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.

Abstract Background Background: Antibiotic resistance is a major public health concern. A modifiable intervention is outpatient antibiotic stewardship. The goal of this study was to review the electronic health records (EHR) of children diagnosed with community acquired pneumonia (CAP) to compare patients who received non-guideline concordant therapy with those prescribed recommended therapy. Methods Methods: This was a retrospective chart review of 300 children (6 months to 6 years old) with an outpatient diagnosis of CAP between July 2017 and June 2019. 45 Children’s Hospital of Pittsburgh (CHP) and UPMC Children’s Community Pediatrics (CCP) practices were included. CHP practices are academic-based with trainees involved in visits, while CCP practices do not include trainees. First-line recommended therapy was defined as amoxicillin, second-line therapy as azithromycin or amoxicillin-clavulanate, and all other prescriptions were defined as other. Patients prescribed first-line therapy were compared to patients with second-line therapy or other. If first-line therapy was not prescribed, the EHR was manually reviewed for justification. If drug allergy was listed, the medication allergy and type of reaction were recorded. Results Results: In this study the minority of children (43%) were prescribed first-line therapy. This group was younger (57 vs. 63 months of age), more likely to be Non-white (80%), and seen at the CHP locations than those prescribed non-guideline concordant therapy. The average symptom duration was shorter, heart rate and respiratory rate were higher and the presence of fever was more common in the first-line therapy group. Justification for non-guideline therapy was most often reported as to provide coverage for atypical organisms. The most common drug allergy recorded was amoxicillin, and urticaria with unknown timing was the most common type of reaction. Demographics Comparison Results Justification for Second-line / Other Therapy and Drug Allergy Results Conclusion This project observed a high proportion of children being prescribed non-guideline concordant therapy for a diagnosis of CAP. Age, race, practice location, and severity of illness measures showed a statistically significant difference between groups. This study highlights the importance of education which reviews the current guidelines and the most likely pathogens for children with CAP. Disclosures All Authors: No reported disclosures

Purpose Fluorouracil (FU)-leucovorin (LV), irinotecan, and oxaliplatin administered alone or in combination have proven effective in the treatment of advanced colorectal cancer (CRC). Combination protocols using FU-LV with either irinotecan or oxaliplatin are currently regarded as standard first-line therapies in this disease. However, the importance of the availability of all three active cytotoxic agents, FU-LV, irinotecan, and oxaliplatin, on overall survival (OS) has not yet been evaluated. Materials and Methods We analyzed data from seven recently published phase III trials in advanced CRC to correlate the percentage of patients receiving second-line therapy and the percentage of patients receiving all three agents with the reported median OS, using a weighted analysis. Results The reported median OS is significantly correlated with the percentage of patients who received all three drugs in the course of their disease (P = .0008) but not with the percentage of patients who received any second-line therapy (P = .19). In addition, the use of combination protocols as first-line therapy was associated with a significant improvement in median survival of 3.5 months (95% CI, 1.27 to 5.73 months; P = .0083). Conclusion Our results support the strategy of making these three active drugs available to all patients with advanced CRC who are candidates for such therapy to maximize OS. In addition, our findings suggest that, with the availability of effective salvage options, OS should no longer be regarded as the most appropriate end point by which to assess the efficacy of a palliative first-line treatment in CRC.

