I. Aetna considers non-myeloablative hematopoietic cell transplantation
(mini-allograft) medically necessary for members with any of the following
diseases for which conventional allogeneic hematopoietic cell
transplantation is considered an established alternative. Persons who are
unable to tolerate a conventional allogeneic hematopoietic cell transplant
may be able to tolerate a milder, non-myeloablative conditioning regimen.
In these cases, mini-allografting represents a technical modification of an
established procedure.

Background
Conventional allogeneic stem cell transplant is an effective therapeutic option for
some malignancies and hematological disorders such as acute lymphoblastic
leukemia (ALL), acute myelogenous leukemia (AML), aplastic anemia (AA), chronic
myelogenous leukemia (CML), Hodgkin's disease (HD), multiple myeloma (MM),
non-Hodgkin's lymphoma (NHL), myelodysplasia, neuroblastoma, sickle cell

anemia, and thalassemia major. However, high-dose conditioning regimens
designed both to control the malignancy and to prevent graft rejection are
associated with a high incidence of transplant-related organ toxicity and mortality.
This results in the preclusion of the use of allografting for patients older than 55
years or for younger patients with certain pre-existing organ damage. Thus, studies
have been ongoing to develop safer allografting procedures that can be extended
to older patients or patients with pre-existing organ dysfunction who are currently
excluded from consideration for allografting. New strategies for allografting entail
the use of less intensive conditioning therapy that is administered with the sole
purpose of facilitating allogeneic engraftment. Pre-clinical studies in a canine
model have demonstrated that conditioning regimens for allografting can be
markedly reduced in intensity yet still attain the goal of engraftment. This reduced
intensity conditioning transplant, also known as non-myeloablative transplant or mini-
allograft, is usually based on low dose total body irradiation or fludarabine alone or
in combination with other drugs followed by a short course of immunosuppression
with post-grafting cyclosporine and methotrexate or mycophenolate mofetil. Mini-
allograft, however, may be associated with severe side effects since non-
myeloablative regimens used in this procedure rely on immunosuppressive treatment
to prevent graft-versus-host disease (GVHD) following transplantation. Such
treatment predisposes patients to infections and may also lower the anti-malignancy
effects of donor cells.
For patients with ALL, AML, AA, CML, HD, MM, NHL, myelodysplasia,
neuroblastoma, sickle cell anemia, or thalassemia major who are eligible for
conventional ASCT, mini-allograft is a technical variation of an established
procedure. On the other hand, for patients with ALL, AML, AA, CML, HD, MM, NHL,
myelodysplasia, neuroblastoma, sickle cell anemia, or thalassemia major as well as
patients with other malignancies, who are ineligible for conventional ASCT, mini-
allograft is still considered an investigational procedure.
Nagler et al (2000) reported that fludarabine-based conditioning with reduced
amounts of chemotoxic drugs before allogeneic transplant appeared to be
beneficial for patients with high-risk malignant lymphoma (n = 23). Engraftment
was fast. There was no rejection or non-engraftment. Organ toxicity was moderate
with no hepatic or renal toxicity higher than grade II. Four patients developed
higher than grade II GVHD. Seven patients died -- 4 of grade III-IV GVHD and
severe infections, 2 of bacterial sepsis, 1 of respiratory failure. Ten patients were
alive after 22.5 (range of 15 to 37) months. Survival and disease-free survival at 37

