GAITHERSBURG, Md. and SHANGHAI, Aug. 30, 2022 /PRNewswire/ -- I-Mab (the "Company") (Nasdaq: IMAB), a clinical-stage biopharmaceutical company committed to the discovery, development, and commercialization of novel biologics, today announced financial results for the six months ended June 30, 2022, and provided key business updates.
During this reporting period, the Company has implemented a series of strategic initiatives that aim to re-position its overall business priorities to focus on key value drivers while preserving a strong cash position estimated to be sufficient to support its key business operations for more than three years.
Specifically, the Company will continue to drive value by leveraging its global R&D competitive advantages in immuno-oncology, which has been demonstrated in the Company's short history with such examples as lemzoparlimab, uliledlimab and TJ-CD4B. Today, our pipeline is not only innovative but also advanced as certain key assets move towards BLA and near-term commercialization, including felzartamab and eftansomatropin alfa. The Company's current business model relies on a two-pillar approach to realize the value of innovation. The first pillar is to partner out the global rights of its innovative assets after global phase 1 or phase 2 clinical validation while retaining the rights for clinical development, manufacturing, and commercialization in China. This is exemplified by the global partnership with AbbVie for lemzoparlimab. The Company will continue to pursue more partnership opportunities for other global assets in its pipeline. The second pillar is to rapidly develop the assets towards BLA and commercialization in China and then partner with large pharmaceutical companies which have well-established sales forces and proven commercialization capabilities to market the products in China. This approach is exemplified by the commercial partnership with Jumpcan for eftansomatropin alfa. The Company is seeking similar commercial partnerships for other late-stage assets, including felzartamab. In addition to the broad strategic approach outlined above, the Company is committed to the following:
Firstly, following a systematic review of its pipeline development and overall business, the Company has prioritized its resources to focus on five key clinical stage assets with 10 ongoing and planned clinical trials. These prioritized programs represent the Company's key value drivers as significant progress in these prioritized programs will not only accelerate the clinical development towards pivotal or registrational studies (such as lemzoparlimab and uliledlimab) but also facilitate global business development deals. The Company is currently pursuing potential global partnership deals for uliledlimab and TJ-CD4B.
Secondly, the Company's current commercialization strategy aims to maximize the commercial value of its pre-BLA products through commercial partnerships typically structured with upfront, regulatory, and sales milestone payments along with significant sales royalties. A commercial partnership for eftansomatropin alfa was established with Jumpcan in 2021 and is progressing as planned. By doing so, the Company is able to avoid investing significant resources to build its sales forces and instead allocate the resources to deliver the value-driver milestones or catalysts. The Company is currently pursuing a similar commercial partnership for felzartamab.
Thirdly, the Company will continue to invest in the discovery and development of its next-generation pipeline assets. I-Mab's next-generation innovative pipeline is strategically designed and driven by cutting-edge science and technology, with a focus on first-in-class and best-in-class potential. Multiple novel assets focusing on innovative bi-specific antibodies and cytokine-based immune adjuvants are on track to advance towards an IND enabling stage with a goal to achieve four to five INDs or Phase 1 study initiations around 2025.
Fourthly, through a strategy of re-positioning the pipeline to prioritize key assets with high probability of commercial success, the Company has been making significant efforts to preserve its strong cash position. As of June 30, 2022, the Company had a total cash position, consisting of cash, cash equivalents, and short-term investments, of US
"As we weather turbulent market conditions worldwide, we must prioritize our resources to focus on value-driving assets while continuing to deliver on key milestones and strengthening the Company's fundamentals," said Dr. Jingwu Zang, Founder, Chairman, and Acting CEO. "We have achieved seven critical clinical milestones year-to-date, including positive data readouts for lemzoparlimab, uliledlimab and TJ-CD4B. In our pipeline development, we have also made significant progress on lemzoparlimab. Phase 2 data will be presented in a proffered presentation at the upcoming European Society for Medical Oncology (ESMO) Congress in September, and we are on track to initiate a registrational trial in China by the end of 2022. We expect to see additional data from the expanded phase 2 study of uliledlimab in the fourth quarter of 2022."
