- 3. No other prior aGVHD treatment
- 4. Steroid Refractory
- Progressed after 3 days of treatment with 2 mg/kg methylprednisolone (MPE)
- No improvement after 7 days of treatment with 2 mg/kg MPE
- Progressed to a new organ after treatment with 1 mg/kg MPE for skin or upper gastrointestinal (UGI) aGVHD

CK0802 Tregs will be administered intravenously at a fixed dose of 100 million Treg cells.

Subjects will receive seven planned doses of CK0802 on study day +1, +3 (+/-1 day), +5 (+/-1 day), +7 (+/- 2 day), +14 (+/- 3 days), +21 (+/-3 days) and +28 (+/-3 days). A total of 7 doses will be administered. If Day 29 assessment shows PR or MR, then 4 additional weekly infusion of CK0802 Tregs can be administered (study days: 35 (+/- 2 day), 42 (+/- 2 day), 49 (+/- 2 day), and 55(+/- 2 day)), for a total of 11 infusions |

Non-Hematologic: Any ≥ Grade 3 non-hematologic AE as per CTCAE v6.0 Hematologic: Any new or worsened Grade 4 neutropenia, thrombocytopenia, or anemia compared with baseline that persists for >7 days despite supportive care and is not clearly and incontrovertibly attributable to the underlying disease or another extraneous cause.

Overall Response (OR) at day +29. Overall response (OR) will include complete response (CR) and partial response (PR). Response to be determined from the maximum acute GVHD stage and grade in each organ. Complete Response (CR): Stage 0 in all organs (skin, liver, and GI tract) and no intervening additional therapy Partial Response (PR): Improvement of at least 1 stage in 1 or more organs without progression in other organs, and no intervening additional therapy Overall Response (OR): Includes both CR and PR Very Good PR (VGPR): Improvement by at least one stage in one or more organs and
