A Phase 1 interventional study of Biopsy Procedure and Biospecimen Collection in Clinical Stage IV Cutaneous Melanoma AJCC v8, Metastatic Colorectal Carcinoma and Metastatic Malignant Solid Neoplasm, sponsored by National Cancer Institute (NCI). Active, not recruiting at 9 sites in 2 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-07.
Sponsored by National Cancer Institute (NCI) · Phase 1, Interventional, and Treatment
This phase I trial studies the side effects and best dose of ziv-aflibercept when given together with pembrolizumab in treating patients with solid tumors that that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Ziv-afibercept works by decreasing blood and nutrient supply to the tumor, which may result in shrinking the tumor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving ziv-aflibercept together with pembrolizumab may be a better treatment for patients with advanced solid tumors.
PRIMARY OBJECTIVE:
I. To determine the safety, tolerability and recommended phase II dosing for the combination of ziv-aflibercept plus MK-3475 (pembrolizumab) in patients with unresectable stage III or stage IV melanoma, renal cell cancer, ovarian cancer, colorectal cancer, or sarcoma.
SECONDARY OBJECTIVES:
I. To obtain preliminary estimates of progression-free survival at 6 months. II. To obtain preliminary estimates of the rate of 1-year overall survival. III. To obtain preliminary estimates of the response rate. IV. To obtain preliminary estimates of time to progression. V. To perform correlative sciences that provide information regarding the mechanisms of action for this combination treatment.
OUTLINE: This is a dose-escalation and dose expansion study of ziv-aflibercept.
Patients receive pembrolizumab intravenously (IV) over approximately 30 minutes and ziv-aflibercept IV over 1-2 hours on day 1. Cycles repeat every 2 weeks for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scan, magnetic resonance imaging (MRI), blood sample collection and tumor biopsy throughout the study.
After completion of study treatment, patients are followed up for at least 12 weeks.
5,599 studies on the registry are indexed under Colorectal Neoplasms; 1,459 are open to participants now.
This study's enrollment of 59 is below the median of 77 across 4,123 interventional studies indexed under Colorectal Neoplasms.

Recommended combination dose of ziv-aflibercept and pembrolizumab
Will be assessed by dose-limiting toxicities. Safety will be evaluated for all treated patients using the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. All adverse events recorded during the trial will be summarized and presented by dose level. For patients enrolled in the dose expansion phase of the trial, adverse events summaries will also be summarized according to disease cohort. The proportion of patients with grade-3 or higher adverse events will be presented with 90% exact binomial confidence interval.
Time frame: 4 weeks
Objective response rate (ORR)
The ORR will be the proportion of patients achieving complete or partial response as their best response to therapy. The analysis will be descriptive and will be used to assess for early indications of efficacy. Will be summarized by disease type and in the aggregate, if appropriate. ORR will be estimated and will be summarized with 90% confidence intervals estimated using exact binomial methods.
Time frame: Between the date of first dose of trial therapy and the date of objectively documented disease progression or cessation of trial therapy, whichever occurs first, assessed up to 12 weeks
Progression-free survival
The analysis will be descriptive and will be used to assess for early indications of efficacy. Will be summarized by disease type and in the aggregate, if appropriate. Will be summarized using the product-limit method of Kaplan-Meier; 90% confidence intervals will be based on log(-log\[outcome\]) methodology.
Time frame: Time from start of trial treatment until objective disease progression (per RECIST) or death, whichever occurs first, assessed up to 6 months
Overall survival
The analysis will be descriptive and will be used to assess for early indications of efficacy. Will be summarized by disease type and in the aggregate, if appropriate. Will be summarized using the product-limit method of Kaplan-Meier; 90% confidence intervals will be based on log(-log\[outcome\]) methodology.
Time frame: Time from start of trial treatment to death from any cause, assessed up to 12 months
Time-to-progression
The analysis will be descriptive and will be used to assess for early indications of efficacy. Will be summarized by disease type and in the aggregate, if appropriate. Will be summarized using the product-limit method of Kaplan-Meier; 90% confidence intervals will be based on log(-log\[outcome\]) methodology.
Time frame: Time interval between the dates of the start of trial treatment and first documentation of progressive disease, assessed up to 12 weeks
Phenotype changes in cell populations