Dr. Zang added, "Another key focus is the current registrational studies towards anticipated BLAs between now and 2024 and subsequent commercialization for felzartamab and eftansomatropin alfa. We have a clear strategy to focus on creating value for our shareholders while preserving a strong cash position to support our key business operations for over three years."
"On the corporate development front, business development remains a key strategic priority for the Company, and we continue to pursue potential partnership opportunities. Looking ahead, we remain confident in achieving critical clinical and corporate milestones by year-end to continue to create value for our stakeholders." Dr. Zang concluded.
Updated Pipeline Development Highlights and Upcoming Milestones
The Company's drug pipeline has a number of critical features: (1) The pipeline is innovative and globally competitive, comprised of three generations of products with first-in-class and best-in-class potential. This is exemplified by the first generation of differentiated drug assets, such as felzartamab and eftansomatropin alfa, which are in registrational trial or at a pre-BLA stage, as well as novel monoclonal antibodies such as lemzoparlimab and uliledlimab, which are in phase 2 clinical trials or preparation for phase 3. The second generation of even more innovative bi-specific antibody assets, including TJ-CD4B and TJ-L14B, are in phase 1 clinical trials, followed by additional bi-specific antibody assets progressing towards an IND enabling stage. The new discovery initiatives for the third-generation innovation are on the way for high-risk and high-value drug candidates enabled by transformative technologies. (2) The pipeline is focused on immuno-oncology and biologics, leveraging its unique R&D and CMC strengths. (3) The pipeline is advanced with three assets are either in phase 3 or registrational studies or planned for phase 3. The Company expects to achieve three potential BLA submissions or market launches between 2023 and 2025.
The chart below summarizes the development status of the Company's clinical stage pipeline (pre-clinical programs are not shown).
(1) Five prioritized clinical assets:
Lemzoparlimab (Phase 3 planned): The current focus is on the combination therapy of lemzoparlimab with azacytidine (AZA) for the treatment of newly diagnosed myelodysplastic syndromes (MDS) with the goal of being first-to-market in China. The probability of success is supported by collective safety data based on nearly 200 patients from multiple clinical trials and the positive efficacy data, especially from the phase 2 study in patients with MDS. Active communications are ongoing with the China CDE and NMPA for the initiation of a registrational trial by the end of 2022, depending upon the regulatory process and the preparation of the clinical sites around the country. In parallel, two other studies, including solid tumor indications are ongoing.
Clinical development progress and update on global strategic partnership with AbbVie. Lemzoparlimab, a novel CD47 antibody developed by the Company, is being investigated through a comprehensive clinical development plan for hematologic malignancies and solid tumors. The Company's near-term priority is to initiate a phase 3 registrational trial in newly diagnosed higher-risk MDS patients by Q4 2022, potentially making lemzoparlimab the first CD47 product in China. I-Mab is currently leading three clinical studies of lemzoparlimab, with about 200 patients treated across different indications. Safety Data. Overall, the safety data from multiple clinical trials in the U.S. and China involving nearly 200 cancer patients have demonstrated a good safety profile of lemzoparlimab without the need for a priming dose regimen. Efficacy Data. Lemzoparlimab has shown encouraging efficacy signals in different tumor indications from multiple clinical trials. In particular, recent phase 2 data from lemzoparlimab combination therapy with AZA indicated that lemzoparlimab exerted a comparable level of clinical efficacy with magrolimab in a similar therapeutic setting as described below.
- Lemzoparlimab in combination with AZA for AML and MDS: Over 90 patients with newly diagnosed MDS or acute myeloid leukemia (AML) have been dosed with lemzoparlimab at 30 mg/kg in combination with AZA in China. This patient cohort had a more severe disease at baseline due to disease conditions and clinical practice patterns in China. I-Mab's recent data analysis of the MDS cohort, including over 50 patients who received the combination treatment, showed that without a priming dose, lemzoparlimab was well tolerated. The Company observed significant clinical responses as defined by the overall response and complete response rates, which improved over time (Figure 1). Detailed safety and efficacy data, along with gene mutation analysis, will be presented in a proffered paper at the European Society for Medical Oncology (ESMO) Congress 2022.
