Abstract Although epoetin alfa is commonly used weekly for the treatment of chemotherapy (CT)-induced anemia, most CT is given at three week intervals. Therefore, to provide increased patient convenience we examined a dosing regimen that would allow patients to receive epoetin alfa 80,000 U Q3W during maintenance therapy. This open-label, multi-center study had two phases: Initiation Phase (IP) of 60,000 U QW to achieve target hemoglobin (Hb) of 12 g/dL (maximum duration 12 weeks), followed by a Maintenance Phase (MP) of 80,000 U Q3W to maintain Hb between 11.0 and 12.5 g/dL. Only those patients achieving Hb ≥ 12 g/dL in the IP entered the MP; once target Hb was achieved, patients proceeded to MP at the beginning of their next full CT cycle. Patients were withdrawn from the MP if Hb decreased to < 11 g/dL. Doses were held for Hb > 13 g/dL and reduced for rate of rise > 1.3 g/dL/2 weeks. Maximum study duration (IP + MP) was 24 weeks. Patients ≥ 18 years of age with non-myeloid malignancy, baseline Hb ≤ 11 g/dL, and CT planned Q3W for ≥ 15 weeks were enrolled. Endpoints included proportion of patients achieving hematopoietic response in the IP (≥ 2 g/dL Hb increase from baseline or Hb ≥ 12 g/dL) and proportion maintaining mean Hb between 11.0 and 12.5 g/dL in the MP. Also analyzed was the proportion of patients maintaining mean Hb between 11.0 and 13.0 g/dL in the MP. A total of 115 patients were enrolled and received at least one dose of epoetin alfa; mean age was 62.2 ± 11.9 years, 66.1% were female, mean baseline Hb was 10.2 ± 0.8 g/dL, and 86.1% had solid tumors. During the IP, 84 of 115 (73.0%) patients achieved hematopoietic response (≥ 2 g/dL Hb increase from baseline or Hb ≥ 12 g/dL). Seventy-three patients (63.5%) who achieved Hb ≥ 12 g/dL entered the MP after a median of 6.0 weeks in IP and spent a mean of 9.8 weeks in MP. Fifty-four of 73 (74.0%) maintained an average Hb between 11.0 and 12.5 g/dL over the course of the MP; 64 (87.7%) maintained an average Hb between 11.0 and 13.0 g/dL over the course of the MP. Twenty-five (34.2%) patients were withdrawn from the MP because Hb decreased to < 11 g/dL. Of 115 patients dosed in IP, 30 (26.1%) had doses reduced and 31 (27.0%) had doses held; of 73 patients dosed in MP, 9 (7.8%) had doses reduced and 16 (13.9%) had doses held. Fifty-one (44.3%) patients experienced serious adverse events. Eleven (9.6%) patients experienced clinically relevant thrombotic vascular events. Two and 4 patients discontinued due to adverse events in the IP and MP, respectively. Eight (7.0%) patients died during the study or within 30 days after last study dose. Although 60,000 U QW was used during the IP to achieve a HR, 40,000 U QW is the recommended initiation dose of epoetin alfa. This study suggests that epoetin alfa 80,000 U administered every three weeks to patients on a Q3W CT regimen is an effective option for maintenance therapy of CT-induced anemia.

