I'm covering it here as well to join it up with the many previous posts on this topic.

Some good news is that the results of the Phase 1 trial show safety, and possible efficacy.

Some bad news is that no plans were mentioned for a Phase 2 trial, only that "Patients will continue to be evaluated every six months for another five years in the study’s extension phase."

Press release:
International Stem Cell Corporation Announces Successful Completion of Its Phase 1 Clinical Trial in Parkinson's Disease

"The quality of life of the patients as measured by the Parkinson's Disease Quality of Life Score-39 (PDQ-39) Summary Index, improved 43% for the second cohort at twelve months post-transplantation. This improved to a 45% better score in cohort 2 at 48 months."

I think there is a typo there, in that "48 months" should probably be "24 months". It really can't be 48 months, since cohort 2 has only been observed for 36 months.
