Kidney Cancer Clinical Trial
Study of CAR.70-engineered IL15-transduced Cord Blood-derived NK Cells in Conjunction With Lymphodepleting Chemotherapy for the Management of Advanced Renal Cell Carcinoma, Mesothelioma and Osteosarcoma
To find a recommended dose of donated NK cells that can be given with lymphodepleting chemotherapy to patients with advanced renal cell carcinoma, mesothelioma, or osteosarcoma. The effects of this therapy will also be studied.
To determine the safety and optimal cell dose of chimeric antigen receptor (CAR).70/interleukin (IL)15-transduced cord blood (CB)-derived natural killer (NK) cells in patients with advanced renal cell carcinoma, advanced mesothelioma, and advanced osteosarcoma.
To determine the antitumor activity of CAR.70/IL15-transduced CB-derived NK cells. Although the clinical benefit of CAR.70/IL15-transduced CB-derived NK cells has not yet been established, the intent of offering this treatment is to provide a possible therapeutic benefit and thus, the patient will be carefully monitored for tumor response and symptom relief in addition to safety and tolerability. Efficacy will be determined in each of the three cohorts.
To quantify the persistence of infused allogeneic donor CAR-transduced CB-derived NK cells in the recipient.
To conduct comprehensive immune reconstitution studies.
To obtain preliminary data on quality of life and patient experience.

Aged 18-80 years.
Weight ≥40 kg.
All male and female patients who are able to have children must practice effective birth control while on study therapy and for 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. Female patients who become pregnant or suspect pregnancy must immediately notify their doctor. Females patients who become pregnant will be taken off study. Men who are able to have children must use effective birth control while on the study therapy. Acceptable forms of birth control for male patients include: condom with spermicide or abstinence. If the male patient fathers a child or suspects that he has fathered a child while on the study, he must immediately notify his doctor.
Negative serum or urine beta human chorionic gonadotropin pregnancy test for females of childbearing potential (defined as not postmenopausal for 24 months or no previous surgical sterilization or lactating females) at screening.
Disease-specific inclusion criteria:

Patients must have a histologically confirmed diagnosis of Stage 4 RCC with a clear cell component.

Patients must have at least 1 measurable lesion >10 mm on computed tomography (CT) per the RECIST v1.1.
Patients must have pathologically confirmed mesothelioma
Patients must have progressive, recurrent, or refractory disease (local recurrence) or new disease after all curative measures, including first-line chemotherapy, targeted therapy, and radiotherapy
Patients must have measurable or evaluable disease per the RECIST v1.1 at enrollment.
Patients must have histologically confirmed osteosarcoma that is recurrent or refractory and for which standard curative measures do not exist or are no longer effective. Must have histologic verification of their disease at diagnosis or at relapse.

Patients must have evaluable or measurable disease per the RECIST v1.1 at enrollment.
Patients who meet any of the following criteria will be excluded from study entry:
Presence of clinically significant ≥ Grade 3 toxicity from previous anticancer treatment, as determined by the PI.
Presence of fungal, bacterial, viral, or other infection requiring IV antimicrobials for management or not responding to appropriate therapy.