Abstract Background FOLFOXIRI plus bevacizumab is used as a first-line therapy for patients with unresectable or metastatic colorectal cancer. However, there are no clear recommendations for second-line therapy after FOLFOXIRI plus bevacizumab combination. Here, we describe our planning for the EFFORT study to investigate whether FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for mCRC. Methods EFFORT is an open-label, multicenter, single arm phase II study to evaluate whether a FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for mCRC. Patients with unresectable or metastatic colorectal cancer who received FOLFOXIRI plus bevacizumab as a first-line therapy will receive aflibercept and FOLFIRI (aflibercept 4 mg/kg, irinotecan 150 mg/m2 IV over 90 min, with levofolinate 200 mg/m2 IV over 2 h, followed by fluorouracil 400 mg/m2 bolus and fluorouracil 2400 mg/m2 continuous infusion over 46 h) every 2 weeks on day 1 of each cycle. The primary endpoint is progression-free survival (PFS). To achieve 80% power to show a significant response benefit with a one-sided alpha level of 0.10, assuming a threshold progression-free survival of 3 months and an expected value of at least 5.4 months, we estimated that 32 patients are necessary. Secondary endpoints include overall survival, overall response rate, safety, and exploratory biomarker analysis for differentiating anti-VEGF drug in 2nd-line chemotherapy for unresectable or metastatic colorectal cancer. Discussion This is the first study to investigate whether FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for unresectable or metastatic colorectal cancer. Switching to a different type of anti-VEGF drug in second-line therapy after FOLFOXIRI plus bevacizumab appears to be an attractive treatment strategy when considering survival benefit. It is expected that this phase II study will prove the efficacy of this strategy and that a biomarker for drug selection will be discovered.

Abstract Introduction: There is no standard of care for first-line therapy of low-grade FL. In US practice, the most common strategy is rituximab with combination chemotherapy. However, the optimal choice of regimen remains controversial; options include RCVP, RCHOP and R-Fludarabine-based chemotherapy (RFlu). Because data from randomized clinical trials are not available and unlikely to be generated in the future, we performed a decision analysis comparing RCVP, RCHOP, and RFlu as first-line therapy for FL. Methods: We constructed a Markov model of sequential first- and second-line therapy based on prescribing patterns in the US. The endpoint of the model was quality-adjusted time to tertiary referral for therapy such as RIT or autologous transplant (≥3rd line). A literature review was performed of the Medline database and international meeting abstracts. Clinical trials of both untreated and previously treated patients were systematically evaluated using explicit eligibility criteria. Data were extracted regarding response rates, treatment-related mortality, and progression-free survival (PFS). Weighted estimates were obtained using a fixed effects meta-analysis. The model also incorporated published data on heath state utilities, risk of anthracycline cardiotoxicity and fludarabine-related delayed cytopenias. Primary and sensitivity analyses were performed using TreeAge software. Results: The optimal treatment strategy consisted of RCHOP in first-line followed by RFlu in second-line (9.0 quality-adjusted life years; QALYs). Strategies containing RCVP in either first- or second-line were inferior (6.2–7.7 QALYs). The model was sensitive to first-line PFS of RCHOP and RFlu when these were varied over the range of estimates obtained from individual published trials. The model was robust in sensitivity analysis of most other parameters, including rate of delayed cytopenias after RFlu, anthracycline cardiotoxicity, and quality of life adjustments. Conclusions: Using decision analysis, the optimal first-line therapy for low-grade FL is RCHOP, followed by RFlu in second-line. This strategy maximizes quality-adjusted time to tertiary therapy. Use of RCVP does not improve overall quality-adjusted time relative to more intensive therapies.

