4.  Justification 
 
HIV-infected patients can live longer thanks to effective antiretroviral treatment. In addition, efforts 
are being made to diagnose people who may be infected with HIV as soon as possible, and the 
initiation of antiretroviral treatment is increasingly recommended and at earlier stages. 
 
On the other hand, antiretroviral treatment must be administered indefinitely. All these factors have 
contributed to the incessant increase in the budget for antiretroviral treatment, in such a way that its 
provision free of cost represents a major challenge for public health systems even in developed 
countries such as Spain (1, 2). 
 
The combination of efavirenz/tenofovir/emtricitabine has been the most frequently used 
contemporary treatment in clinical trials in people with no prior experience of antiretroviral treatment, 
and no other treatment regimen has shown superiority in efficacy against it 
(3). This combination is available as a fixed-dose combination in a single pill (ATRIPLA),® which 
represents the simplest antiretroviral regimen in Spain today. In the short term, there may be 
tolerability problems, neuropsychological side effects that are usually of little intensity and that in 
many cases resolve after the first four weeks of treatment (4). In addition, a small proportion of 
patients with well-identified risk factors such as older age, low CD4, low weight weight, nephrotoxic 
drugs, and underlying kidney disease may experience a progressive risk of tenofovir-associated 
renal dysfunction (5) that usually improves with discontinuation of tenofovir. There is evidence to 
suggest an association between increased bioavailability of efavirenz or tenofovir and the risk of 
developing side effects due to these drugs. For most patients on chronically stable treatment with 
ATRIPLA®, serious long-term side effects are not expected. ATRIPLA® has shown a better cost-
effectiveness balance than other antiretroviral regimens (6). For all these reasons, ATRIPLA® has 
become one of the most popular antiretroviral regimens. At the end of 2011, approximately 25% of 
active patients (n=4400) treated at the Hospital Clínic de Barcelona were treated with ATRIPLA,® 
making this regimen the most frequently prescribed antiretroviral treatment. Currently, more than 
1000 patients are receiving virologically effective treatment with ATRIPLA® at the Hospital Clínic de 
Barcelona, of which 75% have been on this treatment for more than two years.

Since antiretroviral treatment has to be taken indefinitely, the search for strategies to simplify it has 
been an important element in the development of antiretroviral regimens. The simplification of 
antiretroviral treatment in patients with sustained virologic suppression represents a strategy 
accepted by most therapeutic recommendations (7). The longer the viral suppression lasts, the 
greater the probability of maintaining sustained virological success (8-11). In patients with sustained 
virologic suppression, the absolute risk of virologic failure is low, and regimens with non-nucleoside 
reverse transcriptase inhibitors have consistently shown better virologic outcomes than regimens 
with protease inhibitors. Strategies to simplify antiretroviral treatment have aimed to minimize the risk 
of toxicity, seek greater convenience, and more recently reduce the cost of antiretroviral. 
 
Although ATRIPLA® is the simplest antiretroviral regimen at present, there is potential for further 
simplification. Each of the individual components of ATRIPLA® has the longest half-lives of all 
currently available antiretrovirals: 40-55 hours for plasma efavirenz (12), 39 hours for intracellular 
emtricitabine triphosphate, and 150 hours for intracellular tenofovir diphosphate (13). In a 
discontinuation study, efavirenz plasma levels were estimated to exceed the adjusted IC95 for 
protein concentration (46.7 ng/mL) for a median of 6.7 days (IQR 4.7-9.2) after the last dose of 
efavirenz (14). Clinical information is available on the dosing of efavirenz at dose intervals greater 
than once daily (PHOTO study). The FOTO study was a 48-week observational study in which 30 
patients with virologic suppression (<50 copies/mL) for at least three months prior to the study 
switched their usual antiretroviral treatment from a daily dose to a weekly schedule of 5 consecutive 
days on treatment (usually Monday through Friday) followed by 2 days without treatment (usually on 
the weekend) (15). Overall, virologic suppression was maintained in 90% of patients. More 
interestingly, however, ten of the 30 patients included were taking efavirenz along with tenofovir and 
nucleoside reverse transcriptase inhibitors with long half-lives such as didanosine or lamivudine, and 
none of these showed virologic failure. Following these promising results, researchers in the FOTO 
pilot study designed a 24-week open-label randomized study in which treatment with ATRIPLA® for 
five days a week would be compared to the standard dose of ATRIPLA® once a day 
(NCT00414635). So far, we have no information that results of this study have been reported. 
 
