Adjudicated Acute Pancreatitis Mean Event Rate Per 100 Subject-Years During the Treatment Period (Week 1 Through Week 53) in Subjects With Prior History of Pancreatitis [22] | ||||||||||||
End point description |
All AEs & SAEs that consistently occurred during study with an event of acute pancreatitis were adjudicated by a blinded independent committee according to Atlanta classification of acute pancreatitis as outlined in the Acute Pancreatitis Adjudication Committee (PAC) Charter. These events were categorized: documented pancreatitis, probable pancreatitis, possible pancreatitis, unable to adjudicate, no diagnosis of acute pancreatitis. Adjudicated event rate represents average number of events per 100 subject-years during treatment period. FAS included all subjects that were randomly assigned to treatment and received at least 1 dose of olezarsen or placebo. 'Subjects analyzed' indicates the number of subjects with a history of pancreatitis within 10 years prior to screening. As prespecified in the protocol, data for this endpoint was collected and reported in a pooled manner for olezarsen (combined Olezarsen 50 mg + Olezarsen 80 mg).

07 Aug 2020 |
Added 50 mg every 4 weeks dosing cohort, with target enrollment of 30 subjects in each cohort. Each cohort was randomized 2:1 to receive olezarsen or matching placebo every 4 weeks. Updated Study Design and Treatment Schema to include 2 study cohorts (Cohorts A and B). Updated secondary objectives to specify the analysis time points for each objective. Added secondary endpoints for percentage change from Baseline in fasting TG at 12 months and for proportion of subjects who achieve ≥ 70% reduction in fasting TG from Baseline. |
||
29 Oct 2020 |
Updated dosing for Cohort A to continue on 50 mg every 4 weeks or placebo up to Month 12 instead of up-titration to 80 mg every 4 weeks at Month 6. Added Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form v2.0 Cognitive Function 4a as optional evaluation. Updated Exclusion Criterion 3 to allow up to 2 retests at Screening and Qualification for patients with platelet counts < 100,000 per cubic millimeter (mm^3). Removed exclusion criterion related to history of oligonucleotide associated platelet count < 75,000/mm3 (Exclusion Criterion 6 in original Study Protocol). Simplified Inclusion Criterion 7 by cross-referencing section on patient-reported outcomes (PROs). Added language for lab alerts to clarify safety monitoring criteria. Clarified confirmation window, criteria to restart treatment for patients with low platelet count. Updated stopping rules for liver chemistry elevations to note that ALT and AST levels were to be ≤ 3*ULN before treatment can be restarted in patients meeting liver stopping rules. An FCS Symptoms Two Week Recall questionnaire was added at Screening to obtain symptom data prior to randomization into the study. |
||
21 Dec 2020 |
Clarified Exclusion Criterion 11 does not apply to vaccines (both mRNA and Viral Vector). Added sections on Additional Risks During the COVID-19 Pandemic and Allowances in the Circumstance of a Public Health Emergency. Added section on monitoring for LDL-C elevations. Added RDW and MPV to hematology laboratory analytes. |
||
11 Mar 2021 |
Updated Exclusion Criterion 3e (and corresponding renal function safety monitoring criteria) to UPCR of ≥ 0.5 mg/mg or UACR of ≥ 300 mg/g. Added COVID-19 infection not resolved by Study Day 1 to Exclusion Criterion 6. Updated safety monitoring for renal function including UACR (>300 mg/g, or > 50% Baseline whichever was greater) and UPCR levels (> 0.500 mg/mg, or > 50% Baseline whichever was greater). Updated LDL-C thresholds in monitoring criteria (and added conditional to > 100 mg/dL criterion to include either T2DM or CAD with Baseline LDL-C > 100 mg/dL). Added Day 15 ADA and PK sample collections, ADA sample collections on Follow-up Day 4 and 8, and Day 169 PK sample collection at 2h ± 15 min post-dose. |
||
16 Apr 2021 |
Updated Exclusion Criterion 11 to allow a 4-month washout for treatment with a single dose of an oligonucleotide plus a “booster” (i.e., second) dose and to clarify this exclusion does not apply to any vaccine. Clarified conditions under which local repeat testing for hematology samples may be conducted. Clarified that site of injection for study drug should not be the same as injection site for COVID-19 vaccine. Clarified that Day 15 PK sample was collected Anytime rather than Pre-dose. |
||
25 Oct 2021 |
Added ER visit to the definition of history on pancreatitis for Inclusion Criterion 5. Increased enrollment cap for patients without a recorded history of pancreatitis. Change/Rationale for Amendments. Removed GLP agonists from Exclusion Criteria 10b and 12b. Changed washout period for oligonucleotides in Exclusion Criterion 11 to 4 months prior to Screening, or 5 half-lives, whichever is longer. Clarified that race and ethnicity data were to be included in demographic information collected at screening. Clarified that the collection period of pancreatitis medical history was within 10 years prior to Screening with independent adjudication of information collected about events within 5 years prior to Screening. Clarified treatment of redacted documents during database lock. Clarified landmark visits in appendices. |
||
26 Oct 2022 |
Added secondary endpoints for adjudicated pancreatitis event rates from Weeks 13 to 53. Clarified blinding to lipid data in study design. Added allowance for COVID-19 antiviral treatments under EUA outside of trial. Added true abstinence for males as acceptable method of contraception in the inclusion criteria and prevention of pregnancy sections. Adjusted contraceptive requirement period from 30 weeks to 17 weeks post-final dose based on updated PK modeling, fertility/early embryonic development study data. Provided additional guidance on highly effective contraception. Changed platelet count monitoring from weekly to every 2 weeks with platelet count ≥ 100,000/mm3 to < 140,000/mm3. Added language to note that patients who experience persistent or increasing constitutional symptoms should be tested for ADA. Added language to clarify safety monitoring for hypersensitivity reactions (symptoms, procedures). Clarified that spontaneous abortion/miscarriage is an SAE. Added 2 new secondary endpoints for adjudicated acute pancreatitis event rate to be measured from Week 13 to 53, and with ≥ 2 events of adjudicated acute pancreatitis in 5 years prior to enrollment. Added language clarifying that urine collection should not be performed during menstruation. |
||
19 Jun 2023 |
Added secondary endpoints measuring percent change in apoC-III and non-HDL-C, and updated the order of the study objectives. Clarified symptoms of hypersensitivity reactions and applicable lab assessments for monitoring. Updated AESI definitions to include pre-treatment to avoid a hypersensitivity reaction. Removed requirement for at least 1 post-Baseline TG assessment from Full Analysis Set definition. Updated secondary endpoint testing sequence. Clarified that sensitivity analysis in Per Protocol Set would occur for primary analysis, and secondary endpoints would be assessed in the Full Analysis Set alone. |
||
02 Aug 2023 |
Added secondary endpoints for adjudicated acute pancreatitis event rates during Treatment Period (Weeks 1 to 53) and from Weeks 13 to 53 in a subset of the Full Analysis Set with prior history of pancreatitis in 10 years prior to Screening. Revised secondary endpoints containing cutoff fasting TG ≤ 750 mg/dL to cutoff of ≤ 880 mg/dL (per inclusion criteria at screening). |
