8. Have viral sensitivity/susceptibility to at least one antiretroviral 
agent other than ibalizumab, as determined by a previous resistance 
test performed within 6 months of Screening, and be willing and 
able to be treated with at least one agent to which the patient’s viral 
isolate is fully sensitive/susceptible according to the Screening 
resistance tests as a component of the OBR 
9. If sexually active, are willing to use an effective method of 
contraception during the study and for 30 days after the last 
administration of the study drug 
Patient Population: 
Exclusion Criteria 
 
There are no Exclusion Criteria for patients meeting the Inclusion 
Criteria for Cohort 1. 
 
For Cohort 2, patients having or meeting any of the following 
conditions or characteristics will be excluded from the study: 
 
1. Eligible for participation in other TaiMed Biologics-sponsored 
clinical trials of ibalizumab 
2. Any significant diseases (other than HIV-1 infection) or clinically 
significant findings, including psychiatric and behavioral problems, 
determined from Screening, medical history, and/or physical 
examination that, in the investigator’s opinion, would preclude the 
patient from participating in the study 
3. Any significant acute illness within 1 week before the first 
administration of investigational medication on the study 
4. Any active infection secondary to HIV requiring acute therapy; 
however, patients who require maintenance therapy (i.e., secondary 
prophylaxis for opportunistic infections) will be eligible for the 
study. 
5. Any immunomodulating therapy (including interferon), systemic 
steroids, or systemic chemotherapy within 4 weeks before Day 0 
6. Any prior exposure to ibalizumab (formerly TNX-355 and Hu5A8) 
7. Any vaccination within 7 days before Day 0 
8. Any female patient who is pregnant, intends to become pregnant, or 
is currently breastfeeding 
9. Any current alcohol or illicit drug use that, in the investigator’s 
opinion, will interfere with the patient’s ability to comply with the 
study schedule and protocol evaluations 
10. Any previous clinically significant allergy or hypersensitivity to any 
excipient in the ibalizumab formulation 
11. Any radiation therapy during the 28 days before first administration

12. Any clinically significant Grade 3 or 4 laboratory abnormality 
according to the Division of AIDS (DAIDS) grading scale, except 
for the following asymptomatic Grade 3 events: 
➢ triglyceride elevation 
➢ total cholesterol elevation 
Study Design: 
 
This Phase 3, multicenter, expanded access study will evaluate the safety 
and tolerability of ibalizumab in treatment-experienced patients infected 
with MDR HIV-1. Patients will be enrolled in one of two Cohorts 
(Cohort 1 and Cohort 2): 
Cohort 1 (continuing treatment) 
◼ 
Patients will continue on an ibalizumab-containing regimen at 
their current dosage in combination with a current OBR.   
Cohort 2 (initiating ibalizumab) 
◼ 
On Day 0 patients will receive one 2,000 mg dose (loading dose) 
of ibalizumab. An OBR that is selected based on resistance test 
results and antiretroviral history will be initiated on Day 0 and 
must include at least one agent to which the patient’s virus is 
susceptible.  
◼ 
Beginning at Day 14, 800 mg of ibalizumab will be administered 
every 2 weeks through the remainder of the study. 
Virologic failure is defined as two consecutive measurements beginning 
at Week 24 or later if less than a 0.5 log10 decline in viral load from 
Baseline viral load. 
Patients may be discontinued from the study: 
▪ At the patient’s or investigator’s request 
▪ If the patient becomes pregnant 
▪ For protocol violation 
▪ For experiencing virologic failure 
▪ For treatment-related serious or intolerable adverse events (AEs) 
(DAIDS criteria, see Appendix B) 
▪ For toxicity (defined as two consecutive laboratory results, at 
least 14 days apart, with a CD4+ cell count below 200 cells/mm3 
that also represents a 50% reduction from the baseline CD4+ 
cell count) 
▪ Upon commercial availability of ibalizumab

Considerations: 
Sample Size: A sample size of approximately 100 patients is anticipated 
to be enrolled, though the number of participating patients will not be 
limited and may exceed 100. The analysis of study data will be primarily 
descriptive, with emphasis on tabular and graphical displays. Summary 
descriptive statistics will be calculated along with point and interval 
estimates of AEs. 
Effectiveness: (Cohort 2 only) The primary effectiveness endpoint of 
the study is the proportion of patients achieving a ≥0.5 log10 decrease 
from Baseline in viral load at Day 7. 
Safety Analyses: The safety analyses will include descriptions of 
treatment-emergent AEs (TEAEs), Class C events per the CDC 
Classification System for HIV Infection, clinical laboratory test results, 
physical examination findings, vital sign results, and immunogenicity of 
ibalizumab.

1. Introduction 
 
1.1 
Background 
Antiretroviral medications for treatment of human immunodeficiency virus (HIV) have evolved 
tremendously over recent years. Efficacy and tolerability have improved as well as the convenience 
of treatment regimens. The percentage of patients on treatment who maintain viral suppression 
approaches 75%-80%.1,2 Unfortunately, some patients harbor strains of HIV that are resistant to 
currently available therapies. Patients with multi-drug resistant (MDR) HIV have limited or no 
treatment options. Department of Health and Human Services (HHS) HIV treatment guidelines 
encourage these patients to seek clinical trials and expanded access programs.3   
 
TaiMed Biologics is currently developing ibalizumab for treatment of HIV. Ibalizumab is a 
monoclonal antibody that binds to a conformational epitope on domain 2 of the extracellular 
portion of the CD4 receptor. Ibalizumab binding reduces HIV replication by inhibiting viral entry 
into CD4+ T-cells. With this novel mechanism of action, ibalizumab has no known cross-resistance 
with other antiretroviral medications. Ibalizumab in combination with other antiretroviral 
medications has demonstrated safety and durable antiviral activity in clinical trials in HIV-1-infected, 
treatment-experienced patients with MDR HIV. Ibalizumab has been awarded Orphan Drug and 
Breakthrough Drug designations by the US Food and Drug Administration (FDA). Still, the clinical 
trial and regulatory approval process can take several years to complete; some patients who are in 
urgent need of treatment cannot wait for ibalizumab to secure approval. An expanded access to 
clinical trial is needed to provide potentially life-saving access for patients with MDR HIV and 
limited or no available treatment options.  
 
 
1.2 
Clinical Studies 
Prior studies have been conducted in HIV-positive individuals using the IV formulation of 
ibalizumab, and are summarized here. In addition, a study of ibalizumab administered 
subcutaneously (TMB-108) to HIV-negative at-risk volunteers has been completed. Another study 
(TMB-121) exploring both subcutaneous and intramuscular administration routes in both HIV-
negative and HIV-positive participants is ongoing.

Results from the Phase 1a clinical trial (Hu5A8.01) demonstrated that IV administration of a single 
dose of ibalizumab to HIV-infected patients was associated with dose-dependent mean viral load 
reductions of approximately 1 log10 in those receiving doses of 10 mg/kg or greater. Mean viral load 
reductions persisted for 2-3 weeks. In a subsequent Phase 1b study (TNX-355.02), ibalizumab was 
given to HIV-infected patients as a single agent (monotherapy) or added to failing highly active 
antiretroviral therapy (HAART). Multiple doses of ibalizumab again demonstrated clinically 
significant viral load reductions (median reductions approximately 1 log10) with viral load nadirs at 1-
2 weeks. A 24-week, double-blind, placebo-controlled, randomized, three-arm Phase 2a study 
(TNX-355.03) evaluated the safety, efficacy, and pharmacokinetics (PK) activity of two ibalizumab 
dose regimens (10 mg/kg and 15 mg/kg) in combination with an optimized background regimen 
(OBR) versus placebo with an OBR in treatment-experienced patients. As in the Phase 1 program, 
the Phase 2a study clearly demonstrated the antiviral activity of ibalizumab. Viral load reductions in 
the treatment arms were statistically significantly different from placebo, with approximately 1 log10 
reductions seen in the ibalizumab-containing arms at 24 weeks (primary endpoint) and 48 weeks. 
Also at 48 weeks, increases in CD4+ T-cell counts of approximately +50 cells/µL were observed for 
both of the active treatment arms versus virtually no change from baseline for the placebo arm (+1 
cell/µL). 
 
All single-dose and multiple-dose administrations of ibalizumab were generally well tolerated with 
no serious adverse events (SAEs) related to study drug, no dose-limiting toxicities related to study 
drug, and no evidence of adverse effects on the CD4+ T-cells of treated patients. When compared to 
placebo (Phase 2a) the incidences, spectrum, and intensity of AEs were similar between the active 
treatment arms and the placebo arm. While a statistically significant difference in incidence was not 
observed between either of the active treatment arms and the placebo arm, rash (mostly mild to 
moderate severity) did occur more often in active treatment arms than in the placebo arm. This 
observation appears to be consistent with the known association of rash with administration of 
humanized monoclonal antibody (MAb) medications.4 The administration of ibalizumab was not 
associated with immunosuppression, as evidenced by the lack of any increase in infections or 
malignancies in the study population treated with ibalizumab. Intradermal skin tests performed on a 
subset of patients were also similar between active treatment arms and placebo. Anti-ibalizumab 
antibodies have been detected transiently and at low titers in a small number of patients (2.4%). The 
observation of anti-ibalizumab antibody activity was not associated with any AEs and appeared to 
have no impact on antiviral efficacy. The significance of anti-ibalizumab antibodies is not known.

A Phase 2b clinical trial in 113 HIV-infected patients was also completed. Heavily treatment-
experienced patients enrolled in this study received IV doses of 800 mg of ibalizumab every 2 weeks 
(q2wk) or 2,000 mg every 4 weeks (q4wk) in combination with an OBR. The key primary efficacy 
endpoint was the proportion of patients with HIV-1 ribonucleic acid (RNA) levels below the assay 
limit (<50 copies/mL) at Week 24. The percentages of patients with <50 copies/mL at Week 24 
were 44% and 28% for the 800 mg q2wk arm and the 2,000 mg q4wk arm respectively, in the most 
stringent intention-to-treat (ITT) missing equals failure (MEF) analysis. Other noteworthy efficacy 
endpoints included mean change from Baseline in HIV-1 RNA at Week 24 and mean change in 
CD4+ T-cell counts. The mean change from Baseline at Week 24 was -1.6 log10 for the 800 mg q2wk 
arm and -1.5 log10 for the 2,000 mg q4wk arm. The mean change from Baseline in CD4+ T-cells at 
Week 24 was +37 cells/μL for the 800 mg q2wk group and +40 cells/μL for the 2,000 mg q4wk 
group. These results are consistent with quantitative measures of immune system recovery in a 
treatment-experienced population over 24 weeks in studies of other drugs. There was no statistically 
significant difference between the 800 mg q2wk and 2,000 mg q4wk arms in viral load outcomes at 
24 weeks. 
 
