Clinical Trial Summary

This is a research study to find out if a drug called belantamab mafodotin in combination with dexamethasone, a steroid, can be safely and effectively given in the community setting. Belantamab mafodotin (BLENREP) was approved in the US in August 2020 under an FDA program called accelerated approval. In November 2022, belantamab mafodotin was removed from the market because a study to further confirm its activity in relapsed/refractory multiple myeloma did not deliver a supporting result. However, this confirmatory study demonstrated that some patients may still benefit from treatment with belantamab mafodotin, and that this benefit can be long lasting. Belantamab mafodotin is often given at large academic medical centers every 3 weeks. This study will assess whether it is possible to administer belantamab in the community setting every 6 weeks. It is unknown if administering belantamab every 6 weeks versus every 3 weeks will result in improved safety and/or reduced efficacy.

Eligibility

Inclusion Criteria:

• 1. Participant must have histologically or cytologically confirmed diagnosis of MM as defined by IMWG, 2016 criteria, have had at least 4 prior therapies, and is relapsed or refractory to an anti-CD38 antibody, an IMID, and a proteasome inhibitor.

1. Refractory myeloma is defined as disease that is nonresponsive while on therapy or progresses within 60 days of last therapy. Nonresponsive disease is defined as either failure to achieve at least minimal response or development of progressive disease (PD) while on any therapy.

2. Participant must have an Eastern Cooperative Oncology Group (ECOG) performance status of = 2 3. Participant must be = 18 years of age 4. Participant must have adequate organ function, defined as follows: 5. Female participants: a. A female participant is eligible to participate if she is not pregnant or breastfeeding and at least one of the following conditions applies: i. Is not a woman of childbearing potential (WOCBP) OR ii. Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), preferably with low user dependency (as described in Appendix 3), during the intervention period and for at least 4 months after the last dose of study intervention and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during this period. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention. A WOCBP must have a negative highly sensitive serum/urine pregnancy test (as required by the protocol) within 72 hours before the first dose of study intervention. WOCBP will have pregnancy testing within 72 hours on day 1 of each cycle. The investigator is responsible for review of medical history, menstrual history, and recent sexual activity. b.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assess the feasibility of providing Belantamab mafodotin in a heavily pretreated, rural population of patients with multiple myeloma receiving this study regimen every 6 weeks instead of every 3-week cycles.	Belantamab mafodotin will be evaluated in participants with RRMM (relapsed/refractory multiple myeloma) in the community as assessed through the rate of 'unacceptable toxicity' and response rate as defined in Table 7 through all cycles	From registration until stopped early due to excess unacceptable toxicity and/or lack of efficacy. Subjects followed for 2 years from end of treatment
Secondary	Describe the efficacy of Belantamab mafodotin specifically in the elderly frail sub-population defined by the IMWG (International Myeloma Working Group) Geriatric Assessment	The score system (range 0-5), based on age, comorbidities, cognitive and physical conditions, developed by Palumbo A. et al1, identifies 3 groups of patients: Fit (score=0); Intermediate-Fitness (Score=1); Frail (Score =2)	From registration until stopped early due to excess unacceptable toxicity and/or lack of efficacy. Subjects followed for 2 years from end of treatment
Secondary	Overall Response Rate (ORR) (Full Analysis Population)	ORR was determined according to the 2016 international myeloma working group (IMWG) response criteria by IRC. ORR was calculated as the percentage of participants with a confirmed partial response (PR) or better (that is [i.e.], PR, very good partial response [VGPR], complete response [CR] and stringent complete response [sCR]). Confidence intervals were based on the exact method.	Up to 48 weeks
Secondary	Clinical Benefit Rate (CBR) by Investigator Assessment (Full Analysis Population)	CBR was determined by the investigator according to the 2016 IMWG response criteria. CBR was calculated as the percentage of participants with a confirmed minimal response (MR) or better (i.e., MR, PR, VGPR, CR and sCR). Confidence intervals were based on the exact method.	Up to 48 weeks
Secondary	Duration of Response (DoR) by Investigator Assessment (Full Analysis Population)	DoR is defined as the time from first documented evidence of PR or better until the earliest date of documented disease progression (PD) per IMWG response criteria; or death due to PD among participants who achieved an overall response, i.e., confirmed PR or better. DOR based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of DOR are presented	Up to 48 weeks
Secondary	Time to Response by Investigator Assessment (Full Analysis Population)	Time to response is defined as the time between the date of randomization and the first documented evidence of response (PR or better), among participants who achieve a response (i.e., confirmed PR or better). Time to response based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of time to response are presented.	Up to 48 weeks
Secondary	Progression Free Survival by Investigator Assessment	Progression free survival is defined as the time from enrollment until the earliest date of documented PD per IMWG, or death due to any cause. Progression free survival based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of progression free survival are presented.	Up to 48 weeks
Secondary	Time to Progression by Investigator Assessment	Time to progression is defined as the time from enrollment until the earliest date of documented PD per IMWG, or death due to PD. Time to Progression based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of time to progression are presented.	Up to 48 weeks
Secondary	Overall Survival	Overall survival is defined as the time from randomization until death due to any cause. Median and inter-quartile range (first quartile and third quartile) of overall survival are presented.	Up to 48 weeks
Secondary	Assess the safety of belantamab mafodotin in the elderly frail population for unacceptable toxicity Grade 3 or higher	The safety profile of belantamab mafodotin will be evaluated in participants with RRMM in the community as defined by the standard clinical and laboratory tests (hematology and chemistry, physical examination, vital sign measurements, and diagnostic tests) through the collection of adverse events (AEs) and serious adverse events (SAEs).	All adverse events whether serious or non-serious, will be reported from the start of treatment until 70 days after the last dose of study treatment, until the subject withdraws consent for study participation, or until the subject starts new treatment
Secondary	Corneal events will be graded according to the KVA Scale	All adverse events whether serious or non-serious, will be reported	From the start of treatment until 70 days after the last dose of study treatment, until the subject withdraws consent for study participation, or until the subject starts subsequent anticancer therapy, whichever occurs first.
