About

Hope Biosciences is conducting a research study of an investigational product called Hope Biosciences autologous adipose-derived mesenchymal stem cells (abbreviated as HB-adMSCs) as a possible treatment for Rheumatoid Arthritis (RA). The study purpose is to evaluate the safety profile of a single IV infusion of HB-adMSCs in subjects with clinical diagnosis of RA.

Full description

This is a Phase 1/2a, open-label, single-dose study in subjects with active Rheumatoid Arthritis (RA). 12-15 patients will be enrolled for the study. The overall objective of this study is to evaluate the safety profile of a single IV infusion of autologous adipose-derived mesenchymal stem cells (HB-adMSCs) in subjects with clinical diagnosis of RA. The primary endpoint of this study is to measure the number and frequency of adverse event(s) and/or severe adverse event(s) throughout the study duration. The second endpoint of this study is to evaluate the ability of HB-adMSCs to alter RA-related inflammation via measuring levels of Tumor Necrosis Factor alpha (TNF-a), Interleukin-6 (IL-6), C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR) and Joint Count 66/68 after a single infusion of autologous HB-adMSCs for up to 12-month post-infusion.

Enrollment: 15 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Adult male or female between the ages of 18 and 65

• Patients have active RA as confirmed by the following criteria:

  • ≥ 6 swollen joints and ≥ 6 tender joints at screening (68-joint count)
  • Abnormal CRP result OR abnormal ESR result at screening. Abnormal CRP result at screening OR abnormal ESR defined as:
  • CRP > 4.9 mg/L or ESR > 10mm/hr for men, > 20mm/hr for women

• Patients without current established treatment, or if being treated, patients who are on a stable dose of RA therapy regimen for ≥ 4 weeks prior to screening

Exclusion criteria

• Inability to understand and provide signed informed consent

  • Pregnancy, lactation, or, if female of childbearing potential, positive serum β-hCG at screening.

  • Currently diagnosed any malignant neoplasm. Any patient who was successfully treated for cancer and has been disease-free, with no recurrence, for at least 5 years, will be considered.

  • Uncontrolled systemic illness, including, but not limited to: hypertension (systolic >150 mm Hg or diastolic >95 mm Hg); diabetes; renal, hepatic, or cardiac failure or any laboratory abnormality that poses a safety risk to the subject such as:

    • Hemoglobin ≤8.5 g/dL
    • White blood cells (WBCs) ≤3,500/mm3 (3.5 G/L)
    • Any other illness which, in the opinion of the investigator, characterizes the subject as not being a good candidate for the study

  • Participation in another study with an investigational drug or device within 4 weeks prior to treatment or 5 half-lives of the investigational product used (whichever is longer).

  • Positive results of hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B core antibody (HBcAb), hepatitis C antibody (HCV Ab), and/or human immunodeficiency virus antibody (HIV Ab) tests at screening (excluding patients who are tested positive for HBsAb alone due to a hepatitis B vaccination).

  • Positive history of Treponema pallidum.
