P-selectin is an adhesion molecule expressed on activated vascular endothelial cells and platelets. Sudden cardiac death (SCD) is most commonly secondary to sustained ventricular arrhythmias (VAs). The efficacy and safety of crizanlizumab was studied in a 52-week, randomized, multicenter, placebo-controlled, double-blind, Phase II, clinical trial SUSTAIN (NCT01895361). In total, 82 patients (62.1%) were using concomitant HU at baseline. The procedures for the SUSTAIN study have been described in detail.17 In brief, patients received placebo or crizanlizumab at a dose of 2.5 or 5 mg/kg, administered intravenously 14 times over 52 weeks (2 loading doses in the first month followed by monthly infusions thereafter). Patients were randomized by an interactive voice or web response system to receive crizanlizumab 2.5 mg/kg, crizanlizumab 5 mg/kg, or placebo. The annual rate of uncomplicated SCPC at 5.0 mg/kg vs. placebo was reduced by 62% (medians of 1.1 vs. 2.9, p = 0.015). Clinical trials are underway using different gene transfer vectors and cassettes. The SUSTAIN study will form the basis of health authority submissions, although crizanlizumab in the treatment of patients with SCD will continue to be explored in additional studies. Thus, HU primarily targets RBCs, whereas crizanlizumab is targeting the vasculature.

In contrast, crizanlizumab targets intercellular adhesion including RBCs, platelets, neutrophils and endothelial cells. n = 32bb Number of patients included in the subgroup who experienced any VOC during the SUSTAIN study. Patients were randomized to receive placebo, 2.5 mg/kg or 5.0 mg/kg SelG1; patients received their initial dose, a dose 14 days later, and then every 4 weeks through week 50 for a total of 14 doses. o Data from the Hospital Episode Statistics (HES) database was used to estimate the risk of acute SCD-related complications or death associated with varying frequency of VOC.

The safety profile of crizanlizumab 5 mg/kg vs placebo in the SUSTAIN study has previously been discussed17 and this analysis did not identify any new safety concerns for crizanlizumab 5 mg/kg. It should be noted that these data were generated through a post hoc analysis of a study that was not powered to detect differences between patient subgroups; caution is therefore advised when interpreting these data. Introduction: Acute painful episodes, frequently called sickle cell-related pain crises (SCPC), are a substantial cause of morbidity in sickle cell disease (SCD). The primary endpoint was the annual rate of VOC with crizanlizumab vs placebo. That dose was shown to lower the frequency of annual VOCs in SCD patients in the company’s Phase 2 SUSTAIN (NCT01895361) trial. The trial enrolled 198 people with SCD, age 16 and up, with a history of frequent VOCs (between two and 10 episodes in the year before starting the study). Chronic inhibition of P-selectin with once a month IV dosing of SelG1 represents a novel and potentially new disease-modifying, prophylactic treatment option for patients with SCD. No evaluation of crizanlizumab 2.5 mg/kg was included in this analysis because the primary endpoint of the study was only met with the 5 mg/kg dose and therefore this is the dose for which further clinical development is planned. n = 31bb Number of patients included in the subgroup who experienced any VOC during the SUSTAIN study.

This trial data availability is according to the criteria and process described on www.clinicalstudydatarequest.com. In conclusion, this post hoc descriptive analysis of the phase 2 SUSTAIN study demonstrated that crizanlizumab increases the likelihood of being VOC event‐free and delays time‐to‐first VOC across all subgroups assessed. No treatment‐related AEs led to death. In these two trial arms, 62.9% had two to four VOC crises in the year before the study’s start, and 37.1% between five and 10. Findings for time‐to‐second VOC were similar to those observed for time‐to‐first VOC. Working off-campus? In almost all the subgroups evaluated, crizanlizumab increased the time‐to‐first VOC vs placebo. The purpose of this study is to compare the efficacy and safety of 2 doses of crizanlizumab (5.0 mg/kg and 7.5 mg/kg) versus placebo in adolescent and adult sickle cell disease (SCD) patients with history of vaso-occlusive crisis (VOC) leading to healthcare visit. Adakveo, a man-made antibody, works to block the activity of P-selectin, an adhesion protein that makes sickled blood cells more sticky and more likely to clog blood vessels, causing inflammation and pain crises. Safety assessments included frequency of treatment‐emergent adverse events (AEs) and treatment‐emergent serious adverse events (SAEs). The study will enroll up to 45 patients and follow patients for approximately two years after infusion. CLIMB-SCD-121: An ongoing Phase 1/2 open-label trial, designed to assess the safety and efficacy of a single dose of CTX001 in patients ages 18 to 35 with severe SCD. Although hydroxyurea (HU) is known to decrease the frequency of SCPC in sickle cell anemia, many patients continue to experience acute painful episodes despite such therapy. However, we must also pursue avenues through which we can do the most good for the most people alive today. Methods: We conducted a randomized, double-blind, placebo-controlled, multinational study. SCD (n=121) was assessed over a median follow-up of 1 year. Time to first SCPC at 5.0 mg/kg vs. placebo was increased 2.9-fold (medians of 4.1 vs. 1.4 months, p = 0.001, Fig. The rates of treatment‐emergent adverse events were similar between treatment arms across all subgroups. Abbreviations: HbSS, hemoglobin S; HU, hydroxyurea; VOC, vaso‐occlusive crisis. SUCCESSOR is a retrospective cohort study of adult patients (≥18 years old) who participated in the SUSTAIN study in the United States to evaluate outcomes related to SCD up to 52 weeks following their completion of the trial.

