A Phase III registrational study of orelabrutinib for the first-line treatment of MCD subtype diffuse large B-cell lymphoma (DLBCL) is ongoing in 45 sites in China.
Tafasitamab

Patient enrollment of the registrational trial of tafasitamab in combination with lenalidomide for the treatment of r/r DLBCL was completed in China. The Company expects to submit the biologics license application (BLA) in the second quarter of 2024 and anticipates BLA approval in the first half of 2025.
Tafasitamab in combination with lenalidomide was approved by the Department of Health, the Hong Kong Special Administrative Region, China, and approved for use in Bo’ao and Greater Bay Area with first prescription issued respectively.
ICP-248

The preliminary results demonstrated good safety profile and achieved favorable pharmacokinetic (PK), demonstrating differentiation from other BCL2 inhibitors. So far, seventeen patients were dosed, and among six evaluated patients, the ORR was 100%, with three complete responses (CR) in which two achieved undetectable minimal residual disease (uMRD).
The clinical trial approval of ICP-248 in combination with orelabrutinib as a first-line therapy for CLL/SLL in March 2024. In the U.S., the IND was cleared in January 2024. ICP-248 will become an important asset for the Company’s globalization.
ICP-248 is a novel, orally bioavailable BCL2 selective inhibitor, developed as monotherapy or in combination with orelabrutinib for the treatment of CLL/SLL, MCL, AML, and other NHLs.
ICP-B02 (CM355)

The preliminary data of both the intravenous infusion (IV) and the subcutaneous (SC) formulations have shown good efficacy of ICP-B02 in patients with follicular lymphoma (FL) and DLBCL. All 13 patients who were treated with ICP-B02 at doses ≥6mg achieved response, resulting in an ORR of 100%. Among the nine patients who were evaluable in the SC group, seven achieved a complete response (CR), including two with DLBCL.
Based on the encouraging results of ICP-B02 single agent, the Company is planning for dose expansion study of ICP-B02 in combination with other immunochemotherapies for earlier lines of treatment in NHL patients. An IND for the combination therapies has been submitted.
ICP-B02 is a CD20xCD3 bispecific antibody co-developed with Keymed.
ICP-490

The Phase I dose escalation study is ongoing in China with multiple myeloma (MM) patients, demonstrating a good tolerability and safety profile. Pharmacodynamic (PD) analysis showed deeper degradation of primary pharmacological targets Aiolos (IKZF3) and Ikaro (IKZF1).
In September 2023, the IND was approved to conduct a clinical trial of ICP-490 in combination with dexamethasone. ICP-490 shows strong potential in hemato-oncology therapeutics as a monotherapy or in combination with others.
ICP-490 was developed from InnoCare’s molecular glue platform for the treatment of MM and other hematological malignancies.
ICP-B05 (CM369)

The Phase I trial is ongoing, showing good tolerability with no DLT observed. The preliminary results demonstrate favorable PK profile and PD biomarker, Treg depletion, was observed.
Dose escalation in solid tumors has been escalated up to 150 mg, which is also the initial dose designated for NHL. Preliminary efficacy was observed in NHL.
ICP-B05 is an anti-CC chemokine receptor 8 (CCR8) monoclonal antibody, a potential first-in-class drug co-developed with KeyMed as a monotherapy or in combination with other therapies for the treatment of various cancers.
Developing B-cell and T-cell Pathways in Autoimmune Diseases

Autoimmune diseases can affect almost every organ in the body and can occur at any age. The global market for autoimmune disease therapeutics anticipated to reach $185 billion by 20291. The Company has fortified its powerful discovery engine focusing on global frontier targets for the development of differentiated autoimmune therapeutics through B-cell and T-cell pathways, aiming to offer first-in-class or best-in-class treatments to the massive unmet medical needs with promising market potential worldwide and/or regionally.

Orelabrutinib

ITP: The Company has achieved proof of concept (PoC) of orelabrutinib for the treatment of primary immune thrombocytopenia purpura (ITP), with a Phase III registrational trial underway in China. The last patient is expected to be enrolled by the end of 2024. In June 2023, the ITP Phase II result was orally presented at the European Hematology Association (EHA) (Free EHA Whitepaper) 2023 Hybrid Congress. The results showed that 40% of patients met primary endpoint at 50mg. 83.3% achieved durable response among patients met the primary endpoint. A subgroup analysis of patients who previously responded to glucocorticoids (GC) or intravenous immunoglobulin (IVIG) showed that 75.0% of patients at the 50mg dose achieved the primary endpoint.
SLE: The Phase IIa trial for systemic lupus erythematosus (SLE) demonstrated positive results, with remarkable SLE Responder Index (SRI)-4 response rates observed in a dose dependent manner, along with trends indicating a reduction in proteinuria levels. A Phase IIb trial is ongoing, and the Company expects to complete patient enrollment by mid-2024.
MS: The 24-week data of orelabrutinib from the multiple sclerosis (MS) global Phase II trial is consistent with the previous reported 12-week data in terms of both efficacy and safety.
The primary endpoint was achieved dose-dependently (Cmax driven) in all three active orelabrutinib treatment groups. Notably, a 92.3% relative reduction was achieved in cumulative number of new gadolinium (Gd) + T1 lesions at week 24 at 80mg QD compared to placebo arm (which switched to orelabrutinib 50mg QD after Week 12). This reduction stands out as a leading indicator of efficacy when compared to other MS therapies that are approved or in developmental stages.
All orelabrutinib groups achieved T1 new lesion control after 4 weeks of treatment, with effects sustained through 24 weeks. The 80 mg QD cohort showed the highest reduction rate of cumulative number of new lesions Gd+T1 lesions and the best for lesion control throughout 24 weeks, with the best safety profile, indicating orelabrutinib’s potential as a leading MS treatment.
NMOSD: The Phase II clinical trial for the treatment of neuromyelitis optica spectrum disorder (NMOSD) is ongoing in China.
ICP-332