Abstract Epoetin alfa administered weekly is a proven treatment for chemotherapy (CT)-induced anemia. To increase patient convenience we examined a dosing regimen that would allow patients to receive epoetin alfa 60,000 U Q2W during maintenance therapy. This open-label, multi-center study had two phases: Initiation Phase (IP) of 60,000 U once weekly (QW) to achieve a target hemoglobin (Hb) of 12 g/dL (maximum duration 12 weeks), followed by a Maintenance Phase (MP) of 60,000 U Q2W to maintain Hb between 11.0 and 12.5 g/dL. Only those patients achieving Hb ≥ 12 g/dL in the IP entered the MP. Patients were withdrawn from the MP if Hb decreased to < 11 g/dL. Doses were held for Hb > 13 g/dL and reduced for rate of rise of > 1.3 g/dL/2weeks. Maximum study duration (IP + MP) was 24 weeks. Patients ≥ 18 years of age with non-myeloid malignancy, baseline Hb ≤ 11 g/dL, and CT planned QW or every 4 weeks for at least 16 weeks were enrolled. Endpoints included proportion of patients achieving hematopoietic response in the IP (≥ 2 g/dL Hb increase from baseline or Hb ≥ 12 g/dL) and proportion maintaining mean Hb between 11.0 and 12.5 g/dL in the MP. A total of 129 patients were enrolled and received at least one dose of epoetin alfa; mean age was 62.6 ± 13.0 years, 65.9% were female, mean baseline Hb was 10.0 ± 0.9 g/dL, and 92.2% had solid tumors. During the IP, 84 of 129 (65.1%) patients achieved hematopoietic response (≥ 2 g/dL Hb increase from baseline or Hb ≥ 12 g/dL). The eighty-four patients who achieved Hb ≥ 12 g/dL entered the MP after a median of 4.0 weeks in IP; treatment duration in MP was 13.2 weeks on average. Fifty-one of 84 (60.7%) maintained an average Hb between 11.0 and 12.5 g/dL over the course of the MP. Sixteen (19.0%) patients were withdrawn from the MP because Hb decreased to < 11 g/dL. Of 129 patients dosed in IP, 14 (10.9%) had doses reduced and 8 (6.2%) had doses held; of 84 patients dosed in MP, 47 (36.4%) had doses reduced and 53 (41.1%) had doses held. Sixty-five (50.4%) patients experienced serious adverse events. Fifteen (11.6%) patients experienced clinically relevant thrombotic vascular events. Three and 5 patients discontinued due to adverse events in the IP and MP, respectively. Fifteen (11.6%) patients died during the study or within 30 days after last study dose. Although 60,000 U QW was used during the IP to achieve a HR, 40,000 U QW is the recommended initiation dose of epoetin alfa. This study of patients receiving CT every 1 or 4 weeks, demonstrated that the majority of those who achieved a HR are able to maintain an acceptable Hb level with epoetin alfa 60,000 U every two weeks.

Abstract The efficacy of epoetin alfa (EPO) 40,000 U SC once weekly (QW) has been established in clinical studies in anemic patients (pts) with cancer receiving chemotherapy (CT). Higher starting doses of EPO may increase initial hemoglobin (Hb) response and subsequent less frequent maintenance dosing may improve dosing flexibility for pts and health care providers. This ongoing, open-label, multicenter, 24-week (wk) study was designed to evaluate the efficacy and safety of EPO at a starting dose of 60,000 U SC QW to a target Hb of 12 g/dL in the Initiation Phase (IP; maximum of 12 wks), followed by 80,000 U SC every 3 wks (Q3W) in the Maintenance Phase (MP) to maintain Hb in the range 11.5–12.5 g/dL. Eligible pts were ≥18 years with nonmyeloid malignancy, had baseline (BL) Hb <11 g/dL, and were scheduled to receive CT Q3W for ≥15 wks. Pts who achieved Hb ≥12 g/dL during the IP subsequently entered the MP; however, pts did not receive the first Q3W maintenance dose until start of the next Q3W CT cycle. Pts were withdrawn if Hb decreased to <11 g/dL during the MP. The primary endpoint was proportion of pts in the IP who achieved an Hb ≥12 g/dL or an Hb increase ≥2 g/dL from BL. Secondary endpoints included Hb increase ≥1 g/dL but <2.0 g/dL from BL in IP, maintenance of mean Hb 11.5–12.5 g/dL in the MP, maintenance of mean Hb >11.0 g/dL but <11.5 g/dL in MP, Hb over time, and transfusions. All Hb and response rates were independent of RBC transfusion within the previous 28 days. Study enrollment was terminated at 115 pts. In this preliminary analysis, the first 69 pts (mean age, 62 years; 65% women; 87% ECOG 0-1) enrolled and who received ≥1 dose of study drug were evaluable for safety and efficacy. Mean BL Hb was 10.2 ± 0.8 g/dL. The proportion of pts in the IP who achieved an Hb ≥12 g/dL or an Hb increase ≥2 g/dL from BL was 74% (49/69). The proportion of pts in the IP with an Hb increase ≥1 g/dL but <2 g/dL from BL was 