INTRODUCTION 
 
2.1 
STUDY RATIONALE  
 
Alzheimer’s disease (AD) is a gradually progressive neurodegenerative disease that is the leading cause 
of dementia world-wide. Currently available treatments for AD, which include cholinesterase inhibitors 
(donepezil, rivastigmine, and galantamine) and a low-affinity NMDA receptor antagonist (memantine), 
have only modest effects on the symptoms of the disease, and do not prevent disease progression. 
While the underlying cause of Alzheimer’s disease remains unknown, there has been extensive evidence 
that mitochondrial dysfunction (Perez Ortiz and Swerdlow 2019) and neuroinflammation (Heneka et al. 
2015) play a significant role in the pathogenesis of AD.

Nicotinamide adenine dinucleotide (NAD) is a co-enzyme found in all living cells. NAD levels decrease 
during aging and are involved in age-related metabolic decline (Imai and Guarante 2014, Verdin 2015). 
CD38 is a multi-functional enzyme that hydrolyzes NAD, and is also involved in cell signaling. CD38 levels 
increase in tissues with age and correlate with NAD decline (Camacho-Pereira et al. 2016)  In CD38 
knockout mice, tissue levels of NAD are significantly increased (Askoy et al. 2006). When CD38 knockout 
mice were crossed with APPswePS1ΔE9 transgenic mice to generate Alzheimer’s pathology-prone CD38-
deficient mice, they exhibited significant reductions in amyloid-beta (Aβ) plaque load and soluble Aβ 
levels, and this correlated with improved spatial learning. Furthermore, neuronal cultures derived from 
these mice secreted less Aβ, and this reduction was mimicked when APPswePS1ΔE9 neuronal cultures 
were treated with inhibitors that blocked CD38 enzyme activity or the signaling pathways controlled by 
CD38‐derived metabolites, suggesting that CD38 may be a novel target for AD treatment (Blacher et al. 
2015).  
 
CD38 expression on CD8+ T-cells, indicative of activation, is significantly increased in the blood of early 
AD patients as compared with age-matched controls, and activated T-cells are capable of trafficking into 
the central nervous system and exerting cytotoxic effects (Zhang et al. 2013). CD38 significantly affects 
regulation of the amount and function of activated microglia, with important consequences for injury 
and repair processes in the brain (Mayo et al. 2008). 
 
2.2 
BACKGROUND  
 
Daratumumab is a human IgG1k monoclonal antibody that targets CD38. It is FDA-approved for the 
treatment of multiple myeloma. Daratumumab has broad-ranging immunomodulatory effects on 
nonplasma cells that express CD38 (Krejcik et al. 2016). Daratumumab is able to cross the blood-brain 
barrier (Vercruyssen et al. 2018). 
 
A subcutaneous (SC) formulation of daratumumab with recombinant human hyaluronidase enzyme 
PH20 (rHuPH20) has been shown to be well tolerated, with low rates of infusion-related reactions and 
similar efficacy to intravenous (IV) daratumumab in patients with multiple myeloma. (Usmani et al. 
2016, Chari et al. 2018). Furthermore, each dose of daratumumab SC can be administered over 3 to 5 
minutes, as compared with median first, second, and subsequent IV infusion durations of 7.0, 4.3, and 
3.4 hours, respectively. 
 
2.3 
RISK/BENEFIT ASSESSMENT   
   
2.3.1 KNOWN POTENTIAL RISKS  
  
While the package insert for the IV formulation of daratumumab (Darzalex) is provided for reference, it 
should be noted that it includes data for adverse effects in patients with multiple myeloma who were 
treated with various combination chemotherapy regimens. Furthermore, multiple myeloma is a 
hematological malignancy that can predispose patients to infection, anemia, thrombocytopenia, and 
leukopenia. As per the package insert, the safety data reflecting exposure to IV daratumumab 16 mg/kg  
monotherapy in 156 adult patients with relapsed and refractory multiple myeloma treated in three 
open-label, clinical trials, with median duration of exposure of 3.3 months (range: 0.03 to 20.04

months), are listed below. Serious adverse reactions were reported in 51 (33%) patients. The most 
frequent serious adverse reactions were pneumonia (6%), general physical health deterioration (3%), 
and pyrexia (3%). Adverse reactions resulted in treatment delay for 24 (15%) patients, most frequently 
for infections. Adverse reactions resulted in discontinuations for 6 (4%) patients. Adverse reactions 
occurring in at least 10% of patients are presented in Table 1. Table 2 describes Grade 3–4 laboratory 
abnormalities reported at a rate of ≥10%.

Infusion Reactions: 
In clinical trials of IV daratumumab (monotherapy and combination treatments; N=1166) the incidence 
of any grade infusion reactions was 40% with the first infusion, 2% with the second infusion, and 4% 
with subsequent infusions. Less than 1% of patients had a Grade 3 infusion reaction with second or 
subsequent infusions. Grade 4 infusion reactions were reported in 2/1166 (0.2%) of patients. 
The median time to onset of a reaction was 1.4 hours (range: 0 to 72.8 hours). The incidence of 
infusion modification due to reactions was 37%. Median durations of infusion for the 1st, 2nd, and 
subsequent infusions were 7.0, 4.3, and 3.4 hours respectively. Severe infusion reactions included 
bronchospasm, dyspnea, laryngeal edema, pulmonary edema, hypoxia, and hypertension. Other adverse 
infusion reactions included nasal congestion, cough, chills, throat irritation, vomiting and nausea. 
 
Herpes Zoster Virus Reactivation: 
In IV daratumumab monotherapy studies, herpes zoster was reported in 3% of patients.  
 
Hepatitis B Virus Reactivation: 
As of 15 November 2018, daratumumab has been administered to approximately 4,407 patients in the 
setting of clinical trials, with an estimated world-wide post-marketing exposure of 34,316 person-years.  
HBV reactivation, including fatal cases, has been observed in association with daratumumab.  Following 
a thorough, cross-program review of clinical trial and post-marketing reports, Janssen has determined 
that HBV reactivation is an important identified risk and adverse drug reaction associated with 
daratumumab.   
 
Interference with Indirect Antiglobulin Test (indirect Coombs test): 
Daratumumab binds to CD38 found at low levels on red blood cells (RBCs) and may result in a positive 
indirect Coombs test. Daratumumab-mediated positive indirect Coombs test may persist for up to 6 
months after the last daratumumab infusion. It should be recognized that daratumumab bound to RBCs 
may mask detection of antibodies to minor antigens in the subject’s serum. The determination of a 
subject’s ABO and Rh blood type are not impacted. 
 
Daratumumab SC: 
The subcutaneous route of administration for daratumumab was first evaluated by the Janssen Research 
& Development in Study MMY1004 (PAVO), a Phase 1b, open-label, multicenter, 2-part dose escalation 
study in patients with relapsed or refractory multiple myeloma. In this ongoing study, daratumumab SC 
(Dara-SC) is being administered according to the approved monotherapy schedule [i.e., weekly for 8 
weeks, every 2 weeks for an additional 16 weeks, and every 4 weeks thereafter until progressive disease 
(PD) or unacceptable toxicity]. The PAVO study assessed the safety, pharmacokinetics, and efficacy of SC

administration of daratumumab plus rHuPH20 (DARA-PH20). After a median follow-up of 6.5 months 
(clinical cutoff date of 13 Dec 2017), 25 patients received at least 1 dose of 1800 mg Dara-SC in Study 
MMY1004. The injection-related reaction rate was 16% and consisted of Grade 1 or 2 chills, dyspnea, 
sneezing, and allergic rhinitis, and two Grade 3 events of hypertension. None of the injection-related 
reaction events led to treatment discontinuation. Injection-site reactions occurred in 12% (n=3) of 
patients, all were Grade 1. The events were discoloration/injection site induration, hematoma, and 
erythema. The overall response rate (ORR) was 52% with 28% very good partial response rate (VGPR). 
Median progression-free survival (PFS) has not been reached. The efficacy and adverse event profile are 
consistent with that of IV daratumumab with a lower rate of injection-related reactions. Based on these 
clinical data and supported by the pharmacokinetic profile of Dara-SC, the safety and efficacy of Dara-SC 
appear equivalent to and may be better than Dara-IV. Together these findings suggest that co-
formulated SC daratumumab 1800 mg plus rHuPH20 is well tolerated and achieves response rates 
similar to those observed with daratumumab administered by IV infusion. In addition, the daratumumab 
SC administration has an added benefit of shorter administration time (3 to 5 minutes for SC 
daratumumab injection versus a median duration of 7 hours when administered by IV infusion). 
Please refer to the Investigator’s Brochure (IB) for more detailed safety data about daratumumab. 
 
Known potential risks of concurrent protocol-specific medications: 
 
1. Side effects of dexamethasone may include nausea, vomiting, heartburn, headache, dizziness, 
trouble sleeping, appetite changes, increased sweating, high blood sugar, mood swings, bleeding 
from the stomach, swelling of the hands or feet, and bone damage. 
2. The most common adverse reactions in adult patients treated with acetaminophen (Tylenol) are 
nausea, vomiting, headache, and insomnia. 
3. Side effects of diphenhydramine (Benadryl) may include sleepiness, confusion, dizziness, 
incoordination, dry mouth, blurred vision, upset stomach, constipation, and difficulty urinating. 
4. The most common adverse reactions to montelukast (incidence >5% and greater than placebo, 
listed in descending order of frequency) are upper respiratory infection, fever, headache, 
pharyngitis (sore throat), cough, abdominal pain, diarrhea, otitis media (ear infection), influenza, 
rhinorrhea (runny nose), and sinusitis (inflammation of sinuses).  
5. Side effects of acyclovir may include nausea, vomiting, dizziness, diarrhea, sleepiness, and 
confusion. 
 