The latest data of ICP-332 for the treatment of patients with moderate-to-severe atopic dermatitis (AD) has been released at the 2024 American Academy of Dermatology (AAD) Annual Meeting as a late-breaking oral presentation.
ICP-332 demonstrated an outstanding efficacy and safety profile. ICP-332 achieved multiple efficacy endpoints in the 80 mg QD and 120 mg QD dosing groups respectively, including the percentage change in Eczema Area and Severity Index (EASI) score from baseline, EASI 50, EASI 75, EASI 90 (improvement of at least 50%, 75% and 90% in EASI score from baseline), Investigator’s Global Assessment (IGA) 0/1 (score of 0 ‘clear’ or 1 ‘almost clear’) with >= 2 points improvement, and Pruritus Numerical Rating Scale (NRS) score from baseline, etc.
The mean percentage change from baseline of the EASI score reached 78.2% and 72.5% at the 80 mg QD and 120 mg QD groups respectively, both with a highly significant P value (p<0.0001), compared to 16.7% for the patients receiving placebo. The percentages of patients achieving at least 75% improvement in EASI 75 were significantly higher in the ICP-332 80 mg QD (64.0%, p<0.0001) and 120 mg QD (64.0%, p<0.0001) groups than that of placebo (8.0%), which are better than the reported efficacies of multiple approved innovative drugs treated for 12 weeks or 16 weeks (not a head-to-head comparison).
In the ICP-332 80 mg QD group, the response rates of EASI 90 and IGA 0/1 with >=2 points from baseline demonstrated a 40.0% (P=0.0009) and 32.0% (P=0.0047) improvement respectively compared with the placebo group.
ICP-332 was safe and well tolerated in AD patients. The overall incidence rates of adverse events (AEs) and AEs related to infections and infestations in the two treatment groups were comparable to that of the placebo group.
The Company expects to start the patient enrollment of the Phase III trial for AD in China, initiate US trials, and initiate a Phase II trial for a second indication of vitiligo in 2024.
ICP-332 is a novel tyrosine kinase 2 (TYK2) inhibitor that is being developed for the treatment of various T-cell related autoimmune disorders.
ICP-488

The Phase I trial has been completed, with preliminary efficacy assessed in psoriasis patients. The least-squares mean percentage change from baseline in the Psoriasis Area and Severity Index (PASI) score indicated preliminary significantly difference between the ICP-488 6 mg once-daily dosing group and placebo group at week 4 (38% vs 14%, p=0.0870). PASI 50 assessments demonstrated a 42% improvement with treatment of ICP-488 at 6 mg QD.
Following single ascending doses (1mg to 36mg) and multiple ascending doses (3mg -12mg) once daily, ICP-488 plasma exposures were dose proportional. No significant food effect was observed following co-administration with standard high-fat, high-calorie meals.
ICP-488 demonstrated good tolerability and safety. The TRAE rate was the same between the ICP-488 arm and placebo arm.
The Phase II study of psoriasis is ongoing, InnoCare targets to finish the patient enrollment in the first half of 2024.
ICP-488 is a potent and selective TYK2 allosteric inhibitor that binds to the pseudo kinase JH2 domain of TYK2 and blocks IL-23, IL12, type 1 IFN, and other cytokine receptors.
ICP-B02 (CM355)

ICP-B02 (SC & IV) induced a profound and sustained depletion of peripheral B- cells after first infusion in Phase I/II clinical trial in r/r NHL patients. Given the critical role of B-cells in a variety of severe autoimmune diseases, ICP-B02 may have wider applications in severe autoimmune diseases.
ICP-923 (New Target)

IL-17 is a pro-inflammatory cytokine that plays an important role in immune functional responses. Orally administered small molecules targeting IL-17 may represent a convenient alternative to IL-17-targeting monoclonal antibodies for patients. This novel orally available small molecule can potently block the binding of both IL-17AA and IL-17AF to IL-17R.
Building Innovative Solid Tumor Assets

InnoCare strives to expand the breadth of its pipeline to cover solid tumor diseases areas through a combination of targeted therapy and immune-oncology approaches. The Company believes that potential best-in-class molecule, zurletrectinib (ICP-723), will enable InnoCare to establish a solid footprint in the field of solid tumor treatment. To benefit a broader range of patients, InnoCare’s rapidly maturing early-stage pipeline, including the cornerstone therapy ICP-192, ICP-189 and ICP-B05 immune-oncology treatment, aims to offer competitive treatment solutions for a large array of solid tumors, both in China and worldwide.

