The U.S. Food and Drug Administration (FDA) has recently approved several innovative therapies that are transforming the treatment landscape for hematologic cancers. These approvals signify major advancements in targeted therapies, monoclonal antibodies, and immune checkpoint inhibitors, offering new hope for patients battling these diseases.
Monoclonal Antibodies: Precision Targeting in Hematologic Cancers
Monoclonal antibodies (mAbs) have become a cornerstone in the treatment of blood cancers due to their ability to precisely target cancer cells. One notable approval is glofitamab (Columvi), which received accelerated approval in June 2023 for relapsed or refractory diffuse large B-cell lymphoma (DLBCL). This bispecific antibody targets both CD20 on B-cells and CD3 on T-cells, effectively redirecting T-cells to kill cancer cells (ASCOPost) (Targeted Oncology).
Another significant mAb is epcoritamab (Epkinly), approved in May 2023 for relapsed or refractory DLBCL. Epcoritamab is a subcutaneously administered bispecific antibody that binds to CD3 and CD20, engaging T-cells to attack B-cell lymphomas (ASCOPost) (FDA).
Targeted Therapies: Focused Treatment for Better Outcomes
Targeted therapies specifically address the molecular abnormalities driving cancer growth. Quizartinib (Vanflyta), approved in July 2023, is a FLT3 inhibitor used in combination with chemotherapy for newly diagnosed acute myeloid leukemia (AML) with FLT3-ITD mutations. This approval is based on its ability to significantly improve overall survival rates in patients (Targeted Oncology) (FDA).
Pirtobrutinib (Jaypirca), another targeted therapy, was approved in January 2023 for relapsed or refractory mantle cell lymphoma after at least two prior treatments, including a BTK inhibitor. Pirtobrutinib’s approval is a testament to its efficacy in targeting the BTK pathway, which is crucial for the survival and proliferation of malignant B-cells (ASCOPost).
Immune Checkpoint Inhibitors: Enhancing the Immune Response
Immune checkpoint inhibitors work by unleashing the body’s immune system to attack cancer cells. Dostarlimab (Jemperli), approved in April 2023, is an anti-PD-1 antibody used for patients with mismatch repair-deficient (dMMR) endometrial cancer. Although primarily for solid tumors, this approval underscores the expanding role of checkpoint inhibitors in various cancers, including hematologic malignancies (OncLive).
Talquetamab (Talvey), approved in August 2023, is a first-in-class bispecific antibody targeting GPRC5D and CD3, used for relapsed or refractory multiple myeloma after at least four prior therapies. This novel approach highlights the ongoing innovation in immunotherapy for blood cancers (Targeted Oncology).

Future Implications for Hematologic Oncology
The recent FDA approvals of these therapies not only provide new treatment options but also pave the way for future innovations. The integration of monoclonal antibodies, targeted therapies, and immune checkpoint inhibitors into treatment regimens represents a significant shift towards more personalized and effective cancer care. These advancements are expected to improve survival rates and quality of life for patients with hematologic malignancies.
The continued research and development in this field promise even more breakthroughs, with numerous therapies currently in clinical trials. As our understanding of cancer biology deepens, the development of highly specific and effective treatments will likely accelerate, bringing new hope to patients and their families.
