a median follow-up of 4 months. CAR T expansion was robust, with median peak blood levels of CAR+ T cells of 122 CAR+ cells/μl (range 0.27-2024), corresponding to 19% (range 0.15 - 65%) of all CD3+ cells. Updated data will be presented at EHA2021.
MB-107 (Ex vivo Lentiviral Therapy for X-linked Severe Combined Immunodeficiency (XSCID) in newborn patients)
In February 2021, we announced that the FDA removed the clinical hold on the MB-107 pivotal Phase 2 clinical trial IND application after reviewing a comprehensive CMC package that was submitted in late December 2020. The Company is proceeding with its plans to initiate the pivotal Phase 2 trial in newly diagnosed XSCID patients.
The same lentiviral vector used in MB-107 is currently being assessed in a Phase 1/2 clinical trial for XSCID in newly diagnosed infants under the age of two at St. Jude, UCSF Benioff Children’s Hospital in San Francisco and Seattle Children’s Hospital. Additionally, it is being assessed in a Phase 1/2 clinical trial at the National Institute of Allergy and Infectious Diseases (“NIAID”), part of the NIH, for XSCID patients who have been previously treated with HSCT and for whom re-treatment is indicated.
Data from the Phase 1/2 clinical trial led by St. Jude that were presented at the 61st American Society of Hematology (“ASH”) Annual Meeting in December 2019 included 11 newly diagnosed XSCID patients who had been treated with a median follow-up at data cut-off of 23.6 months (range 1.5 to 33.9 months). No serious adverse events related to treatment were reported other than hematologic ones related to low-dose busulfan conditioning. Nine patients, with a follow up of greater than 3 months, achieved normal-for-age T-cell and natural killer (NK)-cell numbers within 3-4 months post treatment. Five patients were off intravenous immunoglobulin (“IVIG”) therapy, of whom 3 responded to vaccines.
To date, all 11 patients have continued to do well and, as also announced in February 2021, 5 additional patients were enrolled at the time of the most recent analysis in early September 2020. At that time, follow-up for these 16 patients ranged from 3 months to 47 months. Similar to previous reports, the therapy continued to be well tolerated in all patients, and stable vector marking was noted in all lineages, with successful engraftment of genetically-modified T-, B-, & NK cells. All patients cleared pre-existing infections, no new severe infections were noted, and all patients were outpatients. Finally, there was no evidence of malignant transformation at a median follow up of 2 years. Enrollment will continue at all three clinical sites until Mustang initiates its multicenter pivotal Phase 2 trial of MB-107.
20
In September 2020, The Journal of Allergy and Clinical Immunology: In Practice published a case study of one patient with XSCID and disseminated Bacille Calmette-Guérin (“BCG”) infection, who was enrolled in the clinical trial at St. Jude. After 2.5 years of treatment, the patient has remained clinically well with a stable, functional immune system and protective vaccine titers, despite the complication of the disseminated BCG infection.
MB-207 (Ex vivo Lentiviral Therapy for X-linked Severe Combined Immunodeficiency (XSCID) in previously transplanted patients)
Also in February 2021, we updated results from the ongoing Phase 1/2 clinical trial being conducted by the NIH in older XSCID patients, all of whom had previously received haplo-identical HSCT as infants and were subsequently noted to be experiencing declining immune function with symptomatic infections. At the time of the most recent NIH data presentation at ASH in 2019, 8 patients had been treated without transduction enhancers (referred to as Cohort A) and had been followed for 3 to 7 years. Seven of these 8 patients experienced gradual clinical benefit in terms of clearance of chronic norovirus and associated improved abdominal complaints, malabsorption, growth and IgG production. One of these 7 patients died 27 months after gene therapy of a pulmonary bleed related to chronic bronchiectasis that predated the therapy and was deemed to be unrelated to therapy.
In an attempt to address the relatively slow resolution of chronic norovirus observed in most of these 7 patients and the delayed immune cell recovery and persistent clinical disease in the eighth patient, transduction enhancers were introduced in the cell processing for the subsequent 6 patients (referred to as Cohort B), which included retreatment of the eighth patient in Cohort A who had delayed immune recovery and persistent clinical disease. This enhanced transduction procedure achieved much greater transduction efficiencies than were observed in Cohort A, with greater than 10-fold less vector, and resulted in faster immune reconstitution and more significant clinical benefit by 3 months. As a result, Mustang has licensed Sirion Biotech’s Lentiboost™ and will include transduction enhancement in its pivotal Phase 2 clinical trial for MB-207 in this patient population.
To date, of the 6 Cohort A patients who were alive at the time of the 2019 NIH data readout and who did not undergo repeat therapy, 3 patients have been able to discontinue IVIG and have experienced sustained restoration of humoral responses to immunization. The remaining 3 patients have had reduced IVIG requirements. All chronic norovirus infections have resolved, and the quality of life of all patients has improved significantly.
The original 6 patients in Cohort B also continue to do well, with longest follow-up now 22 months. Two additional patients have been successfully treated with transduction enhancers, for a total of 8 patients in Cohort B. As was the case in Cohort A, no serious adverse events related to treatment were reported other than hematologic related to low-dose busulfan conditioning, and there was no evidence of malignant transformation. Further enrollment at NIH is now limited pending Mustang’s initiation of its pivotal multicenter Phase 2 clinical trial, and the company expects to submit an IND application for this trial in the second quarter of 2021.