Abstract Abstract 1796 Introduction: FCR chemoimmunotherapy is recommended as first line therapy for fit cll patients. Since the 2007 EBMT guidelines based on the previously published trials using FCR, the definition of high risk CLL has evolved, to include biologic parameters (TP53 disruption by deletion/mutation, high b2-microglobulin level, IgVH unmutated, complex karyotype), refractoriness (progression during fluda-based regimen or within 6mo of completion), and also remission duration (high risk if PFS after FCR <24mo, ultra-high risk if TTNT <24–36mo with TP53 del/mut). However, few data are available regarding the characteristiscs, response rate and outcome of CLL patients treated in second line after FCR first line. Patients and methods: In this multicentric retrospective study, we collected data from 117 patients who relapsed after FCR first line therapy and received second-line therapy (according to NCI2008 guidelines). Results: At the time of initial FCR therapy: patients characteristics were as follows: Binet B/C 87.2%, unmutated IgVH 52.2%, del11q 25.6% (n=30/81 with FISH available), del17p 6.8% (n=8/87 with FISH available), bulk>5cm 22%, complex karyotype 21% (n=12/57 with karyotype available). FCR yielded 93% ORR, with 66% clinical CR, 27% PR, and 7% failed to respond. Median PFS and TTNT were 27mo and 32.5mo, respectively. At the time of relapse: patients characteristics were as follows: del11q 16.4% (n=19/65 with FISH available), del17p 19% (n=22/77), bulk>5cm 26%, complex karyotype 44% (n=24/54 with karyotype available). According to FCR remission duration, 11.1% of patients were considered as truly FCR-refractory, 47% had PFS<24mo, 34.2% had TTNT<24mo. TTNT<24mo after FCR was correlated to age>65y, del17p (20% vs 0%) and complex karyotype (38% vs11%), but not with gender, IgVH status, del11q, or bulk>5cm. Based on FCR-refractoriness, or TTNT<24mo and/or del17p, 53 patients were considered as ultra-high risk (45.3%). Various regimen were used for second-line treatment after FCR: R-bendamustine (n=47, 40.2%), alemtuzumab-based therapy (single agent or with chemo/dexa, n=22, 18.8%), R-CHOP (n=15, 12.8%), FCR (n=14, 12%), and other miscellaneous regimens (as follows: R-alkylator (n=6, 5.1%), R-DHAP (n=4, 3.4%), R-methylprednisolone (n=3, 2.6%), or investigational drugs (n=6, 5.1%)). Thus, 74.3% of patients received a second course including rituximab-based chemotherapy. Overall response rate was 78.4%, with 13.8% clinical CR, 64.6% PR, and 21.6% failure/stable disease. 14 pts (12%) underwent stem cell transplantations, 8 had maintenance therapy ongoing (ofatumumab, alemtuzumab, or lenalidomide). With regards to factors defining high-risk relapse, distribution of salvage therapies was as follows: As expected, a second course of FCR was seldom used in high-risk patients. Among ultra-high risk patients, 30.3% received R-benda, 11.3% Alem-based Rx, 32% R-CHOP and 18% the miscellaneous regimens described above. After second-line therapy, median PFS was 12 months, median TTNT was 14mo, and median OS was 36mo (20 deaths). On univariate analysis, complex karyotype (p=0.04) but not del17p (p=0.1), PFS<24mo (p=0.028) and TTNT<24mo (p=0.04) correlated with OS. Regarding treatment, OS was significantly improved in R-bendamustine-treated patients, as compared to alem-based or CHOP regimen (p=0.01). Most importantly, patients who received an allogeneic transplant benefited from significantly prolonged OS (at 4y, 70% vs 40%, p=0.03). Of note, only one patient treated with R-benda received allotransplant. Conclusions: This study shows that there are no consensus for second line therapy after FCR. Second line trials after FCR therapy are warranted. Definition of high-risk subsets of patients at relapse after FCR is of upmost importance in the management of CLL, to compare second-line strategies. Our data suggest that R-bendamustine is an efficient regimen even in high-risk patients (complex karyotype, PFS<24mo, TTNT<24mo). These data are important since this immunochemotherapy is now used as the backbone for combination with new compounds (ibrutinib, GS1101, GDC-199). Disclosures: Aurran-Schleinitz: Roche: Honoraria.

