The purpose of this study is to establish the recommended Phase 2 dose (RP2D), safety, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antitumor activity of ORIC-101 in combination with other anticancer therapies when administered to patients with advanced or metastatic solid tumors.

Official Title

An Open-label Phase 1b Study of ORIC-101 in Combination With Anticancer Therapy in Patients With Advanced or Metastatic Solid Tumors


ORIC-101 is a small molecule GR antagonist being developed for the treatment of patients with solid tumor malignancies. Mechanistically, ORIC-101 inhibits GR transcriptional activity and blocks the pro-survival signals mediated by the activated nuclear receptor.

This is an open-label, uncontrolled, multicenter, dose-finding study to assess the safety and preliminary antitumor activity of ORIC-101 in combination with anticancer therapy in patients with advanced or metastatic solid tumors. The study will begin with dose finding in combination initially with nab-paclitaxel; additional dose-finding cohorts with other anticancer therapies may be evaluated through protocol amendment(s).

The study will first evaluate intermittent administration (5 days on, 2 days off for 21 days) of ORIC-101 followed by continuous administration (daily for 21 days) in combination with nab-paclitaxel using a standard 3+3 dose escalation design.

Dose expansion may further evaluate the safety of ORIC-101 at a dose selected from dose escalation.

Open to people ages 18 years and up

  • Advanced or metastatic solid tumor, with the exception of neuroendocrine tumors that secrete adrenocorticotropic hormone (ACTH) or corticotropin-releasing hormone (CRH), for which no alternative effective standard therapy is available or for which standard therapy is considered unsuitable or intolerable
  • Measurable disease (ie, presenting with at least one measurable lesion per RECIST 1.1)
  • Radiographic evidence of a lesion that may be safely biopsied by core needle biopsy
  • For patients with treated, stable CNS metastases that are asymptomatic: no evidence of progression for at least 4 weeks after CNS-directed treatment as determined by clinical examination and brain imaging. Patients must not require steroids
