Real World Setting

Objective As first-line treatments for newly diagnosed adult immune thrombocytopenia (ITP), high-dose dexamethasone (HD-DXM) and conventional-dose prednisone achieve good initial responses, but their long-term efficacy is poor. To improve the long-term outcome of newly diagnosed ITP, we explored the efficacy and safety of HD-DXM with sequential prednisone maintenance therapy. Methods This retrospective study in a real-world setting assessed 72 consecutive newly diagnosed ITP patients administered first-line HD-DXM with sequential prednisone maintenance therapy from 1 June 2016 to 31 December 2019. Results Seventy patients obtained response (97.2%), and 55 achieved sustained response (SR) (76.4%). Fifty-three obtained complete remission (CR) (73.6%), and 39 achieved continuous CR at 6 months (54.2%). Among 36 anti-nuclear antibody-positive patients, 100% achieved response, and 28 achieved CR (77.8%). Among 24 antithyroid antibody-positive patients, 23 (95.8%) achieved response, and 20 achieved CR (83.3%). For patients with initial response, the 12-month probability of SR was 78.6%. For patients with initial CR, the 12-month probability of continuous CR was 64.2%. At 12 months, 21.4% of patients with initial response and 11.3% of patients with initial CR showed loss of treatment response. Conclusions HD-DXM with sequential prednisone as the first-line treatment for newly diagnosed ITP patients may achieve good clinical efficacy.

Abstract Background: Primary immune thrombocytopenia (ITP) is an acquired autoimmune disorder that results from accelerating platelet clearance, destruction, and production. Front-line therapy for newly diagnosed ITP includes corticosteroids, intravenous immune globulin, or anti-D immunoglobulin. However, after these single-agent therapies, relapses will occur in half of patients. We previously reported the safety, feasibility, and efficacy of the combination of dexamethasone, low-dose rituximab, and the thrombopoietin receptor agonist (TPO-Ra) eltrombopag as front-line treatment in newly diagnosed ITP. Romiplostim, another TPO-Ra is approved by the FDA for patients with chronic ITP. However, the safety, tolerability, and efficacy of romiplostim combined with low-dose rituximab, and high-dose dexamethasone in newly diagnosed ITP remain unknown. Objective: Our primary objectives were safety, and tolerability. Secondary objectives were initial response and relapse incidence. Methods: An open-label, single-arm study was performed in Hospital Universitario "Dr. José Eleuterio González" in Monterrey, Mexico (Clinical trials.gov NCT04588194). Eligible patients were newly diagnosed ITP patients, treatment-naïve, ≥18 years, with a platelet count ≤30×10 9/L. Patients were excluded if they had an active infection, pregnancy, or malignant disease. The treatment regimen was romiplostim (2 mcg/kg weekly, four doses), low-dose rituximab (100 mg weekly, four doses) and high-dose dexamethasone (40 mg PO, days 1-4). Dexamethasone was allowed up to 3 cycles. Partial (PR) and complete responses (CR) were defined as an increase in platelet counts ≥30×10 9/L (at least a doubling of the baseline count) and ≥100×10 9/L, respectively. Results: We included ten consecutive patients. The median age was 34.5 years (range, 17-63). Seven patients were men (70%). The median platelet account at diagnosis was 6x10 9/L (range 0-23), and median follow-up was 180 days (range 30-270). The median number of romiplostim doses was 3.5 (range 1-4), and three (30%) patients required dose adjustment due to thrombocytosis. All but one patient achieved response (CR or PR) at a median of 7 days (range 7-28). Five patients (50%) achieved CR at 28 days of treatment, and four patients (40%) PR. No significant adverse effects have occurred during treatment; one patient presented grade 1 myalgia and the other a grade 2 soft tissue infection. Five patients (50%) relapsed during follow-up. Recently, four (40%) patients remain in CR and three (30%) in PR. Conclusion: The combination of romiplostim, low-dose rituximab, and high-dose dexamethasone was safe and effective. This "total therapy" approach was associated with minimum side effects and rapid initial response. Prospective validation in a larger sample is needed. Figure 1 Figure 1.