months were both 40 %. Probability of relapse was 26 %. The authors concluded
that these encouraging findings suggested that allogeneic transplant following
fludarabine-based low intensity conditioning in high-risk malignant lymphoma
patients warranted further investigation.
In a prospective multi-center study (n = 71), Martino and associates (2001)
concluded that reduced intensity conditioning regimens resulted in low early toxicity
following allografting, with stable donor hematopoietic engraftment, with an
apparent low-risk of acute GVHD. However, chronic GVHD developed in a
significant number of patients. These findings suggested that reduced intensity
conditioning allogeneic peripheral blood stem cell transplantation might lower the
risk of dying from an opportunistic infection and reduce the occurrence of
cytomegalovirus infection and disease. Overall, the development of GVHD (acute
or chronic) was an important risk factor for these complications. Other infections
continued to pose a significant threat to recipients of reduced intensity conditioning
allografts. Kroger and co-workers (2001) reported that fludarabine dose-reduced
conditioning prior to allogeneic stem cell transplantation in high-risk myelodysplastic
syndrome patients (n = 12), who were ineligible for standard transplantation,
resulted in stable engraftment with complete chimerism, but the toxicity and relapse
rate were considerable.
In a recent review, Schanz (2001) stated that although mini-allograft is feasible,
less toxic than conventional stem cell grafting, severe side effects have been
reported and are not uncommon. Realistic outcome estimations cannot be made
yet due to the still short follow-up periods. Nevertheless, mini-allograft is a
treatment option and its position in the management of hematological and
oncological diseases will become clearer in the future. This observation was
echoed by Feinstein and Storb (2001) who stated that preliminary results of mini-
allograft were encouraging. If long-term effectiveness of this approach were
demonstrated, such strategies would expand therapeutic options for patients who
would otherwise be excluded from receiving conventional allografts.
In a review of the chemotherapy effects in patients with AML, Kimby et al (2001)
stated that allogeneic stem cell transplantation following mini-allograft induced a host-
versus-graft tolerance and an immune graft-versus-leukemia effect. This new
approach of immunotherapy appears to result in a low procedure-related mortality,
however, long-term effects are unknown and evaluation in controlled clinical studies
is needed. van Besien and colleagues (2001) noted that mini-allograft has been

examined as a means to lower treatment-related mortality in patients with CLL,
however extended follow-up is needed to establish the cure rate obtained with this
procedure.
Some of the conclusions from the 1999 European Group for Blood and Marrow
Transplantation (EBMT) Workshop on allogeneic hematopoietic stem cell
transplantation (HSCT) following non-myeloablative conditioning, also known as
reduced intensity (RI) conditioning regimen were as follows (Bacigalupo, 2000):
RI-HSCT may be appropriate in chronic disorders such as chronic
lymphoproliferative diseases. Chronic myeloid leukemia should be studied.
It remains to be determined whether RI-HSCT is beneficial in patients with solid
tumors.
Some of the findings/conclusions from the 2nd EMBT Workshop on allogeneic
transplantation following non-myeloablative conditioning held in 2001 were as
follows (Bacigalupo, 2002):
It is probably too early to give a clear message on the role of allogeneic RI-
HSCT in patients with solid tumors. Some responses have been recorded in
breast cancer and renal cell carcinoma, but results in melanoma appear to be
less encouraging.
There are very little data on the use of RI-HSCT for patients with myeloma.
A high relapse rate (60 % at 2 years) suggested that RI-HSCT in advanced
and/or high-grade lymphomas is unlikely to be successful.
There are little data on the use of RI-HSCT for patients with high-risk leukemia
or myelodysplasia (e.g., patients with acute leukemia in relapse or patients with
transformed myelodysplasia).
There was no specific program described for patients with ALL.
Reducing intensity programs are being optimized and tested in selected
indications including unrelated donor transplants.
The comparison with conventional programs will probably be tested.
In an updated technology assessment on "Non-myeloablative bone marrow and
peripheral stem cell transplantation" by the Wessex Institute for Health Research
and Development, Muthu (2001) stated that the updated search has not altered the
conclusions of the review. The patient populations of the reviewed studies

consisted mainly of individuals who are considered unsuitable for conventional
allograft. The research regarding safety and effectiveness of mini-transplant is still
in an early phase. Studies are heterogeneous in terms of their populations and
interventions, and are uncontrolled. Results are promising, especially if it may be
assumed that prognosis is consistently worse with alternative treatment strategies
in the studied patient groups. However, the conclusion remains tentative pending
larger, preferably controlled-studies with consistent and explicit inclusion and
exclusion criteria, consistent co-interventions and longer follow-up.
Shaughnessy and colleagues (2006) carried out a phase I and pharmacokinetic
study of once-daily, intravenously administered busulfan in the setting of a reduced-
intensity preparative regimen and matched sibling donor allogeneic stem cell
transplantation for treatment of metastatic renal cell carcinoma. Seven male
patients with metastatic renal cell carcinoma received intravenously administered
busulfan at 3.2 mg/kg once daily on day -10 and day -9, fludarabine at 30 mg/m2
on day -7 through day -2, and equine anti-thymocyte globulin at 15 mg/kg per day
on day -5 through day -2. The mean area under the plasma concentration-time
curve (AUC) and the half-life of the first dose of intravenously administered
busulfan were 6,253 microM x minute (range of 5,036 to 7,482 microM x minute)
and 3.37 hours (range of 2.54 to 4.00 hours), respectively. The AUC was higher
than predicted from extrapolation of AUC data for the same total dose of
intravenously administered busulfan divided into four doses daily. Patients
experienced greater than expected regimen-related toxicity for a reduced-intensity
preparative regimen, and the study was stopped. The authors concluded that this
preparative regimen was associated with unacceptable regimen-related toxicity
among patients with metastatic renal cell carcinoma.
Norton and Roberts (2006) noted that Evans syndrome is an uncommon condition
defined by the combination (either simultaneously or sequentially) of immune
thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA) with a positive
direct antiglobulin test (DAT) in the absence of known underlying etiology. This
chronic disorder is characterized by frequent exacerbations and remissions. First-
line therapy usually entails corticosteroids and/or intravenous immunoglobulin, to
which most patients respond; however, relapse is frequent. Second-line treatments
include immunosuppressive drugs, especially ciclosporin or mycophenolate mofetil;
vincristine; danazol or a combination of these agents. More recently a small
number of patients have been treated with rituximab, which induces remission in
the majority although such responses are often sustained for less than 12 months

