Results:
A significant improvement in mean UPDRS part III motor scores off medication was recorded in all patients at 6 months (mean score 38 [SD 9] vs 26 [8], n=15, p=0·0001) and 12 months (38 vs 27 [8]; n=15, p=0·0001) compared with baseline.

The study enrolled 12 patients, with ages ranging from 60 to 78 in the U.S. and 50 to 78 in Canada. These patients had been diagnosed with Parkinson's disease for a duration of three to 20 years and had previously been treated with levodopa, but experienced incomplete response to the medication.

□ The secondary objectives will be to assess the evidence of transplanted cell survival and motor effects at one- and two-years post-transplant, to evaluate continued safety and tolerability at two years, and to assess feasibility of transplantation

*Twenty-two subjects were dosed but six were eliminated from efficacy analysis due to mistargeting of cannula. **Two 5 μl volumes infused via single needle tract ~4 mm apart. # Described as a Phase 1/2 trial, this open label (uncontrolled) study does not differ substantially from many dose-escalation Phase 1 safety studies that include secondary efficacy endpoints; thus, the distinction appears to be more a semantic preference than a reflection of a substantial difference in study design.

A five-fold dose range was tested involving 3 dose levels (1.9X107 transducing units (TU); 4.0X107 TU; 1.0X108 TU).

Uncertain Spans

  • “(Axovant) ProSavin” — this row’s left target/category cell is cut off above the visible top of the page; the visible drug-name cell reads “(Axovant) ProSavin”.
  • “CEP-1347” — the leftmost edge of the row is truncated by the tile boundary; only “EP-1347” is fully visible. Transcribed as the standard literature name “CEP-1347” (Cephalon’s MLK inhibitor); the leading “C” is inferred but not visible in this page’s crop.
  • “MTX325 and MTX652, ough, Mission Therapeutics” — the company name appears wrapped across lines as “…ough, Mission” + “…erapeutics”; transcribed as “Mission Therapeutics” with the partial “…ough” prefix preserved; the prefix may correspond to an earlier word (“Forbough”/“…ough”) that is cut off at the left edge.
  • “M-Au8® (Clene)” Primary outcome — sentence ends mid-clause “the mean NAD+/NADH ratio in the …”; the continuation falls outside this page.
