Kulindana: Community-friendly Delivery and Monitoring of TPT to Improve Uptake and Reduce TB Transmission

June 4, 2026 updated by: Adrienne E Shapiro, University of Washington

Kulindana: Expanding Access and Impact of Tuberculosis Preventative Therapy: Community-friendly Delivery and Monitoring of TPT to Improve Uptake and Reduce TB Transmission

The goal of this clinical trial is to learn if differentiated service delivery (DSD) of TB preventive therapy (TPT) improves uptake and completion of TPT in two populations: household contacts (HHC) of index TB patients and people living with HIV (PWH). The main questions it aims to answer are:

  • Is community-based and multi-month dispensing of short-course TPT with minimal clinic and laboratory monitoring associated with higher rates of initiation and completion of TPT, compared to standard of care, in both HHC and PWH?
  • Does community-based and DSD TPT reduce household and community TB transmission?

Researchers will compare DSD TPT delivery to standard of care (SoC) to see if DSD TPT delivery has an effect on TPT uptake and completion.

Participants will:

  • Be assessed for TPT eligibility through either DSD TPT service delivery of SoC including differentiated TB screening procedures.
  • If eligible, receive DSD TPT service delivery or SoC TPT service delivery.
  • Over 12 weeks receive either DSD or SoC TPT adherence assessment and follow-up.
  • Have TPT completion assessed at 12 weeks following enrolment.
  • A subset of participants will be assess for TB incidence at 9 months following enrolment.

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

The investigators will conduct a two-arm, non-blinded, randomized controlled trial (RCT) comparing differentiated TPT delivery to standard of care (SOC) clinic-based TPT. The central hypothesis is that decentralized, differentiated-service delivery approaches to TPT will improve TPT uptake and completion in Kenya. This study will be conducted in seven HIV clinics in Kisumu County, a high HIV/TB burden region in western Kenya. This study has two populations:

(A) Household contacts (HHC) of Index TB patients (Index patients: any age, diagnosed with pulmonary TB (or any TB if <18 years), who live with at least one other person not currently taking TB treatment). The TB index patients and household contacts include children.

(B) People living with HIV (PWH), aged 15+ who are eligible for TPT per Kenyan guidelines.

The primary outcome, 3 months after enrollment, is completion of a course of TPT, defined as taking 11 weeks of TPT within 16 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Household contacts (HHC) are eligible for enrolment if the participant shares a residential dwelling with an index TB patient and can provide informed consent (or parental consent, with assent if appropriate).
  • People living with HIV (PWH) are eligible for enrolment if the participant is an adult aged 15 and over, is eligible for TPT according to Kenyan National Guidelines, and can provide informed consent.

Exclusion Criteria:

  • HHC will be excluded if the participant plans on permanently relocating from the area within the next three months, is not willing to receive TPT screening and initiation at home, or is enrolled in any other investigational/interventional HIV or TB study.
  • PWH will be excluded if the participant plans on permanently relocating from the area within the next three months, has contraindications for TPT according to the Kenyan National Guidelines, or is enrolled in any other investigational/interventional HIV or TB study.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Differentiated service delivery (DSD) of TPT
In the household contact (HHC) population DSD TPT will be delivered at home in a single dispense of a full course of TPT; in the people living with HIV (PWH) population DSD TPT will be delivered at the clinic in a single dispense of a full course of TPT.
Other: Differentiated service delivery (DSD) of TB preventive therapy (TPT)
TPT is normally provided at clinics with monthly visits for refills, but the full course of TPT can also be provided all at once through differentiated service delivery (DSD) of TPT. By doing the Kulindana study, the investigators hope to learn which way of delivering TPT to participants (through usual clinic practice, or all at once) is best for helping participants finish a full course of TPT.
No Intervention: Clinic-based standard of care
Both the household contact (HHC) population and the people living with HIV (PWH) population have TPT dispensed at the clinic according to standard practice, typically one month at a time.