Similar to previous studies, ibalizumab in combination with the OBR was well tolerated in the Phase 
2b investigation. The incidences, spectrum, and intensity of AEs were similar across the two 
treatment arms. A total of 15 SAEs were reported in 14 randomized patients, and all SAEs were 
assessed as not related to study drug. The most frequent non-laboratory AEs were rash (13%), 
diarrhea (12%), and headache (9%); most did not result in discontinuation. Other clinical treatment-
emergent adverse events (TEAEs) that were reported in ≥ 5% of patients were nausea, 
nasopharyngitis, upper respiratory tract infection, cough, oral candidiasis, vomiting, and fatigue. 
Only rash and headache were considered treatment-related TEAEs in ≥ 5% of patients on study. 
One treatment-related TEAE (moderate rash) resulted in study discontinuation. Based on the overall 
study results, the 800 mg q2wk dose and the 2,000 mg q4wk dose demonstrated safety and efficacy 
in this treatment-experienced HIV-positive patient population. 
 
A subcutaneous formulation of ibalizumab has been developed and an initial Phase 1 clinical trial 
(TMB-108) conducted. TMB-108 was a randomized, placebo-controlled, double-blind, multi-dose 
sequential escalating dose study. The dosing cohorts were 120 mg, 240 mg, and 480 mg each given 
weekly. Each subject received weekly doses of ibalizumab subcutaneously for 4 weeks. Subjects who 
withdrew prior to completion of dosing for non-safety-related reasons were replaced.

No SAEs and no discontinuations due to AEs were reported on the protocol. No Grade 4 AEs 
were reported. One Grade 3 AE, “headache,” was reported. This AE was treated with over-the-
counter medications and resolved within one day of onset. Headache was also the most frequently 
reported AE, with all other reports of headache being mild to moderate in intensity. In addition to 
headache, AEs reported in more than one patient were cough, sinus/nasal congestion, and pruritis. 
No injection site reactions were reported. Taken together, the reported results of completed clinical 
studies suggest that ibalizumab is safe and has potent activity against HIV in humans. 
 
The phase 3 registrational study (TMB-301) was a single arm, multicenter study, conducted in 40 
treatment-experienced HIV-infected patients with multi-drug resistant HIV-1. Patients were treated 
with antiretrovirals for at least 6 months and were failing or had recently failed (i.e., in the last 8 
weeks) therapy to determine baseline viral load with documented HIV viral load of >1,000 
copies/mL.   
 
During Days 0 through 6, “the control period”, patients were monitored on current failing 
background regimen (or no therapy, if the patient had failed and discontinued treatment within the 8 
weeks preceding Screening). During Days 7 through 13, "the essential monotherapy period", 
patients continued on current failing therapy and received one 2000 mg dose (loading dose) of 
ibalizumab on Day 7. Day 7 was Baseline for the treatment period (Day 7-Week 25). On Day 14, 
viral load was assessed for the primary end point, thereafter the background regimen was optimized 
to include at least one agent to which the patient’s virus was susceptible. Beginning at Day 21, 800 
mg of ibalizumab was administered every 2 weeks through Week 23, the “maintenance period”. 
Thirty-one patients completed the Week 25/ End of Study Visit. The primary effectiveness endpoint 
was the proportion of patients achieving a ≥0.5 log10 decrease in viral load from Day 0 to Day 7 
and from Day 7 to Day 14. 
 
At Baseline, median viral load and CD4+ T cell counts were 4.55 log10 copies/mL (35,350 
copies/mL) and 73 cells/mm3, respectively. Baseline Overall Susceptibility Scores (OSS) was were 
0, 1, 2, or ≥2, for X (X13%), XX (X35%), XXX (X45%), and 3% of patients,  for 0, 1, and ≥2, 
respectively.  
 
In the ITT population, a statistically significant difference was observed between the proportion of 
patients achieving a  0.5 log10 decrease in viral load from Day 0 to Day 7 (Control period; 2.5%; 
95% CI: 0.0006, 0.1316) and compared with the proportion achieving a  0.5 log10 decrease from 
Day 7 to Day 14 after receiving a 2000 mg loading dose of ibalizumab (82.5%; 95% CI: 0.6722,

0.9266; p<0.0001). Sixty Fifty five percent of patients achieved ≥1.0 log10 reduction in viral load 
after receiving the 2000 mg loading dose, during the essential monotherapy period (Day 7 to Day 
14), and 55%after receiving the 2000 mg loading dose. maintained a ≥1.0 log10 reduction in viral 
load after receiving the and 800 mg q wk dose at once weekly through Week 25, during the 
maintenance period. during the essential monotherapy period (Day 7 to Day 14). The mean change 
in viral load from Baseline to Day 14 was  a 1.07 log 10  reduction and to Week 25 was a 1.64 log 10 
reduction at Day 14 was a 1.07 log10 reduction. 
 
An increase in the mean number of CD4+ T-cells of 63 cell/μL was observed from Baseline to 
Week 25.  This increase in CD4+ T-cells is indicative of the therapeutic effect over 24 weeks. 
At Week 25 after treatment with the 800 mg a 2wk maintenance dose, the mean change in viral load 
from Day 7 was 1.6 log10 reduction with 55% and 48% of patients having a ≥1 log10 and ≥2 log10 
reduction, respectively. Viral load <50 and <200 HIV-1 RNA copies/mL was reached in 43% and 
50% of patients, respectively.  
 
The most common adverse reactions (all Grades) reported in at least 5% of subjects were diarrhea, 
dizziness, nausea, and rash.  Table 1 shows the frequency of adverse reactions occurring in 5% or 
more of subjects.

As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody 
formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the 
observed incidence of antibody (including neutralizing antibody) positivity in an assay may be 
influenced by several factors including assay methodology, sample handling, timing of sample 
collection, concomitant medications, and underlying disease. For these reasons, comparison of the 
incidence of antibodies to ibalizumab in the studies described below with the incidence of antibodies 
in other studies or to other products may be misleading.  All subjects enrolled in clinical trial TMB-
301 and trial TMB-202 (a Phase 2b clinical trial that studied ibalizumab administered intravenously 
as 2,000 mg every 4 weeks or 800 mg every 2 weeks; the safety and effectiveness of this dosing 
regimen has not been established), were tested for the presence of anti-ibalizumab IgG antibodies 
throughout their participation. One sample tested positive with low titer anti-ibalizumab antibodies. 
No adverse reaction or reduced efficacy was attributed to the positive sample reported in this 
subject.

1.3 
Pharmacokinetic Profile 
IV administration of escalating single doses of ibalizumab (Protocol Hu5A8.01) demonstrated that 
serum concentrations of ibalizumab generally peaked at the end of the infusion period. Ibalizumab 
PKs were dose-dependent, as both systemic exposure and elimination half-life increased 
disproportionately with increasing dose. This indicated that the elimination of ibalizumab is capacity 
limited and saturable at higher doses. A similar conclusion was reached after a multiple-dose study 
of IV ibalizumab (Protocol TNX-355.02), which demonstrated that the steady state half-life 
following multiple doses of 10 and 25 mg/kg was 75 and 79 hours, respectively. The capacity-limited 
elimination is likely due to CD4 receptor turnover, given the short half-life for ibalizumab relative to 
endogenous IgG4 molecules. In the IV ibalizumab studies conducted to date, there was a correlation 
between ibalizumab trough serum concentrations of 0.3 µg/mL or higher and saturated binding of 
CD4 (receptor occupancy) on CD4+ T-cells, and between CD4 receptor occupancy and reductions 
in HIV viral load. Similar observations were made after subcutaneous administration of ibalizumab 
in HIV-negative volunteers, in which dose-dependent systemic exposure indicated saturable 
elimination with the same correlation between serum concentrations and CD4 receptor occupancy. 
A new study (TMB-121) of parenterally administered ibalizumab (subcutaneous and intramuscular) 
has been initiated to evaluate viral load responses in HIV-infected patients.

3. Study Plan 
 
3.1 
Overall Design 
This Phase 3, multicenter, expanded access study will evaluate the safety and tolerability of 
ibalizumab in treatment-experienced patients infected with MDR HIV-1. Eligible patients will 
include (1) those currently receiving ibalizumab under a TaiMed-sponsored or Investigator-
sponsored IND protocol and (2) treatment-experienced patients with no history of ibalizumab 
treatment who are on a failing regimen, or who have failed and are off treatment.   
 
Patients will be enrolled in one of two Cohorts (Cohort 1 and Cohort 2): 
 
Cohort 1 (continuing treatment) 
◼ 
Patients will continue on an ibalizumab containing regimen at their current dosage in 
combination with a current OBR.   
Cohort 2 (initiating ibalizumab) 
◼ 
On Day 0/Baseline, patients will receive one 2,000 mg dose (loading dose) of 
ibalizumab. The OBR will be initiated on Day 0/Baseline and must include at least one 
agent to which the patient’s virus is susceptible.  
◼ 
Beginning at Day 14, an 800 mg of ibalizumab will be administered every 2 weeks 
through the remainder of the study. 
Virologic failure is defined as two consecutive measurements at Week 24 or later if less than a 0.5 
log10 decline from the Baseline viral load (see Section 9.4 for the definition of Baseline). 
 
Patients will be discontinued from the study at the patient’s request or if the patient becomes 
pregnant, at investigator request, for protocol violation, for virologic failure, for treatment-related 
serious or intolerable AE(s) (Division of AIDS [DAIDS] criteria, see Appendix B), or for toxicity 
(defined as two consecutive laboratory results, at least 14 days apart, with a CD4+ cell count below 
200 cells/mm3 that also represents a 50% reduction from the Baseline CD4+ cell count).

3.2 
Discussion of Trial Design 
This study is designed to assess the safety and tolerability of IV ibalizumab. In addition, all patients 
will receive a standard of care OBR consisting of antiretroviral medications selected by the Principal 
Investigator based upon the patient's treatment history and the results of viral resistance testing. The 
effectiveness of the treatment regimen will also be assessed (Cohort 2 only). Safety and tolerability 
will be evaluated by the occurrence of AEs and discontinuations. The primary evaluation of 
effectiveness will be at Day 7. Additional secondary evaluations will be conducted at Day 7 and 
other assessment time points. 
 
This is an open-label safety study to provide early access to IV ibalizumab for HIV-1-infected 
patients who have no or limited treatment options on commercially available antiretroviral therapy 
(ART) and who are ineligible for participation in any other TaiMed Biologics-sponsored trial of 
ibalizumab. The safety and tolerability of IV ibalizumab in combination with an OBR in MDR HIV-
1-infected patients with limited or no treatment options will be assessed. Eligible patients already 
approved for Investigator-sponsored ibalizumab INDs (Cohort 1) will remain on Investigator-
sponsored INDs until they can be transitioned to this protocol. Upon enrollment, patients will 
continue to receive treatment with the previously assigned regimen: either ibalizumab 800 mg IV 
every 2 weeks with an OBR, or ibalizumab 2,000 mg IV every 4 weeks with an OBR. Treatment will 
continue until treatment-limiting toxicity, virologic failure, loss to follow-up, withdrawal from the 
trial, pregnancy, discontinuation of ibalizumab development, or commercial availability of 
ibalizumab. 
 
Eligible patients participating in TaiMed Protocol TMB-301 (who will enroll in Cohort 1 of this 
study) will continue to receive treatment with ibalizumab 800 mg IV every 2 weeks with an OBR 
while enrolled in this study. Treatment will continue until treatment-limiting toxicity, virologic 
failure, loss to follow-up, withdrawal from the trial, pregnancy, discontinuation of ibalizumab 
development, or commercial availability of ibalizumab. 
 
Eligible patients who are not participating in an Investigator-sponsored or TaiMed-sponsored 
ibalizumab IND (Cohort 2 of this study) will undergo a Screening period of, at most, 6 weeks. 
Patients will start treatment with ibalizumab 2,000 mg IV (loading) on Day 0 and then 800 mg IV 
(maintenance) on Day 14 and every 2 weeks thereafter. All patients will also receive an OBR 
beginning at Day 0. Treatment will continue until treatment-limiting toxicity, virologic failure, loss to

3.3 
Dose Selection 
Both dosages of IV ibalizumab (2,000 mg every 4 weeks and 800 mg every 2 weeks) were evaluated 
in the TMB-202 Phase 2b study. The results of that study indicated that higher serum concentrations 
and maximum receptor occupancy were achieved more rapidly with the 2,000 mg dose. Conversely, 
a higher percentage of patients on the 800 mg dose administered every 2 weeks achieved and 
maintained HIV RNA levels below 50 copies at Week 24 compared to patients on the 2,000 mg 
dose administered every 4 weeks. This observation may have been associated with the trend toward 
higher trough concentrations observed with the 800 mg dose. As the AE profile of both dosages 
was similar, the dosage regimen selected for Cohort 2 (patients initiating ibalizumab) in this study 
reflects the optimal PK features of each dose studied in TMB-202: A single 2,000 mg loading dose 
will be followed by 800 mg maintenance doses administered every 2 weeks. This dose regimen is 
designed to combine the maximal initial drug exposure of a 2,000 mg dosage with the more durable 
exposure of the 800 mg q2week dosage. Cohort 1 patients (continuing treatment) will continue on 
their current successful dosing regimens. 
 
 
3.4 
Schedule of Events 
The Schedule of Events is presented in Tables 3-1 and 3-2 for Cohort 1 patients receiving 
ibalizumab 800 mg every 2 weeks, in Tables 3-3 and 3-4 for Cohort 1 patients receiving ibalizumab 
2,000 mg every 4 weeks, and in Tables 3-5 and 3-6 for patients in Cohort 2. Throughout the study, 
patients are not required to fast before collection of blood samples for safety or effectiveness. 
However, patients should adhere to dietary recommendations as suggested for the components of 
their OBR or other concomitant medications.

1 Abbreviated physical examination includes examination of lymph nodes, respiratory and cardiovascular systems, abdomen, extremities, and nervous system. 
2  Patients need not fast before blood sampling. 
3  Viral resistance testing will include assessments of reverse transcriptase, protease, integrase, and envelope (entry) genes and chemokine coreceptor utilization; the samples will be 
collected and stored, and testing will only be performed for patients who experience virologic failure while on the study. 
4 Samples are to be drawn within 1 hour before the start of the infusion (if infusion is scheduled for that visit). 
5  All patients in Cohort 2 must be observed for 1 hour after the completion of study drug administration. If the patient does not experience an AE(s) related to the infusion (local or systemic) 
through and including the second infusion on Day 14, then the observation time can be reduced to 15 minutes thereafter. 
6 Patients who withdraw or are withdrawn at any time prior to the Week 102 visit should have Early Withdrawal procedures performed.

Effectiveness Assessments 
The primary effectiveness variable is the proportion of patients achieving a ≥0.5 log10 decrease from 
Baseline in viral load at Day 7 (assessed for Cohort 2 only). 
 
Secondary effectiveness variables will be the following: 
 
◼ 
Proportion of patients with HIV-1 RNA levels <50 copies/mL and <400 copies/mL at 
assessment time points (assessed for Cohort 2 only) 
◼ 
Mean change from Baseline in viral load at Day 7 and all assessment time points 
(assessed for Cohort 2 only) 
◼ 
Proportion of patients achieving a ≥0.5 log10 and ≥1.0 log10 decrease from Baseline in 
viral load at all assessment time points (assessed for Cohort 2 only) 
◼ 
HIV-1 sensitivity/susceptibility changes associated with virologic failure after 
administration of ibalizumab 
 
3.6 
Safety Assessments 
Safety assessments will include the results of the following measurements throughout the study: 
 
◼ 
Physical examinations 
◼ 
Vital sign measurements 
◼ 
Clinical laboratory parameters (hematology, serum chemistry, and urinalysis) 
◼ 
Monitoring of AEs and concomitant medications 
◼ 
Incidence of Class C events as defined by the Centers for Disease Control and 
Prevention (CDC) Classification System for HIV Infection (Appendix A) 
◼

4. Study Treatments 
 
4.1 
Study Drug Dosage and Administration 
There are two different ibalizumab IV drug product vial configurations available for use in this 
study:  
 
Current Drug Lots In Use 
(1) vials with a 1.33 mL injection volume and 200 mg ibalizumab per vial (Lots 201509019 and 
201505012).  
 
Patients receiving ibalizumab in study TMB-301, who will enroll into Cohort 1 of this study, and 
patients initiating ibalizumab in Cohort 2 will receive only vials with a 1.33 mL injection volume and 
200 mg ibalizumab per vial.  
 
Previous Drug Lot that is Depleted 
(2) vials with a 1.2 mL injection volume and 180 mg ibalizumab per vial (Lot 201403001.  This 
information is provided only in the event that Cohort 1 sites, with patients who were previously 
under Investigator sponsored IND protocols, may still have this lot in their inventory). 
 
All ibalizumab drug product to be used in this study will be at a concentration of 150 mg/mL. 
 
 
 
 
4.1.1 
Cohort 1 
Patients in Cohort 1 will continue receiving ibalizumab via IV infusion at the currently assigned 
dosage: either 800 mg q2wk or 2,000 mg q4wk.  
 
 
(Lots 201509019 and 201505012) 
For patients enrolling into this study from study TMB-301, study drug will be provided in open-
labeled cartons of 10 vials at 1.33 mL/200 mg each. For the 800 mg q2wk doses, 4 vials are to be

used. Using a sterile syringe, 1.33 mL is withdrawn from each of the vials to be used and injected 
into a 250 mL infusion bag of normal saline. Administration of the prepared infusion should begin 
no more than 6 hours after the time of preparation. 
 
(Lot 201403001) 
Until the supply of drug product currently allocated for use in Cohort 1 patients enrolling from 
Investigator-sponsored INDs is exhausted, study drugs for these patients will continue to be 
provided in open-labeled cartons containing 10 vials at 1.2 mL/180 mg each.  
• For the 2,000 mg q4wk doses (adjusted to 2,010 mg for this vial configuration), 13.4 mL 
total volume of ibalizumab drug product is required for each administration.  
• For the 800 mg q2wk doses (adjusted to 810 mg for this vial configuration), 5.4 mL total 
volume of ibalizumab drug product is required for each administration.  
Using a sterile syringe, the required content is withdrawn from each of the vials to be used and 
injected into a 250 mL infusion bag of normal saline. Administration of the prepared infusion 
should begin no more than 6 hours after the time of preparation. 
 
When the 1.2 mL, 180 mg/vial drug product is exhausted, patients enrolled in Cohort 1 from 
Investigator-sponsored INDs will be switched to the 1.33 mL, 200 mg/vial drug product. Study 
drug will then be provided in open-labeled cartons of 10 vials at 1.33 mL/200 mg each.  
• For the 2,000 mg q4wk doses, all 10 vials in a carton are to be used.  
• For the 800 mg q2wk doses, 4 vials are to be used.  
Using a sterile syringe, 1.33 mL is withdrawn from each of the vials to be used and injected into a 
250 mL infusion bag of normal saline. Administration of the prepared infusion should begin no 
more than 6 hours after the time of preparation. 
 
4.1.2 
Cohort 2 
(Lots 201509019 and 201505012) 
Study drug will be administered via IV infusion at a dose of 2,000 mg on one occasion (Day 
0/Baseline), followed 2 weeks later (Day 14) by doses of 800 mg administered once every 2 weeks

Using a sterile syringe, 1.33 mL is withdrawn from each of the vials to be used and injected into a 
250 mL infusion bag of normal saline. Administration of the prepared infusion should begin no 
more than 6 hours after the time of preparation. 
 
 
4.1.3 
Administration 
The infusion should be administered in the cephalic vein of the patient’s right or left arm. If this 
vein is not accessible, an appropriate vein located elsewhere can be used. For patients initiating 
ibalizumab in Cohort 2, the duration of the infusion should be no less than 30 minutes during the 
first two study drug administrations. If no infusion-associated AEs have occurred after two 
administrations, the duration of the infusion can be decreased to no less than 15 minutes.  
 
The start and stop times of each infusion will be recorded in an Electronic Data Capture (EDC) 
system, along with the site of administration. The date of use and the patient’s study identification 
(ID) number and initials will be recorded. 
 
