Abstract
BACKGROUND The evidence for whether ivermectin impacts recovery, hospital admissions, and longer-term outcomes in COVID-19 is contested. The WHO recommends its use only in the context of clinical trials. METHODS In this multicentre, open-label, multi-arm, adaptive platform randomised controlled trial, we included participants aged ≥18 years in the community, with a positive SARS-CoV-2 test, and symptoms lasting ≤14 days. Participants were randomised to usual care, usual care plus ivermectin tablets (target 300-400 μg/kg per dose, once daily for 3 days), or usual care plus other interventions. Co-primary endpoints were time to first self-reported recovery, and COVID-19 related hospitalisation/death within 28 days, analysed using Bayesian models. Recovery at 6 months was the primary, longer term outcome. TRIAL REGISTRATION ISRCTN86534580. FINDINGS The primary analysis included 8811 SARS-CoV-2 positive participants (median symptom duration 5 days), randomised to ivermectin (n = 2157), usual care (n = 3256), and other treatments (n = 3398) from June 23, 2021 to July 1, 2022. Time to self-reported recovery was shorter in the ivermectin group compared with usual care (hazard ratio 1·15 [95% Bayesian credible interval, 1·07 to 1·23], median decrease 2.06 days [1·00 to 3·06]), probability of meaningful effect (pre-specified hazard ratio ≥1.2) 0·192). COVID-19-related hospitalisations/deaths (odds ratio 1·02 [0·63 to 1·62]; estimated percentage difference 0% [-1% to 0·6%]), serious adverse events (three and five respectively), and the proportion feeling fully recovered were similar in both groups at 6 months (74·3% and 71·2% respectively (RR = 1·05, [1·02 to 1·08]) and also at 3 and 12 months. INTERPRETATION Ivermectin for COVID-19 is unlikely to provide clinically meaningful improvement in recovery, hospital admissions, or longer-term outcomes. Further trials of ivermectin for SARS-Cov-2 infection in vaccinated community populations appear unwarranted. FUNDING UKRI/National Institute of Health Research (MC_PC_19079).

Abstract
Viral clearance, antibody response and the mutagenic effect of molnupiravir has not been elucidated in at-risk populations. Non-hospitalised participants within 5 days of SARS-CoV-2 symptoms randomised to receive molnupiravir (n = 253) or Usual Care (n = 324) were recruited to study viral and antibody dynamics and the effect of molnupiravir on viral whole genome sequence from 1437 viral genomes. Molnupiravir accelerates viral load decline, but virus is detectable by Day 5 in most cases. At Day 14 (9 days post-treatment), molnupiravir is associated with significantly higher viral persistence and significantly lower anti-SARS-CoV-2 spike antibody titres compared to Usual Care. Serial sequencing reveals increased mutagenesis with molnupiravir treatment. Persistence of detectable viral RNA at Day 14 in the molnupiravir group is associated with higher transition mutations following treatment cessation. Viral viability at Day 14 is similar in both groups with post-molnupiravir treated samples cultured up to 9 days post cessation of treatment. The current 5-day molnupiravir course is too short. Longer courses should be tested to reduce the risk of potentially transmissible molnupiravir-mutated variants being generated. Trial registration: ISRCTN30448031.

Abstract
INTRODUCTION There is an urgent need to determine the safety, effectiveness and cost-effectiveness of novel antiviral treatments for COVID-19 in vaccinated patients in the community at increased risk of morbidity and mortality from COVID-19. METHODS AND ANALYSIS PANORAMIC is a UK-wide, open-label, prospective, adaptive, multiarm platform, randomised clinical trial that evaluates antiviral treatments for COVID-19 in the community. A master protocol governs the addition of new antiviral treatments as they become available, and the introduction and cessation of existing interventions via interim analyses. The first two interventions to be evaluated are molnupiravir (Lagevrio) and nirmatrelvir/ritonavir (Paxlovid). ELIGIBILITY CRITERIA community-dwelling within 5 days of onset of symptomatic COVID-19 (confirmed by PCR or lateral flow test), and either (1) aged 50 years and over, or (2) aged 18-49 years with qualifying comorbidities. Registration occurs via the trial website and by telephone. Recruitment occurs remotely through the central trial team, or in person through clinical sites. Participants are randomised to receive either usual care or a trial drug plus usual care. Outcomes are collected via a participant-completed daily electronic symptom diary for 28 days post randomisation. Participants and/or their Trial Partner are contacted by the research team after days 7, 14 and 28 if the diary is not completed, or if the participant is unable to access the diary. The primary efficacy endpoint is all-cause, non-elective hospitalisation and/or death within 28 days of randomisation. Multiple prespecified interim analyses allow interventions to be stopped for futility or superiority based on prespecified decision criteria. A prospective economic evaluation is embedded within the trial. ETHICS AND DISSEMINATION Ethical approval granted by South Central-Berkshire REC number: 21/SC/0393; IRAS project ID: 1004274. Results will be presented to policymakers and at conferences, and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER ISRCTN30448031; EudraCT number: 2021-005748-31.

