Brief Title: (CLONEVO): Cell cycLe inhbitiON to Target the EVolution of UrOthelial Cancer

A Window-of-opportunity Trial of Abemaciclib Followed by Radical Cystectomy in Patients With Platinum-ineligible Urothelial Carcinoma to Evaluate CDK4/6-dependent Phosphorylation of Pocket Proteins and Clonal Evolution Dynamics

  • NTC ID: NCT03837821
  • Sponsor: Weill Medical College of Cornell University


Single-arm, open-label window-of-opportunity trial of neoadjuvant Abemaciclib in 20 patients, with tumor tissue obtained as standard of care at tumor resection (pre-Abemaciclib) and cystectomy (post-Abemaciclib)


A Window-of-Opportunity Trial of Abemaciclib followed by radical cystectomy in patients with Platinum-Ineligible Urothelial Carcinoma to Evaluate CDK4/6-Dependent Phosphorylation of Pocket Proteins and Clonal Evolution Dynamics. Subjects will be treated with Abemaciclib at 200 mg every 12 hours for at least 4 weeks (and likely slightly longer depending upon surgical date). Individual dose reductions will be made on the basis of the AEs observed. In the absence of treatment delays due to adverse event(s), treatment will be continued until the surgical date unless any of the following criteria applies: 1-Disease progression; 2-Intercurrent illness that prevents further administration of treatment; 3-Unacceptable adverse event(s) as a result of Abemaciclib; 4- Patient decides to withdraw from the study; 5-General or specific changes in the patient's condition render the patient unacceptable for further treatment in the judgment of the investigator. Patients will be followed with history, physical, and blood tests at each visit to monitor for toxicity. Patients will be followed for survival endpoints following completion of this study for 3 years after surgery or until death. Patients removed from study for unacceptable adverse events will be followed until resolution or stabilization of the adverse event.

Inclusion Criteria
Age ≥ 18 years old at time of informed consent

- Histologically confirmed MIBC (T2-T4) pure or mixed histology urothelial carcinoma [urothelial carcinoma should be the dominant (>50%) histology].
Refusing cisplatin-based chemotherapy or ineligible for cisplatin-based chemotherapy due to at least one of the following:
Creatinine clearance < 60 mL/min (by Cockgroft-Gault calculation and/or measured creatinine clearance) - Hearing loss ≥ grade 2 by CTCAE criteria and/or; - Neuropathy ≥ grade 2 by CTCAE criteria and/or - Heart failure NYHA ≥ III - Medically fit for TURBT and radical cystectomy
Adequate organ and marrow function as defined below:
Absolute neutrophil count ≥ 1.5 K/mm3

- White blood cell count (WBC) > 3.0 K/mm3

- Platelets ≥ 100 K/mm3

- Hemoglobin ≥ 9 g/dL

- Serum total bilirubin ≤ 1.5 x ULN (Patients with Gilbert's syndrome with a total bilirubin ≤2.0 times ULN and direct bilirubin within normal limits are permitted)

- ALT and AST ≤ 2.5 x ULN

- Ability to swallow oral medications

- Patients who received radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and randomization
Exclusion Criteria
Patients with locally advanced unresectable or metastatic urothelial carcinoma as assessed on baseline radiographic imaging obtained within from the date of signed consent, 28 days prior to study enrollment. Low volume (<1.5 cm) suspicious lymph node metastases in the pelvis are allowed if they are in the LN dissection template field. The required radiographic imaging includes:
Abdomen/pelvis - CT/MRI

- Chest - chest x-ray or CT scan

- Bone scan or FDG-PET/CT in the presence of bone pain or unexplained elevated alkaline phosphatase

- Patients with another active second malignancy other than non-melanoma skin cancers and localized prostate cancer. Patients that have completed all necessary therapy and are considered to be <30% risk of relapse are not considered to have an active second malignancy and are eligible for enrollment. - Patients who have received anti-cancer therapy including chemotherapy, radiotherapy, immunotherapy, and monoclonal antibodies ≤ 4 weeks prior to starting study drug, or who have not recovered from the side effects of such therapy - Patients who have serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea). - Have an active active bacterial infection (especially if requiring IV antibiotics), systemic fungal and/or known viral infection (for example, human immunodeficiency virus antibodies, hepatitis B surface antigen, or hepatitis C antibodies). - Subjects who received a strong CYP3A inhibitor within 7 days prior to the first dose of study drug, or patients who require continuous treatment with a strong CYP3A inhibitor - The patient has a personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest. - Pregnant or breast-feeding women - Women who do not agree to use a medically approved contraceptive method during the treatment period and for 3 months following the last dose of Abemaciclib - Men who do not agree to use a reliable method of birth control and to not donate sperm during the study and for at least 3 months following the last dose of Abemaciclib - Subjects unwilling or unable to comply with the protocol
