简要总结
This is a phase 1b, open-label, single dose study in healthy male subjects. Approximately 12 healthy male subjects will receive a subcutaneous injection of denosumab on Day 1. Subjects will be followed by a 105 day treatment-free follow-up period.

入选标准
- •Subject has provided informed consent; Healthy male between ≥40 to ≤ 65 years of age (inclusive) at the time of enrollment; Subject must be willing and able to produce a semen sample on seven separate study visits; Subject must be willing to refrain from ejaculation for a 48 hour period prior to each sample collection;
排除标准
- •Any condition or drug therapy that might interfere with the subjects ability to ejaculate and produce a semen sample; Clinically significant abnormality during the screening physical examination, ECG, or laboratory evaluation; Known history of blood in urine or semen; Osteonecrosis of the jaw (ONJ) or risk factors for ONJ such as invasive dental procedures (eg, tooth extraction, dental implants, oral surgery in the past 6 months), poor oral hygiene, periodontal and/or pre-existing dental disease; Recent tooth extraction (within 6 months of screening visit); Evidence of hypocalcemia at screening; Known vitamin D deficiency; Malignancy (except non-melanoma skin cancers) within the last 5 years; Positive for human immunodeficiency virus (HIV) at screening or known diagnosis of AIDS; Positive Hepatitis B Surface Antigen (HepBsAg) (indicative of chronic Hepatitis B) or detectable Hepatitis C virus Ribonucleic acid (RNA) by Polymerase Chain Reaction (PCR) at screening (indicative of active Hepatitis C - screening is generally done by Hepatitis C Antibody (HepCAb), followed by Hepatitis C virus RNA by PCR if HepCAb is positive); History of hypersensitivity or allergic reaction to mammalian cell derived drug products or sensitivity to any of the products or components to be administered during dosing; Known intolerance to calcium or vitamin D supplements; Subject previously has entered this study or has been previously exposed to denosumab in the past 12 months; Has donated or lost ≥ 400 mL of blood or plasma within 8 weeks prior to screening; Positive urine screen for alcohol and/or potential drugs of abuse at screening unless medication is prescribed by a physician and approved by the Investigator and Amgen; Known alcohol abuse or use of illicit drugs within 12 months of enrollment; Subject is unwilling or unable to limit alcohol consumption throughout the course of the study. Alcohol is prohibited 24 hours prior to screening and administration of investigational product. Alcohol is limited to no more than 2 drinks per day for the duration of the study; where a standard drink is equivalent to 12 ounces of regular beer, 8-9 ounces of malt liquor, 5 ounces of wine, or 1.5 ounces of 80 proof distilled spirits; Currently receiving treatment in another investigational device or drug study, or less than 30 days or 5 half-lives (whichever is longer) since ending treatment on another investigational device or drug study(s). Other investigational procedures while participating in this study are excluded; Use of any non-Amgen approved over-the-counter or prescription medications, within the 14 days or 5 half-lives (whichever is longer), prior to receiving the dose of denosumab. Acetaminophen (up to 2 g per day) for analgesia and hormone replacement therapy (eg, androgen, thyroid) will be allowed. Other medications may be approved following review by the Principal Investigator and the Amgen Medical Monitor. Written documentation of this review and Amgen acknowledgement is required for subject participation; Subject 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 subject and Investigator's knowledge; Subject has any kind of disorder that, in the opinion of the Investigator, may compromise the ability of the subject to give written informed consent and/or to comply with all required study procedures; History or evidence of any other clinically significant disorder, condition or disease that, in the opinion of the Investigator or Amgen physician, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion
