简要总结

This trial is to describe the safety, tolerability and exposure-toxicity relationship of Depazolid given over 16 weeks, in combination with standard-dose Bedaquiline, Delamanid and Moxifloxacin, compared to standard-dose Bedaquiline, Delamanid and Moxifloxacin alone

详细描述

This will be an open label Phase IIb dose-finding, randomized, controlled study with a duration of 16 weeks of experimental therapy of Delpazolid(DZD) - Bedaquiline/Delamanid/ Moxifloxacin (BDM) in adult patients with newly diagnosed, smear positive, uncomplicated, drug sensitive pulmonary tuberculosis (TB) to evaluate the safety, efficacy, tolerability, pharmacokinetics and exposure/response-relationship of different doses of delpazolid in combination with bedaquiline, delamanid and moxifloxacin.

Participants will be randomized to one of five arms containing BDM standard dose with different doses of DZD.

入选标准

  • Provide written, informed consent prior to all trial-related procedures including HIV testing.
  • Male or female, aged between 18 and 65 years, inclusive.
  • Body weight between 40 and 90 kg, inclusive.
  • Newly diagnosed, previously untreated, drug susceptible pulmonary TB: presence of MTB complex and rapid molecular tests result confirming susceptibility to RIF and INH such as GeneXpert and/or HAIN MTBDR plus.
  • A chest X-ray (no older than 2 weeks) which, in the opinion of the Investigator, is consistent with TB.
  • Sputum positive on microscopy from concentrated sputum for acid-fast bacilli on at least one sputum sample (at least 1+ on the IUATLD/WHO scale).
  • The participant is willing to forgo consumption of foods high in tyramine for the period of taking study medication (See Appendix, section 20.2, page 92).
  • The participant is either unable to conceive/father children AND/OR his/her partner is unable to conceive/father children AND/OR they will consent to be using effective methods of contraception when engaging in heterosexual intercourse, as defined below:
  • a. Non-childbearing potential: i. Female participant/sexual partner of male participant: Bilateral oophorectomy, and/or hysterectomy or bilateral tubal ligation more than 12 months ago and/or has been postmenopausal with a history of no menses for at least 12 consecutive months ii. Male participant/sexual partner of female participant: Vasectomised or has had a bilateral orchidectomy minimally three months prior to screening iii. Male participants having a pregnant female partner or a male sexual partner: At least one barrier method has to be used in this case. b. Effective contraception methods: i. Female participants: Two methods, including methods that the patient's sexual partner(s) use. At least one must be a barrier method. Contraception must be practised for at least until 12 weeks after the last dose of DZD. ii. Male participants: Two methods, including methods that the patient's female sexual partner(s) use. At least one must be a barrier method. Effective contraception must be ensured for at least 16 weeks after the last dose of DZD.
  • Note: hormone-based contraception alone may not be reliable when taking RIF during continuation phase; therefore, hormone-based contraceptives alone cannot be used by female participants/female partners of male participants to prevent pregnancy.

Efficacy Outcome: Exposure-response Analysis With TTP (Time to Positive)_AUC0-24

时间窗: Week 0 - Week 16

The efficacy of DZD was evaluated by measuring the change in mycobacterial load over time on treatment as quantified by TTP (Time to positive) in BD MGIT960® liquid culture described by non linear mixed effects methodology. A population PK model was developed using NONMEM version 7.4.1. DZD PK is well-described by a two-compartment model with first-order absorption, first-order elimination and a proportional residual error. The final model included allometric scaling based on FFM.
