Brief Summary

This first-in-human trial will assess the safety, feasibility, and efficacy of an immunotherapy with a novel CD30 antibody conjugated to a CD3 antibody that is preloaded onto a patient's own T-cells, generating a CD30 bispecific antibody-armed, anti-CD3-activated, autologous T-cells (CD30 biAb-AATC).

Detailed Description

Non-randomized, single arm, dose escalating, Phase I study evaluating the feasibility and safety of a novel anti-CD30 biAb-AATC product for adult patients with relapsed/refractory CD30+ cancer. Following T-cell collection patients are recommended to receive a bridging chemotherapy for 21 days while product is being generated and quality control assessed. Patients will then undergo weekly administration of dose escalating CD30 biAb-AATC infusions with twice weekly subcutaneous GM-CSF in 4-week cycles for a maximum of two total cycles.

If they are of childbearing potential, agree to practice a reliable method of contraception from the time of signing of the informed consent form through three months after the last dose of study drug. OR Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable contraception methods.)

c. Male patients, even if surgically sterilized (i.e., status post-vasectomy), must agree to one of the following:

i. Practice effective barrier contraception during the entire study treatment period and through three months after the last study drug dose, OR agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are not acceptable methods of contraception.)

Consent: Ability to under understand a written informed consent document, and the willingness to sign it. Voluntary written consent will be documented before initiation of study-related procedures not part of normal medical care. Consent may be withdrawn by the subject/guardian without prejudice to future medical care.

Exclusion Criteria

Prior Therapy: Any toxicities from prior treatment, >Grade 3 per CTCAE v5.0 Hematopoietic stem cell transplantation (HCT) or chimeric antigen receptor T-cell therapy (CAR-T cell) within 60 days of enrollment, or evidence of veno-occlusive disease (VOD) at any time post-transplant.

Investigational Agent: Treatment with any investigational agent within 14 days of enrollment.

Exclusion Requirements Due to Comorbid Disease or Concurrent Illness:

Immune: Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. Steroid premedication for imaging scans is allowed. Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.

Infectious: Systemic fungal, bacterial, viral, or other infection not controlled (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment). Patients with possible fungal infections must have had appropriate anti-fungal antibiotics and adequately controlled. HIV-positive patients on combination antiretroviral therapy are ineligible because of the unknown ability to expand T cell populations for CD30 biAb-AATC product in this setting. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.

Pulmonary: Prior history of anti-CD30 therapy related pulmonary toxicity.

Neurologic: Prior history of progressive multifocal leukoencephalopathy (PML).

Cardiac: Patients diagnosed with NYHA Class III or IV congestive heart failure, ventricular arrhythmias, or uncontrolled hypertension.

Allergies: Known hypersensitivity or allergic reaction attributed to any of the components of CD30 biAb-AATC or to compounds of similar composition to CD30 targeted agent, or a bispecific Antibody-armed activated autologous T cell product.

Pregnant or Breastfeeding: Pregnant or breastfeeding females will not be allowed to enroll on this study. Female patients with infants must agree not to breastfeed their infants during the entire study treatment period and through three months after the last study drug dose. Agents used in this study are known to be teratogenic to a fetus. There is there is no information on the excretion of CD30 biAb-AATC agents into breast milk but potential risk for adverse events in nursing infants secondary to treatment of the mother with a CD30 biAb-AATC.

Secondary Malignancy: Patients should not have a history of any second malignancy in the last 1 year with exception of the diagnosis for inclusion; subjects with prior history of in situ cancer or basal or squamous cell skin cancer are eligible. Subjects with other malignancies are eligible if they have been continuously disease free for at least 1 year.
