Project description:The efficacy of loncastuximab tesirine (lonca) following chimeric antigen receptor T-cell therapy (CAR-T) progression/failure is unknown. Hence, we sought to examine real-world use and outcomes of lonca following CAR-T in patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) in the USA. In this retrospective study, we included adults (age ≥ 18 years) with R/R DLBCL who received lonca monotherapy as third- (3 L) or fourth line (4 L) treatment after progressing on second line (2 L) or 3 L CAR-T, respectively. Post-CAR-T lonca outcomes included response rates (overall response rate [ORR] and complete response [CR] rate), duration of response (DOR), progression-free survival (PFS), and overall survival (OS). A total of 118 patients were included in the analysis with 95 receiving lonca following 2 L CAR-T (median age:66 years; 61% male) and 23 following 3 L CAR-T (median age:57 years; 43% male). Patients with 2 L CAR-T/3 L lonca had an ORR of 73% (CR rate of 34%). With a median follow-up of 8.5 months following lonca initiation, median DOR, PFS, and OS were not reached. The DOR, PFS, and OS at 12 months were 68%, 77%, and 84%, respectively. Patients with 3 L CAR-T/4 L lonca had an ORR of 78% (CR rate of 17%). With a median follow-up of 13 months following lonca initiation, the median DOR and PFS were 7.6 and 12.0 months, while median OS was not reached. OS at 12 months was 95%. In this study, we found that lonca monotherapy was an effective treatment option in R/R DLBCL in 3 L and 4 L settings including those who were resistant to or progressed after CAR-T.

Project description:Loncastuximab tesirine-lpyl (ADC Therapeutics) is an anti-CD19 antibody-drug conjugate which consists of anti-CD19 antibody and cytotoxic alkylating agent, SG3199. Data from preclinical in vitro and animal studies demonstrated its selectivity and efficacy. The phase I LOTIS-1 study for relapsed, refractory B-cell non-Hodgkin lymphoma (NHL) demonstrated efficacy and a tolerable safety profile, with major adverse effects being neutropenia, thrombocytopenia, elevated liver enzymes, and fluid accumulation. Based on pharmacokinetics analysis in this study, a dose of 150 μg/kg every 3 weeks for cycles 1 and 2 followed by 75 μg/kg every 3 weeks until disease progression or intolerability was chosen for the phase II LOTIS-2 study. This study recruited relapsed, refractory diffuse large B-cell lymphoma and confirmed similar safety profile. Overall response rate was 48.6% (24.1% complete response), and overall survival was 9.9 months. Due to its safety and efficacy reported in the above trials, loncastuximab tesirine was recently approved by the US Food and Drug Administration for the treatment of relapsed, refractory diffuse large B-cell lymphoma. Several clinical trials are ongoing to assess its safety and efficacy in NHL in various clinical settings.

Project description:Diffuse large B-cell lymphoma (DLBCL) is a heterogenous subtype of non-Hodgkin lymphoma. Relapsed/refractory disease represents remains an unmet medical need, despite the introduction of novel cellular and targeted therapies. Loncastuximab tesirine is a cluster of differentiation19-targeting antibody-drug conjugate approved by the US Food and Drug Administration for relapsed DLBCL after 2 lines of systemic therapy based on a trial showing a 48.3% overall response rate. The spectrum of its clinical applications is expanding and is now being tested in other B-cell malignancies.

Project description:BackgroundNeoadjuvant chemoradiation (nCRT) followed by esophagectomy is the standard treatment for locally advanced esophageal cancer. Older patients are often felt to be poor candidates for nCRT. Limited data is available to guide the use of nCRT in this population.MethodsA retrospective review of patients treated at a tertiary cancer center between 2002 and 2014 was conducted grouping patients by age (≥ 65 or < 65) for evaluation of differences in toxicity and outcomes. Evaluation of pre-treatment platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) was also performed. Univariate (UVA) and multivariate analyses (MVA) determined associations between age, toxicities and outcomes. The Kaplan-Meier method (KM) assessed overall survival (OS) and relapse free survival (RFS).Results125 patients were identified for this study (67 aging <65, and 58 ≥ 65). In the UVA, advanced age was only associated with increased hematologic toxicity (p = .04). After adjusting for covariates in the MVA, there were no significant differences in toxicity between older and younger patients. There were also no differences between overall survival and relapse free survival between age groups. Increased pre-treatment NLR was strongly correlated with advanced age (p = .01), increased hospitalizations (p = .04), and decreased RFS (p = .002).ConclusionsOlder patients who underwent nCRT followed by esophagectomy had similar toxicities and outcomes as younger patients suggesting that nCRT before esophagectomy is safe in select older adults with esophageal cancer. PLR and NLR may serve as prognostic markers of aging, toxicity, and outcomes. Further research is warranted to optimize the therapy of older patients with this disease.

