Last updated: March 31, 2017
Last verified: March 2017
  Purpose
The dose-confirming part of this study, comprising at least 10 patients is designed as a single center, prospective, single arm, open label in patients who have failed or are unresponsive to Azacitidine (AZA) or Decitabine (they may also have additionally failed an Erythropoiesis Stimulating Agent (ESA) followed by a dose expansion part with an additional 30 patients; the objective of the whole study being to assess the safety, efficacy, pharmacokinetics and pharmacodynamics of intravenously infused multiple doses of OPN-305 in low and intermediate-1 risk myelodysplastic syndrome (Second line Lower risk MDS).

Condition Intervention Phase
Myelodysplastic Syndrome Drug: OPN-305 Phase 1 Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Prospective, Open Label Phase I/II Study to Assess the Safety and Efficacy of Cycles of Intravenously Infused Doses of OPN-305 in Second-line Lower (Low and Intermediate-1) Risk Myelodysplastic Syndrome (MDS)

Primary Outcome Measures:
  • Establishment of the dose and dose frequency based on dose-limiting toxicity and bone marrow receptor occupancy of OPN-305 in low and intermediate -1 (Lower) risk MDS [ Time Frame: 8 weeks ]
  • Tolerability of OPN-305 as monotherapy based on adverse events [ Time Frame: 16 weeks/32 weeks (if there is no AZA add-back) ]
  • Tolerability of OPN-305 in combination with AZA based on adverse events [ Time Frame: 32 weeks ]

Secondary Outcome Measures:
  • Hematological response based on IWG06 criteria, transfusion independence and lack of progression to high risk MDS or AML [ Time Frame: wk 36 ]
  • Cytokine levels in serum (TNFα, IL-1β, IL-6, IL-10, IL-12, IL-18, IL-23 and IFN-γ) [ Time Frame: day 1 and wk 4 ]
  • Immunogenicity of OPN-305 (Measurement of anti drug antibodies and neutralizing antibodies) [ Time Frame: day 1, wks 4, 8, 16, 24 and 32 ]
  • Incidence of infections [ Time Frame: 36 weeks ]
  • Pharmacokinetic profile of OPN-305 (Cmax, tmax, AUCinf, t1/2, CL, Vd) [ Time Frame: day 1, wks 4, 8, 12, 16, 20, 24, 28, 32 ]
  • OPN-305 receptor occupancy in blood and bone marrow cells [ Time Frame: screening (bone marrow only), day 1 (blood only), wks 4 (blood only), 8, 12 (blood only), 16, 20 (blood only), 24 (blood only), 28 (blood only), 32 and 36 (blood only) ]
  • Correlation of clinical response with cytogenic data eg expression, mutational to see if clinical response given by subset [ Time Frame: wk 36 ]
  • Correlation of clinical response with QOL questionnaire feedback in terms of symptoms and severity through study completion [ Time Frame: wk 36 ]

  • If sexually active female, patient must be/have one of the following:

    • Post-menopausal defined as the absence of menses for at least one year (serum FSH ≥20IU/L can also be measured according to local practice), OR
