- Current alcohol or chemical abuse, or mental or psychiatric condition precluding protocol compliance
- Pregnant or nursing
- Allergy to soy, egg, or peanut products
- Receiving another investigational agent (30 day wash-out required prior to first dose)

Phase I: HS-410 Low Dose
Phase II: HS-410 Low-Dose Plus BCG
Phase II: High-Dose HS-410 Plus BCG
Phase II: Placebo Plus BCG
Phase II: High-Dose HS-410
In the open label Phase 1 portion, HS-410 is given as 1*10^6 cells per dose for 12 weekly injections followed by 3 monthly injections.
In the Phase 2 portion, HS-410 is given as 1*10^6 cells per dose weekly for 6 weeks in combination with BCG, followed by 6 weeks of HS-410 alone, and then 3 courses of three once-weekly doses of HS-410 in combination with BCG.
In the Phase 2 portion, HS-410 is given as 1*10^7 cells per dose weekly for 6 weeks in combination with BCG, followed by 6 weeks of HS-410 alone, and then 3 courses of three once-weekly doses of HS-410 in combination with BCG.
In the Phase 2 portion, a placebo is given weekly for 6 weeks in combination with BCG, followed by 6 weeks of placebo alone, and then 3 courses of three once-weekly doses of placebo in combination with BCG.
In the Phase II portion, if patients will not receive BCG, HS-410 is given as 1*10^7 cells per dose weekly for 12 weeks, and then 3 courses of three once-weekly doses of HS-410.
