AbstractAdult T-cell leukemia (ATL) is a lymphoid neoplasm caused by human T-cell leukemia virus type 1 (HTLV-1), which encodes the transcriptional activator Tax, which participates in the immortalization of infected T cells. ATL is classified into 4 subtypes: smoldering, chronic, acute, and lymphoma. We determined whether natural killer receptors (NKRs) were expressed in ATL. NKR expression (KIR2DL1/2DS1, KIR2DL2/2DL3/2DS2, KIR3DL2, NKG2A, NKG2C, and NKp46) was assessed in a discovery cohort of 21 ATL, and KIR3DL2 was then assessed in 71 patients with ATL. KIR3DL2 was the only NKR among those studied frequently expressed by acute-type vs lymphoma- and chronic/smoldering-type ATL (36 of 40, 4 of 16, and 1 of 15, respectively; P = .001), although acute- and lymphoma-type ATL had similar mutation profiles by targeted exome sequencing. The correlation of KIR3DL2 expression with promoter demethylation was determined by microarray-based DNA methylation profiling. To explore the role of HTLV-1, KIR3DL2 and TAX messenger RNA (mRNA) expression levels were assessed by PrimeFlow RNA in primary ATL and in CD4+ T cells infected with HTLV-1 in vitro. TAX mRNA and KIR3DL2 protein expressions were correlated on ATL cells. HTLV-1 infection triggered KIR3DL2 by CD4+ cells but Tax alone did not induce KIR3DL2 expression. Ex vivo, autologous, antibody-dependent cell cytotoxicity using lacutamab, a first-in-class anti-KIR3DL2 humanized antibody, selectively killed KIR3DL2+ primary ATL cells ex vivo. To conclude, KIR3DL2 expression is associated with acute-type ATL. Transcription of KIR3DL2 may be triggered by HTLV-1 infection and correlates with hypomethylation of the promoter. The benefit of targeting KIR3DL2 with lacutamab is being further explored in a randomized phase 2 study in peripheral T-cell lymphoma, including ATL (registered on https://clinicaltrials.gov as #NCT04984837).

New biotherapies for the treatment of cutaneous T-cell lymphomas

Q4 · MEDICINE

Review

Author: de Masson, A

Most cutaneous lymphomas are cutaneous T-cell lymphomas, and the most common form is mycosis fungoides. Sézary syndrome is a leukemic form of cutaneous T-cell lymphoma which is characterized by erythroderma and the presence of blood tumor cells. The only potential cure of cutaneous T-cell lymphomas remains allogeneic stem cell transplantation. However, monoclonal antibodies have led to a substantial progress in the treatment of advanced-stage cutaneous T-cell lymphomas. Some of them, such as mogamulizumab (anti-CCR4 monoclobal antibody) or brentuximab vedotin (anti-CD30 coupled to monomethylauristatin E, antibody drug conjugate) have shown efficacy in international randomized controlled studies. Lacutamab, an anti-KIR3DL2 monoclonal antibody, is currently tested in an international, prospective phase 2 trial in cutaneous T-cell lymphomas and peripheral T-cell lymphomas. Finally, immune checkpoint inhibitors have shown clinical benefit in open-label phase 2 studies in cutaneous T-cell lymphomas. This review focuses on the new biotherapies currently used in cutaneous T-cell lymphomas.

Investigative drugs for the treatment of cutaneous T-cell lymphomas (CTCL): an update

Q2 · MEDICINE

Review

Author: Guenova, Emmanuella ; Ramelyte, Egle ; Dummer, Reinhard

Introduction: Cutaneous T-cell lymphoma (CTCL) is a heterogeneous group of skin-homing T-cell neoplasms, which represent approximately 75% of all primary cutaneous lymphomas. Mycosis fungoides and Sézary syndrome are the most common CTCL. Early stage disease follows a protracted course, carries a 5-year disease specific survival of 97% and can be treated with skin-directed therapies. Widespread, advanced disease has a 5-year OS of less than 25% and necessitates systemic treatment. Allogeneic stem cell transplantation is a potentially curative treatment option for advanced CTCL, however, transplant-related morbidity and mortality must be considered and a risk-benefit assessment performed on individual basis. Areas covered: Herein, we provide a review of investigative drugs in early-stage trials for the treatment of cutaneous CTCL, including topically applied immunomodulators such as replicating herpes virus or toll-like receptor 7/8 agonist resiquimod and systemic therapies with monoclonal antibodies, such as anti-CD47, recombinant cytotoxic interleukin 2 fusion protein anti-KIR3DL2 antibody and anti-miR-155 antibody. Expert Opinion: Among the reviewed drugs, resiquimod shows promising clinical efficacy with good tolerability in early CTCL. In refractory or relapsed disease, intratumoral anti-CD47-, anti-CCR4- and anti-KIR3DL2-antibodies show high response rates, however, latter two also show considerable toxicity. Larger trials are needed to better evaluate the discussed therapies.

Request a sample and discover the recent advances in the NK cell therapy segment @ NK Cell Therapy Pipeline Report The NK cell therapy pipeline report provides detailed profiles of pipeline assets, a comparative analysis of clinical and non-clinical stage NK cell therapies, inactive and dormant assets, a comprehensive assessment of driving and restraining factors, and an assessment of opportunities and risks in the NK cell therapy clinical trial landscape. NK Cell Therapy Overview Natural Killer (NK) cell therapy is an innovative approach in immunotherapy that harnesses the power of NK cells, a vital component of the innate immune system. Unlike T cells, which require prior sensitization to target cancer cells, NK cells can recognize and kill abnormal cells without prior exposure. This unique ability makes NK cell therapy a promising option for treating various cancers, including hematologic malignancies like leukemia and lymphoma, as well as solid tumors. By isolating and activating NK cells from a patient's blood or using engineered NK cells from healthy donors, researchers aim to enhance the immune response against tumors, leading to improved patient outcomes. Recent advancements in genetic engineering, such as the introduction of chimeric antigen receptors (CAR) into NK cells, are further enhancing their specificity and efficacy against cancer cells. The clinical applications of NK cell therapy are expanding rapidly, supported by a growing body of research and early-phase clinical trials. These studies have shown promising results, demonstrating the ability of NK cell therapy to induce durable remissions in patients with refractory cancers. Furthermore, the off-the-shelf nature of certain NK cell therapies allows for quicker treatment deployment compared to traditional CAR-T cell therapies, which require a personalized approach. Challenges remain, including optimizing NK cell expansion, persistence, and overcoming the immunosuppressive tumor microenvironment. However, ongoing research into combination therapies, such as pairing NK cell therapy with checkpoint inhibitors or monoclonal antibodies, is expected to enhance the therapeutic potential of NK cells and provide new hope for cancer patients.
