- Incidence of treatment-emergent adverse events (TEAEs) during the study [ Time Frame: From Entry Visit of PA0009 until Safety Follow-Up Visit (up to Week 120) ]An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
- Incidence of treatment-emergent serious adverse events (SAEs) during the study [ Time Frame: From Entry Visit of PA0009 until Safety Follow-Up Visit (up to Week 120) ]Once it is determined that a subject experienced an adverse event (AE), the seriousness of the AE must be determined. An SAE must meet 1 or more of the following criteria: death, life-threatening, significant or persistent disability/incapacity, congenital anomaly/birth defect, important medical event, initial inpatient hospitalization or prolongation of hospitalization.) product.
- Subjects who withdrew due to an treatment-emergent adverse event (TEAE) during the study [ Time Frame: From Entry Visit of PA0009 until Safety Follow-Up Visit (up to Week 120) ]An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
- ACR20 (American College of Rheumatology 20% Improvement) Response at Week 48 calculated relative to Baseline of PA0008 [ Time Frame: Baseline of PA0008, Week 48 ]The ACR20 response rate is based on a 20% or greater improvement of arthritis relative to Baseline of PA0008.
- ACR50 (American College of Rheumatology 50% Improvement) Response at Week 48 calculated relative to Baseline of PA0008 [ Time Frame: Baseline of PA0008, Week 48 ]The ACR50 response rate is based on a 50% or greater improvement of arthritis relative to Baseline of PA0008.
- ACR70 (American College of Rheumatology 70% Improvement) Response at Week 48 calculated relative to Baseline of PA0008 [ Time Frame: Baseline of PA0008, Week 48 ]The ACR70 response rate is based on a 70% or greater improvement of arthritis relative to Baseline of PA0008.
- Change from Baseline of PA0008 in Maastricht Ankylosing Spondylitis Enthesitis Index (MASES) at Week 48 calculated relative to Baseline of PA0008 [ Time Frame: Baseline of PA0008, Week 48 ]The MASES is an index that measures the severity (ie, intensity and extent) of enthesitis through the assessment of 13 entheses each scored as 0 or 1 and then summed for a possible score of 0 to 13.
- Change from Baseline of PA0008 in the Leeds Dactylitis Index (LDI) at Week 48 calculated relative to Baseline of PA0008 [ Time Frame: Baseline of PA0008, Week 48 ]Presence of dactylitis will be assessed using the LDI basic which evaluates for a >=10% difference in the circumference of the digit compared to the opposite digit this is then multiplied by the tenderness score, using a simple grading system (0=absent, 1=present).
- PASI75 (Psoriasis Area Severity Index) Response at Week 48 calculated relative to Baseline of PA0008 [ Time Frame: Baseline of PA0008, Week 48 ]
The PASI75 response is based on at least 75% improvement in the PASI score compared to Baseline in PA0008.
The Investigator assesses the average redness, thickness, and scaliness of lesions in each body area (each on a 5-point scale); 0=none, 1=slight, 2=moderate, 3=marked, and 4=very marked. The PASI score ranges from 0 to 72 with a higher score indicating increased disease severity.
- PASI90 (Psoriasis Area Severity Index) Response at Week 48 calculated relative to Baseline of PA0008 [ Time Frame: Baseline of PA0008, Week 48 ]
The PASI90 response is based on at least 90% improvement in the PASI score compared to Baseline in PA0008.
The Investigator assesses the average redness, thickness, and scaliness of lesions in each body area (each on a 5-point scale); 0=none, 1=slight, 2=moderate, 3=marked, and 4=very marked. The PASI score ranges from 0 to 72 with a higher score indicating increased disease severity.