Phase 3 clinical trial of lemzoparlimab in combination with AZA as a 1L treatment for MDS. An end-of-phase 2 (EOP2) meeting request was submitted to China CDE and NMPA and discussion is ongoing with CDE to initiate a phase 3 clinical trial in patients with MDS by the end of 2022.
Lemzoparlimab in combination with rituximab for non-Hodgkin's lymphoma (NHL): The dose expansion trial is ongoing to enroll more patients. The preliminary data were reported at ASH 2021.
Lemzoparlimab in combination with PD-1 therapy for solid tumors: Phase 2 clinical trial in combination with a PD-1 antibody (pembrolizumab or toripalimab) are ongoing in patients with selected advanced solid tumors.
Update on AbbVie partnership: On August 15, 2022, the Company and AbbVie entered into an amendment to the original license and collaboration agreement dated September 3, 2020 between the parties on CD47 antibody therapies (as amended, the "Agreement"). Both parties will continue to collaborate on the global development of anti-CD47 antibody therapy under the Agreement. The Company will be eligible to receive, and AbbVie will pay, up to US
The Company continues its commitment to lemzoparlimab development based on the accumulative safety data, without the need for a priming dosing regimen, from nearly 200 cancer patients as well as the efficacy data, especially from a Phase 2 study of combination therapy of lemzoparlimab and AZA in patients with higher risk MDS. The detailed data will be presented in a proffered paper at the European Society for Medical Oncology (ESMO) Congress in September 2022. The Company is on track to initiate a Phase 3 clinical trial in patients with MDS in China as planned.
AbbVie has discontinued the global Phase 1b study of lemzoparlimab combination therapy with AZA and venetoclax, in patients with MDS and AML. This decision was not based on any specific or unexpected safety concerns.
Uliledlimab (End of Phase 2, Pivotal Study Planned in 2023): A highly differentiated CD73 antibody being developed for solid tumor indications. The Company is currently advancing uliledlimab in two phase 2 clinical trials in the U.S. and China in selected tumor types for clinical proof-of-concept. The current development focus is on non-small cell lung cancer (NSCLC) as a combination therapy with a PD-1 antibody to aim for the potential initiation of a pivotal clinical study in 2023.
Phase 2 clinical study of uliledlimab in combination with PD-1 antibody (toripalimab) in advanced NSCLC: The Company presented the preliminary clinical results of an ongoing phase 2 clinical study of uliledlimab in combination with toripalimab (TUOYI®) in patients with NSCLC at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting. The results are largely consistent with those observed in phase 1 clinical trial in relation to favorable safety, pharmacokinetics (PK), and pharmacodynamic (PD) profile of uliledlimab. Uliledlimab appears safe and well-tolerated up to the highest doses tested at 30 mg/kg Q3W, as a monotherapy and as a combination therapy with toripalimab with no dose limiting toxicity (DLT). Uliledlimab exhibited a linear PK profile at doses ≥ 5mg/kg and a dose-dependent receptor occupancy with no "hook effect" where the antibody loses its effectiveness at high concentrations.
The phase 2 preliminary efficacy data as of March 29, 2022, are summarized as follows. Among the three NSCLC patient cohorts who were under different treatment settings, clinical responses varied. The highest clinical response rate was observed in the patient cohort with advanced NSCLC (mostly stage 4 disease) who were previously ineligible for standard of care treatment. Among 19 efficacy evaluable patients from this cohort, 5 partial responses (5 PR, overall response rate [ORR]=
Based on the preliminary data mentioned above, the phase 2 clinical trial was expanded to focus on enrolling the selected patient cohort with advanced NSCLC who were previously ineligible for standard of care treatment for further evaluation of treatment efficacy as well as the role of CD73 as a potential predictive biomarker.
The current status of the expanded phase 2 clinical trial in patients with NSCLC: As of August 2022, 47 patients have been enrolled in this expanded cohort, and more data are being collected. At a high level, the new data have further confirmed the compelling safety and encouraging efficacy signals as well as the correlation between high tumor expression of CD73 and clinical response in patients with NSCLC. The Company's goal is to speed up the expanded phase 2 study and complete the target enrollment of 60 patients within the next two months. A more complete dataset is expected by Q4 2022. The Company is seeking a suitable opportunity to present the new dataset either by the end of 2022 or early 2023. In parallel, the company is in the process of exploring a potential global partnership deal.
