Trial summary

This study will assess the immunomodulatory activity of entinostat in patients with advanced renal cell carcinoma receiving the PD-L1 inhibitor atezolizumab. The overall hypothesis is that entinostat will increase the immune response and anti-tumor effect induced by the PD-L1 inhibition by suppressing Treg function. Read more about this study

About this study

Official title: A Phase I/II Study to Evaluate the Safety, Pharmacodynamics and Efficacy of Atezolizumab in Combination With Entinostat and Bevacizumab in Patients With Advanced Renal Cell Carcinoma

This study will assess the immunomodulatory activity of entinostat in patients with advanced renal cell carcinoma receiving the PD-L1 inhibitor atezolizumab. The overall hypothesis is that entinostat will increase the immune response and anti-tumor effect induced by the PD-L1 inhibition by suppressing Treg function. We have chosen renal cell carcinoma that has been reported to respond to PD1/PD-L 1 inhibition. The schedule of entinostat is based on our previous experience with this agent. Based on our working hypothesis that low dose HDAC inhibitors will have a suppressive function on Tregs but not on T effector cells, the starting dose of entinostat will be 1 mg and will be escalated up to 5 mg rather than the 10 mg dose. The combination also with bevacizumab will provide an effective VEGF inhibition that may potentiate the immune response and anti-tumor effect induced by atezolizumab. The proposed dose and schedule for atezolizumab and bevacizumab has been shown to be well tolerated in prior Phase/I/II studies and is currently tested in a Phase III randomized study in patients with renal cell carcinoma with sunitinib as a control arm. The highest proposed dose level for entinostat (5 mg) represents 50% of the recommended Phase II dose for this compound as a single agent.

Read the detailed description

This is a Phase l/II, open-label, safety, pharmacodynamics and efficacy study of atezolizumab in combination with entinostat and bevacizumab in patients with advanced renal cell carcinoma. This clinical study will be composed of a Dose Finding Phase (Phase I) and a two-stage Phase (Phase II) portion.

In Phase 1 Combination Phase), patients will be treated with oral entinostat every 7 days, with bevacizumab at the fixed dose of 15 mg/kg IV every 3 weeks and with atezolizumab at the fixed dose of 1200 mg IV every 3 weeks. Each cycle length is 21 days. Three dose levels of entinostat will be tested in 3-design patient cohorts according to the 3 + 3 standard design (1 mg, 3 mg and 5 mg). For the Dose Finding Phase, the starting dose level of pill be 1 mg by mouth every 7 days. The first dose level will have a minimum of 3 patients treated (unless the first 2 patients experience DLT(s) before the 3rd patient is enrolled). DLTs attributable to entinostat and/or bevacizumab and/or atezolizumab will be evaluated during the first 21 days of the combination treatment.

If a DLT occurs in 1 patient treated at the starting dose level, a minimum of 3 additional patients will be treated at this dose level. If DLTs occur in 2 or more of the first 6 patients, the study will be terminated. If a DLT occurs in 1 out of 6 patients, 3 additional patients will be treated at the next dose level (level 2). If no DLTs occur at the starting dose level 1, 3 additional patients will be treated at the next dose level (level 2). If no DLTs occur at the dose level 2, 3 additional patients will be treated at the next dose level (level 3). If no DLTs occur at dose level 3, this dose level will be recommended for the Phase II portion of the study. Patients who experience Grade ≥ 3 toxicity and recover to ≤ Grade 1 (or to pretreatment baseline level toxicity) may continue treatment at the next lower level. The Phase II Dose will be RP2D of entinostat (i.e., the highest tested dose that is declared safe and tolerable by the Investigators and Sponsor-Investigator).