2.3.2 KNOWN POTENTIAL BENEFITS  
 
While daratumumab is FDA-approved for the treatment of multiple myeloma, and is under study for the 
treatment of other hematological malignancies, it has not previously been studied for the treatment of 
Alzheimer’s disease. There is a rationale to suggest a potential for direct benefit to AD subjects. 
However, this study is exploratory, and there is no guarantee of direct benefit. The results of this study 
may provide generalizable knowledge about the potential utility of this strategy for the treatment of 
Alzheimer’s disease, and should provide more specific data regarding the benefit-risk ratio of 
daratumumab in this patient population.

2.3.3 ASSESSMENT OF POTENTIAL RISKS AND BENEFITS  
 
As there are no currently available disease-modifying treatments for AD, there is an adequate rationale 
to explore the potential efficacy of daratumumab in this small open-label study. The safety profile of 
daratumumab has been well-characterized in patients with multiple myeloma. Since the AD subjects to 
be enrolled in this study will be otherwise healthy, without history or evidence of malignancy, cardiac, 
pulmonary, or other significant medical illnesses or laboratory abnormalities, we expect the risk of 
adverse hematological effects or infectious complications to be lower than in patients with multiple 
myeloma. In view of the potential for daratumumab to interfere with the Indirect Antiglobulin Test 
(indirect Coombs test), and mask detection of antibodies to minor antigens in the subject’s serum, type 
and screen will be sent prior to treatment initiation. To minimize the risk of post-infusion reactions, 
individuals with a history of asthma or chronic obstructive pulmonary disease will be excluded, and 
subjects will be premedicated with montelukast 10 mg orally 1 to 3 hours prior to the first dose of 
daratumumab,  diphenhydramine 25 mg orally 1 to 3 hours prior to each dose, acetaminophen 1000 mg 
orally 1 to 3 hours prior to each dose, and dexamethasone 20 mg orally 1 to 3 hours prior to the first 3 
doses, 10 mg orally 1 to 3 hours prior to all subsequent doses, and 4 mg orally the day after each dose. 
To avoid hepatitis B virus reactivation, subjects with serologic evidence of current or prior hepatitis B 
infection will be excluded. To prevent herpes zoster reactivation, patients will also be treated with oral 
acyclovir 400 mg daily beginning the day after the first dose and continuing until 12 weeks after the final 
dose. After the first dose, subjects will have a CBC performed within 48 hours prior to each subsequent 
infusion, and the scheduled infusion will be held if there is evidence of clinically significant anemia, 
neutropenia, leukopenia, or thrombocytopenia. Additional safety laboratory monitoring will include a 
comprehensive metabolic panel (CMP) every 4 weeks.

STUDY DESIGN  
 
4.1 
OVERALL DESIGN 
 
This is an open-label single site pilot study designed to explore whether daratumumab may have a 
clinically meaningful efficacy signal in patients with mild to moderate Alzheimer's disease. During the 
treatment phase, eligible subjects will receive daratumumab SC 1800 mg (daratumumab 1800 mg with 
rHuPH20 30,000 units) subcutaneous infusion over 3-5 minutes (15 mL) once weekly for 8 weeks 
followed by daratumumab SC 1800 mg every 2 weeks for 16 weeks. The primary endpoint is responder 
rate defined as improvement in standard 11-item Alzheimer's Disease Assessment Scale-cognitive 
subscale (ADAS-Cog/11) score of ≥ 4 points at 25 weeks compared with baseline. 
 
4.2 
SCIENTIFIC RATIONALE FOR STUDY DESIGN 
 
This is a pilot study, the purpose of which is explore whether there is a clinically meaningful efficacy 
signal for daratumumab in patients with mild to moderate Alzheimer's disease. The proposed sample 
size of 15 patients is based on feasibility and availability of resources, and not on a formal power 
calculation.

The dosing regimen for this study is based on prior studies in patients with multiple myeloma, since the 
safety profile of that regimen has been well-established. We are using the SC formulation of 
daratumumab because it is associated with substantially lower risk of post-infusion reactions, much 
shorter administration times, and greater convenience for the subjects.

LIFESTYLE CONSIDERATIONS 
 
During this study, participants are asked to abstain from alcohol for 24 hours before the start of each 
dosing or cognitive assessment visit.  
 
5.4 
SCREEN FAILURES 
 
Screen failures are defined as participants who consent to participate in the clinical trial but are not 
subsequently assigned to the study intervention or entered in the study. A minimal set of screen failure 
information is required to ensure transparent reporting of screen failure participants, to meet the 
Consolidated Standards of Reporting Trials (CONSORT) publishing requirements and to respond to 
queries from regulatory authorities. Minimal information includes demography, screen failure details, 
eligibility criteria, and any serious adverse event (SAE).

Individuals who do not meet the criteria for participation in this trial (screen failure) because of an 
MMSE score above the cutoff of 26 may be rescreened after an interval of at least 3 months. 
Rescreened participants should be assigned the same participant number as for the initial screening. 
 
5.5 
STRATEGIES FOR RECRUITMENT AND RETENTION 
 
Subjects will be recruited from our internal database of subjects previously evaluated at the Litwin-
Zucker Research Center who have indicated that they are willing to be contacted about future studies. 
We will also screen subjects who are referred by other providers within Northwell Health Physician 
Partners or by community physicians. We anticipate accrual of 15 subjects over an 18-month enrollment 
period. Due to the inherent nature of the study population, with cognitive impairment due to 
Alzheimer’s disease, it is anticipated that many of these subjects will lack decisional capacity to provide 
informed consent. Accordingly, all potential subjects will be assessed for capacity to provide informed 
consent by one of the study physicians, who are either neurologists or geriatric psychiatrists with 
extensive experience in assessing decisional capacity. If a subject is determined to lack capacity to 
provide informed consent, surrogate consent will need to be obtained from a legally authorized 
representative. In that instance, the subject will also need to provide assent to participate in the study.

STUDY INTERVENTION 
 
6.1 
STUDY INTERVENTION ADMINISTRATION 
  
 
6.1.1 STUDY INTERVENTION DESCRIPTION 
 
Daratumumab, a CD38 antagonist, is a human immunoglobulin G1 kappa (IgG1κ) monoclonal antibody 
(mAb) that binds CD38 expressing cells with high affinity. The subcutaneous formulation is administered 
in combination with recombinant human hyaluronidase (rHuPH20) to facilitate fluid dispersion. 
6.1.2 DOSING AND ADMINISTRATION 
 
During the treatment phase, eligible subjects will receive daratumumab SC 1800 mg (daratumumab 
1800 mg with rHuPH20 30,000 units) given through a syringe and needle by a manual push over 
approximately 3 to 5 minutes once weekly for 8 weeks followed by daratumumab SC 1800 mg every 2 
weeks for 16 weeks. Doses will be administered at alternating locations on the abdomen. The volume of 
1800 mg Daratumumab for SC injection will be approximately 15 mL. In case of significant discomfort 
during manual injection, a slower injection speed may be used or alternatively the total dose may be 
given in 2 separate locations.

To minimize the risk of post-injection reactions, subjects will be premedicated with montelukast 10 mg 
orally 1 to 3 hours prior to the first dose of daratumumab, diphenhydramine 25 mg orally 1 to 3 hours 
prior to each dose,  acetaminophen 1000 mg orally 1 to 3 hours prior to each dose, and dexamethasone 
20 mg orally 1 to 3 hours prior to the first 3 doses, 10 mg orally 1 to 3 hours prior to all subsequent 
doses, and 4 mg daily orally the day after each dose. To prevent herpes zoster reactivation, patients will 
also be treated with oral acyclovir 400 mg daily beginning the day after the first dose and continuing 
until 12 weeks after the final dose. 
6.1.4 MANAGEMENT OF LOCAL INJECTION SITE REACTIONS 
 
Local injection site reactions, such as induration and erythema have been observed following SC 
administration of daratumumab in abdominal SC tissue. The reactions usually resolve within 60 minutes. 
Local injection site reactions can be managed conservatively with cold compresses as need. 
6.1.5 MANAGEMENT OF SYSTEMIC INJECTION-RELATED REACTIONS 
 
Patients should be carefully observed during daratumumab administration. If an injection-related 
reaction develops, then daratumumab administration should be temporarily interrupted.  
 
Patients who experience adverse events during daratumumab administration must be treated for their 
symptoms:  
• Treatment with acetaminophen, antihistamine, or corticosteroids, may be administered as needed.  
• IV saline may be indicated.  
• For bronchospasm, urticaria, or dyspnea, patients may require antihistamines, oxygen, corticosteroids, 
or bronchodilators.  
• For hypotension, patients may require vasopressors.  
 
In the event of a life-threatening reaction (which may include pulmonary or cardiac events) or 
anaphylactic reaction, the patient will be transported to the Emergency Room. Daratumumab should be 
discontinued, no additional daratumumab should be administered to the patient, and the patient must 
be permanently withdrawn from daratumumab treatment. 
 