Development of companion diagnostic (CDx) kit of CD73: Based on the correlation data between clinical response and tumor CD73 expression, I-Mab is collaborating with WuXi Diagnostics to develop a standardized companion diagnostic kit of CD73 to be employed in the planned pivotal clinical trial in 2023.
Felzartamab (BLA ready for 3L MM, Phase 3 for 2L MM): A differentiated CD38 antibody for the treatment of relapsing and refractory multiple myeloma (MM) and potentially autoantibody-mediated autoimmune diseases such as membranous nephropathy. A new combination therapy with lemzoparlimab for high-risk MM is being investigated pre-clinically. The Company owns the rights for the development, manufacturing, and commercialization of felzartamab in Greater China from MorphoSys.
Felzartamab is positioned as the first and only locally manufactured CD38 antibody to be commercially more competitive in China. Although the current BLA plan is based on an imported drug license application, the Company has a manufacturing plan by leveraging the manufacturing facility held by I-Mab Biopharma (Hangzhou) Limited ("I-Mab Hangzhou"), an unconsolidated investee of the Company, for future commercial production with potentially low cost of goods.
China BLA ready for third-line MM: The registrational trial has been completed, and the topline data have met the preset primary and secondary endpoints. More importantly, the clinical data have confirmed the clinical advantages of felzartamab in terms of lower infusion-related reaction rate and shorter infusion time, which has made it possible for its use in an outpatient clinic setting. In January 2022, the Company signed a partnership agreement with the Hangzhou Qiantang Government in China to manufacture felzartamab locally to accelerate its commercialization. The local manufacturing plan is expected to significantly reduce the cost of goods and render felzartamab commercially more competitive. The Company is exploring potential commercial partnership for felzartamab in China, which, if successful, will enable the Company to maximize the value of felzartamab while avoiding investing significant resources in building up commercialization capability at this time.
China phase 3 trial as a second-line treatment for MM: Patient enrollment for a randomized, open-label, parallel-controlled phase 3 registrational trial of felzartamab in combination with lenalidomide as a second-line treatment for MM was completed in September 2021. The topline data package, if fully matured in 2023, is expected to support a potential BLA submission.
New potential combination therapy with lemzoparlimab: CD47 is consistently and highly expressed on MM tumor cells expressing various levels of CD38; the Company investigated the possibility of combining felzartamab with lemzoparlimab for a more effective treatment for MM in a pre-clinical setting. The results supported that the combination therapy has a synergistic effect on MM. The data have been submitted to ASH 2022 for presentation.
Eftansomatropin alfa (Phase 3, BLA ready in 2023): A differentiated long-acting growth hormone for pediatric growth hormone deficiency (PGHD). Eftansomatropin alfa is the only rhGH in its proprietary fusion protein format (pure protein-based molecule) without chemically linking with PEG or other moieties. Its safety, tolerability, and efficacy have been well demonstrated in a phase 2 clinical trial in the EU. The Company has the rights for the development, manufacturing, and commercialization of eftansomatropin alfa in China from Genexine.
Phase 3 clinical trial for PGHD: This phase 3 registrational trial (TALLER) of eftansomatropin alfa as a weekly treatment for PGHD patients is ongoing in China. On May 31, 2022, the Company announced the completion of patient enrollment in the TALLER study for treatment of PGHD. TALLER is a multi-center, randomized, open-label, active-controlled phase 3 clinical study (NCT04633057) that has enrolled 168 patients in China. The study aims to evaluate the efficacy, safety, and pharmacokinetics (PK) of eftansomatropin alfa in PGHD, as compared to Norditropin®, a daily rhGH marketed in China. Following the completion of the enrollment in May 2022, the final dataset from the TALLER study is anticipated in Q3 2023, which is expected to be followed by a BLA submission in Q4 2023 or Q1 2024.
Strategic commercial partnership with Jumpcan: In November 2021, the Company announced a strategic commercial partnership with Jumpcan, a leading domestic pharmaceutical company specializing in and committed to pediatric medicines, to accelerate the commercialization of eftansomatropin alfa. I-Mab will be the marketing authorization holder (MAH) of the product and supply the product at an agreed cost rate to Jumpcan. Jumpcan will be responsible for commercializing the product and developing new indications in collaboration with I-Mab in mainland China. Jumpcan has made an upfront payment of RMB224 million to I-Mab. Further, upon achievement of development, registration and sales milestones, I-Mab will be eligible to receive milestone payments in aggregate of up to RMB1.792 billion and total non-royalty payments up to RMB2.016 billion. In addition, I-Mab and Jumpcan will share profits generated from the commercialization of the product in mainland China on a 50/50 basis, pursuant to which I-Mab will be entitled to receive tiered low double-digit royalties on net sales. This partnership deal represents one of the largest in China's biopharma market.
TJ-CD4B/ABL111 (Phase 1): A novel Claudin 18.2 and 4-1BB bi-specific antibody is composed of a highly potent Claudin18.2 IgG with high binding affinity even in Claudin18.2 low-expressing tumors and a unique 4-1BB scFv which could stimulate T cells only upon tumor cell engagement to avoid systemic and liver toxicity. TJ-CD4B is designed to treat patients with Claudin18.2 positive gastric and pancreatic cancer. In March 2022, the Company received FDA Orphan Drug Designation for TJ-CD4B for the treatment of gastric cancer, including cancer of the gastroesophageal junction.
Phase 1 clinical trial of TJ-CD4B in patients with advanced or metastatic solid tumors: The dose escalation part of the study reached 8 mg/kg without encountering dose limiting toxicity. More data are being generated as the trial progresses. As of Q2 2022, 5 dose cohorts had been completed, with 16 subjects dosed. Regarding safety, no grade 2 TRAEs or DLTs were reported. There is a dose-dependent increase of drug exposure and soluble 4-1BB in serum, suggestive of a favorable PK/PD profile and potentially a longer dosing interval with durable T cell activation. Preliminary clinical activity was also observed, with one confirmed PR of a metastatic esophageal adenocarcinoma patient who failed three lines of prior therapies, including PD-1 therapy, and three cases of stable disease (SD). The study is currently at 8 mg/kg without significant toxicities. Additional clinical sites in China joined this phase 1 international multi-center clinical trial, with the first patient dosed at 5 mg/kg in July 2022.
(2) Other clinical assets
Efineptakin alfa (Phase 2): The world's first and only long-acting recombinant human interleukin-7 ("rhIL-7") and is designed as a monotherapy for the treatment of cancer patients with lymphopenia because of its unique properties of increasing tumor-attacking T cells and as a combination with a PD-1 or PD-L1 antibody because of its potential synergism with PD-1/PD-L1 therapy. The Company has the rights for the development, manufacturing, and commercialization of efineptakin alfa in Greater China from Genexine.
Phase 2 Clinical Trial: the first patient was dosed in a phase 2 study of efineptakin alfa (also known as TJ107) in combination with pembrolizumab (Keytruda®) in patients with advanced solid tumors in January 2022. The study follows a "basket" trial design to include selected tumor types, including triple-negative breast cancer (TNBC) and squamous cell cancer of the head and neck (SCCHN).
Clinical data published by Genexine/NeoImmuneTech: (1) According to the data from the NIT-110 dose-escalation trial presented at ASCO 2021, the combination of efineptakin alfa and pembrolizumab is safe and well-tolerated in patients with advanced solid tumors. It significantly increased T cell numbers in both tumor specimens and the peripheral blood in patients treated with efineptakin alfa. (2) Data from phase 1b/2 Keynote-899 study, presented at ASCO 2022, showed that combination treatment of efineptakin alfa with pembrolizumab (Keytruda®) induced ORR of
Plonmarlimab (TJM2): a monoclonal antibody targeting human granulocyte-macrophage colony-stimulating factor (GM-CSF), a cytokine that plays a critical role in acute and chronic inflammation and cytokine release syndrome (CRS) associated with CAR-T and severe COVID-19.
