A Trial to Evaluate OPC 67683 in Participants With Pulmonary Sputum Culture-positive, Multidrug-resistant Tuberculosis (TB)
A Multi Center, Randomized, Double-blind, Placebo-controlled Phase 2 Trial to Evaluate the Safety, Efficacy and Pharmacokinetics of Multiple Doses of OPC 67683 in Patients With Pulmonary Sputum Culture-Positive, Multidrug-resistant Tuberculosis
This is a clinical trial to evaluate the safety and efficacy of OPC-67683 in the treatment of multidrug resistant tuberculosis (MDR TB) for 56 days. In addition to an optimized background regimen (OBR), participants will be randomized to receive:
- 100 mg OPC-67683 twice daily (BID)
- 200 mg OPC-67683 BID
- Placebo BID
After 56 days participants will complete their optimized background regimen (OBR).

Detailed Description
This is a multi center, randomized, double-blinded, stratified, placebo-controlled clinical trial in three parallel groups. Participants will be randomized to one of the following three treatment groups:
- OBR plus 100 mg OPC-67683 BID
- OBR plus 200 mg OPC-67683 BID
- OBR plus placebo BID
The three treatment groups will comprise approximately 140 participants each (male or female). The trial will consist of the following periods:
- Pre-treatment Period (Visits 1 to 3 [Day -9 to Day -1])
- Treatment Period (Visits 4 to 59 [Days 1 to 56])
- Post-treatment Period (Visits 60 to 64 [Days 57 to 84])
Enrolled participants (those accepted into the screening period of the trial who signed an informed consent form) will be stratified at randomization by extent of pulmonary TB; an equal number of participants with and without cavities visible in the lung fields on baseline chest radiograph will be allocated to each treatment group. A total of approximately 430 male or female participants aged 18 to 64 years, inclusive, with pulmonary, sputum culture-positive MDR TB (TB caused by Mycobacterium tuberculosis strains resistant to at least isoniazid and rifampicin) or with sputum smears positive for acid fast bacilli (AFB) and a positive rapid test for rifampicin resistance on direct sputum within 60 days prior to the expected date of enrollment. Participants with positive AFB smears and a positive rapid rifampicin resistance test will be enrolled as presumptively culture positive and withdrawn as ineligible if they are confirmed to not have sputum culture positive MDR TB.

---|---|---|
Percentage of Participants Who Achieved Sputum Culture Conversion (SCC) Using Solid Culture Media
Time Frame: From the first dose of study drug up to the end of the Post-treatment Follow-up Period (Up to Day 84)
|
A participant achieving SCC using solid culture media was defined as one with sputum culture negative for growth of MTB on Day 57, and (a) not followed by a positive culture at any point thereafter, and (b) confirmed by at least one additional negative sputum culture at Day 84.
|

Change From Baseline in Time to Culture Positivity Using the MGIT System
Time Frame: Baseline, Day 84
|
Mean change from baseline in time to culture positivity using the MGIT system was the value for "time to results" when a sputum culture result was positive (in days) using the MGIT system during the routine 42-day incubation period.
A longer time to culture positivity represented a lower burden of MTB organisms present in the sputum.
Baseline was defined as the average of Day -1 and Day 1 values, if the cultures on both days were positive; if only one culture was positive, the value for the positive culture was used as baseline.
|
Baseline, Day 84
|
Area Under the Curve (AUC) of Change From Baseline in Time to Culture Positivity in the MGIT System
Time Frame: Baseline to Day 57
|
AUC of change from baseline for time to culture positivity (i.e., TTD) (Days 0 to 57), summarizes overall participant response for treatment period.
Larger AUC of change from baseline for time to culture positivity would strongly suggest a clinical response with reduction of burden of MTB organisms in sputum.
For this analysis, ti=visit day of each visit; t0=Day 0, t1=Day 8, t2=Day 15, etc. and xi=change from baseline in time to culture positivity at each visit; AUC at each visit was determined as AUCi=(ti - ti-1)(xi+ xi-1)/2.
Average AUC of change from baseline was the sum of all AUCi divided by a given participant's duration in the trial up to 57 days.
Baseline (Day 0)=the average of Day -1 and Day 1 values, if cultures on both days were positive; if only one culture was positive, value for time to culture positivity for positive culture was used as baseline.

Percentage of Participants Who Achieved SCC From the MGIT System Analyzed by Cochran-Armitage Linear Trend Test for Dose-response Relationship
Time Frame: From the first dose of study drug up to the end of the Post-treatment Follow-up Period (Up to Day 84)
|
A participant achieving SCC using solid media is defined as one with sputum culture negative for growth of MTB on Day 57, and (a) not followed by a positive culture at any point thereafter, and (b) confirmed by at least one additional negative sputum culture at Day 84.
A dose response in the percentage of participants achieving SCC using the MGIT system was tested by the Cochran-Armitage linear trend test with equally spaced dose scores (0, 1, and 2 for placebo, 100 mg BID, and 200 mg BID, respectively).
|
From the first dose of study drug up to the end of the Post-treatment Follow-up Period (Up to Day 84)

Percentage of Participants Who Achieved Initial SCC Using the MGIT System
Time Frame: Day 57
|
Initial SCC occurred at the time of the collection of the first sputum specimen with mycobacterial culture negative for growth of MTB using the MGIT system followed by at least one additional MGIT negative sputum specimen at least 27 days after the first negative specimen and no sputum specimens MGIT positive for growth at any point between the negative MGIT sputum specimens.
Survival analysis methodology was performed to compare the Kaplan-Meier curves for time to SCC across 3 treatment groups.
Comparisons between 100 mg BID and placebo and 200 mg BID and placebo were also performed with stratified log-rank tests.
The benefit ratios (ratio of likelihoods that participants treated with delamanid BID + OBR would achieve SCC more rapidly than participants treated with placebo + OBR) for participants achieving SCC were computed.

The concomitant anti-TB medication were classified as per WHO 2008 guidelines and included: Category 1- first-line oral anti-tuberculosis drugs; Category 2- injectable anti-tuberculosis drugs; Category 3- fluoroquinolones; Category 4- oral bacteriostatic second-line anti-tuberculosis drugs; Category 5- anti-tuberculosis drugs with unclear efficacy or unclear role in MDR-TB treatment (not recommended by WHO for routine use in MDR-TB participants).

From first dose of study drug up to post treatment period (Day 84)
|
Percentage of Participants With At Least One Treatment-Emergent Adverse Events (TEAEs)
Time Frame: From first dose of study drug up to post treatment period (Day 84)
|
An adverse event (AE) was defined as any untoward medical occurrence in a clinical trial participant and which does not necessarily have a causal relationship with the treatment.
An AE can therefore be any unfavorable and unintended sign (including e.g., an abnormal laboratory assessment result), symptom or disease temporally associated with participation in the clinical trial, whether or not it is considered causally related to the medicinal product or procedures of the clinical trial.
A clinically significant worsening in the health of the participant compared with the participant's health status documented at baseline constituted a TEAE.
