administered and then discontinued, at least 3 months must have elapsed since last
dose of HU

- If subject has been transfused in the 3 months prior to screening, then Hb A level <
20% at screening

- Baseline Hb F level obtained within 14 days prior to randomization

- Able to swallow tablets

- Able and willing to give informed consent and/or assent

- If subject is a woman of child-bearing potential (WCBP), she must have a negative
serum pregnancy test within 14 days of first dose of HQK-1001 and a negative urine
pregnancy test prior to dosing on Day 1

- If a subject is a WCBP, she must agree to use an effective form of contraception
starting at screening and for one month after HQK-1001 discontinuation

- Sexually active male subjects who have not had a vasectomy must agree to use latex

to screening

- Serum amylase levels > 1.5x ULN

- Serum lipase level > 1.5x ULN

- A serious, concurrent illness that would limit ability to complete or comply with the
study requirements

- An acute illness (e.g., febrile, GI, respiratory) within 72 hours prior to screening

- History of syncope, clinically significant dysrhythmias or resuscitation from sudden
death due to SCD-related complication

- Symptomatic peptic ulcer, hiatus hernia, or gastroesophageal reflux disease (GERD)

- History of pancreatitis
