Study of Emactuzumab for Tenosynovial Giant Cell Tumor (TGCT)

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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, subject to eligibility, to crossover 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:12 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:CHILD, ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Age \>12 years
  2. * Biopsy-confirmed (standard of care diagnosis history) local or diffuse TGCT where surgical resection would be associated with predicted worsening functional limitations through surgical joint damage, and/or subject has an anticipated high risk of early recurrence as determined by a multidisciplinary tumour board or equivalent, or any other morbidity associated with the surgery, and/or surgical treatment is not expected to improve the clinical outcomes of the subject.
  3. * Measurable disease: longest diameter ≥20 mm.
  4. * Adequate organ and bone marrow function
  5. * If a woman of childbearing potential (WOCBP), must have a negative pregnancy test prior to starting treatment and agree to use a highly effective method of contraception
  6. * Participants must have given written consent
  1. * If a female, the subject is pregnant or breast feeding.
  2. * Medical conditions, including auto-immune, requiring systemic immunosuppression. Any systemic treatment for these conditions (eg, glucocorticoids) is not allowed within 4 weeks of Screening and during the study.
  3. * Known metastatic TGCT or other active cancer that requires concurrent or planned treatment
  4. * Received systemic therapy for TGCT (investigational or approved) targeting CSF-1 or CSF-1R or any multi-tyrosine kinase inhibitor (eg nilotinib and imatinib) within 3 months prior to screening
  5. * Any surgery, chemotherapy or radiotherapy within 3 months of screening
  6. * Unresolved clinically significant toxicity from a previous treatment or any history of serious liver toxicity.
  7. * Current or chronic history of liver disease.
  8. * Inadequate renal and liver function
  9. * Systemic antiretroviral therapy within 3 months of baseline
  10. * Within 6 months of baseline has experienced: clinically significant myocardial infarction, severe/unstable angina pectoris, congestive heart failure New York Heart Association (NYHA) Class III or IV, or pulmonary disease (NYHA Criteria 1994) including severe thromboembolic event; incompletely healed clinically significant wounds, including bone fractures; pathological fracture or significant hypercalcaemia.