Abstract
Background The effectiveness of repurposed treatments with supportive evidence for higher risk individuals with COVID-19 in the community is unknown. In the UK PRINCIPLE national platform trial we aimed to determine whether 're-purposed medicines' (hydroxychloroquine, azithromycin, doxycycline, colchicine, inhaled budesonide, and other interventions) reduced time to recovery and COVID-19 related hospitalisations/deaths among people at higher risk of COVID-19 complications in the community. We mainly report the findings for budesonide arm here. Methods Participants in this multicentre, open-label, multi-arm, adaptive platform randomised controlled trial were aged ≥65, or ≥50 years with comorbidities, and unwell ≤14 days with suspected COVID-19 in the community, and were randomised to usual care, usual care plus inhaled budesonide (800μg twice daily for 14 days), or usual care plus other interventions. The co-primary endpoints are time to first self-reported recovery, and hospitalisation/death related to COVID-19, within 28 days, analysed using Bayesian models. Trial registration: ISRCTN86534580. Funded by United Kingdom Research Innovation (MC_PC_19079). Findings The trial opened on April 2, 2020, with the first 4 intervention arms stopped on futility grounds. Randomisation to the budesonide arm occurred from November 27, 2020 until March 31, 2021, when the pre-specified time to recovery superiority criterion was met. The primary analysis model includes 2530 SARS-CoV-2 positive participants, randomised to budesonide (n=787), usual care (n=1069), and other treatments (n=674). Time to first self-reported recovery was shorter in the budesonide group versus usual care (hazard ratio 1·21 [95% credible interval 1·08 to 1·36], probability of superiority >O·999, estimated benefit 2·94 [95% credible interval 1·19 to 5·12] days). An estimated 6·8% COVID-19 related hospitalisations/deaths occurred in the budesonide group versus 8·8% in usual care (estimated absolute difference, 2·0% [95% credible interval -0.2% to 4.5%], probability of superiority 0.963). In the main secondary analysis of admissions using only concurrent controls, admissions occurred in 6.6% (3.8 to 10.1%) in the budesonide group versus 8.8% (95% CI 5.2 to 13.1%), with an absolute difference of 2.2% (0.0 to 4.9%) and a hazard ratio of 0.73 (0.53 to 1.00), meeting the pre-specified superiority probability of 0.975. Three serious adverse events occurred in the budesonide group and three in usual care.

Abstract
BACKGROUND Colchicine has been proposed as a COVID-19 treatment. AIM To determine whether colchicine reduces time to recovery and COVID-19-related admissions to hospital and/or deaths among people in the community. DESIGN AND SETTING Prospective, multicentre, open-label, multi-arm, randomised, controlled, adaptive platform trial (PRINCIPLE). METHOD Adults aged ≥65 years or ≥18 years with comorbidities or shortness of breath, and unwell for ≤14 days with suspected COVID-19 in the community, were randomised to usual care, usual care plus colchicine (500 µg daily for 14 days), or usual care plus other interventions. The co-primary endpoints were time to first self-reported recovery and admission to hospital/death related to COVID-19, within 28 days, analysed using Bayesian models. RESULTS The trial opened on 2 April 2020. Randomisation to colchicine started on 4 March 2021 and stopped on 26 May 2021 because the prespecified time to recovery futility criterion was met. The primary analysis model included 2755 participants who were SARS-CoV-2 positive, randomised to colchicine (n = 156), usual care (n = 1145), and other treatments (n = 1454). Time to first self-reported recovery was similar in the colchicine group compared with usual care with an estimated hazard ratio of 0.92 (95% credible interval (CrI) = 0.72 to 1.16) and an estimated increase of 1.4 days in median time to self-reported recovery for colchicine versus usual care. The probability of meaningful benefit in time to recovery was very low at 1.8%. COVID-19-related admissions to hospital/deaths were similar in the colchicine group versus usual care, with an estimated odds ratio of 0.76 (95% CrI = 0.28 to 1.89) and an estimated difference of -0.4% (95% CrI = -2.7 to 2.4). CONCLUSION Colchicine did not improve time to recovery in people at higher risk of complications with COVID-19 in the community.

