True, Novartis makes it, but looks as a license deal with GSK under Brand name Hycamtin. See links below. Could be wrong, no matter...
Also, looks like Novartis just terminated a phase 1b/2 small cell lung cancer trial in August, 2021, so perhaps a great time to partner. There are generics, yet perhaps a combo therapy with a major player could warrant several years of new patent protection for each and a nice partnership agreement for Algernon.
