Testing the Combination of Anetumab Ravtansine With Either Nivolumab, Nivolumab and Ipilimumab, or Gemcitabine and Nivolumab in Advanced Pancreatic Cancer

A Phase I Study of Anetumab Ravtansine in Combination With Either Anti-PD-1 Antibody, or Anti-CTLA4 and Anti-PD-1 Antibodies or Anti-PD-1 Antibody and Gemcitabine in Mesothelin-Positive Advanced Pancreatic Adenocarcinoma

This phase I trial studies the side effects and best dose of anetumab ravtansine when given together with nivolumab, ipilimumab and gemcitabine hydrochloride in treating patients with mesothelin positive pancreatic cancer that has spread to other places in the body (advanced). Anetumab ravtansine is a monoclonal antibody, called anetumab ravtansine, linked to a chemotherapy drug called DM4. Anetumab attaches to mesothelin positive cancer cells in a targeted way and delivers DM4 to kill them. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving anetumab ravtansine together with nivolumab, ipilimumab, and gemcitabine hydrochloride may work better in treating patients with pancreatic cancer.

Detailed Description

PRIMARY OBJECTIVE:

I. To evaluate the safety and tolerability of anetumab ravtansine with the following combinations in patients with mesothelin positive pancreatic adenocarcinoma.

SECONDARY OBJECTIVES:

I. To assess the preliminary anti-tumor activity of anetumab ravtansine (anetumab) in combination with nivolumab, nivolumab and ipilimumab, nivolumab and gemcitabine hydrochloride (gemcitabine) as measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 overall response rate (ORR).

II. To characterize the pharmacokinetics (PK) profile of anetumab (apparent diffusion coefficient [ADC]), total antibody (ADC and cleaved free antibody), DM4 and DM4-Me (S-Methyl metabolite of DM4).

III. To evaluate the tumor microenvironment and immune changes in tumor and peripheral blood over the course of treatment to identify predictors of response or resistance to treatment.

IV. To measure the progressive disease (PD) effects of this combination including molecular and immune biomarkers in tumor biopsies and peripheral blood.

EXPLORATORY OBJECTIVES:

I. To characterize mesothelin, PD-L1, CD3, CD4, CD8 expressions at baseline and after treatment in mesothelin positive pancreatic cancer patients.

II. To evaluate level of soluble mesothelin and megakaryocyte potentiation factor (MPF) over the course of treatment and to correlate these biomarkers with clinical outcome.

III. To perform whole exome sequencing (WES) +/- ribonucleic acid sequencing (RNAseq) in the tumor biopsy specimens and correlation genomic (e.g. mutational burden) and transcriptomic biomarkers with clinical outcome.

IV. To evaluate mononuclear phagocyte system (MPS) function, Fc-gamma receptors (FcgammaRs) and hormone and chemokine mediators as methods to evaluate factors affecting the PK and PD of these agents.

V. To evaluate anti-drug antibody (ADA) titres changes pre and post treatment and correlate them with PK, toxicity and responses.

OUTLINE: This is a dose-escalation study of anetumab ravtansine. Patients are assigned to 1 of 3 arms.

ARM I: Patients receive anetumab ravtansine intravenously (IV) over 1 hour on day 1 and nivolumab IV over 30 minutes on day 8 of cycle 1 and on day 1 of subsequent cycles. Treatment repeats every 21 or 28 days (cycle 1) for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo a biopsy and collection of blood on study.

ARM II: Patients receive anetumab ravtansine IV over 1 hour on day 1 and nivolumab IV over 30 minutes on day 8 of cycle 1 and on day 1 of subsequent cycles. Patients also receive ipilimumab IV over 30 minutes on day 8 of cycle 1 and on day 1 of cycles 2-4. Treatment repeats every 21 or 28 days (cycle 1) for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo a biopsy and collection of blood on study.

ARM III: Patients receive anetumab ravtansine IV over 1 hour on day 1 and nivolumab IV over 30 minutes on day 8 of cycle 1 and on day 1 of subsequent cycles. Patients also receive gemcitabine hydrochloride over 30-40 minutes on days 1 and 8. Treatment repeats every 21 or 28 days (cycle 1) for up to 17 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo a biopsy and collection of blood on study.

After completion of study treatment, patients are followed up every 8 weeks for up to 100 days, then every 12 weeks thereafter.

• Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of patient safety or study results
• Pregnant women are excluded from this study because of the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother, breastfeeding should be discontinued for at least 6 months after last dose of study drugs; these potential risks may also apply to other agents used in this study; should a patient become pregnant or suspect she is pregnant while she is participating in this study, the patient should inform the treating physician immediately

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum tolerated dose (MTD)	This study will follow a 3+3 dose escalation design.	Up to 30-37 days post treatment

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Biomarker analysis	The analysis on proposed biomarkers is hypothesis generating in nature. Descriptive statistics will be used for analysis of biomarkers. The key biomarker is CD8. CD8 after anetumab will be compared with CD8 after immunotherapy. Paired T-test will be carried out to identify changes in each biomarker between time points and mixed model will be used to study the trend in biomarkers over time when multiple measurements are available. The association between baseline biomarkers or change in biomarkers and clinical outcome progression-free survival, toxicity and overall response will also be analyzed by Cox model or logistic model where appropriate. The results may be adjusted using Pocock method for multiplicity.	Up to 100 days post treatment
