Objective: To provide a randomized comparison between Jadena® and Norplant® in terms of efficacy and acceptability among Indonesian women. Method: This study was a phase IV, open label, randomized, multicenter study throughout Indonesia. Subjects were Indonesian adult women who were randomized to receive Jadena® or Norplant® as their contraceptive method. The subjects were recruited from 6 large cities in Indonesia, such as Medan, Palembang, Jakarta, Semarang, Surabaya, and Makassar. Result: Of 600 subjects, 301 women getting to Jadena® and 299 women to Norplant® were enrolled between August 1998 and February 1999. The mean age was 29.8 (SD 5.3) years old, ranging from 18 to 40 years old. We did not find the pregnancy during the study. Non-pregnancy probability at the end of one year was similar between Jadena® (0.920 (SD 0.016)) and Norplant® users (0.916 (SD 0.084)). The continuation rates of Jadena® at one and three-year were 95.3% and 66.8%; whereas, the continuation rates of Norplant® was 94.3% at year-1 and 70.2% at year-3. Conclusion: The new two rod levonorgestrel subdermal system (Jadena®) showed similar efficacy with the old six capsule levonorgestrel subdermal system (Norplant®) in term of birth control. Both implant systems also have similar tolerability profile. Jadena® is easier to insert and remove than Norplant®. Keywords: birth control, efficacy, implant

Myopia Control

AimsTo evaluate the 1-year efficacy of two new myopia control spectacle lenses with lenslets of different asphericity.MethodsOne hundred seventy schoolchildren aged 8–13 years with myopia of −0.75 D to −4.75 D were randomised to receive spectacle lenses with highly aspherical lenslets (HAL), spectacle lenses with slightly aspherical lenslets (SAL), or single-vision spectacle lenses (SVL). Cycloplegic autorefraction (spherical equivalent refraction (SER)), axial length (AL) and best-corrected visual acuity (BCVA) were measured at baseline and 6-month intervals. Adaptation and compliance questionnaires were administered during all visits.ResultsAfter 1 year, the mean changes in the SER (±SE) and AL (±SE) in the SVL group were −0.81±0.06 D and 0.36±0.02 mm. Compared with SVL, the myopia control efficacy measured using SER was 67% (difference of 0.53 D) for HAL and 41% (difference of 0.33 D) for SAL, and the efficacy measured using AL was 64% (difference of 0.23 mm) for HAL and 31% (difference of 0.11 mm) for SAL (all p<0.01). HAL resulted in significantly greater myopia control than SAL for SER (difference of 0.21 D, p<0.001) and AL (difference of 0.12 mm, p<0.001). The mean BCVA (−0.01±0.1 logMAR, p=0.22) and mean daily wearing time (13.2±2.6 hours, p=0.26) were similar among the three groups. All groups adapted to their lenses with no reported adverse events, complaints or discomfort.ConclusionsSpectacle lenses with aspherical lenslets effectively slow myopia progression and axial elongation compared with SVL. Myopia control efficacy increased with lenslet asphericity.Trial registration numberChiCTR1800017683.

19564 Background: Emerging data suggest that initiating EPO therapy earlier (at a higher hemoglobin [Hb] trigger) in the setting of active CT may provide better maintenance of Hb within a target range with no adverse safety consequence. Reported here are the final results of the first study to explore the efficacy and safety of early vs standard intervention with EPO initiated Q3W at 120,000 U. Methods: This 16-wk open-label randomized study enrolled pts with non-myeloid malignancy, baseline (BL) Hb =11.0 and =12.0 g/dL, and CT planned for =9 wks. Pts were randomized (1:1) to receive EPO 120,000 U subcutaneously Q3W immediately (early intervention group, EIG) or when their Hb fell to <11.0 g/dL (standard intervention group, SIG). If, at any dosing visit after the first EPO dose, Hb decreased to <10.0 g/dL, pts were switched to EPO 40,000 U weekly (QW). Dose was withheld for Hb >13.0 g/dL at any dosing visit; dose was reduced for Hb >12.0 g/dL or Hb increase >1.5 g/dL in a 3-wk period (current prescribing information recommends target Hb not to exceed 12 g/dL). Hb response was defined as Percent Values in Range (PVR; the mean proportion of weekly Hb levels that were =11.0 and =13.0 g/dL) and by mean Hb change from BL. Hb data following switch to 40,000 U QW were censored. Results: A total of 136 pts were randomized (68 per group). Demographics were similar; BL Hb was 11.5 g/dL in both groups. PVR was 60% in the EIG and SIG. Mean Hb change from BL to final value on Q3W dosing was -0.1 g/dL in both groups. Among the 51 pts whose Hb fell below 11 g/dL in the SIG, their Hb decreased to a mean of 10.4 g/dL before initiation of EPO. Their subsequent mean Hb increase was 0.7 g/dL at the final visit on Q3W therapy. PRBC transfusion rates after the first 4 wks of EPO treatment were 8.8% (6/68) and 7.8% (4/51) for the EIG and SIG, respectively. In the EIG vs SIG, EPO was withheld in 38% vs 22% of pts and reduced in 43% vs 26% of pts. Two deaths and 6 clinically relevant TVEs while on EPO treatment were reported in each group. Conclusions: This is the first study to show EPO may be initiated at 120,000 U every 3 wks. Hb outcomes in the EIG and SIG were similar. These data provide further evidence that half-life of erythropoietins may not correlate with their effectiveness when used at extended dosing intervals. Future research is warranted.

