MIKADO: a multicentre, open‐label pilot study to evaluate the antiretroviral activity and safety of saquinavir with stavudine and zalcitabine
Bibliographic record
Abstract
BACKGROUND: Since eradication of HIV is unlikely, long-term management of the disease necessitates careful evaluation of the combinations of currently available drugs to determine the most potent and useful rational sequencing of regimens. OBJECTIVE: To determine the antiretroviral efficacy and tolerability of saquinavir soft gelatin capsule (SQV-SGC) plus zalcitabine (ddC) and stavudine (d4T), as first-line treatment in HIV-infected patients. DESIGN: Multicentre, open-label, non-comparative study. PATIENTS AND METHODS: Thirty-five asymptomatic, HIV-infected adults with no prior antiretroviral treatment, a CD4 count > or =250 cells/microL and baseline > or = 5000 HIV RNA copies/mL were included in the study. Patients received SQV-SGC 1200 mg three times a day (tid), ddC 0.75 mg tid and d4T 30 or 40 mg twice a day (bid) for 24 weeks. Plasma HIV RNA, CD4 and CD8 cell counts, HIV reverse transcriptase and protease resistance genotypes, SQV plasma concentration and tolerability were evaluated. RESULTS: At baseline, median HIV RNA (interquartile range) was 4.99 (4.81-5.48) log10 copies/mL, and median CD4 count was 370 (318-504) cells/microL (n = 35). At week 24, the median decrease in HIV RNA was 3.05 (2.19-3.68) log10 copies/mL. A viral load below the level of quantification (200 copies/mL and 20 copies/mL) was achieved in 63% and 34% of patients, respectively (intent-to-treat analysis). The only mutations detected were L90M substitutions in two patients. At week 24, the median CD4 count increased (P < 0.0001), and CD8 cell counts decreased (P < 0.0001), relative to baseline. In total, there were five cases of peripheral neuropathy (14%). Mean triglyceride and cholesterol levels remained within normal ranges. CONCLUSIONS: Triple therapy with SQV-SGC plus ddC and d4T is a reasonably well tolerated regimen that markedly and rapidly reduces viral load with immunological improvement. This combination is an effective additional therapeutic option, with an efficacy that compares favourably to other triple regimens used in HIV treatment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
