Inclusion Criteria:~For All Aims:~1. Patient has provided informed consent.~2. Patient is 18 years of age or older.~3. Patient must be receiving maintenance hemodialysis for at least 3 months, with adequate hemodialysis with a delivered Kt/V 1.2 or urea reduction ratio (URR) 65% within 4 weeks prior to screening laboratory assessments.~4. Dialysate calcium concentration must be stable for at least 4 weeks prior to screening laboratory assessments.~5. Patient must have severe HPT as defined by two laboratory screening pre-dialysis serum PTH values \>9-times ULN for the PTH assay, measured on two consecutive monthly lab checks prior to entering the study.~6. The patient has an uncontrolled PTH defined by KDIGO as a PTH greater than 9 times the upper limit of normal of the assay (720 pg/mL for Rogosin):~   AND one of the following:~  * The patient has never been on cinacalcet OR,~  * The patient received daily cinacalcet for less than 3 months and has been off cinacalcet for at least 3 months prior to enrollment OR ,~  * The patient received daily cinacalcet for more than 3 months and has been off cinacalcet for at least 6 months prior to enrollment OR,~  * The patient received a modified dose of three times weekly cinacalcet and has been off cinacalcet for at least one month prior to enrollment.~7. Scheduled to receive etelcalcetide for the treatment of HPT per standard of care.~8. If receiving vitamin D sterols, patient must have had no more than a maximum dose change of 50% within the 4 weeks prior to screening laboratory assessments, remain stable through randomization, and be expected to maintain stable doses for the duration of the study, except for adjustments allowed per protocol\*.~9. Patient must have one screening pre-dialysis serum Ca laboratory value at least at the lower limit of normal for the assay measured within 4 weeks prior to entering the study.~10. A patient receiving calcium supplements must have had no more than a maximum dose change of 50% within 2 weeks prior to screening laboratory assessments and remain stable throughout the study, except for adjustments allowed per protocol\*.~11. A patient receiving phosphate binders must have had no more than a maximum dose change of 50% within the 2 weeks prior to screening laboratory assessments, remain stable through, and be expected to maintain stable dose for the duration of the study, except for adjustments allowed per protocol\*.~12. The treating physician considers the etelcalcetide dose and timing points described in this protocol as acceptable/optimal for their patient.~13. Female patients must be willing to use highly effective contraception during the study and for 3 months after the last dose of etelcalcetide (unless postmenopausal or surgically sterilized).~For Aim 1:~1. Total alkaline phosphatase ≥ the upper tertile of the reference range for the assay~Exclusion Criteria:~For All Aims:~1. Currently receiving treatment in an investigational device or drug study, or less than 30 days since ending treatment on an investigational device or drug study(s).~2. Currently receiving investigational procedures while participating in this study.~3. Patient with controlled PTH as defined by KDIGO as a PTH of 2 to 9 times the upper limit of normal of the assay.~4. Patients has received a bisphosphonate, denosumab or teriparatide during the 12 months prior to screening.~5. Anticipated or scheduled parathyroidectomy during the study period.~6. Patient has received a parathyroidectomy within 6 months prior to dosing.~7. Scheduled kidney transplant during the study period or anticipated living donor evaluation within three months of recruitment~8. Patient has an unstable medical condition based on medical history, physical examination, and routine laboratory tests, or is otherwise unstable in the judgment of the Investigator.~9. Bilateral lower extremity amputations or non-ambulatory~10. Metabolic bone diseases not related to the kidney (i.e., Pagets, Osteogenesis Imprefecta)~11. Untreated hyperthyroidism or hypoparathyroidism~12. Malignancy within the last 5 years (except non-melanoma skin cancers or cervical carcinoma in situ).~13. Patient is pregnant or nursing.~14. Patient 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 patient and Investigator's knowledge.~15. Weight \>300 pounds~For Aim 1 (Bone biopsy):~1. Allergy to tetracycline or demeclocycline.
