Pharmacokinetics of Sofosbuvir/Daclatasvir in HCV-infected Lactating Women

August 21, 2022 updated by: Manal Hamdy El-Sayed, Ain Shams University

Pharmacokinetics of Sofosbuvir/Daclatasvir in HCV-infected Lactating Women: a Pilot Study

This is a prospective, observational, open-label, pharmacokinetic study will evaluate PK of SOF/DAC in lactating HCV-infected females at weaning or women who voluntarily decided to forego breastfeeding to initiate HCV infection treatment. Therefore, drug concentrations can be determined in maternal plasma and milk without risk to the children. HCV infected women at weaning after various durations of breastfeeding and HCV infected women who wish to initiate treatment immediately after delivery and forego breastfeeding will be recruited to start treatment under the guidance of their physician with SOF/DAC to determine M/P ratios of each of SOF, GS-331007 and DAC.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Eligible women will be advised to arrange for initiation of treatment with their physician once they decide to stop breastfeeding. Treatment will be initiated once the women decide to wean their children and a warning will be given to abstain from any breast-feeding once treatment is started. This treatment is prescribed by the physician either the patients choose to participate in the study or not. In addition, effective contraceptive methods should be used. The treatment consists of SOF/DAC: 400 mg sofosbuvir and 60 mg daclatasvir administered with food for 12 weeks.

All recruited patients will be screened for the following data at baseline: Serum creatinine, bilirubin, albumin, AST, ALT, prothrombin time (PT), CBC, and viral load by PCR. The patient's general and demographic information (age, gender, height, and weight), comorbidities, and concurrent medications will be assessed and recorded in a specially designed patient data sheet.

The study will be conducted in the Faculty of Medicine Ain-Shams Research Institute Clinical Research Center (MASRI -CRC). After the first dose, women will be instructed to express their milk and discard it on the first two days and come to the research center on the third day for plasma and milk sampling. Patients will be instructed to take the dose on time especially the day before sampling. They will be asked to record the time of dose administration. They might be also followed up by telephone calls

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Lactating HCV infected female patients

  • Relevant history or current condition that might interfere with drug absorption, distribution, metabolism or excretion except for conditions related to HCV.
  • Clinically relevant low hemoglobin concentration at screening.
  • Pregnancy
