Abstract
BACKGROUND Type 1 diabetes is characterised by progressive loss of functional β-cell mass, necessitating insulin treatment. We aimed to investigate the hypothesis that combining anti-interleukin (IL)-21 antibody (for low-grade and transient immunomodulation) with liraglutide (to improve β-cell function) could enable β-cell survival with a reduced risk of complications compared with traditional immunomodulation. METHODS This randomised, parallel-group, placebo-controlled, double-dummy, double-blind, phase 2 trial was done at 94 sites (university hospitals and medical centres) in 17 countries. Eligible participants were adults aged 18-45 years with recently diagnosed type 1 diabetes and residual β-cell function. Individuals with unstable type 1 diabetes (defined by an episode of severe diabetic ketoacidosis within 2 weeks of enrolment) or active or latent chronic infections were excluded. Participants were randomly assigned (1:1:1:1), with stratification by baseline stimulated peak C-peptide concentration (mixed-meal tolerance test [MMTT]), to the combination of anti-IL-21 and liraglutide, anti-IL-21 alone, liraglutide alone, or placebo, all as an adjunct to insulin. Investigators, participants, and funder personnel were masked throughout the treatment period. The primary outcome was the change in MMTT-stimulated C-peptide concentration at week 54 (end of treatment) relative to baseline, measured via the area under the concentration-time curve (AUC) over a 4 h period for the full analysis set (intention-to-treat population consisting of all participants who were randomly assigned). After treatment cessation, participants were followed up for an additional 26-week off-treatment observation period. This trial is registered with ClinicalTrials.gov, NCT02443155. FINDINGS Between Nov 10, 2015, and Feb 27, 2019, 553 adults were assessed for eligibility, of whom 308 were randomly assigned to receive either anti-IL-21 plus liraglutide, anti-IL-21, liraglutide, or placebo (77 assigned to each group). Compared with placebo (ratio to baseline 0·61, 39% decrease), the decrease in MMTT-stimulated C-peptide concentration from baseline to week 54 was significantly smaller with combination treatment (0·90, 10% decrease; estimated treatment ratio 1·48, 95% CI 1·16-1·89; p=0·0017), but not with anti-IL-21 alone (1·23, 0·97-1·57; p=0·093) or liraglutide alone (1·12, 0·87-1·42; p=0·38). Despite greater insulin use in the placebo group, the decrease in HbA1c (a key secondary outcome) at week 54 was greater with all active treatments (-0·50 percentage points) than with placebo (-0·10 percentage points), although the differences versus placebo were not significant. The effects diminished upon treatment cessation. Changes in immune cell subsets across groups were transient and mild (<10% change over time). The most frequently reported adverse events included gastrointestinal disorders, in keeping with the known side-effect profile of liraglutide. The rate of hypoglycaemic events did not differ significantly between active treatment groups and placebo, with an exception of a lower rate in the liraglutide group than in the placebo group during the treatment period. No events of diabetic ketoacidosis were observed. One participant died while on liraglutide (considered unlikely to be related to trial treatment) in connection with three reported adverse events (hypoglycaemic coma, pneumonia, and brain oedema). INTERPRETATION The combination of anti-IL-21 and liraglutide could preserve β-cell function in recently diagnosed type 1 diabetes. The efficacy of this combination appears to be similar to that seen in trials of other disease-modifying interventions in type 1 diabetes, but with a seemingly better safety profile. Efficacy and safety should be further evaluated in a phase 3 trial programme. FUNDING Novo Nordisk.