and the long-term effects in children are unclear. Splenectomy may also be
considered although long-term remissions are less frequent than in uncomplicated
ITP. For very severe and refractory cases stem cell transplantation (SCT) offers
the only chance of long-term cure. The limited data available suggested that ASCT
may be superior to autologous SCT but both carry risks of severe morbidity and of
transplant-related mortality. Cure following RI conditioning has now been reported
and should be considered for younger patients in the context of controlled clinical
trials.
In a phase I/II clinical trial, Burt and colleagues (2009) evaluated the safety and
clinical outcome of autologous non-myeloablative hemopoietic SCT in patients with
relapsing-remitting multiple sclerosis (MS) who had not responded to treatment with
interferon beta. Eligible patients had relapsing-remitting MS, and despite treatment
with interferon beta had had two corticosteroid-treated relapses within the previous
12 months, or one relapse and gadolinium-enhancing lesions seen on MRI and
separate from the relapse. Peripheral blood hemopoietic stem cells were mobilized
with 2 g/m2 cyclophosphamide and 10 microg/kg/day filgrastim. The conditioning
regimen for the hemopoietic stem cells was 200 mg/kg cyclophosphamide and
either 20 mg alemtuzumab or 6 mg/kg rabbit anti-thymocyte globulin. Primary
outcomes were progression-free survival and reversal of neurological disability at 3
years post-transplantation. These researchers also examined the safety and
tolerability of autologous non-myeloablative hemopoietic SCT. A total of 21
patients were treated. Engraftment of white blood cells and platelets was on
median day 9 (range of day 8 to 11) and patients were discharged from hospital on
mean day 11 (range of day 8 to 13). One patient had diarrhea due to clostridium
difficile and 2 patients had dermatomal zoster; 2 of the 17 patients receiving
alemtuzumab developed late immune thrombocytopenic purpura that remitted with
standard therapy. Overall, 17 of 21 patients (81 %) improved by at least 1 point on
the Kurtzke expanded disability status scale (EDSS), and 5 patients (24 %)
relapsed but achieved remission after further immunosuppression. After a mean of
37 months (range of 24 to 48 months), all patients were progression-free (no
deterioration in EDSS score), and 16 were relapse-free. Significant improvements
were noted in neurological disability, as determined by EDSS score (p < 0.0001),
neurological rating scale score (p = 0.0001), paced auditory serial addition test (p =
0.014), 25-foot walk (p < 0.0001), and quality of life, as measured with the short form-
36 questionnaire (p < 0.0001). The authors concluded that non-myeloablative
autologous hemopoietic SCT in patients with relapsing-remitting MS reverses
neurological deficits, but these results need to be confirmed in a randomized trial.

