P685Hereditary transthyretin amyloidosis is associated with significant disease burden: analysis of the baseline characteristics of patients from the phase 3 study NEURO-TTR

Background: Gilteritinib is approved for patients (pts) with relapsed/refractory (R/R) FLT3-mutated acute myeloid leukemia (AML), based on findings from the phase 3 ADMIRAL trial (Perl AE, et al. N Engl J Med. 2019). A phase 3 trial, QuANTUM-R, demonstrated the benefit of quizartinib in pts with R/R AML with FLT3 internal tandem duplication (FLT3-ITD) mutations (Cortes JE, et al. Lancet Oncol. 2019). Although eligibility criteria across both studies were similar, QuANTUM-R was more stringent as to prior therapy intensity and remission duration, which potentially enriched for higher-risk pts. We sought to describe outcomes from ADMIRAL among pts who otherwise met eligibility for QuANTUM-R. Methods: In this post-hoc analysis, a subset of pts from ADMIRAL were matched with R/R FLT3-ITD+ AML pts from QuANTUM-R on the basis of baseline characteristics and prior treatment criteria. Matched pts were either refractory to initial anthracycline-based chemotherapy or had relapsed ≤6 mos after achieving composite complete remission (CRc) with an anthracycline-based regimen. Results: Overall, 218 pts with R/R FLT3-ITD+ AML in the ADMIRAL trial (gilteritinib, n=140; salvage chemotherapy [SC], n=78) were matched with the QuANTUM-R intention-to treat (ITT) population (N=367; quizartinib, n=245; SC, n=122). Proportions of pts preselected for high-intensity SC were 66% (n=143/218) in the matched ADMIRAL ITT population and 77% (n=281/367) in the QuANTUM-R ITT populations. Demographic and baseline characteristics of the matched ADMIRAL ITT population and QuANTUM-R ITT population were similar. Median durations of exposure to gilteritinib and quizartinib were 3.8 mos and 3.2 mos, respectively, and median number of treatment cycles received were five and four, respectively. Rates of hematopoietic stem cell transplantation (HSCT) were similar in pts treated with gilteritinib (35%; n=49/140) or quizartinib (32%; n=78/245), as were the proportions of pts who resumed gilteritinib (23%; n=32/140) or quizartinib (20%; n=48/245) therapy post-HSCT. Median overall survival (OS) in pts treated with gilteritinib or quizartinib was longer than that observed with SC. After a median follow-up of 17.4 mos, median OS was 10.2 mos with gilteritinib versus 5.6 mos with SC (hazard ratio [HR]=0.573 [95% CI: 0.403, 0.814]; one-sided nominal P=0.0008). After a median follow-up of 23.5 mos, median OS with quizartinib was 6.2 mos versus 4.7 mos with SC (HR=0.76 [95% CI: 0.58-0.98]; one-sided P=0.02). After censoring for HSCT, median OS was 9.3 mos with gilteritinib versus 5.5 mos with SC (HR=0.525 [95% CI: 0.356-0.775]; nominal one-sided P=0.0005), and 5.7 mos versus 4.6 mos with quizartinib versus SC, respectively (HR=0.79 [95% CI: 0.59, 1.05]; one-sided P=0.05). In both QuANTUM-R and matched ADMIRAL populations, the survival benefits of quizartinib and gilteritinib compared with SC were maintained across multiple subgroups, including high FLT3-ITD allelic ratio subsets. Compared with SC, high CRc rates were observed in pts treated with either gilteritinib (57%; n=80/140) or quizartinib (48%; n=118/245). The complete remission (CR) rate with gilteritinib was 23% (n=32/140), whereas the CR rate with quizartinib was 4% (n=10/245) (Table). Median time to achieve CRc was 1.8 mos with gilteritinib and 1.1 mos with quizartinib, median duration of CRc was 5.5 mos with gilteritinib and 2.8 mos with quizartinib. The safety profiles of gilteritinib and quizartinib were generally similar, though aspartate or alanine aminotransferase elevations (any grade) were more frequent with gilteritinib (41-44%) than quizartinib (≤13%), whereas neutropenia (14% vs 34%, respectively), fatigue (24% vs 39%, respectively), and prolonged QT intervals (9% vs 27%, respectively) were more frequent with quizartinib. Conclusions: In pts with R/R FLT3-ITD+ AML and similar baseline characteristics, both gilteritinib and quizartinib were generally well tolerated and associated with improved survival and treatment response compared with SC. Responses to gilteritinib and quizartinib, as measured by CRc, were similar; blood count recovery varied between the two FLT3 inhibitors. Although cross-study comparisons have substantial limitations, the findings suggest that while remission is achieved faster with quizartinib, response may be more durable and survival potentially longer with gilteritinib.

