Not sure what a "BA" Breach is, but deliberately delaying clinical trials (a tough thing to prove) would be a Material Breach of "(c) failure to use Commercially Reasonable Efforts pursuant to Section 4.2(a)".
But since you thought to copy and paste it, this could also be relevant:
"ALFASIGMA shall not be liable for any failure to perform, or be considered in breach of, its obligations under this Agreement (other than obligations to make payments of money) to the extent such performance has been delayed, interfered with or prevented by an event of Force Majeure."
I think it's generally accepted that this pandemic meets the definition of "force majeure", but AS has been able to conduct certain business, including beginning and conducting clinical trials, during the period since the WHO declared the outbreak a pandemic back in March.
Sounds like AS might find it difficult to escape the deal via the force majeure language if they were so inclined.