Abstract
BACKGROUND A previous efficacy trial found benefit from inhaled budesonide for COVID-19 in patients not admitted to hospital, but effectiveness in high-risk individuals is unknown. We aimed to establish whether inhaled budesonide reduces time to recovery and COVID-19-related hospital admissions or deaths among people at high risk of complications in the community. METHODS PRINCIPLE is a multicentre, open-label, multi-arm, randomised, controlled, adaptive platform trial done remotely from a central trial site and at primary care centres in the UK. Eligible participants were aged 65 years or older or 50 years or older with comorbidities, and unwell for up to 14 days with suspected COVID-19 but not admitted to hospital. Participants were randomly assigned to usual care, usual care plus inhaled budesonide (800 μg twice daily for 14 days), or usual care plus other interventions, and followed up for 28 days. Participants were aware of group assignment. The coprimary endpoints are time to first self-reported recovery and hospital admission or death related to COVID-19, within 28 days, analysed using Bayesian models. The primary analysis population included all eligible SARS-CoV-2-positive participants randomly assigned to budesonide, usual care, and other interventions, from the start of the platform trial until the budesonide group was closed. This trial is registered at the ISRCTN registry (ISRCTN86534580) and is ongoing. FINDINGS The trial began enrolment on April 2, 2020, with randomisation to budesonide from Nov 27, 2020, until March 31, 2021, when the prespecified time to recovery superiority criterion was met. 4700 participants were randomly assigned to budesonide (n=1073), usual care alone (n=1988), or other treatments (n=1639). The primary analysis model includes 2530 SARS-CoV-2-positive participants, with 787 in the budesonide group, 1069 in the usual care group, and 974 receiving other treatments. There was a benefit in time to first self-reported recovery of an estimated 2·94 days (95% Bayesian credible interval [BCI] 1·19 to 5·12) in the budesonide group versus the usual care group (11·8 days [95% BCI 10·0 to 14·1] vs 14·7 days [12·3 to 18·0]; hazard ratio 1·21 [95% BCI 1·08 to 1·36]), with a probability of superiority greater than 0·999, meeting the prespecified superiority threshold of 0·99. For the hospital admission or death outcome, the estimated rate was 6·8% (95% BCI 4·1 to 10·2) in the budesonide group versus 8·8% (5·5 to 12·7) in the usual care group (estimated absolute difference 2·0% [95% BCI -0·2 to 4·5]; odds ratio 0·75 [95% BCI 0·55 to 1·03]), with a probability of superiority 0·963, below the prespecified superiority threshold of 0·975. Two participants in the budesonide group and four in the usual care group had serious adverse events (hospital admissions unrelated to COVID-19). INTERPRETATION Inhaled budesonide improves time to recovery, with a chance of also reducing hospital admissions or deaths (although our results did not meet the superiority threshold), in people with COVID-19 in the community who are at higher risk of complications.

Abstract
INTRODUCTION There is an urgent need to idenfy treatments for COVID-19 that reduce illness duration and hospital admission in those at higher risk of a longer illness course and complications. METHODS AND ANALYSIS The Platform Randomised trial of INterventions against COVID-19 In older peoPLE trial is an open-label, multiarm, prospective, adaptive platform, randomised clinical trial to evaluate potential treatments for COVID-19 in the community. A master protocol governs the addition of new interventions as they become available, as well as the inclusion and cessation of existing intervention arms via frequent interim analyses. The first three interventions are hydroxychloroquine, azithromycin and doxycycline. Eligible participants must be symptomatic in the community with possible or confirmed COVID-19 that started in the preceding 14 days and either (1) aged 65 years and over or (2) aged 50-64 years with comorbidities. Recruitment is through general practice, health service helplines, COVID-19 'hot hubs' and directly through the trial website. Participants are randomised to receive either usual care or a study drug plus usual care, and outcomes are collected via daily online symptom diary for 28 days from randomisation. The research team contacts participants and/or their study partner following days 7, 14 and 28 if the online diary is not completed. The trial has two coprimary endpoints: time to first self-report of feeling recovered from possible COVID-19 and hospital admission or death from possible COVID-19 infection, both within 28 days from randomisation. Prespecified interim analyses assess efficacy or futility of interventions and to modify randomisation probabilities that allocate more participants to interventions with better outcomes. ETHICS AND DISSEMINATION Ethical approval Ref: 20/SC/0158 South Central - Berkshire Research Ethics Committee; IRAS Project ID: 281958; EudraCT Number: 2020-001209-22.

Abstract
BACKGROUND Azithromycin, an antibiotic with potential antiviral and anti-inflammatory properties, has been used to treat COVID-19, but evidence from community randomised trials is lacking. We aimed to assess the effectiveness of azithromycin to treat suspected COVID-19 among people in the community who had an increased risk of complications. METHODS In this UK-based, primary care, open-label, multi-arm, adaptive platform randomised trial of interventions against COVID-19 in people at increased risk of an adverse clinical course (PRINCIPLE), we randomly assigned people aged 65 years and older, or 50 years and older with at least one comorbidity, who had been unwell for 14 days or less with suspected COVID-19, to usual care plus azithromycin 500 mg daily for three days, usual care plus other interventions, or usual care alone. The trial had two coprimary endpoints measured within 28 days from randomisation: time to first self-reported recovery, analysed using a Bayesian piecewise exponential, and hospital admission or death related to COVID-19, analysed using a Bayesian logistic regression model. Eligible participants with outcome data were included in the primary analysis, and those who received the allocated treatment were included in the safety analysis. The trial is registered with ISRCTN, ISRCTN86534580. FINDINGS The first participant was recruited to PRINCIPLE on April 2, 2020. The azithromycin group enrolled participants between May 22 and Nov 30, 2020, by which time 2265 participants had been randomly assigned, 540 to azithromycin plus usual care, 875 to usual care alone, and 850 to other interventions. 2120 (94%) of 2265 participants provided follow-up data and were included in the Bayesian primary analysis, 500 participants in the azithromycin plus usual care group, 823 in the usual care alone group, and 797 in other intervention groups. 402 (80%) of 500 participants in the azithromycin plus usual care group and 631 (77%) of 823 participants in the usual care alone group reported feeling recovered within 28 days. We found little evidence of a meaningful benefit in the azithromycin plus usual care group in time to first reported recovery versus usual care alone (hazard ratio 1·08, 95% Bayesian credibility interval [BCI] 0·95 to 1·23), equating to an estimated benefit in median time to first recovery of 0·94 days (95% BCI -0·56 to 2·43). The probability that there was a clinically meaningful benefit of at least 1·5 days in time to recovery was 0·23. 16 (3%) of 500 participants in the azithromycin plus usual care group and 28 (3%) of 823 participants in the usual care alone group were hospitalised (absolute benefit in percentage 0·3%, 95% BCI -1·7 to 2·2). There were no deaths in either study group. Safety outcomes were similar in both groups. Two (1%) of 455 participants in the azothromycin plus usual care group and four (1%) of 668 participants in the usual care alone group reported admission to hospital during the trial, not related to COVID-19. INTERPRETATION Our findings do not justify the routine use of azithromycin for reducing time to recovery or risk of hospitalisation for people with suspected COVID-19 in the community. These findings have important antibiotic stewardship implications during this pandemic, as inappropriate use of antibiotics leads to increased antimicrobial resistance, and there is evidence that azithromycin use increased during the pandemic in the UK.

