CULVER CITY, Calif., December 20, 2021--(BUSINESS WIRE)--ImmunityBio, Inc. (NASDAQ: IBRX), a clinical-stage immunotherapy company, has successfully raised an aggregate $470 million of equity and debt financing in 2021, with $300 million in new debt financing from NantCapital, LLC. With this new financing from ImmunityBio’s founder, Executive Chairman and Global Chief Scientific and Medical Officer, Dr. Patrick Soon-Shiong, on December 17, 2021, the company is now well positioned to pursue its late-stage clinical portfolio, expand large-scale GMP manufacturing capacity, and advance recruitment of a commercial organization in the urology market.

"In just a short nine months since the formation of ImmunityBio following the merger with NantKwest in March 2021, the progress made in advancing the late-stage clinical platforms in cancer and infectious diseases has been quite remarkable," said Soon-Shiong. "In less than one year, the company has accomplished several important milestones: advanced our Universal Boost COVID T-Cell Vaccine to Phase 3; acquired, developed, and scaled multiple vaccine platforms including DNA to RNA to Subunit proteins; expanded our GMP manufacturing capacity across NK cells, fusion proteins, and RNA vaccines; advanced clinical trial enrollment across pancreatic, breast, and bladder cancers; was selected by the NCI and national cooperative groups for a large Lung-MAP trial; advanced our HIV clinical program globally; and received issuance of seminal cancer vaccine and bladder cancer patents with terms up to 2038."

"With $470 million of financing achieved since the merger, we now have the resources to rapidly advance our late-stage pipeline, build upon our 400,000 sq. feet of GMP biologic, vaccine, and NK manufacturing facilities for 2022 and expand our commercial operations in anticipation of our bladder cancer BLA filing in Q1, 2022," continued Soon-Shiong. "I am proud of the tireless efforts of management and of the entire organization who dedicated their efforts to accomplish these ambitious milestones and I am pleased to support the recently completed financing round."

ImmunityBio now has 21 active clinical trials, 13 of which are in Phase II or III development. In addition, the company has held discussions with the FDA to file a biologics license application (BLA) for Anktiva™ (to be branded VesAnktiva™ for intravesical administration) plus BCG for BCG-unresponsive non-muscle invasive bladder cancer carcinoma in situ (CIS) with a planned data cutoff date of January 2022, under discussions with the FDA. By that date, the median follow-up of patients with high risk CIS BCG responsive disease will exceed 24 months.

ImmunityBio and its scientists published over twenty scientific papers on its immunotherapy portfolio in 2021 and the company has over 750 granted patents for its immunotherapy technologies, including the Nant Cancer Vaccine.

"During the year, management and the clinical, regulatory, scientific, and manufacturing teams made tremendous progress across the board at ImmunityBio. We are advancing our clinical development at an increasing rate with the goal of positioning ourselves to apply for regulatory approval in 2022," said Richard Adcock, President and CEO of ImmunityBio. "With the $300 million financing from NantCapital combined with the equity raised over the last nine months, we have made the decision to pause the At-the-Market offering and we are well positioned to further accelerate development of our oncology and COVID-19 trials— with the goal of bringing these promising technologies to more people in need globally."

Clinical Year-End Review of Strategic Milestones:

1. BCG-Unresponsive Non-Muscle Invasive Bladder Cancer CIS (QUILT 3.032)

The company reported that the primary end points were met for both CIS and Papillary BCG-unresponsive non-muscle invasive bladder cancer in October 2021 with a complete remission rate of 72% and a 12-month disease-free rate of 57%, respectively.

At the end of November 2021, the company provided briefing books and updates to the FDA with November cutoff data showing a 72% complete response rate in the CIS cohort and a median duration of complete response of 24 months. Of note, in those patients who responded to the investigational therapeutic, the probability of avoiding both progression of bladder cancer and cystectomy for over 24 months exceeded 90 percent. The data to the FDA included findings that the combination of Anktiva and BCG had a high safety profile with zero percent treatment-related serious adverse events, zero percent immune related adverse events, and 100 percent bladder cancer-specific overall survival at 24 months. The company plans on a data cutoff in January 2022, which would provide a median follow up in this CIS cohort in excess of 24 months, and anticipates a BLA filing with this final analysis in Q1, 2022.