BackgroundTo evaluate the safety and tolerability of ranibizumab 0.5 mg in patients with uni/bilateral neovascular age-related macular degeneration (nAMD) and best-corrected visual acuity (BCVA)<2/10 and/or second eye affected, regardless of BCVA.MethodsIn this 12-month, prospective, multicentre, open-label, single arm, pragmatic interventional study, patients (N=941) aged ≥ 50 years were to receive ranibizumab as per approved label, monthly until maximum stable visual acuity (VA) was achieved (initially, three or more injections may be required). Thereafter, patients were to be monitored monthly for VA and treatment was to be resumed if VA was reduced due to disease activity.ResultsOf the 936 patients treated with ranibizumab at least once during the study, 823/113 were unilaterally/bilaterally (not simultaneously) treated . The mean (SD) number of ranibizumab injections during the study was 5.4 (2.9)/10.6 (5.0) injections in uni/bilaterally treated patients. Three systemic drug-related adverse events (AEs) (all serious, all in unilaterally treated patients) and 18 systemic AE of special interest (AESIs) (11 serious, 16/2 in unilaterally/bilaterally treated patients) occurred during the study. The annual incidence rate (AIR) (events/1000 person-years) for systemic drug-related AEs, considering a 15-day/30-day risk period, 11.0/8.5 for unilaterally treated patients. Considering the same risk period, the AIR (events/1000 person-years) for systemic AESIs for unilaterally treated patients was 22.1/19.9. Considering a 30-day risk period, the AIR (events/1000 treated eye-years) of ocular drug-related AEs was 23 and AESIs was 11.5.ConclusionsThe low incidence of AEs and AESIs demonstrated the good safety and tolerability of ranibizumab in unilaterally/bilaterally treated patients with nAMD in this real-world setting.

Abstract BACKGROUND: Effective treatment of the elderly patient with acute myelogenous leukemia (AML) remains a challenging task. Elderly patients with AML usually respond poorly to standard induction chemotherapy. Response rates in elderly patients are in the range of 30–50% compared to 80–90% in younger patients. Moreover, prolonged hospitalization with treatment related mortality as high as 30% is typical in this older population. In a prior retrospective analysis done at our institution, azacitidine showed an overall response rate of 60% with limited toxicity when administered to patients older than 55 years of age with AML. We present an interim analysis of the first 8 patients enrolled in our prospective, phase II open label study using single agent azacitidine for elderly patients with AML. METHODS: This is a prospective, phase II open label study using azacitidine in patients ≥ 60 years with AML. Inclusion criteria: Newly diagnosed AML (de novo or secondary, WHO criteria) and ECOG ≤ 2. Promyelocytic (M3) phenotype was excluded. Patients with circulating blast count ≥ 30,000/mcl were treated with hydroxyurea until &lt; 30,000/mcl. Azacitidine was given at a dose of 100 mg/m2 subcutaneously for 5 consecutive days every 28 days until disease progression or significant toxicity. G-CSF was given to patients with neutropenia (ANC &lt; 1000/mcl) during all cycles excluding cycle one. RESULTS: Eight patients have been enrolled to date. The mean age of patients is 74 (range: 64–82 years). The mean baseline ECOG performance score was 1 with a mean during treatment of 1. Mean baseline bone marrow blast count was 53% (range: 21–92%). Overall response rate using the NCI response criteria was 75% (6/8): complete response (CR; n=2; 25%) and partial response (PR; n=4; 50%). The mean number of days on treatment was 117 (range: 4–247 days). The mean number of days hospitalized during therapy was 18 (range: 7–51 days) with the majority of therapy being given in the outpatient setting. The mean overall survival time from diagnosis for all patients was 180 days (range: 23–403). The mean overall survival time for responders was 200 days (range: 36–403). Three patients continue on therapy at 146 (PR), 153 (CR) and 247 (PR) days. Of the other responders, one went on to receive an allogeneic PBSCT, one died at 36 days from complications of a strangulated hernia, and one removed himself from study at 82 days (unconfirmed CR) to receive treatment closer to home. All patients were red blood cell (RBC) transfusion dependent at the start of the therapy. To date, two of the six responders (33%) became independent of RBC transfusion. Four patients were transfusion dependent for platelets at the start of therapy with two being non-responders and two achieving a PR. Non-hematological toxicity was limited to mild injection site skin reaction and fatigue in 63% (5/8) each. No treatment related deaths were observed. The dose and schedule of therapy remained constant in all patients except one who required a 25% dose reduction after cycle 3 due to drug induced marrow suppression. CONCLUSION: This interim analysis suggests that the administration of subcutaneous azacitidine in an accelerated dosing schedule to elderly patients with acute myelogenous leukemia is a feasible and well-tolerated alternative to standard induction chemotherapy.

