Project description:BackgroundPatients with relapsed or refractory chronic lymphocytic leukaemia or small lymphocytic lymphoma for whom treatment has failed with both Bruton tyrosine kinase (BTK) inhibitor and venetoclax have few treatment options and poor outcomes. We aimed to evaluate the efficacy and safety of lisocabtagene maraleucel (liso-cel) at the recommended phase 2 dose in patients with relapsed or refractory chronic lymphocytic leukaemia or small lymphocytic lymphoma.MethodsWe report the primary analysis of TRANSCEND CLL 004, an open-label, single-arm, phase 1-2 study conducted in the USA. Patients aged 18 years or older with relapsed or refractory chronic lymphocytic leukaemia or small lymphocytic lymphoma and at least two previous lines of therapy, including a BTK inhibitor, received an intravenous infusion of liso-cel at one of two target dose levels: 50 × 106 (dose level 1) or 100 × 106 (dose level 2, DL2) chimeric antigen receptor-positive T cells. The primary endpoint was complete response or remission (including with incomplete marrow recovery), assessed by independent review according to the 2018 International Workshop on Chronic Lymphocytic Leukemia criteria, in efficacy-evaluable patients with previous BTK inhibitor progression and venetoclax failure (the primary efficacy analysis set) at DL2 (null hypothesis of ≤5%). This trial is registered with ClinicalTrials.gov, NCT03331198.FindingsBetween Jan 2, 2018, and June 16, 2022, 137 enrolled patients underwent leukapheresis at 27 sites in the USA. 117 patients received liso-cel (median age 65 years [IQR 59-70]; 37 [32%] female and 80 [68%] male; 99 [85%] White, five [4%] Black or African American, two [2%] other races, and 11 [9%] unknown race; median of five previous lines of therapy [IQR 3-7]); all 117 participants had received and had treatment failure on a previous BTK inhibitor. A subset of patients had also experienced venetoclax failure (n=70). In the primary efficacy analysis set at DL2 (n=49), the rate of complete response or remission (including with incomplete marrow recovery) was statistically significant at 18% (n=9; 95% CI 9-32; p=0·0006). In patients treated with liso-cel, grade 3 cytokine release syndrome was reported in ten (9%) of 117 (with no grade 4 or 5 events) and grade 3 neurological events were reported in 21 (18%; one [1%] grade 4, no grade 5 events). Among 51 deaths on the study, 43 occurred after liso-cel infusion, of which five were due to treatment-emergent adverse events (within 90 days of liso-cel infusion). One death was related to liso-cel (macrophage activation syndrome-haemophagocytic lymphohistiocytosis).InterpretationA single infusion of liso-cel was shown to induce complete response or remission (including with incomplete marrow recovery) in patients with relapsed or refractory chronic lymphocytic leukaemia or small lymphocytic lymphoma, including patients who had experienced disease progression on a previous BTK inhibitor and venetoclax failure. The safety profile was manageable.FundingJuno Therapeutics, a Bristol-Myers Squibb Company.

Project description:An unmet need exists for patients with relapsed/refractory (R/R) follicular lymphoma (FL) and high-risk disease features, such as progression of disease within 24 months (POD24) from first-line immunochemotherapy or disease refractory to both CD20-targeting agent and alkylator (double refractory), due to no established standard of care and poor outcomes. Chimeric antigen receptor (CAR) T cell therapy is an option in R/R FL after two or more lines of prior systemic therapy, but there is no consensus on its optimal timing in the disease course of FL, and there are no data in second-line (2L) treatment of patients with high-risk features. Lisocabtagene maraleucel (liso-cel) is an autologous, CD19-directed, 4-1BB CAR T cell product. The phase 2 TRANSCEND FL study evaluated liso-cel in patients with R/R FL, including 2L patients who all had POD24 from diagnosis after treatment with anti-CD20 antibody and alkylator ≤6 months of FL diagnosis and/or met modified Groupe d'Etude des Lymphomes Folliculaires criteria. Primary/key secondary endpoints were independent review committee-assessed overall response rate (ORR)/complete response (CR) rate. At data cutoff, 130 patients had received liso-cel (median follow-up, 18.9 months). Primary/key secondary endpoints were met. In third-line or later FL (n = 101), ORR was 97% (95% confidence interval (CI): 91.6‒99.4), and CR rate was 94% (95% CI: 87.5‒97.8). In 2L FL (n = 23), ORR was 96% (95% CI: 78.1‒99.9); all responders achieved CR. Cytokine release syndrome occurred in 58% of patients (grade ≥3, 1%); neurological events occurred in 15% of patients (grade ≥3, 2%). Liso-cel demonstrated efficacy and safety in patients with R/R FL, including high-risk 2L FL. ClinicalTrials.gov identifier: NCT04245839 .