Burdach and colleagues (2000) compared outcome after autologous and allogeneic
stem-cell transplantation (SCT) in patients with advanced Ewing's tumors. These
investigators analyzed the results of 36 patients who were treated with the
myeloablative Hyper-ME protocol (hyper-fractionated total body irradiation,
melphalan, etoposide +/- carboplatin). Minimal follow-up for all patients was 5
years. All subjects underwent remission induction chemotherapy and local
treatment before myeloablative therapy. Seventeen of 36 patients had multi-focal
primary Ewing's tumor, 18 of 36 had early, multiple or multi-focal relapse, 1 of 36
patients had unifocal late relapse. Twenty-six of 36 were treated with autologous
and 10 of 36 with allogeneic hematopoietic stem cells. These researchers
analyzed the following risk factors, which could possibly influence the event-free
survival (EFS): number of involved bones, degree of remission at time of SCT, type
of graft, indication for SCT, bone marrow infiltration, bone with concomitant lung
disease, age at time of diagnosis, pelvic involvement, involved compartment
radiation, histopathological diagnosis. Event-free survival for the 36 patients was
0.24 (0.21) +/- 0.07. Eighteen of 36 patients suffered relapse or died of disease, 9
of 36 died of treatment related toxicity (DOC). Nine of 36 patients are alive in
complete remission (CR). Age greater than or equal to 17 years at initial diagnosis
significantly deteriorated outcome (p < 0.005). According to the type of graft, EFS
was 0.25 +/- 0.08 after autologous and 0.20 +/- 0.13 after allogeneic SCT.
Incidence of DOC was more than twice as high after allogeneic (40 %) compared to
autologous (19 %) SCT, even though the difference did not reach significance (p =
0.08, Fisher's exact test). The authors concluded that because of the rather short
observation period, secondary malignant neoplasms may complicate the future
clinical course of some of the patients who were viewed as event-free survivors.
Event-free survival in patients with advanced Ewing's tumors is not improved by
allogeneic SCT due to a higher complication rate. Furthermore, Capitini and
colleagues (2009) noted that further clinical trials are needed to evaluate the role
for allogeneic SCT for Ewing's sarcoma.
Duvic et al (2010) examined the safety and effectiveness of total skin electron
beam with allogeneic HSCT in patients with cutaneous T-cell lymphoma (CTCL). A
total of 19 patients with advanced CTCL (median age of 50 years; 4 prior therapies)
underwent total skin electron beam radiation followed by allogeneic HSCT;
16 patients were conditioned with fludarabine (125 mg/m(2)) and melphalan (140
mg/m(2)) plus thymoglobulin (for mis-matched donors). Graft-versus-host disease
prophylaxis was with tacrolimus/mini methotrexate. Eighteen patients experienced
engraftment, and 1 died as a result of sepsis on day 16. Median time to recovery of

absolute neutrophil count (ANC) was 12 days. Fifteen achieved full donor
chimerism, 12 had acute GVHD, and 12 were treated for chronic GVHD. The
overall intent-to-treat response was 68 %, and the complete response rate was 58
%. Four of 6 patients died in complete remission as a result of bacterial sepsis (n =
2), chronic GVHD and fungal infection (n = 1), or lung cancer (n = 1); only 2 died as
a result of progressive disease. Eight subjects experienced relapse in skin; 5
regained complete response with reduced immunosuppression or donor
lymphocyte infusions. Eleven of 13 are currently in complete remissions, with
median follow-up of 19 months (range of 1.3 to 8.3 years). Median overall survival
has not been reached. The authors concluded that total skin electron beam
followed by allogeneic HSCT is a promising treatment for selected patients with
refractory CTCL and merits additional evaluation in high-risk patients with advanced
disease who had poor survival and matched donors.
Acquired Angioedema
Zegers and colleagues (2015) stated that acquired angioedema is a rare disorder
causing recurrent life-threatening angioedema, due to decreased activity of C1
esterase inhibitor. These researchers reported on the case of a 57-year old man
presented to the authors’ hospital with recurrent swelling of the hands, lips, tongue,
scrotum and throat. Laboratory examination showed the presence of an IgM kappa
monoclonal antibody; additional analysis showed that in the IgM fraction
autoantibody activity against C1 esterase inhibitor was present. This confirmed the
diagnosis of acquired angioedema in the presence of lympho-plasmacytic
lymphoma. Despite standard therapy, there was an increase in the episodes of
laryngeal edema. Therefore it was decided to perform a non-myeloablative
allogeneic HSCT, with his HLA-identical brother as donor. The post-transplantation
course was without complications; 5 years following allo-SCT he is in CR without
symptoms and with increased C1 esterase inhibitor activity. The authors concluded
that this was the first case describing treatment of severe acquired angioedema,
that had failed all known therapeutic options, with an allo-SCT.
Furthermore, UpToDate reviews on “Acquired C1 inhibitor deficiency: Management
and prognosis” (Cicardi, 2016) and “An overview of angioedema: Clinical features,
diagnosis, and management” (Zuraw and Bingham, 2016) do not mention the use
of non-myeloablative hematopoietic cell transplantation/mini-allograft as a
therapeutic option.

