Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Participant was previously enrolled in Study 20062004.
  • Participant or participant's legally acceptable representative has provided /assent prior to initiation of any study-specific activities/procedures.

Exclusion criteria

Exclusion Criteria:

  • Participant likely to not be available to complete all protocol-required study visits or procedures, and/or to comply with all required study procedures to the best of the participant and investigator's knowledge.
  • Females of on denosumab and not willing to continue to use 1 highly effective method of during treatment and for 5 months after the end of treatment
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Study arms

  • Experimental
    Denosumab

    Participants who are still being treated with denosumab when 20062004 completes: 120 mg administered subcutaneously (SC) every 4 weeks (Q4W). For participants undergoing retreatment with denosumab: 120 mg administered SC on Days 1, 8, 15 and 28 then every 4 weeks subsequently.

    Drug: Denosumab

  • No intervention
    Safety Follow-up

    Participants who completed denosumab treatment and were in safety follow-up at the conclusion of 20062004 will have follow-up visits performed every 6 months via telephone or in-person clinic visit.

Interventions

  • 120 mg administered subcutaneously (SC) every 4 weeks (Q4W).

What researchers measure

Primary outcomes

  1. Number of Participants Experiencing Adverse Events (AEs) of Interest (EOI)

    EOIs assessed in the study were signs and symptoms of osteonecrosis of the jaw (ONJ), malignancy (including malignancy in GCTB), atypical femoral fracture (AFF), hypocalcemia, hypercalcemia after treatment discontinuation, pregnancy and lactation (if occurring during treatment or within 5 months of the last dose of denosumab). Hypocalcemia includes events that occurred after 30 days following the last dose of IP and includes TEAEs only. Other EOIs encompass all events from signing the informed consent to the end of the study (approximately 5 years). ONJ and AFF events were adjudicated by independent reviewers.

    Time frame: Up to approximately 5 years

Secondary outcomes

  1. Number of Participants Experiencing Treatment-emergent Adverse Events (TEAE)

    An AE is any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. An AE is considered as treatment-emergent if the AE occurs during the time period from the first dose of IP in this study through last dose of IP plus 30 days. TEAEs related to IP include only TEAEs for which the Investigator indicated there was a reasonable possibility they may have been caused by IP. AEs were graded (grade 3 \[severe or medically significant but not immediately life-threatening\], 4 \[life-threatening\], and 5 \[death related to the AE\]) using the Common Terminology Criteria for Adverse Events (CTCAE).

    Time frame: Up to approximately 5 years

  2. Number of Participants With Disease Progression or Recurrence of GCTB

    Disease progression or recurrence is defined as the best post-baseline response of progressive disease (PD) without any post-baseline complete response (CR) /partial response (PR) /stable disease (SD) or a post-baseline response of PD following a post-baseline CR/PR/SD. PD is defined as the response of progressive disease, locally recurrent disease or distant recurrence. CR is defined as no evidence of disease following surgical resection while on study 20062004. PR is defined as no new lesion or disease progression while enrolled in study 20062004. SD is defined as local disease progression/recurrence or distant metastatic disease while on study 20062004.

    Time frame: Up to approximately 5 years

  3. Number of Participants Receiving GCTB Interventions

    GCTB interventions include: surgery, chemotherapy, embolization, interferon, and radiotherapy.

    Time frame: Up to approximately 5 years

Individual participant data

Plan to share: Yes — De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.

Supporting information: Study protocol, Statistical analysis plan, Informed consent form, Clinical study report

Time frame: Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication (or other new use) have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

Access criteria: Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors, and if not approved, may be further arbitrated by a Data Sharing Independent Review Panel. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 20, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
