    Abstract: 629 Background: Nearly all mRCC pts will be treated with one or more VEGFR TKI, alone or in combination with an immunotherapy (IO) or mTOR-inhibitor, during their therapeutic journey and may experience associated AEs. Evidence from the tivozanib (tivo) TIVO-3 trial suggests that median duration of clinically relevant VEGFR TKI class effect AEs is ≤90 days (range 14-90). Cost of AE management has not been clearly quantified to date. This study aimed to estimate how differences in TKI AE profile may impact treatment cost efficiency, particularly in later line (3L+) settings. Methods: iKnowMed EMR was used to identify mRCC pts from USON or Onmark Network, with matched 3 rd party insurance claims, that initiated VEGFR TKI treatment between Jan 2015 and Mar 2021. First occurrence of each VEGFR TKI class effect AE was indexed, and associated costs for 90-day (longest median AE duration) follow-up was captured. To assess burden across different TKIs, average per-patient AE management cost was calculated using incidence data from trials supporting FDA approvals, and weight-adjusted to estimated number of commercially insured 3L/4L pts in a 1,000,000-member plan. Results: 5,958 mRCC pts were identified, of which 4,464 were on at least one TKI regimen. Among those, 1,777 experienced an index AE; 1,072 successfully matched to claims data [median 69 years (range 25-94); 55% ECOG PS 0/1; 69% male], accounting for 1,667 unique index AE cases. Most were on cabozantinib (cabo), axitinib (axi), or pazopanib; lenvatinib (len), sunitinib (sun), and sorafenib were also represented. 〉 80% were TKI only, with the rest TKI+IO (18%) or TKI+mTOR (6%). AE costs largely originated from outpatient visits (range 38-77%), excluding renal failure (58% inpatient). Mean cost per AE ranged from $76 (proteinuria) to $1,687 (mucositis/stomatitis). Overall, estimated costs of managing VEGFR TKI class effect AEs in 3L/4L showed lowest resource burden with tivo, and highest with len+everolimus (len+ev; Table). Conclusions: Average VEGFR TKI AE management costs derived from real-world mRCC pts demonstrated differences in healthcare resource burden, with overall anticipated cost dependent on TKI regimen utilized.

    Abstract: 213 Background: The treatment of ALL involves complex chemotherapy regimens that are difficult to deliver to underserved populations. Lyndon B. Johnson General Hospital (LBJGH) provides care to uninsured and underinsured patients in Harris County, the third largest county in the United States. Our goal is to achieve 80% adherence to National Comprehensive Cancer Network guidelines in the care of newly diagnosed ALL patients at LBJGH. Methods: The charts of 14 patients with newly diagnosed ALL were reviewed. Demographics, initial work-up (e.g., bone marrow biopsy and aspirate), type of treatment, adherence to scheduled treatment, use of supportive medications, outpatient follow-up, stem cell transplant referral and quality of provider documentation were collected. Areas of potential improvement were then identified using provider focus groups and Ishikowa Diagram. The project was approved by the MD Anderson Quality Improvement Assessment Board. Results: 12/14 patients were evaluable, having received their full course of care at LBJGH. The median age was 35, 9/12 (75%) were female and 9/12 (75%) were Hispanic. 6/11 (55%) cases expressed CD20 (CD20+) and 3/11 (27%) were Philadelphia chromosome positive (Ph+). All 12 patients received induction and consolidation therapy with the HyperCVAD regimen (cyclophosphamide/vincristine/doxorubicin/dexamethasone alternating with high-dose methotrexate/cytarabine). Bone marrow biopsy at time of diagnosis, use of a tyrosine kinase inhibitor for Ph+ ALL, and use of supportive medications occurred 〉 80% of the time. Administration of outpatient chemotherapy, use of rituximab for CD20+ ALL, outpatient lab follow-up, intrathecal chemotherapy and appropriate referral for allogeneic transplant occurred 50-80% of the time. Provider documentation was appropriate 〈 50% of the time. Conclusions: Based on these findings, we established a standard algorithm of care for ALL patients at LBJGH, enhanced provider education through the design and distribution of teaching tools, created a checklist to facilitate handoffs between providers and established expectations for documentation. In the future, we would also like to add a patient navigator to further improve coordination of care.