Injection-related Reactions of Grade 1 or Grade 2: 
If the investigator assesses a Grade 1 to 2 injection-related adverse event to be related to 
daratumumab, then administration of daratumumab should be paused. When the patient's condition is 
stable, daratumumab administration may be resumed at the investigator's discretion.  
 
If the patient experiences a Grade 2 or higher event of laryngeal edema or a Grade 2 or higher event of 
bronchospasm that does not respond to systemic therapy and does not resolve within 6 hours from 
onset, then the patient must be permanently withdrawn from daratumumab treatment.  
 
Injection-related Reactions of Grade 3 or Higher: 
For injection-related reactions (other than laryngeal edema or bronchospasm) that are Grade 3, the 
daratumumab administration must be stopped, and the patient must be observed carefully until

resolution of the adverse event or until the intensity of the event decreases to Grade 1, at which point 
the daratumumab administration may be restarted at the investigator’s discretion. If the intensity of the 
event returns to Grade 3 after restart of the daratumumab administration, then the patient must be 
permanently discontinued from daratumumab treatment. 
 
For injection-related adverse events that are Grade 4, the daratumumab administration must be 
stopped, and the patient permanently discontinued from daratumumab treatment. 
  
Recurrent Injection-related Reactions: 
If a Grade 3 injection-related reaction (or Grade 2 or higher event of laryngeal edema or a Grade 2 or 
higher event of bronchospasm) recurs during or within 24 hours after a subsequent daratumumab 
administration, the subject must be permanently discontinued from daratumumab treatment. 
 
6.2 
PREPARATION/HANDLING/STORAGE/ACCOUNTABILITY 
 
6.2.1 ACQUISITION AND ACCOUNTABILITY 
 
Daratumumab SC will be supplied by Janssen Scientific Affairs, LLC through the drug distribution vendor 
CSM (Clinical Supplies Management Holdings, INC). A drug template request form will be sent to the 
central drug ordering mailbox. During the course of the study, the site will ensure drug inventory is 
checked on a regular basis and enough lead time is given to order, process, and ship drug to the site. 
 
6.2.2 FORMULATION, APPEARANCE, PACKAGING, AND LABELING 
 
Daratumumab SC drug product is a colorless to yellow liquid. Daratumumab SC drug product is co-
formulated at a concentration of 120 mg/mL daratumumab with 2000 U/mL rHuPH20 in an isotonic 
buffer consisting of histidine, sorbitol, methionine, NaCl and polysorbate 20 at pH 5.6. Daratumumab SC 
drug product is supplied as a single-use, sterile, liquid product in a glass vial with stopper and aluminum 
seal with gray plastic flip-off cap.  
 
6.2.3 PRODUCT STORAGE AND STABILITY 
 
The daratumumab vials should be stored in the original carton in a refrigerator at 2˚C to 8˚C and 
must not be utilized after the expiry date printed on the label. The product must be protected from light 
and must not be frozen. Since daratumumab does not contain preservatives, any unused portion 
remaining in the vial must be discarded. 
 
6.2.4 PREPARATION 
 
1. Check the vial to ensure that the vial is labeled for Subcutaneous Administration. 
2. Inspect the expiration date on the carton label before withdrawing the drug from vial to syringe. 
3. After removal of the vial from 2-8˚C storage, equilibrate at room temperature (RT) for at least 30 
minutes.

4. The vial must not be stored at room temperature and room light for more than 24 hours cumulative 
hold (including equilibration time before first vial puncture). 
5. The maximum time at room temperature and room light from vial puncture to administration to the 
subject is 4 hours. 
6. Remove cap and clean top of vial with alcohol wipe. 
7. Gently swirl the vial (do not shake). Inspect the vial for any visible particles. Drug product (DP) 
solution should be colorless to yellow. Do not use the solution if it contains large number of white, 
clear or translucent particles or if it contains dark opaque particles. 
8. Attach disk filter, spike filter or filter needle to the barrel of 20 mL sterile syringe. 
9. Withdraw the entire contents of the RT equilibrated vial through the disk filter, spike filter or filter 
needle. 
10. If a filter becomes clogged or leaking is observed, obtain a new vial and a new filter, and re-start the 
withdrawal process into a new syringe. 
11. Some bubbles/foaming may be observed upon filtration. This is normal and does not affect DP 
quality. If multiple small bubbles/foaming are observed, let the syringe rest for 1 or 2 minutes to let 
the bubbles/foam dissipate. If a small amount of large air bubbles is observed, gently tap the syringe 
with your fingers until the air bubbles rise to the top of the syringe. 
12. Remove and discard the disk filter and transfer needle, mini-spike, or filter needle. 
13. If air bubbles were previously observed, slowly push the plunger up to force the air bubbles out of 
the syringe. 
14. Check the volume in the syringe. 
15. Upon filtration and after removal of air, the syringe must contain at least 15.5 mL. 
16. If it is not possible to adjust to 15.5 mL, a second vial of daratumumab SC 1800 mg DP must be 
allowed to equilibrate at ambient room temperature for at least 30 minutes prior to withdrawal and 
a new filter and a new transfer needle must be used for filtration of the second vial of DP into the 
same syringe (with the previously filtered DP). 
17. A winged infusion set or a syringe tip cap should be attached at this time. 
18. The winged infusion set attached can be adjusted to final dose of 15 mL at this time point. 
Alternatively (if a syringe tip cap is used), adjustment for the final dose can be accomplished in the 
patient care area. 
 
6.2.5 ADMINISTRATION 
 
1. Remind the patient that they should try to remain still during the procedure and to inform the 
Health Care Provider (HCP) if they are uncomfortable. 
2. Check the label on the prepared syringe to confirm that the drug has not passed the expiration time 
and date. 
3. Inspect the syringe for any visible particles: Drug product solution should be colorless to yellow. Do 
not use the solution if it contains large number of white, clear or translucent particles or if it 
contains dark opaque particles. 
4. Ensure the intended dose is available in the syringe: A) If the syringe was delivered with a syringe tip 
cap: remove the syringe tip cap and attach a winged infusion set and adjust to 15mL DP in the

syringe. B) If the syringe was delivered with a winged infusion set: remove needle cap from the 
winged infusion set and confirm that 15mL are present in the syringe. 
5. Select a site for SC injection: abdomen only, ~ 3 inch (7.5 cm) to the right or left side of the navel. 
6. Cleanse the area (~ 2 inch or 5 cm) around the site with alcohol wipe. 
7. Pinch a 2-inch (5 cm) fold of the cleaned skin at the targeted SC injection site between the thumb 
and index finger and hold firmly. 
8. Hold the winged infusion set by the wings. Insert the needle at a 45-degree angle. 
9. Release pinch after the needle is inserted. 
10. Hold the syringe with one hand. With the other, pull back the plunger slightly to check for blood to 
make sure that a blood vessel has not been punctured. 
11. Use one hand to push the plunger rod and another hand to hold the winged infusion set for stability 
during injection. 
12. Deliver the dose by manual injection over approximately 3 to 5 minutes. Try to maintain a constant 
rate during injection. 
13. Check for leakage during administration and monitor the injection site. 
14. If healthcare provider (HCP) feels arm fatigue, delivery may be paused. If the patient is experiencing 
pain the rate of the injection may be slowed down. 
15. If the patient is experiencing pain or significant discomfort that is not alleviated by slowing down, 
the injection a second injection site may be chosen on the opposite side of the abdomen (left or 
right of navel). Additional site preparations and needle safety precautions are required. 
16. Remove the needle from the skin. Do not flush the winged infusion set.  Do not press or rub the site 
of injection. 
17. Immediately place the syringe and needle component into a disposal container.

STUDY INTERVENTION COMPLIANCE 
 
Not applicable. (All doses of the study medication will be administered at the Research Center.) 
 
6.5 
CONCOMITANT THERAPY 
 
For this protocol, a prescription medication is defined as a medication that can be prescribed only by a 
properly authorized/licensed clinician. Medications to be reported in the Case Report Form (CRF) are 
concomitant prescription medications, over-the-counter medications and supplements. 
 
As per the inclusion criteria, if the subject is receiving a cholinesterase inhibitor (donepezil, rivastigmine, 
or galantamine) and/or memantine, the dose must have been stable for at least 12 weeks before the 
screening visit, and the subject should remain on the same dose for the duration of the trial. As per the 
exclusion criteria, prohibited medications include any investigational product within 60 days or 5 half-
lives (whichever is longer) prior to the screening visit or anti-amyloid-beta or anti-tau protein 
monoclonal antibodies within one year prior to the screening visit, and for the duration of the trial. To

minimize the risk of injection site hematomas, anticoagulant medications, including warfarin, 
dabigatran, rivaroxaban, apixaban, edoxaban, heparin, or enoxaparin, are also prohibited throughout 
the treatment phase of the study (through Visit 17). Live/live-attenuated bacterial or viral vaccines are 
prohibited from 3 months prior to the screening visit and throughout the treatment phase of the study 
(through Visit 17). This includes oral typhoid, oral cholera, measles, mumps, rubella, oral polio (Sabin), 
yellow fever, varicella (Varivax or Zostavax), rotavirus, Japanese encephalitis, or live-attenuated 
influenza (FluMist) vaccines. Treatment with immunosuppressive medications, such as azathioprine, 
cyclosporine, methotrexate, tacrolimus, or mycophenylate, is prohibited from 2 months prior to the 
screening visit and throughout the treatment phase of the study (through Visit 17). Treatment with 
courses of corticosteroids longer than 5 days are prohibited from 2 months prior to the screening visit 
and throughout the treatment phase of the study (through Visit 17).  Due to potential interactions with 
rHuPH20 that could slow absorption of study medication, treatment with estrogens, or aspirin at a dose 
higher than 325 mg daily, is prohibited throughout the treatment phase of the study (through Visit 17). 
Medications that could have adverse effects on cognition, including opioid analgesics, centrally acting 
anticholinergic medications, sedative/hypnotic medications, and benzodiazepines, are not to be used 
within 72 hours prior to cognitive testing (at Screening, Visit 11, Visit 18, and Visit 19).

