 expect lower resistance relative to other antifungal drug classes to be a major factor in the commercialization of ibrexafungerp, rapid development of such resistance or development of cross resistance with echinocandins would have a major adverse impact on the acceptability and sales of ibrexafungerp.

Our approved product and product candidates may have undesirable side effects that may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market or otherwise limit their sales.

It is impossible to predict when or if ibrexafungerp for indications other than VVC, RVVC or any other product candidate we may seek to develop will prove effective or safe, or whether we or GSK will receive marketing approval for ibrexafungerp for the treatment of indications other than VVC, RVVC, or whether we will receive marketing approval for any other products we may seek to develop. Unforeseen side effects from any product candidates could arise either during clinical development or, if approved, after the product has been marketed. The most commonly reported adverse events after oral administration of ibrexafungerp have been gastrointestinal (GI) events (i.e., nausea, diarrhea, vomiting).  The gastrointestinal events reported have typically been transient (i.e., short duration), mild or moderate and not leading to discontinuation.  The most commonly reported adverse events after IV administration of ibrexafungerp have been local reactions at the site of infusion.  During our Phase 1 IV program in healthy volunteers, aimed to expand the safety margin that would allow greater flexibility of dosing options in patients, we observed three mild-to-moderate thrombotic events in healthy volunteers receiving the IV formulation of ibrexafungerp at the highest doses and highest concentrations.  These events were reported to FDA as 15-day alert reports because they were unexpected and required anticoagulant therapy.  The potential contribution of the IV formulation of ibrexafungerp to these events cannot be ruled out even though rates of thrombotic events due to intravenous catheters reported in the literature are comparable to those observed in the Phase 1 study.  

Serious adverse events (SAEs) are common when conducting clinical trials in a seriously ill population such as patients experiencing invasive candidiasis. Several SAEs have been reported in our clinical trials but only four of the events have been deemed by the investigator to be potentially related to ibrexafungerp, although other contributing factors could not be ruled out.
