Outcome measures
Primary outcome
Occurrence of Dose-Limiting Toxicity (DLT), Adverse Events (AE), and
discontinuation of study intervention due to an AE.
Objective Response (OR): Complete response (CR) or partial response (PR).
Secondary outcome
# DOR: For participants who demonstrate CR or PR, DOR is defined as the time
from the first documented evidence of CR or PR until disease progression or
death due to any cause, whichever occurs first.
# PFS: The time from the date of randomization to the date of the first
documented PD per RECIST 1.1 by BICR, or death from any cause, whichever occurs
first.
# OS: The time from the date of randomization to the date of death.
# CBR: The percentage of participants who have achieved stable disease (SD) >= 6
months or CR or PR based on assessments by BICR per RECIST 1.1.
Background summary
There were > 400.000 new cases of kidney cancer and > 175.000 deaths due to the
disease reported in 2018 worldwide. Approximately 85% of kidney tumors are
renal cell carcinoma (RCC), RCC comprises approximately 3,8% of all cancers,
and approximately 70% of these have a clear cell (cc) histology.
Since 2005, targeted therapy using VEGF-TKIs and/or anti-VEGF antibodies have
been the mainstay for the treatment of advanced RCC, and agents targeting mTOR
are also used in this setting. More recently, immune checkpoint inhibitors have
become the new revolution in treatment options.
In the EU, the recommended systemic therapy for 1L ccRCC in patients with good
risk is axitinib in combination with pembrolizumab. Alternative therapies
include sunitinib, pazopanib or tivozanib monotherapy. For patients with
intermediate or poor risk, pembrolizumab in combination with axitinib, or
ipilimumab in combination with nivolumab are recommended. Alternative therapies
for intermediate or poor risk patients include sunitinib, pazopanib or
cabozantinib monotherapy.
There have been recent advances in the treatment of 1L advanced RCC combining
immunomodulators and/or VEGF-TKI(s), and multiple agents are now available for
the treatment of patients with 2L RCC. However, existing data shows that few
patients experience CR with these agents and nearly all progress. Although
these significant advances have led to a change in the treatment paradigm of
these patients, there remains an unmet need to improve outcomes for both 1L and
2L+ advanced RCC populations.
Advanced 1L RCC has historically been resistant to anticancer therapies;
however, with the arrival of new therapies including immune-checkpoint-based
immunotherapy (CTLA-4 and
PD-[L]1 inhibitors) in combination with a VEGF-TKI, OS in this population has
significantly improved. Although several mechanisms have been proposed to
explain resistance to PD-1 inhibition including insufficient antitumor T-cell
generation, inadequate antitumor T-cell effector function, or impaired T-cell
memory, the exact mechanism remains unknown. Thus, the goal of evaluating
combination strategies in this setting is to improve the overall outcome of
patients with 1L RCC.
Study objective
This study has been transitioned to CTIS with ID 2023-506838-68-00 check the CTIS register for the current data.
Primary objectives:
# Safety Lead-in Phase: To assess the safety and tolerability, and to establish
an RP2D if applicable, of treatment combinations that have not been evaluated
in a separate study.
# Efficacy Phase: To assess the safety and tolerability of each treatment arm
based on the proportion of participants with AEs.
# Efficacy Phase: To evaluate objective response rate (ORR) of each treatment
arm as assessed by Blinded Independent Central Review (BICR) per RECIST 1.1.
Secondary objectives (all in Efficacy Phase):
# To evaluate the duration of response (DOR) as assessed by BICR per RECIST 1.1.
# To evaluate progression free survival (PFS) as assessed by BICR per RECIST
1.1.
# To evaluate overall survival (OS).
# To evaluate clinical benefit rate (CBR) per RECIST 1.1 as assessed by BICR.
Study design
Substudy MK3475-03A from Umbrella research protocol MK3475-U03 is a phase 1b/2,
rolling arm, multicenter, open-label adaptive design study that evaluates the
safety and efficacy of multiple experimental arms for the treatment of advanced
ccRCC in subjects who have not received prior systemic therapy for advanced RCC.
This substudy is composed of a specific set of treatment arms, and these arms
are composed of combinations of investigational products (IPs). More IP(s) will
be added to the Efficacy Phase of this study after an initial evaluation of
safety and tolerability of the IP(s) has been completed in a separate study or
in the Safety Lead-in Phase of this study.
Intervention
This study has 4 intervention groups with different IP combinations. The
subjects receive 1 of these IV (intravenous infusion) treatments: pembrolizumab
or MK-1308A (quavonlimab + pembrolizumab) or MK-7684A (vibostolimab +
pembrolizumab) for up to 2 years, either 3-weekly or 6-weekly. The subjects
also receive oral treatment (daily) with lenvatinib and/or belzutifan until
disease progression or unacceptable toxicity.
Study burden and risks
By participating in this study, participants will be exposed to invasive
procedures (e.g. biopsy collection, blood collection and CT- or MRI-scans), are
asked to visit the hospital regularly, and receive experimental therapy with
potentially serious side effects. It is unsure if the participants will
directly benefit from the study intervention.
The treatment depends on the group the participant is assigned to. Some of the
treatments have been administered to a large number of oncology patients
(various indications) with a known safety profile. Other treatments have
recently been developed and were administered to < 1.000 participants in
previous studies. All known side effects are included in the written
information provided to the participants, including the expected frequency of
occurrence.
In general, participants must be informed on the nature and extent of the
burden and risks associated with participation, as well as the potential
benefit, by means of the patient information sheet and the explanation from the
investigator.