The papillary cohort continues to accrue and updates will be provided as part of an oral presentation at the ASCO Genitourinary Cancers Symposium in February 2022.

Seminal patents covering intravesical administration of BCG and Anktiva were issued (US 11,173,191 B2 and US 9,925,247 B2) providing term coverage until 2035.

2. Pancreatic Cancer (QUILT 88):

On October 13, ImmunityBio announced that the study’s third cohort, which includes patients with third-line or greater disease, is fully enrolled and of the evaluable patients, 90% (43/48) have exceeded the historical survival rates of approximately two months with standard-of-care chemotherapy. Based on the strength of this early data and the significant unmet medical need, ImmunityBio submitted an amendment to the FDA to increase enrollment in the third cohort ("Cohort C"), and enrollment is actively ongoing. The interim results of Cohort C in the QUILT 88 study have been selected for presentation at the ASCO Gastrointestinal Cancers Symposium, January 2022 in San Francisco and the data to date continues to show that the historical overall survival in patients who have enrolled with 3rd, 4th, 5th and even 6th line metastatic pancreatic cancer exceeds any historical overall survival rate for this advanced stage of disease for which there is no further treatment options available.

3. Natural Killer Cell Platform Advances

A. PD-L1 T-haNK

  • Manufacturing Scale: The company has significantly advanced the manufacturing scale of PD-L1 t-haNK in 2021 and has now achieved 200-liter scale in the last nine months. At this scale, a single manufacturing campaign yields approximately 700 billion PD-L1 t-haNK cells, sufficient for 350 doses. The company has successfully manufactured and cryopreserved trillions of PD-L1 t-haNK cells and is advancing to 500-liter scale in 2022. The company believes it is the first to achieve this large-scale manufacturing capability and capacity in the field of natural killer cells.

  • Clinical Trials with PD-L1 T-haNK:

    • TNBC: The company continues to study this engineered NK-92 cell line in Phase 1 / 2 trials in Triple Negative Breast Cancer to increase effectiveness of Trodelvy (sacituzumab govitecn-hziy) (CT.gov NCT04927884)

    • Metastatic pancreatic cancer to prolong survival rate (CT.gov NCT04390399)

    • Head & Neck Cancer to increase the effectiveness of Keytruda (pembrolizumab) plus N-803 (CT.gov NCT04847466)

  • Mechanism of Action: On March 2021, in collaboration with National Cancer Institute (NCI), ImmunityBio’s PD-L1 t-haNK was reported to be a potent cell therapy agent against myeloid-derived suppressor cells (MDSC) and overcome T cell escape in multiple types of resistant tumors.

B. M-ceNK

  • Manufacturing Scale: The company has achieved a first-in-class manufacturing scale of highly potent natural killer cells isolated from autologous or allogeneic peripheral blood retrieved by an outpatient process of blood withdrawal and separating out white cells, termed apheresis. Over 3,000 percent M-ceNK (memory cytokine enhanced natural killer cells) cell expansion was achieved from a single apheresis. The company has successfully established proprietary proliferation and cryopreservation techniques and this first-generation manufacturing method enables as many as twenty (20) doses of 1 billion M-ceNK cells from a single apheresis. The second-generation manufacturing process has advanced the yield from 20 billion to ~100 billion M-ceNK cells, translating into ~100 doses from a single autologous or allogenic apheresis sample.

  • Clinical Trials with M-ceNK in Solid Tumors: In May 2021, the company announced that the FDA authorized ImmunityBio to conduct a first-in-human trial to study the cryopreserved memory cytokine-enhanced NK cell (M-ceNK) platform in solid tumors. An initial study involving 20 subjects (15 healthy donors and 5 cancer patients) showed that healthy and patient-derived M-ceNK cells killed NK-resistant tumor cells with equal potency as shown in pre-clinical models.

  • Mechanism of Action: In an initial, proof-of-concept clinical study, memory-like NK cells with freshly isolated cytokine-stimulated NK cells demonstrated encouraging results in patients with liquid tumors. These m-ceNK cells, or memory-cytokine enriched NK cells, have been designed for autologous cell therapy, but have also been generated as an allogeneic product from cord blood. The m-ceNK product is characterized as CD56+ cells that are armed with NK cell activating surface receptors required for proliferation, homing and tumor recognition and binding. Both the healthy- and cancer patient-derived m-ceNK cells killed NK-resistant tumor cells with equal potency when tested against tumor cells of different origins, including breast, Merkel, ovarian, adenocarcinoma, and lymphoma.