9% (6/69). Forty-one (59%) pts entered the MP after a median of 5.0 wks in the IP and spent an average of 7.1 wks in the MP. Of these pts, 33 (80%) maintained an average Hb of 11.5–12.5 g/dL and 3 (7%) maintained an average Hb >11.0 g/dL but <11.5 g/dL over the course of the MP. During the MP, mean Hb was 12.1 ± 0.6 g/dL at entry, 11.8 ± 1.0 g/dL (n=15) after 8 wks of Q3W dosing, and 11.6 ± 1.1 g/dL (n=38) at final value. Eleven (27%) pts were withdrawn during the MP because Hb decreased to <11 g/dL. EPO dose was reduced in 25% (17/69) of pts in the IP and in 39% (16/41) of pts in the MP due to Hb >13 g/dL or Hb increase >1.3-g/dL in 2 wks. Thirty-five percent (24/69) of pts had a dose of EPO held at any time during the study for Hb >13 g/dL or another reason. Five (7%) pts were transfused after study day 28. Twenty-six (38%) pts experienced serious adverse events (AEs). Eight (12%) pts experienced a clinically relevant thrombovascular event. Two (3%) pts discontinued due to AEs. Nine (13%) pts died during the study or within the 90-day follow-up period. These preliminary data suggest that initial dosing of EPO 60,000 U QW is associated with a hematopoietic response rate (Hb ≥12 g/dL or Hb increase ≥2 g/dL from BL) of ~75% in pts with cancer and anemia receiving CT, similar to the response rate reported historically for EPO 40,000 U SC QW with dose escalation to 60,000 U SC QW. In addition, among pts who achieved a target Hb ≥12 g/dL with QW dosing and then received Q3W maintenance dosing, EPO 80,000 U SC Q3W maintained mean Hb above 11 g/dL in >85% of pts.

AbstractBackgroundDeutetrabenazine is approved to treat tardive dyskinesia (TD) in adults and is titrated weekly by 6 mg/day, from 12 to 48 mg/day, based on dyskinesia control and tolerability. This analysis compared the safety of deutetrabenazine during titration versus maintenance.MethodsSafety was assessed during titration versus maintenance using integrated data from two 12-week placebo-controlled studies (ARM-TD and AIM-TD) and the open-label extension study. Rates were compared for overall and serious adverse events (AEs), AEs leading to discontinuation, treatment-related AEs, common AEs (≥4%), and specific AEs (parkinsonism, suicidal ideation, akathisia, restlessness).ResultsIn titration versus maintenance, AE rates with placebo (n=130) were: overall, 43.1% vs 25.4%; serious, 4.6% vs 2.3%; leading to discontinuation, 3.1% vs 0; treatment-related, 26.9% vs 10.0%. For placebo, common AEs during titration were somnolence, headache, nausea, fatigue, and dry mouth; none occurred during maintenance. In titration versus maintenance, AE rates in fixed-dose deutetrabenazine 12–36 mg (n=216) were: overall, 33.3–38.9% vs 22.2–29.2%; serious, 2.8–6.9% vs 0–1.4%; leading to discontinuation, 2.8–5.6% vs 0; treatment-related, 8.3–16.7% vs 8.3–13.9%. For fixed-dose deutetrabenazine, common AEs during titration were headache, diarrhea, nasopharyngitis, depression, hypertension, and dry mouth; headache was the only common AE during maintenance. In titration versus maintenance, AE rates with flexible-dose deutetrabenazine (n=168) were: overall, 49.4% vs 32.7%; serious, 3.6% vs 2.4%; leading to discontinuation, 2.4% vs 0.6%. For flexible-dose deutetrabenazine, the only common AE during titration was somnolence; none occurred during maintenance. Rates of parkinsonism, suicidal ideation, akathisia, and restlessness were low and comparable in titration and maintenance.ConclusionsDeutetrabenazine was well-tolerated, with AE rates similar to placebo during both phases; AE rates were higher during titration and decreased during maintenance.FundingTeva Pharmaceutical Industries Ltd., Petach Tikva, Israel

ObjectivesTo determine the long-term safety and efficacy of allopurinol dose escalation (DE) to achieve target serum urate (SU) in gout.MethodsPeople, including those with chronic kidney disease, who completed the first 12 months of a randomised controlled trial continued into a 12-month extension study. Participants randomised to continue current dose for the first 12 months began allopurinol DE at month 12 if SU was ≥6 mg/dL (control/DE). Immediate DE participants who achieved target SU maintained allopurinol dose (DE/DE). The primary endpoints were reduction in SU and adverse events (AEs) at month 24.ResultsThe mean (SE) change in SU from month 12 to 24 was −1.1 (0.2) mg/dL in control/DE and 0.1 (0.2) mg/dL in DE/DE group (p<0.001). There was a significant reduction in the percentage of individuals having a gout flare in the month prior to months 12 and 24 compared with baseline in both groups and in mean tophus size over 24 months, but no difference between randomised groups. There were similar numbers of AEs and serious adverse events between groups.ConclusionsThe majority of people with gout tolerate higher than creatinine clearance-based allopurinol dose and achieve and maintain target SU. Slow allopurinol DE may be appropriate in clinical practice even in those with kidney impairment.Trial registration numberACTRN12611000845932