STUDY INTERVENTION AND PARTICIPANT DISCONTINUATION/WITHDRAWAL 
 
7.1 
DISCONTINUATION OF STUDY INTERVENTION 
 
Dose Delays and Dose Modifications: 
Individual dose modification of daratumumab is not permitted, but dose delay is recommended as the 
primary method for managing daratumumab-related toxicities.  
 
Daratumumab-Related Toxicity Management: 
If any of the following criteria are met and the toxicity is more than expected daratumumab injection 
must be held to allow for recovery from toxicity. If attribution is unclear, then daratumumab should be 
held until recovery from toxicity as noted below. 
 
The criteria for a dose delay are: 
• Grade 4 hematologic toxicity 
• Grade 3 thrombocytopenia with bleeding 
• Febrile neutropenia 
• Grade 3 or higher non-hematologic toxicities with the following exceptions: 
Grade 3 nausea that responds to antiemetic treatment within 7 days 
Grade 3 vomiting that responds to antiemetic treatment within 7 days 
Grade 3 diarrhea that responds to antidiarrheal treatment within 7 days 
Grade 3 fatigue that was present at baseline or that lasts for <7 days after the last 
administration of daratumumab

Grade 3 asthenia that was present at baseline or that lasts for <7 days after the last 
administration of daratumumab 
 
Administration of daratumumab may be restarted upon recovery from toxicity to Grade 2 or baseline, 
with the exception that Grade 2 laryngeal edema or Grade 2 bronchospasm must be fully recovered. If 
daratumumab administration does not commence within the prespecified window of the scheduled 
administration date (Table 3), then the dose will be considered a missed dose. Administration may 
resume at the next planned dosing date.

Interruption or discontinuation from daratumumab SC infusions does not mean discontinuation from 
the study, and subjects will be asked to return for scheduled assessments as per the protocol at Visit 11, 
Visit 18, and Visit 19, if not already completed.  If a clinically significant finding is identified (including, 
but not limited to changes from baseline) after enrollment, the investigator or qualified designee will 
determine if any change in participant management is needed. Any new clinically relevant finding will be 
reported as an adverse event (AE). 
 
7.2 
PARTICIPANT DISCONTINUATION/WITHDRAWAL FROM THE STUDY 
 
Participants are free to withdraw from participation in the study at any time upon request. 
An investigator may discontinue or withdraw a participant from the study for the following reasons: 
 
1. Significant study intervention non-compliance  
2. If any clinical adverse event (AE), laboratory abnormality, or other medical condition or situation 
occurs such that continued participation in the study would not be in the best interest of the 
participant 
3. If the participant meets an exclusion criterion (either newly developed or not previously recognized) 
that precludes further study participation 
 
The reason for participant discontinuation or withdrawal from the study will be recorded on the Case 
Report Form (CRF).  
 
7.3 
LOST TO FOLLOW-UP 
  
A participant will be considered lost to follow-up if he or she fails to return for 2 scheduled visits and is 
unable to be contacted by the study site staff.

The following actions must be taken if a participant fails to return to the clinic for a required study visit: 
1. The site will attempt to contact the participant and reschedule the missed visit if feasible and 
counsel the participant on the importance of maintaining the assigned visit schedule and ascertain if 
the participant wishes to and/or should continue in the study. 
2. Before a participant is deemed lost to follow-up, the investigator or designee will make every effort 
to regain contact with the participant (where possible, 3 telephone calls and, if necessary, a certified 
letter to the participant’s last known mailing address or local equivalent methods). These contact 
attempts should be documented in the participant’s medical record or study file.  
3. Should the participant continue to be unreachable, he or she will be considered to have withdrawn 
from the study with a primary reason of lost to follow-up.

STUDY ASSESSMENTS AND PROCEDURES 
 
8.1 
EFFICACY ASSESSMENTS  
  
Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog): The ADAS-Cog is the most widely 
used cognitive scale in AD clinical studies. The standard 11-item version (ADAS-Cog/11) includes both 
subject-completed tests and observer-based assessments. Specific tasks include Word Recall, Naming 
Objects and Fingers, Commands, Constructional Praxis, Ideational Praxis, Orientation, Word Recognition, 
and Language. The score ranges from 0 to 70 with each point representing a performance error and 
higher scores reflecting worse performance (Rosen et al. 1984). An improvement (decrease) of ≥ 4 
points in ADAS-cog/11 score has been deemed to be clinically meaningful (Raina et al. 2008). The 12-
item version (ADAS-Cog/12) adds a delayed word recall task, scored from 0 to 10. The ADAS-Cog/12 
score is the total of the ADAS-Cog/11 plus the delayed recall score, and therefore has a range of 0 to 80 
(Sano et al. 2011). The ADAS-Cog will be administered at the Screening Visit, Visit 11, Day 85+/-2, Visit 
18, Day 176+/-3, and Visit 19, Day 246+/-7. 
 
Clinical Dementia Rating Scale Sum of Boxes (CDR-SB): The CDR is a clinical global rating scale requiring 
the interviewing of both the subject and a study partner who knows and has contact with the subject. 
The CDR is a clinician-directed assessment of both cognition and function, and is intended to capture the 
state and therefore the disease stage of the individual (Hughes et al. 1982). The CDR-SB has been 
proposed as an acceptable approach for following disease progression and confirming treatment in AD 
(Lynch et al. 2006). The CDR assesses 6 domains of subject function: memory, orientation, judgment and 
problem solving, community affairs, home and hobbies and personal care. Each of these items has a 
maximum possible score of 3 points and the total score is a sum of the item scores (sum of boxes) giving 
a total possible score of 0 to 18, with higher scores indicating more impairment. The CDR will be 
administered at the Screening Visit, Visit 11, Day 85+/-2, Visit 18, Day 176+/-3, and Visit 19, Day 246+/-7. 
 
Mini Mental State Examination (MMSE): The MMSE is a 30-point scale that measures orientation to 
time and place, registration, immediate and delayed recall, attention, language, and drawing (Folstein et 
al. 1975). Scores range from 0 (most impaired) to 30 (no impairment). The MMSE will be administered at 
the Screening Visit, Visit 11, Day 85+/-2, Visit 18, Day 176+/-3, and Visit 19, Day 246+/-7.

AD Composite Score (ADCOMS): The ADCOMS is a composite score derived from a weighted 
combination of selected items from the ADAS-cog/12, MMSE, and CDR-SB. The range of the ADCOMS is 
between 0 and 1.97. A higher score is indicative of greater impairment. Items contributing to the 
ADCOMS include 4 items of the ADAS-cog, two items of the MMSE (scored in reverse, as item maximum 
score minus measured score), and all six items of the CDR-SB (Wang et al. 2016). 
 
8.2 
SAFETY AND OTHER ASSESSMENTS 
 
Demographics: Subject demographic information will be collected at the Screening Visit, including date 
of birth (or age), sex, race/ethnicity, native language, and highest education level. 
 
Medical history: Medical and surgical history, prior and concurrent medications including cholinesterase 
inhibitor and memantine use, and current medical conditions will be recorded at the Screening Visit. 
Medical history will include history of cognitive impairment and psychiatric history. 
 
Height and weight: Height will be measured at the Screening Visit. Weight will be measured at every 
visit except Visit 11 (the interim cognitive testing visit). 
 
Vital signs: Temperature, blood pressure, heart rate, and respiratory rate will be assessed at the 
Screening Visit, prior to every infusion, 1 hour and 2 hours after the first infusion (Visit 1), 1 hour after 
every subsequent infusion (Visits 2 through 10 and 12 through 17), and at Visits 11, 18, and 19. 
 
Physical and neurological examination: Physical and neurological examination will be performed by a 
study physician at the Screening Visit, Visit 11, Visit 18, and Visit 19. 
 
Modified Hachinski Ischemia Score (MHIS): The Rosen-Modified Hachinski Ischemia Score (MHIS) is a 
tool to identify the possibility of a vascular etiology for a subject’s cognitive impairment (Rosen et al. 
1980). It will be performed by a study physician at the Screening Visit. 
 
Geriatric Depression Scale (GDS): The Geriatric Depression Scale (GDS) (15 point version) is a 
screening assessment tool for depression specifically designed for older people (Sheikh and Yesavage 
1986). A score of 5 or higher is suggestive of depression. It will be performed at the Screening Visit. 
 
Electrocardiogram (ECG): 12-lead ECG will be obtained for screening purposes only at the Screening 
Visit. 
 
