AB0509 SUSPENSIVE EFFICACY OF TOCILIZUMAB IN TREATMENT-NAÏVE PATIENTS WITH TAKAYASU ARTERITIS: TOCITAKA FRENCH PROSPECTIVE MULTICENTER OPEN-LABELLED TRIAL.

Objectives:To assess long term efficacy of tocilizumab in treatment-naive patients with Takayasu arteritis (TAK).Methods:In this multicenter, prospective, open-labelled trial, we aim to evaluate the benefit of adding tocilizumab to steroids in treatment-naïve patients with TAK, on discontinuation of steroids after 6 months of tocilizumab treatment, and to assess relapse-free survival following tocilizumab discontinuation.Results:Thirteen patients with TAK were included, with a median age of 32 years [19-45] and 12 (92%) females. Six (54%) patients met the primary end-point. Among 11 (85%) patients which achieved remission at 6 months, 6 (54%) have reached primary endpoint.. Among the 5 remaining patients which continued steroids, 3 had a prednisone-equivalent dosage < 5mg/day. A significant decrease of disease activity was observed after 6 months of tocilizumab therapy: decrease of median NIH scale (3 [3-4] at baseline, versus 1 [0-2] after 6 months; p <0.001), ITAS-2010 score (5 [2-7] versus 3 [0-8]; p = 0.002), and ITAS-A score (7 [4-10] versus 4 [1-15]; p = 0.0001)]. All patients discontinued tocilizumab after 7 infusions, and no other immunosuppressive drugs was introduced, except for 1 patient which received methotrexate. After 9 and 12 months, respectively 7 (54%) and 6 (50%) patients achieved remission with less than 7.5 mg/day of prednisone, and 9 (69%) and 9 (75%) with doses <10 mg/day. During the 12 months follow-up after tocilizumab discontinuation, a relapse occurred among 5 patients (45%) out of 11 in which achieved remission after 6 months of tocilizumab.No severe AEs were considered related to study treatment and none required tocilizumab interruption or dose reduction. No deaths have occurred during the study period.Conclusion:Tocilizumab seems an effective steroid sparing therapy in TAK but its effect appears to be suspensive.Disclosure of Interests:Arsene Mekinian: None declared, david Saadoun: None declared, [email protected] [email protected]: None declared, [email protected] [email protected]: None declared, Patrick Jégo: None declared, [email protected] [email protected]: None declared, wxv wxv: None declared, Jacques-Eric Gottenberg Grant/research support from: BMS, Pfizer, Consultant of: BMS, Sanofi-Genzyme, UCB, Speakers bureau: Abbvie, Eli Lilly and Co., Roche, Sanofi-Genzyme, UCB, Mathieu Vautier: None declared, [email protected]>; [email protected]>;: None declared, Patrice cacoub: None declared, olivier fain: None declared

Abstract Objectives To assess long-term efficacy of tocilizumab in treatment-naive patients with Takayasu arteritis (TAK). Methods Prospective open-labeled trial in naïve patients with TAK who received steroids at the dose of 0.7 mg/kg/day and 7 infusions of 8 mg/kg/month of tocilizumab. The primary endpoint was the number of patients who discontinued steroids after 7 infusions of tocilizumab. Secondary endpoints included disease activity and the number of relapses during 18-month follow-up. Results Thirteen patients with TAK were included, with a median age of 32 years [19–45] and 12 (92%) females. Six (54%) patients met the primary end-point. A significant decrease of disease activity was observed after 6 months of tocilizumab therapy: decrease of median NIH scale (3 [3, 4] at baseline, versus 1 [0–2] after 6 months; p < 0.001), ITAS-2010 score (5 [2–7] versus 3 [0–8]; p = 0.002), and ITAS-A score (7 [4–10] versus 4 [1–15]; p = 0.0001)]. During the 12-month follow-up after tocilizumab discontinuation, a relapse occurred among 5 patients (45%) out of 11 in which achieved remission after 6 months of tocilizumab. Conclusion Tocilizumab seems an effective steroid sparing therapy in TAK, but maintenance therapy is necessary. Trial registration ClinicalTrials.gov NCT02101333. Registered on 02 April 2014.