Project description:The autologous anti-CD19 chimeric antigen receptor (CAR) T-cell product, lisocabtagene maraleucel (liso-cel), is administered at equal target doses of CD8+ and CD4+ CAR+ T cells. This analysis assessed safety and efficacy of liso-cel in Japanese patients with relapsed or refractory (R/R) aggressive large B-cell lymphoma (LBCL) in Cohort 3 of TRANSCEND WORLD (NCT03484702). Liso-cel (100 × 106 total CAR+ T cells) was administered 2-7 days after lymphodepletion. The primary efficacy endpoint was objective response rate (ORR; Lugano 2014 criteria) assessed by an independent review committee. Fourteen patients were enrolled; 10 received liso-cel infusion (median time to liso-cel availability, 23 days) and were evaluable at data cutoff (median follow-up, 12.5 months). Grade ≥ 3 treatment-emergent adverse events were neutropenia (90%), leukopenia (80%), anemia (70%), and thrombocytopenia (70%). All-grade cytokine release syndrome (CRS) was observed in 50% of patients, though no grade ≥3 CRS events were reported. Grade 1 neurological events occurred in 1 patient but were resolved without any intervention. Prolonged cytopenia (grade ≥ 3 at day 29) was reported for 60% of patients. The ORR was 70%, and complete response rate was 50%. The median duration of response was 9.1 months (95% confidence interval [CI], 2.1-not reached), and overall survival was 14.7 months (95% CI, 1.7-not reached). One patient diagnosed with central nervous system involvement after screening but before liso-cel infusion, responded to liso-cel. Liso-cel demonstrated meaningful efficacy and a manageable safety profile in Japanese patients with R/R LBCL.

Project description:PurposeTo report the primary analysis results from the mantle cell lymphoma (MCL) cohort of the phase I seamless design TRANSCEND NHL 001 (ClinicalTrials.gov identifier: NCT02631044) study.MethodsPatients with relapsed/refractory (R/R) MCL after ≥two lines of previous therapy, including a Bruton tyrosine kinase inhibitor (BTKi), an alkylating agent, and a CD20-targeted agent, received lisocabtagene maraleucel (liso-cel) at a target dose level (DL) of 50 × 106 (DL1) or 100 × 106 (DL2) chimeric antigen receptor-positive T cells. Primary end points were adverse events (AEs), dose-limiting toxicities, and objective response rate (ORR) by independent review committee per Lugano criteria.ResultsOf 104 leukapheresed patients, liso-cel was infused into 88. Median (range) number of previous lines of therapy was three (1-11) with 30% receiving ≥five previous lines of therapy, 73% of patients were age 65 years and older, 69% had refractory disease, 53% had BTKi refractory disease, 23% had TP53 mutation, and 8% had secondary CNS lymphoma. Median (range) on-study follow-up was 16.1 months (0.4-60.5). In the efficacy set (n = 83; DL1 + DL2), ORR was 83.1% (95% CI, 73.3 to 90.5) and complete response (CR) rate was 72.3% (95% CI, 61.4 to 81.6). Median duration of response was 15.7 months (95% CI, 6.2 to 24.0) and progression-free survival was 15.3 months (95% CI, 6.6 to 24.9). Most common grade ≥3 treatment-emergent AEs were neutropenia (56%), anemia (37.5%), and thrombocytopenia (25%). Cytokine release syndrome (CRS) was reported in 61% of patients (grade 3/4, 1%; grade 5, 0), neurologic events (NEs) in 31% (grade 3/4, 9%; grade 5, 0), grade ≥3 infections in 15%, and prolonged cytopenia in 40%.ConclusionLiso-cel demonstrated high CR rate and deep, durable responses with low incidence of grade ≥3 CRS, NE, and infections in patients with heavily pretreated R/R MCL, including those with high-risk, aggressive disease.

