E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
In part B of the study regular MRI assessments will be conducted on a sub-population of patients, who agree to undergo such assessments. MRIs will be read centrally. MRI changes (in subset of patients in Part B only) from baseline to Day 7 and Week 12 will be evaluated and summarised descriptively. |

E.3 | Principal inclusion criteria |
• Signed and dated Informed Consent. • Male or female. • >= 40 years of age. • Body mass index < 30. • Negative pregnancy test for females of child bearing potential (pre-menopausal, < 2 years post-menopausal, not surgically sterile). Female patients of childbearing potential and their partners must to use 2 forms of contraception (including 1 barrier method), from screening until 2 months after the injection with ESBA105. Primary forms of contraception include intrauterine devices, oral contraceptive agents that the patient has already been using for at least 90 days before screening, and injectable/implantable/insertable hormonal birth control products. Secondary forms of contraception include diaphragms, latex condoms, and cervical caps. • Patients with diagnosed OA of the knee (unilateral or bilateral) according to the American College of Rheumatology (ACR) Criteria for classification of idiopathic OA (clinical and radiological criteria) of the knee at Screening (for ACR criteria, see Appendix 16.1). • Radiographic evidence of tibiofemoral OA within the last 6 months before Screening, consisting of Grade II or Grade III changes, according to Kellgren Lawrence grading system. • Presence of pain in the index knee (in case of bilateral OA, “index knee” is the more painful knee) defined by a level of >= 60 mm on a 100 mm (linear) VAS at Screening. • Paracetamol and NSAIDs (apart from acetyl salicylic acid ≤ 100 mg/day) must be withdrawn at least 24 hours prior to Screening (Day -7 [-3 days]). • Paracetamol, which is allowed to be re-initiated after completion of Screening assessments (Day -7 [-3 days]), must be withdrawn again as of Day -3. • Doses of “chondroprotective” agents containing glucosamine and/or chondroitin sulphate must be stable for at least 3 months prior to Screening. • Doses of any non-prescription medication claiming effects on signs or symptoms of OA (e.g., Rosa canina (lithocin), Perna canaliculus (“Grünlippenmuschelextrakt”), Harpagophytum procumbens (“Teufelskralle”)) must be stable for at least 3 months prior to Screening. • Use of non-pharmacological treatment modalities (e.g., physical therapy, biomechanical devices, magnetic therapy, ointments, and heating pads) must be stable for at least 3 months prior to Screening. • Negative QuantiFERON-TB Gold test. • Ability to comply with the study requirements

Additional criteria for the sub-population of patients undergoing MRI (Part B only): • Contraindications to MRI. • Known allergy to gadolinium contrast material. • Presence of chronic renal failure defined by a calculated creatinine clearance (CrCl) of < 60 mL/min, using the Cockcroft-Gault estimate for GFR as follows: CrCl=(140-age (years)) x weight (kg))/(serum creatinine (mg/dL) x 72), with female gender adjustment (CrCl female = CrCl x 0.85). |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary efficacy endpoint is the change from Baseline (Day 0) to Day 7 in Visual Analogue Scale (VAS) to assess the intensity of knee pain. The VAS pain intensity score will be determined by measuring the change in millimetres on a 100 mm scale, as indicated by the patient marks. |