All Cohort 2 patients must be observed for 1 hour after completion of study drug administration for 
at least the first two administrations (Day 0/Baseline and Day 14). If the patient does not experience 
an AE(s) related to the infusion (local or systemic) during the first two infusions, then the post-
infusion observation time can be reduced to 15 minutes thereafter. 
 
In addition to the study drug, all patients will receive an OBR, which is a standard-of-care regimen 
selected by the investigator based upon treatment history and the results of recent viral resistance 
testing. For patients enrolling into Cohort 2, previous resistance testing done within 6 months prior 
to Screening must demonstrate that the patient’s viral isolate is sensitive/susceptible to a minimum 
of one of the agents selected for the OBR. As part of the OBR, the patient must be willing and able 
to take at least one of the agents to which their virus is sensitive/susceptible. 
 
 
4.2 
Prohibited Medications and Restrictions 
Use of and changes in concomitant medications will be recorded in the patient’s source documents 
and the EDC system. All prescription drugs, herbal products, vitamins, minerals, and over-the-
counter medications are to be recorded.

Any concomitant medication, with the exception of those listed in Section 4.4.2 for Cohort 2 
patients, may be given at the discretion of the investigator. However, the investigator has the 
responsibility of ensuring that details regarding the concomitant medication are recorded for the 
patient in the EDC system. Complete information is expected for any medication prescribed during 
the trial. 
 
The prescribing information for all concomitant medications should be reviewed carefully. The 
guidance provided in the respective contraindications, warnings, and precautions section for any 
medication must be followed to prevent any potentially serious or life-threatening drug interactions. 
 
For patients enrolled into Cohort 2 only, the following medications are not to be administered 
concomitantly: 
 
◼ 
Therapeutic HIV vaccines from Screening until study participation ends 
◼ 
Any vaccines during the 7 days before Day 0/Baseline through Day 14 of the study 
◼ 
All investigational drugs from 30 days before Day 0/Baseline and throughout the study 
(except investigational antiretroviral medications as a component of the OBR) 
In addition, radiation therapy is not allowed for patients in Cohort 2 from 28 days before first 
administration of study drug to the last administration of study drug. Patients receiving radiation 
therapy are not allowed to enter Cohort 2 of the study; however, if a patient in Cohort 2 develops a 
condition that requires radiation but does not disqualify them from study participation for any other 
reason, then this event would need to be discussed with the medical monitor. 
 
First-dose, generalized, self-limiting skin rash has been described with therapeutic MAbs.5,6 Re-
challenge in such an event is at the discretion of the investigator. While there is no recommendation 
for premedication with diphenhydramine, acetaminophen, or corticosteroids, these medications have 
been used prior to the administration of other MAbs.7 Any patient who experiences anaphylactoid 
symptoms that are considered to be related to the study drug (possibly, probably, definitely) must 
have study drug discontinued and be withdrawn from the study immediately. Severe post-infusion 
reaction management typically includes corticosteroids, oxygen, and IV fluids, based on the severity 
and symptoms.7 Refer to Appendix C for further information on the management of suspected 
anaphylactoid reactions. Study drug should only be administered in a setting that allows for rapid

access to emergency cardiopulmonary support services in the event of a life-threatening infusion- 
related AE (e.g., anaphylaxis). 
 
 
4.3 
Measurement of Patient Adherence 
Patient adherence will require the availability of the patient at the study site to receive the dose and 
the patient’s willingness/ability to receive the entire dose. The receipt of the entire dose is assured, 
as each dose is given as an IV infusion by a trained professional from the clinical site and the event 
is recorded. Adherence to the OBR will also be recorded. 
 
 
4.4 
Missed Doses of Study Drug 
4.4.1 
Cohort 1 
Patients should receive study drug per the Schedule of Events (Section 3.4). A missed dose is 
defined as any dose of study drug that is not administered within the study visit window. Patients 
who miss doses of study medication for two consecutive dosing intervals (i.e., >28 days without a 
study drug infusion) of 800 mg dosage or one and one-half dosing intervals (i.e., >42 days without a 
study drug infusion) of the 2,000 mg dose may be withdrawn from the study.  
 
Missed Doses. If a dose is missed, the missed dose should be administered at the first opportunity. 
If an 800 mg dose is missed and cannot be administered at least 3 days before the next scheduled 
dose, it should be skipped. If a 2,000 mg dose is missed and cannot be administered at least 5 days 
before the next scheduled dose, it should be skipped.  
 
End of study (EOS) procedures should be performed as soon as possible after the patient qualifies 
for withdrawal due to missed doses. Patients who are withdrawn from the study for missed doses 
may not be permitted to participate in other ibalizumab protocols.

4.4.2 
Cohort 2 
Patients should receive study drug per the Schedule of Events (Section 3.4). A missed dose is 
defined as any dose of study drug that is not administered within the study visit window. Patients 
who miss doses of study medication for two consecutive dosing intervals (i.e., >28 days without a 
study drug infusion) or miss greater than two doses cumulatively will be withdrawn from the study. 
EOS procedures should be performed as soon as possible after the patient qualifies for withdrawal 
due to missed doses. Patients who are withdrawn from the study for missed doses may not be 
permitted to participate in other ibalizumab protocols. 
 
Missed Initial (Loading) Dose. If the initial 2,000 mg dose (loading dose) of study drug is 
administered outside the treatment window, the dose should be administered at the first available 
opportunity and the timing of subsequent doses should be adjusted to coincide with the actual 
administration time of the first dose. 
 
Missed Maintenance Dose (3-7 days). If a dose of 800 mg (maintenance dose) of study drug is 
missed by going beyond the scheduled dosing day by 3-7 days, a loading dose of 2,000 mg (reload) 
should be administered at the next available opportunity. The reload dose would substitute for the 
maintenance dose that was missed. All other visit procedures would not change other than the dose 
amount administered (i.e., 2,000 mg reload dose substituted for 800 mg maintenance dose). The 
scheduling of subsequent visits will not be adjusted. 
 
Example: If a patient is scheduled to receive study drug on Day 49 (Week 7) but cannot come in 
until Day 55, the patient should receive a 2,000 mg loading dose (reload) on Day 55. The subsequent 
dose should be 800 mg and scheduled for Day 63 (Week 9) (±2 day window). The patient should 
continue on the original visit schedule. 
 
Missed Maintenance Dose (>7 days and <14 days). If a dose of 800 mg (maintenance dose) of 
study drug is missed by going beyond the scheduled dosing day by more than 7 days but less than 14 
days, the patient should receive a 2,000 mg dose (reload) at the next available opportunity. The 
missed dose should be recorded as a missed dose/missed visit. A 2,000 mg reload dose administered 
between >7 days and <14 days beyond the scheduled dosing date will not substitute for the missed 
dose. The 2,000 mg reload dose will substitute for the next scheduled 800 mg maintenance dose. 
Study procedures for the visit subsequent to the missed dose/missed visit should be performed 
along with the administration of the 2,000 mg reload dose. The dosing schedule should be adjusted

such that the following 800 mg maintenance dose should be scheduled 2 weeks after the reload dose 
was administered. NOTE: Week 102/EOS procedures should be performed without regard to dose 
window whenever the visit occurs. 
 
Example: If a patient is scheduled to receive study drug on Day 49 (Week 7) but cannot come in 
until Day 58, the patient should receive a 2,000 mg loading dose (reload) on Day 58. Study 
procedures for Day 49 (Week 7) are recorded as missed. Study procedures for Day 63 (Week 9) are 
performed along with the administration of the 2,000 mg reload dose. The dose following the reload 
dose should be 800mg and scheduled for Day 72 (±2 day window). The visit schedule would be 
adjusted to 800 mg every 2 weeks from the day the drug was actually administered. 
 
No adjustments to dosage or dosing schedules are required for a missed dose that occurs before the 
dosing window. However, any dose administered before the dosing window is also considered a 
missed dose. 
 
 
4.5 
Study Drug Description 
The Sponsor or designee will provide the Research Pharmacists at the sites with vials containing 
study drug (active ibalizumab) manufactured under current Good Manufacturing Practices (cGMP). 
Ibalizumab is provided as a parenteral formulation in a 2 mL, clear-glass vial. The drug product 
contains ibalizumab at a concentration of 150 mg/mL, histidine United States Pharmacopoeia 
(USP), sucrose, sodium chloride, polysorbate 80, and water for injection USP at pH 6.0. Each vial 
contains either at least 1.2 mL of fluid delivering a total of 180 mg study drug per vial (Lot 
201403001) or at least 1.33 mL of fluid delivering a total of 200 mg study drug per vial (Lots 
201509019 and 201505012). Labeling will clearly identify the configuration of vials in each carton 
and of each individual vial. 
 
 
4.6 
Study Drug Packaging, Storage, and Disposal 
Study drug is provided as a single-use parenteral formulation in a 2 mL, clear-glass vial containing 
either at least 1.2 mL (Lot 204103001) or at least 1.33 mL (Lots 201509019 and 201505012) of drug 
product. The stability of the ibalizumab drug product at 2ºC to 8ºC is evaluated in ongoing studies. 
Study drug will be shipped under refrigerated conditions with a temperature-monitoring device.

Ibalizumab vials should be stored refrigerated at 2°C to 8°C (but NOT FROZEN) and protected 
from light. Investigator sites must store the investigational product in a secure location and maintain 
a temperature log of the storage conditions. 
 
The temperature must be continuously monitored with a continuous-monitoring temperature 
device. Temperature logs must be available for review at each site-monitoring visit. Temperature 
excursions outside the required limits should be reported promptly to the Sponsor, and the affected 
study drug should not be administered to any study patients until further instruction. The Sponsor 
or designee will investigate temperature excursions and adjudicate the disposition of any affected 
study drug. 
 
Any spent vials or remaining contents of used vials should be destroyed according to the site’s 
procedures for spent vial destruction and disposal, but only after complete drug accountability 
records have been reviewed and accepted during routine monitoring and after written permission 
has been given for spent vial destruction. The destruction should be recorded. 
 