Gene therapies are being developed, and several are now in various stages of early-phase human clinical trials. The rates of treatment‐related (according to investigator judgment) AEs and SAEs were higher in patients treated with crizanlizumab than with placebo, across all subgroups, although the incidence of AEs leading to discontinuation was generally low in both dose groups (0%‐8.0% in the crizanlizumab arm vs 0%‐8.7% in the placebo arm across all subgroups). 2).

Official Title: A Phase II, Multicenter, Randomized, Placebo-Controlled, Double-Blind, 12-Month Study to Assess Safety and Efficacy of SelG1 With or Without Hydroxyurea Therapy in Sickle Cell Disease Patients With Sickle Cell-Related Pain Crises. Sickle cell disease (SCD) is a genetic disorder that predominantly affects individuals of African descent.1 It is characterized by the presence of sickle hemoglobin (HbS), which polymerizes upon deoxygenation, damaging erythrocytes and potentially leading to vaso‐occlusion, multi‐organ damage, and early death.2 Painful vaso‐occlusive crises (VOCs), also known as sickle cell pain crises, are the hallmark of SCD and are the primary cause of hospitalization in SCD.3 VOCs cause pain in the extremities, back, abdomen or chest, and can vary in intensity from mild to excruciating.4 Patients with SCD and frequent VOCs may experience problems with low self‐esteem, anxiety, depression, dissatisfaction with body image, poor school performance, social isolation, decreased participation in normal daily activities, and poor peer and family relationships.4, The most common SCD genotype is homozygous hemoglobin S (HbSS) which, along with sickle β0‐thalassemia (HbSβ0), is generally considered to be the most clinically severe. Patients using concomitant HU were included if they had been receiving HU treatment for ≥6 months and at a stable dose for at least the previous 3 months; these patients were not allowed to have HU dose adjustments during the study, except for safety reasons (eg, dose interruption/reduction because a patient was not tolerating HU therapy). In SUSTAIN, patients with SCD were randomized to crizanlizumab 2.5 mg/kg, crizanlizumab 5 mg/kg, or placebo intravenously 14 times over 52 weeks. Of these patients, more had experienced 2‐4 VOCs (n = 83/132, 62.9%) than 5‐10 VOCs in the year prior to study (n = 49/132, 37.1%). P-selectin, an adhesion molecule expressed on activated vascular endothelial cells and platelets, facilitates cell-to-cell and cell-to-endothelium interactions that are involved in the pathogenesis of VOC in SCD. Descriptive statistics were used to summarize patient demographics and baseline characteristics in the ITT population, and frequency of AEs and SAEs in the safety population, which included all randomized patients who received at least 1 dose of either crizanlizumab 5 mg/kg or placebo. 33 The SUSTAIN trial, a multicenter randomized double blind study, showed that crizanlizumab decreased the incidence of VOC by 45% in patients with or without HU. ZZ performed the analyses and contributed to the interpretation of the findings presented.

Patients were excluded if they were undergoing long‐term, RBC transfusion therapy. 1) and time to second SCPC was increased 2.0-fold (medians of 10.3 vs. 5.1 months, p = 0.022, Fig. The most common genotype was HbSS (94/132, 71.2%); the remaining non‐HbSS patients had HbSC, HbSβ0, HbSβ+, or rare genotypes. The primary endpoint, the annual rate of SCPC in the ITT population at 5.0 mg/kg vs. placebo, was reduced 47% (medians of 1.6 vs. 3.0, p = 0.010, Table 1). n = 11bb Number of patients included in the subgroup who experienced any VOC during the SUSTAIN study. It is a key molecule in the initiation of leukocyte rolling on the vessel wall that leads to firm attachment and extravasation to underlying tissues during inflammation. SUSTAIN was a 52-week pivotal SCD study that evaluated clinically meaningful end points 1,2 Study description. This pattern of response was also apparent in patients with 2‐4 VOCs in the previous year, no concomitant HU use, and non‐HbSS genotype. Over the course of the study, a greater proportion of patients in the crizanlizumab group (n = 24/67; 35.8%) did not experience a VOC, compared with patients in the placebo group (n = 11/65; 16.9%). Five deaths occurred during the study, 2 at 5.0 mg/kg, 1 at 2.5 mg/kg and 2 in placebo; no deaths were deemed related to study drug. Rollins:Selexys Pharmaceuticals: Equity Ownership, Other: Previous Employment. Although PSGL‐1 is not present on normal erythrocytes, sickled red blood cells (RBCs) are known to have glycoproteins on their cell surface that can mimic the P‐selectin ligand and mediate adherence to activated endothelial cells expressing P‐selectin.15, 16, Crizanlizumab is a humanized, anti‐P‐selectin monoclonal antibody.17 The 52‐week, phase 2 SUSTAIN study demonstrated that crizanlizumab has a potentially disease‐modifying effect when used for the prevention of VOCs in patients with SCD.17 In this study, crizanlizumab 5 mg/kg significantly reduced the frequency of VOCs by 45% (P = .01), significantly delayed the median time‐to‐first VOC by 2.7 months (P = .001) and second VOC by 5.2 months (P = .02), and appeared to decrease the annualized median rate of days hospitalized (for any cause) by 42% (4.00 vs 6.87 days) vs placebo in SCD patients aged ≥16 years, although the difference was not statistically significant due to large variability (P = .45) but may be considered clinically relevant.17. Hydroxyurea for sickle cell anemia: what have we learned and what questions still remain? The primary endpoint was the annual rate of VOC with crizanlizumab vs placebo.
