Arm group label:
Treatment w/Mosunetuzumab + Zanubrutinib
Summary:
To assess the efficacy and safety of mosunetuzumab combined with zanubrutinib in patients
with relapsed or refractory MZL.
Detailed description:
Primary Objectives:
To determine the safety and efficacy of mosunetuzumab in combination with zanubrutinib as
determined by best complete response (CR) rate of combination treatment for patients with
relapsed or refractory marginal zone lymphoma (MZL).
Secondary Objectives:
To determine best overall response rate (ORR), duration of response (DOR), time to next
treatment, progression-free survival (PFS), overall survival (OS), and evaluation of
tolerability of mosunetuzumab and zanubrutinib as treatment for patients with
relapsed/refractory MZL.
Exploratory Objective:
To determine the impact of total metabolic tumor volume to ORR, CR rate and survival
outcomes
To determine the biomarkers that correlates with response and mechanisms of resistance to
mosunetuzumab and zanubrutinib in relapsed/refractory MZL.
To determine the surrogate endpoint for future trials in MZL.

monoclonal antibody Stage II, III or IV disease Age ≥18 years. Because no dosing or
adverse event data are currently available on the use of mosunetuzumab and zanubrutinib
combination in patients <18 years of age, children are excluded from this study.

have a potential teratogenic risk.
Agree to refrain from donating blood while on study treatment, during dose interruptions
and for at least 28 days following the last dose of study treatment.
Agree not to share study medication with another person. Sign an informed consent
document indicating that they understand the purpose of and procedures required for the
study, including biomarkers, and are willing to participate in the study.
Females must agree to abstain from breastfeeding during study participation and for at
least 12 months after treatment discontinuation.
Females of childbearing potential (FCBP§) must:
Have one negative pregnancy tests via serum or urine prior to starting study therapy.
Not engaging in sexual activity for the total duration of the trial and the drug washout
period is an acceptable practice. Otherwise, she must agree to use, and be able to comply
with two forms of contraception: one highly effective, and one additional effective
(barrier) measure of contraception without interruption 28 days prior to starting
mosunetuzumab, during the study treatment (including dose interruptions), and for at
least 3 months after the completion of treatment.
Approved methods of birth control are as follows: Hormonal contraception (i.e. birth
control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device
(IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or
injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity
for the total duration of the trial and the drug washout period is an acceptable
practice; however periodic abstinence, the rhythm method, and the withdrawal method are
not acceptable methods of birth control. Should a woman become pregnant or suspect she is
pregnant while she or her partner is participating in this study, she should inform her
treating physician immediately.
Male subjects must:
A male subject who is sexually active with a female with reproductive potential must
agree to use a barrier method of birth control, eg, either condom with spermicidal
foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or
cervical/vault caps) with spermicidal foam/gel/film/cream/ suppository (including dose
interruptions), even if they have undergone a successful vasectomy, from the time of
signing consent and for at least 3 months after the completion of treatment. A male
subject must agree not to donate sperm or semen, while taking treatment, during breaks
(dose interruptions), and for at least 3 months after the completion of treatment.
Sign an informed consent document indicating that they understand the purpose of and
procedures required for the study, including biomarkers, and are willing to participate
in the study.
The investigator is responsible for: ensuring that the patient understands the potential
risks and benefits of participating in the study; ensuring that informed consent is given
by each patient, this includes obtaining the appropriate signatures and dates on the
informed consent document prior to the performance of any study procedures and prior to
the administration of study treatment; answering any questions the patient may have
throughout the study and sharing in a timely manner any new information that may be
relevant to the patient's willingness to continue his or her participant in the trial.
Subjects will undergo a brief physical exam including a brief exam to determine cognitive
review. No one without capacity to personally consent will be enrolled. Patients have
medical decision-making capacity if they can demonstrate understanding of the situation,
appreciation of the consequences of their decision, and reasoning in their thought
process, and if they can communicate their wishes.
A determination of lack of decision-making capacity shall be made after an appropriate
medical evaluation that concludes there is little or no likelihood that the participant
will regain decision-making capacity in a reasonable period of time.
§A FCBP is a female who: 1) has achieved menarche at some point, 2) has not undergone a
hysterectomy or bilateral oophorectomy, or 3) has not been naturally postmenopausal
(amenorrhea following cancer therapy does not rule out childbearing potential) for at
least 24 consecutive months (ie, has had menses at any time in the preceding 24
consecutive months).
Exclusion Criteria:

cervical carcinoma in situ without evidence of disease. Any life-threatening illness,
medical condition, or organ system dysfunction which, in the investigator's opinion,
could compromise the subject's safety, interfere with the absorption or metabolism of
lenalidomide capsules, or put the study outcomes at undue risk.
