  • Radiation therapy for bone metastasis ≤ 2 weeks, any other radiation therapy within 4 weeks before first dose of study treatment. Systemic treatment with radionuclides within 6 weeks before the first dose of study treatment. Subjects with clinically relevant ongoing complications from prior radiation therapy are not eligible.
  • Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least 4 weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
  • Concomitant anticoagulation with oral anticoagulants except for those specified below.
  • Allowed anticoagulants are the following:
  • Prophylactic use of low-dose aspirin for cardioprotection (per local applicable guidelines) is permitted.
  • Low-dose low molecular weight heparins (LMWH) are permitted.
  • Therapeutic doses of LMWH or anticoagulation with direct factor Xa inhibitors rivaroxaban, edoxaban, or apixaban is allowed in subjects without known brain metastases who are on a stable dose of the anticoagulant for at least 1 week before the first dose of study treatment without, clinically significant hemorrhagic complications from the anticoagulation regimen or the tumor.
  • The subject has prothrombin time (PT)/INR or partial thromboplastin time (PTT) test ≥ 1.3 × ULN within 14 days before the first dose of study treatment.
  • The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions:
  • Cardiovascular disorders:
  • Ongoing congestive heart failure exacerbation or New York Heart Association Class 4, unstable angina pectoris, serious cardiac arrhythmias.
  • Uncontrolled hypertension defined as sustained blood pressure (BP) > 150 mm Hg systolic or > 100 mm Hg diastolic despite optimal antihypertensive treatment. Uncontrolled hypertension needs to be determined based on persistently high blood pressure readings over more than 24 hours and should NOT be based on the blood pressure readings from one clinic visit. Blood pressure readings done at home or by primary care providers are acceptable. If a blood pressure reading on the day of screening is high, but there are documented acceptable ( ≤150 mm Hg systolic and ≤100 mm Hg diastolic) blood pressure readings prior to or after the screening visit (with or without the use of anti-hypertensive medications), patient will not be considered to have uncontrolled hypertension.
  • Stroke (including transient ischemic attack [TIA]), myocardial infarction (MI), or other ischemic event, or symptomatic thromboembolic event (eg, deep venous thrombosis, pulmonary embolism) occurring less than or equal to 6 months before first dose of cabozantinib. [Note: Subjects with a diagnosis of deep vein thrombosis (DVT) or incidentally detected asympotmatic and sub-segmental pulmonary embolism (PE) on routine scans are allowed if on a stable dose of anti-coagulation for at least 1 week before first dose of study treatment].
  • Clinically significant hematuria, hematemesis, or hemoptysis of > 0.5 teaspoon (2.5 ml) of red blood, or other history of significant bleeding (eg, pulmonary hemorrhage) within 12 weeks before first dose.
  • Gastrointestinal (GI) disorders including those associated with a high risk of perforation or fistula formation:
  • The subject has evidence of tumor invading the GI tract, active peptic ulcer disease, inflammatory bowel disease (eg, Crohn's disease), diverticulitis, cholecystitis, symptomatic cholangitis or appendicitis, acute pancreatitis, acute obstruction of the pancreatic duct or common bile duct, or gastric outlet obstruction.
  • Abdominal fistula, GI perforation, bowel obstruction, or intra-abdominal abscess within 6 months before first dose.
  • Note: Complete healing of an intra-abdominal abscess must be confirmed before first dose.
  • Cavitating pulmonary lesion(s) or known endotracheal or endobronchial disease manifestation.
  • Lesions invading or encasing any major blood vessels.
  • Other clinically significant disorders that would preclude safe study participation per investigator clinical judgement.
  • Serious non-healing wound/ulcer/bone fracture.
  • Uncompensated/symptomatic hypothyroidism.
  • Moderate to severe hepatic impairment (Child-Pugh B or C).
  • Other severe acute or chronic medical conditions including immune colitis, inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
  • Major surgery (eg, GI surgery, removal or biopsy of brain metastasis) within 8 weeks before first dose of study treatment. Complete wound healing from major surgery must have occurred 1 month before first dose and from minor surgery (eg, simple excision, tooth extraction) at least 10 days before first dose. Subjects with clinically relevant ongoing complications per investigator clinical judgement from prior surgery are not eligible.
  • Corrected QT interval calculated by the Fridericia formula (QTcF) > 500 ms per electrocardiogram (ECG) within 28 days before first dose of study treatment.
  • Note: If a single ECG shows a QTcF with an absolute value > 500 ms, two additional ECGs at intervals of approximately 3 min must be performed after the initial ECG, and the average of these three consecutive results for QTcF will be used to determine eligibility.
  • Diagnosis of another malignancy within 2 years before first dose of study treatment, with the exception of those determined by the treating investigator to have a negligible risk of metastasis or death (such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, ductal carcinoma in situ treated surgically with curative intent, localized prostate cancer treated with curative intent and/or no intent for further treatment, or incidental prostate cancer)
  • Current use of immunosuppressive medication, EXCEPT for the following: a. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection); b. Systemic corticosteroids at physiologic doses ≤ 10 mg/day of prednisone or equivalent; c. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication).
  • Has active autoimmune disease currently requiring systemic treatment with high dose corticosteroids (dose more than physiologic replacement doses equivalent to prednisone 10 mg daily) or (disease modifying immunosuppressive agents). Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, intranasal, inhaled, topical steroids, or local steroid injection) is not considered an exclusion.
  • Active autoimmune disease that might deteriorate significantly when receiving an immuno-stimulatory agent per treating physician's clinical judgment. Subjects with diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid diseases not requiring immunosuppressive treatment are eligible.
  • Prior organ transplantation including allogenic stem-cell transplantation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Count of Participants With Response Measured by RECIST 1.1

