What IR gave you was a stall.Your take is correct. Insmed will not partner imho until a more positive development arises,more ALS data ,trial data etc. Many of these "longs in love" should assess the risks of owning Insmed . It is a very risky stock.
IR brushed you off because there is little to tell. I stand on the sidelines and will watch till something positive happens . I think the stock is dead money until then