Abstract
OBJECTIVES To determine the feasibility of conducting a randomised trial of the effectiveness of cranberry extract in reducing antibiotic use by women with symptoms of acute, uncomplicated urinary tract infection (UTI). DESIGN Open-label feasibility randomised parallel group trial. SETTING Four general practices in Oxfordshire. PARTICIPANTS Women aged 18 years and above presenting to general practice with symptoms of acute, uncomplicated UTI. INTERVENTIONS Women were randomly assigned using Research Electronic Data Capture in a 1:1:1 ratio to: (1) immediate antibiotics alone (n=15); (2) immediate antibiotics and immediate cranberry capsules for up to 7 days (n=15); or (3) immediate cranberry capsules and delayed antibiotics for self-initiation in case of non-improvement or worsening of symptoms (n=16). PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome measures were: rate of recruitment of participants; numbers lost to follow-up; proportion of electronic diaries completed by participants; and acceptability of the intervention and study procedures to participants and recruiters. Secondary outcomes included an exploration of differences in symptom burden and antibiotic use between groups. RESULTS Four general practitioner practices (100%) were opened and recruited participants between 1 July and 2 December 2019, with nine study participants recruited per month on average. 68.7% (46/67) of eligible participants were randomised (target 45) with a mean age of 48.4 years (SD 19.9, range 18-81). 89.1% (41/46) of diaries contained some participant entered data and 69.6% (32/46) were fully complete. Three participants (6.5%) were lost to follow-up and two (4.4%) withdrew. Of women randomly assigned to take antibiotics alone (controls), one-third of respondents reported consuming cranberry products (33.3%, 4/12). There were no serious adverse events. CONCLUSIONS It appears feasible to conduct a randomised trial of the use of cranberry extract in the treatment of acute, uncomplicated UTI in general practice.

Abstract
BACKGROUND The HIV protease inhibitor lopinavir, boosted with ritonavir, has been used off-label to treat COVID-19. We aimed to synthesize the clinical evidence for lopinavir/ritonavir as a treatment for COVID-19. METHODS We performed a rapid review by searching databases including PubMed, GoogleScholar, medRxiv, ClinicalTrials.gov and the Cochrane COVID-19 Study Register, for COVID-19 studies comparing outcomes between patients who did and did not receive lopinavir/ritonavir. The quality of evidence was assessed using the GRADE criteria. RESULTS We identified five completed randomized controlled trials (RCTs) and 14 retrospective cohort studies. Two large RCTs of 5,040 and 2,771 hospitalized adults with COVID-19 found no evidence that lopinavir/ritonavir influenced the primary outcome of mortality, or secondary outcomes including progression to mechanical ventilation or time to discharge. Results remained similar in all sub-group analyses including by age, gender, baseline ventilation and time since symptom onset. The three smaller RCTs (n=86-199) also found no evidence of a benefit in the primary outcomes of time to clinical improvement or time to viral clearance. The 14 observational studies included between 50 and 415 participants, and were limited by a lack of adjustment for potential confounding variables. The majority of these studies found no evidence that lopinavir/ritonavir was associated with improved mortality or other clinical outcomes, although results regarding viral clearance were mixed. CONCLUSIONS Good evidence from large clinical trials does not support using lopinavir/ritonavir to treat COVID-19 amongst hospitalized patients.

Abstract
BACKGROUND Consultations in primary care for symptoms of urinary tract infections (UTIs) are common and patients are frequently treated with antibiotics. Given increasing antimicrobial resistance, there has been interest in non-antibiotic treatment options for common infections. One such option is the use of cranberry extract to treat symptoms attributable to UTIs. METHODS A target of 45 women consulting in primary care, with symptoms suggestive of an uncomplicated UTI for whom the practitioner would normally prescribe antibiotics, will be randomised to receive one of three treatment approaches: (1) immediate prescription for antibiotics; (2) immediate prescription for antibiotics plus a 7-day course of cranberry capsules and (3) cranberry capsules plus a delayed prescription for antibiotics to be used in case their symptoms do not get better, or get worse. Follow-up will be by daily rating of symptoms and recording of treatments used for 2 weeks in an online symptom diary. Interviews will be conducted with around 10-15 study participants, as well as with around 10-15 women who have experienced a UTI but have not been approached to take part in the study. Both groups will be asked about their experience of having a UTI, their thoughts on non-antibiotic treatments for UTIs and their thoughts on, or experience of, the feasibility trial. The primary objective is to assess the feasibility of undertaking a full trial in primary care of the effectiveness of cranberry extract to reduce antibiotic use for symptoms of acute uncomplicated UTI. The secondary objective is to conduct a preliminary assessment of the extent to which cranberry might reduce antibiotic use and symptom burden. DISCUSSION This feasibility study with embedded interviews will inform the planning and sample size calculation of an adequately powered trial to definitively determine whether cranberry helps to alleviate the symptoms of acute uncomplicated UTIs in women and whether it can safely reduce antibiotic use.

