- •Subject who diagnosed knee osteoarthritis according to ACR criteria at screening visit, having pain in the knee and osteophyte formation in the X-ray, and one or more criteria as follows :
- •Aged >50
- •Morning stiffness < 30 minutes
- •Crepitus on knee motion
- •Prior to administration of IP, Subject with 50mm~70mm of 100mm Pain Visual Analog Scale (VAS) during activity of the knee of osteoarthritis(target lesion).
- •Subject with Grade 2 or Grade 3 on the knee osteoarthritis(target lesion) by Kellgren & Lawrence radiographic grading system
- •Subject who has pain on the knee osteoarthritis at least for 6 months before screening visit.
- •Subject who agrees not to use rescue medication within 48-hour of regular visit date.
- •Subject who agrees not to have ancillary physiotherapy
- •One-sided knee osteoarthritis subject or both-sided knee osteoarthritis subject who can designate the Target Lesion to one side, according to the follow criteria.
- •Designate the one with a higher 100 mm Pain Visual Analog Scale (VAS) than another, as the target lesion.
- •If 100 mm Pain Visual Analog Scale (VAS) is the same, designate the one with a higher Kellgren & Lawrence Grade than another, as the target lesion.
- •If both 100 mm Pain Visual Analog Scale (VAS) and Kellgren & Lawrence Grade are the same, designate the one that causes more clinical symptoms other than pain.
- •If above criteria are all the same, designate the right knee as the target lesion.
- •Subject who has voluntarily written informed consent for study participation.
Exclusion Criteria
- •Subject who has secondary knee osteoarthritis such as inflammatory or infectious joint disease or rheumatoid arthritis.
- •Subject who has surgical history(ex. knee replacement surgery) on the knee osteoarthritis lesion(target lesion).
- •Subject who has conditions that can affect the joints(gout, recurrent caustic gout, joint fracture, primary osteochondrosis, Paget's disease, ochronosis, acromegaly, hematochromatosis, Wilson's disease, genetic disease(ex: hyperkinesia) and collagen gene related disorders.
- •Subject whose BMI greater than or equal to 30kg/m2 at screening.
- •Subject who is applicable to the followings prior to first day of IP administration.
- •Intra-articular injected hyaluronic acid, cell therapy and gene therapy within 6 months prior to IP administration
- •Intra-articular injected steroids into the knee osteoarthritis lesion(target lesion) within 3 months prior to IP administration
- •Administered NSAIDs or glucosamine, chondroitin sulfate, oral steroid within 14 days prior to IP administration.
- •Administered analgesics within 1 days prior to IP administration
- •Subject who has a psychological disorder(alcohol or drug addiction) and is judged by the investigator to have problems with the safety of the subject or to cause confusion in the interpretation of clinical trial results
- •Subject who has osteoarthritis on the other sites not knee(ex. Hip joint) or has pain due to other disorder so that the investigator determined not suitable for participation of the clinical trial.
- •Subject who has uncontrolled type 1 or type 2 diabete mellitus at screening visit(Glycated Hemoglobin (HbA1c) > 8%)
- •Subject has a positive test result for HIV antibody or hepatitis B antigen, hepatitis C antibody.
- •Subject who has malignant tumor history within 5 year prior to screening visit.
- •Subject who is participated in other clinical trials within 30 days prior to screening.
- •As a result of screening examination(laboratory or ECG, vital sign), subject who has clinically significant findings that are not suitable for participation in the clinical trials.
- •Subject who is pregnant or breastfeeding
- •Subject who does not agree to use a medically acceptable method of contraception during clinical trial.
- •Besides, in case investigator determine that subject is unsuitable for study participation.