Clinical cancer research : an official journal of the American Association for Cancer Research. 2021;(5):1267-1277
Abstract
PURPOSE This phase Ia/Ib PACT study evaluated the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of a new programmed cell death ligand 1 (PD-L1) inhibitor, LY3300054, as monotherapy or in combination with ramucirumab, abemaciclib, or merestinib (a type II MET kinase inhibitor) in patients with advanced, refractory solid tumors (NCT02791334). PATIENTS AND METHODS Patients were enrolled into cohorts of escalating LY3300054 dose (phase Ia) as monotherapy (N = 15) or combined with ramucirumab (N = 10), abemaciclib (N = 24), or merestinib (N = 12). The phase Ib dose expansion enrolled 8 patients with melanoma in the monotherapy arm and 12 patients with pancreatic cancer in the merestinib combination arm. Combination treatments were administered concurrently from day 1 of each cycle. A 14-day lead-in abemaciclib arm was also explored. Primary endpoints were dose-limiting toxicity (DLT) and safety. RESULTS Treatment-related adverse events included fatigue and nausea in the monotherapy arm (13% for each), hypothyroidism (30%) in the ramucirumab arm, diarrhea (54%) in the abemaciclib arm, and nausea (25%) in the merestinib arm. DLTs associated with hepatoxicity were observed in 3 of 4 patients in the abemaciclib lead-in cohorts. No DLTs or grade 3 or 4 hepatoxicity were reported in the concurrent abemaciclib arm. Pharmacokinetic characteristics were comparable with other PD-L1 inhibitors. One patient in each arm experienced a partial response per RECIST v1.1 lasting ≥7 months. CONCLUSIONS LY3300054 was well tolerated without unexpected safety concerns when administered alone or concurrently with ramucirumab, abemaciclib, or merestinib. Lead-in abemaciclib before combining with LY3300054 was not feasible due to hepatotoxicity. Durable clinical benefits were seen in all regimens.

Abstract
BACKGROUND & AIMS This study compared pharmacokinetics, symptomatic and endoscopic efficacy, safety, and immunogenicity of a subcutaneous formulation of the infliximab biosimilar CT-P13 (CT-P13 SC) vs intravenous CT-P13 (CT-P13 IV) in patients with inflammatory bowel disease (IBD). METHODS This randomized, multicenter, open-label, parallel-group, phase 1 study enrolled tumor necrosis factor inhibitor-naïve patients with active ulcerative colitis (total Mayo score 6-12 points with endoscopic subscore ≥2) or Crohn's disease (Crohn's Disease Activity Index 220-450 points) at 50 centers. After CT-P13 IV induction at Week (W) 0/W2, patients were randomized (1:1) to receive CT-P13 SC every 2 weeks (q2w) from W6 to W54 or CT-P13 IV every 8 weeks from W6 to W22. At W30, all patients receiving CT-P13 IV switched to CT-P13 SC q2w until W54. The primary endpoint was noninferiority of CT-P13 SC to CT-P13 IV for observed predose CT-P13 concentration at W22 (Ctrough,W22), concluded if the lower bound of the 2-sided 90% confidence interval (CI) for the ratio of geometric least-squares means exceeded 80%. RESULTS Overall, 66 and 65 patients were randomized to CT-P13 SC and CT-P13 IV, respectively. The primary endpoint of noninferiority was met with a geometric least-squares means ratio for Ctrough,W22 of 1154.17% (90% CI 786.37-1694.00; n = 59 [CT-P13 SC]; n = 57 [CT-P13 IV]). W30/W54 clinical remission rates were comparable between arms. Other efficacy, safety, and immunogenicity assessments were also broadly comparable between arms, including after switching. CONCLUSIONS The pharmacokinetic noninferiority of CT-P13 SC to CT-P13 IV, and the comparable efficacy, safety, and immunogenicity profiles, support the potential suitability of CT-P13 SC treatment in IBD.

