What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 43 participants in total. It began in 2022-04-29 with a primary completion date of 2026-09-01.

Brief Summary

This phase Ib trial tests the safety, side effects, and best dose of tumor treating fields therapy in combination with either cabozantinib or nab-paclitaxel and atezolizumab in treating patients with solid tumors involving the abdomen or thorax that have spread to other parts of the body (advanced). Tumor treating fields therapy on this study utilizes NovoTTF systems that are wearable devices that use electrical fields at different frequencies that may help stop the growth of tumor cells by interrupting cancer cells' ability to divide. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals tumor cells to multiply. This helps slow or stop the spread of tumor cells. Chemotherapy drugs, such as nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving tumor treating fields therapy in combination with either cabozantinib, or with nab-paclitaxel and atezolizumab may help control advanced solid tumors involving the abdomen or thorax.

Childbearing potential will be defined as women who have had menses within the past 12 months and who have not had a tubal ligation, hysterectomy, or bilateral oophorectomy. Should a woman become pregnant or suspect that she is pregnant while participating in this study, she should inform her treating physician immediately. Male participants must agree to use effective contraception or abstinence while on study. * Able to operate the TTF device independently or with the help of a caregiver. Exclusion Criteria: * Participants must not receive prior anticancer therapy or radiation therapy within 2 weeks and must not undergo major surgery within 4 weeks prior to initiation of treatment on protocol. Participants who are already on cabozantinib and have progressive disease are allowed to transition to treatment with tumor treating fields and cabozantinib. Participants in both cohorts who already started treatments as standard of care (Cohort 1: Cabozantinib and Cohort 2: nab-paclitaxel and Pembrolizumab) are allowed to start on protocol within the first 2-3 weeks of treatment initiation. Palliative radiation therapy is allowed. * Participants must have recovered to Grade 0-1 toxicity from prior therapy. * Active brain metastasis or leptomeningeal disease. Patients with treated brain metastasis must have stable disease, evidenced by brain imaging for at least 4 weeks and the patient must have been off steroids for at least 2 weeks. * The patient has cardiac conditions as follows: uncontrolled: hypertension (blood pressure \[BP\] \> 160/100) despite optimal therapy, uncontrolled angina, ventricular arrhythmias, congestive heart failure (New York Heart Association Class II or above), prior or current cardiomyopathy, uncontrolled atrial fibrillation with heart rate \> 100 beats per minute (bpm), unstable ischemic heart disease (myocardial infarction within 6 months prior to starting treatment or angina requiring use of nitrates more than once weekly). * The patient has concurrent severe and/or uncontrolled medical disease that could compromise participation in the study (i.e., uncontrolled diabetes, severe infection requiring active treatment, severe malnutrition, chronic severe liver or renal disease). * Concurrent malignancies are permitted if (A) they were previously treated, and all treatment of that malignancy was completed at least 2 years before enrollment and no evidence of disease exists, or (B) with agreement from the Principal Investigator (PI), participants who have a concurrent malignancy that is clinically stable and does not require tumor-directed treatment are eligible to participate if the risk of the prior malignancy interfering with either safety or efficacy endpoints is very low, or (C) with agreement from the PI, other malignancies may be permitted if the risk of the prior malignancy interfering with either safety or efficacy end points is very low.
