A Randomized Controlled Trial of Ivermectin Monotherapy versus Hydroxychloroquine, Ivermectin, and Azithromycin Combination Therapy in COVID-19 Patients in Nigeria
Small RCT with 61 patients in Nigeria, all patients treated with ivermectin, zinc, and vitamin C, showing no significant improvements in recovery with the addition of HCQ+AZ.

The efficacy of Ivermectin (IVM) against SARS-CoV-2 has
been demonstrated in vitro, while several clinical studies
suggest that it is efficacious and safe in reducing morbidity
and mortality. Hydroxychloroquine (HCQ, Quinoric®), IVM
and Azithromycin(AZM, Zithromax®) (HIA therapy) is being
used in several low- and middle-income countries (LMIC)
where more expensive medications such as Remdesivir are
out of reach. In this study, we set out to compare the efficacy
of IVM monotherapy with HIA combination therapy.
Methods: This was a single-blind, randomized control trial,
of 2 parallel groups of COVID-19 Positive Nigerians. Thirty
(30) patients received Ivermectin (Mectizan®) 200 mcg/
kg daily for five days, while 31 patients received HIA triple
therapy. Viral cycle threshold (Ct) at pre-treatment baseline,
and days 2, 5, 14 and 21 were measured for E- and
N-genes (Envelope and Nucleocapsid genes respectively).
SpO2 (percentage saturation of oxygen in the blood) was
assessed on a daily basis, while inflammatory markers
such as Erythrocyte Sedimentation Rate (ESR), C-Reactive
Protein, and D-dimer and Neutrophil/Lymphocyte Ratios
(NLR), were assessed at baseline and day 7 post treatment.
Clinical status was self-assessed daily on a Likert scale.
Results: 2-way Repeated measures Analysis of Variance
(RMANOVA) did not show any difference between the
two groups. However, there was a significant time effect
(improvement over time) for SpO2, Ct N-gene, Ct E-gene
and clinical status in both groups, and significant reductions
in inflammatory markers by day 7 (P < 0.0001).
Conclusions: AZT + HCQ may be redundant adjuncts
in COVID-19 therapy. Improvements noted are likely due
in large part to Ivermectin virucidal and anti-inflammatory
is less effective
