Group 1: Subjects receiving emactuzumab administered on Day(D)1 and repeated once every two weeks (Q2W) for a total of 5 times, followed by an observation period of 3 months leading to a total period of 24 weeks in Part 1 and continued with a follow-up phase in Part 2. Subjects assigned to active drug in Part 1 have the option to receive open-label retreatment under certain circumstances

Group 2: Subjects receiving placebo administered as iv infusion on D1 and repeated once every two weeks (Q2W) for 5 times followed by an observation period of 3 months to a total period of 24 weeks in Part 1 will have the option to crossover under certain circumstances to open-label emactuzumab once every 2 weeks (Q2W) for a total of 5 times in Part 2.

This is a multicenter, Phase 3, randomised, double-blind, placebo-controlled study, which aims to evaluate the efficacy and safety of the investigational drug emactuzumab for the treatment of patients with localized or diffuse TGCT where surgical removal of the tumor is not viewed as an option.

The study consists of two parts. In Part 1, eligible subjects will be assigned in a 2:1 ratio to receive either emactuzumab or matching placebo in a double-blind fashion, that will be administered in total 5 times as an intravenous (i.v.) infusion once every 2 weeks. This will be followed by an observation period of 3 months leading to a total duration of 24 weeks in Part 1. A number of assessments will be carried out during the course of the study, including physical examinations, blood tests, imaging studies, electrocardiograms, and questionnaires. Part 2 is a long-term double-blind follow-up phase of the subjects on emactuzumab or placebo. Subjects assigned to placebo in Part 1 have the option to crossover under certain circumstances to receive open-label emactuzumab in Part 2. Subjects assigned to active drug in Part 1 have the option to receive open-label retreatment under certain circumstances.

Villo-nodular synovitis can affect the joints, bursae or tendon sheaths. This condition is rare, with 1.8 cases per million inhabitants. The hip is affected in 3.6 to 18.1% of cases. The age of predilection is between 30 and 50 years old and this condition is rarely described in children.

Two articles report a case of villous-nodular synovitis of the child's hip. Surgical treatment by resection seems to be consensus but various adjuvant treatments are also proposed. A case of villous-nodular synovitis of the hip in children was treated without surgical intervention. The main objective of this study was to evaluate the efficacy of surgical treatment of villous nodular synovitis of the hip in children.

Part 1: Open-label, sequential PLX73086 dose escalation in approximately 36 solid tumors subjects.

Part 2: Extension cohort at the recommended phase 2 dose (RP2D) of PLX73086 in approximately 30 subjects with histologically confirmed, unresectable, locally advanced or refractory TGCT (including metastatic disease).

PLX73086

The purpose of this research study is to evaluate safety, pharmacokinetics and preliminary efficacy of the investigational drug PLX73086 in subjects with solid tumors including subjects with locally advanced or refractory tenosynovial giant cell tumor (TGCT).