Blood tests: Blood tests to be collected at the Screening Visit will include complete blood count (CBC), 
comprehensive metabolic panel (CMP), prothrombin time (PT)/international normalized ratio (INR), 
activated partial thromboplastin time (APTT), thyroid-stimulating hormone (TSH), vitamin B12 level, 
hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C virus antibody 
(HCVAb), and human immunodeficiency virus antigen/antibody screen (HIVAg/Ab). Blood samples will 
be obtained at Visit 1, prior to the first infusion, for type and screen and flow cytometry. After the first 
dose, subjects will have a CBC performed within 48 hours prior to each subsequent infusion (Visits 2 
through 10 and 12 through 17). Additional safety laboratory monitoring will include a CMP every 4

weeks (Visits 4, 8, 10, 13, 15, and 17). CBC and CMP will also be obtained 12 weeks after the final dose 
(Visit 19). 
 
Brain MRI: Brain MRI will be performed within the screening period and at Visit 18. MRI acquisition will 
be performed on a 3T MRI scanner (Siemens MAGNETOM Prisma). The sequences obtained will include 
proton magnetic resonance spectroscopy (1H-MRS) from a mid-sagittal oblique 10.8 cm3 (2 × 2 × 2.7 cm) 
voxel in the region of the precuneus and posterior cingulate cortex. 
 
Amyloid PET scan of brain: An amyloid PET scan may be performed within the screening period to 
confirm deposition of amyloid in the brain. A historical amyloid positive PET scan may be used provided 
that the scan and result are considered acceptable by the investigator. 
 
Concomitant medications: Concomitant medications will be recorded at the Screening Visit and 
reviewed and updated at Visits 1-19. 
 
Adverse events review: Subjects and study partners will be asked about adverse events at Visits 1-19. 
Adverse events will also be assessed if they are reported at any other time during the study by the 
subject or study partner, in person or by telephone. 
   
8.3 
ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS 
 
8.3.1 DEFINITION OF ADVERSE EVENTS (AE) 
 
An adverse event is any untoward medical occurrence in a clinical study subject administered a 
medicinal (investigational or non-investigational) product. An adverse event does not necessarily have a 
causal relationship with the treatment. An adverse event can therefore be any unfavorable and 
unintended sign (including an abnormal finding), symptom, or disease temporally associated with the 
use of a medicinal (investigational or non- investigational) product, whether or not related to that 
medicinal (investigational or non-investigational) product. [Definition per International Conference on 
Harmonisation (ICH)] 
 
This includes any occurrence that is new in onset or aggravated in severity or frequency from the 
baseline condition, or abnormal results of diagnostic procedures, including laboratory test abnormalities 
 
8.3.2 DEFINITION OF SERIOUS ADVERSE EVENTS (SAE)  
 
A serious adverse event based on ICH and EU Guidelines on Pharmacovigilance for Medicinal Products 
for Human Use is any untoward medical occurrence that at any dose: 
 
• 
Results in death 
• 
Is life-threatening (The subject was at risk of death at the time of the event. It does not refer to 
an event that hypothetically might have caused death if it were more severe.)* 
• 
Requires inpatient hospitalization or prolongation of existing hospitalization 
• 
Results in persistent or significant disability/incapacity

25 
 
• 
Is a congenital anomaly/birth defect 
• 
Is a suspected transmission of any infectious agent via a medicinal product 
• 
Is medically important** 
 
*Life-Threatening Conditions:  
Disease progression should not be recorded as an adverse event or serious adverse event term; instead, 
signs and symptoms of clinical sequelae resulting from disease progression/lack of efficacy will be 
reported if they fulfill the serious adverse event definition. 
 
**Medical and scientific judgment should be exercised in deciding whether expedited reporting is also 
appropriate in other situations, such as important medical events that may not be immediately life 
threatening or result in death or hospitalization but may jeopardize the subject or may require 
intervention to prevent one of the other outcomes listed in the definition above. These should usually 
be considered serious. NOTE: DEATH FOR ANY REASON SHOULD BE REPORTED AS A SERIOUS ADVERSE 
EVENT. 
8.3.2.1 HOSPITALIZATION  
 
For reports of hospitalization, it is the sign, symptom or diagnosis which led to the hospitalization that is 
the serious event for which details must be provided. 
 
Any event requiring hospitalization or prolongation of hospitalization that occurs during the study must 
be reported as a serious adverse event, except hospitalizations for the following: 
 
• 
Hospitalizations not intended to treat an acute illness or adverse event (e.g., social reasons such 
as pending placement in long-term care facility) 
• 
Surgery or procedure planned before entry into the study. [Note: Hospitalizations that were 
planned before the start of data collection and where the underlying condition for which the 
hospitalization was planned has not worsened will not be considered serious adverse events. 
Any adverse event that results in a prolongation of the originally planned hospitalization is to be 
reported as a new serious adverse event.] 
 
 
 
8.3.3 CLASSIFICATION OF AN ADVERSE EVENT 
8.3.3.1 SEVERITY OF EVENT 
 
For adverse events (AEs) not included in the protocol defined grading system, the following guidelines 
will be used to describe severity.  
 
• 
Mild – Events require minimal or no treatment and do not interfere with the participant’s daily 
activities. [Equivalent to National Cancer Institute (NCI) Common Terminology Criteria for 
Adverse Events (CTCAE) Grade 1]

DARZAD Protocol – Version 1.1    25 APR 2019 
 
26 
 
• 
Moderate – Events result in a low level of inconvenience or concern with the therapeutic 
measures. Moderate events may cause some interference with functioning. [Equivalent to NCI 
CTCAE Grade 2] 
• 
Severe – Events interrupt a participant’s usual daily activity and may require systemic drug 
therapy or other treatment. Severe events are usually potentially life-threatening or 
incapacitating. [Equivalent to NCI CTCAE Grade 3 or higher] Of note, the term “severe” does not 
necessarily equate to “serious”. 
 
8.3.3.2 RELATIONSHIP TO STUDY INTERVENTION 
 
All adverse events (AEs) must have their relationship to study intervention assessed by the clinician who 
examines and evaluates the participant based on temporal relationship and his/her clinical judgment. 
The degree of certainty about causality will be graded using the categories below. In a clinical trial, the 
study product must always be suspect.  
 
• 
Related – The AE is known to occur with the study intervention, there is a reasonable possibility 
that the study intervention caused the AE, or there is a temporal relationship between the study 
intervention and event. Reasonable possibility means that there is evidence to suggest a causal 
relationship between the study intervention and the AE. 
• 
Not Related – There is not a reasonable possibility that the administration of the study 
intervention caused the event, there is no temporal relationship between the study intervention 
and event onset, or an alternate etiology has been established. 
 
8.3.3.3 EXPECTEDNESS  
 
The investigator will be responsible for determining whether an adverse event (AE) is expected or 
unexpected.  An AE will be considered unexpected if the nature, severity, or frequency of the event is 
not consistent with the risk information previously described for the study intervention. 
 
An adverse event is considered unlisted if the nature or severity is not consistent with the applicable 
product reference safety information. For a medicinal product(s) with a marketing authorization, the 
expectedness of an adverse event will be determined by whether or not it is listed in the applicable 
product information.  
 
http://www.darzalex.com/shared/product/darzalex/darzalex-prescribing-information.pdf 
 
For daratumumab, the expectedness of an adverse event will be determined by whether or not it is 
listed in the Investigator's Brochure. 
8.3.4 TIME PERIOD AND FREQUENCY FOR EVENT ASSESSMENT AND FOLLOW-UP 
 
The occurrence of an adverse event (AE) or serious adverse event (SAE) may come to the attention of 
study personnel during study visits and interviews of a study participant presenting for medical care, or 
upon review by a study monitor.

All AEs including local and systemic reactions not meeting the criteria for SAEs will be captured on the 
appropriate case report form (CRF). Information to be collected includes event description, time of 
onset, clinician’s assessment of severity, relationship to study product (assessed only by those with the 
training and authority to make a diagnosis), and time of resolution/stabilization of the event. All AEs 
occurring while on study must be documented appropriately regardless of relationship. All AEs will be 
followed to adequate resolution. 
 
Any medical condition that is present at the time that the participant is screened will be considered as 
baseline and not reported as an AE. However, if the study participant’s condition deteriorates at any 
time during the study, it will be recorded as an AE.  
 
Changes in the severity of an AE will be documented to allow an assessment of the duration of the event 
at each level of severity to be performed. AEs characterized as intermittent require documentation of 
onset and duration of each episode. 
 
The investigator or study coordinator will record all reportable events with start dates occurring any 
time after informed consent is obtained until 7 (for nonserious AEs) or 30 days (for SAEs) after the last 
day of study participation.  At each study visit, the study staff will inquire about the occurrence of 
AE/SAEs since the last visit.  Events will be followed for outcome information until resolution or 
stabilization. 
 
All serious adverse events that have not resolved by the end of the study, or that have not resolved 
upon discontinuation of the subject's participation in the study, must be followed until any of the 
following occurs: 
•  The event resolves 
•  The event stabilizes 
•  The event returns to baseline, if a baseline value/status is available 
•  The event can be attributed to agents other than the study drug or to factors unrelated to study  
conduct 
•  It becomes unlikely that any additional information can be obtained (subject or health care 
practitioner refusal to provide additional information, lost to follow-up after demonstration of due 
diligence with follow-up efforts) 
 
Maintenance of Safety Information: 
All safety data should be maintained in a clinical database in a retrievable format. The Principal 
Investigator shall provide all adverse events, both serious and non-serious, in report format. However, in 
certain circumstances more frequent provision of safety data may be necessary, e.g. to fulfill a 
regulatory request, and as such the data shall be made available within a reasonable timeframe at 
Janssen Scientific Affairs, LLC request. 
 
