A Study to Evaluate the Safety, PK/PD of (OriCAR-017) in Subjects With RR/MM - RIGEL Study
18 - 75 Years, Male and Female
OriCAR-017 US-P1 (primary)
NCI-2024-05382
Summary
The is a first clinical study for Oricell Therapeutics Inc. in the United States to
evaluate the safety, PK, PD and preliminary efficacy of our anti-GPRC5D cell product
(OriCAR-017) in subjects with relapsed/refractory multiple myeloma.
RIGEL Study
Objectives
This is a Phase I/II, open-label multicenter study to evaluate the safety,
pharmacokinetics, pharmacodynamics, and preliminary efficacy of anti-GPRC5D CAR-T cell
product (OriCAR-017) in subjects with relapsed/refractory multiple myeloma". The study
will consist of a Phase I dose escalation stage involving three doses as a single IV
infusion) with up to 18 evaluable subjects and a dose expansion stage with 10-15
evaluable subjects, followed by a Phase II stage with up to 48 evaluable subjects.
Eligibility
- Inclusion Criteria:
Capable of giving signed informed consent
Subjects aged 18 to 75 years (inclusive) at Screening (signing the ICF).
Expected survival period is >12 weeks.
Diagnosis of MM according to the IMWG criteria (2016 version).
One of the following criteria must be met:
If immunoglobulin (Ig)G type MM, then serum M protein >10 g/L; if IgA, IgD, IgE or IgM
type MM, then serum M protein >5 g/L
Urine M protein level >200 mg/24 hour
If light chain type MM, then serum free light chain (sFLC) >100 mg/L and K/? FLC ratio is
abnormal.
Extramedullary lesions (>1 cm for diameter of the short axis).
For Phase I (dose-escalation) - Subjects who had received at least 3 prior lines of
therapy, had previous exposure to BCMA-Ag+ therapies, and were refractory to the last
line of therapy.
For Phase I (dose-expansion) and Phase II: Subjects with previous exposure to BCMA
directed therapies including BCMA bispecific antibody (e.g., teclistamab), BCMA antibody
directed conjugate (such as BLENREP), and BCMA-CAR-T (such as CARVYKT1TM)
Subjects with adequate hematologic, renal, hepatic, pulmonary and cardiac function.
Subject and partners willing to take and or use effective contraceptive measures until 2
years post IMP infusion.
Exclusion Criteria:
Pregnant or breastfeeding.
Seropositive for history of human immunodeficiency virus Active Hepatitis B infection and
or Hepatitis C infection
Known active or prior history of CNS involvement
History of autoimmune diseases (such as Crohn's disease, rheumatoid arthritis, systemic
lupus erythematosus) caused damage to terminal organs or required systemic application of
immunosuppressive or other drugs in the past 2 years
Presence of uncontrolled active infection
Subjects who received autologous hematopoietic stem cell transplantation (ASCT) within 8
weeks of Screening Visit or who plan to undergo ASCT during the study.
Subjects who received allogeneic stem cell therapy.
Any condition that in the opinion of the Investigator, would interfere with evaluation of
the IMP.
Received Bendamustine treatment 1 year prior to Screening Visit.

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts...