 
4.7 
Study Drug Accountability 
The investigator will maintain accurate records of receipt of the entire supply of the study drug, 
including when, how much of, and conditions under which the study drug is received, dispensed, 
and destroyed by site personnel. In addition, the administration of study drug to each patient should 
be documented to the vial level for each infusion (i.e., lot number of every vial for that infusion, 
time of infusion bag preparation, time of administration, and documentation of full infusion 
received). Reasons for departure from the expected dispensing regimen must also be recorded. Drug 
accountability will be reviewed and documented at each study visit. Reconciliation and accountability 
of study drug will be done throughout the study during the monitoring visits. After the completion 
of the study, the Sponsor or designee may authorize the site to dispose of unused supplies of the 
investigational drug, provided this alternative disposition does not expose humans to risks from the 
drug. The Sponsor or designee shall maintain written records of all drug dispositions, which will 
include the name of the investigator; the date, quantity, batch, or code of each such shipment; and 
method of disposal.

5.3 
Patient Withdrawal and Discontinuation 
5.3.1 
Reasons for Withdrawal 
A patient may be withdrawn from the study if the patient: 
 
◼ 
Withdraws consent to participate or requests an early discontinuation at any time during 
the study 
◼ 
Is in violation of the protocol 
◼ 
Becomes pregnant during the study (see Section 8.7 for a description of procedures to 
be followed in case of pregnancy) 
◼ 
Experiences virologic failure 
◼ 
Experiences a treatment-related serious or intolerable AE(s) (according to DAIDS 
criteria, see Appendix B) 
◼ 
Experiences toxicity, defined as two consecutive laboratory results, at least 14 days 
apart, with a CD4+ cell count below 200 cells/mm3 that also represents a 50% reduction 
from the baseline CD4+ cell count 
The study treatment should be discontinued for all Grade 3 or 4 treatment-related abnormalities, as 
defined in Appendix B. Treatment-emergent Grade 3 or Grade 4 lab abnormalities should be 
retested within 72 hours. Any patient with a Grade 3 or Grade 4 lab abnormality that resolves before 
the next scheduled dose may have the study drug reinstituted. If a patient develops a persistent 
Grade 3 or Grade 4 treatment-emergent laboratory abnormality, excluding triglycerides and 
cholesterol, that does not resolve prior to the next scheduled study drug administration, study drug 
may be discontinued. 
 
A patient experiencing one or more treatment-emergent SAEs will receive treatment and follow-up 
evaluations by the Principal Investigator, or they will be referred to another appropriate physician 
for treatment and follow-up. Withdrawal from the study will be at the discretion of the Principal 
Investigator/Sponsor. 
 
The investigator will also withdraw a patient if the Sponsor or local regulatory agency (e.g., FDA) 
terminates the study. Upon occurrence of an SAE, the Principal Investigator will notify the Sponsor 
or designee of these events via the SAE hotline. If a patient is discontinued because of an AE, the

event will be followed until satisfactory resolution or until the Principal Investigator deems the event 
to be chronic or the patient to be stable. 
 
 
5.3.2 
Handling Withdrawals and Discontinuations 
Patients are free to withdraw from the study at any time upon request. Patient participation in the 
trial may be stopped at any time at the discretion of the investigator or at the request of the Sponsor 
or designee. At the time of withdrawal or discontinuation, the investigator will assess the best 
options for treatment and discuss these options with the patient. 
 
When a patient withdraws or is discontinued from the study, the reason(s) for withdrawal or 
discontinuation will be recorded by the investigator. Whenever possible, all patients who withdraw, 
or are discontinued from the study prematurely, will undergo all Early Withdrawal procedures as 
described in the Schedule of Events in Section 3.4. Patients who fail to return for final assessments 
will be contacted by the site personnel in an attempt to have the patients comply with the protocol. 
A minimum of two documented phone calls should be made over the course of at least 2 weeks. If 
the site personnel receive no response, they should send a certified letter requesting that the patient 
contact the site regarding their status in the study. If the patient does not respond at this point, the 
date the certified letter was mailed will be considered the date of study withdrawal. 
 
In the event of a patient death during the study, the date of death (as listed on the death certificate) 
will be used for the date of study discontinuation. 
 
It is vital to obtain follow-up data on any patient withdrawn because of an AE or SAE. In such 
cases, the patient will be followed to satisfactory resolution or until the Principal Investigator deems 
the event to be chronic or the patient to be stable. In any case, every effort must be made to 
undertake protocol-specified safety follow-up procedures. 
 
 
5.3.3 
Sponsor or Regulatory Agency Termination of Study 
Although the Sponsor intends to complete the study, the right is reserved to discontinue the study at 
any time for clinical or administrative reasons, upon commercial availability of ibalizumab, or if

required by the local regulatory authority (e.g., FDA). If the Sponsor discontinues the study, the 
FDA will be notified promptly. 
 
 
6. Study Visits 
 
6.1 
Cohort 1: 800 mg Every 2 Weeks 
Since there are no laboratory parameters required for entry into Cohort 1 of this study, Screening 
procedures and Day 0 procedures are scheduled for the same day. Patients who qualify for entry into 
Cohort 1 of this study who are currently receiving 800 mg ibalizumab every 2 weeks will have 
physical and laboratory measures performed and receive the first on-study dose of ibalizumab at 
Screening/Day 0 as specified in the Schedule of Events (see Table 3-1). These patients will return to 
the clinic on Day 14 and every 2 weeks thereafter through the remainder of participation in the 
study for study drug administration (800 mg) and effectiveness and safety evaluations. Patients who 
are discontinued or who withdraw from the study prematurely will be asked to return for an Early 
Withdrawal visit to have all assessments detailed in the Schedule of Events for that visit performed. 
 
 
6.1.1 
Screening/Day 0 
Screening and Day 0 (first on-study administration of ibalizumab) are scheduled for the same day. At 
this visit, study information will be reviewed and discussed, and the informed consent form will be 
reviewed and signed by the participant. No procedures, other than a preliminary verbal assessment 
of eligibility by review of inclusion/exclusion criteria, may be done before the informed consent 
process is complete. Once informed consent has been obtained and documented, the following 
procedures may be completed (pre-infusion): 
 
◼ 
Record demographics, medical history (general and HIV), and the patient’s height 
◼ 
Record all prior ART exposure; record all other medications taken within the last 30 
days 
◼ 
Record results of a complete physical examination 
◼ 
Record vital sign measurements

7. Study Assessments 
 
A central laboratory will analyze all blood and urine samples with the exception of the HIV-1 
resistance testing and immunogenicity testing, which will be undertaken by appropriate specialty 
contract laboratories. Urine samples will be analyzed at the site; if abnormal results are obtained for 
a patient, a urine sample will be sent to the central laboratory for microscopic evaluation. 
 
The following assessments will be conducted at the times indicated in the Schedule of Events 
(Tables 3-1 through 3-6). 
 
 
7.1 
Activities to Be Completed 
7.1.1 
Demographic Data, Medical History, and Concomitant Medications 
Demographic data, a complete medical history (per patient report), and documentation of prior 
medications will be collected at Screening; information about recent or concomitant medications will 
be obtained at each visit. If the patient is enrolling into Cohort 2, the patient will supply official 
written documentation of HIV-1 infection at Screening, if possible. Otherwise, a sample for an 
HIV-1 antibody test must be collected as part of the Screening procedures. 
 
 
7.1.2 
Complete Physical Examination 
A complete physical examination will include the following organ or body system assessments: head, 
eyes, ears, nose, throat, musculoskeletal, cardiovascular, lymphatic, respiratory, gastrointestinal, skin, 
neurological, and other findings of note. Height and weight will be measured at Screening, and 
weight only will be measured at other times specified.

7.1.3 
Abbreviated Physical Examination 
An abbreviated physical examination will be limited to lymph nodes, respiratory and cardiovascular 
systems, abdomen, extremities, and nervous system and assessment of any specific signs and 
symptoms that the patient reports. 
 
 
7.1.4 
Vital Sign Measurements 
Vital sign measurements will include the patient’s heart rate (beats/minute taken for 1 full minute), 
blood pressure (mm Hg), respiratory rate (breaths/minute taken for 1 full minute), and oral 
temperature (ºC). Measurements will be taken within 1 hour before the start of the infusion and 15 
minutes after the end of the infusion. Blood pressure and heart rate measurements will be obtained 
after the patient has been seated for at least 5 minutes. Ideally, each patient’s blood pressure should 
be measured using the same arm and the same size cuff at each visit. 
 
 
7.2 
Blood and Urine Samples 
7.2.1 
Hepatitis Serology and C-Reactive Protein 
Patients will be screened for hepatitis B (surface antigen) and hepatitis C to determine their hepatitis 
status. 
 
Blood samples will be taken for the analysis of C-reactive protein, which is an inflammatory marker 
whose concentration increases with acute or chronic inflammation. 
 
 
7.2.2 
Clinical Laboratory Parameters 
Collection of blood and urine samples for clinical laboratory assessments will be part of a normal 
safety profile assessment for the study patients. Patients need not fast before blood sampling. 
Samples will be processed using standard procedures as described in the laboratory procedures 
manual and will be analyzed by a central laboratory unless otherwise noted.

The samples will be analyzed for the following: 
 
◼ 
Hematology: complete white blood cell count with differential, hemoglobin, 
hematocrit, and platelets 
◼ 
Serum chemistry profile: albumin, alkaline phosphatase, alanine aminotransferase 
(ALT), amylase, aspartate aminotransferase (AST), blood urea nitrogen, calcium, 
chloride, creatine phosphokinase, creatinine, direct bilirubin, gamma glutamyl 
transferase, glucose, lactate dehydrogenase, lipase, lipid profile (total cholesterol, high-
density lipoprotein, low-density lipoprotein, and triglycerides), magnesium, phosphorus, 
potassium, sodium, total bilirubin, total protein, and uric acid 
◼ 
Urinalysis: visual inspection for appearance and dipstick assessment for color, pH, 
specific gravity, ketones, protein, glucose, bilirubin, nitrite, urobilinogen, and leukocyte 
esterase 
The urinalysis will be performed at the site by qualified personnel. If the results of the urinalysis are 
abnormal, a urine sample will be sent to the central laboratory for microscopic evaluation. Samples 
will be processed as described in the laboratory procedures manual before being sent to the central 
laboratory for evaluation. 
 