8.3.5 ADVERSE EVENT REPORTING  
 
All adverse events (AEs) will be recorded in the Case Report Form (CRF), and will be reviewed on an 
ongoing basis by the investigator and the Independent safety monitor.  The Principal Investigator shall

be solely responsible for complying, within the required timelines, with any safety reporting obligation 
to competent Health Authorities and the IRB, as defined in applicable laws and regulations.  For the 
purposes of this section, safety data includes adverse events, product quality complaints (PQCs), and 
special situations including pregnancies. The Principal Investigator will provide safety information to 
Janssen Scientific Affairs, LLC on adverse events, special situations including pregnancies and product 
quality complaints as defined within this section. This study has been designated as an interventional 
study.  As such, all adverse events for Janssen Medicinal Products regardless of causality and special 
situations excluding those from subjects not exposed to a Janssen Medicinal Product and product quality 
complaints with or without an adverse event as described in this Exhibit will be reported from the time a 
subject has signed and dated an Informed Consent Form (ICF) until completion of the subject’s last 
study-related procedure (which may include contact for follow-up safety).  Serious adverse events will 
be reported for 30 days after the last dose of study drug. For the purposes of this study, the Janssen 
medicinal product is daratumumab. Nonserious AEs will be reported to Janssen Scientific Affairs, LLC on 
an annual basis. Timetables for reporting serious adverse events, events of special interest, pregnancy, 
and product quality complaints are detailed in the relevant sections below. 
 
The Principal Investigator will transmit all SAEs, Adverse Events of Special Interest and special situations 
following exposure to a Janssen product under study in a form provided by Janssen Scientific Affairs, LLC

The study clinician will immediately report to Janssen Scientific Affairs, LLC any serious adverse event, 
whether or not considered study intervention related, including those listed in the protocol or 
Investigator’s Brochure and must include an assessment of whether there is a reasonable possibility that 
the study intervention caused the event.  
 
All serious adverse events (SAEs) will be followed until satisfactory resolution or until the investigator 
deems the event to be chronic or the participant is stable. Other supporting documentation of the event 
may be requested by Janssen Scientific Affairs, LLC and should be provided as soon as possible. 
 
The Institution/Principal Investigator will be responsible for notifying the Food and Drug Administration 
(FDA) of any unexpected fatal or life-threatening suspected adverse reaction as soon as possible, but in 
no case later than 7 calendar days after the Institution/Principal Investigator’s initial receipt of the 
information.  In addition, the Institution/Principal Investigator must notify the FDA in an Investigational 
New Drug (IND) safety report of potential serious risks, from clinical trials or any other source, as soon as 
possible, but in no case later than 15 calendar days after the Institution/Principal Investigator 
determines that the information qualifies for reporting. 
 
8.3.7 REPORTING EVENTS TO PARTICIPANTS  
   
Subjects and study partners will be informed of any clinically significant incidental findings on laboratory 
testing or imaging studies. With appropriate written authorization from the subject or their legally 
authorized representative, those results can be communicated to the subject’s treating physician(s). A 
summary of the aggregate results of the study will be provided to study participants after data analysis 
is complete, and will be posted on the ClinicalTrials.gov website. 
 
8.3.8 EVENTS OF SPECIAL INTEREST  
 
Adverse events of special interest are events that Janssen Scientific Affairs, LLC is actively monitoring as 
a result of a previously identified signal (even if nonserious). These adverse events are: 
 
• 
Infusion reactions: ≥ Grade 3 
• 
Infections: ≥ Grade 4  
• 
Cytopenias: ≥ Grade 4  
• 
Tumor lysis syndrome 
• 
Other malignancies 
•

•  Medication error involving a Janssen medicinal product (with or without patient exposure to the 
Janssen medicinal product, e.g., name confusion) 
•  Suspected transmission of any infectious agent via administration of a medicinal product 
•  Unexpected therapeutic or clinical benefit from use of a Janssen medicinal product 
 
These safety events may not meet the definition of an adverse event; however, from a Janssen Scientific 
Affairs, LLC perspective, they are treated in the same manner as adverse events. Special situations 
should be recorded on the Adverse Event page of the CRF. 
 
Any special situation that meets the criteria of a serious adverse event should be recorded on a Serious 
Adverse Event Report Form and be reported to Janssen Scientific Affairs, LLC within 24 hours of 
becoming aware of the event. 
 
8.3.9 REPORTING OF PREGNANCY  
 
All initial reports of pregnancy must be reported to Janssen Scientific Affairs, LLC by the Principal 
Investigator within 24 hours of becoming aware of the event using the Serious Adverse Event Form. 
Abnormal pregnancy outcomes (e.g. spontaneous abortion, fetal death, stillbirth, congenital anomaly, 
ectopic pregnancy) are considered serious adverse events and must be reported using the Serious 
Adverse Event Form.  
 
Any subject who becomes pregnant during the study must be promptly withdrawn from the study and 
discontinue further study treatment. 
 
Because the effect of the Janssen medicinal product on sperm is unknown, pregnancies in partners of 
male subjects exposed to a Janssen medicinal product will be reported by the Principal Investigator 
within 24 hours of their knowledge of the event using the Serious Adverse Event Form.  Depending on 
local legislation this may require prior consent of the partner. 
 
Follow-up information regarding the outcome of the pregnancy and any postnatal sequelae in the infant 
will be required. 
 
8.3.10 REPORTING OF PRODUCT QUALITY COMPLAINTS (PQC)

or distribution of the product, or delivery system.  Not all PQCs involve a subject.  Lot and batch 
numbers are of high significance and need to be collected whenever available. 
 
Examples of PQC include but are not limited to: 
 
• 
Functional Problem: e.g., altered delivery rate in a controlled release product 
• 
Physical Defect:  e.g. abnormal odor, broken or crushed tablets/capsules 
• 
Potential Dosing Device Malfunction: e.g., autoinjector button not working, needle detaching 
from syringe 
• 
Suspected Contamination 
• 
Suspected Counterfeit 
 
A PQC may have an impact on the safety and efficacy of the product. Timely, accurate, and complete 
reporting and analysis of PQC information from studies are crucial for the protection of patients, 
investigators, and Janssen Scientific Affairs, LLC, and are mandated by regulatory agencies worldwide. 
Janssen Scientific Affairs, LLC has established procedures in conformity with regulatory requirements 
worldwide to ensure appropriate reporting of PQC information. Lot and/or Batch #s shall be collected or 
any reports failure of expected pharmacological action (i.e., lack of effect). The product should be 
quarantined immediately and if possible, take a picture. 
 
All initial PQCs involving a Janssen medicinal product under study must be reported to Janssen Scientific 
Affairs, LLC by the Principal Investigator within 24 hours after being made aware of the event. The 
Janssen contact will provide additional information/form to be completed. 
 
If the defect for a Janssen medicinal product under study is combined with either a serious adverse 
event or nonserious adverse event, the Principal Investigator must report the PQC to Janssen Scientific 
Affairs, LLC according to the serious adverse event reporting timelines.  A sample of the suspected 
product should be maintained for further investigation if requested by Janssen Scientific Affairs, LLC.

physical, psychological, economic, or social harm) than was previously known or recognized. 
 
8.4.2  UNANTICIPATED PROBLEM REPORTING  
 
The investigator will report unanticipated problems (UPs) to the reviewing Institutional Review Board 
(IRB). The UP report will include the following information: 
 
• 
Protocol identifying information: protocol title and number, PI’s name, and the IRB project 
number; 
• 
A detailed description of the event, incident, experience, or outcome;  
• 
An explanation of the basis for determining that the event, incident, experience, or outcome 
represents an UP;  
• 
A description of any changes to the protocol or other corrective actions that have been taken or 
are proposed in response to the UP. 
 
To satisfy the requirement for prompt reporting, UPs will be reported using the following timeline:   
 
• 
UPs that are serious adverse events (SAEs) will be reported to the IRB and to the Independent 
Safety Monitor as soon as possible, but within 5 business days of the investigator becoming 
aware of the event.  
• 
Any other UP will be reported to the IRB and to the Independent Safety Monitor as soon as 
possible, but within 5 business days of the investigator becoming aware of the problem.  
• 
All UPs should be reported to appropriate institutional officials (as required by an institution’s 
written reporting procedures) and the Office of the Human Research Protections (OHRP). The 
OHRP Director ensures that all steps of this process are completed within 30 days of the IRB 
decision. For more serious actions, the OHRP Director will expedite reporting. All 
correspondence with any federal agency will be sent on behalf and with knowledge of the 
Institutional Official. 
 
8.4.3 REPORTING UNANTICIPATED PROBLEMS TO PARTICIPANTS  
 
Subjects, study partners, and legally authorized representatives will be informed of any UPs that might 
affect their willingness to continue participation in the study. If the UP requires modification of the 
informed consent form, active subjects will be re-consented.

