Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Participant is a healthy male or female between the ages of 18 and 55 years, inclusive, at Screening.
• Participant has a body mass index between 18 and 30 kg/m\^2, inclusive, at Screening.
• Participant is medically healthy, with no clinically significant medical history, physical examination, laboratory profiles, vital signs, or 12-lead ECG results at Screening, as deemed by the Principal Investigator (PI) or designee.
• If female of childbearing potential (including those with an onset of menopause \< 2 years prior to Screening, non-therapy-induced amenorrhea for \< 12 months prior to Screening or not surgically sterile \[absence of ovaries and/or uterus\]) must have a negative serum pregnancy test at Screening and Check-in and negative urine pregnancy tests at all protocol-specified time points (ie, prior to the teprotumumab dose and throughout participation in the Follow-up Period); female participants of childbearing potential who are sexually active with a non-vasectomized male partner must agree to use 2 reliable forms of contraception during the trial, 1 of which is recommended to be hormonal, such as an oral contraceptive. Hormonal contraception must be started at least 1 full cycle prior to Day 1 and continue for 180 days after receiving the dose of teprotumumab. Highly effective contraceptive methods (with a failure rate \< 1% per year), when used consistently and correctly, include implants, injectables, combined oral contraceptives, some intrauterine devices, vasectomized partner, or sexual abstinence. Abstinence should only be used as a contraceptive method if it is in line with the participant usual and preferred lifestyle. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) is not an acceptable method of contraception.
• If female, participant must agree not to donate an egg/oocyte from Day 1 until 180 days after receiving the dose of teprotumumab.
• If male, participant must be surgically sterile for at least 6 months prior to dosing or, if sexually active with a female partner of childbearing potential, must agree to use a barrier contraceptive method from Screening through 180 days after receiving the dose of teprotumumab.
• If male, must agree not to donate sperm from Day 1 until 180 days after receiving the dose of teprotumumab.
• Participant has adequate venous access.
• Participant understands the trial procedures in the ICF and is willing and able to comply with the prescribed treatment protocol and evaluations for the duration of the trial.
• First generation Japanese healthy male or female participants must meet all of the following as confirmed by interview:
• Descendants of 4 ethnic Japanese grandparents who were born in Japan
• Both parents are ethnic Japanese who were born in Japan
• Hold a Japanese passport or identity papers
• Have lived outside Japan for less than 10 years at the time of screening and lifestyle including diet has not changed significantly since leaving Japan.

You may not qualify if:

• Participant has a history or presence of a clinically significant medical or psychiatric condition or disease, in the opinion of the PI or designee.
• Participant has a history of any illness that, in the opinion of the PI or designee, might confound the results of the trial or pose an additional risk to the participant due to participation in the trial.
• Participant has a history or presence of alcoholism (defined as \> 10 standard drinks per week, where 1 standard drink = 284 mL of full-strength \[4.9% alc/vol\] beer, 30 mL of 40% \[alc/vol\] spirit or a 100 mL glass of wine\]) or drug abuse within the 6 months prior to Day 1 dosing.
• Participant has a history or presence of hypersensitivity or idiosyncratic reaction to components of teprotumumab or prior hypersensitivity reactions to a monoclonal antibody or history.
• Participant has a history or presence of:
• thyroid eye disease
• diagnosis of autoimmune diseases
• inflammatory bowel disease
• Participant has an alanine transaminase or aspartate transaminase level \> 1.5 times upper limit of normal at Screening or Check-in.
• Participant has glycated hemoglobin ≥ 6.5% and/or fasting glucose level (after at least an 8-hour fast) \> 126 mg/dL at Screening.
• Participant has clinically significant abnormal ECG measurements at Screening or prior to teprotumumab dosing, in the opinion of the PI, or has second- or third-degree atrioventricular block or any of the following:
• QRS \> 120 msec
• QTcF) \> 450 msec (males) or \> 470 msec (females)
• PR interval \> 220 msec
• Participant has a medical condition associated with increased risk of bleeding, including history of hematological diseases such as acquired platelet disorders and coagulation disorders, including drug-induced thrombocytopenia, idiopathic thrombocytopenia or von t medication.

Data Sharing

• IPD Sharing: Will share
• Shared Documents: STUDY PROTOCOL, SAP, ICF, CSR
• 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 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. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. 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.