CRS associated with severe COVID-19: In August 2021, the Company reported positive interim analysis from the phase 2/3 trial of plonmarlimab to treat patients with severe COVID-19. Plonmarlimab treatment resulted in a higher mechanical ventilation free (MVF) rate (
Enoblituzumab (TJ271): A humanized B7-H3 antibody as an immuno-oncology treatment agent. Enoblituzumab works through a dual mechanism to attack tumor cells, i.e., ADCC and immune activation. The Company licensed the rights for the development and commercialization of enoblituzumab in Greater China from MacroGenics, Inc. ("MacroGenics") under a collaboration agreement (as amended from time to time, the "MacroGenics Agreement"). The Company originally planned a phase 2 clinical trial of enoblituzumab in combination with pembrolizumab (Keytruda®) in patients with selected solid tumors, including NSCLC, bladder cancer and melanoma, in China, but has not enrolled any patient in the trial. In July 2022, due to an unexpected high incidence of fatal bleeding, MacroGenics terminated a phase 2 study of enoblituzumab as a combination therapy with PD-1 antibody or PD-1/LAG3 bispecific antibody in patients with head and neck cancers. The Company exercised its right to terminate the MacroGenics Agreement by serving a termination notice on August 29, 2022, which termination will take effect in 180 days after the date of the notice.
TJ210/MOR210: A novel monoclonal antibody targeting C5aR1 to treat solid tumors through the suppression of myeloid-derived suppressor cells and modulation of tumor microenvironment in favor of enhanced anti-tumor immune response as a novel mechanism of action. The in vitro and in vivo pre-clinical studies are ongoing to explore and validate the most effective combination partner(s) of TJ210 in addition to the PD-(L)1 antibody. I-Mab has the rights for the development, manufacturing and commercialization of TJ210 from MorphoSys in Greater China and South Korea, and co-develops the asset globally with MorphoSys. Phase 1 clinical trial in patients with advanced solid tumors: The phase 1 study is ongoing in the U.S., and patient recruitment for dose escalation will be completed in Q3 2022. In addition, the clinical study report of this phase 1 study is expected in Q4 2022. The phase 1 clinical trial in Chinese patients has been approved by China NMPA. Currently, no active clinical study is ongoing.
TJ-L14B/ABL503: A novel PD-L1-based bispecific antibody with the PD-L1 arm to target PD-L1+ tumor cells and block PD-L1/PD-1 interaction and the 4-1BB arm to conditionally activate T cells upon local tumor engagement. Phase 1 clinical trial in patients with advanced solid tumors: Dose escalation of TJ-L14B monotherapy is ongoing in the U.S. in patients with advanced or metastatic solid tumors. More data are being generated as the trial progresses.
(3) Preclinical assets and programs
The Company's R&D strategy to sustain and enrich the growing innovative immuno-oncology pipeline is to generate the next generation of innovative assets enabled by cutting-edge science and technology. The goal is to achieve four to five INDs or phase 1 clinical trials within the next three years by focusing on bi-specific antibodies and so-called "super antibodies" that are enabled by new technologies, such as mRNA technology, or formatted with novel modalities such as the masking technology. Innovative immune adjuvants to activate both innate and adaptive anti-tumor immunity are also being developed. The Company has made steady progress in advancing the development of these preclinical assets culminating in successful candidate selection of two bispecific molecules early this year and another 4 molecules expected to achieve candidate selection in the near future. Two leading molecules are described below.
TJ-L1IF is a novel PD-L1/IFN-α antibody-cytokine fusion protein, which is specifically designed for the treatment of PD-1/PD-L1 resistant tumors through the addition of a strong immune adjuvant (interferon-alpha, IFN-α) to potentially convert "cold" tumor to "hot" tumor on top of a PD-L1 antibody to achieve superior anti-tumor activity than PD-(L)1 antibody monotherapy. Novel drug molecules with such design is badly needed to address the current clinical challenges where a majority of cancer patients do not or poorly respond to PD-1/PDL-1 therapies.
