Single-agent melphalan 200 mg/m2 IV is the conditioning regimen of choice
for autologous stem cell transplant in multiple myeloma.
IV melphalan has poor solubility and limited chemical stability upon reconstitution. Most formulations contain propylene glycol as co-solvent , which can occasionally cause metabolic dysfunction and arrhythmias.

This study evaluated outcomes of 4 different conditioning regimen used for autologous SCT in MM:
- MEL200: Melphalan 200 mg/m2 (472 patients)
- MEL140+TBI: - Melphalan 140 mg/m2 + Total Body Irradiation (135 patients)
- BU-MEL: Busulfan 12 mg/Kg + Melphalan 140 mg/m2 (186 patients)
- BU-CY: Busulphan 14 mg/Kg + Cyclophosphamide 120 mg/Kg (28 patients)
There were no significant differences between the 4 conditioning regimens, in terms of hematological recovery and transplant-related mortality. Response rate was 100% with BU-MEL and 86-93% in the other groups (p<0.05). Differences in event-free survival and overall survival did not reach statistical significance.

This is a prospective and randomized trial that compared 2 conditioning regimens:
- Melphalan 140 mg/m2 + TBI 8 Gy (140 patients)
- Melphalan 200 mg/m2 (142 patients)
Mel 200 was the winner, because it was less toxic and at least as effective as Mel 140 + TBI.
- The duration of neutropenia and thrombocytopenia was shorter
- The transfusion requirements lower
- The median duration of hospitalization was shorter
- The incidence of severe mucositis was decreased
- EFS was similar (20.5 vs 21 months)
- Overall survival at 45 months was improved (65.8% vs 45.5%, p=0.05)

In this study, 90 patients with newly diagnosed myeloma were treated with two autologous transplants using melphalan 100 mg/m2, and their outcomes were compared with those of a control group of 90 patients treated with melphalan 200 mg/m2. Results favored the higher dose:
- Rate of complete remission was 35% with MEL100 and 48% with MEL200 (p=0.08)
- Median event-free survival was 32 months with MEL100 and 42 months with MEL200 group (p<0.005)
- Median overall survival was similar
- Toxicity was inferior with MEL100, but transplant-related mortality was similar

This is a randomized study of 298 myeloma patients treated with tandem autologous SCT and assigned to either melphalan 200 mg/m2 or melphalan 100 mg/m2. Results:
- Treatment-related mortality: about 3% in both groups
- RR was 79% with MEL200 and 72% with MEL100
- CR was 15% with MEL200 and 8% with MEL100
- Median PFS: 31 months with MEL200 and 26 months with MEL100
- Median OS: not significantly different
The authors conclude that MEL200 should be considered the standard conditioning regimen, because it leads to longer remission duration.

In this retrospective study, 1719 patients with multiple myeloma received melphalan 200 mg/m2 as conditioning regimen for an autologous stem cell transplant, whereas 245 received 140 mg/m2, due to anticipated high risk of toxicities. Overall survival and progression-free survival were similar in the 2 groups. Multivariable subgroup analysis showed that melphalan 200 mg/m2 was better in patients transplanted in less than partial response, whereas the opposite was true in patients with VGPR or complete response.

In this study, 131 patients with multiple myeloma underwent an autologous stem cell transplant using high-dose melphalan. They were randomized to receive either the standard dose 200 mg/m2 (Mel200), or a higher dose 280 mg/m2 (Mel280). Melphalan was given IV over 30 minutes on day -2. All patients received cryotherapy and amifostine. Results:
- nCR + CR: 22% with Mel200 and 39% with Mel280 (p=0.03)
- Progression-free survival at 1 year: 83% with Mel200 and 78%
- Progression-free survival at 3 years: 46% with Mel200 and 54% with Mel280
- Grade 3 mucositis: 0 with Mel200 and 1 with Mel280
- No patient died in the entire study group
In conclusion, Mel280 was safe and induced a higher rate of deep responses. The size of the trial was judged to be too small to demonstrate a survival advantage for Mel280.
BEAM Conditioning Regimen Has Higher Toxicity Compared With High-Dose

