ROCKVILLE, MD, U.S.(US) and SHANGHAI, China, August 17, 2023 – I-Mab (Nasdaq: IMAB) (the “Company”), is a global biotechnology company focused on bringing highly differentiated medicines to patients around the world through the discovery, development, and commercialization of novel immunotherapies and biologics for oncology, today announced its financial results for the six months ended June 30, 2023, and provided key business updates.

I-Mab has made significant progress in advancing its pipeline of innovative assets over the last eight months.

“2023 is off to a great start with promising early results from our two lead oncology programs, uliledlimab, and givastomig, coupled with new, positive Phase 3 eftansomatropin alfa results, thanks to the diligent efforts of our employees. As we move forward, we plan to focus on three strategic pillars: prioritizing two promising clinical assets in oncology to advance in the US, maintaining our strong balance sheet, and focusing on establishing a new operating model to become a US-based global biotech company,” said Raj Kannan, Chief Executive Officer of I-Mab.

H1 2023 Key ClinicalProgram Highlights

Uliledlimab (CD73 mAb): Encouraging clinicaland translational data presented at ASCO 2023

Uliledlimab is a highly differentiated CD73 antibody which can completely inhibit CD73 enzymatic activity without causing the aberrant pharmacological property known as the “hook effect.” Results from an ongoing Phase 2 study of uliledlimab in combination with toripalimab, a PD-1 inhibitor, showed a favorable safety profile and an encouraging objective response rate (ORR) of 31% (21/67) in the overall population regardless of CD73 and PD-L1 expression. In this study, without concomitant chemotherapy, in patients whose tumors expressed higher levels of CD73 and had a PD-L1 tumor proportion score (TPS) of >1%, the observed ORR was 63% (10/16).

Next steps: The clinical program is currently focused on non-small cell lung cancer (NSCLC) and ovarian cancer. Enrollment in the Phase 2 study of uliledlimab with toripalimab for patients with ovarian cancer is ongoing in China. In the US, I-Mab plans to submit an IND for uliledlimab in combination with chemotherapy and checkpoint inhibitors in newly diagnosed patients with advanced NSCLC in H1 2024.

Givastomig (Claudin 18.2 x 4-1BB bispecific Ab): Phase 1 trial dataand publication highlight potential for a differentiated program

Encouraging initial Phase 1 results: Givastomig was designed as a bispecific antibody to target Claudin 18.2-positive tumor cells and stimulate pro-immune 4-1BB signaling. Phase 1 dose escalation has reached the highest planned dose level. Most treatment-related adverse events have been low-grade. In this study, encouraging findings of monotherapy efficacy were observed, including in tumors with lower levels of Claudin 18.2 expression, in patients with previously treated cancer that has relapsed or progressed after prior standard treatments.

Preclinical data on this program were published in the July 2023 issue of the Journal of Immunotherapy of Cancer, and the Phase 1 monotherapy dose escalation data were selected for presentation at the European Society of Medical Oncology (ESMO) in October 2023. An expansion cohort of patients with Claudin 18.2 positive gastric, gastroesophageal junction (GEJ), and esophageal cancer whose disease has progressed after previous treatment is enrolling, and interim results are expected in H1 2024.

Based upon these encouraging signals, dose escalation is expected to begin in combination with standard chemotherapy and immunotherapy regimens for patients with treatment naïve gastric, GEJ, and esophageal cancer in the US, Japan, and China in H1 2024.

The program is being developed in collaboration with ABL Bio.

TJ-L14B/ABL503 (PD-L1 x 4-1BB bispecific antibody):Phase 1 Dose Expansion initiated in H1 2023

TJ-L14B/ABL503 was designed to treat PD-(L)1 antibody-resistant tumors. The antibody acts by inducing conditional activation of 4-1BB when it binds to its target, PD-L1. A Phase 1 dose-escalation study is underway in patients with progressive, locally advanced or metastatic solid tumors who are relapsed or refractory following prior lines of treatment. A preliminary efficacy signal has been observed, and a maximally tolerated dose (MTD) has not yet been reached. The dose expansion portion of the Phase 1 study is underway in the US and South Korea. The program is also being developed in collaboration with ABL Bio.

New Data: Eftansomatropin alfa (long-actingrecombinant human growth hormone)

I-Mab today announced positive topline results from its multi-center, randomized, open-label, active-controlled pivotal phase 3 study (CTJ101PGHD301) evaluating the efficacy and safety of eftansomatropin alfa in children with growth hormone deficiency.

The study met its primary endpoint of annualized height velocity (AHV) at week 52 and demonstrated that eftansomatropin alfa was non-inferior to Norditropin®. Eftansomatropin alfa was given by weekly injection vs. Norditropin® given by daily injection. The mean AHV was 10.76 (cm/year) for eftansomatropin alfa vs. 10.28 (cm/year) for Norditropin®, with a difference of 0.47 [95% CI -0.06,1.00] and non-inferiority p-value <0.0001. Eftansomatropin alfa was well tolerated and no drug discontinuation was reported due to treatment related adverse events. The safety profile of eftansomatropin alfa was comparable to Norditropin®. The Company is planning to file a BLA submission in China in 2024.

Commercial partnership with Jumpcan for product launch and commercialization of eftansomatropin alfa in China is ongoing.

Felzartamab (CD38 antibody): Phase 3 MultipleMyeloma Results Expected in 2024

Felzartamab is in development for the treatment of multiple myeloma (MM). Clinical studies have been conducted in second- and third-line treatment settings. The randomized, open-label, parallel-controlled Phase 3 study of felzartamab in combination with lenalidomide and dexamethasone as a second-line treatment for MM with progression-free survival (PFS) as the primary endpoint is ongoing with a projected read-out in 2024, followed by planned BLA submission.

Lemzoparlimab (CD47 antibody): Phase 3 trial underway in China


The development of lemzoparlimab, focused on China, has the potential to be the first-in-class CD47 antibody for hematologic malignancies in this market. The Phase 3 program is evaluating lemzoparlimab in combination with azacytidine (AZA) as first-line treatment for patients with newly diagnosed higher-risk myelodysplastic syndrome (MDS). Enrollment in the Phase 3 trial was initiated in April 2023. The Company will continue to review Phase 2 clinical follow-up data in the higher risk-MDS study and analyze details from other trials evaluating other CD47-targeting agents as they are released, to inform the Company’s decisions on the future steps for the program.

Corporate Development

· In August 2023, the Board<br>of Directors of the Company authorized a new share repurchase program under which the Company may repurchase up to US$40 million of American<br>depository shares (“ADSs”) or ordinary shares in aggregate over the next 12 months. The timing and dollar amount of share<br>repurchase transactions will be subject to the applicable U.S. Securities and Exchange Commission rule requirements. The Company’s<br>Board of Directors will review the implementation of share repurchases periodically and may authorize adjustment of its terms and size.
· Proprietary position for uliledlimab<br>fortified with Tracon and KG Bio resolutions.
--- ---
- The positive outcome in arbitration relating to the collaboration agreement with Tracon Pharmaceuticals, Inc.<br>(Tracon) confirms that Tracon has no rights to share any future economics with I-Mab for uliledlimab.
--- ---
- In June 2023, the Company terminated the first negotiation agreement with Kalbe Genexine Biologics<br>(KG Bio), pursuant to which KG Bio no longer has a right of first negotiation for the exclusive right to commercialize uliledlimab in<br>Southeast Asia and other territories.

Use of Non-GAAP FinancialMeasures

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) before share-based compensation. The Company’s management believes that adjusted net income (loss) facilitates an understanding of operating results and provides 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.
