ZANDELISIB, A PI3Kδ INHIBITOR ON INTERMITTENT SCHEDULE (IS) IN FOLLICULAR LYMPHOMA PATIENTS WHO PROGRESSED WITHIN 24 MONTHS OF FIRST‐LINE CHEMOIMUNOTHERAPY (POD24)

Purpose Twenty percent of patients with follicular lymphoma (FL) experience progression of disease (POD) within 2 years of initial chemoimmunotherapy. We analyzed data from the National LymphoCare Study to identify whether prognostic FL factors are associated with early POD and whether patients with early POD are at high risk for death. Patients and Methods In total, 588 patients with stage 2 to 4 FL received first-line rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Two groups were defined: patients with early POD 2 years or less after diagnosis and those without POD within 2 years, the reference group. An independent validation set, 147 patients with FL who received first-line R-CHOP, was analyzed for reproducibility. Results Of 588 patients, 19% (n = 110) had early POD, 71% (n = 420) were in the reference group, 8% (n = 46) were lost to follow-up, and 2% (n = 12) died without POD less than 2 years after diagnosis. Five-year overall survival was lower in the early-POD group than in the reference group (50% v 90%). This trend was maintained after we adjusted for FL International Prognostic Index (hazard ratio, 6.44; 95% CI, 4.33 to 9.58). Results were similar for the validation set (FL International Prognostic Index–adjusted hazard ratio, 19.8). Conclusion In patients with FL who received first-line R-CHOP, POD within 2 years after diagnosis was associated with poor outcomes and should be further validated as a standard end point of chemoimmunotherapy trials of untreated FL. This high-risk FL population warrants further study in directed prospective clinical trials.

First Line Treatment

The natural history of follicular lymphoma is usually characterized by an indolent course with a high response rate to the first line therapy followed by recurrent relapses, with a time to next treatment becoming shorter after each subsequent treatment line. More than 80% of patients have advanced stage disease at diagnosis. The time of initiation and the nature of the treatment is mainly conditioned by symptoms, tumor burden, lymphoma grading, co-morbidities and patients preference. A number of clinical and biological factors have been determined to be prognostic in this disease, but the majority of them could not show to be predictive of response to treatment, and therefore can’t be used to guide the treatment choice. CD20 expression is the only predictive factor recognized in the treatment of FL and justifies the use of “naked” or “conjugated” anti-CD20 monoclonal antibodies as single agent or in combination with chemo- or targeted therapy. Nevertheless, as this marker is almost universally found in FL, it has little role for the choice of treatment. The outcome of patients with FL improved significantly in the last years, mainly due to the widespread use of rituximab, autologous and allogeneic transplantation in young and fit relapsed patients, the introduction of new drugs and the improvement in diagnostic accuracy and management of side effects. Agents as new monoclonal antibodies, immuno-modulating drugs and target therapy have recently been developed and approved for the relapsed setting, while studies to evaluate their role in first line treatment are still ongoing. Here we report our considerations on first line treatment approach and on the potential factors which could help in the choice of therapy.

Budget Impact Model

Introduction: The choice of initial therapy in follicular lymphoma can be a key determinant in future therapy, as irreversible toxicities with first line regimens can impact the patient's ability to tolerate future treatment. Minimizing drug exposure will result in less frequent occurrence of significant adverse events and associated treatment costs. In the era of COVID-19 pandemic, there is additional benefit to minimizing the number of patient visits and hospital admissions. Limited information exists related to the outcomes and associated costs of existing treatment sequences. Additionally, treatment administration at different types of clinical sites results in varied reimbursement models, making informed evaluation of clinical and financial evidence challenging. Methods: The current study applies a budget impact model methodology in order to describe the associated impact of treatment selection and sequencing on outcomes and costs in the treatment of relapsed or refractory low-grade follicular lymphoma in first line therapy followed by Consolidation and also in first line therapy to second line therapy. Key model inputs included: Number of treatment cycles, number of days a treatment was received, duration of response (DOR), rate of side effects and associated costs, and total treatment costs, including drugs, medical treatment, laboratory testing and adverse event costs. Treatment outcomes were based on the published literature that summarized the overall response rate, median DOR, and toxicity. Treatment regimen costs were evaluated based on payer pricing, Wholesale Acquisition Cost (WAC), Average Selling Price (ASP) and Average Wholesale Price (AWP) and modified to adjust for weight-based dosing and negotiate payer reimbursement rates. Associated medical costs for medical treatment and supportive care were estimated using current Medicare fee schedule rates. Included were seven options for first line therapy of follicular lymphoma from 2020 NCCN Guidelines - (Bendamustine + rituximab (BR); Bendamustine + Obinutuzumab (OB); CHOP rituximab (RCHOP); CHOP + Obinutuzumab (OCHOP); CVP+ rituximab (RCVP); CVP + Obinutuzumab (OCVP); Lenalidomide + rituximab (R2)), followed by three for Consolidation (Rituximab maintenance (RM); Obinutuzumab maintenance (O); Radioimmunotherapy (RIT with 90 Y-ibritumomab tiuxetan (Y90-IT, Zevalin)) and three Second Line therapy options (RIT; Lenalidomide only; Lenalidomide + Obinutuzumab (LO)). Results: The treatment sequence of first line BR followed by Consolidation with RIT Y90 (Zevalin) had the longest predicted DOR (2586 days). The associated treatment sequence costs were $212,485 for BR followed by Y90-IT, compared with $233, 388 for BR followed by rituximab maintenance, which had a predicted DOR of 2478 days. The predicted DOR for treatment sequences starting with OCHOP, OCVP and RCHOP and followed by RIT with Y90-IT was approximately 1000 days less than BR followed by Y90-IT for a cost difference of $4,421, $12,914 and $25,826, respectively. The treatment sequence of first line BR followed by Second Line RIT Y90-IT had the second longest predicted DOR of 2586 days at costs of $212,485, compared to 2778 days for BR followed by LO, at a total sequence costs of $796,695. Conclusion: The use of Y90-IT in Consolidation or Second Line treatment demonstrated desired patient outcomes at one of the lowest cost profiles. Additionally, Y90-IT administration can be completed in only two clinic visits, reducing patient travel and contact, improving safety in an era of COVID-19 precautionary measures and reducing cost.