C. CD-19 t-haNK

  • Manufacturing Scale: Since the June 2019 announcement of FDA authorization to launch the first engineered GMP-grade cryopreserved bi-specific NK cell therapy targeting CD-16 and CD-19 in patients with lymphoma, the merged company undertook manufacturing improvements to scale the product prior to initiation of clinical trials. These advances have been successfully completed and the amended manufacturing process has been submitted to the FDA. CD-19 T-haNK has been manufactured at 200-liter scale and the GMP product is now ready for clinical trials.

  • Clinical Trials: A clinical trial in advanced B cell lymphoma is anticipated to begin in the first half of 2022.

4. N-803 (Anktiva) and Aldoxorubicin Clinical Development in Cancer & HIV

  1. Lung Cancer: In October 2021, ImmunityBio announced that N-803 has been chosen by Lung Cancer Master Protocol (Lung-MAP), a public-private partnership—which includes the National Cancer Institute (NCI), the National Clinical Trials Network (NCTN) Cooperative Groups (SWOG, ECOG-ACRIN, Alliance, and NRG), Friends of Cancer Research, and the Foundation for the National Institutes of Health (FNIH)—to study N-803 (Anktiva) in the Lung-MAP trial.

    ImmunityBio’s study will N-803 (Anktiva) in combination with Merck’s Keytruda (pembrolizumab) in up to 478 second-line patients with tumors that are not targetable with a drug, which accounts for the majority of NSCLC cases.

    In Q4 2021, ImmunityBio received approval from the Institutional Review Board (IRB) overseeing the Lung-Map study to proceed with the trial—one of the National Cancer Institute’s largest lung cancer clinical trials with more than 700 sites.

  2. Pancreatic Cancer, Triple Negative Breast Cancer, Head & Neck Cancer: N-803 and Aldoxorubicin are used in combination with PD-L1 t-haNK in Phase 1 / 2 clinical trials described above.

  3. Glioblastoma: A Phase 1 / 2 trial has been submitted for the study of N-803 and Aldoxorubicin in Glioblastoma. Further progress will be provided in 2022.

  4. HIV with N-803: In June 2021, ImmunityBio announced the opening of a Phase 1 ‘HIV Cure Study’ in patients off therapy and a Phase 2 study in acutely infected patients. Sponsored by the NIAID and AIDS Clinical Trials Group, an "HIV cure study" will evaluate whether Anktiva (N-803) alone or together with broadly neutralizing antibodies can control HIV following interruption of antiretroviral therapy (ART). The Phase 1 open-label, randomized study will enroll 46 people living with HIV whose virus has been suppressed by ART for approximately two years, including at least 30 percent cisgender women or transgender men. A second clinical trial studying Anktiva in HIV is being conducted by the U.S. Military HIV Research Program in Thailand. The Phase 2 study is evaluating Anktiva in combination with antiretroviral therapy (ART) during acute HIV infection as an experimental therapy to target and inhibit early establishment of HIV reservoirs in infected individuals.

    Both studies have opened and patients are actively enrolling. Preliminary data will be reported in 2022.

5. COVID Program to Overcome Spike Variants and Induce T Cell Immunity

Since the inception of the pandemic, ImmunityBio and its scientists have hypothesized that antibody-based vaccines alone are insufficient to prevent transmission and will not overcome viral evolution, resulting in loss of efficacy of antibody-based vaccines with the inevitable development of variants. The company from the onset believed strongly that an immune response generating a combination of antibodies, T cells, and memory B cells is critical to prevent infection, reduce viral load, prevent transmission, provide durable protection and overcome this pandemic.

