PRIMARY outcome

Timeframe: 21 days

Population: Intention to treat population infected with Trichuris trichiura from both Phase II and Phase III of the study (n=636). A separate efficacy analysis by phase was not conducted, as the protocol specifies that the required sample size for this outcome is derived from all participants infected with T. trichiura at baseline, combining those from Phase II and Phase III.

For Trichuris trichiura, the cure rate is defined as the proportion of participants who test negative for T. trichiura eggs in the Kato-Katz fecal examination on day 21 post-treatment, relative to the total number of participants infected at baseline (n=636).

SECONDARY outcome

Timeframe: 21 days

Population: Intention to treat population infected with Trichuris trichiura from both Phase II and Phase III of the study (n=636). A separate efficacy analysis by phase was not conducted, as the protocol specifies that the required sample size for this outcome is derived from all participants infected with T. trichiura at baseline, combining those from Phase II and Phase III.

The Egg Reduction Rate (ERR) is defined as the percentage reduction in the geometric mean (GM) of eggs per gram (EPG) of feces from baseline to post-treatment.

Population: Intention to treat population infected with hookworm from Phase III of the study (n=350). A separate efficacy analysis by phase was not conducted, as the protocol specifies that the required sample size for this outcome is derived exclusively from participants infected with hookworms at baseline in Phase III.

For hookworm, the cure rate is defined as the proportion of participants who test negative for hookworm eggs in the Kato-Katz fecal examination on day 21 post-treatment, relative to the total number of participants infected at baseline in Phase III (n=350).

SECONDARY outcome

Timeframe: 21 days

Population: Although samples were collected from participants, they were not analyzed and will not be analyzed in the future, as emerging scientific evidence has invalidated the hypothesis.

The original objective as per the protocol was to "To evaluate the frequency of known ALB resistant alleles in hookworm and T. trichiura in the three treatment arms before and after treatment" with the endpoint being "Evaluation of genotypic albendazole resistance in the three arms." This objective was based on the hypothesis that mutations at codons 167, 198, and 200 of the beta-tubulin gene of Trichuris trichiura were associated with resistance. However, since this time, it has become increasingly evident, based on research from us (PMID: 35895348, 39546832, 34563247) and others, that this hypothesis is no longer supported, and that the genetic determinants of resistance in T. trichiura are yet to be discovered. Therefore, we have begun evaluating, using whole genome sequencing, other genetic variants and their association with poor treatment response. This research is exploratory and ongoing. Therefore, the original outcome as defined in the protocol could not be assessed.