Zurletrectinib (ICP-723)

InnoCare is accelerating the registrational trial of zurletrectinib in China. The NDA is expected to be submitted by the end of 2024.
An outstanding efficacy of 80-90% ORR was observed in adult patients with various cancers carrying NTRK gene fusion who received ≥8 mg dosages.
Zurletrectinib was shown to overcome acquired resistance to the first generation TRK inhibitors, bringing hope for patients who failed prior TRKi therapy.
The Company is conducting a clinical trial of zurletrectinib for pediatric (2 to 12 years old) and adolescent patients (12 to 18 years old). Patient enrollment of pediatric patients is ongoing, with PR observed.
ICP-189

InnoCare and ArriVent reached a clinical development collaboration to evaluate the anti-tumor activity and safety of the combination of InnoCare’s novel SHP2 allosteric inhibitor, ICP-189, with ArriVent’s third generation EGFR inhibitor furmonertinib in patients with advanced non-small cell lung cancer (NSCLC). Currently, the combo study is underway. NSCLC is the predominant subtype of lung cancer, accounting for approximately 85% of all cases2.
The novel SHP2 allosteric inhibitor, ICP-189, is being developed for the treatment of solid tumors as a single agent and/or in combination with other antitumor agents. Preliminary efficacy was observed in ICP-189 monotherapy. As of this announcement, the dosage has been escalated up to 120 mg with no DLT observed, and it has shown a favorable PK profile with a long half-life. The patient enrollment at 160mg QD is ongoing.
As a potential first-in-class SHP2 inhibitor, ICP-189 is an ideal partner for combination with multiple targeted and immune-oncology therapies in solid tumors. ICP-189 has demonstrated significant anti-tumor effect in tumor models driven by KRASG12C mutation and EGFR over-expression.
Gunagratinib (ICP-192)

The latest data of gunagratinib in patients with cholangiocarcinoma (CCA) was presented at 2023 ASCO (Free ASCO Whitepaper)-GI3. Gunagratinib showed good efficacy and safety in previously treated patients with locally advanced or metastatic CCA harboring FGR2 gene fusions or rearrangements.
Other Corporate Development

InnoCare appointed Xin Fu and Jeff Chen as Chief Financial Officer and Chief Commercial Officer respectively.
InnoCare was approved by the Hong Kong Stock Exchange to remove "B" from the stock code from May 12, 2023. This is another important milestone in the Company’s development.

"The significant majority of KRAS-, NRAS-, and BRAF-mutant tumors are not addressable by currently approved therapies, creating a pressing need for new medicines that provide superior, durable efficacy and tolerability for people living with these hard-to-treat cancers," said Philip Komarnitsky, M.D., Ph.D., chief medical officer of Nested. "We believe that NST-628 has the potential to provide a differentiated clinical profile, including a superior therapeutic index and prevention of pathway reactivation, for patients with advanced solid tumors harboring RAS-MAPK pathway alterations. The IND clearance for NST-628 is an important step in the advancement of our first clinical-stage program, and with clinical trial sites already activated, we look forward to dosing the first patients in this trial in the first half of this year."

The Phase 1 open-label, single-arm, two-part study (NCT06326411) is intended to investigate the safety, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary efficacy of single agent NST-628 in adult patients with RAS-MAPK pathway mutated/dependent advanced solid tumors who have exhausted standard treatment options. The study includes two parts: dose escalation (Part A) followed by dose expansion (Part B). The primary objectives for Part A are delineating NST-628’s safety profile and establishing the recommended dose for Part B. For more information, visit clinicaltrials.gov.

About NST-628
NST-628 is a fully brain-penetrant, mechanistically novel non-degrading molecular glue that targets multiple nodes in the RAS/MAPK pathway. NST-628 was developed based on Nested’s proprietary structural insights of how signaling complexes form and function in cancer and addresses common pitfalls of other MAPK-targeted compounds, which remain unable to circumvent the risk of resistance via signaling pathway reactivation. Preclinical data evaluating all biomarkers relevant to RAS/MAPK-driven cell and patient-derived models collectively demonstrate superior anti-tumor activity, including in RAS and central nervous system-implanted tumor models, and tolerability of NST-628 compared to other MAPK-targeted compounds administered as either single agents or in combination. With a half-life and metabolic profile optimized to achieve a superior therapeutic index on a daily dosing schedule, as well as full intrinsic blood brain barrier penetrance, these data support NST-628’s potential as a best-in-class treatment for RAS and RAF-driven cancers.
