General information about the trial
|
|||
Main objective of the trial |
To demonstrate the benefit of maintenance treatment with avelumab plus BSC vs. BSC alone in prolonging overall survival (OS) in subjects with unresectable locally advanced or metastatic UC whose disease did not progress on or following completion of first-line platinum-containing chemotherapy in each co-primary UC subject population: 1) subjects determined to have Programmed Death-Ligand 1 (PD-L1) positive tumors (including infiltrating immune cells) by a verified Good Manufacturing Practice (GMP) PD-L1 Immunohistochemistry (IHC) test , and 2) all randomized subjects.
|
||
Protection of trial subjects |
The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Council for Harmonization (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trials subjects were followed.

Progression-Free Survival (PFS) as Assessed by Blinded Independent Central Review (BICR) | ||||||||||||
End point description |
BICR assessed PFS: PD as per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 was defined for target disease as at least a 20% increase in sum of diameters of target lesions, taking as reference smallest sum on study (included baseline sum if that was smallest on study). In addition to relative increase of 20%, sum must have also demonstrated an absolute increase of at least 5 millimeters. For non-target disease: PD: unequivocal progression of pre-existing lesions and if overall tumor burden increased sufficiently to merit discontinuation of therapy. Appearance of any new unequivocal malignant lesion was also considered PD. Analysis was performed using Kaplan-Meier. PFS data was censored on date of last adequate tumor assessment for subjects with no event (PD or death), who started new anti-cancer therapy prior to an event or with an event after 2 or more missing tumor assessments. Full analysis set was analysed.

NCCN-FACT FBlSI-18 is an 18-item subject completed questionnaire, designed to assess impact of cancer therapy/urothelial cancer-related symptoms and quality of life based on numerical point scoring of symptoms/concerns.Included four subscales: Disease related symptoms(DRS)-physical subscale (9 items), DRS-emotional subscale(2), treatment side effects subscale with (5)&general function/well-being subscale(2). Subjects rated their level of symptoms for each item using 5-point scale ranging from 0=not at all to 4=very much. Items that were negatively framed, and the scores were reversed for analysis so that higher scores= good quality of life. Overall score: total of 18 items, ranging from 0=severely symptomatic to 72=asymptomatic. Higher scores= better functioning or lower symptom burden. Full analysis set.

17 Dec 2015 |
Amendment 1: Per FDA request, implemented clarifications in section 5.4.3.5, table 5 management of Avelumab irAEs: Clarified requirement for delaying or discontinuing avelumab for Grade 3 or 4 dermatological irAEs. Clarified requirement to delay or discontinue avelumab therapy for suspicion of adrenal crisis. Per FDA request, added a requirement in section 5.4.3.5, table 5, to permanently discontinue avelumab therapy for subjects with AST/ALT >3 x ULN with concurrent elevation of total bilirubin >2 x ULN without another obvious cause. Inclusion criterion #11 was revised to allow enrollment of patients with a creatinine clearance (CrCl) ≥30 mL/min (changed from ≥50 mL/min). |
||
24 Mar 2016 |
Amendment 2: Added an HIV screening test unless not permitted by local laws and regulations (schedule of activities table and footnote #12; and table 6, section 7.1.3) and exclusion of HIV positive subjects (exclusion criterion #16, Section 4.2). Clarified that exclusion criterion #21 (section 4.2) includes but is not limited to those medical conditions listed, and add ‘pulmonary fibrosis’ as a listed condition. Clarified in Section 7.1.3 that the requirement to repeat abnormal laboratory test results applies only for clinically significant abnormal results. |
||
19 Dec 2016 |
Amendment 3: To mitigate the potential for bias in determining disease progression, an expedited blinded independent central review (BICR) for investigator-assessed disease progression was added. To optimize trial logistics, removed the requirement for central eligibility review of first-line chemotherapy response. Per United States FDA request, to assess the utility of serum troponin measurements in early detection of myocarditis, a rare and potentially fatal risk associated with avelumab and other check-point inhibitors, the following additions were made: Mandatory measurement of cardiac troponin levels at screening and at each clinic visit ending on Cycle 4 Day 1 (ie, for a total of 12 weeks), and as clinically indicated; Management guidelines for myocarditis. Clarified that first-line chemotherapy must have been completed no less than 4 weeks and no more than 10 weeks prior to randomization (inclusion criterion 2a). |

Amendment 4: immune-related Response Criteria (irRECIST) has been removed as an exploratory endpoint and required study assessment. Management of avelumab-related toxicity has been updated to reflect current avelumab program standard recommendations (Section 5.4.3). Premedications to mitigate avelumab infusion-related reactions were revised such that premedication is only required for the first 4 infusions. Contraception requirements have been updated for females and males in accordance with the current Pfizer and avelumab program standards. The contraception check and pregnancy test were removed as required study procedures at the 60 Day Follow-up visit, in accordance with the current avelumab program standard. It has been added that if new cancer therapy is started, reporting of concomitant medications should end at the time the new cancer therapy starts in order to match the AE reporting period, and in accordance with the current avelumab program standard.Survival assessments for long-term follow-up (every 3 months) were clarified to begin after the last study clinic visit, and to allow additional timepoints at a sponsor request in preparation for interim and final analyses in order to update survival information and add uniformity in the time since most recent contact. |

Amendment 5: The purpose of this protocol amendment is to implement the External-Data Monitoring Committee (E-DMC) recommendation at the pre-specified interim analysis (section 9.6) that remaining patients on Arm B who are progression-free are offered crossover to avelumab. Also, added section 17, supplement 1: crossover from BSC alone (arm B) to avelumab plus best supportive care. This supplement provided details for arm B subjects who crossover to receive avelumab plus BSC including required eligibility criteria, general treatment or study plan, and schedule of activities for screening, treatment period, end of treatment or withdrawal and short and long term follow-up. |

Amendment 6: Following a final OS update, the frequency of study procedures was reduced while providing continued treatment for patients actively receiving avelumab and ending study participation for all patients who were not actively receiving avelumab. A new Schedule of Activities (SoA) table and a new required laboratory tests table (Table 7) were added, BICR tumor assessments were no longer performed, arm B subjects who are eligible to crossover to avelumab plus best supportive care (BSC) as per supplement 1 were permitted to do so until 60 days after the final OS update or approval of amendment 6, whichever is later and CRF data collection was reduced to those items relating to study drug exposure and adverse events. |