Abstract
BACKGROUND In the primary analysis of the phase 3 MAIA trial (median follow-up 28·0 months), a significant improvement in progression-free survival was observed with daratumumab plus lenalidomide and dexamethasone versus lenalidomide and dexamethasone alone in transplantation-ineligible patients with newly diagnosed multiple myeloma. Here, we report the updated efficacy and safety results from a prespecified interim analysis for overall survival. METHODS MAIA is an ongoing, multicentre, randomised, open-label, phase 3 trial that enrolled patients at 176 hospitals in 14 countries across North America, Europe, the Middle East, and the Asia-Pacific region. Eligible patients were aged 18 years or older, had newly diagnosed multiple myeloma, had an Eastern Cooperative Oncology Group performance status score of 0-2, and were ineligible for high-dose chemotherapy with autologous stem-cell transplantation because of their age (≥65 years) or comorbidities. Patients were randomly assigned (1:1) using randomly permuted blocks (block size 4) by an interactive web response system to receive 28-day cycles of intravenous daratumumab (16 mg/kg, once per week during cycles 1-2, once every 2 weeks in cycles 3-6, and once every 4 weeks thereafter) plus oral lenalidomide (25 mg on days 1-21 of each cycle) and oral dexamethasone (40 mg on days 1, 8, 15, and 22 of each cycle; daratumumab group) or lenalidomide and dexamethasone alone (control group). Randomisation was stratified by International Staging System disease stage, geographical region, and age. Neither patients nor investigators were masked to treatment assignment. The primary endpoint was progression-free survival, which was centrally assessed, and a secondary endpoint was overall survival (both assessed in the intention-to-treat population). The safety population included patients who received at least one dose of the study treatment. The results presented here are from a prespecified interim analysis for overall survival, for which the prespecified stopping boundary was p=0·0414. This trial is registered with ClinicalTrials.gov, NCT02252172. FINDINGS Between March 18, 2015, and Jan 15, 2017, 952 patients were assessed for eligibility, of whom 737 patients were enrolled and randomly assigned to the daratumumab group (n=368) or the control group (n=369). At a median follow-up of 56·2 months (IQR 52·7-59·9), median progression-free survival was not reached (95% CI 54·8-not reached) in the daratumumab group versus 34·4 months (29·6-39·2) in the control group (hazard ratio [HR] 0·53 [95% CI 0·43-0·66]; p<0·0001). Median overall survival was not reached in either group (daratumumab group, 95% CI not reached-not reached; control group, 95% CI 55·7-not reached; HR 0·68 [95% CI 0·53-0·86]; p=0·0013). The most common (>15%) grade 3 or higher treatment-emergent adverse events were neutropenia (197 [54%] patients in the daratumumab group vs 135 [37%] patients in the control group), pneumonia (70 [19%] vs 39 [11%]), anaemia (61 [17%] vs 79 [22%]), and lymphopenia (60 [16%] vs 41 [11%]). Serious adverse events occurred in 281 (77%) patients in the daratumumab group and 257 (70%) patients in the control group. Treatment-related deaths occurred in 13 (4%) patients in the daratumumab group and ten (3%) patients in the control group. INTERPRETATION Daratumumab plus lenalidomide and dexamethasone increased overall survival and progression-free survival in patients ineligible for stem-cell transplantation with newly diagnosed multiple myeloma. There were no new safety concerns. Our results support the frontline use of daratumumab plus lenalidomide and dexamethasone for patients with multiple myeloma who are ineligible for transplantation.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) to date have demonstrated limited activity in advanced ovarian cancer (OC). Folate receptor alpha (FRα) is overexpressed in the majority of OCs and presents an attractive target for a combination immunotherapy to potentially overcome resistance to ICI in OCs. The current study sought to examine clinical and immunologic responses to TPIV200, a multiepitope FRα vaccine administered with programmed death ligand 1 (PD-L1) inhibitor durvalumab in patients with advanced platinum-resistant OC. METHODS Following Simon two-stage phase II trial design, 27 patients were enrolled. Treatment was administered in 28-day cycles (intradermal TPIV200 and granulocyte-macrophage colony-stimulating factor (GM-CSF) for 6 cycles and intravenous durvalumab for 12 cycles). Primary endpoints included overall response rate and progression-free survival at 24 weeks. Translational parameters focused on tumor microenvironment, PD-L1 and FRα expression, and peripheral vaccine-specific immune responses. RESULTS Treatment was well tolerated, with related grade 3 toxicity rate of 18.5%. Increased T cell responses to the majority of peptides were observed in all patients at 6 weeks (p<0.0001). There was one unconfirmed partial response (3.7%) and nine patients had stable disease (33.3%). Clinical benefit was not associated with baseline FRα or PD-L1 expression. One patient with prolonged clinical benefit demonstrated loss of FRα expression and upregulation of PD-L1 in a progressing lesion. Despite the low overall response rate, the median overall survival was 21 months (13.5-∞), with evidence of benefit from postimmunotherapy regimens. CONCLUSIONS Combination of TPIV200 and durvalumab was safe and elicited robust FRα-specific T cell responses in all patients. Unexpectedly durable survival in this heavily pretreated population highlights the need to investigate the impact of FRα vaccination on the OC biology post-treatment.