Once the RP2D is identified, the Phase II portion (Simon's two stage design) will be opened. During Phase II, Cohorts A and B will have a Run-In period with entinostat for one cycle followed by atezolizumab and bevacizumab for the second cycle, and then the Combination Phase. The reason for the Run-In period is to obtain data on the immunomodulatory effects of entinostat separately from bevacizumab and atezolizumab. The run-in period will be optional for patients, including those who are rapidly progressing, or if it is in the patient's best interest clinically as determined by the treating physician's discretion. In Stage I, 27 patients with prior treatments will be enrolled in two Phase II cohorts: 18 treatment naïve (anti-PD1/PDL1 naïve) patients (Cohort A), and 9 anti-PD1 resistant (defined as patients who have been on PD1 inhibitors for at least 3 months and have progressed by either clinical or radiographic assessment) patients (Cohort B). If ≥ 5 responses are observed and confirmed in Cohort A, Stage II will be conducted with 15 additional patients. In Cohort B, if any patients has a response that is observed and confirmed, Stage II will be conducted with 7 additional patients. Patients will be treated on Cohort B with the same combination therapy as in Cohort A.

Cohort B is a pilot arm which aims to test atezolizumab in anti-PD1 resistant patients. If there is no response to atezolizumab, then the RP2D dose of entinostat will be added to the standard dose of atezolizumab. If there is a response to atezolizumab, patients will continue to be treated with atezolizumab alone.

The RP2D is the dose of entinostat, atezolizumab, and bevacizumab in combination chosen for further clinical development. Further experience in the Dose Expansion Cohort may result in a RP2D dose lower than the MTD.

Objectives:

  1. Primary Phase I: To assess the safety and tolerability of atezolizumab in combination with entinostat and bevacizumab in patients with advanced renal cell carcinoma.
  2. Primary Phase II: To assess the objective response rate of atezolizumab in combination with entinostat and bevacizumab in anti-PD 1 naïve patients and atezolizumab in combination with entinostat in anti-PD 1 resistant patients with advanced renal cell carcinoma.
  3. Secondary: To assess the objective response rate (Phase I only), progression-free survival and overall survival.
  4. Correlative: To characterize PD-L1/2, immune cell subsets, and miRs in tumor and/or blood in correlation with response.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase I: Recommended Phase II Dose of Entinostat

    Three dose levels of entinostat (1 mg, 3 mg and 5 mg) were tested according to the 3 + 3 standard design. The starting dose level of entinostat was 1 mg orally every 7 days. DLTs attributable to entinostat and/or bevacizumab and/or atezolizumab were evaluated during the first 21 days of the combination treatment.

    If a DLT occurs in 1 patient treated at the starting dose level, a minimum of 3 additional patients will be treated at this dose level. If DLTs occur in 2 or more of the first 6 patients, the study will be terminated. If a DLT occurs in 1 out of 6 patients, 3 additional patients will be treated at the next dose level (level 2). If no DLTs occur at the starting dose level 1, 3 additional patients will be treated at the next dose level (level 2). The process is repeated for dose level 2. If no DLTs occur at dose level 3 or if 1 DLT occurs out of 6 patients, then this dose level will be recommended for the Phase II portion of the study.

    Measured: 21 days

  2. Phase II: Percentage of Patients With Objective Response

    Percentage of patients who achieved a complete response or partial response to treatment as measured per RECIST 1.1.

    Complete response: Disappearance of all target lesions. Partial response: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter.

    Measured: Up to 1 year

Secondary outcomes (3)

  1. Phase I: Percentage of Patients With Objective Response

    Percentage of patients who achieved a complete response or partial response to treatment as measured per RECIST 1.1.

    Complete response: Disappearance of all target lesions. Partial response: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter.

    Measured: Up to 1 year

  2. Phase II: Median Progression-free Survival

    Progression free survival was defined as the time from on treatment date to date of recurrence of any type or death from any cause. Patients who did not experience recurrence or death were censored at their last evaluation date. The Kaplan-Meier method was used to determine the median and 95% confidence interval.

    Measured: Up to 4.5 years

  3. Phase II: Median Overall Survival

    Overall survival was defined as the time from on treatment date to death due to any cause. Patients who remained alive were censored at their last known alive date. The Kaplan-Meier method was used to determine the median and 95% confidence interval.

    Measured: Up to 5.5 years

What is this clinical trial studying?

A Phase 1/2 study testing Atezolizumab, Bevacizumab and Entinostat in people with Metastatic Cancer and Renal Cancer, run by Roberto Pili at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 92 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase I: Recommended Phase II Dose of Entinostat (time frame: 21 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03024437.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2025; AzTrials last refreshed its copy on 8 Nov 2026.