Abstract Introduction Lenalidomide (LEN) is the standard of care for treatment of transfusion dependent lower risk myelodysplastic syndromes (MDS) with chromosome 5q deletion (del 5q). In the MDS-002 study, 26% of lower risk transfusion dependent MDS patients became red blood cell transfusion independent after LEN treatment. National Comprehensive Cancer Network (NCCN) clinical guidelines list LEN as a second line treatment alternative for transfusion dependent anemia in lower risk non-del 5q MDS after azanucleosides failure. The response rate to LEN after azanucleosides failure, however, is not known given that the MDS-002 study preceded FDA approval of azanucleosides. To address the best sequence of LEN to optimize response potential in lower risk MDS, we examined the response rates to LEN in non-del 5q lower risk MDS when offered as first line after (erythroid stimulating agents) ESA's or after azacitidine failure. Methods This was a retrospective study conducted using the Moffitt Cancer Center (MCC) MDS database. We identified patients with lower risk MDS who received both LEN and azacitidine as first or second line therapy after erythroid stimulating agents. Lower risk MDS was defined according to the international prognostic scoring system (IPSS) Low or intermediate-1 (int-1) risk groups. The primary endpoint was to compare rates of erythroid hematological improvement (HI-E) between the group of patients who received LEN as first line therapy followed by azacitidine as second line (LEN 1st line group) and those who received LEN as second line therapy after azacitidine (LEN 2nd line group). HI was defined according to international working group criteria (IWG 2006). Chi- square test was used for categorical variables, T-test was used for continuous variables, and Kaplan Meier estimates for overall survival. All analyses were conducted using SPSS statistical software (IBM version 21) Results We identified 63 patients who received both azacitidine and LEN as first and second line where 37 patients were in group 1 (LEN 1st line) and 26 patients were in group 2 (LEN 2nd line). Baseline characteristics between the two groups are summarized in Table-1. There were no statistically significant differences between the 2 groups in terms of mean age at diagnosis, gender, WHO subtype, revised IPSS, or mean blood counts. The majority of patients had refractory cytopenia with multilineage dysplasia (RCMD) and had low risk revised IPSS . The rate of HI-E was 38% (n=14) among LEN 1st line group compared to 12% (n=3) in LEN 2nd line group. (p=0.04). There was no difference in overall survival (OS) among the two groups with a median OS of 104 months and 87 months, respectively, p=0.55. There was no difference in AML transformation rate, 5.4% (n=2) and 11% (n=3) among the two groups, respectively, p=0.33. There were no differences in response rates to azacitidine among the two groups. Among the Len 1st line group response to 2nd line azacitidine was 38% (n=14) compared to 35% (n=9) among those who received azacitidine as first line followed by LEN as 2nd line. (p=0.69). Conclusion LEN yields a higher rate of HI-E in non-del 5q lower risk MDS when used as first line therapy. If validated in a larger cohort, LEN should be considered for 1st line therapy after ESAs rather than after azacitidine failure. Responses to azacitidine were similar among the two groups, indicating no adverse effect of LEN on azacitidine response. Disclosures: Komrokji: Celgene: Research Funding, Speakers Bureau.

641 Background: Bevacizumab provides survival benefit as the first-line and second-line therapies in metastatic colorectal cancer (mCRC). A large observational study suggested use of bevacizumab beyond first progression (BBP) improved survival. This prompted us to conduct a multicenter phase II study of mFOLFOX6 plus bevacizumab followed by FOLFIRI plus bevacizimab in mCRC to further explore the strategy of BBP in Japanese patients. Methods: Previously untreated patients with assessable disease were treated with mFOLFOX6 plus bevacizumab until tumor progression, followed by FOLFIRI plus bevacizumab. The primary endpoint of the study was the second progression-free survival (2nd PFS), defined as duration from enrollment until progression after the second-line therapy. If the patient failed to receive the second-line treatment due to medical reasons or refusal, the PFS during the first-line therapy was used for analysis. Secondary endpoints were PFS, overall survival (OS), response rate (RR), disease control rate (DCR) and safety. Results: In the first-line therapy, 47 patients treated with mFOLFOX6 plus bevacizumab achieved RR of 61.7%, DCR of 89.4% and median PFS of 11.7 months. Thirty patients went on to receive the second-line therapy with FOLFIRI plus bevacizumab and achieved RR of 27.6%, DCR of 62.1%, and median PFS of 6.0 months. Median 2nd PFS was 16.2 months. Median survival time did not reach the median follow-up time of 27.4 months. Severe adverse events associated with bevacizumab during the first-line therapy were a venous thromboembolic event in one case (2%), a grade 2 bleeding event in one case (2%) and GI perforation in one case (2%). However, no critical events associated with bevacizumab were reported during the second-line therapy. Conclusions: The planned continuation of bevacizumab during the second line treatment is feasible in Japanese mCRC patients. A prospective randomized control study to confirm the efficacy has to be conducted in the future.