Background:Hypertension occurred in 30-80% of TAK patients around the world. The occurrence of hypertension might severely worsen TAK prognosis. Nevertheless, data describing the specific imaging features in hypertensive TAK patients and the associations between hypertensive severity, blood pressure control status and long-term outcome were still lacking.Objectives:To investigate the characteristics and associations of hypertensive characteristics with adverse events-free survival in Takayasu arteritis (TAK) patients with hypertension.Methods:This research was based on a prospectively on-going observational cohort-East China Takayasu Arteritis (ECTA) cohort. In all, 618 TAK patients, who registered in the ECTA cohort up to December 2019, were enrolled. The main outcome was the adverse-events-free survival among hypertensive TAK patients during the follow-up ended on August 2020.Results:Totally, 204 (33.0%) patients suffered from hypertension, with 48 (23.5%), 62 (30.4%), and 94 (46.1%) mild, moderate, and severe hypertension, respectively. Cluster analysis indicated three imaging phenotypes for hypertensive TAK patients: Cluster 1: involvement of the abdominal aorta and/or renal artery (n=56, 27.5%); Cluster 2: involvement of the ascending aorta, thoracic aorta, and the aortic arch and its branches (n=38, 18.6%); Cluster 3: combined involvement of Cluster 1 and Cluster 2 (n=111, 54.4%). By the end of the follow-up, the blood pressure control rate was 50.8%, while the adverse-events-free survival was 67.9% in the entire hypertensive population. Multivariate Cox regression analysis indicated that well-controlled blood pressure (HR=2.13, 95%CI 1.32–3.78, p=0.047), co-existence of severe aortic valve regurgitation (HR=0.87, 95%CI 0.64–0.95, p=0.043), Cluster 1 (HR=0.69, 95%CI 0.48–0.92, p=0.017) and Cluster 3 (HR=0.72, 95%CI 0.43–0.94, p=0.048) imaging phenotype was associated with the adverse-events-free survival.Conclusion:Patients with controlled hypertension showed better adverse-events-free survival, while those with the Cluster 1 imaging phenotype were more likely to suffer from worse adverse-events-free survival. Hypertension occurred in 30-80% of TAK patients around the world. The occurrence of hypertension might severely worsen TAK prognosis.References:[1]Johnston SL, Lock RJ, Gompels MM.