    To evaluate measurable disease overall response. Subjects were evaluated by CT scans at regular intervals for disease assessment by RECISTv1.1 criteria for the duration of treatment.

    Response Evaluation Criteria in Solid Tumors (RECIST) is a standard measure of how well cancer patients respond to treatment. Possible scores are CR (Complete Response; total disappearance of all target lesions), PR (Partial Response; at least a 30% decrease of the sum of the longest diameter of all target lesions), PD (Progressive Disease; at least a 20% increase of the sum of the longest diameter of all target lesions), and SD (Stable Disease; neither a sufficient decrease for PR, or sufficient increase for PD). Overall response is the count of PR and CR scores among the participants' best RECISTv1.1 responses.

    Measured: From baseline disease assessment to best response disease assessment, measured up to 28 months.

Secondary outcomes (3)

  1. Count of Participants Who Were Progression-free at the Completion of Study Follow-up (PFS).

    To evaluate progression-free survival at completion of study follow-up (PFS). PFS is defined as the count of participants who remained alive and progression-free completion of their follow-up period. Participants were followed up to six months after completion of the study treatment.

    Subjects were evaluated by CT scans at regular intervals for disease assessment by RECISTv1.1 criteria (as described in the primary outcome) for the duration of treatment.

    Measured: Up to 34 months from the start of the study treatment.

  2. Count of Overall Survival (OS) at Completion of Study Follow-up

    To evaluate Overall Survival (OS) at completion of study follow-up. OS is defined as the count of participants who remained alive after their follow-up period. Participants were followed up to six months after completion of the study treatment.

    Subjects were followed via telephone contact or medical record review for survival 6 months after completing the study treatment.

    Measured: Up to 34 months from the start of the study treatment.

  3. Occurrence of Adverse Events and Serious Adverse Events

    To evaluate toxicities associated with the combination treatment. Subjects were monitored for adverse events from the start of treatment through 30 days after the last dose of study treatment, and serious adverse events were collected until 90 days after the cessation of study treatment.

    The severity of adverse events was assessed using CTCAE v5.0 criteria, a 1-5 scale with higher numbers indicating greater severity. Grade 1 indicates "mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated" and Grade 5 indicates "death related to AE". The treating investigator evaluated each adverse event to assess its attribution to the study treatment.

    This outcome measure will report the following:

    • The count of participants who had a grade 1-2 event, related to study treatment.
    • The count of the participants who had a grade 3-4 event, related to study treatment.
    • The count of the participants who had a grade 5 event or higher,

    Measured: Up to 31 months from the start of study treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cabozantinib and Pembrolizumab in people with Metastatic Urothelial Carcinoma and Bladder Cancer, run by University of Utah at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 50 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Nov 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Count of Participants With Response Measured by RECIST 1.1 (time frame: From baseline disease assessment to best response disease assessment, measured up to 28 months.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03534804.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
