NK-cell Therapy: Better than a transplant?

GVL without GVHD?

Having Your Cake and Eating It Too

Mandelbrot Part New research findings point to NK (Natural Killer) cells as the most potent cell line capable of GVL (graft-versus-leukemia), but these cells do not seem to do as much GVHD (Graft-Versus-Host-Disease). A brand new clinical trial launched at the University of Minnesota uses haplo NK cells in an attempt to get the much desired GVL, while steering clear of the dreaded GVHD. This is an early stage trial but one with sufficient potential that CLL Topics has decided to sponsor it and fund part of its cost. Most of our patients will have access to haplo donors, since children are by definition haplo match to their parents. For late stage patients unsure about submitting to the risks of a stem cell transplant, or who do not have suitable adult donors, this NK cell clinical trial may be a good fit. Our review NK-cell Therapy: Better than a transplant? describes the background, rationale and advantages of this approach, as well as providing inclusion criteria and contact information.

Reports on an Umbilical Cord Stem Cell Transplant

Read What Chaya and Harvey Say about His Transplant

Harvey's Journal Logo We have launched a new online journal, detailing the background and stages of a cord blood stem cell transplant for our case study patient, Harvey. Please do visit. Your comments are welcome. (2/25/08)


MUD Transplants at the NCI

NIH Will Pick Up the Tab

Brand New Protocol Makes Its Debut

hematopoeitic stem cells The NCI has just announced a new mini-allo MUD stem cell transplant clinical trial designed to evaluate the relative efficacy of two different methods of handling GVHD (graft versus host disease). Patients should take additional – and particular – notice of the fact that the NCI will pay for the entire protocol – from cytoreduction to transplant and post-transplant monitoring. Patients with a well matched unrelated donor (MUD) but without adequate insurance will find this trial may open a door that is otherwise closed. To find out more please read MUD Transplants at the NCI. (1/18/08)


Opinion: What Say You, Dr. Expert?

Viewpoints from Noted CLL Experts

Making Sensible Decisions About Stem Cell Transplants

hematopoeitic stem cells The clinical research community is slowly coming to grips with the question of when a stem cell transplant makes sense in CLL. The mortality and GVHD risks associated with transplants are definite deterrents but there are substantial survival risks, too, in not taking definitive action when faced with aggressive, poor-prognostic or refractory disease. Four of our favorite CLL experts from major research centers have been generous in sharing their personal viewpoints on the question. You can read their opinions in our article, "What Say You, Dr. Expert?" (9/10/07)


Cord Blood Transplants

Review of the State of the Art

Greatly Improved Odds: but Transplant Mortality Remains

rainbow The state of the art in cord blood transplants has come a long way in the past few years. Originally attempted only with children because of the limited stem cell dose available in umbilical cords, these procedures have evolved to include double cords and are now producing results in adults comparable with those from adult donor transplants. We review the results from the University of Minnesota and elsewhere and explain the concepts involved in our article titled Cord Blood Transplants: State of the Art. For many patients who do not have a matched sibling or unrelated adult donor, cord blood transplants are the lifeline of hope for a durable remission and perhaps a cure. (8/11/07)


Catch 22 — The Transplant Minefield

Balancing the Chance of a Real Cure Against Transplant Mortality Risk

Expert Opinions Diverge on Timing

dial Many CLL patients with adverse prognostic indicators know that sooner or later they will have to face the prospect of a stem cell transplant. Current research shows improving results from mini-allo transplants for CLL patients, especially if they have clean remissions and are otherwise in good health going into the transplants. While this might argue for early, elective transplants for some patients the mortality risks are still significant and there is as yet no consensus among transplant experts on timing and exhaustion of other therapy options. To understand the issues involved, please read our case study of an anonymous patient volunteer in Catch 22 — The Transplant Minefield . (7/4/07)