To assess the efficacy of radioimmunotherapy (RIT) with 90yttrium-ibrutinib-tiuxetan (90Y-IT) in mantle cell lymphoma, data from 90 patients registered in the RIT Network with a median follow-up (FU) of 5.5 years after RIT were evaluated. 90Y-IT was given as first-line therapy in 45 (50%) (consolidation 44 pts., primary therapy 1 pt.) and at relapse in 45 (50%) patients (consolidation 24 pts., recurrence 12 pts., therapy refractory 3 pts., conditioning 2 pts., other 4 pts.). As a first-line treatment, 30 patients (pts.) (67%) achieved CR, 10 pts. (22%) PR%., 1 pt. (2%) PD, and for 4 pts. (9%) no response data was available. At relapse, CR was achieved in 17 pts. (38%), PR in 6 pts. (13%), SD in 2 pts. (4%), and 6 pts. (13%) had PD, while the response was not documented for 14 pts. (31%). After a median FU of 5.5 years, median PFS for all patients was 2.11 (95%CI: 1.03-2.32) years, and median OS was 4.05 (95%CI 2.79-7.21) years. Eleven pts. (12.2%) developed second malignancy. In conclusion, this is the largest report of MCL pts. treated with 90Y-IT to date. 90Y-IT was most often used as consolidation after first- and second-line chemotherapy and may improve the results achieved using chemoimmunotherapy alone. However, the results are less encouraging compared to treatment with small molecules such as ibrutinib.

Introduction: Obinutuzumab (GA101; G), a fully humanized, glycoengineered, type II anti-CD20 monoclonal antibody, is approved in the US for the first-line (1L) treatment of follicular lymphoma (FL). Despite the superior efficacy of G plus chemotherapy (G-chemo) versus rituximab (R) plus chemotherapy (R-chemo) in patients with previously untreated FL demonstrated in the Phase III, randomized GALLIUM study (NCT01332968; Marcus et al. N Engl J Med 2017), information on healthcare resource use (HRU) and real-world costs with G in previously untreated FL patients is limited. The aim of this retrospective cohort study was to examine HRU and costs for G-based and R-based therapies for the 1L treatment of FL using a US claims database. Methods: The data source for this study was the PharMetrics Plus Commercial Claims database. Adult patients (≥18 years) diagnosed with FL between February 1, 2015 and September 30, 2018 and who began any treatment for FL between February 1, 2016 and September 30, 2018 were included. The first FL treatment date within this selection window was denoted the index date. Patients were required to have ≥12 months of pre-index and ≥3 months of post-index continuous study enrolment, and to have at least one FL diagnosis on or during the 12-month pre-index period. Patients with FL treatment during the 12-month pre-index period were excluded in order to select only previously untreated patients. HRU and cost data during the 1L treatment period were descriptive and categorized by HRU category. Costs are in 2018 US dollars ($) and standardized as per patient per month (PPPM) costs. FL treatment determination was based on National Comprehensive Cancer Network guidelines. Results: A total of 1584 FL patients with ≥3 months follow up were analyzed. Overall, 26 patients received G-chemo (any combination) as their 1L treatment, 208 patients received R-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone), 391 patients received R-Benda (bendamustine) and 17 patients received R-CVP (cyclophosphamide, vincristine, prednisone); the remaining 942 patients received other regimens (predominantly other R combinations). Data are reported for those patients who received G-chemo, R-CHOP, R-Benda or R-CVP as 1L therapy (n=642; 281 females, 361 males). Baseline patient characteristics were similar for most variables across treatment groups. Mean (standard deviation [SD]) age was 56.9 (9.7) years and all patients had a Charlson Comorbidity Index (CCI) of ≥2 (mean [SD]: 2.9 [1.9]). Mean (SD) patient follow-up was 14.1 (8.0) months and mean (SD) duration of 1L treatment was 7.0 (5.1) months. A summary of all-cause HRU in patients receiving 1L treatment is provided by treatment category (Figure 1A). The proportion of patients with at least one hospitalization was highest with R-CHOP (23.6%). The proportion of patients with at least one emergency room (ER) visit was highest with R-Benda (29.4%). Mean (SD) total all-cause healthcare costs PPPM during 1L treatment were comparable among G-chemo, R-CHOP and R-Benda (Figure 1B) and lowest with R-CVP ($17,874 [$13,465]). Medical costs (mean [SD]) were highest for R-Benda ($27,716 [$19,610] PPPM) and lowest for R-CVP ($17,373 [$12,908] PPPM). G-chemo was associated with the lowest pharmacy costs ($76 [$107] PPPM) (Figure 1B). Mean (SD) total cost of FL drug treatment PPPM was $16,028 ($9,942) for G-chemo, $11,684 ($6,122) for R-CHOP and $12,108 ($8,794) for R-CVP. Mean (SD) total cost of FL drug treatment PPPM was highest with R-Benda ($21,263 [$15,328]). G-specific drug costs PPPM ($9,643 [$6,071]) were similar to R-specific drug costs ($9,992 [$5,234] R-CHOP; $9,083 [$5,859] R-Benda; and $10,702 [$7,717] R-CVP). Conclusions: Our results depict real-world HRU and costs associated with G and commonly used 1L regimens for FL. In this setting, HRU and costs associated with G-chemo were comparable with R-chemo, supporting the use of G-chemo as a treatment option for patients with previously untreated FL. The study findings are limited by the small sample size of the G-chemo patient cohort (n=26) and short follow-up; to address this, an updated analysis incorporating a larger number of patients is planned.

