It would have been at the day 38 point on figure 2 in the TAPER trial, but difference is the TAPER trial had 2 weeks of extra duration in the intervention arm, in Fidax vs Vanc trial it was 10 days for both arms.

15% vs 25% over 4 weeks - not long but long enough to have seen the effect in the trial above. Would be nice to have longer follow up data, but I don't think we are going to get it.

Also tapered vanc only seems to be briefly better at that one timepoint and overall recurrence rates were the same, whereas fidaxomicin was lower recurrence rate overall compared to vanc.

Can't see results on that link, but I don't think it is safe reasoning to say A better than B in trial 1, B same to C in trial 2, therefore A better than C. Could be low power in trial 2, for instance, and network analyses needed to address this.

In head to head fidaxomycin vs vancomycin, fidaxomycin had lower recurrence rate - e.g. www.nejm.org/doi/full/10.... - but I suppose not clear if this is still true in a post-027 world.

Figure 2 makes it look like the extended vancomycin just delays the recurrence by a few weeks. Which doesn't seem all that helpful.

🧬Curious about the state of malaria drug resistance in Kenya?
Our study shows first-line malaria treatments remain effective but early resistance signals highlight need for routine molecular surveillance, monitoring emerging markers & data-informed treatment policy.

4/4 A key learning from this evaluation is that bioinformatic criteria are key, need to be set prospectively, and that both sensitivity and specificity depend on these decisions.

3/ 4Then there is barcode crossover because we can't afford to burn a whole flow cell on a single sample (cost entirely prohibitive if we do).

2/4 Reflecting honestly on this, metagenomics at scale is a tough proposition when evaluated like this. Targeted PCR is highly sensitive, sequencing is expensive and host DNA contamination makes it more so.

1/4 Thrilled to get this metagenomic diagnostic study over the line. We have an in house method that targets RNA viruses in respiratory samples, and evaluated this against 344 prospective samples tested by multiplex PCR.

Yes, I think fair enough to do these studies when limited data on how well it worked in different populations, but hard to say now that we have equipoise about LEN compared to an experimental vaccine.

25.02.2026 21:07 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

The ethics seem difficult where LEN might be unavailable, but for similar costs as enrolling a patient and giving an experimental vaccine, one could provide LEN.

Any discussion on how difficult it might be to test preventive vaccines when lenacapavir is available - i.e. seems difficult to follow up a high risk cohort ethically without providing this?
