What is Rivfloza?
From the FDA label:RIVFLOZA injection contains nedosiran, a double-stranded small interfering RNA (siRNA) with four covalently attached N -acetyl-D-galactosamine (GalNAc) residues. Nedosiran targets lactate dehydrogenase A (LDHA) in hepatocytes via GalNAc-mediated delivery. The structural formula of the nedosiran sodium drug substance is presented below: The molecular formula of nedosiran sodium is C 662 H 808 F 19 N 231 O 413 P 57 S 6 Na 57 with a molecular weight of 22,238 Da. Nedosiran sodium is freely soluble in water. RIVFLOZA Pre-filled Syringe is supplied as a clear, sterile, preservative-free, colorless‑to‑yellow solution for subcutaneous injection containing either the equivalent of 160 mg (present as 170 mg nedosiran sodium salt) nedosiran in 1 mL or the equivalent of 128 mg (present as 136 mg nedosiran sodium salt) nedosiran in 0.8 mL of water for injection and sodium hydroxide and/or hydrochloric acid to adjust the pH to ~7.2. RIVFLOZA vial is supplied as a clear, sterile, preservative-free, colorless-to-yellow solution for subcutaneous injection containing the equivalent of 80 mg (present as 85 mg nedosiran sodium salt) nedosiran in 0.5 mL of water for injection and sodium hydroxide and/or hydrochloric acid to adjust the pH to ~7.2. structural_formula

Side effects
Most common adverse reactions (reported in ≥20% of patients) are injection site reactions. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Novo Nordisk Inc. at 1-844-906-5099 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of RIVFLOZA has been evaluated in one placebo-controlled clinical trial (PHYOX2) and one open-label extension study (PHYOX3). Across these studies, 29 adults and 12 children with PH1 have been treated with RIVFLOZA. Patients with PH1 in these studies ranged in age from 9 to 46 years at first dose. The median duration of exposure was approximately 15 months (range 1-29 months). Overall, 38 patients with PH1 were treated for at least 6 months, 24 patients for at least 12 months, and 16 patients for at least 18 months. In the randomized, placebo-controlled, double-blind PHYOX2 trial in pediatric and adult patients 9 to 46 years of age, 18 patients with PH1 received RIVFLOZA and 11 patients received placebo. Of the 18 patients treated with RIVFLOZA, 17 patients received ≥5 months of active treatment. The most common adverse reactions were injection…
