Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Patients With Adverse Events | 12 Weeks | The number of patients in each treatment group who reported at least 1 adverse event, including clinically significant changes from baseline in vital signs, 12-lead ECG, physical examinations and laboratory tests, from the time of the first dose until the last study visit. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Tmax of Apo805K1 Following Multiple Doses, Assessed at Day 14 | 12 hours | Tmax for dosages of 10 mg, 30 mg, 60 mg, or 100 mg Apo805K1, determined on Day 14. Serial blood samples for PK analysis were collected pre-dose and at 1, 2, 3, 4, 5, 6, 8, 10, and 12 hours post-dose. |
| AUC 0-infinity of Apo805K1 Following Multiple Doses, Assessed at Day 14 | 12 hours | AUC 0-infinity for dosages of 10 mg, 30 mg, 60 mg, or 100 mg Apo805K1, determined on Day 14. Serial blood samples for PK analysis were collected pre-dose and at 1, 2, 3, 4, 5, 6, 8, 10, and 12 hours post-dose. |
| T 1/2 of Apo805K1 Following Multiple Doses, Assessed at Day 14 | 12 hours | T 1/2 for dosages of 10 mg, 30 mg, 60 mg, or 100 mg Apo805K1, determined on Day 14. Serial blood samples for PK analysis were collected pre-dose and at 1, 2, 3, 4, 5, 6, 8, 10, and 12 hours post-dose. |
| Cmax of Apo805K1 Following Multiple Doses, Assessed at Day 14 | 12 hours | Cmax for dosages of 10 mg, 30 mg, 60 mg, or 100 mg Apo805K1, determined on Day 14. Serial blood samples for PK analysis were collected pre-dose and at 1, 2, 3, 4, 5, 6, 8, 10, and 12 hours post-dose. . |
| Efficacy of APO805K1 as Assessed by Achievement of PASI-75 | 12 weeks | The proportion of patients in each treatment group who achieved at least a 75% improvement in PASI score from baseline at Week 12 |
| Efficacy of Apo805K1 as Assessed by Change From Baseline at Week 12 in Lattice System-Physician Global Assessment (LS-PGA) Scores | Baseline to 12 weeks | The LS-PGA is a standardized method for determining categories of psoriasis severity. The percentage of body surface area involved is assessed on a scale ranging from 1 (0%) to 7 (51-100%); measures of plaque severity (thickness, erythema, and scaling) are assessed using a 4-point scale ranging from none to marked; and an algorithm is used to combine the above scores to determine a final score on a scale ranging from 0 (clear) to 7 (very severe). Thus, a decrease in LS-PGA score indicates improvement. This outcome measure compared the difference in change in LS-PGA score from baseline to Week 12 between the active treatment groups and the placebo group. |
| Efficacy of Apo805K1 as Assessed by Change From Baseline to Week 12 in Physician Global Assessment (PGA) Score | Baseline to 12 weeks | In the PGA, the physician assigns a single estimate of a patient's overall severity of the disease using a scale ranging from 0 (Clear) to 7 (Severe). (Unlike the LS-PGA, the individual elements of psoriasis plaque morphology or degree of body surface area involvement are not quantified.) Thus, a decrease in PGA score indicates improvement. This outcome measure compared the difference in change in PGA score from baseline to Week 12 between the active treatment groups and the placebo group. |
| Efficacy of Apo805K1 as Assessed by Change From Baseline in Psoriasis Area Severity Index (PASI) Scores | Baseline to 12 Weeks | PASI is a quantitative measure of psoriasis that combines an assessment of the severity of lesions and a measurement of how much of the body surface area is affected into a single score ranging from 0 (no disease) to 72 (maximal disease). Thus, a decrease in PASI score indicates improvement. This outcome measure compared the difference in change in PASI score from baseline to Week 12 between the active treatment groups and the placebo group. |