e18710 Background: With the advent of poly(ADP-ribose) polymerase inhibitors (PARPi), options for first-line (1L) maintenance therapy in ovarian cancer (OC) have evolved in the US. This study described the use of 1L maintenance and assessed predictors of 1L maintenance use among PARPi-eligible patients (pts) with OC in a real-world setting. Methods: This retrospective cohort study included pts with newly diagnosed stage III/IV epithelial OC who received 6–9 cycles of 1L platinum-based chemotherapy (PBC) and primary or interval debulking surgery following neoadjuvant chemotherapy between Jan 1, 2016, and Feb 29, 2020, from the nationwide Flatiron Health electronic health record–derived deidentified database. The end of the last cycle of 1L PBC was defined as the index date. Those pts who started second-line chemotherapy within 2 months of the index date were excluded. Logistic regression was used to analyze variables with regard to 1L maintenance use. Results: In total, 463 pts were included; 21% received maintenance therapy, 79% received active surveillance. Baseline characteristics are shown in the table. Overall maintenance therapy use increased over the study period, from 7.7% to 37.7%. Pts with BRCA wild type were significantly less likely to receive maintenance therapy (odds ratio [OR]: 0.30; 95% CI, 0.16–0.59) than pts with BRCA mutation. Pts treated in 2018 (OR: 2.73; 95% CI, 1.25–5.98) and 2019 (OR: 8.78; 95% CI, 4.15–18.55) were significantly more likely to receive maintenance therapy than pts treated in 2017. Age, race, practice type, ECOG score, and residual disease status were not significant predictors of 1L maintenance use. Conclusions: Nearly 40% of pts with advanced stage OC received upfront maintenance therapy with an increasing trend over time, particularly in those with biomarker guidance. Research is warranted toward addressing barriers to the appropriate use of maintenance therapy.[Table: see text]

Abstract Introduction Primary immune thrombocytopenia (ITP) is an acquired autoimmune disorder that involves antibody and cell mediated destruction of platelets as well as suppression of their production. Prednisone is the initial standard therapy in adults1. High-dose dexamethasone as front-line therapy given as pulses of 40 mg per day for 4 consecutive days, was effective in 85% of patients, nevertheless, 50% relapsed within six months2. The prices of ITP drugs for 1 month of treatment in an adult range from prednisone; $16, eltrombopag; $5,934, intravenous immune globulin (IVIG) (80 g); $9,648, to rituximab (2 g); $15,5963. Only prednisone/dexamethasone and eltrombopag are available in oral presentation, for this reason, ambulatory treatment is an alternative for these patients. The trombopoietin receptor agonists are effective for the treatment of patients with chronic ITP, although response is dependent on continued administration. Eltrombopag is a small molecule agonist of the c-mpl (TpoR) receptor, which is the physiological target of thrombopoietin. This drug effectively raises the platelet count in adult patients (aged 18 years and over) as second/third line therapy, that is for patients refractory to corticosteroids and IVIG who have had their spleen removed or when splenectomy is not an option4. Our group, as well as others, has previously sought to improve response rates in these patients, particularly with the use of rituximab5, 6. To our knowledge neither eltrombopag nor romiplostim have been used as front line therapy in ITP, therefore the purpose of this study was to assess the efficacy of eltrombopag and dexamethasone in this setting. Patients and Methods This was a prospective, phase 2 study, using the combination of eltrombopag (50 mg PO once a day for 4 weeks) and high-dose dexamethasone (40 mg PO days 1,2,3,4) in untreated adult patients with immune thrombocytopenia or in patients with less than 7 days of treatment with corticosteroids. Complete response (CR) was defined as an increase in platelet count >100×109/L. Partial response (PR) was defined as an increase in the platelet count greater to 30 ×109/L according to standard criteria. Duration of response was considered from the day of initial administration to the first time of relapse (platelet count <30×109/L). Results Twelve consecutive patients were enrolled from June 2012 to June 2013, 6 women and 6 men. The median age at diagnosis was 50 years (range, 20 - 80 years). The median platelet count at diagnosis was 7 x 109/L (range, 2 - 29 x 109/L). Patients were followed for a median of 2.5 months (range 1.1 - 13). After steroid treatment at day +5, ten patients had responded (83.3%), five had achieved CR (41.7%), and five PR. After completing treatment with eltrombopag at day +34, all patients responded (100%), nine patients achieved CR (75%) and three PR (25%). Two patients relapsed in a median time of 39.5 days (range, 30.1 - 49), both regaining CR after treatment with another high-dose dexamethasone course and low-dose rituximab (4 doses of 100 mg every week). At 3 months follow-up 66.7% remained in CR and 33.3% in PR (n=6). At 6 months follow-up two patients remained in CR and two in PR (n=4). Time to best response achieved was 34 days from diagnosis (range, 19 – 64.1). At the end of follow-up 9 patients (75%) remained in CR and 3 patients in PR (25%). Total treatment cost per patient was $1,640 approximately. Conclusion Currently the initial treatment of ITP patients is based on prednisone or high dose dexamethasone with or without IVIG. This approach is associated with high cost and high relapse rate. The results from our pilot study suggest that high dose dexamethasone and eltrombopag are very effective as first line treatment for acute ITP in adults. This treatment is ambulatory, affordable and well tolerated; however, we still don't know if this approach will have a favorable impact on the relapse rate of this disease.

