My thoughts are these:
1) It’s exciting to hear of a drug that has been shown to slow progression by 27% with no adverse side effects.
2) Phase 3 began in May, 2019, but, according to ClinicalTrials.gov, will not reach completion until 2024. Mastinib was shown to slow progression by 25% at least two years ago:

3) Perhaps someone more knowledgeable about trials than I am might be willing to explain why trials like these must take as long as seven years.
4) I would be interested to know if any forum members may have considered the Right to Try Act in order to obtain access to a promising drug before it’s been approved by the FDA: https://www.fda.gov/patients/learn-about-expanded-access-and-other-treatment-options/right-try
Thank you.
