14.2 Adult Patients with Prior Antiretroviral Therapy
Study 888: KALETRA Capsules twice daily + nevirapine + NRTIs compared to investigator-selected protease inhibitor(s) + nevirapine + NRTIs
Study 888 was a randomized, open-label, multicenter trial comparing treatment with KALETRA capsules (400/100 mg twice daily) plus nevirapine and nucleoside reverse transcriptase inhibitors versus investigator-selected protease inhibitor(s) plus nevirapine and nucleoside reverse transcriptase inhibitors in 288 single protease inhibitor-experienced, non-nucleoside reverse transcriptase inhibitor (NNRTI)-naïve patients. Patients had a mean age of 40 years (range: 18 to 74), 68% were Caucasian, and 86% were male. Mean baseline CD4+ cell count was 322 cells/mm 3 (range: 10 to 1059 cells/mm 3) and mean baseline plasma HIV-1 RNA was 4.1 log 10 copies/mL (range: 2.6 to 6.0 log 10 copies/mL).
Treatment response and outcomes of randomized treatment through Week 48 are presented in Table 24.
| Outcome | KALETRA + nevirapine + NRTIs (n = 148) | Investigator-Selected Protease Inhibitor(s) + nevirapine + NRTIs (n = 140) |
| Responder 1 | 57% | 33% |
| Virologic failure 2 Rebound Never suppressed through Week 48 | 24% 11% 13% | 41% 19% 23% |
| Death | 1% | 2% |
| Discontinued due to adverse events | 5% | 11% |
| Discontinued for other reasons 3 | 14% | 13% |
| 1 Patients achieved and maintained confirmed HIV-1 RNA < 400 copies/mL through Week 48. 2 Includes confirmed viral rebound and failure to achieve confirmed < 400 copies/mL through Week 48. 3 Includes lost to follow-up, patient’s withdrawal, non-compliance, protocol violation and other reasons. | ||
Through 48 weeks of therapy, there was a statistically significantly higher proportion of patients in the KALETRA arm compared to the investigator-selected protease inhibitor(s) arm with HIV-1 RNA < 400 copies/mL (57% vs. 33%, respectively).
Through 48 weeks of therapy, the mean increase from baseline in CD4+ cell count was 111 cells/mm 3 for the KALETRA arm and 112 cells/mm 3 for the investigator-selected protease inhibitor(s) arm.
Study 802: KALETRA Tablets 800/200 mg Once Daily Versus 400/100 mg Twice Daily when Co-administered with Nucleoside/Nucleotide Reverse Transcriptase Inhibitors in Antiretroviral-Experienced, HIV-1 Infected Subjects
M06-802 was a randomized open-label study comparing the safety, tolerability, and antiviral activity of once daily and twice daily dosing of KALETRA tablets in 599 subjects with detectable viral loads while receiving their current antiviral therapy. Of the enrolled subjects, 55% on both treatment arms had not been previously treated with a protease inhibitor and 81 – 88% had received prior NNRTIs as part of their anti-HIV treatment regimen. Patients were randomized in a 1:1 ratio to receive either KALETRA 800/200 mg once daily (n = 300) or KALETRA 400/100 mg twice daily (n = 299). Patients were administered at least two nucleoside/nucleotide reverse transcriptase inhibitors selected by the investigator. Mean age of patients enrolled was 41 years (range: 21 to 73); 51% were Caucasian, and 66% were male. Mean baseline CD4+ cell count was 254 cells/mm 3 (range: 4 to 952 cells/mm 3) and mean baseline plasma HIV-1 RNA was 4.3 log 10 copies/mL (range: 1.7 to 6.6 log 10 copies/mL).
Treatment response and outcomes of randomized treatment through Week 48 are presented in Table 25.
| Outcome | KALETRA Once Daily + NRTIs (n = 300) | KALETRA Twice Daily + NRTIs (n = 299) |
| Virologic Success (HIV-1 RNA <50 copies/mL) | 57% | 54% |
| Virologic failure 1 | 22% | 24% |
| No virologic data in Week 48 window | ||
| Discontinued study due to adverse event or death 2 | 5% | 7% |
| Discontinued study for other reasons 3 | 13% | 12% |
| Missing data during window but on study | 3% | 3% |
| 1 Includes patients who discontinued prior to Week 48 for lack or loss of efficacy and patients with HIV-1 RNA ≥ 50 copies/mL at Week 48. 2 Includes patients who discontinued due to adverse events or death at any time from Day 1 through Week 48 if this resulted in no virologic data on treatment at Week 48. 3 Includes withdrawal of consent, loss to follow-up, non-compliance, protocol violation and other reasons. | ||
Through 48 weeks of treatment, the mean change from baseline for CD4 + cell count was 135 cells/mm 3 for the once daily group and 122 cells/mm 3 for the twice daily group.
14.3 Other Studies Supporting Approval in Adult Patients
Study 720: KALETRA twice daily + stavudine + lamivudine
Study 765: KALETRA twice daily + nevirapine + NRTIs
Study 720 (patients without prior antiretroviral therapy) and study 765 (patients with prior protease inhibitor therapy) were randomized, blinded, multi-center trials evaluating treatment with KALETRA at up to three dose levels (200/100 mg twice daily [720 only], 400/100 mg twice daily, and 400/200 mg twice daily). In Study 720, all patients switched to 400/100 mg twice daily between Weeks 48-72. Patients in study 720 had a mean age of 35 years, 70% were Caucasian, and 96% were male, while patients in study 765 had a mean age of 40 years, 73% were Caucasian, and 90% were male. Mean (range) baseline CD4+ cell counts for patients in study 720 and study 765 were 338 (3-918) and 372 (72-807) cells/mm 3 , respectively. Mean (range) baseline plasma HIV-1 RNA levels for patients in study 720 and study 765 were 4.9 (3.3 to 6.3) and 4.0 (2.9 to 5.8) log 10 copies/mL, respectively.
Through 360 weeks of treatment in study 720, the proportion of patients with HIV-1 RNA < 400 (< 50) copies/mL was 61% (59%) [n = 100]. Among patients completing 360 weeks of treatment with CD4+ cell count measurements [n=60], the mean (median) increase in CD4+ cell count was 501 (457) cells/mm 3. Thirty-nine patients (39%) discontinued the study, including 13 (13%) discontinuations due to adverse reactions and 1 (1%) death.
Through 144 weeks of treatment in study 765, the proportion of patients with HIV-1 RNA < 400 (< 50) copies/mL was 54% (50%) [n = 70], and the corresponding mean increase in CD4+ cell count was 212 cells/mm 3. Twenty-seven patients (39%) discontinued the study, including 5 (7%) discontinuations secondary to adverse reactions and 2 (3%) deaths.
