Brief summary
The study aims to determine the efficacy of combination therapy with Carfilzomib and Dexamethasone and Belantamab mafodotin (BelaMaf-Kd) for patients with relapsed refractory multiple myeloma. Belantamab mafodotin is a new drug which has not been approved for use by the Therapeutic Goods Administration and so this combination is considered an experimental treatment. Who is it for? You may be eligible to participate in this trial if you are aged 18 years or over, and have received between 1 to 3 prior lines of therapy for multiple myeloma but have not undergone allogeneic stem cell transplantation. Study Details Eligible participants will receive 6 cycles of combination BelaMafKd with treatment given over a 28 day cycle as tolerated. Belantamab mafodotin and Carfilzomib will be delivered by IV infusion on days 1 and 8 and days 1, 8 and 15 respectively. Dexamethasone will be given orally weekly. Participants will be required to have blood samples taken and medical reviews (including ophthalmic examination) at the beginning of each cycle. An ultrasound test of cardiac function will be performed at screening and within 2 weeks of completion of cycle 6. A bone marrow biopsy will be performed at screening, at cycle 6 and to confirm a complete response or disease progression. These assessments will enable researchers to monitor whether the treatment is safe and whether it is effectively treating the myeloma. Study treatments will be halted if participants show disease progression, unacceptable toxicity, or upon withdrawal of consent. A final medical assessment and ophthalmic exam will be performed at end of treatment, with follow up to continue every 12 weeks until one year after the final cycle of treatment. Follow up assessments will continue every 12 weeks until one year after the final cycle of treatment. It is hoped that the findings of this trial will establish the benefits of Belantamab mafodotin in combination with Carfilzomib and Dexamethasone for the treatment of patients with early relapsed multiple myeloma.
Interventions
This is a phase I/II open label single arm clinical study. Patients with relapsed refractory multiple myeloma who have had 1 to 3 prior lines of treatment, will receive Belantamab Mafodotin in combination with carfilzomib and dexamethasone ("BelaMaf-Kd") over alternating treatment cycles of 28 days as follows: Belantamab mafodotin will be given intravenously over 30 minutes to 1 hour at 2.5mg/kg on day 1 of cycle 1, then on day 1 of every second cycle, i.e. 8 weekly. It will be administered first (ahead of Carfilzomib) followed by a 1 hour rest period. Carfilzomib will be infused in a 50 -100ml intravenous bag over 30 minutes on day 1, cycle 1 at 20mg/m2, then at 70mg/m2 on days 1, 8 and 15 each cycle onwards. The administration of carfilzomib is as per institutional guideline. Carfilzomib will be administered after Belantamab Mafodotin provided the patient is clinically stable. Dexamethasone 40mg (20mg for patients aged > 75) will be given orally weekly, on days 1, 8, 15 and 22. There will be two phases in the study. The first, safety, run-in phase will consist of 10 patients. After the 10th evaluable patient has completed the 1st cycle, all toxicities that occur will be summarised by worst grade and association with the study treatment. The trial management committee (TMC) will hold a meeting to assess whether or not there are any safety concerns at that dosing schedule. Provided that no more than 3 patients experience a grade 4, treatment-emergent toxicity, and subject to the confirmatory advice from the Data and Safety Monitoring Committee (DSMC), the expansion phase will commence at the same treatment dose and schedule. If 4 or more patients experience grade 4 toxicities, accrual will be paused and the safety ‘run in’ phase repeated at a dose reduction, with the same guidelines for expansion applied. In the expansion phase, alternating BelaMaf-Kd and Kd treatment will continue as long as tolerated, or until patient withdraws consent or disease progresses. Dose level reductions and delays in delivery apply for each therapy based on grade of symptoms and toxicities, and upon medical review. If any of the treatments are stopped as intolerable, the other treatments may continue. Participants will be assessed within 7 days prior to starting each cycle for adverse events, according to CTCAE-NCI v5.0 and by physical examination, including weight and ECOG performance status, blood analysis, including myeloma markers and liver function, urinalysis, and evaluation of myeloma response according to the International Myeloma Working Group definition criteria. Bone marrow biopsy will be performed at screening and within 2 weeks of completion of cycle 6, and to evaluate complete response or disease progression Ocular examination will be performed at screening and day one of each cycle, at end of treatment and for > grade 2 symptoms) Transthoracic Cardiac Echocardiogram will be performed to assess left ventricular ejection fraction at screening and within 2 weeks of completion of cycle 6, and upon grade 3 dyspnoea or at the investigators discretion during symptoms of cardiac failure.
This is a phase I/II open label single arm clinical study. Patients with relapsed refractory multiple myeloma who have had 1 to 3 prior lines of treatment, will receive Belantamab Mafodotin in combination with carfilzomib and dexamethasone ("BelaMaf-Kd") over alternating treatment cycles of 28 days as follows: • Belantamab mafodotin is given as an infusion (injection into the vein) over between 30 minutes to 1 hour. o Cohort 1- once every 8 weeks. That is, on cycle 1 day 1, and then day 1 of every second cycle i.e. cycle 3 day 1, cycle 5 day 1. The dosage will be calculated at 2.5 milligram per kilogram (mg/kg) of your body weight. o Cohort 2 - once every 12 weeks. That is, on cycle 1 day 1, cycle 3 day 1 and then day 1 of every third cycle i.e. cycle 6 day 1, cycle 9 day 1. The dosage will be calculated at 1.9 milligram per kilogram (mg/kg) of your body weight. • Carfilzomib is administered as an infusion over 30 minutes on days 1, 8, and 15. The first dose on day 1 of cycle 1 is given at a lower dose. • Dexamethasone is a medication given by mouth (40mg) once a week on days 1, 8, 15 and 22 of the 28 day cycle. Recruitment for cohort 1 was completed in August 2023 and cohort 2 is currently open for recruitment.
