Wikipedia gives a 2% pregnancy rate for condoms within one year with perfect use which is much worse than 0.3%.
We only have the numbers for the lab environment with I assume perfect use for this new drug, so we can only compare perfect use.

The only reason for a properly used condom to not work would be a manufacturing defect, which should be extremely rare, certainly not 2%, that's plainly ridiculous and immediately disqualifies any study that claims so.
