Phase 1 trials are used to determine drug toxicity. All that reault really says is that the new drug won't itself kill the patients. It still needs to be compared relative to the standard of care in larger phase 2 and 3 trials.

However, the article also describes patients in the trial having positive effects. Yes, it's not an efficacy trial, but if it was specifically used on patients who have exhausted all other clinical options, there were no significant adverse side-effects, and there were beneficial effects for some substantial number of patients, that sounds pretty hopeful to me. Of course it's possible issues will still be discovered, but this is a long way from a top-of-funnel lab result.
