Official title: DCA114273: A Study Comparing Denosumab with Zoledronic Acid in Subjects of Asian Ancestry with Bone Metastases from Solid Tumors
Trial description: This is a randomized, double-blind, double-dummy study designed to provide bridging data in an Asian population to Amgen’s studies of denosumab in subjects with bone metastases from solid tumors. The study is designed to provide data to a large global dataset of phase-III studies including breast cancer, prostate cancer, and all solid tumors, plus multiple myeloma, to support the regulatory approval for marketing and patient access to denosumab for the prevention of SREs in Chinese subjects with bone metastases from solid tumors. The primary objective of this study is to evaluate and compare the percent change from baseline to Week 13 in the bone marker urinary amino-terminal cross-linking telopeptide of type I collagen (uNTx) corrected for urine creatinine (uNTx/uCr) in subjects treated with denosumab to those treated with zoledronic acid. The study is designed to test the superiority of denosumab over zoledronic acid.

- Subject understands the nature and purpose of this study and the study procedures, which have been explained by the Investigator or delegate, and subject has signed the written informed consent for the overall study. The subject must sign a separate written informed consent to be eligible for enrolment in the pharmacokinetic substudy.
- Adult (aged >=18 years) of Asian ancestry with a histologically or cytologically confirmed solid tumor. In addition, subjects who are enrolled at a center in mainland China or at an SFDA-certified center in Hong Kong including the approximately 33 subjects in the pharmacokinetic substudy must be of Chinese race, ancestry, or heritage. Subjects enrolled in other regions or countries, such as Taiwan and Singapore, or at a non-SFDA-certified center in Hong Kong, are not required to be of Chinese race or ancestry.
- Any serious and/or unstable pre-existing medical, psychiatric disorder, or other conditions that, in the opinion of the Investigator, could interfere with subject’s safety, obtaining informed consent or compliance to the study procedures; The Investigator should consult the GSK Medical Monitor prior to enrolling a subject if s/he is unsure if a condition might interfere with the subject’s safety or participation in this study.
- Any prior treatment with intravenous (IV) or oral bisphosphonates.
Inclusion and exclusion criteria
Inclusion criteria:
- Subject understands the nature and purpose of this study and the study procedures, which have been explained by the Investigator or delegate, and subject has signed the written informed consent for the overall study.