Efficacy of Evolocumab vs low-density lipoprotein cholesterol apheresis in patients with familial hypercholesterolemia and high cardiovascular risk (EVOLAFER01).
Torres, E, Goicoechea, M, Hernández, A, Rodríguez Ferrero, ML, García, A, Macías, N, Anaya, F
Journal of clinical apheresis. 2020;(1):9-17
Abstract
UNLABELLED Low-density lipoprotein (LDL) apheresis has been considered the last option to treat refractory hyperlipidemia in patients with familiar hypercholesterolemia (FH). Evolocumab is a monoclonal antibody which has shown significant reduction of low-density lipoprotein cholesterol (LDL-C) serum levels and cardiovascular events. The aim of the study was to examine the comparative impact of LDL-apheresis vs Evolocumab vs the combination of both LDL-apheresis and Evolocumab on lipid and lipoprotein parameters, and other metabolic/inflammatory measures. DESIGN OF THE STUDY Non-randomized open case series study of 10 adult patients diagnosed with FH already on long-term LDL-apheresis therapy. The study was developed in three consecutive phases to compare LDL-apheresis, Evolocumab treatment and the combination of both. Laboratory parameters were collected pre and post LDL-apheresis and before Evolocumab administration. The primary endpoint was the reduction of LDL-C during the three phases. RESULTS Reduction of LDL-C levels with Evolocumab were 31.4% vs LDL-apheresis from 153 ± 35 mg/dL to 105 ± 56 mg/dL (P < .001). Reduction of Lp(a) was also significantly higher with Evolocumab (45.5%) than LDL-apheresis from 36 (6-119) to 20 (3-41) mg/dL, P = .027. In addition, HDL-C and apo-A increased after Evolocumab treatment, from 41 ± 6 to 46 ± 8 mg/dL (P = .003) and from 124 ± 13 to 144 ± 25 mg/dL (P = .001), respectively. No changes in immunological or inflammatory parameters were observed and no serious adverse events were recorded. CONCLUSION Evolocumab reduces LDL-C and Lp(a) more effectively than LDL-apheresis and combination of Evolocumab plus LDL-apheresis could be a therapeutic alternative to get lower LDL-C and Lp(a) levels in patients with very high cardiovascular risk.

Abstract
BACKGROUND Effective adjuvant treatment after hepatectomy for hepatocellular carcinoma (HCC) is an important area of research. Radioactive iodine (131I)-labelled metuximab is a radiolabelled monoclonal antibody against the CD147 (also known as basigin or HAb18G) antigen that is expressed in HCC. We aimed to examine the role of 131I-metuximab as an adjuvant therapy after HCC resection. METHODS This randomised, controlled, multicentre, open-label, phase 2 trial was done at five medical centres in China. Patients aged 18-75 years who underwent curative-intent resection of histologically confirmed HCC expressing CD147 were randomly assigned (1:1) by a computer-generated random sequence, stratified by centre, to receive either adjuvant transarterial injection of one dose of 27·75 MBq/kg 131I-metuximab 4-6 weeks after the hepatectomy (treatment group) or no adjuvant treatment (control group). Patients and physicians were not masked to the study groups. The primary outcome was 5-year recurrence-free survival (RFS) in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT00819650. FINDINGS Between April 1, 2009, and Nov 30, 2012, 485 patients were screened for eligibility. 329 (68%) of these patients were excluded and 156 (32%) were randomly assigned to receive either 131I-metuximab (n=78) or no adjuvant treatment (n=78). The median follow-up was 55·9 months (IQR 18·6-79·4). In the intention-to-treat population, the 5-year RFS was 43·4% (95% CI 33·6-55·9) in the 131I-metuximab group and 21·7% (14·2-33·1) in the control group (hazard ratio 0·49 [95% CI 0·34-0·72]; Z=2·96, p=0·0031). 131I-metuximab-associated adverse events occurred within the first 4 weeks in 34 (45%) of 76 patients, seven (21%) of whom had grade 3 or 4 adverse events. These adverse events were all resolved with appropriate treatment within 2 weeks of being identified. INTERPRETATION Adjuvant 131I-metuximab treatment significantly improved the 5-year RFS of patients after hepatectomy for HCC tumours expressing CD147. This treatment was well tolerated by patients.

