Brief summary

The purpose of this study is to measure the effect of IPI-549 in combination with nivolumab when compared to nivolumab monotherapy in advanced urothelial cancer patients.

Detailed description

Study IPI-549-02 is a multi-national, prospective, randomized, active-control Phase II trial to evaluate the efficacy and safety of IPI 549 administered in combination with nivolumab compared to nivolumab monotherapy. The study will enroll approximately 160 checkpoint-naïve, advanced urothelial cancer patients who have progressed or recurred following treatment with platinum-based chemotherapy. Patients will be randomized 2:1 to receive intravenous (IV) nivolumab 480 mg every 4 weeks (Q4W) in combination with oral (PO) IPI 549 40 mg once daily (QD) or IV nivolumab 480 mg Q4W in combination with placebo PO QD. Eligible patients who have confirmed progression of disease during treatment with nivolumab monotherapy may crossover to the combination treatment arm.

Interventions

IPI-549 (40mg QD) administered orally in 28-day cycles

DRUGNivolumab

Nivolumab (480mg Q4W) administered intravenously (IV) in 28-day cycles

DRUGPlacebos

Inclusion criteria

* Histologically or cytologically confirmed urothelial carcinoma of the renal pelvis, ureter, bladder, or urethra * Measurable disease by CT or MRI as defined by RECIST v1.1 * Disease progression or recurrence after treatment: * i) With at least 1 platinum-based chemotherapy regimen for the treatment of metastatic (Stage IV) or locally advanced unresectable disease; or * ii) With disease recurrence within 1 year of completing a platinum-based neoadjuvant or adjuvant therapy * Subject that have received more than 2 prior lines of chemotherapy must not have liver metastases * Tumor tissues (archived or new biopsy) must be provided for biomarker analysis * Eastern Cooperative Oncology Group (ECOG) performance status ≤1 * Blood sample must be provided for mMDSC levels for randomization into the study

Exclusion criteria

* Active brain metastases or leptomeningeal metastases * Any serious or uncontrolled medical disorder that may interfere with study treatment/interpretation * Prior malignancy active within the previous 3 years except for local or organ confined early stage cancer that has been apparently cured * Active, known, or suspected autoimmune disease * A condition requiring systemic treatment with either corticosteroids (\>10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 day of study drug administration * Prior therapy with anti-tumor vaccines, any T cell co-stimulation or checkpoint pathways, or IPI-549 * Prior surgery or gastrointestinal dysfunction that may affect drug absorption * Past medical history of interstitial lung disease * History of stroke, unstable angina, myocardial infarction, or ventricular arrhythmia requiring medication or mechanical control * Positive test for hepatitis B, C or HIV * Dependent on continuous supplemental oxygen

Design outcomes

Primary

MeasureTime frameDescription
Objective Response Rate (ORR) per RECISTv1.1First dosing date to date of confirmed disease progression, assessed up to 24 monthsORR is defined as best response of complete response (CR) or partial response (PR) as measured by RECIST v1.1. RECIST 1.1 = Response Evaluation Criteria in Solid Tumors. CR= Disappearance of all extranodal target lesions. All pathological lymph nodes must have decreased to \<10 mm in short axis. PR= At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.

Secondary

MeasureTime frameDescription
Duration of Response (DOR)Date of first objective response to date of confirmed disease progression, assessed up to 24 monthsDOR is defined as the time from the first objective response (CR or PR) to documented disease progression in patients with CR or PR.
Progression-Free Survival (PFS)First dosing to date to confirmed disease progression or death, assessed up to 48 monthsPFS is defined as the time from the first dose of study treatment to documented disease progression or death due to any cause.
Changes from baseline in thyroid stimulating hormone (TSH)Pre-treatment (within 7 days of first dose) to date of confirmed disease progression, assessed up to 24 monthsIf TSH result is abnormal, subsequent testing of Free T3 and free T4 required.
Changes from baseline in electrocardiograms (ECGs)Screening to date of confirmed disease progression, assessed up to 24 monthsECGs assess heart problems by measuring the electrical activity generated by the heart as it contracts. The components that will be assessed during the ECG are P wave, QRS complex, ST segment, and T wave.
Changes from baseline in Eastern Cooperative Oncology Group (ECOG) performanceScreening to date of confirmed disease progression, assessed up to 24 monthsECOG performance status describes the level of impact that disease has on the patient's daily living abilities. Scale ranges from 0 (Fully active and able to carry on all pre-disease performance without restriction) to 5 (Dead).
Time to Response (TTR)First dosing date to date of first objective response, assessed up to 24 monthsTTR is defined as the time from the first dose of study treatment to first objective response \[complete response (CR) or partial response (PR)\] in patients with CR or PR.
Pharmacokinetics (PK) of NivolumabPre-infusion and within 2 minutes of end of infusion on Day 1 of Cycles 1 and 4; Pre-infusion on Day 1 of Cycles 2 and 3, and every 4 cycles starting at Cycle 5 (each cycle is 28 days)Nivolumab blood concentrations will be assayed in ug/mL.
Changes from baseline in pulse rateScreening to date of confirmed disease progression, assessed up to 24 monthsPulse rate as measured in beats per minute (bpm)
Changes from baseline in temperatureScreening to date of confirmed disease progression, assessed up to 24 monthsTemperature as measured in celsius.
Changes from baseline in respiration rateScreening to date of confirmed disease progression, assessed up to 24 monthsRespiration rate as measured in breaths per minute.
Changes from baseline in blood pressureScreening to date of confirmed disease progression, assessed up to 24 monthsSystolic and diastolic blood pressure as measured in mmHg.
Population Pharmacokinetics (PK) of IPI-549-01Pre-dose, 0.5, 1.5, 3 and 6 hours following administration on Day 1 of Cycles 1 and 2 (each cycle is 28 days)IPI-549 blood concentrations in ng/mL.