Subsequent Onset

Rheumatoid arthritis (RA) is associated with a significant disease burden and high costs for society. Because the disease has identifiable preclinical stages, screening and prevention have become a possibility in RA. Anticitrullinated peptide antibodies (ACPAs) are arguably the most likely candidate biomarker to screen for RA. This paper reviews the evidence for the use of ACPAs as a screening test in the broader general population, to identify individuals at high risk of subsequent onset of RA. We will review the diagnostic properties of the test and its positive and negative predictive value in different settings. We will discuss how ACPA testing could effectively be integrated in a broader screening strategy for RA.

499 Background: Cabozantinib (C) inhibits tyrosine kinases including VEGFRs, MET, and AXL. The METEOR phase 3 trial (NCT01865747) met its primary endpoint of significant improvement in PFS with C versus everolimus (E) in pts with advanced clear cell RCC and prior exposure to VEGFR TKIs (7.4 mo median PFS [C] vs 3.8 mo [E], HR = 0.58, 95% CI, 0.45 to 0.75; p < 0.001). The improvement in PFS was accompanied by a significant improvement in ORR and a trend for improved OS at an interim analysis. Safety profiles of C and E in this trial were similar to prior experience with each drug in this pt population. This analysis further evaluates PFS and ORR across pt subgroups. Methods: Pts had advanced RCC with clear cell component, measurable disease per RECIST 1.1, KPS ≥ 70%, and were stratified by MSKCC prognostic criteria and number of prior VEGFR TKIs. Pts must have progressed during treatment or within 6 months of the last dose of their most recent VEGFR TKI. 658 pts were randomized 1:1 to receive C (60 mg QD) or E (10 mg QD). The primary endpoint was PFS among the first 375 pts randomized. ORR was a secondary endpoint. Results: In the PFS group, 187 pts were randomized to C and 188 to E. 73% pts had 1 and 27% pts ≥ 2 prior VEGFR TKIs; 43% pts had favorable, 41% intermediate, and 15% poor risk by MSKCC criteria. Across multiple subgroups defined by baseline characteristics, PFS HRs favored C over E. PFS HRs were similar for subgroups defined by prior number of TKIs (HR = 0.56 [1 prior] and 0.67 [ ≥ 2 prior]), and showed higher activity of C over E in pts with fewer MSKCC risk factors (HR = 0.54 [0 factors], 0.56 [1 factor], 0.84 [ ≥ 2 factors]) or with metastases in various organs (HR = 0.47 [lung mets], 0.53 [liver mets], 0.50 [bone mets]). Detailed analysis of the clinical activity of C and E (PFS and ORR) across pt subgroups will be presented, including treatment duration with first VEGFR TKI ( < or ≥ 6mo), receipt of prior anti-PD1/PDL1 agents, time to progression after most recent TKI ( < or ≥ 3mo), and frequency/location of metastases. Conclusions: The METEOR trial met its primary endpoint of improved PFS, and subgroup analyses of the endpoints PFS and ORR generally favored C over E in patients with advanced RCC. Clinical trial information: NCT01865747.