Abstract
IMPORTANCE Faricimab, the first bispecific antibody designed for intraocular use, simultaneously and independently binds and neutralizes angiopoietin 2 (Ang-2) and vascular endothelial growth factor A (VEGF-A). OBJECTIVE To assess the efficacy and safety of different doses and regimens of faricimab vs ranibizumab in patients with neovascular age-related macular degeneration (nAMD). DESIGN, SETTING, AND PARTICIPANTS AVENUE was a 36-week, multiple-dose-regimen, active comparator-controlled, double-masked, phase 2 randomized clinical study performed at 58 sites in the United States. Eligible participants were anti-VEGF treatment naive with choroidal neovascularization secondary to nAMD and best-corrected visual acuity (BCVA) Early Treatment Diabetic Retinopathy Study (ETDRS) letter score of 73 (Snellen equivalent, 20/40) to 24 (Snellen equivalent, 20/320). Data were collected from August 11, 2015, to January 12, 2017, with the final patient visit completed September 26, 2017. Data were analyzed from August 11, 2015, to October 4, 2019. INTERVENTIONS Patients were randomized 3:2:2:2:3 to receive ranibizumab, 0.5 mg every 4 weeks (arm A [n = 68]); faricimab, 1.5 mg every 4 weeks (arm B [n = 47]); faricimab, 6.0 mg every 4 weeks (arm C [n = 42]); faricimab, 6.0 mg every 4 weeks until week 12, then faricimab, 6.0 mg every 8 weeks (arm D [n = 47]); and ranibizumab, 0.5 mg every 4 weeks until week 8, then faricimab, 6.0 mg every 4 weeks (arm E [n = 69]). MAIN OUTCOMES AND MEASURES Mean change in BCVA from baseline to week 36, proportion of participants gaining at least 15 letters, BCVA of 20/40 or better or 20/200 or worse, and ocular coherence tomographic outcomes in anti-VEGF treatment-naive participants (arms A, B, C, D) and from weeks 12 to 36 in those with incomplete response (participants in arms A and E with week 12 BCVA ETDRS letter score of ≤68 [Snellen equivalent, 20/50 or worse]). RESULTS A total of 263 participants were included in the analysis (172 [65.4%] female; 258 [98.1%] white; mean [SD] age, 78.3 [8.7] years). At week 36, adjusted mean change in BCVA vs ranibizumab was 1.6 (80% CI, -1.6 to 4.7) letters for arm B (P = .52), -1.6 (80% CI, -4.9 to 1.7) letters for arm C (P = .53), and -1.5 (80% CI, -4.6 to 1.6) letters for arm D (P = .53). For arm E, adjusted mean change from week 12 was -1.7 (80% CI, -3.8 to 0.4) letters (P = .30). CONCLUSIONS AND RELEVANCE AVENUE did not meet its primary end point of superiority of faricimab over ranibizumab in BCVA at week 36. Although not superior to monthly ranibizumab as given in this trial, overall visual and anatomical gains noted with faricimab support pursuing phase 3 trials for a potential alternative to monthly anti-VEGF therapy. Faricimab showed no new or unexpected safety signals. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02484690.