Tests with Grade 3 or Grade 4 abnormal results should be repeated within 72 hours of the site 
becoming aware of the abnormal value(s). See Appendix B for details and definitions of toxicities. 
The Principal Investigator should discuss any Grade 3 or 4 abnormal laboratory results with the 
medical monitor/Sponsor for appropriate patient disposition, including potential withdrawal from 
the study (see Section 5.3.1 for additional information). Per Section 5.3.1, the study treatment should 
be stopped for all Grade 3 or 4 treatment-related laboratory abnormalities, as defined in Appendix 
B. Any patient with a Grade 3 or Grade 4 laboratory abnormality that resolves before the next 
scheduled dose may have the study drug reinstituted. If a patient develops a persistent Grade 3 or 
Grade 4 treatment-emergent laboratory abnormality, excluding triglycerides and cholesterol, that 
does not resolve prior to the next scheduled study drug administration, study drug may be 
discontinued. Patients with Grade 3 or 4 triglyceride and/or cholesterol elevations are allowed to 
continue to receive study drug. 
 
 
7.2.3 
Archive Sample 
A separate blood sample will be taken and stored for possible research use.

7.2.4 
Serum Follicle-Stimulating Hormone Testing 
A serum FSH test will be performed on postmenopausal females at Screening (see Section 8.7). The 
level of FSH should exceed 35 IU/L for the patient to be considered postmenopausal. If the patient 
does not meet this criterion, she must agree to use proper birth control precautions as described in 
Section 8.7 and must have serum and urine pregnancy tests throughout the protocol at times 
specified in the Schedule of Events. 
 
 
7.2.5 
Pregnancy Testing 
A serum pregnancy test will be performed at Screening, EOS, Early Withdrawal and other defined 
visits for all females of childbearing potential. A urine pregnancy test will be performed at other 
defined study visits to confirm that a female has not become pregnant during the study. These tests 
are performed for the protection and safety of the fetus, as the risk to the fetus is unknown. Any 
patient who becomes pregnant during the study will be withdrawn from the study. See Section 8.7 
for a description of procedures to be followed in case of pregnancy. 
 
 
7.2.6 
HIV-1 RNA Level 
Blood samples for viral load will be used to determine the effectiveness of the study regimens and 
should be drawn before infusion during visits that include an infusion. 
 
 
7.2.7 
HIV-1 Viral Resistance Testing 
Blood samples for HIV-1 viral resistance testing should be collected before the start of the infusion 
at the indicated visits. Viral resistance testing will include assessments of reverse transcriptase, 
protease, integrase and envelope genes, and chemokine coreceptor utilization; the samples will be 
collected and stored, and testing will only be performed for patients who experience virologic failure 
while on the study.

Collected and stored samples may also be used for the TrofileTM Assay, a blood test that identifies 
the tropism of a patient’s HIV strain (i.e., R5, X4, or a combination). The results show whether the 
patient is infected with the virus that enters cells using the R5 co-receptor, the X4 co-receptor, or 
both. 
 
 
7.2.8 
CD4+ Cell Count 
Blood samples for CD4+ cell count will be collected over the course of the study to determine how 
well the immune system is functioning. In most patients infected with HIV, an increase in the 
number of CD4+ cells is an indicator of the effectiveness of antiretroviral medication. 
 
If a patient experiences toxicity, defined as two consecutive laboratory results, at least 14 days apart, 
with a CD4+ cell count below 200 cells/mm3 that also represents a 50% reduction from the baseline 
CD4+ cell count, the patient will be discontinued from the study. 
 
 
7.2.9 
Immunogenicity of Ibalizumab 
Blood samples will be collected to test for the development of antibodies against ibalizumab at Day 
0, EOS, Early Withdrawal, and other defined visits. Samples will be collected prior to ibalizumab 
infusion if an infusion is scheduled for that visit. The incidence of anti-ibalizumab antibody 
production will be determined using a validated enzyme-linked immunosorbent assay (ELISA) that 
has been validated for the detection of anti-ibalizumab antibodies in human serum even if circulating 
drug is present. Additional samples may be collected when clinical observations suggest the 
possibility of a clinically significant anti-ibalizumab immune response (e.g., allergic response, serum 
sickness, low drug levels, and/or loss of virologic response). 
 
 
8. Adverse Events 
 
8.1 
Definitions 
Per the FDA regulations in 21 CFR 312.32, the following definitions apply to this protocol:

DATE: 11 DECEMBER 2017 
 
 
Use or disclosure of data contained on this page is subject

79 
 
 
 
 
Adverse Events. An AE is defined as any untoward medical occurrence associated with the use of a 
drug in humans, whether or not considered drug related. 
 
Adverse Reaction. Any AE caused by a drug. 
 
Treatment-Emergent AEs. A TEAE is defined as any event not present before exposure to study 
drug or any event already present that worsens in either intensity or frequency following exposure to 
test medication. 
 
Serious Adverse Event or Serious Suspected Adverse Reaction. An AE or suspected adverse 
reaction is considered ‘‘serious’’ if, in the view of either the investigator or Sponsor, it results in any 
of the following outcomes: death, a life-threatening AE, inpatient hospitalization or prolongation of 
existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to 
conduct normal life functions, or a congenital anomaly/birth defect. Important medical events that 
may not result in death, be life-threatening, or require hospitalization may be considered serious 
when, based upon appropriate medical judgment, they may jeopardize the patient or subject and may 
require medical or surgical intervention to prevent one of the outcomes listed in this definition. 
 
Suspected Adverse Reaction. A suspected adverse reaction means any AE for which there is a 
reasonable possibility that the drug caused the AE. For the purposes of IND safety reporting, 
“reasonable possibility” means there is evidence to suggest a causal relationship between the drug 
and the AE. 
 
Unexpected Adverse Event or Unexpected Adverse Reaction. This term refers to an AE or 
adverse reaction that is not listed in the investigator’s brochure or is not listed at the specificity or 
severity that has been observed. 
 
 
8.2 
Eliciting Adverse Event Information 
At every study visit, patients will be asked a standard, nondirective question, such as “How have you 
been feeling since your last visit?” to elicit any medically related changes in their well-being. They 
will also be asked if they have been hospitalized, had any accidents, used any new medications, or 
changed concomitant medication regimens (both prescription and over-the-counter medications).

80 
 
 
 
 
In addition to patient self-report, AEs will be documented from clinically significant findings 
resulting from abnormal laboratory test values, physical examination findings, or other documents 
that are relevant to patient safety.  
 
 
8.3 
Reporting Adverse Events 
The investigator is responsible for reporting to the Sponsor or designee all AEs that are observed or 
reported by the patient during the study (from the time the patient signs informed consent until 30 
days after the last dose of study medication is given), regardless of their relationship to study drug or 
their clinical significance. Patients will be instructed to contact study site personnel at any time after 
informed consent if any symptoms develop. 
 
To ensure compliance with FDA regulations (21 CR 312.64), site investigators must immediately 
report to the Sponsor all AEs that meet the SAE criteria, regardless of presumed relationship to the 
investigational agent. The Sponsor will carefully review the SAE information to monitor the 
investigational drug’s toxicity profile and patient safety. If any event meets the FDA’s reporting 
criteria, it will be submitted to the FDA as an IND Safety Report (21 CFR 312.32). 
 
Recording of AEs will begin after study drug is first administered. Any untoward medical condition 
that occurs after the informed consent is signed but before the first administration of the study drug 
will be recorded as medical history, unless it is related to a study procedure. AEs will be recorded 
from the first dose of study medication and until 30 days after the last dose of study medication, 
regardless of its relationship to study drug. AEs will be documented in the patient’s source 
documents and recorded in the AE section of the EDC system. 
 
All AEs reported or observed during the study must be recorded in detail in the AE section of the 
EDC system and followed to a satisfactory resolution or until the Principal Investigator deems the 
event to be chronic or the patient to be stable. 
 
Information to be collected includes the event term, date of onset, date of resolution, Investigator-
specified assessment of severity and relationship to study drug, and seriousness, as well as any 
required treatment or evaluations and outcome.

Pre-existing conditions (present before the start of the AE collection period) are considered 
concurrent medical conditions and should NOT be recorded as AEs. However, if the pre-existing 
condition worsens in severity, the investigator must report it as an AE. 
 
Each AE should be recorded to represent a single diagnosis. Accompanying signs (including 
abnormal laboratory values) or symptoms should NOT be recorded as additional AEs. If a diagnosis 
is unknown, sign(s) or symptom(s) should be recorded as an AE(s). Changes in laboratory values are 
only considered to be AEs if they are judged to be clinically significant (i.e., if some action or 
intervention is required or if the investigator judges the change to be beyond the range of normal 
physiological fluctuation). If abnormal laboratory values are the result of pathology for which there 
is an overall diagnosis (e.g., increased creatinine in renal failure), the diagnosis only should be 
recorded as an AE. 
 
Pre-planned procedures (surgeries or therapies) that were scheduled prior to the start of AE 
collection are not considered AEs. However, if a pre-planned procedure is performed early (e.g., as 
an emergency) due to a worsening of the pre-existing condition, the worsening of the condition 
should be captured as an AE. Elective procedures performed where there is no change in the 
patient’s medical condition should not be recorded as AEs, but should be documented in the 
patient’s source documents. 
 
The Medical Dictionary for Regulatory Activities (MedDRA) and WHO Drug Dictionary 
(WHODD) will be used to code all AEs and classify all medicines, respectively. All coding will be 
performed by Westat and will be reviewed and approved by the medical monitor. 
 
All AEs, whether serious or not, should be followed to a satisfactory resolution or until the Principal 
Investigator deems the event to be chronic or the patient to be stable and the AE is determined to 
be not clinically significant. 
 
 
8.4 
Assessment of Causality 
The investigator’s assessment of an AE’s relationship to study drug is part of the documentation 
process, but it is not a factor in determining what is or is not reported in the study. If there is any 
doubt as to whether a clinical observation is an AE, the event should be reported.

82 
 
 
 
The relationship or association of the study drug in causing or contributing to the AE will be 
characterized by the investigator using the following classifications and criteria: 
 
Unrelated. This relationship suggests that there is no association between the study drug and the 
reported event. To be deemed unrelated, an alternative etiology must be present. 
 
Possible. This relationship suggests that treatment with the study drug caused or contributed to the 
AE. That is, the event follows a reasonable temporal sequence from the time of drug administration 
and/or follows a known response pattern to the study drug, but could also have been produced by 
other factors. 
 
Probable. This relationship suggests that a reasonable temporal sequence of the event with drug 
administration exists and—based upon the known pharmacological action of the drug, known or 
previously reported adverse reactions to the drug or class of drugs, or judgment based on the 
investigator’s clinical experience—the association of the event with study drug administration seems 
likely. 
 
Definite. This relationship suggests that a definite causal relationship exists between the drug 
administration and the AE and that other conditions (concurrent illness, progression/expression of 
disease state, or concurrent medication reaction) do not appear to explain the event. 
 