In order to reduce viral load, T cells are necessary to kill virally infected cells in the nasal and lung passages and thereby prevent transmission even from highly transmissible variants. The non-human primate COVID virus challenge study performed by ImmunityBio in September 2020, supported by BARDA confirmed that ImmunityBio’s second-generation hAd5 S+N vaccine accomplished the goal of reducing viral load following a COVID virus challenge, to non-detectable levels. The study was published on September 2021 in Frontiers in Immunology entitled, "Dual-Antigen COVID-19 Vaccine Subcutaneous Prime Delivery with Oral Boosts Protects NHP Against SARS-CoV-2 Challenge", showing the presence of memory B cells and a rapid antibody response post-challenge with killing of infected cells resulting in no detectable COVID viruses in the nasal and lung passages.

On the basis of these findings, the ImmunityBio program was designed to pursue this strategy of driving T cell and antibody protection, and to develop a second-generation vaccine with broad depth of antigenic coverage. Furthermore, the company pursued a strategy to develop a vaccine that could be manufactured at scale, at low cost, overcome cold-chain distribution issues and provide long-lasting durable protection for the global population. The programs, initiated as early as March 2020, are described below and the initial findings have shown that hAd5 S+N vaccination as a single prime alone induces a 10-fold increase in mean T cell responses in Phase 1 participants and are sustained against spike variants.

Since initiating the initial homologous prime boost trial in October 2020 in the United States, it has become apparent that a "mix-and-match" strategy could provide maximal immune protection. The company has followed this path and the homologous and heterologous portfolio of vaccine platforms are at various stages of clinical development.

  1. Homologous Platform

    Homologous hAd5 S + N Platform
    Prime & Boost:
    In October 2020, the FDA authorized a Phase 1 trial of ImmunityBio’s dual construct Spike + Nucleocapsid (hAd5 S+N) COVID-19 vaccine, designed to drive both T cell and antibody immunity. The company undertook a rigorous development strategy to explore multiple methods of administration (oral, intranasal, subcutaneous, and combinations of each) to determine the best site of delivery to achieve maximum antibody, T cell and mucosal immunity. In February 2021, this trial was expanded to South Africa (The ProVIVA-SA1 Trial). To date, 74 participants have enrolled in the U.S. and South African Phase 1 studies. Data acquisition and analysis from both trials is ongoing. Preliminary analysis has shown that subcutaneous dosing of hAd5 S+N provides strong T cell responses to both Spike and Nucleocapsid antigens with no serious adverse events reported to date. These studies formed the basis of the Universal T Cell Boost Trial (SISONKE Boost Trial) activated in South Africa in July 2021.

    United States Studies: In April 2021, we reported on the preliminary data from the United States trial showing that just a single prime subcutaneous vaccination with our COVID-19 vaccine candidate induced a 10-fold increase in T cell response—equivalent to T cell responses from patients previously infected with SARS-CoV-2. We have also shown that the T-cell responses are maintained against variants, which is critical to providing protection against this ever-changing virus. In light of the FDA Guidance to the industry regarding risks of thrombosis with thrombocytopenia syndrome (TTS) that were observed with other adenoviral vectored COVID-19 vaccines, the FDA requested that ImmunityBio provide multiple risk mitigations and management measures, which ImmunityBio did and incorporated into all new COVID-19 study protocols, lifting all clinical holds. The immunogenicity assays from the U.S. trials are being validated and this process is expected to be completed in Q1 2022. The ongoing U.S. trials will be completed as planned with the subjects who have been enrolled.

  2. Heterologous Mix-and-Match Program

    ImmunityBio has acquired the rights to multiple platforms and initiated a consortium including Baylor Medical College, Infectious Disease Research Institute (IDRI), Amyris, Inc. and EnGeneIC to develop, manufacture and scale second-generation vaccines that combine different advanced DNA, RNA, protein constructs, and adjuvants. The company has adopted a long-term approach to addressing COVID and future pandemics and believes these mix-and-match components are critical to providing accessible, broad, and durable protection against current and future variants such as Delta and Omicron variants.