SAMPLE SIZE DETERMINATION 
 
This is a pilot study, the purpose of which is explore whether there is a clinically meaningful efficacy 
signal for daratumumab in patients with mild to moderate Alzheimer's disease. The proposed sample 
size of 15 patients is based on feasibility and availability of resources, and not on a formal power 
calculation. 
 
The following table provides estimates of proportions and their associated 95% confidence intervals for 
a sample size of 15 subjects.

For a sample size of 15 subjects, if 7 patients respond, the lower limit of the exact 95% binomial 
confidence interval is 0.213, (i.e., we are 95% certain that the true proportion with a response is no 
lower than 0.213).  Based on previous results in patients with mild to moderate AD maintained on stable 
treatment with a cholinesterase inhibitor, the expected responder rate at 25 weeks (defined as 
improvement in ADAS-cog/11 score of ≥ 4 points) is 20% (0.20) (Rockwood et al. 2007). Therefore, if 7 or 
more of 15 subjects respond, we would consider further study of daratumumab warranted. 
 
9.3 
POPULATIONS FOR ANALYSES 
 
Data from all subjects who receive at least one dose of study medication will be included in all efficacy 
and safety analyses.

9.4 
STATISTICAL ANALYSES 
 
9.4.1 GENERAL APPROACH 
 
Descriptive statistics (mean and standard deviation, median, minimum, and maximum) for all outcome 
measures at each timepoint will be calculated. 
 
Plots of the data, (including spaghetti plots) will be used to visualize patterns in the data.  Additional 
post hoc exploratory analyses may be carried out. 
 
9.4.2 ANALYSIS OF THE PRIMARY EFFICACY ENDPOINT 
 
The 11-item Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog/11) has been a 
standard cognitive outcome measure in clinical trials for patients with mild to moderate AD. Total scores 
range from 0–70, with higher scores indicating greater cognitive impairment. The average expected 
worsening (increase) on this scale over 6 months in this population is in the range of 2 to 3 points. A 
clinically meaningful improvement (decrease) on this scale has been deemed to be 4 or more points. 
Based on previous results in patients with mild to moderate AD maintained on stable treatment with a 
cholinesterase inhibitor, the expected responder rate at 25 weeks (defined as improvement in ADAS-
cog/11 score of ≥ 4 points) is 20% (0.20) (Rockwood et al. 2007). 
 
A patient will be considered a responder if they improve by a minimum of 4 points on the ADAS-cog/11 
scale at 25 weeks compared to baseline. The proportion of patients who respond to daratumumab will 
be estimated, and the associated 95% exact binomial confidence interval will be calculated. 
 
9.4.3 ANALYSIS OF THE SECONDARY ENDPOINTS 
 
Secondary Efficacy Endpoints will consist of the proportion of subjects who are unchanged or improved 
from baseline to 25 weeks on ADAS-cog/12 score (standard 11 items plus delayed word recall), Mini 
Mental State Examination (MMSE) score, Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score, 
and AD Composite Score (ADCOMS).   
 
All analyses will be carried out separately for each secondary endpoint listed above. 
 
For each measure of cognitive response, a patient will be classified as stable or improved if the score at 
25 weeks is the same or better than at baseline.  The proportion of patients who are stable/improved, 
and the associated 95% exact binomial confidence interval will be calculated. 
 
9.4.4 SAFETY ANALYSES 
 
The proportion of patients with one or more treatment-emergent adverse events will be estimated, and 
the associated 95% exact binomial confidence interval will be calculated.

9.4.5 BASELINE DESCRIPTIVE STATISTICS 
 
Descriptive statistics (mean and standard deviation, median, minimum, and maximum for continuous 
factors; frequency and proportion for categorical factors) for demographic and clinical factors (including 
age, sex, years of education, and baseline MMSE score) will be calculated.

9.4.8 TABULATION OF INDIVIDUAL PARTICIPANT DATA 
 
Not applicable. 
 
9.4.9 TERTIARY/EXPLORATORY ANALYSES 
 
The pattern of cognitive response to daratumumab, as measured by ADAS-cog/11, ADAS-cog/12, MMSE, 
CDR-SB, and ADCOMS, will be examined over time at baseline (prior to the start of daratumumab 
treatment), 12 weeks (midpoint), 25 weeks (endpoint), and 36 weeks (12 weeks after completion of 
treatment). 
 
For each measure of cognitive response, repeated measures analysis of variance (RMANOVA) where 
time (baseline, 12 weeks, 25 weeks, 36 weeks) is the within subjects effect, and there is not between 
subjects effect, will be used to examine the changes in each outcome over time.   
 
CD38 expression in circulating CD8+ T-cells will be measured with flow cytometry at baseline and at 25 
weeks. The paired t-test will be used to examine whether there is a change at 25 weeks vs baseline. 
 
Cerebral metabolite ratios will be measured on single-voxel protein magnetic resonance spectroscopy 
from the precuneus and posterior cingulate region at baseline and at 25 weeks, including: 
 
•  N-acetylaspartate/creatine (NAA/Cr) 
•  myo-inositol/creatine (mI/Cr) 
•  choline/creatine (Cho/mI)

All analyses will be carried out separately for each metabolite ratio endpoint listed above. The paired t-
test will be used to examine whether there is a change at 25 weeks vs baseline for each factor listed 
above. 
 
If the usual assumptions of the proposed parametric models are not met, an appropriate transformation 
or a suitable non-parametric method will be used.   
 
10 SUPPORTING DOCUMENTATION AND OPERATIONAL CONSIDERATIONS 
 
10.1 REGULATORY, ETHICAL, AND STUDY OVERSIGHT CONSIDERATIONS 
 
10.1.1 INFORMED CONSENT PROCESS 
 
10.1.1.1 CONSENT/ASSENT AND OTHER INFORMATIONAL DOCUMENTS PROVIDED TO 
PARTICIPANTS 
 
Consent forms describing in detail the study intervention, study procedures, and risks are given to the 
the subject, their study partner, and the subject's legally authorized representative (if applicable), and 
written documentation of informed consent is required prior to starting any study-related procedure.   
 
The following consent materials are submitted with this protocol: 
 
- Subject Informed Consent Form 
- Study Partner Information and Consent Form 
 
10.1.1.2 CONSENT PROCEDURES AND DOCUMENTATION 
 
Informed consent is a process that is initiated prior to the individual’s agreeing to participate in the 
study and continues throughout the individual’s study participation. Potential participants will be 
provided with a copy of the informed consent document ahead of research participation. This will allow 
the subject and their legally authorized representative (if applicable) the necessary time to carefully 
review detailed information about the study procedures, risks, and benefits, and ask questions or 
express concerns prior to making a decision about whether to participate. Prior to the initiation of any 
screening or study-specific procedures, the investigator or his  representative will explain the nature of 
the study to the subject, their study partner, and the subject's legally authorized representative (if 
applicable), and answer all questions regarding this study. Participants will be informed that 
participation is voluntary and that they may withdraw from the study at any time, without prejudice. 
The rights and welfare of the participants will be protected by emphasizing to them that the quality of 
their medical care will not be adversely affected if they decline to participate in this study. Due to the 
inherent nature of the study population, with cognitive impairment due to Alzheimer’s disease, it is 
anticipated that many of these subjects will lack decisional capacity to provide informed consent. 
Accordingly, all potential subjects will be assessed for capacity to provide informed consent by one of 
the study physicians, who are either neurologists or geriatric psychiatrists with extensive experience in

assessing decisional capacity. If a subject is determined to lack capacity to provide informed consent, 
surrogate consent will need to be obtained from a legally authorized representative. In that instance, 
the subject will also need to provide written assent to participate in the study. Each informed consent 
will be reviewed, signed and dated by the subject or their legally authorized representative (if 
applicable), the person who administered the informed consent, and any other signatories according to 
local requirements. A separate informed consent will also be reviewed, signed, and dated by the 
subject's study partner prior to beginning any study related screening activities. A copy of each informed 
consent will be given to the subject and their study partner and each original will be placed in the 
subject's study chart. An entry must also be made in the subject's dated source documents to confirm 
that informed consent was obtained prior to any study-related procedures and that the subject and 
study partner received signed copies.  
10.1.2 STUDY DISCONTINUATION AND CLOSURE 
  
This study may be temporarily suspended or prematurely terminated if there is sufficient reasonable 
cause.  Written notification, documenting the reason for study suspension or termination, will be 
provided by the suspending or terminating party to study participants, investigator, funding agency, the 
Investigational New Drug (IND) sponsor, and regulatory authorities.  If the study is prematurely 
terminated or suspended, the Principal Investigator (PI) will promptly inform study participants, the 
Institutional Review Board (IRB), and Janssen Scientific Affairs, LLC, and will provide the reason(s) for the 
termination or suspension.  Study participants will be contacted, as applicable, and be informed of 
changes to study visit schedule. 
  
Circumstances that may warrant termination or suspension include, but are not limited to: 
 
Determination of unexpected, significant, or unacceptable risk to participants 
 
Demonstration of efficacy that would warrant stopping    
 
Insufficient compliance with protocol requirements 
 
Data that are not sufficiently complete and/or evaluable 
 
Determination that the primary endpoint has been met 
 
Determination of futility 
 
The study may resume once concerns about safety, protocol compliance, and data quality are 
addressed, and satisfy Janssen Scientific Affairs, LLC,  the IRB, and/or the Food and Drug Administration 
(FDA). 
 