 
8.5 
Assessment of Severity 
The intensity of the AE will be rated by the investigator as mild, moderate, severe, or potentially life-
threatening using the following criteria: 
 
Mild (Grade 1): Symptoms causing no or minimal interference with usual social and functional 
activities. 
 
Moderate (Grade 2): Symptoms causing greater than minimal interference with usual social and 
functional activities. 
 
Severe (Grade 3): Symptoms causing inability to perform usual social and functional activities.

83 
 
 
 
Potentially Life-Threatening (Grade 4): Symptoms causing inability to perform basic self-care 
functions OR medical or operative intervention indicated to prevent permanent impairment, 
persistent disability, or death. 
 
Details for grading severity are given in Appendix B. Changes in the severity of an AE should be 
documented to allow an assessment of the duration of the event at each level of intensity to be 
performed. AEs characterized as intermittent require documentation of onset and duration of each 
episode. 
 
 
8.6 
Serious Adverse Event Reporting 
Any AE considered serious by the Principal Investigator according to the previously described 
criteria must be reported using the Westat SAE Report Form and submitted to the Westat 
Regulatory Affairs Department via fax or email within 24 hours of the site becoming aware of the 
event. Site staff must alert Westat of incoming safety information via the Westat SAE Hotline, either 
prior to or immediately after faxing/emailing the SAE Form.

◼ 
Autopsy report 
When an SAE results in hospitalization or prolongation of an existing hospitalization, a copy of the 
hospital admission and discharge summaries and any pertinent laboratory or diagnostic reports 
should be faxed to Westat as soon as they become available. Similarly, documentation of the cause 
of death (e.g., an autopsy report or death certificate) should be submitted to Westat when a death is 
reported. 
 
The investigator should report to Westat any change in the initial SAE Report information or 
additional information that becomes available after the initial SAE Report submission. Each follow-
up SAE Report should be numbered sequentially. 
 
The Sponsor or designee will notify the FDA and all participating Principal Investigators in an IND

◼ 
Findings from animal or in vitro testing: Any finding from animal or in vitro testing, 
whether or not conducted by the Sponsor, that suggest a significant risk in humans 
exposed to the drug, such as reports of mutagenicity, teratogenicity, or carcinogenesis or 
reports of organ toxicity 
◼ 
Increased rate of occurrence of serious suspected adverse reactions. Any clinically 
important increase in the rate of serious suspected adverse reactions over that listed in 
the protocol or investigator’s brochure must also be reported 
The Sponsor or designee will notify the FDA and all participating Principal Investigators of any 
unexpected fatal or life-threatening suspected adverse reaction as soon as possible but no later than 
7 calendar days after the initial receipt of the information. The investigators will follow their 
institutional policies of reporting safety information to the institutional review board (IRB). They 
will provide copies of the correspondence with the ethics committee (EC) to the Sponsor or 
designee for filing. 
 
 
8.7 
Pregnancy 
Sexually active men who have partners of childbearing potential and all females of childbearing 
potential must use an effective method of birth control (e.g., oral contraceptives, double-barrier 
methods, hormonal injectable, implanted contraceptives, or vasectomy) during the study and for 30 
days after the last dose of study drug is administered. 
 
Childbearing Potential. Females of childbearing potential are female patients who are not 
surgically sterile (no history of bilateral tubal ligation, hysterectomy, or bilateral salpingo-
oophorectomy), are not postmenopausal (at least 1 year without menses), and are not otherwise 
sterile by medical evaluation. These patients must use an adequate form of birth control as 
determined by the investigator. Spermicidals are considered one component of a double-barrier 
method. Complete abstinence from sexual intercourse will suffice without additional contraceptive 
measures. However, it is recommended that the Principal Investigator discuss all options with these 
female patients and instruct that if the patient becomes sexually active, she must use appropriate 
contraceptive measures.

Similarly all men who become sexually active during the study with a partner of childbearing 
potential must be instructed to use appropriate contraceptive measures. 
 
Sterile or Postmenopausal. Females who are surgically sterile or postmenopausal will also be 
eligible for the study. Postmenopausal is defined as having had no menses for at least 12 months and 
having an FSH level above 35 IU/L for reproductive-age females. A surgically sterile status is 
defined as having a history of bilateral tubal ligation, hysterectomy, or bilateral salpingo-
oophorectomy. 
 
Suspected Pregnancy. During the study, all females of childbearing potential will be instructed to 
contact the investigator immediately if they suspect they might be pregnant (e.g., late or missed 
menstrual period). Male patients will be instructed to contact the investigator if a sexual partner 
suspects she may be pregnant. 
 
If a patient or investigator suspects that the patient may be pregnant before study drug 
administration, the study drug must be withheld until the results of laboratory pregnancy testing are 
available. If pregnancy is confirmed, the patient must not receive the study drug and must be 
withdrawn from the study. The investigator must immediately notify the medical monitor of a 
pregnancy associated with study drug exposure and record the event on the Pregnancy Surveillance 
Form that will be provided to each site. Protocol-required procedures for study discontinuation 
must be performed on the patient unless contraindicated by pregnancy (e.g., x-ray studies). Other 
appropriate follow-up procedures should be considered if indicated. 
 
The investigator must follow up with a pregnant patient or the pregnant partner of any sexually 
active male patient every 4 weeks while the woman is pregnant and every 4 weeks thereafter to 
follow perinatal and neonatal outcome. The investigator must report follow-up information 
regarding the course of the pregnancy, including perinatal and neonatal outcome, on the appropriate 
Pregnancy Surveillance Form. Infants who result from such pregnancies should be followed for a 
minimum of 8 weeks for safety assurances. 
 
Pregnancy Surveillance Forms will be submitted to the Westat Regulatory Affairs Department via 
the SAE fax line. HHS encourages the reporting of all in utero exposures to antiretroviral agents to 
the Antiretroviral Pregnancy Registry (telephone 800-258-4263 or fax 800-800-1052).

9. Statistical Considerations 
 
9.1 
General Methodology 
The data collected are intended primarily for clinical review and interpretation. The analysis of study 
data will be primarily descriptive, with emphasis on tabular and graphical displays. Descriptive 
statistics will be used to guide decisions as to the clinical relevance of findings. Unless otherwise 
stated, p-values will be determined only if they appear to be warranted from the summary statistics. 
 
For continuous data, descriptive statistics will be presented as number of patients (n), mean, 
standard deviation, median, minimum, and maximum. For categorical data, the frequency and 
percentage of patients in each category will be presented. Percentages will be based on non-missing 
data unless otherwise specified. 
 
Data will be described and analyzed using the SAS System Version 9.3 or later (SAS Institute Inc., 
Cary, NC, SAS System). Individual patient data will be presented in patient data listings. 
 
 
9.2 
Populations for Analysis 
9.2.1 
Efficacy Populations 
9.2.1.1 
Intent-to-Treat Population 
The ITT population is defined as all patients enrolled into the study. Patient disposition will be 
based on the ITT population. The ITT Analysis Population will be used for the primary analysis at 
Day 7. Patients with missing effectiveness data at Day 7 will have their effectiveness set to failure for 
all dichotomous effectiveness variables. This will be referred to as the MEF analysis.

9.2.1.2 
Modified Intent-to-Treat Population 
The modified intent-to-treat (mITT) population is defined as all ITT patients who received at least 
one dose of study drug. The mITT Analysis Population will be used for a supportive effectiveness 
analysis and will include all data without imputing values for missing data.  
 
 
9.2.2 
Safety Population 
All patients who receive at least one partial dose of study drug will be included in the safety dataset 
for analysis (SAF) population. Patients will be analyzed according to the treatment they actually 
received. The safety population will be used for the safety analyses. 
 
 
9.3 
Patient Disposition 
Study completion data will be summarized for all enrolled patients. The number and percentage of 
patients who complete treatment, discontinue study medication prematurely, or discontinue the 
study prematurely, will be tabulated. The primary reason for premature discontinuation of study 
medication and/or discontinuation from study participation will be tabulated. Any additional 
reason(s) for premature discontinuation of study medication will also be tabulated. A listing of all 
enrolled patients will be provided. 
 
 
9.4 
Definition of Baseline 
For patients in Cohort 1 who were enrolled in the TMB-202 or TMB-301 studies, Baseline values 
for TMB-311 are defined as the values recorded for the Baseline visit in the previous study. For 
patients in Cohort 1 who were not enrolled in the TMB-202 or TMB-301 studies, Baseline values for 
TMB-311 are defined as the last values recorded prior to receiving the first dose of ibalizumab. For 
patients in Cohort 2, Baseline is defined as the Day 0 visit of TMB-311 (this study).

Efficacy 
The primary efficacy endpoint (Cohort 2 only) is the proportion of patients achieving a ≥0.5 log10 
decrease in viral load from Baseline to Day 7 along with a 95% confidence interval around the 
observed rate. 
 
Secondary effectiveness endpoints (Cohort 2) include: 
 
◼ 
Proportion of patients with HIV-1 RNA levels <50 copies/mL and <400 copies/mL at 
assessment time points 
◼ 
Mean change from Baseline in viral load at Day 7 and all assessment time points  
◼ 
Proportion of patients achieving a ≥0.5 log10 and ≥1.0 log10 decrease from Baseline in 
viral load at all assessment time points 
Exploratory statistical analyses will explore changes in HIV-1 drug sensitivity/susceptibility to 
determine relationships with protocol-defined virologic failure after ibalizumab administration in 
combination with the OBR.  
 
 
10. Data Handling and Quality Assurance 
 
10.1 
Electronic Case Report Forms 
An EDC will be used to capture data electronically for this trial, meaning that all data will be entered 
in the EDC system from source documents at the investigational site. Case report forms (CRFs) will 
be developed to be used as worksheets. Completion of these worksheets is optional. 
 
A patient ID list will be maintained separately from the research records and will not be recorded or 
stored with the CRFs. 
 
All data must be entered in English. The EDC system should always reflect the latest observations 
on the patients participating in the trial. Therefore, the data are to be entered into the EDC as soon 
as possible during or after the patient’s visit. To avoid inter-observer variability, every effort should

91 
 
 
 
be made to ensure that the same individual who made the initial baseline determinations completes 
all antiviral activity/safety evaluations. The clinical site monitor will verify that all data entries in the 
EDC system are accurate and correct. If some assessments have not been done, or if certain 
information is not available, not applicable, or unknown, the investigator should indicate this in the 
EDC system. The investigator will be required to sign off on the clinical data. 
 