IFN-α was the first cytokine approved for cancer treatment, but its clinical use is highly limited due to considerable systemic toxicity. TJ-L1IF is composed of a PD-L1 VHH nanobody linked with the Fc of human IgG with an engineered IFN-α2b fused at the C-terminus. It is a prodrug in that the IFN-α2b moiety is masked by a PEG group through a protease-cleavable linker rendering the drug inactive in the systemic circulation, thus strongly reducing systemic toxicity. Once the drug accumulates at the tumor site by PD-L1 antibody targeting, the linker is cleaved by proteases that are highly expressed in the tumor environment to achieve specific activation only at the tumor site. This unique property of TJ-L1IF has been confirmed in a series of in vitro and in vivo studies, in which TJ-L1IF demonstrated plasma stability, good safety in cynomolgus monkeys, and superior anti-tumor activity in the PD-1/PD-L1 resistant tumor models, than that achieved by PD-L1 antibody or IFN-α used either alone or in combination. After the first dose of treatment, the active format of the drug was quickly detected and accumulated in the tumor but not in the periphery, confirming the local delivery and conversion to an active form of IFN-α at the tumor site (Figure 2). TJ-L1IF was developed using Affinity's TMEA technology and is now under pre-clinical development.
TJ-C64B is the Company's third bispecific molecule being developed by leveraging a conditional 4-1BB platform which has the advantage of minimizing liver toxicity with an increased therapeutic window. It is specifically designed to simultaneously target Claudin 6 (CLDN6), uniquely expressed in specific cancer types, including ovarian cancer cells, and 4-1BB expressed by T cells to mediate the T cell killing of CLDN6+ tumor cells. CLDN6 is hardly detectable in normal adult tissues to ensure treatment specificity for ovarian cancers. The Company has achieved candidate selection and is actively progressing the pre-clinical development of the candidate molecule.
TJ-C64B activates T cells through 4-1BB stimulation only upon CLDN6 engagement, providing a localized immune activation in tumors with expected efficacy and reduced systemic toxicity. Owing to a competent Fc, TJ-C64B has an added advantage of specifically depleting CLDN6-expressing tumor cells and intra-tumor regulatory T cells highly expressing 4-1BB, which differentiates it from other 4-1BB bispecific antibodies under clinical development. As published in AACR 2022, pre-clinical data showed that TJ-C64B enhances CLDN6-dependent T cell activation upon the engagement of cancer cell lines with different CLDN6 expression levels. In a syngeneic mouse model, TJ-C64B treatment induces strong anti-tumor activity with complete tumor regression in all tested mice at the dose of 4.5 mg/kg and long-term protection from tumor re-challenge through the immunological memory response. Further, ex vivo analysis confirms localized immune activation by TJ-C64B as evident by the increased CD8+ T cells, specifically those residing in tumors (Figure 3). TJ-C64B is now under pre-clinical development and the Company plans to submit an IND in the U.S. around mid-2023.
Furthermore, the third wave of innovation initiatives launched in 2021 is making good progress, with multiple innovative molecules now in candidate selection and pre-clinical stage. Among these programs, immune adjuvants are an area of focus designed to prime and amplify both innate and adaptive immune responses. The immune adjuvant portfolio is comprised of cytokine fusions and immuno-cytokines. The cytokine fusions are engineered to extend half-life with Fc fusion and detune the binding affinity and potency of natural cytokine for better safety and efficacy with site-specific mutation. The immuno-cytokines are designed to conjugate engineered cytokines e.g. by masking technology to the tumor or immune cell targeting antibody to achieve pro-longed half-life, minimal systemic toxicity, and enhanced activity by selective tumor targeting.
This growing new portfolio of novel drug candidates represents the Company's strong commitment to sustaining the global competitiveness of its pipeline through continued innovation.
Business Development and Partnership Deals
(1) Research partnerships at I-Mab are aimed at building up the next wave of innovative assets that are enabled by cutting-edge scientific research and new transformative technologies. Firstly, I-Mab collaborated with selected academic groups to investigate the new regulatory pathways involved in the activation and suppression of multiple immune cells (e.g. myeloid cells) in the tumor microenvironment, leading to the identification of new targets that can complement PD-1/PD-L1 antibody or overcome the resistant mechanism of immune checkpoint inhibitor treatment. Secondly, the Company continues to actively seek out opportunities to partner with other biotech companies which are specialized in the development of unique technology platforms in the field of protein design, engineering, and delivery. In the first half of 2022, the Company achieved three early-stage collaborations to co-develop novel antibody products in new modalities by leveraging the proprietary technologies of each partner. Moreover, in terms of the collaboration of translational research, the Company reached an agreement with WuXi Diagnostics to develop a standardized CD73 in vitro diagnostic (IVD) kit to accompany the ongoing phase 2 and planned phase 3 clinical studies with uliledlimab.
