R&D Update

HDP-101 Phase I/II study in Multiple Myeloma patients

Multiple Myeloma (MM) is a type of blood cancer

  • that develops from plasma cells in the bone marrow and can affect more than one part of the body

  • In myeloma, the bone marrow makes lots of abnormal (cancerous) plasma cells.

  • Worldwide incidence of multiple myeloma is currently 160,000 with a mortality of 106,000.

Phase I part is making good progress

  • Five patient cohorts (20, 30, 60, 80 and 100 µg/kg) completed

    • 18 patients in total

    • Treatment was safe and well-tolerated in the first four cohorts

    • 1 patient in stable disease on monotherapy for > 1 year from cohort 3

  • Cohort 5:

    • First efficacy: 3 objective responses at dose level 100 µg/kg,

    • 3 partial remissions out of 5 patients treated continuously with 100µg/kg

    • Safety Review Committee recommended dose optimization to increase tolerability

    • Initial reduction of thrombocyte count addressed by planned modification and optimization of the medication regimen (protocol amendment) in Cohort 6
