Abstract
Background: Drug-resistant tuberculosis remains a major obstacle in ending the global tuberculosis epidemic. Deployment of molecular tools for comprehensive drug resistance profiling is imperative for successful detection and characterisation of tuberculosis drug resistance. We aimed to assess the diagnostic accuracy of a new class of molecular diagnostics for drug-resistant tuberculosis.
Methods: We conducted a prospective, cross-sectional, multicentre clinical evaluation of the performance of two targeted next-generation sequencing (tNGS) assays for drug-resistant tuberculosis at reference laboratories in three countries (Georgia, India, and South Africa) to assess diagnostic accuracy and index test failure rates. Eligible participants were aged 18 years or older, with molecularly confirmed pulmonary tuberculosis, and at risk for rifampicin-resistant tuberculosis. Sensitivity and specificity for both tNGS index tests (GenoScreen Deeplex Myc-TB and Oxford Nanopore Technologies [ONT] Tuberculosis Drug Resistance Test) were calculated for rifampicin, isoniazid, fluoroquinolones (moxifloxacin, levofloxacin), second line-injectables (amikacin, kanamycin, capreomycin), pyrazinamide, bedaquiline, linezolid, clofazimine, ethambutol, and streptomycin against a composite reference standard of phenotypic drug susceptibility testing and whole-genome sequencing.
Findings: Between April 1, 2021, and June 30, 2022, 832 individuals were invited to participate in the study, of whom 720 were included in the final analysis (212, 376, and 132 participants in Georgia, India, and South Africa, respectively). Of 720 clinical sediment samples evaluated, 658 (91%) and 684 (95%) produced complete or partial results on the GenoScreen and ONT tNGS workflows, respectively, with 593 (96%) and 603 (98%) of 616 smear-positive samples producing tNGS sequence data. Both workflows had sensitivities and specificities of more than 95% for rifampicin and isoniazid, and high accuracy for fluoroquinolones (sensitivity approximately ≥94%) and second line-injectables (sensitivity 80%) compared with the composite reference standard. Importantly, these assays also detected mutations associated with resistance to critical new and repurposed drugs (bedaquiline, linezolid) not currently detectable by any other WHO-recommended rapid diagnostics on the market. We note that the current format of assays have low sensitivity (≤50%) for linezolid and more work on mutations associated with drug resistance is needed.
Interpretation: This multicentre evaluation demonstrates that culture-free tNGS can provide accurate sequencing results for detection and characterisation of drug resistance from Mycobacterium tuberculosis clinical sediment samples for timely, comprehensive profiling of drug-resistant tuberculosis.

Version changes
11-August-2025: Added additional data file to include tNGS results, WGS calls, pDST, and clinical metadata. "WEIGHT" data column was rounded to the nearest 5 to protect participant privacy, and "GENDER" data column was converted to numeric binary values to protect participant privacy. The readme file was updated.
Human subjects data
This dataset has been de-identified and is publicly available in accordance with participant consent and ethical research standards. All participants provided informed consent for their de-identified data to be shared in a public data repository for the purposes of scientific research and transparency.
De-identification was carried out by removing all direct identifiers and indirect identifiers. Additionally, all free-text fields were reviewed to ensure that no potentially identifying information was retained. The dataset was reviewed to confirm that no combination of variables could reasonably lead to re-identification of individual participants.
Participants meeting eligibility criteria were asked to provide at least 6 mL sputum either in one or two samples collected on day 1 and day 2. Samples were homogenized, decontaminated, re-suspended in 4mL final volume for all downstream testing. MTB/RIF, acid-fast bacilli (AFB) smear, Hain MTBDRplus and MTBDRsl, Mycobacteria Growth Indicator Tube (MGIT) and Löwenstein–Jensen medium (LJ) culture were performed on the sediment for standard of care testing. MGIT pDST was performed for all culture-positive samples for RIF, INH, FQ (MFX, LFX), PZA, AMK, CAP, KAN, BDQ, LZD, CLF, STR, and EMB at WHO endorsed critical concentrations.
