Brief Summary:

This study will find the highest acceptable treatment dose and timing of infusion of cord blood, culture expanded natural killer (NK) cells, a kind of immune cell, in patients with multiple myeloma.

The NK cells will be given at varying days post autologous stem cell transplant. rhIL-2 is administered after treatment to help the NK cells expand in the body. The safety of this treatment will be studied and researchers want to learn if NK cells will help in treating multiple myeloma.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: rhIL-2 Biological: PNK-007 Phase 1

Detailed Description:

The primary objective of the study is to assess safety and determine the maximum tolerated dose of PNK-007 as well as the feasibility of treating at various timepoints following ASCT in subjects with multiple myeloma. The secondary objective is to explore the potential clinical efficacy by day 90-100 post ASCT.

Treatment plan includes ASCT followed by PNK-007 which will be administered IV Day 14 post ASCT to determine the maximum tolerated dose. Once the IV Day 14 post ASCT. PNK-007 will be followed by up to six rhIL-2 injections to support the NK cells expansion in the body.

Subjects will be followed for up to 12 months post PNK-007.

Arm Intervention/treatment
Experimental: PNK-007 and rhIL-2
Melphalan per institutional practices (within Day -5 to 01), ASCT (Day 0), PNK-007 at varying dose levels (within Day 7 to Day 14) and rhIL-2 every other day starting day of PNK-007 administration.
Drug: rhIL-2
Human recombinant Interleukin-2

Biological: PNK-007
PNK-007 is a culture-expanded cell population derived from human cord blood hematopoietic stem/progenitor cells.

Primary Outcome Measures :

    Number and severity of adverse events within 28 days of administration

  2. Maximum Tolerated Dose (MTD) [ Time Frame: Up to 28 days ]
    The maximum dose safely administered for the treatment of patients with multiple myeloma

  3. Dose Timing After Autologous Stem Cell Transplant [ Time Frame: Up to 28 days ]
    The optimal dose timing safely administered for the treatment of patients with multiple myeloma post ASCT

  4. Adverse Events (AEs) [ Time Frame: Up to 12 months ]
    Number and severity of adverse events within 12 months of administration

Secondary Outcome Measures :
  1. Response Rate [ Time Frame: Up to day 100 ]
    Clinical efficacy at day 90-100 post ASCT per International Myeloma Working Group criteria, including minimal residual disease

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Subjects must satisfy the following criteria to be enrolled in the study:

  1. Subject has eligible disease status:

    1. Newly diagnosed and are undergoing induction therapy prior to undergoing first Autologous stem cell transplant (ASCT) or
    2. Myeloma patients with prior relapse undergoing first ASCT. or
    3. Myeloma patients with relapsed disease after first ASCT who are undergoing second ASCT. Subjects must have achieved at least a partial response (PR) prior to proceeding to ASCT.
  2. Subject is > 18 and ≤ 70 years of age at the time of signing the informed consent form (ICF).
  3. Subject must understand and voluntarily sign an ICF prior to any study-related assessments/procedures being conducted.
  4. Subject is willing and able to adhere to the study schedule and other protocol requirements.
  5. Performance status of Karnofsky performance status ≥ 70% or Eastern Cooperative Oncology Group (ECOG) < 2
  6. Ability to be off immunosuppressive drugs for at least 3 days prior to the PNK-007 cell infusion. Steroids at the equivalent of no more than 5 mg prednisone per day are permissible.
  7. Be a candidate for ASCT based on institutional practices.
  8. Subjects must have autologous peripheral blood stem cell graft available in storage for additional transplant in the event of engraftment failure.
  9. Female of childbearing potential (FCBP) must:

    1. Have two negative pregnancy tests as verified by the Investigator prior to starting study therapy. She must agree to ongoing pregnancy testing during the course of the study, and after the end of study treatment. This applies even if the subject practices true abstinence* from heterosexual contact.
    2. Either commit to true abstinence* from heterosexual contact (which must be reviewed at applicable study visits and source documented) or agree to use, and be able to comply with, effective contraception without interruption, during the study therapy (including dose interruptions), and for 28 days after discontinuation of PNK-007.

      A female of childbearing potential (FCBP) is a female who:

      1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months).
