|---|---|---|---|
| Primary | Annualized Rate of Vaso-occlusive Crisis (VOC) Events Leading to a Healthcare Visit | 1 year | VOC is defined as pain crisis (defined as an acute onset of pain for which there is no other medically determined explanation other than vaso-occlusion) which requires therapy with oral or parenteral opioids or parenteral NSAID as well as other complicated crisis such as acute chest syndrome (ACS), priapism and hepatic or splenic sequestration. Healthcare visit is defined as any visit to a medical facility such as emergency room (ER), hospital and/or office visit, which includes pain management of VOC in situ. Annualized rate of corresponding VOC events = (Number of corresponding VOC events \* 365)/(number of days in the observation period). Observation period = time from date of randomization to minimum of (last dose date until treatment discontinuation + 27 days, date of initiation or discontinuation of HU/HC or L-Glutamine (or other therapies such as Voxelotor and erythropoietin therapies to treat SCD and/or to prevent/reduce VOCs), date of randomization + 365 days). |
| Secondary | Annualized Rate of All VOCs Leading to a Healthcare Visit and Treated at Home Over the First-year Post Randomization (Key Secondary) | 1 year | VOCs are based on documentation by provider following contact with participant. VOC:pain crisis requiring therapy with oral/parenteral opioids or parenteral NSAID as well as other complicated crisis such as acute chest syndrome, priapism and hepatic or splenic sequestration. Healthcare visit:a visit to a medical facility (ER, hospital \&/or office visit resulting in pain management of VOC. Managed at home: no visit to any medical facility \&/or healthcare professional to receive treatment for VOC. Healthcare contact for medical advice is allowed. Annualized rate of corresponding VOC events = (# of corresponding VOC events \* 365)/(# of days in observation period). Observation period = time from date of randomization to minimum of (last dose date until treatment discontinuation + 27 days, date of initiation or discontinuation of HU/HC or L-Glutamine (or other therapies such as Voxelotor \& erythropoietin therapies to treat SCD \&/or to prevent/reduce VOCs), date of randomization + 365 days) |
| Secondary | Annualized Rate of All VOCs Leading to a Healthcare Visit and Treated at Home Over 5 Years Post Randomization (Key Secondary) | 5 years | To compare the efficacy of 5.0 mg/kg vs placebo \& 7.5 mg/kg vs placebo on the annualized rate of all VOCs based on documentation by provider following contact with participant. VOC is defined as pain crisis (an acute onset of pain for which there is no other medically determined explanation other than vaso-occlusion) requiring therapy with oral/parenteral opioids or parenteral NSAID as well as other complicated crisis such as acute chest syndrome, priapism and hepatic or splenic sequestration. Healthcare visit is defined as a visit to a medical facility (emergency room, hospital and/or office visit resulting in pain management of VOC. Managed at home is defined as no visit to any medical facility and/or healthcare professional to receive treatment for VOC. Healthcare contact for medical advice is allowed. The annualized rate of VOC leading to healthcare visit is the number of VOC leading to healthcare visit multiplied by 365 \& divided by the number of days in observation period. |
| Secondary | Mean Duration of VOCs Leading to a Healthcare Visit Over the First-year Post Randomization | 1 year | To assess the duration of VOCs leading to healthcare visit in each group. Mean duration of VOC per participant is defined as the average duration of all individual episodes of VOCs leading to healthcare visits of a given participant (a VOC duration is defined as end date of the VOC - start date of the VOC + 1). Participants with no VOC leading to healthcare visits have been excluded. |
| Secondary | Number of Participants Free From VOCs Leading to a Healthcare Visit Over the First-year Post Randomization | 1 year | To assess the number of participants free from VOCs leading to healthcare visit. VOC is defined as pain crisis (defined as an acute onset of pain for which there is no other medically determined explanation other than vaso-occlusion) which requires therapy with oral or parenteral opioids or parenteral NSAID as well as other complicated crisis such as acute chest syndrome (ACS), priapism and hepatic or splenic sequestration. A participant is free from VOC if they do not have a VOC crisis. |
| Secondary | Percentage of Participants Free From VOCs Leading to a Healthcare Visit Over the First-year Post Randomization | 1 year | To assess the percentage of participants free from VOCs leading to healthcare visit. VOC is defined as pain crisis (defined as an acute onset of pain for which there is no other medically determined explanation other than vaso-occlusion) which requires therapy with oral or parenteral opioids or parenteral NSAID as well as other complicated crisis such as acute chest syndrome (ACS), priapism and hepatic or splenic sequestration. A participant is free from VOC if they do not have a VOC crisis. |
| Secondary | Time to First and Second VOCs Leading to a Healthcare Visit Over the First-year Post Randomization | 1 year | To assess the time to first and second VOC leading to healthcare visit in each group.