Abstract
INTRODUCTION The phase 3 ALCYONE study demonstrated significantly longer progression-free and overall survival (PFS/OS) and higher overall response rates (ORR) with daratumumab plus bortezomib, melphalan, and prednisone (D-VMP) versus VMP alone in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). In Latin America, bortezomib- or thalidomide-based regimens remain standard of care (SoC) for this population. No head-to-head trials have compared D-VMP with SoC regimens used in Latin America. METHODS Propensity score matching (PSM) was used to control for baseline differences between patient populations and compare outcomes for D-VMP versus SoC regimens used in Latin America. Data for the D-VMP cohort were from the D-VMP arm of the ALCYONE trial (n = 350). Data for the SoC cohort were from the retrospective, observational Hemato-Oncology Latin America (HOLA) study, which included patients with NDMM who did not receive a transplant (n = 729). Propensity scores were estimated using logistic regression. Exact, optimal, and nearest-neighbor PSM were applied to pick the best-performing method. Doubly robust estimation was the base case, since some baseline imbalances persisted. RESULTS All 350 patients from the D-VMP arm of ALCYONE were included in OS/PFS analyses and 338 in ORR analysis; 478 and 324 patients, respectively, from HOLA were included in these analyses. Naïve comparison revealed important differences in baseline characteristics (age, chronic kidney disease, hypercalcemia, and International Staging System [ISS] stage). After nearest-neighbor matching, baseline characteristics, except ISS stage, were well balanced; comparisons favored D-VMP over SoC for OS (hazard ratio = 0.41; 95% confidence interval [CI] 0.25-0.66; P = 0.002) and PFS (hazard ratio = 0.48; 95% CI 0.35-0.67; P < 0.001). After exact matching, imbalances remained in age and ISS stage; comparisons favored D-VMP over SoC for ORR (odds ratio = 5.44; 95% CI 2.65-11.82; P < 0.001). CONCLUSION In transplant-ineligible patients with NDMM, D-VMP showed superior effectiveness versus bortezomib- and thalidomide-based regimens, supporting adoption of daratumumab-containing regimens in Latin America.

Abstract
IMPORTANCE Faricimab neutralizes angiopoietin-2 and vascular endothelial growth factor A via both simultaneous and independent binding. OBJECTIVE To evaluate extended dosing with faricimab, the first bispecific antibody designed for intraocular use, in patients with neovascular age-related macular degeneration. DESIGN, SETTING, AND PARTICIPANTS This phase 2 randomized clinical trial was a 52-week multicenter, active comparator-controlled, parallel-group study. Study participants were enrolled in 25 sites in the US from January and March 2017 with treatment-naive choroidal neovascularization secondary to neovascular age-related macular degeneration and best-corrected visual acuity (BCVA) Early Treatment Diabetic Retinopathy Study letter score of 73 (approximate Snellen equivalent, 20/40) to 24 (approximate Snellen equivalent, 20/320). Analysis began January 2017 and ended March 2018. INTERVENTIONS Participants were randomized 1:2:2 to receive intravitreal ranibizumab, 0.5 mg, every 4 weeks or faricimab, 6.0 mg, every 12 or 16 weeks. Participants in the faricimab arms initially received 4 monthly injections of faricimab. No rescue injections were allowed. Participants randomized to dosing every 16 weeks were assessed for disease activity at week 24 using prespecified criteria. Those with no active disease continued dosing every 16 weeks through trial end; participants with disease activity continued received dosing every 12 weeks. MAIN OUTCOMES AND MEASURES Mean change in BCVA from baseline at week 40. RESULTS Of 76 participants enrolled (mean [SD] age, 78.5 [8.5] years; age range, 56-94 years; 41 women [58%]; 69 white [97%]), 16 (21.0%) were randomized to ranibizumab every 4 weeks, 29 (38.2%) to faricimab every 12 weeks, and 31 (40.8%) to faricimab every 16 weeks. At week 24, 12 weeks after their last initiation injection, 65% (36 of 55) of all faricimab-treated participants had no disease activity. At week 40, adjusted mean BCVA gains from baseline (Early Treatment Diabetic Retinopathy Study letters) were +11.4 (80% CI, 7.8-15.0), +9.3 (80% CI, 6.4-12.3), and +12.5 (80% CI, 9.9-15.1) for the ranibizumab every 4 weeks, faricimab every 12 weeks, and faricimab every 16 weeks arms, respectively. Participants received a mean (SD) total of 12.9 (0.25), 6.7 (0.91), and 6.2 (0.93) injections, for the ranibizumab every 4 weeks, faricimab every 12 weeks, and faricimab every 16 weeks arms, respectively, through week 52. The secondary BCVA and anatomical imaging end points supported the primary end point and were comparable with ranibizumab every 4 weeks. No new or unexpected safety signals were identified. CONCLUSIONS AND RELEVANCE At week 52, faricimab dosing every 16 weeks and every 12 weeks resulted in maintenance of initial vision and anatomic improvements comparable with monthly ranibizumab. These results suggest a role for simultaneous neutralization of angiopoietin-2 and vascular endothelial growth factor A in providing sustained efficacy through extended durability, warranting further investigation.
