Introduction Multiple myeloma (MM) is a clonal plasma cell malignancy and is the second most common type of hematologic cancer worldwide. Treatment options for MM have evolved in the last two decades with the introduction of novel therapeutic agents such as immunomodulatory drugs (IMiDs), proteasome inhibitors (PI), anti-CD-38 monoclonal antibodies (anti-CD38 MoAb), and recently BCMA-directed therapies (BDT). The variable access globally, especially for novel agents, has been a concern. We aim to study the global availability of 14 chemoimmunotherapy options in addition to autologous stem cell transplant (ASCT) which is approved in the US (excluding BDT due to limited availability), to identify regions with restricted access and analyze the main barriers to access. Methods A global cohort of oncologists outside the USA who treat MM participated in an online survey to evaluate the patterns of accessibility of MM therapies worldwide. The survey, conducted in collaboration with the US Myeloma Innovations Research Collaborative (USMIRC), was sent electronically to 176 oncologists worldwide (outside the US) from June 18th, 2023, to July 17th, 2023. It included questions on demographics, access, and perceived barriers. The respondents chose a response for each therapy as being “easily accessible”, “moderately accessible,” “not readily accessible” or “no access”. Countries were then classified as having “adequate access” if 80-100% of respondents affirmed easy/moderately easy access, while <30% were considered “limited access”, 60-79% were “high-intermediate access” and 30-59% were “low-intermediate access”. We classified countries into low- and high-income (LIC and HIC) based on the United Nations (UN) World Economic Classifications based on per capita gross national income (GNI). Means were calculated for regions of interest. An interim analysis is reported. Results Demographics: Ninety-Five (54%) oncologists from 33 countries completed the survey. Most were from Asia (56%). Others were Europe (19%), South America (12%), Africa (7%), Oceania (3%), and North America (Canada and Mexico, excluding the US) (3%). Only 17% specialized in plasma cell disorders; 50.5% were affiliated with university academic centers; 18% with private or community practices; 12% with community academic centers; and 17% were hybrid. Public-funded centers represented 61.1%, while 76% were transplant centers. Global Patterns: Most countries had adequate access to chemotherapies, IMiDs, PIs, Anti-CD38, MoAbs, and ASCT (Figure 1). Notably, ixazomib, isatuximab, and selinexor had low intermediate access, while elotuzumab had limited access. Access by Income: Most MM therapies were available in LIC and HIC. Of the therapies listed, 6 were adequately available in LIC and HIC: cyclophosphamide, lenalidomide, pomalidomide, daratumumab, bortezomib, and ASCT (Table 1). Elotuzumab and selinexor were limited in both LIC and HIC. Ixazomib and isatuximab were also limited in LIC but were low-intermediate in HIC. Access by Continent: Out of the 14 therapies, Europe had adequate or high-intermediate access to most modalities (12), followed by Oceania and Asia (10), and South America (9). North America and Africa had the lowest number of adequate or high intermediate access therapies (7) (Table 1). Barriers: The most common reason cited for limited access to MM therapies globally was the financial burden for the healthcare system, followed by limitations in local agency approval, inadequate chemotherapy suite resources, and inadequate staffing. Conclusion While most therapies were available, novel therapies such as isatuximab, ixazomib, selinexor, and elotuzumab were less readily accessible. Moreover, North America and Africa had the least access to therapies. This is likely because LIC and HIC have prioritized access to treatments with the best evidence of cost-effectiveness, while those with lower cost-effectiveness are generally limited. The financial burden on healthcare is a major limiting factor. USMIRC plans to investigate potential solutions and pursue global collaborative efforts to reduce disparities in therapies.

ImportanceCytokine storm due to COVID-19 can cause high morbidity and mortality and may be more common in patients with cancer treated with immunotherapy (IO) due to immune system activation.ObjectiveTo determine the association of baseline immunosuppression and/or IO-based therapies with COVID-19 severity and cytokine storm in patients with cancer.Design, Setting, and ParticipantsThis registry-based retrospective cohort study included 12 046 patients reported to the COVID-19 and Cancer Consortium (CCC19) registry from March 2020 to May 2022. The CCC19 registry is a centralized international multi-institutional registry of patients with COVID-19 with a current or past diagnosis of cancer. Records analyzed included patients with active or previous cancer who had a laboratory-confirmed infection with SARS-CoV-2 by polymerase chain reaction and/or serologic findings.ExposuresImmunosuppression due to therapy; systemic anticancer therapy (IO or non-IO).Main Outcomes and MeasuresThe primary outcome was a 5-level ordinal scale of COVID-19 severity: no complications; hospitalized without requiring oxygen; hospitalized and required oxygen; intensive care unit admission and/or mechanical ventilation; death. The secondary outcome was the occurrence of cytokine storm.ResultsThe median age of the entire cohort was 65 years (interquartile range [IQR], 54-74) years and 6359 patients were female (52.8%) and 6598 (54.8%) were non-Hispanic White. A total of 599 (5.0%) patients received IO, whereas 4327 (35.9%) received non-IO systemic anticancer therapies, and 7120 (59.1%) did not receive any antineoplastic regimen within 3 months prior to COVID-19 diagnosis. Although no difference in COVID-19 severity and cytokine storm was found in the IO group compared with the untreated group in the total cohort (adjusted odds ratio [aOR], 0.80; 95% CI, 0.56-1.13, and aOR, 0.89; 95% CI, 0.41-1.93, respectively), patients with baseline immunosuppression treated with IO (vs untreated) had worse COVID-19 severity and cytokine storm (aOR, 3.33; 95% CI, 1.38-8.01, and aOR, 4.41; 95% CI, 1.71-11.38, respectively). Patients with immunosuppression receiving non-IO therapies (vs untreated) also had worse COVID-19 severity (aOR, 1.79; 95% CI, 1.36-2.35) and cytokine storm (aOR, 2.32; 95% CI, 1.42-3.79).Conclusions and RelevanceThis cohort study found that in patients with cancer and COVID-19, administration of systemic anticancer therapies, especially IO, in the context of baseline immunosuppression was associated with severe clinical outcomes and the development of cytokine storm.Trial RegistrationClinicalTrials.gov Identifier: NCT04354701

Haploidentical stem cell transplantation provides a plausible alternative for the patients when a fully matched donor is unavailable. Historically, the decision of considering haploidentical transplant has remained elusive; however, with the recent advances, the consideration of haploidentical grafts as a treatment option has become more apparent for both allografting for diseases and engraftment failure. We are reporting here an anecdotal case of a successful haploidentical engraftment in a patient with the prior graft failure of an HLA-matched related donor. Since the patient was severely alloimmunized, desensitization protocol was utilized before the haploidentical transplant, and the patient after 8 months of her second allogeneic transplantation is doing great with successful engraftment, no relapse, and no graft-versus-host disease (GVHD). Numerous reports pertinent to haploidentical graft have shown favorable outcomes in the graft placement, a decline in the rate of GVHD, and an improvement in the morbidity and mortality in affected individuals. Based on the current reports, haploidentical transplantation might be more feasible and has meaningful implications in the situations where matched donors are infrequent.