Disease Activity Measures

Background:The primary treatment goal for patients (pts) with rheumatoid arthritis (RA) is a state of sustained clinical remission (REM) or low disease activity (LDA).1,2Objectives:To assess the long-term sustainability of responses to upadacitinib (UPA), a JAK inhibitor, with or without background csDMARD(s) in pts with RA.Methods:Data are from two phase 3 randomized, controlled trials of UPA in RA pts with roughly similar baseline disease characteristics: SELECT-NEXT enrolled pts with an inadequate response (IR) to csDMARD(s) on background stable csDMARD(s) receiving UPA 15 mg or 30 mg once daily or placebo for 12 weeks (wks); SELECT-MONOTHERAPY enrolled methotrexate (MTX)-IR pts receiving UPA 15 mg or 30 mg monotherapy or blinded MTX for 14 wks. After 12/14 wks, pts could enter a blinded long-term extension and receive UPA 15 mg or 30 mg for up to 5 years. This post hoc analysis evaluated clinical REM (CDAI ≤2.8; SDAI ≤3.3), LDA (CDAI≤10; SDAI≤11), and DAS28(CRP) <2.6/≤3.2 at first occurrence before Wk 84; additionally, these measures were evaluated at 3, 6, and 12 months after the first occurrence for the total number of pts randomized to UPA 15 mg. Sustainability of response was evaluated by Kaplan-Meier only for those pts who achieved REM/LDA and was defined as time to the earliest date of losing response at two consecutive visits or discontinuation of study drug. The predictive ability of time to clinical REM/LDA was assessed using Harrell’s concordance (c)-index (for reference, an index ~ 0.5, indicates no ability to predict; an index of 1 or -1 would be a perfect prediction). The last follow up dates were 22 March, 2018 (SELECT-NEXT) and 25 May, 2019 (SELECT-MONOTHERAPY), when all pts had reached the Wk 84 visit.Results:Through Wk 84, the percent of treated pts achieving CDAI REM/LDA was 43%/79% for those receiving UPA 15 mg with background csDMARD(s) (SELECT-NEXT) and 37%/76% for those receiving UPA 15 mg without background csDMARD(s) (SELECT-MONOTHERAPY). 35%/25% of pts randomized to UPA 15 mg with background csDMARD(s) and 27%/23% of pts randomized to UPA 15 mg without background csDMARD(s) achieved sustained CDAI REM through 6/12 months after the first occurrence. 64%/56% of pts randomized to UPA 15 mg with background csDMARD(s) and 61%/56% of pts randomized to UPA 15 mg without background csDMARD(s) achieved sustained CDAI LDA through 6/12 months after the first occurrence (Figure 1). Time to initial clinical REM/LDA did not appear to be associated with sustained disease control. The c-indices (95%CI) for CDAI REM in the UPA 15 mg with background csDMARD(s) and UPA 15 mg without background csDMARD(s) groups were 0.541 (0.47, 0.62) and 0.568 (0.49, 0.65) and that of LDA were 0.521 (0.46, 0.58) and 0.498 (0.43, 0.56), respectively. Through last follow-up visit, 55% of pts receiving UPA 15 mg with background csDMARD(s) and 62% of pts receiving UPA 15 mg without background csDMARD(s) remained in CDAI REM while 72% and 70% of pts remained in CDAI LDA, respectively (Figure 2). Similar results were observed across other disease activity measures (SDAI REM/LDA and DAS28(CRP) <2.6/≤3.2).Conclusion:More than a quarter and more than a half of pts with RA and prior IR to csDMARD(s) receiving UPA with or without background csDMARD therapy achieved sustained clinical REM and LDA, respectively, across disease activity measures. Sustainability of responses appeared comparable among pts receiving UPA with or without background csDMARDs through up to 84 wks.References:[1]EULAR: Smolen JS, et al.

