About this trial

The purpose of this study is to evaluate the safety and feasibility of a treatment holiday strategy directed by CD70-targeted immuno-PET/CT in patients with metastatic clear cell renal cell carcinoma (mccRCC). Specifically, the study aims to assess whether patients who achieve both anatomical disease control and metabolic response after 12 months of first-line PD-1/PD-L1 ICI + VEGFR-TKI combination therapy can safely pause their treatment, improve quality of life without compromising therapeutic efficacy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Male or female subjects aged ≥ 18 years

Locally advanced (not amenable to curative surgery or radiation therapy) or metastatic RCC (American Joint Committee on Cancer [AJCC] Stage IV)

Histologically or cytologically confirmed advanced RCC with predominantly clear-cell subtype

Favorable or intermediate risk as per International Metastatic RCC Database Consortium (IMDC) criteria

Disqualifiers

Prior systemic therapy for advanced RCC

Poor risk as per International Metastatic RCC Database Consortium (IMDC) criteria

Karnofsky Performance Status (KPS) <70%

Inadequate organ and bone marrow function

Trial design

Design model

Single group

Treatments tested in this trial

  • PD-1/PD-L1 ICI + VEGFR-TKI

    Drug

    All participants will receive first-line PD-1/PD-L1 inhibitor + VEGFR-TKI combination therapy for 12 months (±1 month).

  • Treatment pause

    Other intervention

    Patients who achieve the predefined criteria after 12 months of treatment will discontinue both drugs and enter a closely monitored treatment holiday. Upon radiographic or clinical progression, the previous systemic therapy will be reintroduced according to the protocol and investigator's discretion.

Trial outcomes

Primary outcomes

1

Treatment-free survival (TFS) rate

Defined as the proportion of patients who are alive without having restarted the original therapy at 12 months following discontinuation of the combination therapy.

Time frame
12 months after treatment discontinuation

Secondary outcomes

1

Overall survival (OS)

Time from enrollment to date of death due to any cause.

Time frame
From treatment initiation until 3 years of follow-up
2

Progression free survival (PFS)

Time from enrollment to first documented disease progression or death, whichever occurs first.

Time frame
From treatment initiation until 3 years of follow-up
3

Overall safety profile

Frequency and severity of adverse events (AEs) and serious adverse events (SAEs) graded by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 criteria.

Time frame
From treatment initiation until 3 years of follow-up
4

Patient-reported outcome (PRO) - Health-related quality of life measured by NCCN FKSI-19

Measured by the NCCN functional assessment of cancer therapy-kidney symptom index (FKSI-19), a 19-item scale assessing treatment-related symptoms and side effects for kidney cancer patients.

Time frame
From treatment initiation until 2 years of follow-up