    Abstract: There is no effective systemic therapy for metastatic adrenal cortical carcinoma (ACC) after failure of platinum-based chemotherapy. The efficacies of single-agent oral multikinase inhibitors (MKIs) or salvage immune checkpoint inhibitors (CPIs) have been very limited. It is unknown whether combining CPIs, such as pembrolizumab (PEM), with other therapies, such as MKIs, could yield higher response rates in ACC, yet this combination has shown promise in other cancers. Herein, we describe the first case series using PEM in combination with the MKI lenvatinib (LEN) in patients with progressive, metastatic ACC. Methods A retrospective case series describing the use of LEN/PEM as salvage therapy in patients with progressive/metastatic ACC. Results Eight patients were treated with the LEN/PEM combination therapy. Half were female, and the median age at time of diagnosis was 38 years (range 21–49). Three (37.5%) patients had hormonally active ACC. The median number of prior lines of systemic therapy was 4 (range 2–9). Six (75%) patients had had disease progression on prior CPIs and five (62.5%) patients had progressed on prior MKI therapy. The median progression-free survival was 5.5 months (95% CI 1.8–not reached) and median duration of therapy was 8.5 months (range 2–22). Two (25%) patients had a partial response, one (12.5%) patient had stable disease, and five (62.5%) patients had progressive disease. None of the eight patients stopped therapy because of adverse events. Conclusions In our small cohort of heavily pretreated patients with ACC, the combination of LEN/PEM was associated with objective responses in a subset of patients without significant toxicity. This combination should be formally investigated in phase II clinical trial with robust correlative studies to identify predictors for response.

    Phase II study of sitravatinib in combination with nivolumab in patients with advanced or metastatic urothelial carcinoma (UC) after checkpoint inhibitor therapy (CIT).
    American Society of Clinical Oncology (ASCO) ; 2019

    Abstract: TPS498 Background: Combination therapy with agents targeting molecular and cellular mechanisms of CIT resistance is a rational approach to restoring CIT efficacy in patients (pts) with immunotherapy-resistant UC. Sitravatinib is a tyrosine kinase inhibitor (TKI) that targets multiple closely-related receptor tyrosine kinase (RTK) pathways, including the split RTKs VEGFR-2 and KIT, as well as the TAM (TYRO3, AXL, and MER) RTKs. Inhibition of the split RTKs enhances antitumor activity by reduction of immunosuppressive regulatory T cells and myeloid-derived suppressor cells (MDSCs) within the tumor microenvironment (TME). Inhibition of TAM RTKs further restores a more immune-supportive TME by depletion of MDSCs and repolarization of tumor-associated macrophages to the M1 phenotype associated with secretion of pro-inflammatory cytokines. Given these pleiotropic immune-activating effects, the combination of sitravatinib with nivolumab is a rational approach to restoring or enhancing CIT clinical activity in pts with immunotherapy-resistant UC. This combination has been shown to be safe and tolerable in an ongoing Phase 2 study in pts with metastatic non-small cell lung cancer. Methods: This open-label Phase 2 study evaluates tolerability and clinical activity of sitravatinib in combination with nivolumab in pts with advanced or metastatic UC who experienced disease progression on or after CIT as the most recent systemic therapy. Enrollment is stratified by prior receipt of platinum-based chemotherapy. If the initial 2 cohorts are of high interest for efficacy, the protocol allows for addition of new cohorts to include pts previously treated with selected immunotherapies (anti-CTLA-4, anti-OX40 or anti–CD137 therapy) or who are CIT-naïve. The primary objective is Objective Response Rate. A Predictive Probability Design will be applied allowing for expansion to 40 pts per cohort. Sitravatinib is administered orally daily in continuous 28-day cycles at 120 mg; nivolumab intravenously at 240 mg every 2 weeks or 480 mg every 4 weeks. Status: The study is open for enrollment and recruitment is ongoing. Clinical trial information: NCT03606174.