In this study, 43 patients with myeloma received a second autologous stem cell transplant at relapse after the first one. The conditioning regimen was high-dose melphalan with the first transplant, whereas it was either melphalan (19 patients) or BEAM (BCNU, etoposide, cytarabine, and melphalan) with the second one. The results favored melphalan:
- The median progression free-survival was similar: 12.1 months with melphalan, and 7.7 months with BEAM (p=0.82)
- BEAM was associated with higher toxicity, especially fever and infections (whereas melphalan was associated with a higher incidence of mucositis)

This is a phase II trial of 74 patients with relapsed/refractory myeloma, treated with an autologous stem cell transplant. They used a conditioning regimen with gemcitabine, busulfan, and melphalan instead of the standard single agent melphalan. Results were compared to those of 184 patients who received melphalan alone. Despite similar post-transplant maintenance, the progression-free survival was better with the three drugs instead of one (15 vs 9 months). There were 3 deaths (4%), 2 due to sepsis and 1 due to a cardiac event.

The standard conditioning regimen for autologous stem cell transplants in patients with multiple myeloma has been single agent high-dose melphalan, usually 200 mg/m2. In this retrospective study, 104 patients received a combination of high-dose melphalan and carmustine (BCNU), another alkylating agent. These transplants were done between 1997 and 2002, and the results were compared to those of 103 patients who received high-dose melphalan alone, between 2001 and 2008. The outcomes were better in the group treated with melphalan-carmustine: the median progression-free survival was 40.4 vs 20.5 months (p<0.001), and the median overall survival was 88.4 vs 67.2 months (but the difference was not statistically significant: p=0.07). Transplant-related mortality was similar: 2.9% vs 3.9%).

Fenk R, Schneider P, Kropff M, Huenerlituerkoglu AN, Steidl U, Aul C, Hildebrandt B, Haas R, Heyll A, Kobbe G; West German Myeloma Study Group.
This is a randomized trial comparing two conditioning regimens for autologous transplants in 56 patients with myeloma:
- The standard regimen was melphalan 200 mg/m2
- The intensified regimen consisted of melphalan 200 mg/m2 + cyclophosphamide 120 mg/kg + idarubicin 42 mg/m2
The study was discontinued early, because the intensified regimen was associated with unacceptable toxicity: treatment-related mortality was 20% (vs 0% with the standard regimen, mainly because of infections.

In this study, 54 patients with newly diagnosed MM underwent autologous stem cell transplantation with melphalan 200 mg/m2 (standard regimen) + bortezomib 1 mg/m2 x 4, on days -6, -3, +1, +4. Bortezomib did not delay hematologic recovery. At least VGPR was observed in 70% of patients, and CR rate was 32%. When comparing results with a matched group treated with only melphalan, CR was higher (35% vs 11%; p= 0.001).

Kazmi SM, Saliba RM, Donato M, Wang M, Hosing C, Qureshi S, Anderlini P, Popat U, Champlin RE, Giralt SA, Qazilbash MH.
Median progression-free survival in 60 patients treated with autologous SCT, using topotecan, cyclophosphamide, and melphalan as conditioning regimen, was 18.5 months, similar to the PFS seen with high-dose melphalan.
After melphalan 200 mg/m2 on day -1, hematopoietic recovery occurs within 2 weeks in >90% of patients: ANC >500 at about day +11, and platelets >20,000 unsupported at about day +13.
The use of G-CSF, to accelerate neutrophil engraftment, is not always necessary. It may anticipate resolution of neutropenia by 1-2 days, but it is associated with several side effects (e.g., fatigue, bone pain, fever, engraftment syndrome, fluid retention, and allergic reactions).