Abstract Background This study aimed to test the feasibility and titration methods to achieve specific BP control targets in hypertensive patients of rural China. Methods A randomized, controlled, open-label trial was conducted in Rongcheng, China. We enrolled 105 hypertensive participants aged over 60 years, and who had no history of stroke and cardiovascular disease. The patients were randomly assigned to one of three systolic BP target groups: standard: 140 - < 150mmHg; moderately intensive: 130 - < 140mmHg; and intensive: <130mmHg. Patients were followed for 6 months. Discussion The optimal target for SBP lowering is still uncertain worldwide and such information is critically needed, especially in China. However, in China the rates of awareness, treatment and control are only 46.9%, 40.7% and 15.3%, respectively. It is challenging to achieve BP control in the real world and it is very important to develop population-specific BP control protocols that fully consider the population’s characteristics, such as age, sex, socio-economic status, compliance, education level and lifestyle. This randomized trial showed feasibility and safety of the titration protocol to achieve desirable SBP targets (<150, <140, and <130mmHg) in a sample of rural Chinese hypertensive patients. The three BP target groups had similar baseline characteristics. After 6 months of treatment, the mean SBP measured at an office visit was 137.2mmHg, 131.1mmHg, and 124.2mmHg in the three groups. Home BP and central aortic BP measurements were also obtained. At 6 months, home BP measurements (2 hours after drug administration) showed a mean SBP of 130.9 mmHg in the standard group, 124.9 mmHg in the moderately intense group, and 119.7 mmHg in the intensive group. No serious adverse events were recorded over the 6-month study period. Rates of adverse events including dry cough, palpitations, and arthralgia were low and showed no significant differences between the three groups. This trial gained real world experience and laid the foundation for a future large-scale BP target study.

Introduction: Hyperkalemia (potassium >5.0 mEq/L) affects heart failure patients with renal disease regardless of the use of renin–angiotensin–aldosterone system inhibitors (RAASi). The open-label TOURMALINE study showed that patiromer, a sodium-free, nonabsorbed potassium binder, lowers serum potassium of hyperkalemic patients similarly when given with or without food; unlike prior studies, patients were not required to be taking RAASi. We conducted post hoc analyses to provide the first report of patiromer in patients not taking RAASi. Methods: Hyperkalemic patients received patiromer, 8.4 g/d to start, adjusted to achieve and maintain serum potassium of 3.8 to 5.0 mEq/L. If taking RAASi, stable doses were required. The primary end point was the proportion of patients with serum potassium 3.8 to 5.0 mEq/L at week 3 or 4. This analysis presents data by patients taking or not taking RAASi. Results: Demographics and baseline characteristics were similar in patients taking (n = 67) and not taking RAASi (n = 45). Baseline mean (SD) serum potassium was 5.37 (0.37) mEq/L and 5.42 (0.43) mEq/L in patients taking and not taking RAASi, respectively. Mean (SD) daily patiromer doses were similar (10.7 [3.2] and 11.5 [4.0] g, respectively). The primary end point was achieved in 85% (95% confidence interval [CI]: 74-93) of patients taking RAASi and in 84% (95% CI: 71-94) of patients not taking RAASi. From baseline to week 4, the mean (SE) change in serum potassium was −0.67 (0.08) mEq/L in patients taking RAASi and −0.56 (0.10) mEq/L in patients not taking RAASi (both P < .0001 vs baseline, P = nonsignificant between groups). Adverse events were reported in 26 (39%) patients taking RAASi and 25 (54%) not taking RAASi; the most common adverse event was diarrhea (2% and 11%, respectively; no cases were severe). Five patients (2 taking RAASi) reported 6 serious adverse events; none considered related to patiromer. Conclusions: Patiromer was effective and generally well-tolerated for hyperkalemia treatment, whether or not patients were taking RAAS inhibitors.