Project description:Duvelisib (also known as IPI-145) is an oral, dual inhibitor of phosphatidylinositol 3-kinase δ and γ (PI3K-δ,γ) being developed for treatment of hematologic malignancies. PI3K-δ,γ signaling can promote B-cell proliferation and survival in clonal B-cell malignancies, such as chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). In a phase 1 study, duvelisib showed clinically meaningful activity and acceptable safety in CLL/SLL patients. We report here the results of DUO, a global phase 3 randomized study of duvelisib vs ofatumumab monotherapy for patients with relapsed or refractory (RR) CLL/SLL. Patients were randomized 1:1 to oral duvelisib 25 mg twice daily (n = 160) or ofatumumab IV (n = 159). The study met the primary study end point by significantly improving progression-free survival per independent review committee assessment compared with ofatumumab for all patients (median, 13.3 months vs 9.9 months; hazard ratio [HR] = 0.52; P < .0001), including those with high-risk chromosome 17p13.1 deletions [del(17p)] and/or TP53 mutations (HR = 0.40; P = .0002). The overall response rate was significantly higher with duvelisib (74% vs 45%; P < .0001) regardless of del(17p) status. The most common adverse events were diarrhea, neutropenia, pyrexia, nausea, anemia, and cough on the duvelisib arm, and neutropenia and infusion reactions on the ofatumumab arm. The DUO trial data support duvelisib as a potentially effective treatment option for patients with RR CLL/SLL. This trial was registered at www.clinicaltrials.gov as #NCT02004522.

Project description:Zanubrutinib is a selective second-generation Bruton tyrosine kinase inhibitor approved in various B-cell malignancies globally. The phase 1/2 BGB-3111-111 study evaluated the efficacy and safety of zanubrutinib 160 mg twice daily orally in Japanese patients with treatment-naive or relapsed/refractory mature B-cell malignancies. Here, efficacy results from Part 2 in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL; n = 19) and Waldenström macroglobulinemia (WM; n = 19), and safety results from Parts 1 (N = 6) and 2 (N = 49) are presented, with the first dose between 30 January, 2020, and 31 October, 2022. As of 10 May, 2023, investigator-assessed overall response rates were 100% (19/19) and 94.7% (18/19) in CLL/SLL and WM, respectively, with median follow-up of 27.9 and 26.8 months; 24-month progression-free survival rates were 71.4% and 100% in treatment-naive and relapsed/refractory CLL/SLL and 83.9% and 100% in treatment-naive and relapsed/refractory WM, respectively. In patients with B-cell malignancies, any-grade treatment-emergent adverse events (TEAEs) occurred in 53 (96.4%) and serious TEAEs in 18 (32.7%). Common TEAEs were platelet count decreased (18.2%), pyrexia (18.2%), COVID-19 (14.5%), and neutrophil count decreased (12.7%). With median follow-up > 2 years, zanubrutinib demonstrated durable efficacy in Japanese patients with CLL/SLL or WM and a favorable safety profile consistent with global phase 3 studies.

Project description:AbstractLisocabtagene maraleucel (liso-cel), a chimeric antigen receptor (CAR) T-cell therapy, received the US Food and Drug Administration approval in 2022 for second-line treatment of diffuse large B-cell lymphoma (DLBCL) for patients with refractory disease or early relapse after first-line chemoimmunotherapy. This decision was based on the TRANSFORM study demonstrating improvements in event-free survival with liso-cel compared with standard care. Given the high costs of CAR T-cell therapies, particularly as they transition to second-line treatment, a cost-effectiveness analysis is essential to determine their economic viability. The study used a partitioned survival model with standard parametric functions to evaluate the cost-effectiveness of liso-cel aganist platinum-based chemotherapy followed by high-dose chemotherapy and autologous hematopoietic stem cell transplantation over a lifetime horizon The analysis relied on data from the TRANSFORM and TRANSCEND trials, established literature, and public data sets to calculate the incremental cost-effectiveness ratio (ICER). For a representative cohort of US adults aged 60 years, ICER of liso-cel was $99 669 per quality-adjusted life-year (QALY) from a health care sector perspective and $68 212 per QALY from a societal perspective, confirming its cost-effectiveness at the $100 000 per QALY threshold. Nonetheless, under certain scenarios, liso-cel surpasses this benchmark but remains within the US acceptable range of $150 000 per QALY. A key finding underlines the importance of incorporating productivity losses into such analyses to capture the broader societal values of novel therapies. Although these therapies offer substantial clinical benefits, their high acquisition costs and limited long-term data critically challenge their economic sustainability.