The Sponsor or designee will review the EDC system and evaluate the entries for completeness and 
consistency. The clinical site monitor will compare the data captured in the EDC system with the 
source documents to ensure there are no discrepancies between critical data recorded in the EDC 
system and the source documents. All entries, corrections, and alterations are to be made by the 
responsible investigator or his/her designee. The clinical site monitor cannot enter data in the EDC 
system. Once clinical data in the EDC system have been submitted, corrections to the data fields will 
be marked by an audit trail, meaning that the reason for the change, the name of the person who 
performed the change, and the time and date of the change will be logged. Roles and rights of the 
site personnel responsible for entering the clinical data into the EDC system will be determined in 
advance and documented on the appropriate form. 
 
If additional corrections are needed, the responsible clinical site monitor or project data manager will 
raise a query in the EDC application. The appropriate investigational staff will answer queries sent to 
the investigator. This correspondence will be marked by an audit trail by the EDC application, 
meaning that the name of investigational staff and the time and date stamp are captured for each 
interaction/revision. 
 
 
10.2 
Monitoring of the Study 
The purpose of clinical site monitoring is to ensure that the trial is conducted in an ethically sound 
and scientifically rigorous manner. Specifically, sites will be carefully monitored by the Sponsor or 
designee to ensure that (1) the rights and well-being of participants are protected; (2) data are 
complete, accurate, and verifiable; and (3) the trial is conducted in compliance with the protocol, 
applicable government regulations (e.g., US FDA, Taiwan Food and Drug Administration [TFDA]), 
the ICH E6(R1): Guidelines for Good Clinical Practice, local IRB policies, and current standard 
operating procedures at the sites), and the Sponsor/Sponsor’s representative.

The clinical site monitor, as a representative of the Sponsor, formally evaluates the accuracy and 
completeness of the data collected and assesses compliance with the relevant regulations and 
policies. In doing so, the clinical site monitor will visit the Principal Investigator and study facility 
periodically, in addition to maintaining necessary telephone, email, or letter contact. The clinical site 
monitor will maintain current personal knowledge of the study through observation, review of study 
records and source documentation, and discussion of the conduct of the study with the Principal 
Investigator and staff. 
 
Each investigator is expected to make a reasonable effort to accommodate the clinical site monitor 
when site visits are necessary. Because this trial is utilizing an EDC system, the monitor will need to 
access the data entry computer and internet during the visit. 
 
 
10.3 
Inspection of Records 
Principal Investigators and institutions involved in the study will permit trial-related monitoring, 
audits, IRB review, and regulatory inspection(s) by providing direct access to all study records. In the 
event of an audit, the Principal Investigator agrees to allow the Sponsor, representatives of the 
Sponsor, the US FDA, or other relevant regulatory authorities access to all study records. 
 
The Principal Investigator should immediately notify the Sponsor or designee of any audits 
scheduled by any regulatory authorities and promptly forward, to the Sponsor or designee, copies of 
any audit reports received. 
 
 
10.4 
Study Record Retention 
Essential documents should be retained for at least 2 years after the last approval of a marketing 
application in an ICH region (or longer if mandated by the local IRB). Moreover, they should be 
retained until there are no pending or contemplated marketing applications in an ICH region or at 
least 2 years have elapsed since the formal discontinuation of clinical development of the 
investigational product. However, if required by the applicable regulatory requirements or by an 
agreement with the Sponsor, these documents should be retained for a longer period. It is the 
responsibility of the Sponsor or designee to inform the Principal Investigator or institution as to 
when these documents no longer need to be retained.

11. Administrative Considerations 
 
The following administrative items are meant to guide the Principal Investigator in the conduct of 
the trial but may be changed based on industry and government standard operating procedures, 
working practice documents, or guidelines. Any changes in trial procedures will be reported to the 
IRB, but will not necessarily result in a protocol amendment. 
 
 
11.1 
Confidentiality 
All laboratory specimens, evaluation forms, reports, and other records will be identified in a manner 
designed to maintain patient confidentiality. All records will be kept in a secure storage area with 
limited access. Clinical information will not be released without the written permission of the patient 
(or the patient’s guardian), except as necessary for monitoring and auditing by the Sponsor, its 
designee, the US FDA or applicable regulatory authorities, or the IRB. 
 
The Principal Investigator and all employees and coworkers involved with this study may not 
disclose or use for any purpose, other than performance of the study, any data, record, or other 
unpublished confidential information disclosed to those individuals for the purpose of the study. 
Prior written agreement from the Sponsor or designee must be obtained for the disclosure of any 
said confidential information to other parties. 
 
 
11.2 
Institutional Review Board or Independent Ethics 
Committee Approval 
Federal regulations and the ICH guidelines require that approval be obtained from an IRB/EC 
before participation of human patients in research studies. Before the study onset, the protocol, 
informed consent, advertisements to be used for patient recruitment, and any other written 
information regarding this study to be provided to the patient or the patient’s legal guardian must be 
approved by the IRB/EC. Documentation of all IRB/EC approvals and of the IRB/EC compliance

with ICH E6(R1), US FDA, TFDA, and other applicable regulatory authorities will be maintained by 
the site and available for review by the Sponsor or designee. 
 
The Principal Investigator is responsible for obtaining continued review of the clinical research at 
intervals specified by the IRB, but not exceeding 1 year. The Principal Investigator must supply the 
Sponsor or designee with written documentation of continued review of the clinical research. 
 
 
11.3 
Modification of the Protocol 
This protocol will be implemented as approved by the IRB, and no changes will be implemented 
prior to IRB approval except those necessary to remove an apparent immediate hazard to the 
patient. Amendments to the protocol must be approved by the IRB prior to implementation. 
 
 
11.4 
Informed Consent 
A signed informed consent form, in compliance with Title 21 of the US Code of Federal 
Regulations (CFR) Part 50 and in accordance with other regulations for non-US sites, will be 
obtained from each patient before any study-related procedures are performed and any personal 
information is collected. An informed consent template may be provided to investigative sites by the 
Sponsor or designee. The consent must be reviewed by the Sponsor or designee before IRB 
submission if the site proposes or makes any institution-specific modifications to study-related 
procedures, the risk language, or any other significant changes that would alter the information 
relayed. Once reviewed, the consent will be submitted by the Principal Investigator to his/her IRB 
for review and approval before the start of the study. If the informed consent form is revised during 
the course of the study, all active participating patients must sign the revised IRB-approved consent 
form. 
 
Before enrollment, each prospective patient will be given a full explanation of the study and allowed 
to read the approved informed consent form. The information given should be in a language or 
manner that is easily understandable to the participant or legal guardian. Once the Principal 
Investigator is assured that the patient/legal guardian understands the implications of participating 
in the study and has been given the proper time to consider whether to participate or not, the

patient/legal guardian will be asked to give consent to participate in the study by signing the 
informed consent form. The Principal Investigator will also sign the form at that time. 
 
The Principal Investigator will provide a copy of the signed informed consent form to the patient 
and/or legal guardian. The original form will be maintained in the patient’s medical records at the 
site. 
 
 
11.5 
Protocol Violations and Deviations 
A deviation from the protocol is an unintended and/or unanticipated departure from the procedures 
and/or processes that were approved by the Sponsor and the IRB, and that were agreed to by the 
Principal Investigator. Deviations usually have an impact on individual patients or a small group of 
patients and do not involve inclusion/exclusion or primary endpoint criteria. A protocol violation 
occurs when (1) there is non-adherence to the protocol that results in significant additional risk to 
the patient, (2) the patient or Principal Investigator has failed to adhere to significant protocol 
requirements (e.g., inclusion/exclusion criteria), or (3) there is non-adherence to FDA regulations 
and/or ICH E6(R1) guidelines. 
 
For this protocol, violations will be defined as exceptions to the inclusion or exclusion criteria, 
situations where a patient is required to withdraw but the investigator believes the patient should 
remain in the study, and the use of an excluded concomitant medication. All other departures from 
the protocol (e.g., missed visit windows, laboratory samples not collected on the required day) will 
be documented as protocol deviations. The Principal Investigator or designee must document and 
explain any protocol deviation or violation in the patient’s source documentation. The investigator 
should notify the IRB of all protocol violations and deviations per local institutional policy. Protocol 
deviations and violations will be documented by the responsible clinical site monitor during 
monitoring visits, and those observations will be reviewed with the investigator. 
 
The Principal Investigator may implement a change from the protocol without prior Sponsor and 
IRB approval only to eliminate an immediate hazard to a patient. The implemented change should 
be submitted to the IRB for review as soon as possible. 
 
If the investigator believes that an exception to the protocol is justified for an individual patient, the 
investigator may present the facts and rationale to the medical monitor and request a one-time

exception. This request will be submitted in writing on a protocol inquiry form, which will be faxed 
to the medical monitor for review and disposition. The medical monitor will then fax the decision to 
the investigator regarding approval or denial of the request. This written documentation must be 
filed in the investigator’s study file. 
 
This process will apply if the investigator believes that a patient should receive an excluded 
concomitant medication and remain in the study, or if the investigator believes that a patient should 
remain in the study when the protocol dictates that the patient should be discontinued. The 
implemented change should be submitted to the IRB for review as soon as possible. However, it is 
the policy of the Sponsor that there will be no exceptions granted concerning the inclusion and 
exclusion criteria. 
 
 
11.6 
Study Reporting Requirements 
By participating in this study, the Principal Investigator agrees to submit reports of AEs according to 
the timeline and method outlined in the protocol. In addition, the Principal Investigator agrees to 
submit periodic reports to his/her IRB as appropriate. 
 
 
11.7 
Financial Disclosure and Obligations 
Principal Investigators and subinvestigators are required to provide financial disclosure information 
to allow the Sponsor or designee to submit the complete and accurate certification or disclosure 
statements required under Title 21 CFR 54. In addition, the Principal Investigator and 
subinvestigators must provide the Sponsor or designee with a commitment to update this 
information promptly, if any relevant changes occur during the course of the investigation and for 1 
year following the completion of the study. 
 
The Sponsor or designee is not financially responsible for further testing/treatment of any medical 
condition that may be detected during the Screening process. In addition, in the absence of specific 
arrangements, the Sponsor or designee is not financially responsible for treatment of the patient’s 
disease.