PurposeTo compare the efficacy of aflibercept using a personalised versus fixed regimen in treatment-naïve participants with polypoidal choroidal vasculopathy (PCV).DesignA 52-week, randomised, open-label, non-inferiority, single-centre study that included participants with symptomatic PCV. Participants were randomised (3:1 ratio) to receive either personalised (n=40) or fixed 8-weekly treatment regimen (n=13). The personalised regimen allowed for either early treat and extend (T&E) after week 12 or late T&E with 3 additional 4-weekly aflibercept injections until week 24 in participants with residual polypoidal lesions (PL) on indocyanine green angiography (ICGA) at week 12.Main outcomes and measuresNon-inferiority of personalised to fixed regimen for mean change in best-corrected visual acuity (BCVA) from baseline to week 52 (non-inferiority margin: −5 letters). The key secondary outcomes include reduction in central subfield thickness (CSFT) on optical coherence tomography and the anatomical closure of PL on ICGA.ResultsOf the 53 participants, the mean (SD) age was 69.2 (8.1) years, 19 (35.8 %) were male. Personalised group was non-inferior to fixed for the primary end point (+8.1 vs +7.9 letters at week 52, respectively; difference 0.16, 95% CI −2.8 to 2.4, p=0.79). There was greater reduction in mean CSFT (SD) in the personalised versus fixed group (−248.8 (169.9) vs −164.8 (148.9) µm, p=0.03). Closure of PL occurred in 21 (55.2%) and 5 (41.6%) of study eyes in personalised and fixed groups, respectively at week 52 (p=0.41).ConclusionsPersonalised regimen achieved non-inferior BCVA gain and numerically higher PL closure compared with fixed regimen.Trial registration numberNCT03117634.

Purpose In patients with myeloma, thalidomide significantly improves outcomes but increases the risk of thromboembolic events. In this randomized, open-label, multicenter trial, we compared aspirin (ASA) or fixed low-dose warfarin (WAR) versus low molecular weight heparin (LMWH) for preventing thromboembolism in patients with myeloma treated with thalidomide-based regimens. Patients and Methods A total of 667 patients with previously untreated myeloma who received thalidomide-containing regimens and had no clinical indication or contraindication for a specific antiplatelet or anticoagulant therapy were randomly assigned to receive ASA (100 mg/d), WAR (1.25 mg/d), or LMWH (enoxaparin 40 mg/d). A composite primary end point included serious thromboembolic events, acute cardiovascular events, or sudden deaths during the first 6 months of treatment. Results Of 659 analyzed patients, 43 (6.5%) had serious thromboembolic events, acute cardiovascular events, or sudden death during the first 6 months (6.4% in the ASA group, 8.2% in the WAR group, and 5.0% in the LMWH group). Compared with LMWH, the absolute differences were +1.3% (95% CI, −3.0% to 5.7%; P = .544) in the ASA group and +3.2% (95% CI, −1.5% to 7.8%; P = .183) in the WAR group. The risk of thromboembolism was 1.38 times higher in patients treated with thalidomide without bortezomib. Three major (0.5%) and 10 minor (1.5%) bleeding episodes were recorded. Conclusion In patients with myeloma treated with thalidomide-based regimens, ASA and WAR showed similar efficacy in reducing serious thromboembolic events, acute cardiovascular events, and sudden deaths compared with LMWH, except in elderly patients where WAR showed less efficacy than LMWH.

