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.

Criteria for eligibility:
Criteria:
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. Nonchildbearing potential is defined as follows: i. Premenarchal ii. Premenopausal female with ONE of the following: 1. Documented hysterectomy 2. Documented bilateral salpingectomy 3. Documented bilateral oophorectomy 4. Documented post-tubal ligation surgery 5. For individuals with permanent infertility due to an alternate medical cause other than the above, (e.g., mullerian agenesis, androgen insensitivity), investigator discretion should be applied to determining study entry. a. Note: Documentation can come from the site personnel's: review of participant's medical records, medical examination, or medical history review iii. Postmenopausal female 1. A postmenopausal state is define as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy (HRT). However, in the absence of 12 months of amenorrhea, confirmation with more than one FSH measurement is required. 2. Females on HRT and whose menopausal status is in doubt will be required to use of the non-estrogen hormonal highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment. 6. Male participants: Male participants are eligible to participate if they agree to the following during the intervention period and for 6 months after the last dose of study treatment to allow for clearance of any altered sperm: 1. Refrain from donating sperm PLUS, either 2. Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent. OR c. Must agree to use contraception/barrier as detailed below: i. Agree to use a male condom, even if they have undergone a successful vasectomy, and female partner to use an additional highly effective contraceptive method with a failure rate of <1% per year as when having sexual intercourse with a woman of childbearing potential (including pregnant females). 7. All prior treatment-related toxicities (defined by National Cancer Institute- Common Toxicity Criteria for Adverse Events (NCI-CTCAE), version 5.0) must be ≤ Grade 1 at the time of enrollment except for alopecia or at a stable baseline for at least 6 weeks. 8. Participant must be able to understand the study procedures and agree to participate in the study by providing written informed consent 9. Participant must agree to not wear contact lenses while on the study 10. Participant must agree to have a detailed eye exam by an eye care specialist prior to each treatment of Belantamab mafodotin and agree to use preservative-free lubricant eye drops at least 4 times every day while on treatment Exclusion Criteria: - 1. Participant must not have current corneal epithelial disease except mild changes in corneal epithelium 2. Participant must not have current unstable liver or biliary disease defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, persistent jaundice, or cirrhosis. NOTE: Stable non-cirrhotic chronic liver disease (including Gilbert's syndrome or asymptomatic gallstones) or hepatobiliary involvement of malignancy is acceptable if otherwise meets entry criteria 3. Participant must not have presence of active renal condition (infection, requirement for dialysis or any other condition that could affect participant's safety). Participants with isolated proteinuria resulting from MM are eligible, provided they fulfil inclusion criteria 4. Participant unwilling to forego use of contact lenses while participating in this study 5. Participant must not be simultaneously in any other therapeutic clinical trial without permission of the Sponsor 6. Participant must not have used an investigational drug or approved systemic anti-myeloma therapy (including systemic steroids) within 14 days or five half-lives, whichever is shorter, preceding the first dose of study drug and to have recovered from any drug-related drug toxicity to at least Grade 1 7.
