Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - CYP-001: Cymerus induced pluripotent stem cell (iPSC)-derived mesenchymal stem cells (MSCs)
Treatment: Other - Placebo
Treatment: Drugs - Corticosteroids

Experimental: CYP-001 plus corticosteroids -

Placebo comparator: Placebo plus corticosteroids -


Treatment: Other: CYP-001: Cymerus induced pluripotent stem cell (iPSC)-derived mesenchymal stem cells (MSCs)
Cymerus MSCs are derived from iPSCs using the proprietary Cymerus platform technology.

Treatment: Other: Placebo
The placebo product is identical to CYP-001, except that it contains no active agent

Treatment: Drugs: Corticosteroids
All enrolled subjects in this trial must receive corticosteroids at a minimum dose of oral prednisone 2 mg/kg/day (or methylprednisolone 1.6 mg/kg/day IV) as therapy for aGvHD for at least for 72 hours post enrollment.
