This study evaluates the anti-tumor effects of ORIN 1001 in patients with advanced solid tumors or relapsed refractory metastatic breast cancer (patients with progressive disease after receiving at least two lines of therapy in the advanced setting).

Official Title

A Phase 1/2, Open Label, Dose-Escalation and Expansion Study of Oral ORIN1001 With and Without Chemotherapy in the Treatment of Subjects With Solid Tumors


This is a first in human, Phase 1/2, open label, dose escalation and dose expansion study that consists of two stages:

Phase 1: A dose escalation stage to determine the MTD/RP2D of ORIN1001 when given as a single agent in up to 30 subjects with advanced solid tumors. In addition, a dose escalation stage to determine the MTD/RP2D of daily ORIN1001 in combination with Abraxane given intravenously in up to 18 subjects with relapsed refractory metastatic breast cancer (TNBC or ER+ HER2-).

Phase 2: An expansion stage of ORIN1001 alone (Cohort A: TNBC) and in combination with Abraxane (Cohort B: Myc+; Cohort C: ER+ HER2-, and Cohort D: TNBC) to estimate efficacy in up to 120 subjects with relapsed refractory metastatic breast cancer.

Open to people ages 18 years and up

For dose escalation with ORIN1001 alone:

-Male or female with advanced solid tumors for which no effective standard of care treatments are available

For dose escalation with ORIN1001 in combination with Abraxane:

-Males or females with relapsed refractory metastatic breast cancer (TNBC or ER+, HER2-) must have progressed through at least 2 lines of therapy and for whom there are no available therapies that confer a clinical benefit

For dose expansion:

  1. Males or females with relapsed refractory metastatic breast cancer including:
  2. TNBC (i.e. estrogen receptor (ER)-, progesterone receptor-, and human epidermal growth factor receptor 2 [HER2]-)
  3. ER+ HER2- breast cancer
