Does Remdesivir cause bone marrow suppression?
From Off-Target In Vitro Profiling Demonstrates that Remdesivir Is a Highly Selective Antiviral Agent:

Overall, the cellular and biochemical assays demonstrated a low potential for RDV to elicit off-target toxicity, including mitochondria-specific toxicity, consistent with the reported clinical safety profile.

This isn't a very complete answer, but the wikipedia article doesn't go into detail or link references explaining the mechanism by which nucleoside analogues suppress bone marrow function. So I can't say if the assay results in my link rule out a suppression effect by remdesivir
