TRIAL DESCRIPTION
Public title GBT2104-132
Official scientific title A Randomized, Double-blind, Placebo-controlled, Multicenter Study of a Single Dose of Inclacumab to Reduce Re-admission in Participants with Sickle Cell Disease and Recurrent Vaso-occlusive Crises
Brief summary describing the background and objectives of the trial The primary objective of this study is to evaluate the safety and efficacy of a single dose of inclacumab compared to placebo to reduce the incidence of re-admission to a healthcare facility for a vaso-occlusive crisis (VOC) after an admission for an index VOC in participants with sickle cell disease (SCD). Additional objectives of the study are to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of inclacumab, the presence of anti-drug antibodies (ADAs), and changes in quality of life (QOL).

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group Inclacumab 30mg/kg administered IV on Day 1 The total study duration for each participant will be variable based on the time from the start of the index VOC admission to Day 1. For example, if a participant begins screening at the start of a 10-day index VOC admission and is randomized the day of their index VOC resolution, the study duration would be 170 days, including a 10-day Screening period, a 90-day treatment period, and a 70-day (10 week) follow-up period. The inclacumab drug substance is manufactured by fermentation cell culture using Chinese hamster ovary (CHO) cells followed by purification. The drug substance and drug product are manufactured in accordance with Good Manufacturing Practice (GMP). Inclacumab drug product is a sterile, clear to opalescent liquid concentrate for infusion with an approximate pH of 5.5 provided in colorless, 10 mL single-use vials. Each vial contains 500 mg of inclacumab and the following excipients: L histidine-acetate, sucrose, and poloxamer 188. 140
Control Group Placebo Placebo administered IV on Day 1 as a single dose. 90-day treatment period The placebo for inclacumab to be used in this study will be a matched placebo for IV infusion with the same excipients found in inclacumab without the active product. 140 Placebo

1. Participant has an index VOC. The index VOC is any VOC that required admission to a healthcare facility and treatment with parenteral pain medication. An admission for the index VOC includes: a. A hospital admission, or b. An admission to an emergency room, observation unit, or infusion center for ≥ 12 hours, or c. 2 visits to an emergency room, observation unit, or infusion center over a 72 hour period. for an acute episode of pain with no other cause other than a vaso-occlusive event that includes the following: - Uncomplicated VOC, - Acute chest syndrome (ACS), - Acute hepatic sequestration, - Acute splenic sequestration, or - Priapism. 2. Participant has a confirmed diagnosis of SCD any genotype). Documentation of SCD genotype is required and may be based on documented history of laboratory testing or confirmed by laboratory testing at Baseline. 3. Participant is male or female, ≥ 12 years of age at the time of informed consent. 4. Participant is able to complete screening and receive study drug within 5 days following investigator-assessed resolution of index VOC (for example, hospital discharge, discontinuation of parenteral pain medication, or transition to oral pain medication). Participant has experienced between 2 and 10 VOCs within the 12 months prior to Screening as determined by documented medical history. The index VOC is not to be considered as one of the 2 to 10 events. A prior VOC is defined as an acute episode of pain that: a.

Participant has been treated with another investigational agent within 30 days or 5 half lives of the investigational agent (whichever is greater) prior to Screening. Participant has had a major surgery within 8 weeks prior to the Screening Visit. 14. Participant is pregnant, breastfeeding, or planning to become pregnant during the 90-day treatment period. 15. Participant, parent, or legal guardian are unlikely to comply with the study procedures. 16. Participant has other medical, or psychological, or behavioral conditions that, in the opinion of the Investigator, would: confound or interfere with evaluation of safety, efficacy, and/or PK of the investigational drug; prevent compliance with the study protocol; preclude informed consent; or,render the participant, parent, or legal guardian unable/unlikely to comply with the study procedures. 80 and over: 80+ Year,Adolescent: 13 Year(s)-17 Year(s),Adult: 18 Year(s)-44 Year(s),Aged: 65 Year(s)-79 Year(s),Middle Aged: 45 Year(s)-64 Year(s) 12 Year(s) 85 Year(s) Both

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome The primary endpoint for this study is, following an index VOC, the proportion of participants with at least 1 VOC that required admission to a healthcare facility and treatment with parenteral pain medication within 90 days of randomization. An admission for a VOC includes: • A hospital admission, or • An admission to an emergency room, observation unit, or infusion center for ≥ 12 hours, or • 2 visits to an emergency room, observation unit, or infusion center over a 72 hour period. for an acute episode of pain with no other cause other than a vaso-occlusive event that includes the following: • Uncomplicated VOC, • Acute chest syndrome (ACS), • Acute hepatic sequestration, • Acute splenic sequestration, or • Priapism. The definition of the index VOC requiring admission is the same as the primary endpoint VOC requiring admission. To ensure consistency across study sites, all on-study VOCs reported by the study investigators will be adjudicated by an independent, blinded panel comprised of experts in SCD. The primary efficacy analysis will be performed on adjudicated data. Within 90 days of randomization
Secondary Outcome The secondary efficacy endpoints of the study are the following: • Time to first VOC that required admission to a healthcare facility and treatment with parenteral pain medication within 90 days of randomization. • Proportion of participants with at least 1 VOC that required admission to a healthcare facility and treatment with parenteral pain medication within 30 days of randomization. • Rate of VOCs leading to a healthcare visit (hospital, emergency room, clinic visit, or remote contact with a healthcare provider) that requires parenteral pain medication (eg, parenteral narcotic agents or parenteral nonsteroidal anti-inflammatory drugs [NSAIDs]), or an increase in treatment with oral narcotics within 90 days following randomization. Within 90 days following randomization.
