Read moreEmergency use of Pandovir 5 mg/ml for treatment of suspected or laboratory confirmed Corona Virus Disease 2019 (COVID-19). Severe disease is defined as patients with an oxygen saturation (Sp02) <94% on room air or requiring supplemental oxygen or requiring mechanical ventilation or requiring extracorporeal membrane oxygenation (ECMO). Specifically, Pandovir 5 mg/ml is only authorized for hospitalized adult and pediatric patients for whom use of an intravenous agent is clinically appropriate.

Anti-viral drugs

Pandovir 5 mg/ml is a nucleoside analog that is expected to inhibit the action of RNA polymerase. By incorporating into RNA, additional nucleotides cannot be added, terminating RNA transcription. Viruses with mutations in RNA polymerase to develop partial resistance to Pandovir 5 mg/ml have been shown to be less infective.

The FDA Emergency Use Authorization suggests a loading dose of 200 mg once daily in patients ≥ 40 kg or 5 mg/kg once daily in patients 3.5 kg to less than 40 kg, followed by a maintenance dose of 100 mg once daily in patients ≥ 40 kg or 2.5 mg/kg once daily in patients 3.5 kg to less than 40 kg. Patients not needing invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO) should be treated for 5 days (including the loading dose on day 1), up to 10 days if they do not show improvement. Patients requiring invasive mechanical ventilation or ECMO should be treated for 10 days.Clinical trials used a regimen of 200mg once daily on the first day, followed by 100mg once daily for another 9 days. Early data suggests that some patients may benefit from only 5 days of treatment.Pandovir 5 mg/ml was originally investigated as a treatment for Ebola virus, but has potential to treat a variety of RNA viruses. Its activity against the coronavirus (CoV) family of viruses, such as SARS-CoV and MERS-CoV, was described in 2017, and it is also being investigated as a potential treatment for SARS-CoV-2 infections.

General Information- Adult and pediatric patients (>28 days and old) must have an eGFR determined and full-term neonates (≥7 days to ≤28 days old) must have serum creatinine determined before dosing of Pandovir 5 mg/ml. Hepatic laboratory testing should be performed in all patients prior to starting Pandovir 5 mg/ml and daily while receiving Pandovir 5 mg/ml. Pandovir 5 mg/ml should be administered via intravenous infusion only. Do not administer as intramuscular injection. Adult Patients- The recommended dosage in adults requiring invasive mechanical ventilation and/or ECMO is a single loading dose of Pandovir 5 mg/ml 200 mg on day 1 followed by once daily maintenance dose of Pandovir 5 mg/ml 100 mg for 9 days. The recommended dose in adults not requiring invasive mechanical ventilation and/or ECMO is a single dose of Pandovir 5 mg/ml 200 mg on day 1 followed by once daily maintenance dose of Pandovir 5 mg/ml 100 mg for 4 days. If a patient dose not demonstrate clinical improvement, treatment may be extended for up to 5 additional days (i.e. up to a total of 10 days) Pandovir 5 mg/ml is to be administered via intravenous infusion in a total volume of up to 250 ml 0.9% saline over 30 to 120 minutes. Pediatric Patients- The recommended pediatric dose for pediatric patients weighing between 3.5 kg <40 kg should be calculated using the mg/kg dose according to the patient’s weight. For pediatric patients with body weight between 3.5 kg <40 kg use Pandovir 5 mg/ml for injection 100 mg lyophilized powder only. Administer a body weight-based dosing regimen of one loading dose of Pandovir 5 mg/ml 5 mg/kg IV (infused over 30 to 120 minutes) on day 1 followed by Pandovir 5 mg/ml 2.5 mg/kg IV (infused over 30 to 120 minutes) once daily for 9 days (for pediatric patients requiring invasive mechanical ventilation and/or ECMO, days 2 through 5). If a patient dose not demonstrate clinical improvement, treatment may be extended for up to 5 additional days (i.e. up to a total of 10 days) For pediatric patients with body weight ≥40 kg requiring invasive mechanical ventilation and/or ECMO, the adult dosage regimen of one loading dose of Pandovir 5 mg/ml 200 mg IV (infused over 30 to 120 minutes) on day 1 followed by Pandovir 5 mg/ml 100 mg IV (infused over 30 to 120 minutes) once daily for 9 days will be administered. For pediatric patients with body weight ≥40 kg requiring invasive mechanical ventilation and/or ECMO, the adult dosage regimen of one loading dose of Pandovir 5 mg/ml 200 mg IV (infused over 30 to 120 minutes) on day 1 followed by Pandovir 5 mg/ml 100 mg IV (infused over 30 to 120 minutes) once daily for 4 days (days 2 through 5) will be administered. If a patient does not demonstrate clinical improvement, treatment may be extended for up to 5 additional days (i.e. up to a total of 10 days).

Anti-viral drugs

Pandovir 5 mg/ml is a preparation of Pandovir 5 mg/ml. It is an adenosine nucleotide prodrug that distributes into cells where it is metabolized to form the pharmacologically active nucleoside triphosphate metabolite. Metabolism of Pandovir 5 mg/ml to Pandovir 5 mg/ml Triphosphate has been demonstrated in multiple cell types. Pandovir 5 mg/ml Triphosphate act as an analogue of adenosine triphosphate (ATP) and competes with the natural ATP substrate for incorporation into nascent RNA chains by the SARS-CoV-2 RNA-dependent RNA polymerase, which results in delayed chain termination during replication of the viral RNA. Pandovir 5 mg/ml triphosphate is a weak inhibitor of mammalian DNA and RNA polymerase with low potential for mitochondrial toxicity.

No adequate and well controlled studies of Pandovir 5 mg/ml use in pregnant women have been conducted. Pandovir 5 mg/ml should be used in pregnancy only if the potential benefit justifies the potential risk for the mother fetus. There is no information regarding the presence of Pandovir 5 mg/ml in human milk, the effects on the breastfeed infants, or the effects on milk production. Because of the potential for viral transmission of SARS-CoV-2 negative infants and adverse reactions from the drug in breastfeeding infants, the development and health benefits of breastfeeding should be considered along with the mother's clinical need for Pandovir 5 mg/ml and any potential adverse effects on the breastfed child from Pandovir 5 mg/ml or from the underlying maternal condition.
