Clinical Trial Summary

To find a recommended dose of PRAME-TCR-NK cells that can be given to patients with AML or MDS.

Description:

Primary Objectives To assess dose-limiting toxicity (DLT) and determine the safety, day 30 response rate, day 180 treatment failure rate (defined as disease progression or death) and optimal cell dose of T cell receptor (TCR) modified cord blood-natural killer (CB-NK) cells (TCR-NK) targeting PRAME in patients with relapsed/refractory myeloid malignances, for each of the following diseases; AML, MDS, and Multiple Myeloma. The day 30 response rate and day 180 treatment failure rate will be estimated, and the estimates will be used to identify an optimal dose of PRAME-TCR-NK cells. Secondary Objectives - To assess the preliminary efficacy of PRAME-TCR-NK cells (Day+ 30 complete and partial response rates; Day 180 progression-free survival rate) in patients with relapsed/refractory AML, MDS, and Multiple Myeloma. - To quantify persistence of infused allogeneic donor PRAME-TCR CB-derived NK cells in the recipient as an integrated evaluation - To conduct comprehensive immune reconstitution studies. 2.2.4 To obtain preliminary data on quality of life and patient experience (PROMIS-29 quality of life questionnaire score)

3. Participants must meet disease specific eligibility criteria (see below)

4. Participants at least 3 weeks from last cytotoxic chemotherapy at the time of starting lymphodepleting chemotherapy, except for Hydroxyurea which is allowed for peripheral blood count control in AML patients until the day prior to administration of lymphodepleting chemotherapy. Patients may continue tyrosine kinase inhibitors or other targeted therapies until up to three days prior to administration of lymphodepleting chemotherapy.

5. Localized radiotherapy to one or more disease sites is allowed prior the infusion provided that there are additional disease sites that are not irradiated to assess response

6. Karnofsky Performance Scale > 50%.

7. Adequate organ function:as described in 7-10

8. Renal: Serum creatinine </= 2.0 mg/dL and estimated Glomerular Filtration Rate (eGFR using the CKD-EPI equation).GFR = 141 x [min(Scr/k), 1)a x max (Scr/k), 1) -1.209] x Age-0.993 x 1.018 [if female] x [ 1.157 if Black] (a is 0.329 for females and 0.411 for males; min indicates minimum of Scr/k or 1, and max indicates maximum of Scr/k or 1)

9. Hepatic: ALT/AST </= 2.5 x ULN or </= 5 x ULN if documented liver metastases, Total bilirubin </= 1.5 mg/dL, except in subjects with Gilbert's Syndrome in whom total bilirubin must be </= 3.0 mg/dL. No history of liver cirrhosis. No ascites.

10. Cardiac: Cardiac ejection fraction >/= 40%, no clinically significant pericardial effusion as determined by an ECHO, and no uncontrolled arrhythmias or symptomatic cardiac disease.

11. Pulmonary: No clinically significant pleural effusion (per PI discretion), baseline oxygen saturation > 92% on room air and adequate pulmonary function with FEV1, FVC and DLCO (corrected for Hgb) >50%.

12. Able to provide written informed consent.

13. All participants who are able to have children must practice effective birth control while on study and up to 3 months post completion of study therapy. Acceptable forms of birth control for female patients include: hormonal birth control, intrauterine device, diaphragm with spermicide, condom with spermicide, or abstinence, for the length of the study. If the participant is a female and becomes pregnant or suspects pregnancy, she must immediately notify her doctor. If the participant becomes pregnant during this study, she will be taken off this study. a. Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.

14. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of study agent administration. Men who are able to have children must use effective birth control while on the study. If the male participant fathers a child or suspects that he has fathered a child while on the study, he must immediately notify his doctor.

15. Signed consent to long-term follow-up protocol PA17-0483 to fulfill the institutional responsibilities to various regulatory agencies.