e19536 Background: Current real-world data on healthcare utilization (HCU) and costs of common first-line (1L) follicular lymphoma (FL) regimens, including obinutuzumab (G), remain limited. The aim of this study was to examine real-world HCU and costs for the most common National Comprehensive Cancer Network (NCCN)-recommended 1L FL treatments. Methods: This was a retrospective cohort study using administrative claims data from the IQVIA PharMetrics Plus and IBM MarketScan Commercial and Medicare Supplemental databases. We identified patients (pts) ≥18 years, who had ≥1 inpatient claim or ≥2 outpatient claims, with a diagnosis of FL from February 1, 2015 to March 31, 2020, and had received 1L FL treatment (per NCCN guidelines) between February 1, 2016 and September 30, 2019. The first claim for FL treatment was the index date. All pts had ≥12 months of pre- and ≥6 months of post-index continuous enrollment in medical and pharmacy benefits. Pts with other primary cancers, FL treatment, or stem cell transplant during the pre-index period, and clinical trial participation or end-stage renal disease during the study period were excluded. All-cause HCU and costs (2020 USD) per pt during the 6-month post-index period were reported for the five most common 1L FL regimens (only complete NCCN regimens were considered). Results: Overall, 1991 pts met the eligibility criteria, and 53% were male. The mean (standard deviation [SD]) age and Charlson Comorbidity Index at index were 58 (10.4) years, and 1.7 (1.0), respectively. The most common 1L regimens were rituximab-bendamustine (R-benda; n=818 [41.1%]), R-monotherapy (R-mono; n=592 [29.7%]), R-CHOP (n=461 [23.2%]), G-benda (n=86 [4.3%]), and R-CVP (n=34 [1.7%]). The proportion of pts who had ≥1 hospitalization or an emergency room visit was highest with R-CHOP (26.7% and 33.6%, respectively) and lowest with R-mono (11.3% and 18.1%, respectively). Mean (SD) all-cause total healthcare costs were highest with R-benda and G-benda, followed by R-CHOP, R-CVP, and R-mono (Table). Mean (SD) all-cause medical and FL treatment costs (drug and administration) were highest for R-benda ($174,407 [$110,520]; $135,520 [$96,492]) and lowest for R-mono ($87,368 [$83,910]; $54,271 [$40,433]). Conclusions: This real-world study provides an update on HCU and costs among pts initiating current NCCN-recommended 1L treatment for FL. Unadjusted 6-month total healthcare costs were highest with R-benda, followed by G-benda, while the lowest costs were seen with R-CVP and R-mono. Future studies with adjustment for pt characteristics are needed to compare HCU and costs between FL regimens.[Table: see text]

Abstract Lenalidomide is an immunomodulatory drug approved in the United States for use with rituximab in patients with relapsed/refractory follicular lymphoma. We reviewed data from trials addressing the safety and efficacy of lenalidomide alone and in combination with rituximab as a first-line therapy and as a treatment of patients with relapsed/refractory follicular lymphoma. Lenalidomide-rituximab has been demonstrated to be an effective chemotherapy-free therapy that improves upon single-agent rituximab and may become an alternative to chemoimmunotherapy.
