Abstract
Classic Hodgkin lymphoma (cHL) accounts for more than 90% of HL in developed countries. Although the current combined modality therapy make it have a high cure rate, the prognosis for heavily pretreated patients with relapsed or refractory (R/R) cHL remains poor. A novel antibody-drug conjugate (ADC), named camidanlumab tesirine (ADCT-301, Cami), is currently being evaluated for its efficacy and safety in R/R cHL. The primary objective of this review is to examine the current pharmacological properties of camidanlumab tesirine as well as its clinical antitumor activity and safety. Camidanlumab tesirine comprises a human IgG1 anti-CD25 monoclonal antibody HuMax®-TAC, conjugated to a pyrrolobenzodiazepine dimer toxin. Once it bound to CD25-expressing cells, camidanlumab tesirine is internalized by cells and delivers SG3199, then SG3199 irreversibly binds to DNA and forms DNA interstrand crosslinks, ultimately leading to cell death. In the phase 1 study, patients with R/R cHL who received camidanlumab tesirine had an overall response rate (ORR) of 71% and a complete response rate (CRR) of 42%. Additionally, the recommended doses provided in R/R cHL were determined to be 30 and 45 μg/kg. The pivotal phase 2 trial showed significant antitumor activity of camidanlumab tesirine in heavily pretreated R/R cHL patients who failed brentuximab vedotin and programmed death-1 blockade: ORR was 70.1% and CRR was 33.3%, and the median duration of response was 13.7 months. Adverse events such as fatigue, maculopapular rash, and anemia were frequently observed following administration of camidanlumab tesirine. Moreover, camidanlumab tesirine may cause Guillain-Barré syndrome or polyradiculopathy.

[PMID: 36634275 DOI: 10.1016/j.hemonc.2021.07.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 05/28/2021] [Accepted: 07/10/2021] [Indexed: 01/18/2023] Open
Abstract
Relapsed or refractory lymphoma is commonly treated with combination chemoimmunotherapy and cellular immunotherapy. Modest response rates and associated toxicities are obstacles to achieving durable remission using traditional cytotoxic chemotherapy, especially in frail patients with advanced disease. Antibody drug conjugates represent a new class of novel targeted agents with significant improvement in therapeutic efficacy in the treatment of lymphomas. Several of these agents, which offer improved targeting, greater potency, and better therapeutic index over traditional chemotherapy, are changing the treatment landscape for lymphomas and other hematological malignancies. Despite the therapeutic potential of these agents, the delivery and release of cytotoxic agents to malignant cells through the combination of a monoclonal antibody, payload, and linker represents a complex design challenge. This article reviews the clinical data on currently available antibody drug conjugates and the ongoing development of novel antibody drug conjugates. Antibody drug conjugates constitute an important armamentarium for treatment of lymphomas and their evolving roles in the treatment spectrum are discussed.

Abstract
Hodgkin lymphoma is a highly curable disease. Although most patients achieve complete response following frontline therapy, key unmet clinical needs remain including relapsed/refractory disease, treatment-related morbidity, impaired quality of life and poor outcome in patients older than 60 years. The incorporation of novel therapies, including check point inhibitors and antibody-drug conjugates, into the frontline setting, sequential approaches, and further individualized treatment intensity may address these needs. We summarize the current treatment options for patients with classical Hodgkin lymphoma from frontline therapy to allogeneic hematopoietic stem cell transplantation and describe novel trials in the field.