Project description:CD19-directed chimeric antigen receptor (CAR) T-cell therapy has shown efficacy as a third-line or later treatment in patients with relapsed/refractory large B-cell lymphoma (LBCL). Using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire, we evaluated the impact of CAR T-cell treatment with lisocabtagene maraleucel (liso-cel) on health-related quality of life (HRQoL) and symptoms in patients with relapsed/refractory LBCL in the ongoing, open-label, nonrandomized TRANSCEND NHL 001 trial. Clinically meaningful improvement was observed in EORTC QLQ-C30 scores for global health status/QoL, based on a minimally important difference of 10 points at 2 to 18 months after liso-cel infusion. There were no clinically meaningful changes in physical functioning and pain, whereas clinically meaningful improvements were observed in fatigue at 2, 12, and 18 months. The proportion of patients with clinically meaningful improvement in global health status/QoL was generally higher for treatment responders than for nonresponders. A trend toward decreased mean EQ-5D-5L index scores was observed at 1 month after liso-cel infusion, followed by subsequent increases through 18 months. Mean EQ-5D-5L visual analog scale scores increased from 2 through 18 months. In summary, patients with relapsed/refractory LBCL treated with liso-cel had early, sustained, and clinically meaningful improvements in HRQoL and symptoms that correlated with antitumor activity. This study was registered at www.clinicaltrials.gov as #NCT02631044.

Project description:Chimeric antigen receptor (CAR) T-cell therapies have demonstrated high response rates in patients with relapsed/refractory large B-cell lymphoma (LBCL); however, these therapies are associated with 2 CAR T cell-specific potentially severe adverse events (AEs): cytokine release syndrome (CRS) and neurological events (NEs). This study estimated the management costs associated with CRS/NEs among patients with relapsed/refractory LBCL using data from the pivotal TRANSCEND NHL 001 trial of lisocabtagene maraleucel, an investigational CD19-directed defined composition CAR T-cell product with a 4-1BB costimulation domain administered at equal target doses of CD8+ and CD4+ CAR+ T cells. This retrospective analysis of patients from TRANSCEND with prospectively identified CRS and/or NE episodes examined relevant trial-observed health care resource utilization (HCRU) associated with toxicity management based on the severity of the event from the health care system perspective. Cost estimates for this analysis were taken from publicly available databases and published literature. Of 268 treated patients as of April 2019, 127 (47.4%) experienced all-grade CRS and/or NEs, which were predominantly grade ≤2 (77.2%). Median total AE management costs ranged from $1930 (grade 1 NE) to $177 343 (concurrent grade ≥3 CRS and NE). Key drivers of cost were facility expenses, including intensive care unit and other inpatient hospitalization lengths of stay. HCRU and costs were significantly greater among patients with grade ≥3 AEs (22.8%). Therefore, CAR T-cell therapies with a low incidence of severe CRS/NEs will likely reduce HCRU and costs associated with managing patients receiving CAR T-cell therapy. This clinical trial was registered at www.clinicaltrials.gov as #NCT02631044.

Project description:Lisocabtagene maraleucel (liso-cel) has shown promising efficacy in clinical trials for patients with relapsed/refractory large B-cell lymphoma (LBCL). We present health-related quality of life (HRQOL) results from the TRANSFORM study, the first comparative analysis of liso-cel vs standard of care (SOC) as second-line therapy in this population. Adults with LBCL refractory or relapsed ≤12 months after first-line therapy and eligible for autologous stem cell transplantation were randomized 1:1 to the liso-cel or SOC arms (3 cycles of immunochemotherapy in which responders proceeded to high-dose chemotherapy and autologous stem cell transplantation). HRQOL was assessed by European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - 30 items and the Functional Assessment of Cancer Therapy-Lymphoma subscale. Patients with baseline and ≥1 postbaseline assessment were analyzed (liso-cel, n = 47; SOC, n = 43). The proportion of patients with meaningful improvement in global health status/quality of life (QOL) was higher, whereas deterioration was lower in the liso-cel arm vs SOC arm from day 126 to month 6. Mean change scores showed meaningful worsening in global health status/QOL at month 6, fatigue at day 29 and month 6, and pain at month 6 with SOC; mean scores for other domains were maintained or improved in both arms. Time to confirmed deterioration favored the liso-cel arm vs SOC arm in global health status/QOL (median: not reached vs 19.0 weeks, respectively; hazard ratio, 0.47; 95% confidence interval, 0.24-0.94). HRQOL was either improved or maintained from baseline in patients with relapsed/refractory LBCL in the liso-cel arm vs SOC arm as second-line treatment. This study is registered at clinicaltrials.gov as #NCT0357531.
