T303 |
0-281 |
Sentence |
denotes |
Several antiviral agents have demonstrated in vitro activity against SARS-CoV-2 or other coronaviruses, but currently there are no approved antiviral agents for coronavirus-related diseases, and there are still no favourable efficacy results from RCT available at the present time. |
T304 |
282-430 |
Sentence |
denotes |
Lopinavir is a protease inhibitor used for the treatment of HIV patients, administered in combination with ritonavir to improve its serum half-life. |
T305 |
431-732 |
Sentence |
denotes |
On the basis of its activity against SARS-CoV-1 and/or Middle East respiratory syndrome (MERS)-CoV observed in in vitro and animal studies [[19], [20], [21]], lopinavir/ritonavir (LPV/RTV) was compared to supportive care alone for the treatment of COVID-19 patients in an open-label RCT in China [22]. |
T306 |
733-981 |
Sentence |
denotes |
The primary time-to-event endpoint was clinical improvement from randomization (defined as a composite of discharge from the hospital or improvement of two points on a seven-category ordinal scale, ranging from no need of hospitalization to death). |

982-1085 |
Sentence |
denotes |

T308 |
1086-1283 |
Sentence |
denotes |
No differences were observed in the intent-to-treat population with regard to clinical improvement (hazard ratio 1.24 with standard of care as reference, 95% confidence interval (CI) 0.90 to 1.72). |
T309 |
1284-1552 |
Sentence |
denotes |
In addition, no associations were observed with regard to 28-day mortality, although a smaller number of deaths were registered in the LPV/RTV arm (19.2% vs. 25.0% in investigational and comparator arms, respectively; percentage difference −5.8%, 95% CI −17.3 to 5.7). |
T310 |
1553-2199 |
Sentence |
denotes |
Although some important considerations preclude a definite judgement on the possible efficacy of LPV/RTV (e.g. some major limitations are the open-label nature of the trial and the fact that LPV/RTV was initiated late with respect to the onset of symptoms; see question 7), especially in the case of early therapy initiation, the results of this RCT provide evidence currently discouraging the use of LPV/RTV (or of other protease inhibitors such as darunavir) in COVID-19 patients (also considering the potential side effects; Table 3 ), unless favourable results from other ongoing RCT in specific subgroups of patients are available (Table 2). |
T311 |
2200-2414 |

denotes |
Furthermore, harmful drug interactions of antivirals with other drugs (such as hydroxychloroquine) cannot be excluded a priori because there are currently no large clinical data about the use of these combinations. |
