Study population: The study consisted of two phases. In phase 1, each site was sent a different set of 200 clinical isolates from the Research and Training in Tropical Diseases and Institute for Tropical Medicine collections (ITM). In phase 2, samples from 274 patients recruited between Azerbaijan and Moldova were tested in Germany, while samples from 214 (locally-recruited) patients were tested in South Africa.

About this study

Official title: Multi-center Study to Assess the Non-inferiority of YD REBA MTB-MDR® and Hain GenoType® MTBDRplus V2 Line Probe Assays Compared to Hain GenoType® MTBDRplus V1

This is a multi-center, blinded study to determine the performance of the YD Diagnostic Corporation (YD) REBA MTB-MDR® and Hain Genotype MTBDRplus V2 kit in a total of 600 clinical isolates and 900 residual sputum samples from patients with symptoms of pulmonary TB (PTB) and at risk of drug resistance. All testing was done on stored, de-identified leftover samples.

The study involved three World Health Organization (WHO) Supranational Reference Laboratories with well-characterized strain collections and access to sputum samples with significant rates of drug resistance.

Being tested
YD REBA MTB-MDR, Hain Genotype MTBDRplus V1, Hain Genotype MTBDRplus V2

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • YD REBA MTB-MDRDevice

    Conducted on stored, de-identified leftover samples. A line probe assay designed for detection of Multidrug-resistant tuberculosis (MDR-TB). The REBA MTB-MDR® assay is a qualitative in vitro test for the identification of Mycobacterium tuberculosis (MTB) complex and its susceptibility to rifampin and isoniazid from cultured samples and smear positive specimens.

  • Hain Genotype MTBDRplus V1Device

    Conducted on stored, de-identified leftover samples. There is only one Line Probe Assay for molecular MTB drug resistance globally available, the GenoType® MTBDRplus V.1 from Hain Lifescience. This assay includes rpoB gene probes for Rifampin (RIF) resistance, katG gene probes for high level Isoniazid (INH) resistance, and inhA gene probes for determination of low level INH resistance

  • Hain Genotype MTBDRplus V2Device

    Conducted on stored, de-identified leftover samples. An updated version of the Hain Genotype MTBDRplus V1 assay, the Genotype MTBDRplus V.2 line probe assay, showed increased sensitivity for MTB detection in the 2 studies published so far

Study groupRoleWhat they receive
All SubjectsAll strains in Phase 1 and all Sputum samples in Phase 2 were tested with Hain Genotype MTBDRplus V1, Hain Genotype MTBDRplus V2, and YD REBA MTB-MDR diagnostic tests. Investigators and Operators were blinded to all other results for a sample upon data entry.
Receives: Device: YD REBA MTB-MDR; Device: Hain Genotype MTBDRplus V1; Device: Hain Genotype MTBDRplus V2

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. INH/RIF Resistance Detection

    Measured: At the end of study 9-10 Months after the Study started

Secondary outcomes (1)
  1. Multi-Drug Resistant TB detection

    Is the subject resistant to both INH and RIF

    Measured: At the end of study 9-10 Months after the Study started

Questions about this trial

What is this clinical trial studying?

An observational study of Multidrug-Resistant Tuberculosis and Isoniazid Resistant Pulmonary Tuberculosis, run by Foundation for Innovative New Diagnostics, Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

INH/RIF Resistance Detection (time frame: At the end of study 9-10 Months after the Study started). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2026.