421 Background: The options for treatment of pancreatic cancer follow progression on first line therapy are limited and associated with significant toxicity. Erlotinib has been approved for treatment of pancreatic cancer in first-line therapy. We conducted a phase I dose-escalation trial of erlotinib in combination with gemcitabine for patients that had failed first-line therapy. Erlotinib was administered by a novel pulse-dose schedule where the drug was given orally for 3 days every two weeks. Purpose: Assess the safety and determine a recommended phase II dose for pulsed high dose erlotinib in combination with gemcitabine for pancreatic cancer, and obtain preliminary data on activity. Methods: Patients with pancreatic cancer that progressed on or after first-line therapy were treated in a dose escalation study with erlotinib at 750 to 2,000 mg daily for three days every two weeks in combination with weekly gemcitabine at 1,000 mg/m2 for three weeks on and one week off. Results: No dose limiting toxicities were encountered and erlotinib-induced rash was mild and transient. Median overall survival was 6.7 months and 12-month overall survival was 27%. Progression free survival but not overall survival was longer in patients who did not previously receive gemcitabine. Rash was not associated with longer survival. Conclusions: The recommended phase II dose is erlotinib 2,000 mg daily for three consecutive days every two weeks in combination with gemcitabine. Tolerability was excellent, and outcomes were better than expected for second-line therapy in pancreatic cancer. Further studies are warranted, both as therapy after first-line and as first-line therapy for patients unable to tolerate more aggressive regimens. Clinical trial information: NCT02154737.

TPS4151 Background: Platinum/fluoropyrimidine regimens are the backbone of first-line therapy for advanced gastric cancer (AGC). The optimal duration of first-line therapy is still unknown and its continuation until disease progression represents the standard. However this strategy is often associated with cumulative toxicity and rapid development of drug resistance. Moreover, only 40% of AGC pts are eligible for second-line treatment. This study aims at assessing whether switch maintenance to ramucirumab plus paclitaxel will extend the progression-free survival (PFS) of subjects with HER-2 negative AGC who have not progressed after a first-line with a platinum/fluoropyrimidine regimen. The hypothesis is that the early administration of an active, non-cross resistant regimen may delay disease progression and, consequently, improve pts’ quality of life. This strategy may also rescue all those subjects that become ineligible for a second-line therapy due to the rapid clinical deterioration. Methods: This is a randomized, open-label, multicenter, phase III trial. Eligibility criteria are: unresectable/metastatic HER-2 negative AGC or gastroesophageal junction (GEJ) cancer; ECOG PS 0-1; measurable and/or evaluable disease by RECIST v1.1; no progression after 3 months of therapy with either FOLFOX4, mFOLFOX6 or XELOX . The primary endpoint is to compare PFS of pts in ARM A (continuation of the same first-line therapy with oxaliplatin/fluoropyrimidine) versus ARM B (switch maintenance to ramucirumab and placlitaxel). Secondary endpoints are: overall survival, time-to-treatment failure, overall response rate, duration of response, percentage of pts receiving a second-line therapy per treatment arm, safety and quality of life. Exploratory analyses to identify primary resistance and prognosis biomarkers are planned, including Next-Generation Sequencing (NGS) on archival tumor tissues. The ARMANI study is sponsored by the Fondazione IRCCS Istituto Nazionale dei Tumori and it is ongoing at 29 Italian centers with a planned population of 280 pts.
