Single-dose high-dose liposomal amphotericin B combination therapy,
does it really help with Noninferior 10-week all-cause mortality in HIV-associated cryptococcal meningitis?
research showsThe grade is B with 72 points. Ten-week all-cause mortality was 24.8% (101/407) with the single high-dose liposomal amphotericin B regimen and 28.7% (117/407) with standard amphotericin B deoxycholate, an absolute difference of -3.9 points. The upper one-sided 95% confidence limit was +1.2 points, within the prespecified +10-point noninferiority margin (P<0.001).
ads claimIt is supported to say that the single-dose AmBisome combination was noninferior for 10-week mortality. It is incorrect to say that one infusion completes treatment or that it significantly lowered mortality. Fourteen days of flucytosine and fluconazole and subsequent antifungal therapy were still required.
Useful facts when choosing a product
- The regimen used one 10 mg/kg intravenous AmBisome dose plus 14 days of flucytosine and fluconazole.
- Gilead Sciences donated AmBisome; investigators reported no company role in design, analysis, or manuscript preparation.
- This is hospital-based induction therapy for severe cryptococcal meningitis and requires specialist monitoring.
What the research actually shows
The trial randomized 844 adults with HIV-associated cryptococcal meningitis in five African countries and analyzed 814 in the prespecified population. The paper stated, "the trial was powered to show noninferiority at a 10-percentage-point margin." Mortality was 24.8% versus 28.7%, difference -3.9 points, upper limit +1.2 points. Complete-case and per-protocol analyses agreed.
Why this is classified as B (72)
This was a large randomized trial of actual 10-week mortality, and the result met the prespecified +10-point noninferiority margin. Lack of independent replication, the noninferiority design, and manufacturer provision of AmBisome give B with 72 points.
Counterpoint. The trial used specialist hospitals with access to combination antifungals and monitoring. The result cannot automatically be transferred to settings without flucytosine, inpatient support, or toxicity monitoring.

| Replication | R1 | Single confirmatory trial |
| Independence | I1 | Mixed funding sources |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (B).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Noninferiority for 10-week all-cause mortality | B | The +1.2-point upper limit was within the prespecified +10-point margin. |
| Reduction in severe adverse events | B | Grade 3 or 4 events were 50.0% versus 62.3%. |
