Pilot Study of Tocilizumab in Patients With Symptomatic Kaposi Sarcoma Herpesvirus (KSHV) - Associated Multicentric Castleman Disease
Background:
- KSHV-associated multicentric Castleman disease (KSHV-MCD) is caused by a herpes virus known
as KSHV. This disease can also cause several other cancers, including Kaposi sarcoma. People
with KSHV-MCD often have symptoms like fever, weight and muscle loss, and fluid in the legs
or abdomen. Tocilizumab may be able to block the chemicals in the body that cause KSHV-MCD
symptoms. Researchers want to test this drug and other anti-virus drugs to find the best
combination of drugs to treat KSHV-MCD.
Objectives:
- To test the effectiveness of tocilizumab with and without other anti-virus drugs for
KSHV-MCD.
Eligibility:
- People at least 18 years of age who have KSHV-MCD and have certain symptoms and blood
abnormalities caused by their KSHV-MCD.
Design:
- Participants will be screened with a medical history and physical exam. They will also
have blood tests, and a skin biopsy.
- Participants will have tocilizumab injections every 2 weeks for up to 12 weeks. They
will provide daily blood samples for the first 3 days of treatment.
- After the sixth dose, participants will be monitored for 4 weeks to check for possible
side effects.
- Those whose KSHV-MCD does not improve or worsens during the study may have tocilizumab
combined with two other anti-virus drugs, zidovudine and valganciclovir. These drugs are
pills that will be taken four times a day for 5 days out of every 2 weeks.
- Blood, urine, and saliva samples will be collected throughout the study.

BACKGROUND:
- Kaposi sarcoma herpesvirus-associated multicentric Castleman disease (KSHVMCD) is a rare
lymphoproliferative disorder that develops predominantly in HIVinfected patients.
Patients often have symptoms from interleukin-6 (IL-6), KSHVencoded viral IL-6 (vIL-6),
and other cytokines
- Goals of therapy include rapid resolution symptoms and elimination of reservoirs of
KSHV-infected plasmablasts.
- Tocilizumab is a humanized anti-IL-6 receptor (gp80) antibody with activity against MCD
unrelated to KSHV (KSHV-negative MCD). While tocilizumab does not directly affect vIL-6
signaling or other KSHV driven pathologic processes, IL-6 overproduction plays a major
role in symptoms in KSHV-MCD, and blocking IL-6 may be sufficient to treat this disorder
by blocking autocrine and paracrine stimulation. Combination with zidovudine (AZT) and
valganciclovir (VGC), agents that target KSHV replication, have virus-activated
cytotoxic activity, and are active in KSHV-MCD may be useful and necessary in some
patients.
OBJECTIVES:
- Primary objective: Estimate clinical benefit of tocilizumab 8mg/kg every 2 weeks for up
to 12 weeks in patients with symptomatic KSHV-MCD using a modified KSHVMCD Clinical
Benefit Response Criteria
- Secondary objectives:
- Estimate best clinical, biochemical, radiographic, and overall responses in patients
with KSHV-MCD treated for up to 12 weeks with tocilizumab 8mg/kg every 2 weeks using the
prior NCI KSHV-MCD Response Criteria.
- In patients with inadequate response to tocilizumab monotherapy: explore preliminarily
the activity of tocilizumab 8mg/kg every 2 weeks, combined with AZT 600 mg orally q6
hours and VGC 900 mg orally q12 hours on days 1-5 of a 14-day cycle
- Evaluate safety and tolerability of tocilizumab alone and combined with AZT/VGC
- Evaluate the effect of tocilizumab on the pharmacokinetics of antiretroviral agents that
are CYP3A4 substrates in patients with symptomatic KSHV-MCD
- Evaluate progression-free and overall survival of patients treated with tocilizumab and
tocilizumab/AZT/VGC
- Evaluate of effect of tocilizumab on KS
Eligibility
- Pathologically confirmed KSHV-associated MCD
- Age greater than or equal to 18
- At least one clinical symptom and at least one laboratory attributable to KSHV-MCD
- ECOG performance status less than or equal to 2
- No life- or organ-threatening manifestations of MCD
- Patients requiring therapy for rheumatoid arthritis will be excluded
- HIV-infected patients must agree to continue or start combination antiretroviral therapy
DESIGN:
- Open label, single center pilot study. Eligible patients receive tocilizumab 8 mg/kg
every 2 weeks for up to 12 weeks. In addition, patients requiring treatment
intensification also receive AZT 600 mg orally q6 hours and VGC 900 mg orally q12 hours
on days 1-5 of a 14-day cycle.
- Sample size 17: two stage phase II design, alpha equals beta equals 0.10, ruling out
<20% KSHV-MCD Clinical Benefit Partial Response or better with tocilizumab and targeting
a >50% KSHV-MCD Clinical Benefit Partial Response or better requires 10 in the first
stage. 0-2 of 10 major response: stop accrual, 3+/10: accrual to 17 total.
- Responses evaluated by KSHV-MCD Clinical Benefit Response Criteria and NCI KSHV-MCD
criteria under prospective evaluation.
- Safety and tolerability evaluated using current CTCAE.
