SAN FRANCISCO-Results of a phase II, open-label, multicenter study show that the investigational agent STI571 holds promise for many patients with Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) whose disease has proved resistant to interferon therapy.

ASCO-STI-571, an investigational drug that has high activity in benign-phase chronic myelogenous leukemia (CML), also produces significant hematologic responses in patients with advanced-stage CML or acute forms of leukemia, Moshe Talpaz, MD, said at the 36th annual meeting of the American Society of Clinical Oncology (ASCO) in New Orleans.

Drs. Girardi and Edelson provide a concise discussion of current issues surrounding the management of patients with cutaneous T-cell lymphomas. They discuss a number of current theories regarding etiology and pathogenesis and provide a
Cutaneous T-cell lymphoma (CTCL) is a malignancy of a distinctive subset of T-helper cells designated “cutaneous T cells” because of their central role in the normal functioning of the skin immune system. Guided by
ASCO-Mylotarg (gemtuzumab ozogamicin) has received FDA approval for treatment of CD33-positive acute myelogenous leukemia (AML) in patients age 60 and older in first relapse who are poor candidates for cytotoxic therapy. The agent, manufactured by Wyeth-Ayerst, was approved as an orphan drug.

PORTLAND, Oregon-A rationally designed drug now known as STI 571 is both effective and well tolerated in treating certain leukemia patients that have not responded to other therapies. The results of two phase I clinical trials using STI 571 for chronic myelogenous leukemia (CML) and acute lymphoblastic leukemia (ALL) were reported by Brian Druker, MD, of the Oregon Health Sciences University in Portland, at the ASH meeting. The trials were conducted in collaboration with M.D. Anderson Cancer Center in Houston, Novartis Pharmaceuticals in East Hanover, New Jersey, and the University of California at Los Angeles.
NEW YORK-Acute myelogenous leukemia (AML) is an aggressive disease. But improved diagnosis with cytogenetic examinations and other special studies have made it possible to select the most effective induction therapy, Frederick R. Appelbaum, MD, told patients at a teleconference sponsored by Cancer Care Inc. and the Leukemia Society of America.
CHICAGO-Using all-trans retinoic acid (ATRA) to both induce remission and for maintenance makes acute promyelocytic leukemia (APL) potentially the most curable subtype of adult acute myeloid leukemia, said Martin S. Tallman, MD, at the American Society of Hematology meeting.
BETHESDA, Md-The Oncologic Drugs Advisory Committee (ODAC) has recommended that the FDA approve Targretin capsules (bexarotene, Ligand Pharmaceuticals) for the treatment of advanced cutaneous T cell lymphoma (CTCL) but not for early stage CTCL.
NEW ORLEANS-STI 571, an investigational drug for the treatment of chronic myelogenous leukemia (CML), produced complete hematologic responses in all patients receiving higher doses, according to preliminary analysis of phase I data presented at the 41st Annual Meeting of the American Society of Hematology (ASH) (see illustration ). All participants had failed interferon-alfa therapy.
High-dose therapy with hematopoietic progenitor-cell transplantation plays a key role in the treatment of Hodgkin’s disease and the non-Hodgkin’s lymphomas. First and foremost, transplantation is used as a salvage treatment for those who relapse or do not achieve a complete remission with first-line chemotherapy. Carefully selected patients with poor prognostic features may benefit from the incorporation of high-dose therapy and transplant into their initial treatment programs. Despite a myriad of trials, many pivotal questions regarding the appropriate application of high-dose therapy with transplantation to the lymphoid malignancies remain unsettled, including the role of allogeneic transplantation and the optimal timing of transplant for patients with poor prognostic indicators. Phase III studies are required to address these issues; these trials will demand the active commitment of concerned transplanters and referring hematologists and oncologists. Although autologous transplantation has been the preferred approach for the majority of patient subgroups, new approaches to allogeneic transplantation that have diminished toxicity may pave the way for a greater role for allogeneic grafting in the lymphoid diseases.

Data published in a recent issue of Blood suggest that valspodar (Amdray), a multidrug resistance modulator being developed by Novartis Pharmaceuticals Corporation, may show promise in treating certain patients with acute myelogenous leukemia
MIAMI BEACH, Florida-Cutaneous T-cell lymphomas (CTCL) often cause severe facial disfigurement that adversely affects a patient’s quality-of-life. A new fusion protein, DAB389IL-2 (denileukin diftitox, Ontak), has produced significant response rates in heavily pretreated relapsed CTCL patients and improved quality of life, Madeleine Duvic, MD, said at the American Society of Hematology (ASH) annual meeting.
The combination of fludarabine and mitoxantrone (FM) has been shown to be an effective regimen for indolent lymphoma (J
MIAMI BEACH-Long-term follow-up of 23 patients with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) in first complete remission showed a relatively low relapse rate at 3 years when treated with allogeneic bone marrow transplant from HLA-matched siblings, D.S. Snyder, MD, reported at the American Society of Hematology (ASH) annual meeting.
TUCSON-Cyclosporine (Sandimmune) significantly reduces resistance to daunorubicin (Cerubidine), prolongs the duration of remission, and improves overall survival of patients with high-risk acute myelogenous leukemia (AML), Alan F. List, MD, of the University of Arizona, said at the ASH meeting. Dr. List’s observations were based on a randomized trial conducted with the Southwest Oncology Group.
SEATTLE-Preliminary phase II data show that CMA-676, an engineered human anti-CD33 antibody linked to calicheamicin, a potent cytotoxic agent, produced an objective response in 10 of 23 patients (43%) with acute myelogenous leukemia in first relapse after initial chemotherapy. Six responders went on to allogeneic bone marrow transplant.