10.1.3 CONFIDENTIALITY AND PRIVACY  
 
Participant confidentiality and privacy is strictly held in trust by the investigator, research staff, and the 
sponsor. This confidentiality is extended to cover testing of biological samples in addition to the clinical 
information relating to participants. Therefore, the study protocol, documentation, data, and all other 
information generated will be held in strict confidence. No information concerning the study or the data 
will be released to any unauthorized third party without prior written approval of subject or their legally 
authorized representative.

All research activities will be conducted in as private a setting as possible. 
 
The study monitor, other authorized representatives of the Institution, representatives of the 
Institutional Review Board (IRB), regulatory agencies, or the pharmaceutical company supplying study 
product may inspect all documents and records required to be maintained by the investigator, including 
but not limited to, medical records (office, clinic, or hospital) and pharmacy records for the participants 
in this study. The clinical study site will permit access to such records. 
 
The study participant’s contact information will be securely stored at the clinical site for internal use 
during the study. At the end of the study, all records will continue to be kept in a secure location for as 
long a period as dictated by the reviewing IRB, Institutional policies, or regulatory requirements. 
 
The study data entry and study management systems used by clinical site research staff will be secured 
and password protected. The Feinstein Institute for Medical Research will be used as a central location 
for data processing and management. Vanderbilt University, with collaboration from a consortium of 
institutional partners, has developed a software toolset and workflow methodology for electronic 
collection and management of research and clinical trial data. REDCap (Research Electronic Data 
Capture) data collection projects rely on a thorough study-specific data dictionary defined in an iterative 
self-documenting process by all members of the research team with planning assistance from the 
Biostatistics Unit of the Feinstein Institute for Medical Research. The interactive development and 
testing process results in a well-planned data collection strategy for individual studies.  REDCap servers 
are housed in a local data center at the Feinstein and all web-based information transmission is 
encrypted. REDCap was developed specifically around HIPAA-Security guidelines and is recommended to 
Northwell Health’s researchers by our Clinical Research Service, Research Compliance Office and 
Institutional Review Board. REDCap has been disseminated for use locally at other institutions and 
currently supports more than 2500 active institutional partners and other institutions in more than 100 
countries (www.projectredcap.org). De-identified research data may be stored on portable electronic 
devices (e.g. laptops, tablets, flash drives, etc.).  All such devices will be encrypted as per Northwell 
Health policy (www.projectredcap.org). 
 
Certificate of Confidentiality: 
To further protect the privacy of study participants, a Certificate of Confidentiality (CoC) will be issued 
by the National Institutes of Health (NIH).  This certificate protects identifiable research information 
from forced disclosure. It allows the investigator and others who have access to research records to 
refuse to disclose identifying information on research participation in any civil, criminal, administrative, 
legislative, or other proceeding, whether at the federal, state, or local level. By protecting researchers 
and institutions from being compelled to disclose information that would identify research participants, 
Certificates of Confidentiality help achieve the research objectives and promote participation in studies 
by helping assure confidentiality and privacy to participants. 
 
10.1.4 FUTURE USE OF STORED SPECIMENS AND DATA  
 
Data collected for this study will be analyzed and stored at the Feinstein Institute for Medical Research.

10.1.6 SAFETY OVERSIGHT 
 
Safety oversight will be under the direction of an Independent Safety Monitor (ISM), a physician with 
relevant expertise whose primary responsibility is to provide independent safety monitoring in a timely 
fashion. This is accomplished by review of adverse events, immediately after they occur or are reported, 
with follow-up through resolution. The ISM will be notified of SAEs by the study team within 24 hours of 
knowledge of the event.  The ISM will be notified of unexpected problems as soon as possible, but 
within 5 business days of knowledge of the event. The ISM will be notified within 15 business days of 
severe (NCI CTCAE Grade 3 or 4) nonserious AEs. The study team will report aggregate mild to moderate 
(NCI CTCAE Grade 1 or 2) nonserious AEs to the ISM at 4-month intervals. The ISM evaluates individual 
and cumulative participant data when making recommendations regarding the safe continuation of the 
study. The ISM will be independent from the study conduct and free of conflict of interest, or measures 
should be in place to minimize perceived conflict of interest. 
 
10.1.7 CLINICAL MONITORING 
 
Clinical site monitoring is conducted to ensure that the rights and well-being of trial participants are 
protected, that the reported trial data are accurate, complete, and verifiable, and that the conduct of 
the trial is in compliance with the currently approved protocol/amendment(s), with International 
Conference on Harmonisation Good Clinical Practice (ICH GCP), and with applicable regulatory 
requirement(s).  
 
The Clinical Monitor, or designee, will perform the following oversight and monitoring tasks in 
accordance with protocol specific requirements, Good Clinical Practice Guidelines, and Northwell Health 
Policy GR080, “Human Subject Research Oversight and Monitoring”.

consistency of the quality of results.  All calibration and quality assurance of laboratory testing 
equipment is routinely performed by the Northwell Core Laboratory.  
 
2. 
All medical equipment used in the care of research subjects, including but not limited to, blood 
pressure cuff, thermometer, electrocardiogram, pulse oximeter, etc. are routinely checked by 
Northwell Health’s bioengineering group and labeled with safety stickers at 6-month intervals. 
 
3. 
Disposable patient supplies; blood collection tubes, phlebotomy supplies, syringes, etc. are 
routinely checked for expiration dates on a monthly basis. 
 
4. 
Custom training plans will be created for nurses that will administer study medication.  
Documentation of successful completion of training will be required before study nurses will be 
authorized to administer study medication. 
 
5. 
Investigational pharmacy records will be reviewed biannually, or more often as needed, to 
include receipt of investigational drug, storage records, temperature logs, and dispensing logs. 
 
The Clinical Monitor will verify that the clinical trial is conducted and data are generated and biological 
specimens are collected, documented (recorded), and reported in compliance with the protocol, 
International Conference on Harmonisation Good Clinical Practice (ICH GCP), and applicable regulatory 
requirements [e.g., Good Laboratory Practices (GLP), Good Manufacturing Practices (GMP)].  
 
The investigational site will provide direct access to all source data/documents, and reports for the 
purposes of monitoring and inspection by local and regulatory authorities. 
 
 
10.1.9 DATA HANDLING AND RECORD KEEPING  
 
10.1.9.1 DATA COLLECTION AND MANAGEMENT RESPONSIBILITIES  
 
Data collection is the responsibility of the clinical trial staff at the site under the supervision of the site 
investigator. The investigator is responsible for ensuring the accuracy, completeness, legibility, and 
timeliness of the data reported. 
 
All source documents should be completed in a neat, legible manner to ensure accurate interpretation 
of data.   
 
Hardcopies of the study visit worksheets will be provided for use as source document worksheets for 
recording data for each participant enrolled in the study.  Data recorded in the electronic case report 
form (eCRF) derived from source documents should be consistent with the data recorded on the source 
documents.  
 
Clinical data (including adverse events (AEs), concomitant medications, and expected adverse reactions 
data) and clinical laboratory data will be entered into REDCap, a 21 CFR Part 11-compliant data capture

system provided by the Feinstein Institute for Medical Research. The data system includes password 
protection and internal quality checks, such as automatic range checks, to identify data that appear 
inconsistent, incomplete, or inaccurate. Clinical data will be entered directly from the source 
documents. 
 
10.1.9.2 STUDY RECORDS RETENTION  
 
Study documents should be retained for a minimum of 7 years after study close-out, a minimum of 2 
years after the last approval of a marketing application in an International Conference on Harminosation 
(ICH) region and until there are no pending or contemplated marketing applications in an ICH region, or 
until at least 2 years have elapsed since the formal discontinuation of clinical development of the study 
intervention, whichever is longer. No records will be destroyed without the written consent of Janssen 
Scientific Affairs, LLC.  
 
10.1.10 
PROTOCOL DEVIATIONS  
 
A protocol deviation is any noncompliance with the clinical trial protocol, International Conference on 
Harmonisation Good Clinical Practice (ICH GCP), or Manual of Procedures (MOP) requirements. The 
noncompliance may be either on the part of the participant, the investigator, or the study site staff. As a 
result of deviations, corrective actions are to be developed by the site and implemented promptly.  
 
These practices are consistent with ICH GCP:  
• 
4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3  
• 
5.1 Quality Assurance and Quality Control, section 5.1.1  
• 
5.20 Noncompliance, sections 5.20.1, and 5.20.2.  
It is the responsibility of the investigator to use continuous vigilance to identify and report protocol 
deviations. Major protocol deviations (those that affect subject safety, rights, welfare or data integrity) 
must be reported to the IRB within ten (10) working days of discovery. Minor protocol deviations (those 
that do not affect subject safety, rights, welfare or data integrity) may be reported to the IRB at 
continuing review, using a protocol deviation log. The investigator is responsible for knowing and 
adhering to the reviewing IRB requirements.  
 
10.1.11 
PUBLICATION AND DATA SHARING POLICY 
 
This study will comply with the Clinical Trials Registration and Results Information Submission rule. As 
such, this trial will be registered at ClinicalTrials.gov, and results information from this trial will be 
submitted to ClinicalTrials.gov. In addition, every attempt will be made to publish results in a peer-
reviewed journal.  Manuscripts and presentations will be reviewed by Janssen Scientific Affairs, LLC prior 
to submission to any journal or conference.