Abstract Background In current guidelines, thiopurines are still recommended as first-line maintenance therapy for patients with Crohn’s disease (CD). Due to their lack of immunogenicity, oral administration route and low costs, thiopurines are an attractive first-line treatment option. However, in recent studies the position of thiopurine monotherapy in CD has been questioned as a result of relatively lower overall effectiveness rates compared to ulcerative colitis. Real-world long-term effectiveness data substantiating the use and position of thiopurines in CD management remain sparse. We assessed long-term effectiveness of thiopurine monotherapy in CD using the population-based IBD South-Limburg (IBDSL) cohort. Methods All CD patients in the IBDSL cohort starting thiopurine monotherapy as first-line maintenance therapy between 1991–2014 were included. Thiopurine monotherapy was defined effective if either: (1) no escalation to biological treatment, (2) no course of corticosteroids, (3) no resective surgery or, (4) no hospitalization for active disease was required whilst on thiopurine treatment. Patients with early treatment discontinuation (i.e. &lt;3 months) were identified, including reason of discontinuation. Long-term effectiveness was assessed adjusting for differences in follow-up between patients using Kaplan-Meier analysis. Potential risk factors for therapy failure were identified using Cox regression. Results In total, 643/1162 (55.3%) CD patients (median follow-up: 8.5 years IQR 5.0–13.2) received first-line thiopurine monotherapy after a median of 9.7 months (IQR 3.2–31.3) after diagnosis. Therapy was discontinued within three months in 164 patients (25.5%), mainly due to adverse events [Figure 1]. Thiopurine monotherapy was effective for the duration of treatment in 229/479 (35.6%) patients, corresponding to estimated effectiveness rates of 62.9%, 43.9% and 31.2% after 1, 5 and 10 years, respectively [Figure 1–2]. No significant difference in effectiveness was observed after stratifying for era of thiopurine initiation (pre-biological (1991–1998) vs. biological (&gt;1999) era, p=0.84). Factors associated with thiopurine failure were stricturing disease (aHR 1.41, 95%CI 1.01–1.96) and upper GI involvement (aHR 1.52, 95%CI 1.02–2.28) at diagnosis. During follow-up, 40/229 patients with a durable response discontinued treatment due to quiescent disease. Of these, 35 patients (87.5%) remained without treatment 24 months after discontinuation. Conclusion Real-world data from this population-based study demonstrate that thiopurine monotherapy remains an effective and durable first-line treatment option for CD, even in the biological era. These results should be considered in the ongoing discussion regarding the position of thiopurine therapy.