Inherited Hemophagocytic Lymphohistiocytosis
Kuriyama and associates (2016) noted that inherited hemophagocytic
lymphohistiocytosis (HLH) is a genetic anomaly disorder in which abnormally
activated cytotoxic T lymphocytes cannot induce the apoptosis of target cells and
antigen-presenting cells, leading to hemophagocytosis, pancytopenia, and a variety
of symptoms such as a high fever. These investigators presented the case of a
patient with adult-onset HLH developed refractory disease despite receiving
immunosuppressive treatments. He underwent a reduced-intensity conditioning
(RIC) regimen that comprised anti-thymocyte globulin (ATG) followed by cord blood
transplantation (RIC-CBT). He achieved and maintained a complete donor type.
The authors concluded that the incorporation of ATG into RIC-CBT may prevent
graft failure and control hemophagocytosis, however, they stated that further efforts
are needed to reduce infectious complications.
Furthermore, an UpToDate review on “Treatment and prognosis of hemophagocytic
lymphohistiocytosis” (McClain, 2016) does not mention the use of non-
myeloablative hematopoietic cell transplantation/mini-allograft as a therapeutic
option.
Mucopolysaccharidosis Types II, III and IV
Yokoi and associates (2015) stated that mucopolysaccharidosis type II (MPS II) is a
lysosomal storage disorder caused by deficient activity of the iduronate-2-sulfatase
(IDS) resulting in the accumulation of glycosaminoglycans (GAGs) in the
lysosomes of various cells. Although it has been proposed that BMT may have a
beneficial effect for patients with MPS II, the requirement for donor-cell chimerism
to reduce GAG levels is unknown. To address this issue, these investigators
transplanted various ratios of normal and MPS II bone marrow cells in a mouse
model of MPS II and analyzed GAG accumulation in various tissues. Chimerism of
whole leukocytes and each lineage of BMT recipients' peripheral blood was similar
to infusion ratios; GAGs were significantly reduced in the liver, spleen, and heart of
recipients. The level of GAG reduction in these tissues depended on the
percentage of normal-cell chimerism. In contrast to these tissues, a reduction in
GAGs was not observed in the kidney and brain, even if 100 % donor chimerism
was achieved. The authors concluded that these results suggested that a high
Proprietary
http://www.aetna.com/cpb/medical/data/600_699/0634.html 09/24/2019
Page 12 of 23
degree of chimerism is needed to attain the maximum effect of BMT, and donor
lymphocyte infusion (DLI) or enzyme replacement therapy (ERT) might be
considered options in cases of low-level chimerism in MPS II patients.
Yokoi and colleagues (2016) noted that although ERT is available as a treatment of
MPS II, there are some limitations, such as the requirement of weekly
administration for the entire life. To avoid such limitations, HSCT is a possible
alternative. In fact, some report suggested positive effects of HSCT for MPS II.
However, HSCT has also some limitations since strong conditioning regimens can
cause severe side effects. To overcome this obstacle, these researchers studied
the effectiveness of ACK2, an antibody that blocks KIT, followed by low-dose
irradiation as a pre-conditioning regimen for HSCT using a murine model of MPS II.
This protocol achieved 58.7 ± 4.92 % donor chimerism at 16 weeks after
transplantation in the peripheral blood of recipient mice; GAG levels were
significantly reduced in liver, spleen, heart and intestine. The authors concluded
that these findings showed that ACK2-based pre-conditioning might be one of the
choices for MPS II patients who receive HSCT.
Furthermore, an UpToDate review on “Mucopolysaccharidoses: Complications and
management” (Wynn, 2017) stated that “HCT has also improved the clinical
outcomes of patients with milder MPS I and II, and MPS VI and VII. However, HCT
has not prevented the central nervous system (CNS) decline in patients with severe
MPS II in most series and has not been successful in other types of MPS. MPS III
A to D patients usually do not benefit and may worsen after the procedure. HCT
does not correct the bony abnormalities in MPS IV A and IV B or MPS I. The
reason for the lack of success of HCT in some types of MPS is uncertain, although
it is possible that the transplanted cells do not secrete sufficient enzyme, or the
enzyme may not be taken up sufficiently to correct the deficiency. It is possible
outcomes in some of these populations may improve with early HCT with full donor
engraftment from a non-carrier donor. This question warrants further study”.