In our daily practice, we have detected at least two patients on chronic treatment with ATRIPLA® 
who, for personal reasons, different in each case, decided to take the dose every other day instead 
of the standard daily dosage for more than 6 and 12 months respectively, without the plasma viral 
load having become detectable in any of them. On the other hand, a small preliminary survey of a 
randomly selected sample of 36 consecutive patients treated with ATRIPLA® for more than 2 years, 
who claimed to have no tolerability problems and with a persistently undetectable viral load during 
that period of time, showed that 78% saw a dose reduction to three days per week as more favorable 
than the standard daily dose.  14% did not care, and only 8% did not want to change their dosage, 
their main reasons being the fact that they were already fine as they were and the fear that they 
could lose the undetectability of the plasma viral load. 
We intend to evaluate the possibility of effective simplification by moving from the standard daily 
dose of ATRIPLA® to a three-day-weekly dose in patients with sustained virologic suppression. 
Although antiretroviral treatment regimens have not so far contemplated dosing with intervals greater 
than once a day, the dosing of three times a week in the same way as that proposed in this project 
has been used with a high degree of compliance in the prophylaxis of P. jirovecii  pneumonia in HIV-
infected patients (16,  17). 
 
Reducing the dosage of the most widely used antiretroviral treatment regimen as proposed in this 
project would reduce expenditure by 57%. In the case of the Hospital Clínic alone, this reduction in 
expenditure would mean going from 7.4 to 4.2 million euros per year. Since ATRIPLA® represents 
one of the most widely used regimens, the dose reduction strategy 


A-TRI-WEEK Trial 
EudraCT number: 2012-004970-24 
Protocol version 1.0 of 30 October 2012

could have a considerable impact on the budget for antiretroviral treatment within the policy of 
containing health expenditure promoted by the Spanish health authorities and more necessary today 
than ever in the current context of economic crisis (18). In addition, it can help reduce your already 
low risk of chronic toxicity. Finally, dose reduction is considered a popular measure and positively 
evaluated by a high proportion of treated patients. If our project obtains favorable results that support 
the dosage reduced to three days per week, the experimental regimen would become the simplest 
and cheapest among all the currently available regimens, including monotherapy with protease 
inhibitors. 
 
Determination of plasma viral load and CD4 and CD8 cell counts have been key tools for clinical 
research and healthcare of HIV-positive patients until now. However, in patients with persistently 
undetectable viral load and relatively high CD4 counts, the simple determination of viral load and cell 
populations is unlikely to allow a fine distinction between the possible virological and immunological 
consequences of the dose reduction strategy to be evaluated. Therefore, viral reservoir analysis by 
determining proviral DNA and especially the proportion of that reservoir that produces viral particles 
can provide more detailed information on the virological safety of the new strategy (19). Similarly, the 
determination of plasma viral load using the most sensitive technique ("single copy assay" (limit of 
detection 1 copy/mL) (20) can discriminate whether this dose-reduction strategy produces any 
impact on viral replication that cannot be detected by the standard technique used in routine clinical 
practice. On the other hand, the extensive immunological study that is intended to be carried out 
(population analysis of the T lineage that includes its activation status and thymic production, among 
others) will allow us to exhaustively monitor the effects of any changes that may occur at this level on 
the study population (21-23). Therefore, we consider that the efficacy and safety of the dose 
reduction strategy of the efavirenz/tenofovir/emtricitabine regimen should be evaluated as 
consistently as possible with the previously mentioned virological and immunological tests. 
 
Our study aims to conceptually confirm whether dose reduction of ATRIPLA® is feasible as a 
strategy and whether it entails any virological or immunological risk. If the results of this study are 
positive, they could form the basis for a randomized clinical trial of sufficient size to attempt to 
validate this strategy for future clinical use.

