Pharmacokinetic and Pharmacodynamic Study of Bococizumab Alone and When Combined With Recombinant Human Hyaluronidase

Phase 1
Terminated
Conditions
Hypercholesterolemia
Healthy
Registration Number
NCT02667223
Lead Sponsor
Pfizer
Brief Summary

This is a Phase 1, open-label, single-dose, randomized, dose escalation study in healthy and hypercholesterolemic subjects. Each subject will receive 1 of 5 treatments as a single subcutaneous injection. Subjects will remain confined at the research clinic for approximately 2 days. After discharge, subjects will return to the research clinic 15 times during 12 weeks.

Inclusion Criteria
  • Healthy and hypercholesterolemic subjects between the ages of 18 and 65 years.
  • Healthy subjects must have fasting LDL-C >/= 70 to </= 190 mg/dL at two qualifying visits.
  • Hypercholesterolemic subjects must be on a stable daily dose of statin for at least 45 days before dosing and fasting LDL-C must be >/= 70 mg/dL.
Exclusion Criteria
  • Use of prescription or non-prescription drugs within 7 days or 5 half-lives (whichever) is longer prior to the first dose of study medication. For hypercholesterolemic subjects the use of statin class medication is allowed.
  • Prior exposure to bococizumab (also known as PF-04950615 or RN316) or other investigational PCSK9 inhibitors.
  • Treatment with monoclonal antibodies within 6 months or 5 half-lives (whichever is longer) before dosing.

Primary Outcome Measures
NameTimeMethod
Cmax of bococizumabDay 1 - Day 85

Maximum Observed Plasma Concentration (Cmax)

AUCinf of bococizumabDay 1 - Day 85

Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - ∞), if data permits (otherwise AUClast will be used).

Secondary Outcome Measures
NameTimeMethod
AUEC85Baseline up to Day 85

Area under the LDL-C concentration-time curve calculated using absolute LDL-C values

Laboratory testsBaseline up to Day 85

Incidence of abnormal and clinically relevant safety laboratory tests including clinical chemistry and hematology

LDL-C at Week 4Baseline to Week 4

Absolute value, and absolute change and % change in LDL cholesterol at Week 4 following bococizumab administration alone and when co-mixed with rHuPH20.

CL/FDay 1 - Day 85

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Apparent clearance is influenced by the fraction of the dose absorbed. Clearance is estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Vz/FDay 1 - Day 85

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after dose (Vz/F) is influenced by the fraction absorbed.

Tmax, LDL-CBaseline up to Day 85

Time to MaxELDL-C calculated using absolute LDL-C values

AEsBaseline up to Day 85

Incidence, severity, and causal relationship of treatment-emergent adverse events (TEAEs)

Vital signsBaseline up to Day 85

Incidence of abnormal and clinically relevant vital signs

AUClast of bococizumabDay 1 - Day 85

Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

ADADay 1 - Day 85

Incidence and titer of Anti-Drug Antibodies (ADA) following administration of bococizumab alone and when co-mixed with rHuPH20.

TmaxDay 1 - Day 85

Time to Reach Maximum Observed Plasma Concentration (Tmax)

t1/2Day 1 - Day 85

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

MaxELDL-CBaseline up to Day 85

Maximum LDL-C lowering calculated using absolute LDL-C values

nAbDay 1- Day 85

Incidence and titer of neutralizing antibodies (nAb), if applicable, following administration of bococizumab alone and when co-mixed with rHuPH20.