OBJECTIVE: To assess whether colesevelam hydrochloride is absorbed in healthy volunteers. METHODS: A single-center, open-label, radiolabeled study was performed with 16 healthy volunteers. Subjects were administered non-radiolabeled colesevelam hydrochloride 1.9 g twice daily for 4 weeks, followed by a single dose of [14C]-colesevelam 2.4 g (480 μCi). These subjects continued to receive non-radioactive colesevelam 1.9 g twice daily for 4 days after administration of the radiolabeled dose. Blood, urine, and feces were collected immediately prior to administration of [14C]-colesevelam and at specified intervals after administration. The whole-blood equivalent concentration of colesevelam was calculated using data collected throughout the 96 hours following radiolabeled drug administration. The proportion of [14C]-colesevelam excreted through urine or feces was calculated based on the amount of radioactivity recovered up to 216 hours after the radiolabeled dose. RESULTS: The mean cumulative total recovery of [14C]-colesevelam in urine and feces was 0.05% and 74%, respectively. Excluding 2 subjects for whom cumulative recovery was <25%, the mean cumulative fecal recovery was 82%. The mean maximum whole-blood equivalent concentration of colesevelam was 0.165 ± 0.10 μg equiv/g 72 hours after administration of [14C]-colesevelam, which was estimated to be 0.04% of the administered dose. All blood samples contained <4 × the number of background counts (dpm). CONCLUSIONS: The cumulative recovery data in urine and feces are consistent with the conclusion that colesevelam is not absorbed and is excreted entirely through the gastrointestinal system.

Abstract Background Lyme neuroborreliosis (LNB) is often treated with intravenous ceftriaxone even if doxycycline is suggested to be noninferior to ceftriaxone. We evaluated the efficacy of oral doxycycline in comparison to ceftriaxone in the treatment of LNB. Methods Patients with neurological symptoms suggestive of LNB without other obvious reasons were recruited. The inclusion criteria were (1) production of Borrelia burgdorferi–specific antibodies in cerebrospinal fluid (CSF) or serum; (2) B. burgdorferi DNA in the CSF; or (3) an erythema migrans during the past 3 months. Participants were randomized in a 1:1 ratio to receive either oral doxycycline 100 mg twice daily for 4 weeks, or intravenous ceftriaxone 2 g daily for 3 weeks. The participants described their subjective condition with a visual analogue scale (VAS) from 0 to 10 (0 = normal; 10 = worst) before the treatment, and 4 and 12 months after the treatment. The primary outcome was the change in the VAS score at 12 months. Results Between 14 September 2012 and 28 December 2017, 210 adults with suspected LNB were assigned to receive doxycycline (n = 104) or ceftriaxone (n = 106). The per-protocol analysis comprised 82 patients with doxycycline and 84 patients with ceftriaxone. The mean change in the VAS score was −3.9 in the doxycycline group and −3.8 in the ceftriaxone group (mean difference, 0.17 [95% confidence interval, −.59 to .92], which is within the prespecified equivalence margins of −1 to 1 units). Participants in both groups improved equally. Conclusions Oral doxycycline is equally effective as intravenous ceftriaxone in the treatment of LNB. Clinical Trials Registration NCT01635530.

Background Brain atrophy, as assessed by magnetic resonance imaging (MRI), has been correlated with disability in patients with multiple sclerosis (MS). Recent evidence indicates that both white matter (WM) and gray matter (GM) are subject to atrophy in patients with MS. Although neurological deficiencies in MS are primarily due to loss of WM, the clinical significance of GM atrophy has not been fully explored in MS. Methods We have undertaken a three-year, open-label study, comparing 26 patients who elected to receive intramuscular interferon beta-1a (IFN β-1a) therapy, with 28 patients who elected not to receive therapy. Both groups had quantitative cranial MRI scans at study entry and after three years, and standardized clinical assessments every six months. Brain parenchymal fraction (BPF), GM fraction (GMF), and WM fraction (WMF) percent changes were calculated, and T2- and T1-lesion volumes (LVs) assessed. Results After three years, mean percent (%) change in BPF favored the IFN β-1a treatment group (IFN β-1a —1.3% versus the control group —2.5%, P=0.009), as did the mean percent change in GMF (+0.2 versus —1.4%, P=0.014), and the mean percent change in T1-LV (—9.3 versus +91.6%, P=0.011). At the end of the study, there was a significant within-patient decrease in BPF for both groups (P=0.02 for the IFN β-1a treatment group, and P<0.001 for the control group), a significant within-patient decrease in WMF for the IFN β-1a treatment group (P=0.01), and a significant decrease in GMF for the control group (P=0.013) when compared with baseline. Conclusion Over a three-year period, treatment with IFN β-1a significantly slowed the progression of whole-brain and GM atrophy, and of T1-hypointense LV accumulation, when compared with the control group.