5.  Objective and Purpose of the Trial 
Main: 
The primary objective of this study is to determine the feasibility of maintaining virologic suppression 
on standard plasma viral load (limit of detection 37 copies/mL) of a once-daily dose reduction 
strategy of ATRIPLA® to three tablets per week in HIV-1-infected patients with sustained standard 
plasma viral load suppression for more than 2 years.

Side: 
● 
Virological study including: ultrasensitive viral load in plasma (limit of detection 1 copy/mL), and 
HIV-1 reservoir in peripheral blood mononucellar cells, 
 
● 
Immunological study including: production of TRECs, immune profile of activation (CD38 and 
HLA-DR) and senescence (CD57 and CD28) in CD4 and CD8 lineages, apoptosis (annexin V 
staining), and ratios of naïve T cells and effectors and memory cells (CCR7 and CD45RA).

cholesterol and HDL) at the beginning and end of the study, as well as general tolerability. 
 
 
6.  Trial Design 
Open-label study, Phase IV, pilot, prospective single-center. 
 
 
6.1 Primary and Secondary Endpoints 
Primary Endpoint: 
The primary endpoint of the study will be the proportion of patients who continue to have a standard 
plasma viral load (<37 copies/mL) at 24 weeks by intention-to-treat analysis. 
 
Secondary endpoints: 
1) The proportion of patients with ultrasensitive viral load (<1 copy/mL) after 24 weeks. 
 
2) The change from baseline to 24 weeks in the viral reservoir of peripheral blood mononuclear 
cells 
 
3) Changes from baseline to 24 weeks in TREC production, immune profile of activation (CD38 
and HLA-DR) and senescence (CD57 and CD28) in CD4 and CD8 lineages, in naïve and effector 
and memory T cell ratios (CCR7 and CD45RA), and changes in apoptosis levels in vitro by 
annexin V staining. 
 
4) Changes in plasma levels of efavirenz. 
 
5) Changes in sleep quality (Pittsburgh Sleep Quality Index), plasma levels of vitamin D and lipids, 
and estimated glomerular filtration rate. 
 
6) Overall safety (reporting side effects, serious side effects, and discontinuation of treatment due 
to side effects) 
 
 
6.2 Design 
Although the hypothesis of the study has been based on various congruent information that allow us 
to face with sufficient guarantee the feasibility of the study and the eventual demonstration of the 
virological and immunological efficacy of the ATRIPLA® dose reduction strategy, we are not 
absolutely certain that an unacceptably high virological failure rate (standard viral load ≥37 
copies/mL on two consecutive occasions) can occur in the arm 


A-TRI-WEEK Trial

experimental. We will consider a priori that the failure of at least 20% (n=6) of the patients in the 
experimental arm will represent an unacceptably high virological failure rate. In this case, its 
conclusion will be considered premature. In this extreme case, the data of the patients already 
included up to the time of the premature conclusion of the study would be analyzed. 
The present study is proposed as a proof of concept to be able to formulate another study with a 
sufficiently large sample size to adequately demonstrate the non-inferiority of the strategy. The 
results of the present study can help to design the non-inferiority study and to estimate its sample 
size.

6.3 Guidelines for Dose Modification 
Grade 1 and 2 AEs require close follow-up but no change in treatment. 
 
All grade 3 toxicities will be treated by the facility investigator as appropriate. Any grade 4 toxicity 
that, in the opinion of the investigator of the center, is directly related to the treatment of the study, 
will be treated with the permanent suspension of the study. 
 
 
6.4 Trial Treatments 
DRUG SUPPLY AND LABELLING 
 
This study will use a drug already on the market and authorized for use in HIV-infected patients; The 
study drug is already taken regularly by these patients and will be distributed by the Pharmacy 
service of the Hospital Clínic. For clinical trials carried out in Spain, labelling in Spanish is mandatory 
in accordance with the regulations currently in force. 
 
