- Uncontrolled hypertension defined as sitting systolic blood pressure (SBP) \> 180 mmHg or diastolic blood pressure (DBP) \> 110 mmHg
- Subject has taken a cholesterylester transfer protein (CETP) inhibitor in the 12 months prior to randomization
- Subject has taken in the 6 weeks prior to LDL-C screening: red yeast rice, \> 200 mg/day niacin, \> 1000 mg/day omega-3 fatty acids (eg, dihydroxyacetone docosahexaenoic acid and eicosapentaenoic acid), stanols or prescription lipid-regulating drugs (eg, bile-acid sequestering resins, fibrates and derivatives) or other cholesterol lowering drugs or lipid-lowering dietary supplements or food additives other than statins and ezetimibe
- Treatment 3 months prior to LDL-C screening with any of the following drugs: systemic cyclosporine, systemic steroids, (intravenous \[IV\], intramuscular \[IM\], or by-mouth \[PO\]) (Note: hormone replacement therapy is permitted), vitamin A derivatives and retinol derivatives for the treatment of dermatologic conditions (eg, Accutane) (Note: vitamin A in a multivitamin preparation is permitted)

- Malignancy (except non-melanoma skin cancers, cervical in-situ carcinoma, breast ductal carcinoma in situ, or stage 1 prostate carcinoma) within the last 5 years prior to randomization
- Subject has previously received evolocumab or any other therapy to inhibit PCSK9
- Subject has known sensitivity to any of the active substances or their excipients to be administered during dosing, eg, carboxymethylcellulose
- 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.
- History or evidence of any other clinically significant disorder, condition or disease (with the exception of those outlined above) 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.
- Currently receiving treatment in another investigational device or drug study, or less than 30 days before randomization since ending treatment on another investigational device or drug study(s) or planning to receive other investigational procedures while participating in this study
- Female subject of childbearing potential not willing to use an acceptable method(s) of effective birth control during treatment with investigational product and for an additional 15 weeks after the end of treatment with investigational product. Female subjects of non-childbearing potential who are not required to use contraception during the study and include those who have had a:
- hysterectomy
- bilateral salpingectomy
- bilateral oophorectomy or
- who are postmenopausal i. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. \[A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy (HRT). However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.
- ii. Females on HRT and whose menopausal status is in doubt will be required to use one of the non-hormonal highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment.
- Acceptable methods of effective birth control include:
- sexual abstinence (defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments; the reliability of sexual abstinence must be evaluated in relation to the duration of the trial and the preferred and usual lifestyle of the subject. \[Periodic abstinence (eg., calendar, ovulation, symptothermal, postovulation methods), declaration of abstinence for the duration of a study, and withdrawal are not acceptable methods of contraception\])
- bilateral tubal ligation/occlusion
- vasectomized partner (provided that partner is the sole sexual partner of the female subject of childbearing potential and that the vasectomized partner has received medical assessment of the surgical success)
- use of hormonal birth control methods (oral, intravaginal (eg. vaginal ring(s), transdermal, injectable, or implantable)
- intrauterine devices (IUDs)
- intrauterine hormonal releasing system (IUS)
- 2 barrier methods (each partner must use 1 barrier method) the male uses a condom and the female must choose either a diaphragm, OR cervical cap, OR contraceptive sponge with spermicide. If spermicide is not commercially available in the country or region, the 2 barrier method without spermicide is acceptable. (A female condom is not an option due to the risk of tearing when both partners use a condom.)
- Female subject is pregnant or breast feeding (nursing), planning to become pregnant or planning to breastfeed (nurse) during treatment with investigational product and/or within 15 weeks after the end of treatment with investigational product.
