Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Sulforaphane | Sulforaphane (SF) will be administered once a day orally in an approximate dose of 1 µmol/lb (2.2 kg µmol/kg) body weight. Each SF tablet will contain 125 mg broccoli seed powder (equivalent to \~ 15 µmol SF). The total dose per day will depend on participants' body weight:~30-50 lb: 3 tablets (45 µmol/day) 50-70 lb: 4 tablets (60 µmol/day) 70-90 lb: 6 tablets (90 µmol/day) 90-110 lb: 7 tablets (105 µmol/day) 110-130 lb: 8 tablets (120 µmol/day)~For pilot study, all participants (n=10) will receive SF for 14 days. For main clinical trial, 25 participants will randomly receive SF for 15 weeks (phase 1). During phase 2, a single-arm crossover from placebo to sulforaphane arm will take place, and all participants will receive SF from 15-30 weeks.~Sulforaphane: See under active arm description | 0 | 32 | EG000 |
| Group 2 | Placebo | Placebo tablets identical in size and similar in appearance to the active tablets will be used. Number of placebo tablets will be equivalent to the active tablets depending on participants' body weight.~For the main clinical trial, 25 participants will be randomly allocated to receive placebo for 15 weeks (phase 1). During phase 2, a single-arm crossover from placebo arm to sulforaphane arm will take place, and all participants will receive sulforaphane from 15-30 weeks.~Placebo: See under placebo arm description | 0 | 23 | EG001 |

Harm
- What it counts
- Total, all-cause mortality
- Time frame
The pilot study took place over 2 weeks for each of 10 participants. The main study took place over 2 years, 6 months; 1/1/16 - 6/30/18 for 45 participants, each of whom was assessed from screening (time 0), 7, 15, 22 and up to 36 weeks for the final visit. Participants in the pilot study were followed for adverse events during regular clinical visits for at least 12 months after the study and none were reported.
