When the "quality control" system of this factory malfunctions, hematologic malignancies can arise—malignant diseases originating from hematopoietic cells that can affect the bone marrow, blood, and various organs and tissues throughout the body. Clinically common hematologic malignancies primarily include various types of leukemia, multiple myeloma, lymphoma, myelodysplastic syndromes, and myeloproliferative neoplasms. Their incidence and mortality rates rank high, making them significant diseases that seriously endanger human health. Among hematologic tumors, the most prevalent in terms of case numbers are leukemia, multiple myeloma, and lymphoma. Leukemia accounts for approximately 36% of hematologic tumors, multiple myeloma for about 13%, and lymphoma for about 51%. The global combined incidence rate of these three hematologic tumors exceeds 13 per 100,000 people (Figure 1). ▲ Figure 1. Overview of Hematologic Malignancies   With the continuous emergence of innovative therapies, the drug market for hematologic tumors continues to expand. Among these, macromolecular drugs and CAR-T have become important treatment modalities. Current "standout" products in the hematologic tumor macromolecular drug market include CD38 monoclonal antibodies with global sales exceeding $10 billion in 2024, as well as CAR-T therapies and bispecific antibodies showing strong performance growth in 2025. These innovative therapies represent key future growth drivers for the market. 01 Acute Myeloid Leukemia: A New Era of Precision Stratified Treatment Acute Myeloid Leukemia (AML) is the most common acute leukemia in adults, characterized by the abnormal proliferation and blocked differentiation of immature myeloid cells in the bone marrow, leading to failure of normal hematopoiesis. This disease exhibits high genetic heterogeneity, and its pathogenesis involves various genetic alterations, including chromosomal translocations, gene mutations, and epigenetic abnormalities. These molecular aberrations collectively disrupt fundamental cellular processes like proliferation, differentiation, and apoptosis, ultimately leading to the development of leukemia. 01 Clinical Management of AML For patients eligible for intensive chemotherapy, the "7+3" regimen (anthracycline + cytarabine) serves as the cornerstone. For those with FLT3 mutations, the addition of Midostaurin to this backbone has become the standard of care. For patients unsuitable for intensive chemotherapy, the combination of Venetoclax with Azacitidine or Decitabine is a widely used new standard. After first-line treatment failure or upon relapse, targeted agents form the core of second-line therapy. For instance, Gilteritinib can be chosen for FLT3 mutations, and Enasidenib can be used for IDH2 mutations. In the realm of immunotherapy, currently approved drugs are relatively few. Gemtuzumab Ozogamicin is an antibody-drug conjugate (ADC) targeting CD33, approved overseas for treating CD33-positive AML and accessible in China through the clinical urgent drug importation pathway. ▲ Figure 2. Schematic diagram of targeted therapeutic drugs and their mechanisms of action in Acute Myeloid Leukemia   02 Investigational Targets and Emerging Therapies in AML   In the field of AML targeted therapy, established targets have demonstrated solid clinical value, while emerging targets and therapies continue to expand the treatment landscape. Among the mature targets:  ▷1) FLT3 is a core one, with Gilteritinib established as a standard option for relapsed/refractory FLT3-mutated AML. The novel FLT3/CHK1 dual-target inhibitor TLX-83 specifically addresses the challenge of resistance, offering new hope for patients.  ▷2) CD33 has secured its place in the clinic with the ADC drug Gemtuzumab ozogamicin.  ▷3) Menin inhibitors (e.g., Ziftomenib) targeting NPM1 mutations or KMT2A rearrangements have received FDA Breakthrough Therapy designation, achieving deep responses in relapsed/refractory patients and highlighting the potential of precision medicine. From a global perspective of target research popularity, CD33 leads with 103 active studies, and FLT3 also has 26 research programs, underscoring their central role in the R&D landscape. The continued in-depth research and iterative innovation of drugs against these established targets are building a solid line of defense for AML patients. Concurrently, emerging therapeutic approaches are reshaping the AML treatment paradigm through multi-dimensional innovation.  ▷1) In the cellular immunotherapy domain, dual-target CAR-NK therapies targeting both CD33 and MSLN, combined with gene-editing technology to avoid "fratricide," significantly enhance the durability of efficacy, opening new pathways for cell therapy.  ▷2) In the bispecific antibody field, T-cell engagers targeting antigens like CD33, CD123, FLT3, and CLEC12A are in various stages of investigation, promising enhanced anti-tumor activity through multi-target synergy. Furthermore, the distribution of target research indicates that other targets like CD47 and CD70 are also advancing rapidly. These emerging directions not only enrich the AML treatment "arsenal" but also hold the potential to break through current therapeutic bottlenecks, offering patients improved survival benefits. This highlights the vibrant innovative activity and broad prospects within the AML targeted therapy field. ▲ Figure 3. Progress of TOP 20 Investigational Biological Drug Targets in Acute Myeloid Leukemia (Antibody-based, Conjugated Drugs, Cell Therapy)   02 Multiple Myeloma: Breakthroughs Led by Immunotherapy Multiple Myeloma (MM) is the second most common hematologic malignancy after non-Hodgkin lymphoma, characterized by the malignant proliferation of plasma cells in the bone marrow, accompanied by the overproduction of a monoclonal immunoglobulin (M protein). The disease is highly heterogeneous and can be classified into various subtypes such as IgG, IgA, and IgD types based on the M protein isotype. 01 Clinical Management of Multiple Myeloma In the first-line treatment of Multiple Myeloma (MM), patients eligible for autologous stem cell transplantation (ASCT) receive the D-VRd regimen (Daratumumab + Bortezomib + Lenalidomide + Dexamethasone). For transplant-ineligible patients, the D-VMP regimen (Daratumumab + Bortezomib + Melphalan + Prednisone) or the Isa-VRd regimen (Isatuximab + VRd) are chosen. Second-line therapy for patients refractory to CD38 monoclonal antibodies may include BCMA-targeted CAR-T therapies (e.g., Ide-cel, Cilta-cel), the ADC drug Belantamab mafodotin in combination regimens, or Pomalidomide-based regimens (e.g., combined with Elotuzumab and Dexamethasone for those refractory to Lenalidomide). Third-line therapy focuses on "triple-class refractory" patients, where innovative therapies such as bispecific antibodies (e.g., the BCMAxCD3 bispecific Bictegravir, bispecifics targeting GPRC5D), CAR-T therapies (Ide-cel, Cilta-cel), and the nuclear export inhibitor Selinexor become crucial options. ▲ Figure 4. Schematic diagram of targeted therapeutic drugs and their mechanisms of action in Multiple Myeloma 02 Investigational Targets and Emerging Therapies in MM In the field of Multiple Myeloma (MM) targeted therapy, BCMA ranks first globally in research popularity with 296 studies, establishing itself as a mature and highly promising core target.  ▷1) Among these, the BCMA/CD3 bispecific antibody Bictegravir has been approved for third-line use, and its ADC counterpart Blenrep is also approved in the EU in combination regimens.  ▷2) The CD38 target has 93 active studies; Daratumumab and Elotuzumab have provided significant patient benefit, particularly offering new options for patients refractory to CD38 monoclonal antibodies. ▷3) Research on the GPRC5D target follows closely in popularity, with its specific bispecific antibody Talquetamab demonstrating an objective response rate exceeding 70%, emerging as a new highlight in targeted therapy.  ▷4) The recently targeted FcRH5 antigen, with its bispecific antibody Cevostamab achieving an 88% objective response rate in Phase I trials, shows potential to overcome BCMA resistance due to its expression on nearly all myeloma cells. Plans are underway to proceed directly to Phase III clinical trials. The vigorous research and drug approvals surrounding these targets are constructing a precision treatment matrix for MM patients from first to later lines of therapy. Simultaneously, emerging therapeutic strategies are continuously pushing the boundaries of treatment through multi-target innovation and combination approaches.  ▷1) For example, Johnson & Johnson's trispecific antibody JNJ-79635322, targeting BCMA, GPRC5D, and CD3 simultaneously, achieved a high 86% objective response rate at the recommended Phase II dose in Phase I studies.  ▷2) Domestic pharmaceutical companies are also accelerating their pipelines; for instance, Wuhan YZY Biopharma's bispecific antibody Y150 (targeting CD38 and CD3) has completed Phase I clinical trials. The development of these multi-target antibody drugs not only enriches the MM treatment "arsenal" but also enhances efficacy and overcomes resistance through synergistic effects, demonstrating the dynamic innovation and broad application prospects in the MM targeted therapy landscape, bringing more hope for survival to patients. ▲ Figure 5. Progress of TOP 20 Investigational Biological Drug Targets in Multiple Myeloma (Antibody-based, Conjugated Drugs, Cell Therapy) 03 Lymphoma: Personalized Therapy for a Heterogeneous Disease Lymphoma represents a group of highly heterogeneous hematologic malignancies whose treatment strategies heavily rely on precise pathological classification and molecular profiling. Current authoritative international treatment guidelines (including NCCN, ESMO, and CSCO) all emphasize individualized treatment based on disease subtype, stage, and molecular markers.   01 Clinical Management of Lymphoma In lymphoma treatment, first-line therapy is cornerstoneed by the R-CHOP immunochemotherapy regimen. For patients with diffuse large B-cell lymphoma harboring MyD88 L265p or CD79B mutations, exploration of combining the BTK inhibitor Zanubrutinib is underway to improve efficacy. Second-line therapy centers on targeted agents. BTK inhibitors are widely used, and novel approaches like a "novel delivery system loading si-BTK and Isoimperatorin (ISOIM)" are being explored. For rare types like primary effusion lymphoma, PI3K/mTOR dual-target inhibitors (e.g., BGT226/Dactolisib) show new potential. Third-line treatment relies on drugs with innovative mechanisms, such as novel PI3Kδ/HDAC6 dual-target inhibitors (lead compound 22E) and highly selective PI3Kδ inhibitors (TYM-3-98). ▲ Figure 6. Lymphoma Signal Transduction Pathways and Targeted Drugs   02 Investigational Targets and Emerging Therapies in Lymphoma In the field of lymphoma targeted therapy, research on classic targets like CD19, CD20, and CD22 has entered a new stage. The CAR-T therapy Reni Orelen Syringe Solution (恒凯莱®, HR001) has demonstrated durable responses in relapsed/refractory large B-cell lymphoma (with 3-month and 6-month objective response rates (ORR) of 53.1% and 45.7%, respectively). Meanwhile, CD20×CD3 bispecific antibodies are pioneering new paths in immunotherapy by mediating T cell-dependent cytotoxicity. In the Chinese market, Roche's Mosunetuzumab (trade name: 皓罗华®) and Glofitamab have been approved for treating different types of lymphoma. Concurrently, emerging targets and therapeutic modalities are rapidly advancing to overcome treatment bottlenecks.  ▷1) CD30 CAR-T therapy (e.g., Wuhan Borui Biotechnology's BRD-01) has shown significant efficacy and a favorable safety profile in clinical trials for relapsed/refractory Hodgkin Lymphoma. Development of drugs targeting the CD40/CD40L pathway is also progressing actively. Agonist antibodies (e.g., Mitazalimab) aim to activate the immune system against solid tumors, while antagonist antibodies (e.g., Frexalimab) show potential in autoimmune diseases like multiple sclerosis by inhibiting this pathway. Furthermore, novel cell therapies targeting Epstein-Barr virus (EBV) specific antigens (e.g., gp350) provide new research directions for treating EBV-associated lymphomas.  ▷2) Combination strategies employing bispecific antibodies and ADCs have shown marked success. A Phase III study confirmed that combining the CD20×CD3 bispecific antibody Mosunetuzumab with the CD79b ADC drug Polatuzumab Vedotin nearly tripled the median progression-free survival of patients.  ▷3) Next-generation "Armored CAR-T" cells, designed to secrete cytokines like IL-18 to modify the tumor microenvironment, significantly enhance the durability of responses. These multi-dimensional innovative explorations not only enrich the lymphoma treatment "arsenal" but also, through synergistic effects and mechanistic innovations, offer patients greater hope for survival, highlighting the vigorous innovative activity and broad application prospects in the lymphoma targeted therapy field. ▲ Figure 7. Progress of TOP 20 Investigational Biological Drug Targets in Lymphoma (Antibody-based, Conjugated Drugs, Cell Therapy) 04 Summary The treatment of hematologic malignancies will continue to advance through target innovation and technological iteration. Novel targets like FLT3/CHK1 dual inhibitors and FcRH5 aim to 破解 overcome resistance challenges. Innovative therapies such as multispecific antibodies and "Armored CAR-T" further enhance efficacy and safety through multi-mechanistic synergy. With the deepening integration of precision targeting and immunotherapy, the boundaries of curability for hematologic tumors are continually expanding, injecting powerful momentum into the innovative development of the antibody and biologics field. ▶ References: (Sant M, Allemani C, Tereanu C, et al.
