Several of today's healthcare winners are extending their gains meaningfully as the sessions wears on.

InVivo (NVIV +56%) has skyrocketed since updating investors on its degradable polymer scaffold program earlier in the day.

Ligand Pharmaceuticals (LGND +8.5%) has more than doubled its early gains on the strength of an upgrade at Cantor, where analyst Irina Rivkind is now "more comfortable with the growth prospects for the business based primarily on management's higher guidance on material sales and milestones."

Biostar Pharmaceuticals (BSPM +16.5%) is up double-digits after posting modest premarket gains, bringing the two-day rally to ~92%.
