Summary of COVID-19 miscellaneous studies

260 patient NaCl early treatment RCT: 71% lower progression (p<0.0001) and 97% lower severe cases (p<0.0001).
RCT 379 mild COVID-19 cases showing significantly lower prevalence and severity of olfactory and gustatory dysfunction with budesonide nasal spray, chlorhexidine mouthwash, and saline nasal irrigation. The control group received no intervention, the saline group received saline nasal irrigation plus saline nasal spray and mouthwash, and the drug group received saline nasal irrigation plus budesonide nasal spray and chlorhexidine mouthwash. Saline nasal irrigation plus nasal spray and mouthwash were administered once and four times daily, respectively. Both treatment groups had significantly lower prevalence and severity olfactory and gustatory dysfunction. Prevalence was lower for the drug vs. saline group, without statistical significance.

2. Martin et al., Oral Probenecid for Nonhospitalized Adults with Symptomatic Mild-to-Moderate COVID-19

75 patient probenicid early treatment RCT: 90% improved recovery (p<0.0001) and 36% faster viral clearance (p=0.0001).
RCT 75 outpatients in India with mild to moderate COVID-19 showing faster viral clearance, faster time to symptom resolution, and improvement in disease progression with probenecid treatment for 5 days compared to placebo. Probenecid was well tolerated with only mild adverse events noted. There was a dose-dependent response, with probenecid 1000mg twice daily performing better than 500mg twice daily.

3. Holubovska et al., RNA Polymerase Inhibitor Enisamium for Treatment of Moderate COVID-19 Patients: A Randomized, Placebo-Controlled, Multicenter, Double-Blind Phase 3 Clinical Trial

285 patient enisamium late treatment RCT: 86% lower mortality (p=0.25), 75% lower progression (p=0.03), 9% faster improvement (p=0.01), and 89% higher hospital discharge (p=0.12).
RCT 592 hospitalized moderate COVID-19 patients in Ukraine showing improved recovery and lower progression with enisamium. The trial initially included patients with moderate COVID-19 not requiring oxygen, but a mid-trial change was made to exclude this group due to a lack of benefit, and results are reported for the patients requiring oxygen. The greatest benefit was seen in patients treated within 5 days of symptom onset.

RCT 189 hospitalized COVID-19 patients showing lower mortality and faster recovery with spirulina. Spirulina treatment also resulted in greater reductions in inflammatory markers such as IL-6, TNF-a, IP-10, CRP, ESR, and ferritin. All patients received remdesivir.

Open-label non-randomized trial with 80 participants exposed to confirmed SARS-CoV-2 cases, showing lower risk of infection and milder symptoms with mitoquinone mesylate (Mito-MES) prophylaxis. 40 participants took Mito-MES 20mg daily for 14 days, starting within 5 days of exposure, while 40 did not take Mito-MES. 30% of Mito-MES participants tested positive for SARS-CoV-2 compared to 75% of controls. None of the participants who started Mito-MES within 72 hours developed infection, compared to 12 who started on days 3-5. There was no hospitalization in either group.

Randomized controlled trial of 111 hospitalized COVID-19 patients in Iran showing significantly shorter hospital stay, higher oxygen saturation, and lower respiratory rate at discharge with azithromycin plus hydroxychloroquine and lopinavir/ritonavir compared to hydroxychloroquine and lopinavir/ritonavir alone. There were no significant differences in ICU admission, intubation, or mortality, although there was a trend towards lower ICU admission with azithromycin (3.6% vs. 12.7%, p = 0.07). Patients with prior cardiac disease were excluded. The study is limited by the small sample size and open-label design.

RCT 98 outpatients in Brazil, showing faster recovery from cough with inhaled hypertonic saline. Authors note that the effect on coughing may hypothetically be related to a hyperosmotic response influencing the function of different membrane channels and preventing virus entry into the cells; and that the hypertonic solution may increase mucociliary clearance and reduce the destructive inflammatory process in the airways with a decrease in respiratory symptoms.

Late stage RCT of 667 hospitalized patients with up to 14 days of symptoms at enrollment and receiving up to 4 liters per minute supplemental oxygen, not finding a significant effect after 15 days. Authors note: "the trial cannot definitively rule out either a substantial benefit of the trial drugs or a substantial harm", sample sizes are too small. The paper uses the terms mild and moderate, however all patients had serious enough disease to be hospitalized, and 14% were actually randomized in the ICU. The trial had significant protocol deviations and unusually low medication adherence. Authors note: "our aim was to exclude patients already receiving longer and potentially therapeutic doses of the study treatments" in explanation for why the study protocol was changed to exclude patients with previous use of the medications >24hrs. Analyzing these patients rather than excluding them may have revealed effectiveness with early use as shown in other studies. The..

917,198 patient azithromycin late treatment study: 32% lower mortality (p<0.0001).
Retrospective study of 917,198 hospitalized COVID-19 cases covered by the Iran Health Insurance Organization over 26 months showing that antithrombotics, corticosteroids, and antivirals reduced mortality while diuretics, antibiotics, and antidiabetics increased it. Confounding makes some results very unreliable. For example, diuretics like furosemide are often used to treat fluid overload, which is more likely in ICU or advanced disease requiring aggressive fluid resuscitation. Hospitalization length has increased risk of significant confounding, for example longer hospitalization increases the chance of receiving a medication, and death may result in shorter hospitalization. Mortality results may be more reliable. Confounding by indication is likely to be significant for many medications. Authors adjustments have very limited severity information (admission type refers to ward vs. ER department on initial arrival). We can estimate the impact of confounding from typical usage..

Small RCT comparing the addition of AZ for very late stage patients on ventilation or oxygen. One notable result is that even within this extremely late stage population, results suggest increased efficacy with the addition of AZ for patients with earlier use of AZ/HCQ, OR 0.71 [0.25-2.03] (Figure S4). Patients received 8g of HCQ over 10 days, approaching the high levels used in the RECOVERY trial (9.2g over 10 days), showing significantly more adverse events than typical trials. 50% of patients were on mechanical ventilation at baseline. More than the increase in mortality at day 29 occurred on day 0, and more than 3x the increase occurred by day 2.

Low risk patient RCT for HCQ+AZ and HCQ vs. control, not showing any significant differences. Authors note that the results are not applicable to higher risk patients, that positive PCR may simply reflect detection of inactive (non-infectious) viral remnants, that an alternative dosage regimen may be more effective, and that medication adherence was unknown. HCQ dosing was 600mg/day for 1 week, therapeutic levels may not be reached for several days. There were no deaths or serious adverse events. Viral load was already very high at baseline.

RCT 1,126 patients in Brazil showing no significant differences with low dose spirulina. The dose used was 7.6 times lower than the dose used by [Aghasadeghi] which shows significantly lower mortality. eFigure 1 shows 12 events in the treatment group before the first event in the placebo group. The probability of this happening is very low, ~ 0.001. One possible cause would be if some process resulted in patients expected to visit the ER soon being more likely to be placed in the treatment group. (Another possibility is treatment side effects causing ER visits, however the were fewer adverse events and fewer severe adverse events in the treatment group).