Project description:Relapsed or refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL) remains a therapeutic challenge. Loncastuximab tesirine is an antibody-drug conjugate against CD19, an antigen expressed in many B-cell malignancies. This open-label, single-arm, dose-escalation, dose-expansion study assessed the safety, tolerability, pharmacokinetics (PKs), immunogenicity, and preliminary clinical activity of loncastuximab tesirine in adults with R/R B-ALL. A total of 35 patients were enrolled, with a median age of 55 years (range, 20-80) and a median of 3 prior therapies (range, 1-15). All patients received at least 1 IV infusion of loncastuximab tesirine at 15 to 150 μg/kg once every 3 weeks (Q3W; n = 30) or 50 μg/kg IV weekly (n = 5). Common treatment-emergent adverse events (TEAEs) were nausea (42.9%), febrile neutropenia (37.1%), and reversible liver test abnormalities. Grade ≥3 TEAEs were reported in 85.7% patients, most commonly febrile neutropenia and other hematologic abnormalities and reversible liver test abnormalities. There were no treatment-related deaths. Four patients (11.4%) had grade 2 infusion-related reactions, and 1 patient (150 μg/kg Q3W) had a dose-limiting toxicity of hyperbilirubinemia that resolved within 6 days without further action. The maximum tolerated dose was not reached. Three patients achieved complete responses, 1 each at 30, 120, and 150 μg/kg Q3W. PK studies showed marked interpatient variability, with target-mediated drug disposition seeming to contribute to time- and dose-dependent disposition. No clinically relevant anti-drug-antibody formation occurred. The trial was terminated in the dose-escalation phase because of slow accrual. This trial was registered at www.clinicaltrials.gov as NCT02669264.

Project description:The prognosis for patients with relapsed or refractory (R/R) B-cell non-Hodgkin lymphoma (B-NHL) remains poor, with a need for alternatives to current salvage therapies. Loncastuximab tesirine (ADCT-402) is an antibody-drug conjugate comprising a humanized anti-CD19 monoclonal antibody conjugated to a pyrrolobenzodiazepine dimer toxin. Presented here are final results of a phase 1 dose-escalation and dose-expansion study in patients with R/R B-NHL. Objectives were to determine the maximum tolerated dose (MTD) and recommended dose(s) for expansion and evaluate safety, clinical activity, pharmacokinetics, and immunogenicity of loncastuximab tesirine. Overall, 183 patients received loncastuximab tesirine, with 3 + 3 dose escalation at 15 to 200 µg/kg and dose expansion at 120 and 150 µg/kg. Dose-limiting toxicities (all hematologic) were reported in 4 patients. The MTD was not reached, although cumulative toxicity was higher at 200 µg/kg. Hematologic treatment-emergent adverse events were most common, followed by fatigue, nausea, edema, and liver enzyme abnormalities. Overall response rate (ORR) in evaluable patients was 45.6%, including 26.7% complete responses (CRs). ORRs in patients with diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma, and follicular lymphoma were 42.3%, 46.7%, and 78.6%, respectively. Median duration of response in all patients was 5.4 months and not reached in patients with DLBCL (doses ≥120 µg/kg) who achieved a CR. Loncastuximab tesirine had good stability in serum, notable antitumor activity, and an acceptable safety profile, warranting continued study in B-NHL. The recommended dose for phase 2 was determined as 150 µg/kg every 3 weeks for 2 doses followed by 75 µg/kg every 3 weeks. This trial was registered at www.clinicaltrials.gov as #NCT02669017.

Project description:BackgroundGenerally, little is known about prognostic factors in bladder cancer patients under 40 years of age. We therefore performed a retrospective study to identify prognostic factors in these younger bladder cancer patients.MethodsWe collected clinicopathological data on bladder cancer patients ≤40 years old diagnosed between 1975 and 2018 from the Surveillance, Epidemiology, and End Results (SEER) database. Survival curves were generated using the Kaplan-Meier method, and the differences between groups were analyzed using the log-rank test. Univariate and multivariate Cox hazards regression analyses were performed to define hazard ratios (HRs) for cancer-specific survival (CSS).ResultsThere were statistical differences in race, histological type, cancer stage, tumor size, and surgery treatment groups between overall survival and CSS. Only tumor size and cancer stage were significant independent prognostic risk factors in younger bladder cancer patients for the prediction of CSS.ConclusionTumors greater than 30 mm in size and a more advanced stage of bladder cancer were indicative of a poor prognosis in bladder cancer patients ≤40 years old, and long-term follow-up is suggested.

Project description:Although younger patients with allergic rhinitis (AR) have been successfully treated with pharmacotherapy, there are no definitive data on treatment outcomes in older patients with AR. We performed a prospective study of 51 older adults with AR (aged over 65 years) and 101 younger AR patients (aged from 19 to 40 years) to compare clinical outcomes between the 2 groups and to evaluate the impact of depressed mood on treatment outcomes in older AR patients. Changes in total symptom scores (TSS), rhinitis-specific quality of life questionnaire (RQLQ) results, rhinitis control assessment test (RCAT) results and visual analog scale (VAS) scores were evaluated after 4-week treatment according to the Allergic Rhinitis and its Impact on Asthma (ARIA) guideline, and the severity of depressed mood was assessed by using the geriatric depression scale. After 4-week treatment, younger AR patients had greater improvements in clinical scores compared with older adults; differences in least squares mean changes from baseline in older patients vs. younger patients were 1.71 (P = 0.004) for TSS, 10.84 (P < 0.001) for RQLQ, 0.80 (P = 0.275) for RCAT, and 8.60 for VAS score (P = 0.061). Multiple logistic regression analysis showed that the severity of depressed mood was independently associated with severe chronic upper airway disease (adjusted odds ratio, 1.385; P = 0.004). Our results suggest that older AR patients are less responsive to standard treatment compared with younger AR patients and that depressed mood is strongly associated with the increased risk of uncontrolled AR in older AR patients.