Background: High platelet turnover (HPT) is implicated in incomplete platelet inhibition and high platelet reactivity (HPR) during immediate release aspirin therapy in type II diabetes patients (T2DM). Durlaza is a new, extended-release orally administered aspirin formulation developed to provide 24-hour antithrombotic effects with once-daily dosing. Methods: In this open-label, single-center study, T2DM patients (n=40) and a history of cardiovascular disease (CVD) or multiple CVD risk factors were treated with daily 162.5 mg Durlaza for 14±4 days and adverse events were collected. Antiplatelet effects were determined by conventional aggregation (LTA), Multiplate analyzer, thrombelastography with PlateletMapping, PlateletWorks ,VerifyNow Assay, and serum thromboxane B2 (TxB2) at 1, 12, 16, and 24 hrs after the last dose. HPT was defined as immature platelet fraction of ≥3.0% or MPV≥11.0 fl. Patients exhibiting HPT and/or HPR (based on previously published cutpoints in ≥2 assays) were treated with Durlaza at 325mg for 14± 4 days and platelet function testing was repeated. Results: Prevalence of HPT and HPR was 47% and 27%, respectively. There was no loss of antiplatelet effect at 12, 16 and 24 h versus 1 h by all assays (Table 1). All patients responded to 162.5mg Durlaza as measured by arachidonic acid-induced aggregation with LTA and platelet reactivity levels were low at all timepoints (Table). Serum TxB2 was lower at 12 h (p<0.03) as compared to 1 h after 162.5mg and was lower at all times with the 325 mg vs. the 162.5 mg Durlaza (p < 0.05). HPT did not affect the PD profile of Durlaza (Pts with HPT vs. no HPT, p=NS for all). Patients had no serious adverse events and low treatment related AE rate (<5%). Conclusion: In this first comprehensive assessment, a new, extended-release 162.5 Durlaza provided sustained antiplatelet effects over 24 h in T2DM patients with a favorable safety profile. Doubling the dose further lowered serum TxB2 in pts with HPT and/or HPR.

8567 Background: Clinical trial (CT) IMpower133 met both primary endpoints and is the first CT to show significant clinical improvement over standard chemotherapy (C) with a good safety profile in first line (1L) ES-SCLC. The addition of ATZ to CB + ET resulted in an OS landmark of 34% and 22% compared to 21% and 16.8% of patients alive at 18 and 24 months respectively versus C. IMfirst evaluates ATZ + CB or CP + ET in a broader patient population than the pivotal study. ECOG Performance status (PS) 2, asymptomatic untreated brain metastases, underlying stable autoimmune diseases and HIV+ pts are eligible. IMfirst also includes the possibility of 6 C induction cycles according to investigator´s choice and consolidation radiotherapy. Methods: To evaluate the safety and efficacy of ATZ added to CB or CP + ET as 1L treatment in an interventional real world setting of ES-SCLC. Exploratory endpoints include tumor biomarker analysis related to ATZ. Results: As of Oct 2020, 117 pts had been enrolled, 105 treated with ATZ + CB + ET and 12 with ATZ + CP + ET. The median age was 65 years (Y) (range 35-89); 84 males; 14 pts (12%) had CNS metastases and 66 pts were current smokers and 50 former smokers, one had never smoked. The PS was 0 in 28 pts (24%), 1 in 75 (64%) and 2 in 14 (12%). The median of cycles of ATZ received was 4 for all the pts (range 1-12) and 2 for the pts (40) in maintenance phase (range 1-8). Number of pts with adverse events (AEs) was 109, 36 with Serious Adverse Events (SAEs) and 63 with AEs. 8 pts had SAEs related to treatment, 4 had adverse events of special interest and 13 pts discontinued the treatment due to AEs: 6 to ATZ, 12 to CB or CP and 10 to ET, 1 patient discontinued ATZ due to a related AE. Table shows the treatment related AEs (TRAEs). No grade 5 TRAEs were reported. Conclusions: IMfirst induction phase analysis confirms the safety profile of ATZ plus C in a broader population of patients. Efficacy, biomarker and further safety analyses will be presented in the future with longer follow up.[Table: see text]