Abstract
BACKGROUND Novel approaches are required to improve outcomes in relapsed or refractory classical Hodgkin lymphoma and non-Hodgkin lymphoma. We aimed to evaluate camidanlumab tesirine, an anti-CD25 antibody-drug conjugate, in this patient population. METHODS This was a phase 1, dose-escalation (part 1), dose-expansion (part 2), multicentre trial done in 12 hospital sites (seven in the USA and five in the UK). Adults (≥18 years old) with pathologically confirmed relapsed or refractory classical Hodgkin lymphoma or non-Hodgkin lymphoma, an Eastern Cooperative Oncology Group performance status 0-2, who had no therapies available to them with established clinical benefit for their disease stage were enrolled. Camidanlumab tesirine was administered intravenously (3-150 μg/kg) once every 3 weeks. Primary objectives were to assess dose-limiting toxicity, determine maximum tolerated dose and recommended expansion dose(s), and assess safety of camidanlumab tesirine. Safety was assessed in all treated patients; antitumour activity was assessed in patients with one or more valid baseline and post-baseline disease assessment and in those who had disease progression or died after first study-drug dose. This trial was registered with ClinicalTrials.gov, NCT02432235. FINDINGS Between Oct 5, 2015, and Jun 30, 2019, 133 patients were enrolled (77 [58%] had classical Hodgkin lymphoma and 56 (42%) had non-Hodgkin lymphoma). Median follow-up was 9·2 months (IQR 4·2-14·3). Eight dose-limiting toxicities were reported in five (6%) of 86 patients who were evaluable; the maximum tolerated dose was not reached. The recommended doses for expansion were 30 μg/kg and 45 μg/kg for patients with classical Hodgkin lymphoma and 80 μg/kg for patients with T-cell non-Hodgkin lymphomas. No recommended doses for expansion were defined for B-cell non-Hodgkin lymphomas. Grade 3 or worse treatment-emergent adverse events (reported by ≥10% of the 133 patients) included increased γ-glutamyltransferase (20 [15%] patients), maculopapular rash (16 [12%]), and anaemia (15 [11%]); 74 (56%) patients had serious treatment-emergent adverse events, most commonly pyrexia (16 [12%]). One (1%) fatal treatment-emergent adverse event and two (2%) deaths outside the reporting period were considered at least possibly study-drug related. Antitumoural activity was seen in classical Hodgkin and non-Hodgkin lymphomas; notably in all patients with classical Hodgkin lymphoma, the overall response was 71% (95% CI 60-81). INTERPRETATION These results warrant evaluation of camidanlumab tesirine as a potential treatment option for relapsed or refractory lymphoma, particularly in patients with classical Hodgkin lymphoma.

Abstract
PURPOSE OF REVIEW There are limited treatment options for relapsed/refractory classical Hodgkin lymphoma (cHL) patients who progress on brentuximab vedotin and programmed death-1 inhibitors. Camidanlumab Tesirine (Cami) is a new agent that has shown activity in multiply relapsed/refractory cHL patients. In this review, we provide a comprehensive overview of Cami. RECENT FINDINGS In phase 1 study of Cami in relapsed/refractory cHL and non-Hodgkin lymphomas (NHL), Cami was noted to be safe with encouraging clinic activity in multiply relapsed/refractory cHL. Treatment-emergent adverse events (TEAEs) were reported in 95% (n = 73 of 77) of patients, while grade 3 TEAEs were reported in 66% (n = 51) of cHL patients. Cami was associated with immune-related adverse events (irAEs) including peripheral sensory neuropathy, Guillain-Barré syndrome (GBS)/radiculopathy, colitis, hypothyroidism, hyperthyroidism, thyroiditis, and pneumonitis. The overall response rate (ORR) and complete (CR) rate were 71%/40% in the cHL cohort (n = 75). In the interim analysis of an ongoing phase 2 study in 2020, Cami demonstrated good clinical efficacy with an ORR/CR rate of 83%/38% among the 47 evaluable cHL patients. The toxicity profile was similar to that seen in the phase 1 study, with no new safety signals.. As the phase 2 study with Cami is continuing to accrue patients and we await the final results, the preliminary results with Cami are encouraging and provide an additional therapeutic option especially for patients with multiply relapsed/refractory cHL and perhaps other hematological malignancies expression CD25.

