NCT ID: NCT02840994

Last Updated: 2020-02-27

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 24 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2016-12-31
• Study Completion Date: 2020-01-31

Brief Summary

The objective of the proposed clinical trial is to investigate the safety and tolerability of CV301 in combination with Anti-PD1-Therapy in subjects with non-small cell lung cancer (NSCLC).

The clinical trial is designed to evaluate the possible enhanced antitumor activity of CV301 with Anti-PD1-Therapy. The rationale for combining CV301 with Anti-PD1-Therapy is based on the hypothesis that CV301 can induce specific immune response in the tumor, and that in combination, Anti-PD1-Therapy may augment the T cell-mediated immune response generated by CV301 by blocking the inhibitory signal of the PD-1.

The trial will include a Phase 1 portion and a Phase 1b portion with 2 cohorts. The Phase 1 portion is a dose escalation part to assess the safety and tolerability of CV301 alone, prior to moving into the combination with Anti-PD1-Therapy (the Phase 1b component).

The following Phase 1b portion of the trial aims to test the safety and tolerability of the combination treatment using a two cohort approach with cohort 1 receiving CV301 plus Nivolumab and cohort 2 receiving CV301 plus Pembrolizumab.

Eligibility Criteria

Inclusion Criteria

1. Subjects must have a metastatic or unresectable locally advanced malignant solid tumor, histologically confirmed by the Laboratory of Pathology, NCI. Efforts will be made, as much as possible, to enroll subjects with tumor types with known increased expression of CEA or MUC-1 (such as lung, breast, ovarian, prostate, colorectal, pancreatic, bladder, gastric, cervix, etc.).

2. Subjects may have measurable or nonmeasurable but evaluable disease. Subjects with surgically resected or ablated metastatic disease at high risk of relapse are also eligible.

Prior therapy: Subjects must have completed or had disease progression on at least one prior line of disease-appropriate therapy for locally advanced or metastatic disease, or not be candidates for therapy of proven efficacy for their disease.

3. Subjects with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations.

4. There should be a minimum of 4 weeks from any prior chemotherapy, immunotherapy and/or radiation, with the exception of hormonal therapy for prostate and breast cancers, HER2-directed therapy for HER2+ breast cancer (3+ IHC or FISH+), maintenance therapy for colorectal or pancreatic cancer, and erlotinib therapy in EGFR-mutated lung cancer under the condition that subjects are on these therapies for at least two months before start of trial treatment. There should be a minimum of 6 weeks from any prior antibody therapies (such as ipilimumab or Anti-PD1/PDL1) due to prolonged half-life.

5. Subjects must have recovered (Grade 1 or baseline) from any clinically significant toxicity associated with prior therapy. Typically, this is 3-4 weeks for subjects who most recently received cytotoxic therapy, except for nitrosoureas and mitomycin C, for which 6 weeks is needed for recovery.

6. Men or women, age ≥ 18 years.

7. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1 or Karnofsky ≥ 70%, (see Section 19.1, Appendix I and Section 19.2, Appendix II).

8. Subjects must have normal organ and marrow function as defined below

a. Serum creatinine ≤ 1.5 x upper limit of normal (ULN) OR creatinine clearance (CrCl) ≥ 40 mL/min (if using the Cockcroft-Gault formula below): i. Female CrCl = [(140 - age in years) x weight in kg x 0.85] / [72 x serum creatinine in mg/dL] ii. Male CrCl = [(140 - age in years) x weight in kg x 1.00] / [72 x serum creatinine in mg/dL] b. Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) ≤ 3 x the ULN c. Total bilirubin ≤ 1.5 x ULN OR in subjects with Gilbert's syndrome, a total bilirubin ≤ 3.0 x ULN d. Hematological eligibility parameters (within 16 days of starting therapy): i. Platelet count ≥ 100,000/µL ii. Absolute neutrophil count (ANC) ≥ 1/ µL

9. Subjects must have baseline pulse oximetry > 90% on room air.

10. The effects of CV301 on the developing human fetus are unknown. For this reason, women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to trial entry and for the duration of trial participation and for a period of 4 months after the last vaccination. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this trial, she should inform her treating physician immediately.

11. Subjects with prostate cancer must continue to receive GnRH agonist therapy (unless orchiectomy has been done).

12. Subjects must be able to understand and be willing to sign a written informed consent document.

1. Histologically confirmed non-squamous NSCLC, metastatic or unresectable locally advanced. Actionable EGFR mutations and ALK/ROS-1 translocations targetable with FDA approved therapy must be evaluated and found not to be present by standard methods. Expression of PD-L1 must have been determined with a validated method or tumor sample must be available for PD-L1 expression determination.

2. Patient population:

• Phase 1b, Cohort 1 (Nivolumab + CV301): Patients with progression on or after prior platinum, with or without switch maintenance chemotherapy are eligible

• Phase 1b, Cohort 2 (Pembrolizumab + CV301): Patients must have been on Pembrolizumab as first-line therapy for NSCLC as per FDA approved indications in first line for at least 11 weeks and assessed by RECIST to have CR, PR, or SD at week 12 (+/- 1 week).

As of June 2017, FDA-approved indications for front-line treatment include 2 indications for Pembrolizumab:

• As a single agent for the first-line treatment of patients with metastatic NSCLC whose tumors have high PD-L1 expression (Tumor Proportion Score (TPS) ≥50%) as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations.
• In combination with pemetrexed and carboplatin, as first-line treatment of patients with metastatic nonsquamous NSCLC. This indication is approved under accelerated approval based on tumor response rate and progression-free survival. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials.

Pemetrexed single agent maintenance after the initial 4 cycles of pemetrexed in combination with carboplatinum and Pembrolizumab is allowed and optional as per investigator or institutional standard practice.

3. In case of metastatic recurrence of a previous early stage NSCLC, any chemotherapy or radiation therapy must have finalized more than 12 months before the start of the first-line treatment, either Pembrolizumab alone or in combination with pemetrexed and carboplatinum.
