| PDA001 | Biological | Dose escalation study: Subjects will be assigned to 1 of 2 treatment groups (1 unit or 4 units vs. vehicle control) based on the order in which they enroll in the study. Intravenous infusion will be administered on days 0 and 7. Nonresponders will be unblinded after 12 weeks of study. Non- responders on vehicle control will be re-dosed with the active PDA001 dose assigned at baseline (2 infusions, 7 days apart). Nonresponders taking active PDA001 will enter the safety follow-up portion of the study. Responders at 12 weeks will continue in the safety and efficacy follow-up portion of the study until 12 months of study. Responders will be treated for RA flare between 3-9 months of study with the active PDA001 dose assigned at baseline (2 infusions, 7 days apart). |

| Number/percent of subjects achieving a clinical response based on their Clinical Disease Activity Index (CDAI) at each scheduled visit during the first 12 months following the first infusion of study drug. | A subject is considered a responder based on the Clinical Disease Activity Index (CDAI): A composite index where CDAI = SJC+TJC+SGA+PGA. SJC and TJC are the numbers of swollen and tender joints based on 28-joint counts; SGA and PGA represent the subject's and physician's global assessment of disease activity. The CDAI score ranges from 0-76. Clinical disease activity is defined according to CDAI scores where Remission is ≤ 2.8, Low Disease Activity > 2.8 and ≤ 10, Moderate Disease Activity > 10 and ≤ 22, and High Disease Activity > 22 | Baseline and each scheduled visit through 12 months following the first infusion of study drug |
| Number/percent of subjects achieving a clinical response based on their Disease Activity Score (DAS 28) score at each scheduled visit during the first 12 months following the first infusion of study drug | A subject is considered a responder based on Disease Activity Score 28 (DAS 28): A measure of severity of disease derived from the following: 28 tender joint count (TJC28); 28 swollen joint count (SJC28), which do not include the distal interphalangeal (DIP) joints, the hip joint, or the joints below the knee, CRP, and SGA. A DAS 28 score > 5.1 indicates high disease activity, a DAS28 score < 3.2 indicates low disease activity, and a DAS28 score < 2.6 indicates clinical remission | Baseline and each scheduled visit through 12 months following the first infusion of study drug |
| Number/Percent of Participants Who Achieve the European League Against Rheumatism (EULAR) Response Criteria Using CRP at Month 12 | A subject is considered a responder based on EULAR response: The EULAR response criteria classify each subject as a good, moderate or non-responder to treatment based on the degree of improvement from baseline and the level of disease activity at the endpoint. EULAR response is derived using the individual subject's DAS28 as the measure of severity of disease. Good or moderate response is defined as follows: Good response: DAS28 at the time point ≤ 3.2 and improvement from baseline > 1.2 Moderate response: DAS28 at the time point > 3.2 and improvement from baseline > 1.2, or DAS28 at the time point ≤ 5.1 and improvement from baseline > 0.6 and ≤ 1.2 | Baseline and each scheduled visit through 12 months following the first infusion of study drug. |
| The change from baseline in the ACR core components. ACR Core Component #1: Percentage Change From Baseline in the Swollen Joint Count at each scheduled visit. | Joint tenderness is the presence of pain in a joint when pressure is applied by the examiner to elicit tenderness. The 68 tender joint count evaluates the following joints: upper-temporomandibular, sternoclavicular, acromioclavicular, shoulder, elbow, wrist, meta-carpophalangeal, proximal interphalangeal and distal interphalangeal; lower: hip, knee, ankle, midtarsal, metatarsophalangeal and proximal interphalangeal. | Baseline and each scheduled visit through 12 months following the first infusion of study drug |
| ACR Core Component #2: Percentage Change From Baseline in the Swollen Joint Count at each scheduled visit through Month 12 following the initial infusion of study drug | Joint swelling is soft tissue swelling that is detectable along the joint margins and is assessed by inspection and direct palpation of the joint, by the examiner. The ACR 66 swollen joint count evaluates the following joints: upper-temporomandibular, sternoclavicular, acromioclavicular, shoulder, elbow, wrist, metacarpophalangeal, proximal interphalangeal and distal interphalangeal; lower: knee, ankle, midtarsal, metatarsophalangeal and proximal interphalangeal. | Baseline and at each scheduled visit through Month 12 following the initial infusion of study drug |
| ACR Core Component #3 Percentage Change From Baseline in the Subject Assessment of Pain at each scheduled visit through Month 12 following the initial dose of study drug | The Subject Assessment of Pain was measured asking the participant to place a vertical line on a 100-mm visual analog scale on which the left-hand boundary (score = 0 mm) represents "no pain," and the right-hand boundary (score = 100 mm) represents "pain as severe as can be imagined." The distance from the mark to the left-hand boundary was recorded in millimeters. | Baseline and at each scheduled visit through Month 12 following the initial dose of study drug |
| ACR component #4 Percentage Change From Baseline in the Subject Global Assessment of Disease Activity at each scheduled visit through Month 12 following the initial dose of study drug | The Subject Global Assessment of Disease Activity was measured asking the participant to place a vertical line on a 100-mm visual analog scale on which the left-hand boundary (score = 0 mm) represents " lowest disease activity," and the right-hand boundary (score = 100 mm) represents " highest disease activity." The distance from the mark to the left-hand boundary was recorded in millimeters. | Baseline and at each scheduled visit through Month 12 following the initial dose of study drug |
