Cd40 Ligand Therapy of Lymphoma PatientsUniversity of Texas M.D. Anderson Cancer Center, Houston, TX To the Editor:Vonderheide et al1 reported their experience with recombinant human CD40 ligand (CD40L) in cancer patients. In that phase I study, nine patients with non-Hodgkins lymphoma (NHL) were included. The authors reported that one patient with NHL had a transient partial remission. Because of the controversy surrounding the role of CD40 ligand in B-cell lymphoid tumors,2 it would be important that the authors provide detailed information on all nine lymphoma patients enrolled on this study.
We and others have reported that soluble CD40L may enhance the survival of freshly isolated malignant B cells and in some cases may enhance the proliferation of these cells in vitro.3-8 This effect has been attributed to the activation of NF-
Providing this information would be greatly appreciated by investigators who are interested in further evaluating the CD40L pathway for the treatment of B-cell NHL. REFERENCES

Response
Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA In Reply:Dr Younes raises several interesting questions regarding our phase I study of recombinant human CD40 ligand (rhuCD40L) in cancer patients.1 Table 1 outlines further information regarding the nine patients with non-Hodgkins lymphoma (NHL) treated with this agent.
The patient with a partial response was a 52-year-old woman with large-cell immunoblastic T-cell lymphoma who at study entry had progressive disease (multiple skin lesions and lymphadenopathy). She had previously received chemotherapy, radiation therapy, and cytokine therapy with varying clinical responses, including prior partial responses and one complete response to radiation therapy. One month before study entry, she had progressive disease despite 2-deoxycoformycin. After the first course of rhuCD40L, the patient achieved a partial response, as evidenced by regression of skin lesions and reduced lymphadenopathy. After receiving a second course of rhuCD40L, the patient developed tiny, new skin lesions and a bone marrow biopsy showed relapse of her T-cell NHL. The patient was subsequently treated with chemotherapy but had died by the time of the 9-month poststudy follow-up. Tumor cell CD40 expression was not evaluated in this patient. Among the other NHL patients, six of eight patients had progressive disease after a single course of rhuCD40L, and two patients (nos. 2051 and 2553, Table 1) had stable disease after one course but progressive disease after two courses. Serum CD40L levels were not measured. Overall, we believe the data do not suggest that treatment of NHL patients with rhCD40L at this schedule resulted in acceleration of progressive disease.