(2) Commercial partnerships are designed as the key model for near-term commercialization of upcoming products, including felzartamab and eftansomatropin alfa. For eftansomatropin alfa, the Company has been working closely with its commercial partner, Jumpcan, to prepare for the product launch and the subsequent local manufacturing plan. The Company is working towards a similar commercial partnership for felzartamab with an aim to maximize the value of felzartamab without investing heavily to build up its own sales capability.
(3) Out-licensing deals continue to remain one of the Company's corporate priorities. The Company is currently pursuing potential global partnership deals of uliledlimab and TJ-CD4B.
Near-Term Product Commercialization
With the rapid progress in clinical development, the Company's most advanced assets, i.e. felzartamab, eftansomatropin alfa, and followed by lemzoparlimab, are expected to potentially achieve BLA in China in the next two to three years.
For felzartamab, there are about 20,000 newly diagnosed MM patients in China every year, and patients with refractory or relapsed MM who are eligible for 2L and 3L treatment are about 100,000[1]. Product advantages of felzartamab in lower injection reaction rate and shorter infusion time for out-patient use, together with its advantage as potentially the first locally manufactured CD38 antibody product, put it in a competitive position in China. The Company plans to partner with a leading domestic pharmaceutical company with a well-established sales force and proven commercialization capabilities to market felzartamab in China.
For eftansomatropin alfa, approximately 3.4 million children suffer from growth hormone deficiency (PGHD) in China[2]. Eftansomatropin alfa is the only pure protein-based long-acting GH with no pegylation or chemical linkers, which potentially offers a favorable safety profile. With its unique product advantages, among the few long-acting growth hormone players, and Jumpcan's commercial leadership in pediatric therapeutic area in China, eftansomatropin alfa has the potential to become a major player in China growth hormone market.

Updates Regarding Holding Foreign Companies Accountable Act (HFCAA)
During the last six months, the Company has completed the process of evaluating and selecting a U.S. based public accounting firm that is subject to inspection by the Public Company Accounting Oversight Board (the "PCAOB") for the preparation of its audit reports commencing from the fiscal year of 2022. On August 26, 2022, the PCAOB signed a Statement of Protocol with the China Securities Regulatory Commission and the Ministry of Finance of the People's Republic of China relating to inspections and investigations by the PCAOB of audit firms based in mainland China and Hong Kong. I-Mab has noted this positive progress and will closely follow the development under the Statement of Protocol, which is expected to be executed in steps and may ultimately mitigate delisting risks under the HFCAA. In parallel, the Company will continue working on and is prepared to effect, as a contingency plan, the change of its auditor to the foregoing US based public accounting firm in the event that the progress of Statement of Protocol does not meet the deadline for the Company to mitigate the delisting risk in the 2022 financial report.

Use of Non-GAAP Financial Measures
To supplement its consolidated financial statements which are presented in accordance with U.S. GAAP, the Company uses adjusted net income (loss) as a non-GAAP financial measure. Adjusted net income (loss) represents net income (loss) excluding share-based compensation expenses. The Company's management believes that adjusted net income (loss) facilitates better understanding of operating results and provide management with a better capability to plan and forecast future periods. For more information on the non-GAAP financial measures, please see the table captioned "Reconciliation of GAAP and Non-GAAP Results" set forth at the end of this press release.
Non-GAAP information is not prepared in accordance with GAAP and may be different from non-GAAP methods of accounting and reporting used by other companies. The presentation of this additional information should not be considered a substitute for GAAP results. A limitation of using adjusted net income (loss) is that adjusted net income (loss) excludes share-based compensation expense that has been and may continue to be incurred in the future.
