|Multiple Myeloma||Drug: Temferon||Phase 1 Phase 2|
This is a non-randomized, open label, single center, phase I/II, therapeutic exploratory, dose-escalation, prospective study, involving a single intravenous infusion of Temferon, an investigational advanced therapy consisting of autologous CD34+-enriched hematopoietic stem and progenitor cells (HSPCs) exposed to transduction with a third-generation, vesicular stomatitis virus-G (VSV-G) pseudo-typed lentiviral vector driving myeloid-specific interferon-ɑ2 (IFN-ɑ2) expression, which will be administered to up to 9 patients affected by multiple myeloma in early relapse after intensive front line treatment. The study will recruit, treat and follow-up patients at a specialist hematology and bone marrow transplantation unit at Ospedale San Raffaele (OSR) in Milan, Italy.
The study will enrol multiple myeloma patients that have experienced an early relapse after intensive front line treatment, have been treated with an approved second line combination treatment regimen and obtained at least a very good partial remission (VGPR) according to International Myeloma Working Group (IMWG) criteria. Once the written informed consent is obtained, and screening procedures have been completed, harvesting of HSPCs will occur. Patients will be offered maintenance treatment during Temferon production and release. Upon Temferon release for clinical use, patients will be admitted to the transplantation unit for receipt of a reduced-intensity conditioning regimen consisting of melphalan. This will be followed by autologous stem cell transplant (ASCT) and administration of Temferon. In-patient monitoring will occur until hematological recovery occurs. Thereafter, regular follow-up of patients will occur up to 2 years (+730 days). At the +730 day visit, patients will be invited to participate in a long term follow-up study which will last for an additional 6 years.
3 cohorts of 3 patients will receive escalating doses of Temferon.
In the event that MM disease progression occurs, patients will be managed according to best clinical practice.

|Official Title:||A Phase I/II Dose Escalation Study Evaluating Safety and Activity of Autologous CD34+-Enriched Hematopoietic Progenitor Cells Genetically Modified With a Lentiviral Vector Encoding for the Human Interferon-ɑ2 Gene in Multiple Myeloma Patients With Early Relapse After Intensive Front Line Therapy|
|Actual Study Start Date :||March 6, 2019|
|Actual Primary Completion Date :||April 2, 2021|
|Actual Study Completion Date :||April 2, 2021|
Autologous CD34+-enriched hematopoietic progenitor cells exposed ex vivo to a specific lentiviral vector encoding for the human IFN-ɑ2 gene.
Its expression is tightly controlled by the human TIE2 enhancer/promoter sequence and by a post-transcriptional regulation layer represented by target miRNA sequences. This enables suppression of IFN-ɑ2 expression in HSPCs, thereby further increasing the specificity of the delivery strategy for their Tie2 expressing myeloid cell progeny.
