The purpose of this study is to assess the safety and benefits of the investigational study drug, KW-2478, when given with bortezomib (Velcade®), a drug approved for the treatment of Multiple Myeloma (MM).

The primary objectives:

* To establish the safety, tolerability, and recommended Phase II dose (RP2D) of KW-2478 in combination with bortezomib (Phase I);
* To assess the overall response rate (ORR) when subjects with advanced MM are treated (Phase II).

The secondary objectives:

* To characterize the Pharmacokinetic (PK) and Pharmacodynamic (PD) of KW-2478 with bortezomib (Phase I only);
* To evaluate for preliminary evidence of efficacy (Phase I);
* To determine progression free survival (PFS) and duration of response of KW-2478 with bortezomib (Phase II).

This is a multicenter, open label, dose escalation, Phase I / II study in subjects with relapsed and/or refractory MM. Up to 24 subjects to be enrolled in the Phase I to determine the RP2D. Up to 77 additional evaluable subjects to be enrolled in Phase II for a maximum up to 101 subjects treated in the study. Study centers in the USA and the UK will participate in Phase I and II. Centers in the Philippines will be participating in Phase II only. The planned enrollment period is 22 months and the planned study duration is 28 months.

A Study of KW-2478 in Combination With Bortezomib in Subjects With Relapsed and/or Refractory Multiple Myeloma

An Open Label, Dose Escalation, Multicenter Phase 1/2 Study of KW-2478 in Combination With Bortezomib in Subjects With Relapsed and/or Refractory Multiple Myeloma

The safety of KW-2478 was determined by reported TEAEs, observed DLTs, changes in PEs, vital sign measurements, ECGs, and laboratory analyses.

The ORR, was defined as the best response over a specified number of cycles (calculated and summarized).

Disease control rate (DCR) was defined as the best response over a specified number of cycles (calculated and summarized). Progression-free survival was defined as the time from the first day of treatment until the date of disease progression or death is first reported (calculated and summarized).

Descriptive summary statistics (number, arithmetic mean, standard deviation \[SDev\], coefficient of variation \[CV%\]) for concentration and PK data for KW-2478 and Bortezomib in Phase 1 were presented by cohort, dose level and day.

Patients treated at European Institute of Oncology with Total Body Irradiation (TBI)

Patients eligible undergoing total body irradiation as candidates for bone marrow or peripheral stem cell transplant.

Total Body Irradiation (TBI) is an oncological radiotherapy technique that has been used for several decades in patients undergoing bone marrow or peripheral stem cell transplantation.

The role of TBI is:

To suppress the recipient's immune system to prevent rejection of the donor's bone marrow, whether familial or non-familial.

To eradicate residual neoplastic cells following chemotherapy treatments.

TBI is typically employed in both neoplastic and non-neoplastic disorders affecting blood cell elements (e.g., acute and chronic leukemias, aplastic anemia, lymphomas, etc.), as well as other conditions such as neuroblastoma, Ewing's tumor, and pediatric sarcomas with a poor prognosis.

Treatment choice is usually established following multidisciplinary discussions, based on disease characteristics and stage, concurrent pathologies and pharmacological treatments, patient preferences, and functional aspects. Data collection related to radiotherapy plays a crucial role in understanding various clinical aspects of the treatment itself. The availability of data from an increasing number of patients will allow the identification of clinical situations or technical parameters of radiotherapy correlated with treatment tolerance and effectiveness, aiming to identify the best treatment for these oncological pathologies.

This project aims to collect data related to total body irradiation treatments for scientific dissemination with the goal of establishing the basis for evaluating achieved results over time and deriving from these elements useful for guiding the most effective treatment strategies and appropriate operational protocols.