Abstract Abstract 1056 Poster Board I-78 Introduction: We previously showed that a prolonged myelosuppressive maintenance chemotherapy was superior to S-HAM as a postremission therapy in patients > 16 years of age with AML after a TAD-HAM double induction therapy and TAD consolidation chemotherapy with regard to relapse-free survival (RFS) and borderline significance of the overall survival (OS) in responding patients (Buchner et al., JCO 2003, 21:4496-4504). Here we present long-term follow-up data with a median follow-up of 7.9 years from diagnosis and 7.1 years from the date of complete remission. Patients and Methods: Eight hundred thirty-two patients (median age, 54 years; range, 16 to 82 years) with de novo AML were upfront randomized in the AMLCG1992 study of the German AML Co-operative Group to receive 6-thioguanine, cytarabine, and daunorubicin (TAD) plus cytarabine and mitoxantrone (HAM; cytarabine 3 g/m2 [age < 60 years] or 1 g/m2 [age ≥ 60 years] x 6 (HAM in patients ≥ 60 years only in case of blast persistence on day 16 of therapy) induction, TAD consolidation, and monthly maintenance with cycles of cytarabine combined with either daunorubicin (course 1), 6-thioguanine (course 2), cyclophosphamide (course 3), and again 6-thioguanine (course 4), and restarting with course 1 for 3 years, or to receive TAD-HAM-TAD and one course of intensive consolidation with sequential HAM (S-HAM) with cytarabine 1 g/m2 (age < 60 years) or 0.5 g/m2 (age ≥ 60 years) x 8 instead of maintenance. Results: A total of 576 patients (69.2%) achieved a complete remission (CR) those were 294 of 429 (68.5%) patients randomized to receive maintenance and 282 of 403 (70.0%) patients randomized to receive intensive consolidation S-HAM (p=n.s.). 190 patients received maintenance therapy as intended and 135 patients received an intensive consolidation therapy as intended. This prolonged follow-up analysis verified the superior relapse-free survival in all patients in the maintenance arm (10-year RFS 30.0 ± 5.6 versus 19.9 ± 6.1 %, p = 0.015). Stratified by age, the 10-year RFS was superior in younger patients < 60 years (36.9 ± 7.1 versus 25.2 ± 8.0 %, p = 0.038) and borderline significant in elderly patients (17.2 ± 4.5 versus 6.8 ± 6.2 %, p = 0.075). A subgroup analysis of known risk groups (lactate dehydrogenase (LDH) level < 700U/l versus ≥ 700U/l at diagnosis, cytogenetic risk profile, bone marrow blasts on day 16 after the start of the induction therapy) revealed a superior RFS in the subgroup of patients with LDH level > 700 U/l at diagnosis (33.5 ± 12.3 versus 18.2 ± 9.5 %, p = 0.043). This superior RFS also translated into a superior 10-year relapse-free interval (RFI) of all responding patients in the maintenance arm (35.7 ± 6.3 versus 27.6 ± 5.9 %, p = 0.015) with borderline significance in younger patients (42.9 ± 7.4 versus 35.0 ± 7.4 %, p = 0.053) and a significant difference in elderly patients (20.6 ± 10.0 versus 8.4 ± 7.5 %, p = 0.043). In this updated analysis, there was a trend, but no significant difference in the OS (maintenance arm: 10-year OS 24.3 ± 4.8, intensive consolidation arm: 19.7 ± 4.7 %, p = 0.148), and we verified a trend for a better OS in responding patients for the maintenance arm (10-year OS in responding patients 33.6 ± 7.5 versus 28.5 ± 6.2 %, p = 0.093). The event-free survival (EFS) also showed a trend towards better EFS in the maintenance arm (10-year EFS 20.7 ± 4.2 versus 14.8 ± 4.1 %, p = 0.082) which was significant in elderly patients (10-year EFS 10.5 ± 5.5 versus 3.9 ± 3.7 %, p = 0.044). Discussion: This updated analysis with a long-term follow-up of median 7.9 years from diagnosis and 7.1 years from CR verified the superior RFS and the trend for enhanced OS in responding patients. These results suggest the superiority of a prolonged monthly myelosuppressive maintenance therapy as compared to intensive consolidation S-HAM after TAD-HAM induction and TAD consolidation.

In order to assess long-term outcome of patients with localized (stage I or II) diffuse large-cell lymphoma treated with initial combination chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without involved-field radiotherapy following chemotherapy, we combined data from two prospective trials in Tucson (64 patients) and Vancouver (78 patients). Follow-up on 142 patients was updated and a variety of potential pretreatment prognostic factors were analyzed for impact on outcome. One hundred forty patients (99%) achieved a complete remission and there were no differences in outcome between institutions. Twenty-three patients have relapsed and 22 have died from lymphoma at a median follow-up of 4.4 years, resulting in an overall relapse-free survival of 82% at 5 years. There was no treatment-related mortality and were no instances of late cardiac toxicity or leukemia. Of the following potential pretreatment prognostic factors (age, stage, "B" symptoms, extranodal disease, gastrointestinal tract involvement, bulky disease, or disease above or below the diaphragm), only stage affected relapse-free survival (RFS) (P = .16) and survival (.003). Among 34% of patients over age 65, outcome was similar to younger patients. RFS for 108 patients treated with CHOP plus radiotherapy was not significantly superior to the use of CHOP alone in 34 patients (P = .2).

Abstract Severe aplastic anemia (SAA) is a life-threatening bone marrow failure disorder that can be treated with bone marrow transplantation, immunosuppressive therapy, and high-dose cyclophosphamide. Here, we report long-term follow-up on 67 SAA patients (44 treatment-naive and 23 refractory) treated with high-dose cyclophosphamide. At 10 years, the overall actuarial survival was 88%, the response rate was 71% with the majority being complete, and the actuarial event-free survival was 58% in 44 treatment-naive SAA patients. Patients with refractory SAA fared less well after high-dose cyclophosphamide therapy; at 10 years, overall actuarial survival, response, and actuarial event-free survival rates were 62%, 48%, and 27%, respectively. High-dose cyclophosphamide is highly effective therapy for severe aplastic anemia. Large randomized controlled trials will be necessary to establish how results of high-dose cyclophosphamide compare with either bone marrow transplantation or standard immunosuppressive regimens, such as antithymocyte globulin and cyclosporine.

Abstract Abstract 2299 Poster Board II-276 Introduction: Patients with low- and intermediate-risk AML have several options for consolidation therapy, including chemotherapy alone and ACST or AlloSCT. Since randomized studies comparing these approaches show no option to be clearly superior to the others, several centers focus on sequencing of therapies in terms of patient tolerance and toxicity. Since 1986 our preferred consolidation regimen at UCSF for these patients consists of high-dose chemotherapy with ASCT. Consequently, at the time of relapse, we are often presented with the need for a second transplant (usually AlloSCT), in the setting of prior ASCT. As there is a paucity of data describing the toxicity and efficacy of AlloSCT in this setting, we designed this study to evaluate these parameters. Patients and Methods: This is a retrospective-cohort, single-institution study of patients with AML treated at UCSF between 1986 and 2008 and who received a second transplant at the time of relapse. Patients were identified through our prospective database, and data were collected from electronic medical records and primary clinical charts when available. Dates of death were corroborated with the social security database. Statistical analysis was performed using STATA (v9). Censoring date for all analyses was July 31st, 2009. This study was approved by the UCSF institutional review board. Results: Thirty-one patients with AML were identified who underwent an AlloSCT in the setting of relapse following a prior ASCT, with a median follow up of 54 months. The median time from the first to the second transplant was 17 months (range: 6 – 48). The median age at the time of the AlloSCT was 43 years (range: 20 – 64). Response status at the time of transplant was: 17 patients (55%) in complete remission (CR), 12 patients (39%) with less than CR, and 2 patients (6%) with response status unknown. The transplant was myeloablative in 14 patients (45%), non-myeloablative in 13 patients (42%), and cord-blood-based in 4 patients (13%). The donor was unrelated in 17 patients (55%). There were 7 (18%) treatment-related deaths in the first 6 months and 10 (32%) treatment-related deaths overall (pulmonary toxicity: 4, graft-versus-host-disease: 3, and infection: 3). Twelve patients (39%) died due to progressive disease. The median overall survival was 7 months, with 48% and 31% of patients being alive at 12 and 24 months respectively. Remission status prior to transplant was the most significant predictor of survival; the median survival among complete responders vs. all others was 19 months vs. 3.5 months respectively (p=0.006). Following transplantation, the median relapse-free survival among responders was 38 months, with 31% of patients being relapse-free at last follow-up. The time between transplants, as well as age, sex, and intensity of conditioning regimen had no effect on overall and relapse-free survival in our cohort. However, peripheral stem cell transplant was associated with improved overall survival (compared to bone marrow, p=0.02), though this likely reflects different eras of supportive therapy. Conclusions: Our results suggest that AlloSCT is an effective approach for patients with AML with relapsed or refractory disease after a prior ASCT. In this cohort spanning 22 years, treatment-related mortality from AlloSCT was 32%, and 31% of responders remain free of relapse with long-term follow-up.

