A Phase I Study to Assess the Safety of Pegcetacoplan (APL-2) as an Add-On to Standard of Care in Subjects With PNH

December 14, 2020 updated by: Apellis Pharmaceuticals, Inc.

An Open Label, Single and Multiple Ascending Dose Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of APL-2 as an Add-On to Standard of Care in Subjects With Paroxysmal Nocturnal Hemoglobinuria (PNH).

This study will be the initial exploration of pegcetacoplan in patients with PNH. The assessments of the safety, tolerability, PK, and PD following administration of single and multiples doses of pegcetacoplan will guide decisions to further develop the drug.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Subjects With Treatment-Emergent Adverse Events (TEAEs), Including by Severity, During Single-dose Phase
Time Frame: From single dose of study drug (Day 1) up to 30 days
TEAEs were defined as AEs that developed or worsened after first dose of study drug (Day 1), and up to 30 days after last dose of study drug. The Investigator assessed AEs for severity and relatedness to study drug. AEs were graded according to the Common Terminology Criteria for Adverse Events (CTCAE, v4.03) based on: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life-threatening; Grade 5: Death related to AE.
From single dose of study drug (Day 1) up to 30 days
Number of Subjects With TEAEs, Including by Severity, During Multiple-dose Phase
Time Frame: From first dose of study drug up to 30 days after last dose of study drug (Cohorts 1-3: up to 58 days; Cohort 4: up to 759 days).
TEAEs were defined as AEs that developed or worsened after first dose of study drug (Day 1), and up to 30 days after last dose of study drug. The Investigator assessed AEs for severity and relatedness to study drug. AEs were graded according to CTCAE, v4.03 based on: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life-threatening; Grade 5: Death related to AE.
From first dose of study drug up to 30 days after last dose of study drug (Cohorts 1-3: up to 58 days; Cohort 4: up to 759 days).
Area Under the Curve (AUC) From Time 0 to the Last Measurable Concentration (AUC0-t) Over the Multiple Dosing Phase for Cohort 4
Time Frame: Blood samples for PK assessment were collected pre-dose and 4 hours post dose on Day 1 and pre-dose (trough) on Day 2 and up to Day 785.
Assessment of AUC0-t of pegcetacoplan over the multiple dosing phase, estimated using a non-compartmental approach and calculated by the linear-log trapezoidal method. Pegcetacoplan pharmacokinetic (PK) parameters were summarized for Cohort 4 only.
Blood samples for PK assessment were collected pre-dose and 4 hours post dose on Day 1 and pre-dose (trough) on Day 2 and up to Day 785.
Maximum Pre-dose Serum Concentration (Ctrough,Max) Over the Multiple Dosing Phase for Cohort 4
Time Frame: Blood samples for PK assessment were collected pre-dose and 4 hours post dose on Day 1 and pre-dose (trough) on Day 2 and up to Day 785.
Assessment of Ctrough,max of pegcetacoplan over the multiple dosing phase, estimated using a non-compartmental approach. Pegcetacoplan PK parameters were summarized for Cohort 4 only. Ctrough,max was calculated for both 270 mg/day and 360 mg/day where subjects received both doses. Note: 1 subject in Cohort 4 who was receiving 360 mg/day was granted Sponsor and institutional review board approval to increase the dose further to the equivalent of 440 mg/day and Ctrough,max is also reported for this dose.
Blood samples for PK assessment were collected pre-dose and 4 hours post dose on Day 1 and pre-dose (trough) on Day 2 and up to Day 785.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