Abstract
Objective To assess the cephalometric skeletal and soft-tissue of functional appliances in treated versus untreated Class II subjects in the long-term (primarily at the end of growth, secondarily at least 3 years after retention). Search methods Unrestricted electronic search of 24 databases and additional manual searches up to March 2018. Selection criteria Randomised and non-randomised controlled trials reporting on cephalometric skeletal and soft-tissue measurements of Class II patients (aged 16 years or under) treated with functional appliances, worn alone or in combination with multi-bracket therapy, compared to untreated Class II subjects. Data collection and analysis Mean differences (MDs) and 95% confidence intervals (95% CIs) were calculated with the random-effects model. Data were analysed at 2 primary time points (above 18 years of age, at the end of growth according to the Cervical Vertebral Maturation method) and a secondary time point (at least 3 years after retention). The risk of bias and quality of evidence were assessed according to the ROBINS tool and GRADE system, respectively. Results Eight non-randomised studies published in 12 papers were included. Functional appliances produced a significant improvement of the maxillo-mandibular relationship, at almost all time points (Wits appraisal at the end of growth, MD -3.52 mm, 95% CI -5.11 to -1.93, P < 0.0001). The greatest increase in mandibular length was recorded in patients aged 18 years and above (Co-Gn, MD 3.20 mm, 95% CI 1.32 to 5.08, P = 0.0009), although the improvement of the mandibular projection was negligible or not significant. The quality of evidence was ‘very low’ for most of the outcomes at both primary time points. Conclusions Functional appliances may be effective in correcting skeletal Class II malocclusion in the long-term, however the quality of the evidence was very low and the clinical significance was limited.

Abstract
AIM To critically appraise and evaluate the evidence from randomized clinical trials (RCTs) examining the effectiveness of oil pulling on oro dental hygiene. METHODS We conducted electronic searches in Medline, Embase, Amed, The Cochrane Library and Cinahl databases from inception to February 2015, and assessed reporting quality using the Cochrane risk of bias criteria. We included RCTs that compared oil pulling using conventional cooking oils with a control intervention. Our primary outcomes were measures of oro dental hygiene using validated scales. RESULTS Electronic searches yielded 26 eligible studies, of which five RCTs comprising a total of 160 participants were included. The studies varied in reporting quality, lasted between 10 and 45 days, and compared oil pulling with chlorhexidine, placebo or routine dental hygiene practice. Three studies reported no significant differences in post intervention plaque index scores between oil pulling and control groups (Chlorhexidine mouthwash +/- Placebo): p=0.28, 0.94, and 0.38, respectively. Two studies reported no significant difference in post-intervention modified gingival index score between oil pulling and Chlorhexidine mouthwash groups (p=0.32 and 0.64). CONCLUSION The limited evidence to date from clinical trials suggests that oil pulling may have beneficial effects on oro dental hygiene as seen for the short period of time investigated. Given that this is a potentially cost-effective intervention, this practice might be of particular benefit. Future clinical trials should be more rigorous and better reported.

Abstract
A cross sectional estimation of serum heat stable alkaline phosphatase (HSAP) levels in 145 women with uncomplicated pregnancies between 24-41 weeks gestation showed increasing levels with advancing gestation and a steep rise at about 34 weeks gestation from a mean level of 17.3 +/- 6.5 micrograms/ml to a mean level of 36.1 +/- 1.5 micrograms/ml (t = 7.4 p less than .001) at about 37 weeks gestation. Ninety-three point seven percent (93.7%) and 24.4% of women between 31-35 weeks gestation and 27-34 weeks gestation respectively had levels equal to or exceeding 20 micrograms/ml. It is postulated that serum HSAP represent stages of fetal maturity rather than gestational age per se and that there is a possible relationship between serum HSAP and amniotic fluid lecithin viewed against a background of a similar rise of amniotic fluid lecithin levels at about 33 weeks gestation and the common role of steroid receptor sites in the formation of both HSAP and Lecithin.
