    TKV was measured by centrally evaluated Magnetic Resonance Imaging (MRI).

    Time frame: Baseline and Month 25 (end of Initial Treatment Period Visit [ITPV])

Secondary outcomes

  1. Change From Baseline in Estimated Glomerular Filtration Rate (eGFR) at Months 12, 24, 25 and Early Termination

    eGFR was centrally evaluated. Glomerular filtration rate (GFR) is an index of kidney function that describes the flow of filtered fluid through the kidney. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was used to calculate eGFR. Month 25 is the end of the ITPV.

    Time frame: Baseline, Month 12, Month 24, Month 25 (end of ITPV), and early termination

  2. Time to First Occurrence or Worsening of Hypertension

    Time frame: Baseline up to Month 25 (end of ITPV)

  3. Time to First Occurrence or Worsening of Back and/or Flank Pain

    The time to first occurrence or worsening of back and/or flank pain was observed (defined as initial onset of polycystic kidney disease \[PKD\]-related chronic back and/or flank pain; initiation of pain medication treatment for PKD-related chronic back and/or flank pain; addition of a pain medicine for treatment of PKD-related chronic back and/or flank pain; increase in dose of pain medication for treatment of PKD-related chronic back and/or flank pain). The numbers presented correspond to the very first occurrence or worsening of back and/or flank pain in that treatment group.

    Time frame: Baseline up to Month 25 (end of ITPV)

  4. Time to First Occurrence of Gross Hematuria

    Gross hematuria is the presence of blood in the urine (defined as pink, red, or cola-colored urine due to the presence of red blood cells). The numbers presented correspond to the very first occurrence of gross hematuria in that treatment group.

    Time frame: Baseline up to Month 25 (end of ITPV)

  5. Time to First Occurrence of Proteinuria

    Time frame: Day 15 (pre-dose and 1, 2, 3, 4, 6, 8 and 24 hours post-dose)

  13. Apparent Oral Clearance (CL/F) of Bosutinib

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

    Time frame: Day 15 (pre-dose and 1, 2, 3, 4, 6, 8 and 24 hours post-dose)

  14. Apparent Volume of Distribution (Vz/F) of Bosutinib

    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

    Time frame: Day 1 (pre-dose and 1, 3, 5 and 24 hours post-dose), Day 15 (pre-dose and 1, 2, 3, 4, 6, 8 and 24 hours post-dose)

  15. Terminal Elimination Half-Life (t1/2) of Bosutinib

    t1/2 is the time measured for the plasma concentration to decrease by one half.

    Time frame: Day 1 (pre-dose and 1, 3, 5 and 24 hours post-dose), Day 15 (pre-dose and 1, 2, 3, 4, 6, 8 and 24 hours post-dose)

  16. Observed Accumulation Ratio (Rac) of Bosutinib

    Observed accumulation ratio (Rac) was calculated as AUC from time 0 to 24 hours (Day 15) divided by AUC from time 0 to 24 hours (Day 1).

    Time frame: Day 15 (pre-dose and 1, 2, 3, 4, 6, 8 and 24 hours post-dose)

  17. Change From Baseline in Kidney Disease Quality of Life (KDQoL)-36 Scale Scores at Month 25

    The KDQoL-36 is a 36-item questionnaire on kidney disease-specific measure of patient-reported quality of life with 5 subscales: physical and mental functioning (items 1-12); burden of kidney disease subscale (items 13-16); symptoms and problems (items 17-28); effects of kidney disease on daily life subscale (items 29-36). The raw scores are transformed linearly to a range of 0 to 100, with higher scores indicating better quality of life.

    Time frame: Baseline and end of ITPV (Month 25)

Other outcomes

SecondaryChange From Baseline in Kidney Disease Quality of Life (KDQoL)-36 Scale Scores at Month 25

The KDQoL-36 is a 36-item questionnaire on kidney disease-specific measure of patient-reported quality of life with 5 subscales: physical and mental functioning (items 1-12); burden of kidney disease subscale (items 13-16); symptoms and problems (items 17-28); effects of kidney disease on daily life subscale (items 29-36). The raw scores are transformed linearly to a range of 0 to 100, with higher scores indicating better quality of life.