Abstract
Interleukin-2 (IL-2) is integral to immune system regulation. Its opposing immunostimulatory and immunosuppressive actions make it an attractive therapeutic target for cancer and autoimmune diseases. A challenge in developing IL-2-directed anticancer therapies has been how to stimulate effector T cells (Teffs) without inducing regulatory T cells (Tregs) in the tumor microenvironment; conversely, IL-2 therapy for autoimmune diseases requires Treg induction without further stimulation of Teffs. High-dose IL-2 is approved for melanoma and renal cell carcinoma, but its therapeutic value is limited by a need for frequent dosing at specialist centers, its short half-life, severe toxicity, and a lack of efficacy in most patients. Re-engineered IL-2 therapeutics are designed to have longer in vivo half-lives, target specific IL-2 receptor conformations to stimulate specific T cell subsets, or localize to target tissues to optimize efficacy and reduce toxicity. We discuss recent studies that elucidate the potential of newly engineered IL-2-based therapeutics for cancer and autoimmune diseases.

CD25-targeted antibody-drug conjugate depletes regulatory T cells and eliminates established syngeneic tumors via antitumor immunity. J Immunother Cancer 2020; 8:jitc-2020-000860.

Abstract
Background Regulatory T cells (Tregs) contribute to an immunosuppressive tumor microenvironment. They play an important role in the establishment and progression of tumors with high Tregs infiltration and present a major obstacle to tumor eradication by immunotherapies. Numerous strategies have been attempted to deplete or block Tregs, although their success has been limited. Methods A CD25-targeted, pyrrolobenzodiazepine (PBD) dimer-based antibody–drug conjugate (ADC) was investigated for its ability to deplete Tregs and induce antitumor immunity. Antitumor activity of CD25-ADC either alone or in combination with an anti-programmed cell death protein 1 (PD-1) antibody was evaluated in CD25-negative syngeneic models that exhibit tumor infiltration of CD25-expressing Tregs, and its pharmacodynamics and pharmacokinetics were assessed. Results Single low doses of CD25-ADC resulted in potent and durable antitumor activity in established syngeneic solid tumor models and the combination of a suboptimal dose was synergistic with PD-1 blockade. Tumor eradication by the CD25-targeted ADC was CD8+ T cell-dependent and CD25-ADC induced protective immunity. Importantly, while CD25-ADC mediated a significant and sustained intratumoral Tregs depletion, accompanied by a concomitant increase in the number of activated and proliferating tumor-infiltrating CD8+ T effector cells, systemic Tregs depletion was transient, alleviating concerns of potential autoimmune side effects. Conclusions This study shows that a PBD dimer-based, CD25-targeted ADC is able to deplete Tregs and eradicate established tumors via antitumor immunity. This represents a novel approach to efficiently deplete Tregs via a very potent DNA damaging toxin known to induce immunogenic cell death. Moreover, this study provides proof of concept for a completely new application of ADCs as immunotherapeutic agents, as the main mode of action relies on the ADC directly targeting immune cells, rather than tumor cells. These strong preclinical data warrant the clinical evaluation of camidanlumab tesirine (ADCT-301), a PBD-based ADC targeting human CD25, either alone or in combination with checkpoint inhibitors in solid tumors with known Tregs infiltration. A phase I trial (NCT03621982) of camidanlumab tesirine in patients with selected advanced solid tumors is ongoing.

Abstract
INTRODUCTION The rationally designed pyrrolobenzodiazepine (PBD) dimers emerged around ten years ago as a new class of drug component for antibody-drug conjugates (ADC). They produce highly cytotoxic DNA cross-links, exploiting a completely different cellular target to the auristatin and maytansinoid tubulin inhibitor classes and a different mode of DNA damage to other DNA interacting warheads such as calicheamicin. AREAS COVERED The properties which make the PBD dimers suitable warheads for ADCs, and the development of the two main payload structures talirine and tesirine, are discussed. The clinical experience with the twenty PBD dimer-containing ADCs to enter the clinic is reviewed, with a focus on vadastuximab talirine and rovalpituzumab tesirine, both of which were discontinued following pivotal studies, and loncastuximab tesirine and camidanlumab tesirine which are progressing towards approval. EXPERT OPINION Reviewing the clinical efficacy and safety data from almost forty clinical trials of PBD dimer-containing ADCs highlights the complexities and challenges of ADC early clinical development. It enables some conclusions to be made about reasons for failure and suggests strategies to optimise the future clinical development of this promising class of ADCs in a rapidly expanding field.
