Arm && Interventions

Group	Intervention	Description
Allocetra-OTS	Allocetra-OTS	Single IA dose of Allocetra-OTS cells in suspension

Primary Outcome Measures

Name	Time	Method
Treatment-emergent adverse events and Serious adverse events following Allocetra-OTS injection	6 months	The safety and tolerability endpoint evaluates the incidence and severity of complications following intraarticular injection of Allocetra-OTS: * Injection-related reactions occurring during Allocetra-OTS injection, including injection interruption/discontinuation.; * Treatment-emergent adverse events following Allocetra-OTS injection.; * Treatment-emergent serious adverse events.; * Adverse events or serious adverse events related to the use of Allocetra-OTS as an intraarticular injection material.; * Safety assessments beyond 1 month following injection will focus on events that are at least possibly related to Allocetra-OTS treatment.

Secondary Outcome Measures

Name	Time	Method
SF-36 questionnaire response change along study period	6 month	SF-36 questionnaire response change along study period (questionnaires aimed at assessing quality of life,).
Efficacy of Allocetra-OTS- Pain mitigation as measured by Visual Analog Scale tool.	6 months	To assess the efficacy of Allocetra-OTS. Secondary endpoints for efficacy will be measured in terms of: • Pain mitigation as measured by VAS (Visual Analog Scale) tool in a range of 0-10 points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be').
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) response change along study period	6 month	Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) response change along study period (questionnaires aimed at assessing arthritis related function ).; The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4).; The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. Usually a sum of the scores for all three subscales gives a total WOMAC score, however there are other methods that have been used to combine scores.; Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.