Abstract Background Combined inhibition of phosphatidylinositol 3-kinase (PI3K) and the mammalian target of rapamycin (mTOR) complexes may be an efficient treatment for acute leukemia. The primary objective of this phase I single center open label study was to determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of the dual pan-class I PI3K and mTOR inhibitor BEZ235 in patients with advanced leukemia. Methods Herein patients > 18 years of age who had relapsed or showed refractory leukemia were treated with BEZ235 (orally at 300–400 mg BID (cohort − 1/1)) to assess safety, tolerability, preliminary efficacy and pharmacokinetic (PK). Adverse events data and serious adverse events were analyzed and haematological and clinical biochemistry toxicities were assessed from laboratory test parameters. Response was assessed for the first time at the end of cycle 1 (day 29) and after every subsequent cycle. Pharmacokinetic and pharmacodynamic analyses of BEZ235 were also included (BEZ235 plasma levels, phosphorylation of AKT, S6 and 4EBP1). On statistics this trial is a multiple ascending dose study in which a following variant of the 3 + 3 rule (“Rolling Six”), a minimum of 6 and a maximum of 12 patients was recruited for the dose escalation and another 5 were planned for the expansion phase. Results Twenty-four patients with ALL (n = 11) or AML (n = 12) or CML-BP (n = 1) were enrolled. All patients had failed one (n = 5) or more lines of therapy (n = 5) and 14 patients were in refractory / refractory relapse. No formal MTD was defined, stomatitis and gastrointestinal toxicity at 400 mg BID dose was considered incompatible with prolonged treatment. The RP2D of BEZ235 was defined as 300 mg BID. Four of 24 patients showed clinical benefit. Twenty-two of 24 patients discontinued because of progression, (median time to progression 27 days (4d-112d). There was no association between PK parameters and efficacy or tolerability. Conclusions Combined inhibition of PI3K and mTOR inhibits a clinically meaningful driver pathway in a small subset of patients with ALL, with no benefit in patients with AML.

Background: In adults with primary focal segmental glomerulosclerosis (FSGS), daily prednisone may induce complete remissions (CR) and partial remissions (PR), but relapses are frequent and adverse events are common. Methods: We carried out 2 open-label, uncontrolled trials to explore the efficacy and tolerability of pulse oral dexamethasone as an alternative to daily prednisone. We enrolled adult patients with proteinuria > 3.5 g/day despite the use of renin-angiotensin-aldosterone blockade. In the first trial, we enrolled 14 subjects with FSGS and administered 4 dexamethasone doses (25 mg/m2) daily for 4 days, repeated every 28 days over 32 weeks. The second trial involved a more intensive regimen. Eight subjects received 4 dexamethasone doses of 50 mg/m2 every 4 weeks for 12 weeks, followed by 4 doses of 25 mg/m2 every 4 weeks for 36 weeks; subjects were randomized to 2 doses every 2 weeks or 4 doses every 4 weeks. Results: In the first trial, we enrolled 13 subjects with FSGS and 1 with minimal change disease and found a combined CR and PR rate of 36%. In the second trial, we enrolled 8 subjects. The combined CR and PR rate was 29%. Analysis combining both trials showed a combined CR and PR rate of 33%. Adverse events were observed in 32% of subjects, with mood symptoms being most common. There were no serious adverse events related to the study. Conclusion: We conclude that high dose oral dexamethasone is well tolerated by adults with idiopathic nephrotic syndrome and may have some efficacy.
