Melanoma Clinical Trial

Phase I-Ib/II Study of MBG453 as Single Agent and in Combination With PDR001 in Patients With Advanced Malignancies

Summary

The purpose of this first-in-human study of MBG453 was to characterize the safety, tolerability, pharmacokinetics, pharmacodynamics and anti-tumor activity of MBG453 administered i.v. as a single agent or in combination with PDR001 or decitabine in adult patients with advanced solid tumors

Full Description

This study was a first in human (FIH), open-label, Phase I-Ib/II, multi-center study which consisted of a Phase I dose escalation part of sabatolimab (MBG453) as single agent, and a Phase Ib dose escalation part of sabatolimab in combination with spartalizumab (PDR001) that commenced after two cohorts in the dose escalation with single agent were completed. Once the maximum tolerated dose (MTD)/recommended Phase II dose (RP2D) of sabatolimab as single agent and in combination with spartalizumab was achieved, a dose ranging part and a Phase II part started.

• Phase I dose escalation part (sabatolimab single agent): In the Phase I part of the study, cohorts of subjects were treated with sabatolimab as single agent either every 2 weeks (Q2W) or every 4 weeks (Q4W) until the MTD was reached or a lower RP2D was established.

The sabatolimab single agent dose escalation part in Japan ran separately in order to ensure that the safety and pharmacokinetics (PK) profiles of single-agent sabatolimab are adequately characterized in Japanese patients. If the recommended dose of single agent sabatolimab in Japanese patients was the same as in the rest of the world (ROW) patients, then patients enrolled in Japan were to be recruited into the other parts of the study.

• Phase Ib dose escalation part (sabatolimab in combination with spartalizumab): The combination Phase Ib part of the study was to be commenced after at least two cohorts of sabatolimab as single agent were completed, and safety data suggested acceptable toxicity for subjects to begin treatment in combination. Following identification of the MTD/RP2D for the combination of sabatolimab and spartalizumab with a Q2W dosing schedule, a further dose escalation was planned to identify the MTD/RP2D with a Q4W dosing schedule.

The sabatolimab in combination with decitabine treatment arm (Phase Ib) was not opened for enrollment.

Dose ranging part: During the dose ranging part various dose levels of single agent sabatolimab were tested to better understand the safety, tolerability and PK.
Phase II part (sabatolimab in combination with spartalizumab): Once the MTD and/or RP2D were declared for sabatolimab in combination with spartalizumab, additional subjects were enrolled in the Phase II part in the selected indications (melanoma and non-small cell lung carcinoma) in order to assess the preliminary anti-tumor activity.

The Phase II single agent sabatolimab treatment arm was not opened for enrollment.

Eligibility Criteria

Inclusion Criteria:

Histologically documented advanced or metastatic solid tumors.
Phase I-Ib part (including dose ranging part): Patients with advanced/metastatic solid tumors, with measurable or non-measurable disease as determined by RECIST v1.1, who have progressed despite standard therapy or are intolerant of standard therapy, or for whom no standard therapy exists and who did not receive prior anti-PD-1/PD-L1 treatment.
Phase II part (MBG453 single agent): Patients with advanced/metastatic solid tumors in the indication in which at least one confirmed PR or CR was seen during the dose escalation phase I part. Patients must have measurable disease as determined by RECIST v1.1, have progressed despite standard therapy or be intolerant to standard therapy.

Phase II part (MBG453 in combination PDR001): Patients with advanced/metastatic tumors in the below selected indications, with at least one measurable lesion as determined by RECIST v1.1, who have received standard therapy and are intolerant of standard therapy or have progressed following their last prior therapy.:

Melanoma (anti-PD-1/PD-L1 therapy naïve or pre-treated)
Non small cell lung cancer (anti-PD-1/PD-L1 therapy naïve or pre-treated)
Renal Cell Carcinoma (anti-PD-1/PD-L1 therapy naïve or pre-treated)
Must have a site of disease amenable to biopsy, and be a candidate for tumor biopsy according to the treating institution's guidelines. Patient must be willing to undergo a new tumor biopsy at screening/baseline, and during therapy on the study.
For MBG453 in combination with decitabine: anti-PD-1/PD-L1 therapy naïve SCLC patients who have failed no more than two lines of standard chemotherapy including topotecan

Exclusion Criteria:

Presence of symptomatic central nervous system metastases.
History of severe hypersensitivity reactions to other monoclonal antibodies.
Human Immunodeficiency Virus, Hepatitis B Virus or Hepatitis C Virus infection.
Active autoimmune disease or a documented history of autoimmune disease, including ulcerative colitis and Crohn's disease or any condition that requires systemic steroids.
Systemic steroid therapy or any immunosuppressive therapy (≥10mg/day prednisone or equivalent).
Use of any vaccines against infectious diseases (e.g. varicella, pneumococcus) within 4 weeks of initiation of study treatment.
Pre-treatment with anti-CTLA4 antibodies in combination with any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathway.
Participation in an interventional, investigational non-immunotherapy study within 2 weeks of the first dose of study treatment.
Prior participation in an interventional, investigational cancer vaccine or immunotherapy study except for an anti-PD-1/PD-L1 study.
For MBG453 in combination with decitabine: Hypersensitivity to decitabine or to any of the excipients, listed in decitabine country specific label
