Ulixertinib and Palbociclib in Treating Patients with Advanced or Refractory Solid Tumors or Metastatic Pancreatic Cancer

Trial Status: Active

This phase I trial studies the side effects and best dose of ulixertinib and palbociclib and to see how well they work in treating patients with solid tumors that have spread to other places in the body or do not respond to treatment or pancreatic cancer that has spread to other places in the body. Ulixertinib and palbociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

  • Unable or unwilling to discontinue use of any drug known to be a sensitive CYP3A4 substrate with a narrow therapeutic index
  • Known metastases of the central nervous system (CNS)
  • Any important medical illness or abnormal laboratory finding that would increase the risk of participating in the study (based on the investigator’s judgment)
  • Psychiatric illness/social situations that would limit compliance with study requirements

PRIMARY OBJECTIVES:

I. To estimate the maximum tolerated dose (MTD) and determine the recommended phase 2 dose (RP2D) of ulixertinib in combination with palbociclib in patients with advanced solid tumors. (Dose escalation)

II. To estimate overall survival (OS) at 6 months after treatment with the RP2D of ulixertinib in combination with palbociclib in an expansion cohort of patients with metastatic pancreatic cancer. (Expansion cohort)

SECONDARY OBJECTIVES:

I. To characterize the safety profile of ulixertinib in combination with palbociclib.

II. To estimate objective response rate (ORR) after treatment with ulixertinib in combination with palbociclib.

III. To estimate progression-free survival (PFS) after treatment with ulixertinib in combination with palbociclib.

IV. To estimate OS after treatment with ulixertinib in combination with palbociclib (expansion cohort only).

V. To estimate CA19-9 response after treatment with ulixertinib in combination with palbociclib (expansion cohort only).

EXPLORATORY OBJECTIVES:

I. To characterize the pharmacokinetics (PK) profile of ulixertinib when administered alone and to characterize the PK profile of both ulixertinib and palbociclib when taken concomitantly.

II. To explore differential kinome activation before and after the first cycle of treatment with ulixertinib in combination with palbociclib in patients with metastatic pancreatic cancer in the expansion cohort.

III. To correlate pancreatic cancer subtypes via ribonucleic acid sequencing (RNAseq) with clinical outcomes from archived samples in patients with metastatic pancreatic cancer in the expansion cohort.

IV. To evaluate protein expression to determine potential predictive biomarkers of response and resistance to treatment with ulixertinib in combination with palbociclib in patients with metastatic pancreatic cancer in the expansion cohort.

OUTLINE: This is a dose-escalation study.

Patients receive ulixertinib orally (PO) twice daily (BID) on days 1-28 and palbociclib PO once daily (QD) on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for 2 years.