GVHD Developments

A New Agent to Improve Chances of Survival

GVHD: A Pebble in the Transplant Shoe

art glass While mini allo stem cell transplants hold the promise of a cure for this disease, the risk of mortality and graft versus host disease have been major deterrents to using this technique in high risk CLL patients. New results from research in managing the worst effects of GVHD point the way to improved survival and transplant related symptoms. We review encouraging results reported by the team at the Fred Hutchinson Cancer Research Center in our article GVHD: A Pebble in the Transplant Shoe and explain why this could be very important to CLL patients with poor prognostics. (5/3/07)


Almost Free Stem Cell Transplants

NIH Clinical Trial for Sibling Donor Transplants

A Unique Opportunity

stem cells The National Institutes of Health in Bethesda, MD are conducting a clinical trial for sibling donor transplants that may offer a unique therapeutic opportunity for CLL patients with aggressive disease and poor prognostics. In this article, Stem Cell Transplants – Free of Charge (Almost!), we review the background and rationale for this clinical trial, as well as give you contact information. Potential participants both in the US and overseas should carefully consider this unique opportunity that might otherwise be out of their reach for financial reasons. (1/3/07)


Poor Prognostics

The Road to a Stem Cell Transplant

Greg's Story: A Cautionary Tale

fractal blue rose Greg's Story is a case study based on the notes of an anonymous patient. It is a cautionary tale about the dangers inherent in a relapse in the face of poor prognostics. Delaying the decision to seek a mini-allo transplant, the only known cure at this point for poor prognostic disease, can result in that choice being removed suddenly. You will learn why Greg feels poor prognosis CLL should be taken very seriously and why a decision on pursuing a mini-allo should be made early in the process. (12/17/06)


Graft versus Host Disease

Controlling this Killer is the Holy Grail of Transplants

GVHD in Allogeneic Transplants

transplants Graft-versus-host-disease (GVHD) is an example of systemic and potentially life threatening inflammation. It is one of the major causes of death in stem cell transplants. Controlling GVHD is the holy grail of all transplant researchers. Our article, Graft versus Host Disease, discusses the causes of GVHD and some commonsense things you can do to protect yourself.

Allogeneic Stem Cell Transplants

The Only Real Cure Out There, for Now

New Papers Spell Out the Chances for Success

stem cells As the years go by, survival statistics from allogeneic stem cell transplants performed in the past have been accumulating. We review the surprising results reported in two newly published papers from the Hutch. Read more in our article, The Only Real Cure Out There, for Now. (7/19/05)


Matching Made Simple

Is a Bone Marrow Transplant in Your Future?

Allogeneic Stem Cell Transplants Work Better with Closer Matches

jigsaw HLA matching of the potential donor with the recipient is the first step in allogeneic stem cell transplants, whether the stem cells are obtained from an adult donor or from umbilical cord blood. With increasing frequency, stem cell transplantation is viewed as an early alternative for those with aggressive disease or high risk profiles, especially for younger patients. Familiarity with the concept of tissue typing will be useful as you embark upon the transplant journey. To take some of the mystery out of this process we present Matching Made Simple. (12/17/04)


AMD3100: Stem Cell Mobilization for Transplants

New Agent in Clinical Trial

Harvesting Sufficient Stem Cells for Auto BMTs

stem cells The techniques of stem cell transplantation have been improving over the years. AMD3100, a new CXCR4 blocker originally developed for AIDS treatment, shows promise in mobilizing stem cells for harvesting in both autologous and allogeneic stem cell transplantation procedures. (12/10/03)


Primer on Bone Marrow Stem Cell Transplants

All or Nothing Approaches

Transplant of Allogeneic Hematopoietic Stem Cells Offers Hope of Cure

stem cells In this article, Primer on Bone Marrow Stem Cell Transplants, we review the basics of stem cell transplants, both autologous and allogeneic. These are complex, protracted, multi-step procedures with high risk and high costs. However, techniques have been progressively refined and the results can be impressive, especially with allogeneic transplants if a matching donor is available. (5/23/03)
