Webinar: Approaches for improving inference from observational multi-drug resistant tuberculosis (MDR-TB) treatment cohorts

On Monday, January 27th from 08:00 to 9:00 EST (13:00-14:00 CET) RESIST-TB hosted a presentation from Molly Franke, ScD, Associate Professor of Global Health and Social Medicine, Harvard Medical School, and Carly Rodriguez, MPH, PhD Candidate in Epidemiology, Boston University School of Public Health.

Description: Observational data from MDR-TB cohorts is a critically valuable resource for answering urgent clinical questions in the absence of evidence from randomized trials. We will present novel methodological approaches, commonly used in other disciplines, that could be used to improve inference from MDR-TB treatment cohorts and identify the data gaps and challenges that must be overcome to implement them.

Moderator: Carole Mitnick, ScD, Associate Professor of Global Health and Social Medicine, Harvard Medical School.

Combined Use of DLM and BDQ on MDR-TB

On April 5th, Dr. Cathy Hewison and Dr. Lorenzo Guglielmetti presented a webinar on the current evidence and practices for the combined use of delamanid and bedaquiline for the treatment of MDR-TB.

Today, more and more clinicians around the world are experienced in using DLM and BDQ as part of a longer MDR-TB regimens with good results. However, there is less experience in using delamanid and bedaquiline together in the same MDR-TB treatment regimen due to concerns about the common effects on the QT interval. This webinar covered the current clinical practice and results of use of MDR-TB regimens containing the DLM and BDQ combination from endTB, MSF and Europe, as well an overview of the latest publications and the ongoing studies and trials.

LAM as a Pharmacodynamic Biomarker and Drug Development Tool for TB

On June 22nd, 2017, Dr. Yongge Liu, Director of Diagnostics at Otsuka Novel Products, gave a presentation on LAM (Lipoarabinomannan) as a Pharmacodynamic Biomarker and Drug Development Tool for TB. 

Otsuka Pharmaceutical is developing an assay that can measure the concentration of LAM, which is showing promise as a biomarker of the load of viable tubercle bacilli in sputum. The assay shows potential for real-time evaluation of treatment response in clinical trials, and Otsuka is working with the Critical Path to TB Drug Regimens (CPTR) to seek qualification of this biomarker as a drug development tool by the FDA in the USA and as a drug development method by the EMA in the European Union. Yongge Liu, the Director of Diagnostics at Otsuka Novel Products, will discuss the development of this assay and the biomarker qualification process.

Identification of Patients Who Could Benefit from Bedaquiline or Delamanid

On March 16th, 2016, Maryline Bonnet gave a presentation entitled "Identification of Patients Who Could Benefit from Bedaquiline or Delamanid."

WHO recommends adding bedaquiline or delamanid when a multidrug-resistant tuberculosis (MDR-TB) regimen with four effective drugs cannot be designed and delamanid in patients with high risk of poor outcomes. Based on a retrospective cohort study of outcomes of treatment of MDR-TB patients in programmes in Uzbekistan, Georgia, Armenia, Swaziland and Kenya, we aimed to identify patients at risk of unfavourable outcomes who may benefit of the new drugs. Of 1433 patients, 48.5% had body mass index (BMI) below 18.5Kg/m2, 72.9% high bacillary load, 16.7% harboured strains resistant to two injectables, 2.9% to ofloxacin, and 3.0% had extensively DRTB (XDR-TB). XDR-TB; resistance to two injectables or ofloxacin; imprisonment in the past; 2nd line drugs treatment history low BMI and high bacillary load were independently associated with unfavourable outcomes. In our cohort, patients who may benefit of the new drugs represented up to two thirds of all MDR-TB patients.

Clofazimine – Repurpose & Strategy

On January 29th, 2016  Novartis Pharma's Roxana Drake, MD PhD gave a presentation entitled Clofazimine –Repurpose & Strategy.

Novartis study CLAM320b2202 is a 30 month multi-center, phase 2b/3 randomized, open label trial to evaluate the efficacy and safety of clofazimine in patients with multidrug-resistant pulmonary tuberculosis. Patients will be randomized into one of two treatment arms. The experimental arm being the administration of 200 mg of clofazimine once daily in addition to the background regimen for 18 weeks followed by 100 mg clofazimine one daily in addition to the background regimen for the remainder of the 24-month treatment period. The control arm will only receive the background regimen for the entire 24-month treatment period. Both arms will undergo a 6 month follow up period.

The primary end points are to evaluate the effect of clofazimine when administrated orally in addition to background regimen compared to background regimen alone in producing higher cure rates at month 30 based on liquid culture media results in mycobacterial grown indicator tube (MGIT). The study will also assess the drugs effect on time to sputum culture conversion at week 24 using liquid culture media, the proportion of patients achieving sputum culture conversion at week 2, time to positive signal of MTB growth in liquid culture media, the drugs safety and tolerability, and routine safety EKG parameters. This study also contains a substudy that will examine the pharmacokinetic and pharmacodynamic characteristics of clofazimine, determine systemic trough concentrations of antiretroviral drugs co-administered with clofazimine, and explore the relationship between clofazimine concentration estimated using dried-blood spot methodology and traditional bioanalytical methods. The substudy will also assess the relationship between clofazimine plasma concentrations versus ECG parameters on Day -1 and Day 127 to evaluate differences in study arms and analyze serial sputum colony count during first 24 weeks of treatment.

This study plans to enroll 380 patients in multiple TB treatment centers worldwide to yield 310 patients, both male and female ages 14 to 70 years with 155 patients per arm. Enrollment will start on March 31st 2016 and will end on March 28th 2018. The treatment period will conclude on July 30th 2020 and follow ups will conclude in December 2020.