    "Developing a novel vaccine candidate during a global pandemic has been challenging for a number of reasons, which have affected all drug developers," said Soon-Shiong. "When we first announced our intent to develop a COVID-19 vaccine in April 2020, we indicated a vaccine that generates long-lasting, cell-mediated T cell immunity would require the use of genomics, molecular dynamics, and new vectors. We also hypothesized that a heterologous approach (mix-and-match) would strengthen immune response. Almost two years into the pandemic and dozens of virus mutations later, these predictions are proving more accurate than ever, which is why we are partnering with IDRI, Amyris, Inc., EnGeneIC, and the Baylor College of Medicine to develop next generation mRNA, recombinant protein vaccine candidates and first-in-class invariant NK-T Cell (iNK-T) COVID vaccines. We anticipate being able to move quickly to enroll participants in our COVID-19 trials in South Africa and Botswana and, ideally, bringing a highly effective vaccine to market in the next 12-18 months."
    ImmunityBio has undertaken the strategy that a mix-and-match approach of different vaccine platforms (DNA, RNA and subunit proteins) would provide the strongest durable immunity and allow large-scale manufacturing, mitigating supply chain limitations of any single platform. To execute on this strategy, the company announced in November 2021, expansion of its vaccine program.

    1. Heterologous SISONKE Universal Boost T Cell Trial (South Africa):
    J&J Ad26 Prime + hAd5 S + N Boost Enters Phase 3

    The SISONKE Universal Boost T Cell Trial was the first DNA / DNA heterologous mix and match trial of Ad26 and hAd5. The Phase 1 / 2 / 3 trial was designed to study the efficacy, safety, and immunogenicity of ImmunityBio’s T-Cell COVID-19 vaccine as a boost in participants who have already received a spike-only antibody-based vaccine. The study is designed to explore whether the T-cell-based vaccine could prevent breakthrough infections from the Delta variant in health care workers who are already vaccinated. The goal of the hAd5 S+N vaccine is to potentially provide increased protection and long-term immunity against the multiple variants and multiple waves affecting South Africa and other countries. Phase 1 studies of subcutaneous dosing in U.S. have demonstrated no serious adverse events and potent T-cell responses after a single prime dose.

    The SISONKE Universal Boost Phase 2 trial is fully enrolled with 60 participants with no serious adverse events. The Phase 3 trial is now open and enrollment will begin in January 2022.

    2. Heterologous THEMBA Trial (South Africa):
    SASA RNA Prime + hAd5 S+N Boost

    The THEMBA trial is the first heterologous RNA / DNA prime boost study of self-amplifying self-adjuvating RNA (SASA-RNA), next-generation nano-lipid carriers with hAd5 S+N. The trial is under regulatory review at SAHPRA and the company is awaiting authorization to begin the study in South Africa.

    3. Heterologous PULA Trial (Botswana):
    SASA RNA Prime + Nabisome EDV or RBD Subunit Protein Boost

    Nabisome (EDV) Platform: In November 2021, EnGeneIC and ImmunityBio signed an exclusive, worldwide license agreement to develop the first invariant NK – T (iNK-T) cell vaccine for the treatment of COVID. This nano cell technology, termed Nabisome EDV, is now in Phase 1 clinical trials in Australia. To date, the initial dose of 2x109 EDV IM dose has been shown to be safe with promising antibody, memory B cell and T-cell activity. ImmunityBio plans to expand this trial in Australia and the U.S. and use Nabisome in combination with SASA RNA in the PULA trial in Botswana. The PULA Mix-and-Match Trial will be submitted Q4 2021 for regulatory review.

    RBD Recombinant Protein Subunit + Adjuvant Platform: In November 2021, ImmunityBio announced it had licensed a recombinant protein COVID-19 vaccine (RBD Subunit) candidate from Baylor College of Medicine, which was developed at the Texas Children’s Hospital Center for Vaccine Development. Protein-based vaccines have long been used to confer immunity against hepatitis B and human papillomavirus (HPV), as immune responses often target proteins that are part of viruses and bacteria. This recombinant protein vaccine technology is proven and well-established. Production of these vaccines can be easily scaled up in low-resource countries. Paired with powerful adjuvant formulations developed by IDRI and partners, protein-based vaccines can provide broad protection against multiple coronavirus variants and are stable at room temperatures. ImmunityBio will lead development, manufacture scale up and commercialization of the recombinant protein vaccine candidate in South Africa.

  3. Vaccine Manufacturing Capacity
    ImmunityBio has expanded manufacturing capacity for each of these platforms (hAd5, SASA RNA, Adjuvants, and RBD subunit) in the U.S., as well as secured manufacturing sites in South Africa and Botswana with strategic collaborators. The SASA RNA manufacturing capacity will support the ImmunityBio/Amyris COVID-19 joint venture.