    Abstract: 9096 Background: HD IL-2 is an approved immunotherapy that can achieve durable cures in MM pts. Due to toxicity and low ORR, identification of predictors of clinical benefit would enhance pt selection and outcomes with HD IL-2. Recent research identified a positive correlation for ALC ≥ 1000 (either at baseline or at dose 3) with OS among MM pts treated with the immunotherapy agent ipilimumab. We tested the hypothesis that ALC (≥ 1000) or other hematological parameters correlates with clinical benefit from HD IL2. Methods: Results of hematologic testing in patients (n=98) treated with HD IL2 at MD Anderson Cancer Center were collected, including absolute levels of neutrophils (ANC), lymphocytes (ALC), monocytes (AMC), eosinophils (AEC), and platelets (APC) at baseline, after cycle 1 (C1), and after cycle 2 (C2) of HD IL-2; changes in each parameter for each interval were also calculated. Hematologic values were assessed as categorical (for ALC, ≥ 1000 Yes/No; other parameters, above upper limit of normal [ULN] Yes/No) and continuous variables. Associations between these parameters and PFS and ORR were analyzed. Results: ALC was≥ 1000 in 75 pts (76%) at baseline, in 81 (83%) after C1, and in 80 of 86 pts (93%) after completion of C2 of HD IL-2. PFS was not significantly associated with ALC ≥ 1000 at baseline (HR 0.69, p=0.13), after C1 (HR 1.32, p=0.33), or after C2 (HR 1.01, p=0.98). ALC ≥ 1000 at each timepoint was not significantly associated with ORR or OS. There was no significant difference in the change in ALC with HD IL2 treatment among responders versus non-responders. Among baseline hematological factors, APC 〉 ULN was significantly associated with PFS (p=0.001), but it was rare (2/98 patients). Exploratory analyses identified significantly shorter PFS for patients with baseline APC 〉 300 (11%, HR 2.75, p=0.002). Analysis of hematologic factors as continuous values identified significant associations with PFS for AMC (HR 2.42, p=0.03) and AEC (HR 1.73, p=0.009) after C2. Conclusions: ALC ≥ 1000 did not correlate with PFS, ORR, or OS with HD IL-2 therapy in this cohort of metastatic melanoma pts.

    Abstract: 315 Background: Combination therapy with nivolumab + ipilimumab (NIVO+IPI) has demonstrated long-term efficacy and tolerability for patients (pts) with previously untreated advanced renal cell carcinoma (aRCC). Most pivotal clinical trials in pts with aRCC have excluded pts with low Karnofsky performance status (KPS; 〈 70%). CheckMate 920 is a multi-arm, phase IIIb/IV, open-label clinical trial of NIVO+IPI treatment in pts enrolled in a community practice setting with aRCC and a high unmet medical need. We present safety and efficacy results for the cohort of pts with aRCC of any histology and KPS 50%–60% from CheckMate 920 (NCT02982954). Methods: Pts with previously untreated advanced/metastatic RCC and KPS 50%–60% received NIVO 3 mg/kg + IPI 1 mg/kg Q3W × 4 doses followed by 480 mg NIVO Q4W for ≤ 2 years or until disease progression/unacceptable toxicity. The primary endpoint was incidence of grade ≥ 3 immune-mediated adverse events (imAEs) within 100 days of last dose of study drug. Key secondary endpoints included progression-free survival (PFS) and objective response rate (ORR) by RECIST v1.1 (both per investigator). Exploratory endpoints included overall survival (OS). Results: Of 25 treated pts with KPS 50%–60%, 76% were men; median age was 67 years (range, 34–81). IMDC risk was favorable in 0%, intermediate in 32%, and poor in 68% of pts; 84% had clear cell and 16% had non-clear cell RCC histology. With a minimum follow-up of 25 months, median duration of therapy (95% CI) was 2.3 months (2.1–7.7) for NIVO and 2.1 months (2.1–2.1) for IPI. The median number of doses (range) received was 4 (1–27) for NIVO and 4 (1–4) for IPI; 76% of pts received ≥ 4 NIVO doses and 68% received all 4 IPI doses. The only grade 3–4 imAEs by category were hepatitis (4.0%) and adrenal insufficiency (4.0%). No grade 5 imAEs occurred. Overall, 4 (16%) pts discontinued due to any-grade adverse events (n = 1 each for elevated AST, malignant neoplasm progression, back pain, and acetabulum fracture). Of 18 evaluable pts, ORR was 33.3% (95% CI, 13.3–59.0); no pts had a complete response and 6 had partial response. Median time to objective response was 4.5 months (range, 2.5–24.7). Median duration of objective response was 20.6 months (range, 0.03+–24.2+). Median PFS was 4.6 months (95% CI, 2.5–14.8). Median OS was 15.6 months (95% CI, 5.3–25.1). Conclusions: NIVO+IPI demonstrated an acceptable safety profile and promising antitumor activity in pts with previously untreated aRCC and KPS 50%–60%. The combination was tolerated at a dose intensity similar to that observed in clinical trials conducted in pts with higher KPS (≥ 70%). These data support the value of NIVO+IPI in pts who may not be considered ideal candidates for this therapy and consequently may have limited treatment options. Clinical trial information: NCT02982954 .