37 consecutive patients with myeloma treated with high-dose melphalan and autologous peripheral blood stem cell transplantation were randomly assigned to receive:
- Filgrastim 5 mcg/kg SC qd starting on day +5 (19 patients)
- Peg-filgrastim 6 mg SC x1 on day +1 (n = 18 patients)
The median duration of neutropenia in the Filgrastim and Pegfilgrastim groups was similar, but the incidence of febrile neutropenia (100% vs 61%) and the duration of febrile neutropenia (4 days vs 1.5 days) were lower in the Pegfilgrastim arm.
Ideal body weight correlates better with engraftment after PBSC autograft

Shah N, Shi Q, Williams LA, Mendoza TR, Wang XS, Reuben JM, Dougherty PM, Bashir Q, Qazilbash MH, Champlin RE, Cleeland CS, Giralt SA.
In this study, 80 patients 60 year-old and older with either myeloma or amyloidosis were treated with an autologous transplant using melphalan 200 mg/m2. They were randomized to receive either a standard dose of stem cells (median, 5.1 million CD34+ cells/Kg) or a higher dose (median, 10.5 million CD34+ cells/Kg). The results were negative: patients receiving the high dose of stem cell did not experience a more rapid engraftment of neutrophils and platelets, and they did not experience an improvement of their transplant-related symptoms.
Fractionated stem cell infusions for patients with plasma cell myeloma
undergoing autologous hematopoietic cell transplantation.

Landau H, Wood K, Chung DJ, Koehne G, Lendvai N, Hassoun H, Lesokhin A, Hoover E, Zheng J, Devlin SM, Giralt S.
In this study, 22 patients with myeloma underwent an autologous stem cell transplant with fractionated stem cell infusions, i.e., with multiple cell infusions at days 0,, +2, +4, and +6. The results were compared to those of 77 patients who received the stem cells in the traditional way, i.e., with all cells on day 0. The results of the study were negative, because the fractionation did not shorten the number of days of neutropenia, the days of fever, infections, antibiotic use, diarrhea, and length of hospital admission.
There are many possible toxicities after high-dose
chemotherapy. They include:
- Neutropenia, with possibility of infections and sepsis
- Anemia requiring blood transfusions
- Thrombocytopenia, with possibility of hemorrhages
- Nausea and vomiting
- Oral mucositis, which may require opioid analgesia and total parenteral nutrition
- Intestinal mucositis, with diarrhea
- Transient alopecia
The mortality of high-dose melphalan approximately 1-2%.

In this study, 362 patients with multiple myeloma undergoing autologous stem cell transplant with high-dose melphalan were randomized to either granisetron + dexametasone + placebo (181 patients), or granisetron + dexamethasone + aprepitant (181 patients). Results favored the aprepitant group:
- Absence of significant nausea within 120 hours of melphalan administration: 88% with placebo, and 94% with aprepitant
- Absence of vomiting within 120 hours of melphalan administration: 65% with placebo, and 78% with aprepitant

Oral mucositis can be mild or severe. In some cases, patients may require the use of narcotic analgesics and total parenteral nutrition (TPN).
WHO oral toxicity scale:
Grade 0 = no mucositis
Grade 1 = erythema or pain
Grade 2 = ulcers
Grade 3 = Unable to swallow solid food, but able to swallow liquid food
Grade 4 = Alimentation is not possible
Oral mucositis can be prevented with oral cryotherapy. Example: patients should hold ice chips or cold water inside their mouth for 5 min prior to the melphalan infusion, then during the infusion (20-30 min), and then for an additional 30 minutes after completion of the infusion. Patients are instructed to melt the ice inside the mouth. When ice melts, it is immediately replaced (the duration of the cryotherapy varies among protocols, from 45 minutes to more than 2 hours).
In a high-dose melphalan setting, palifermin compared
with placebo had no effect on oral mucositis or related patient's burden.