| ACR Component #5 Percentage Change From Baseline in the Physician Global Assessment of Disease Activity at each scheduled visit through Month 12 following the initial dose of study drug | The Physician Global Assessment of Disease Activity was measured asking the physician to assess the subject's current arthritis disease activity by placing a vertical line on a 100-mm visual analog scale on which the left-hand boundary (score = 0 mm) represents " lowest disease activity," and the right-hand boundary (score = 100 mm) represents " highest disease activity." The distance from the mark to the left-hand boundary was recorded in millimeters | Baseline and Month 12 |
| ACR Component #6; Percentage Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at each scheduled visit through Month 12 following the initial dose of study drug | The Health Assessment Questionnaire - Disability Index (HAQ-DI) was a patient-reported questionnaire consisting of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and usual activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from baseline in the overall score indicate improvement in functional ability. | Baseline and at each scheduled visit through Month 12 following the initial dose of study drug |
| ACR Component#7 Percentage Change From Baseline in the High Sensitivity C-Reactive Protein (CRP) at each scheduled visit through Month 12 following the initial dose of study drug | C-Reactive Protein (CRP) is a substance produced by the liver that increases in the presence of inflammation in the body. An elevated CRP level is identified with blood tests and is considered a non-specific "marker" for disease | Baseline at each scheduled visit through Month 12 following the initial dose of study drug |
| ACR Component #8 Percentage Change From Baseline in Erythrocyte Sedimentation Rate (ESR) at each scheduled visit through Month 12 following the initial dose of study drug | The erythrocyte sedimentation rate (ESR) is a blood test that can reveal inflammatory activity. The subject's blood is placed in a tall, thin tube, red erythrocytes gradually settle to the bottom. Inflammation can cause the cells to clump together. Because these clumps of cells are denser than individual cells, they settle to the bottom more quickly. The ESR test measures the distance red blood cells fall in a test tube in one hour. The farther the red blood cells have descended, the greater the inflammatory response | Baseline and at each scheduled visit through Month 12 following the initial dose of study drug |
| Change from baseline in rheumatoid factors at each scheduled visit through Month 12 following the initial dose of study drug | Rheumatoid factor is an antibody that is measurable in the blood. Rheumatoid factor is actually an antibody that can bind to other antibodies. High levels of rheumatoid factor can indicate a tendency toward more aggressive disease and/or a tendency to develop rheumatoid nodules and rheumatoid lung disease. | Baseline and each scheduled visit through Month 12 following the initial dose of study drug |
| Time to flare of Rheumatoid Arthritis (RA) symptoms | A flare is defined as a 20% increase in both tender and swollen joint counts, an increase in Physician Global Assessment of Disease ≥ 20 mm and an increase in at least 1 of 2 criteria (Patient Global Assessment of Disease ≥ 20 mm, Patient Assessment of Pain ≥ 20 mm) when compared with corresponding values from the subject's best response. Best response is determined by the subject's lowest CDAI score | At defined intervals |
| Changes in inflammatory markers including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum amyloid A (SAA), and IL-6 | Inflammatory markers are certain laboratory tests performed using the subjects' serum that indicate the presence of RA. Changes in these test results may indicate an improvement in RA | At defined intervals |
| Change From Baseline in the Disease Activity Score 28 (DAS 28) Using CRP | The DAS28 measures the severity of disease at a specific time and is derived from the following variables: • 28 tender joint count (TJC28) • 28 swollen joint count (SJC28), which do not include the distal interphalangeal (DIP) joints, the hip joint, or the joints below the knee; • C-reactive protein (CRP) • Subject's global assessment of disease activity (SGA). A DAS28 score higher than 5.1 indicates high disease activity, a DAS28 score less than 3.2 indicates low disease activity, and a DAS28 score less than 2.6 indicates clinical remission. Remission: ≤ 2.8; Low Disease Activity: > 2.8 and ≤ 10; Moderate Disease Activity: > 10 and ≤ 22; High Disease Activity: > 22 | Baseline and Month 6 |
| Change From Baseline in the Clinical Disease Activity Index (CDAI) at Month 3 | Clinical Disease Activity Index (CDAI): A simplified composite index as defined by: CDAI = SJC + TJC + SGA + PGA) • SJC and TJC are the numbers of swollen and tender joints based on 28-joint counts. • SGA and PGA represent the subject's and physician's global assessment of disease activity. o The CDAI score ranges from 0-76. Clinical disease activity is categorized according to CDAI scores where Remission ≤ 2.8, Low Disease Activity > 2.8 and ≤ 10, Moderate Disease Activity > 10 and ≤ 22, and High Disease Activity > 22 | Baseline and Month 3 |
| Change From Baseline in the Clinical Disease Activity Index (CDAI) at Month 6 | Clinical Disease Activity Index (CDAI): A simplified composite index as defined by: CDAI = SJC + TJC + SGA + PGA) • SJC and TJC are the numbers of swollen and tender joints based on 28-joint counts. • SGA and PGA represent the subject's and physician's global assessment of disease activity. o The CDAI score ranges from 0-76. Clinical disease activity is categorized according to CDAI scores where Remission ≤ 2.8, Low Disease Activity > 2.8 and ≤ 10, Moderate Disease Activity > 10 and ≤ 22, and High Disease Activity > 22 | Baseline and Month 6 |
