Cap-dependent endonuclease inhibitor, inhibits the first proliferation step after viral entry into the cell
Weekly GP consultations for flu-like illness in England in 2019 ranged from 13 to 23 per 100,000 (~300 per 100,000/year), but were lower than the previous year. [17] In addition, ~17,500 prescriptions for antivirals were dispensed in primary care in England in 2019 (~30 per 100,000 people), presumably for people at risk of serious complications. [18]

Trial or other data
Jul 20Japanese RCT (752 household contacts of 545 index patients) found single-dose baloxavir (BL) showed efficacy in preventing influenza in household contacts of patients with influenza (clinical influenza developed in 1.9% on BL vs. 13.6% placebo; risk ratio, 0.14; 95% CI, 0.06-0.30;p<0.001) [20].
Jun 20PIII CAPSTONE-2 trial (n=2,184) found single-dose baloxavir had superior efficacy to placebo (73.2h vs. 102.3h; difference 29.1h [95% CI 14.6 to 42.8], p<0.0001) and similar efficacy to oseltamivir (81.0h; difference from baloxavir 7.7h) in time to improvement of influenza symptoms [13].
Oct 18New late-stage data released from CAPSTONE-2 trial. Baloxavir marboxil significantly reduced the median time to symptom improvement in influenza type A/H3N2 and type B to 75.4 hours and 74.6 hours, respectively, versus 100.4 hours and 100.6 hours for placebo (p<0.05). Numerically there was a shorter median time to improvement of influenza symptoms with baloxavir vs. oseltamivir (73.2 vs. 81 hours) but this was not statistically significant. This outcome mirrors a similar one from the CAPSTONE-1 study in uncomplicated influenza, where the time to alleviation of symptoms was similar between the two drugs [5,6].
Jul 18In the published PIII CAPSTONE I study (n=1436), the time to alleviation of influenza symptoms (TTAS) was shorter with a single oral baloxavir dose vs. placebo (median TTAS: 53.7 hours vs. 80.2 hours, P < 0.0001). Faster resolution of fever vs. placebo was also observed (24.5 vs. 42.0 hours, p < 0.0001) with baloxavir vs. placebo. Duration of symptoms was similar for baloxavir dose and oseltamivir (TTAS 53.5 hours vs. 53.8 hours; p=0.76) as was fever reduction (median time 24.4 hours versus 24.0 hours; p=0.92). Median time to cessation of viral shedding (determined from nasal/throat swabs) was 24 hours with baloxavir vs. 72 hours with oseltamivir (P < 0.0001) and 96 hours for placebo (P < 0.0001). [9,10]
Sep 18: CAPSTONE-1 data and editorial on influenza treatment published the the NEJM. [9,10]
Sep 17: Data from PIII CAPSTONE-1 study presented at conference. Study (n=1436) in patients with influenza reported similar time to alleviation of symptoms with S-033188 vs oseltamivir; 53.7 hours vs 80.2 hours (p<0.0001) [4].
Sep 17CAPSTONE-2 (NCT02949011) is currently recruiting in US and UK. Primary objective of this study is to evaluate efficacy of a single, oral dose of S-033188 compared with placebo by measuring time to improvement of influenza symptoms in patients with influenza at high risk of influenza complications presenting within 48 hours of symptom onset. Estimated primary completion date is Jul 18 [3].

Roche announced that PIII BLOCKSTONE study showed preventive treatment with )(baloxavir marboxil) after exposure to an infected household member significantly reduced the risk of developing flu by 86% versus placebo. The results show just 1.9% of treated household members had flu compared with 13.6% in the placebo-treated group (p<0.0001) [6].

Sep 19In the PIII MINISTONE-2 study time to alleviation of influenza signs and symptoms of baloxavir was comparable to oseltamivir (median time of 138 hours vs 150 hours). Baloxavir marboxil reduced the length of time that the influenza virus continued to be released from the body by >2 days vs. oseltamivir (viral shedding; median time of 24.2 hours vs 75.8 hours, respectively. With baloxavir,46.1% experienced >1 adverse effect vs. 53.4% with oseltamivir.[4]