Sborov DW, Cho YK, Cottini F, Hade EM, Lamprecht M, Tackett K, Sharma N, Williams N, Li J, Devine S, Poi M, Phelps MA, Hofmeister CC.
This study analyzed outcomes of three different schedules of G-CSF given after an autologous stem cell transplant for multiple myeloma: started on day +1 (43 patients), +5 (75 patients), or +7 (103 patients). Although starting G-CSF on day -7 leads to some cost savings, the administration on day +1 was associated with better results:
- The mean time to neutrophil engraftment was 11.2 days with G-CSF on day +1, 12.3 days with G-CSF on day +5, and 12.8 days with G-CSF on day +7 (<0.001)
- The incidence of neutropenic fever was 65.1% with G-CSF on day +1, 65.3% with G-CSF on day +5, and 88.4% with G-CSF on day +7 (p=0.002)
- The incidence of significant mucositis (grade 2 or higher) was 4.7% with G-CSF on day +1, 5.3% with G-CSF on day +5, and 17.5% with G-CSF on day +7 (p=0.01)

In this study, reactivation of the varicella zoster virus (VZV) developed in 57 (30%) of 191 patients with myeloma. The VZV reactivation occurred during the induction chemotherapy (8.5% of patients), or after the autologous stem cell transplant (ASCT) (21.5% of patients). Interestingly, for unclear reasons, there was an association between the VZV reactivation after the ASCT and a better median overall survival ("not reached" vs 87 months). Patients received acyclovir 400 mg twice a day for 3 weeks after the ASCT. The incidence of VZV reactivation after the ASCT was about 10% at 1 year, about 15% at 2 years, and about 20% at 4 years.
Incidence of infection according to intravenous immunoglobulin use in
autologous hematopoietic stem cell transplant recipients with multiple myeloma.

This is a retrospective study of 162 patients with myeloma who underwent an autologous stem cell transplant. The prophylactic use of IVIG did not seem to reduce the incidence of infections (35% without IVIG, and 31% with IVIG, p=0.63), and the incidence of infections requiring hospitalization.

This is a retrospective analysis of 324 autologous stem cell transplants in 285 myeloma patients treated between 2006 and 2015. The authors observed 68 episodes of infections (21%). The most common type of infection was bacteremia (24 cases), followed by other bacterial infections (7), CMV (17), HSV (12), VZV (3), Aspergillus (3) and Pneumocystis jiroveci (2). Mortality was 1.2%, and all deaths were infection-related.
Engraftment syndrome is a frequent complication of autologous stem cell transplant. It manifests with noninfectious fever, skin rash, diarrhea, and noncardiogenic pulmonary edema. The vast majority of cases occur during or after neutrophil engraftment (between 3 days before and 7 days after ANC is 0.5). Most cases resolve spontaneously. Treatment with corticosteroids (e.g., methylprednisolone 1-1.5 mg/Kg/day) is usually effective in improving the symptoms.
Myelodysplastic syndrome after autologous peripheral
blood stem cell transplantation for multiple myeloma.

Przepiorka D, Buadi F, McClune B, Franz G, Walsh W, White F.
Among 82 myeloma patients who underwent autologous stem cell transplantation, the rate of myelodysplastic syndrome was 12% (10 patients). High-dose melphalan was the conditioning regimen received by 83% of patients. Of note, most patients received other forms of chemotherapy, and 34% received radiation therapy as well. Median overall survival after the diagnosis of myelodysplastic syndrome was 18 months.

This study reviews incidence of second cancers among 4161 patients with multiple myeloma treated with an autologous stem cell transplant. Follow-up identified 163 cases of new cancers, with a cumulative incidence of 6.1% at 7 years after transplant. The incidence of new cancers in these patients was similar to that in matched U.S. population, with the exception of AML and melanoma, which were more frequent. Multivariate analysis showed that factors associated to an increased risk of second cancers were obesity, older age, and male gender.
IMMUNE RECOVERY AFTER TRANSPLANT
Antigen-specific T-cell immunity in multiple
myeloma patients is restored following high-dose therapy: implications for
timing of vaccination.
Scand J Immunol. 2007 Oct;66(4):465-75.
Svane IM, Nikolajsen K, Johnsen HE.
This study evaluates the recovery of natural and vaccine induced immunity after autologous stem cell transplantation in patients with multiple myeloma. The authors serially measured the T-cell responses to CMV, VZV, and tetanus toxoid, and found that most patients regained specific T-cell immunity to those infections as early as 3 months after transplantation. After transplant, the CD4/CD8 ratio decreases, but antigen specific CD4+ T-cells recover prior to CD8+ T-cells.
