1989

Leukaemia Busters is founded

by parents of children with leukaemia and lymphoma whose children were undergoing treatment in the Wessex Children’s Cancer Unit at Southampton General Hospital. One of those sets of parents, Drs David and Bee Flavell were already actively pursuing research in their laboratory at Southampton General Hospital, making antibodies against leukaemia and lymphoma cells when their only son, Simon was diagnosed with T-cell acute lymphoblastic leukaemia in 1988.

1990

Simon Flavell dies

with T-cell acute lymphoblastic leukaemia after almost two years of intensive chemotherapy and radiotherapy.

1990

Major fundraising campaign is launched

by Southampton-based local Echo newspaper to raise £150,000 to build a new laboratory for research on developing antibody-based treatments for children with incurable forms of leukaemia and other blood related cancers. The new laboratory, it was universally agreed, should be named The Simon Flavell Leukaemia Research Laboratory.

1991

Simon Flavell Leukaemia Research Lab opens

and development work on the charity’s first antibody-based drug, BUSAP begins immediately.

1992

First Charity registration

with the Charity Commission as a charitable trust Registration No 1010957.

1993

Official opening of the Simon Flavell Laboratory

at Southampton General Hospital by Gary and Michelle Lineker who shortly after become the charity’s first patrons and remain so for the next eleven years.

1996

First clinical trial begins

with BUSAP, an immunotoxin targeting B-cell lymphoma in adult patients to prove safety before proceeding to a trial in children with relapsed acute lymphoblastic leukaemia.

1998

Drug development work

on second antibody-based drug OKSAP begins for patients with myeloma and acute lymphoblastic leukaemia.

2000

Second clinical trial begins

with OKSAP in adults with myeloma again to demonstrate safety in adults before progressing to a clinical study in children with relapsed leukaemia.

2001

Third clinical trial begins

at eleven children’s cancer centres around the UK with BUSAP for children with relapsed B-cell acute lymphoblastic leukaemia. This was to be the first time an antibody-based drug of this type had been used in children with leukaemia in the UK.

2003

Clinical Trials Unit established

to deal with new regulations and requirements following a new European Clinical Trials Directive.

2004

New European rules

2004 New European rules make clinical trial work too expensive for the charity to afford and all promising clinical trial work is subsequently halted

2004

Research and development work

is prioritised to discover ways of increasing the effectiveness of the charity’s portfolio of five immunotoxin drugs and to explore alternative ways of boosting immunity to act in concert with the immunotoxin drugs already developed by the charity.

2014

Registration as a Charitable Incorporated Organisation

with the Charity Commission to give increased flexibility and to meet the needs of the charity well into the future Charity registration No 1157147.

2014 onwards

Research and development work

continues in the Simon Flavell Laboratory and new discoveries are made and published in international scientific and medical journals.

2024

The Simon Flavell laboratory closes

after 36 years of continuous research and development supported by Leukaemia Busters and other medical research charities.

2025

Establishment of Simon Flavell Research Fellowships

to support research for early career scientists to pursue research on the immunotherapy of leukaemia and lymphoma using antibodies and other immunologically-based methods. Read More.
