This is a Phase II, open-label clinical trial examining the role of Panhematin® in patients with MDS. The objective of this study is to evaluate the safety and efficacy of Panhematin® (hematin for injection) in the treatment of adult patients (≥ 18 years of age) with low-risk MDS.
The study will be conducted on an outpatient basis and will consist of the following:
- A Screening Period (within 28 days of the Day 1)
- An 8-week Treatment Period (Days 1 through 4 of Week 1, and weekly visits during Weeks 2 through 8); partial and complete responders in any of the three cell lines may continue treatment for an additional 4 weeks
- A 6-month Post treatment Follow-up Period (monthly clinic visits during Weeks 12 40)
The myelodysplastic syndromes (MDS), a diverse group of hematopoietic stem cell (HSC) disorders, are characterized by ineffective hematopoiesis that manifest clinically as anemia, neutropenia, and/or thrombocytopenia. MDS is most frequently observed in the elderly population (median age between 60 and 70 years) and has a male predominance. The incidence of MDS varies from 2.1 to 12.6 cases per 100,000 people per year, with an estimated prevalence of up to 55,000 patients in the United States [Catenacci, 2005; Williamson, 1994; Aul, 1998; Aul, 2001]. Patients with MDS most frequently present with symptoms of fatigue, pallor, exertional dyspnea, infection, bleeding or bruising [Catenacci, 2005].
MDS can be divided into 2 major subtypes: indolent (or early) MDS, in which pro-apoptotic forces predominate, and aggressive (or advanced) MDS, in which pro-proliferative factors are more common.
The only curative therapy for MDS is allogeneic transplantation [Catenacci, 2005; Thompson, 2005]. Curative treatments are restricted to younger, healthier individuals with histocompatible-matched donors or those able to undergo intensive chemotherapeutic regimens [Catenacci, 2005]. Recently, the FDA approved 3 agents for the treatment of this disease, Vidaza, Dacogen, and revlimid. The latter is approved for a subset of patients with MDS with del 5q abnormality, the former two are more applicable to higher risk disease. Rhu-EPO is currently available to patients with low risk MDS however, if they fail, their options are limited to the agents mentioned above, all of which have significant myelotoxic effects. Effective and less myelosuppressive treatments for low-risk MDS are needed.
We are proposing a novel approach for the treatment of patients with low-risk MDS using heme supplementation with Panhematin® (hemin for injection). Panhematin® is an iron-containing metalloporphyrin, indicated for the amelioration of recurrent attacks of acute intermittent porphyria; it acts to limit the hepatic and/or marrow synthesis of porphyrin, presumably, as a result of the inhibition of aminolevulinic acid synthetase (the enzyme which limits the rate of porphyrin/heme biosynthetic pathway) [Panhematin® Product Prescribing Information].
There are pre-clinical and clinical data to suggest that heme supplementation with Panhematin® (hematin for injection) has potential as a treatment option for patients with MDS. Preliminary data indicate hemin administration has the potential to stimulate progenitor cell growth, stimulate globin synthesis, and elevate overall hemoglobin levels. Panhematin® has been proven to be well tolerated when used therapeutically in patients with acute intermittent porphyria, and it is anticipated to be well tolerated in this patient population. For this study, selected patients will have low or intermediate 1 risk disease by IPSS, and the standard of care for MDS (supportive therapies) will be administered as needed. Measurement of serum porphyrin levels and Hgb F will be done at baseline and at week 8.

Clonal myeloid disorders that possess both dysplastic and proliferative features but are not properly classified as either MYELODYSPLASTIC SYNDROMES or MYELOPROLIFERATIVE DISORDERS.
Condition with a variable constellation of phenotypes due to deletion polymorphisms at chromosome location 22q11. It encompasses several syndromes with overlapping abnormalities including the DIGEORGE SYNDROME, VELOCARDIOFACIAL SYNDROME, and CONOTRUNCAL AMOMALY FACE SYNDROME. In addition, variable developmental problems and schizoid features are also associated with this syndrome. (From BMC Med Genet. 2009 Feb 25;10:16) Not all deletions at 22q11 result in the 22q11deletion syndrome.
A myelodysplastic-myeloproliferative disease characterized by monocytosis, increased monocytes in the bone marrow, variable degrees of dysplasia, but an absence of immature granulocytes in the blood.
Rare congenital disorder with multiple anomalies including: characteristic dysmorphic craniofacial features, musculoskeletal abnormalities, neurocognitive delay, and high prevalence of cancer. Germline mutations in H-Ras protein can cause Costello syndrome. Costello syndrome shows early phenotypic overlap with other disorders that involve MAP KINASE SIGNALING SYSTEM (e.g., NOONAN SYNDROME and cardiofaciocutaneous syndrome).
An autosomal dominant aneurysm with multisystem abnormalities caused by increased TGF-BETA signaling due to mutations in type I or II of TGF-BETA RECEPTOR. Additional craniofacial features include CLEFT PALATE; CRANIOSYNOSTOSIS; HYPERTELORISM; or bifid uvula. Phenotypes closely resemble MARFAN SYNDROME; Marfanoid craniosynostosis syndrome (Shprintzen-Goldberg syndrome); and EHLERS-DANLOS SYNDROME.
