Ages Eligible for Study:   12 Years to 60 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Established diagnosis of SCD
  • Males and females between 12 and 60 years of age, inclusive
  • At least 3 episodes of a SCD-related crisis or complication in the 3 years prior to screening OR 1 episode of acute chest syndrome in the 5 years prior to screening
  • If receiving hydroxyurea, must be receiving a stable dose for at least 6 months prior to screening
  • If hydroxyurea treatment has been discontinued, at least 3 months have elapsed since last dose
  • If transfusion in the 4 months prior to screening, then HbA level < 20% at screening
  • Average of the initial two HbF levels ≥ 2.0 % within ≤ 7 days prior to the initial dose of HQK-1001. The two must be obtained ≥ 24 hours apart
  • Ability to swallow tablets
  • Able and willing to give informed consent and assent (if applicable)
  • If subject is a woman of child-bearing potential (WCBP), she must have a negative serum pregnancy test within 7 days of first dose of HQK-1001
  • If a subject is a WCBP, she must agree to use an effective form of contraception within 7 days of the initial dose of HQK-1001 and for one month after HQK-1001 discontinuation
  • Sexually active male subjects (with WCBP partners) must agree to use latex condoms or ensure that their partner(s) use an effective form of contraception
  • In the view of the Investigator, subject is able and willing to comply with necessary study procedures

Exclusion Criteria:

  • More than 4 hospitalizations for acute sickle cell related events in the previous 12 months prior to screening
  • Pulmonary hypertension requiring oxygen therapy
  • QTc > 450 msec (male) or 470 msec (female) on screening ECG (QT corrected by Fridericia's formula)
  • Assigned to a regular transfusion program
  • Use of erythropoiesis stimulating agents within 90 days of screening
  • ALT > 3x upper limit of normal (ULN)
  • Serum creatinine > 1.2 mg/dL
  • A serious, concurrent illness that would limit ability to complete or comply with the study requirements
  • An acute vaso-occlusive event within 3 weeks prior to screening
  • Creatine phosphokinase (CK) > 20% above the ULN
  • 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
  • Chronic opiate use, which, in the view of the Investigator, could confound evaluation of an investigational drug
  • Current abuse of alcohol or drugs
  • Received another investigational agent within 4 weeks or 5 half-lives, whichever is longer, prior to screening
  • Currently pregnant or breast feeding a child
  • Known infection with HIV-1
  • Infection with hepatitis B or hepatitis C, such that patients are currently on therapy or will be placed on therapy during the trial