Abstract Background: Previously, in 201 adult patients with allogeneic hematopoietic cell transplantation from matched unrelated donors, we demonstrated that the addition of ATG-F to standard cyclosporine, methotrexate GvHD prophylaxis (control) significantly reduces acute and chronic GvHD without negatively affecting relapse and survival [1,2,3]. Methods: Now, we present final results after an extended follow-up (median 8.6, Q1 8.0, Q3 9.3 years) with regard to chronic GvHD, non-relapse mortality (NRM), relapse, relapse mortality, disease-free survival (DFS) and overall survival (OS). Additionally, we analyse the effect of ATG-F vs control on the composite endpoint severe GvHD (acute GvHD III-IV, extensive chronic GvHD) and relapse-free survival, and on time under immunosuppressive therapy. Since mortality within the first year after transplantation is usually high, we also analyse conditional survival, i.e. the OS probability after having survived 1 and 2 years after transplantation. Results: The incidence of extensive chronic GvHD after 8 years was 13.5% in the ATG-F group vs 51.8% in the control group (p<0.0001). The 8-year rates with respect to outcome were: NRM 20.5% vs 34.0% (p=0.15), relapse 35.2% vs 29.9% (p=0.54), relapse mortality 30.8% vs 28.8% (p=0.90), DFS 44.3% vs 36.1% (p=0.60), and OS 48.7% vs 36.8% (p=0.31), ATG-F vs control, respectively. ATG-F substantially increased the combined severe GvHD/relapse-free survival rate. The rates were 48.5% vs 20.4% after 1 year and 33.6% vs 13.0% after 8 years (p=0.0003), ATG-F vs control, respectively (see figure). The probability of being alive and free of immunosuppressive therapy was 46.8% in the ATG-F group and 11.2% in the control group at 8 years (p=0.0002). The survival probabilities increased when patients had survived the first year. The conditional 8 years-survival probability increased in the ATG-F group from 48.7% (unconditional) to 70.6% and 80.9% (conditional on having survived 1 and 2 years after transplantation), and in the control group from 36.8% (unconditional) to 58.5% and 71.7% (conditional on having survived 1 and 2 years after transplantation). Conclusion: The long-term follow-up of 8.6 years shows that ATG-F GvHD prophylaxis provides a sustained protective effect without increasing relapse and compromising survival. ATG-F in addition to standard cyclosporine, methotrexate as GvHD prophylaxis results in significantly improved severe GvHD/relapse-free survival. Furthermore, the stable results from our prospective trial after an extended long-term follow-up demonstrate that the choice to use ATG-F in unrelated donor transplantation after myeloablative conditioning substantially increases the probability of surviving free of immunosuppressive therapy, and thus reduces the risk associated with long-term immunosuppression.

Abstract Background Preoperative chemoradiotherapy with capecitabine is considered as a standard of care for locally advanced rectal cancer. The “Tratamiento de Tumores Digestivos” group (TTD) previously reported in a randomized Ph II study that the addition of Bevacizumab to capecitabine-RT conferred no differences in the pre-defined efficacy endpoint (pathological complete response). We present the follow-up results of progression-free survival, distant relapse-free survival, and overall survival data at 3 and 5 years. Methods Patients (pts) were randomized to receive 5 weeks of radiotherapy (45 Gy/25 fractions) with concurrent Capecitabine 825 mg/m2 twice daily, 5 days per week with (arm A) or without (arm b) bevacizumab (5 mg/kg once every 2 weeks). Results In our study, the addition of bevacizumab to capecitabine and radiotherapy in the neoadjuvant setting shows no differences in pathological complete response (15.9% vs 10.9%), distant relapse-free survival (81.0 vs 80.4 and 76.2% vs 78.2% at 3 and 5 years respectively), disease-free survival (75% vs 71.7 and 68.1% vs 69.57% at 3 and 5 years respectively) nor overall survival at 5-years of follow-up (81.8% vs 86.9%). Conclusions the addition of bevacizumab to capecitabine plus radiotherapy does not confer statistically significant advantages neither in distant relapse-free survival nor in disease-free survival nor in Overall Survival in the short or long term. Trial registration EudraCT number: 2009–010192-24. Clinicaltrials.gov number: NCT01043484.