 
6.5 Trial duration 
The approximate expected duration for the inclusion of patients is 12 months, and the duration of 
treatment and follow-up of the included patients will be extended by a maximum of 24 weeks

6.6 Termination and/or discontinuation criteria 
The treatment will be compulsorily terminated during the study for any of the following reasons: 
 
● 
Virologic failure, defined by two consecutive determinations of standard viral load >37 copies/mL 
separated by one week from each other. 
● 
I express the patient's wish. 
● 
Medical decision. 
● 
Death. 
● 
Pregnancy detection during the study. 
 
Treatment may be terminated during the study for any of the following reasons: 
● 
The medical investigator determines that a SAE is possibly or likely related to the study drug. 
● 
Failure to administer, evaluate, or other study requirements. 
 
If the confirmatory result is ≥37 copies/mL, a genotypic resistance detection study would be 
scheduled and the most appropriate attitude towards modifying their antiretroviral treatment would be 
discussed with the patient. In this case, unless he or she is against it, the patient would continue in 
the study. 
All other virologic studies and immunological studies should be determined exclusively at baseline 
and 24 weeks (except if there is earlier virologic failure, in which case it would be performed at the 
time of confirmation of failure rather than at 24 weeks), and their determination should be deferred at 
the end of the study. To this end, plasma and peripheral blood mononuclear cell samples should be 
stored appropriately at -80°C until the planned determinations are made. 
 
 
6.7 End of rehearsal 
The end of the trial will be considered the time of the last visit of the last subject recruited.

9.  Effectiveness Assessment 
9.1 Efficiency parameters 
 
 
Virological tests 
a. 
Determination of viral load 
Standard determination of viral load (detection limit 37 copies/mL) Virologic failure will be 
defined as: 
In case of detection of plasma viral load (≥37 copies/mL), the determination of plasma viral 
load should be repeated during the following week for confirmation. If the result of the 
confirmatory determination is ≥37 copies/mL 
 
 
 
b. 
Methods of Analysis and Sensitivity 
The standard HIV-1 viral load in the plasma sample will be previously performed using the 
commercial VERSANT HIV-1 RNA 1.0 Assay (kPCR) (SIEMENS HEALTHCARE 
DIAGNOSTICS) technique with a sensitivity of up to 37 copies/mL. The manufacturer's 
recommendations will be followed.

Protocol version 1.0 of 30 October 2012

Ultrasensitive viral load (detection limit 1 copy/mL) 
 
By ultracentrifugation (170000g, 30 minutes, 4ºC) the HIV-1 virions present in 7mL of plasma will be 
concentrated, a volume to which will have been added a known concentration of an RNA transcript 
used as a non-competitive internal control for the monitoring of ultracentrifugation, extraction and 
amplification processes. The supernatant will be removed leaving a residual volume of 200 L, from 
which the viral RNA will be extracted using the commercial QIAamp MinElute Virus Spin (QIAGEN) 
kit, following the manufacturer's recommendations. The RNA obtained will be aliquoted and frozen at 
-80ºC until use. The ultrasensitive quantification of the HIV-1 viral load will be performed by means of 
a one-step RT-PCR duplex in real time, using the STRATAGENE Mx3005P platform. For the 
amplification and detection of a conserved region of the HIV-1 gag gene, the primers and probes 
previously described by Palmer et al (2003) will be used. To detect the non-competitive internal 
control added to the sample, a set of specific primers and probe described above will be used 
(Almansa et al [PMID 21880131], Anton et al [PMID 20955912]). To carry out the quantification of 
the HIV-1 viral load and the internal control, two standard lines of serial dilutions from a known 
concentration of a standard will be amplified in parallel, one for the determination of the HIV-1 viral 
load and the other for internal control. Each quantification test will be performed in triplicate for each 
of the samples and for each of the dilutions of the standard line. In each of the tests, negative 
plasma samples will be used as a target to minimize the impact of possible contaminations in some 
of the steps of the process. For the quantification (copies/mL) of HIV-1 viral load, only those results 
within the linear range of the assay (R>0.95) will be considered. Initially, the result of the HIV-1 viral 
load will be validated in those samples where the recovery of internal control is greater than 55%, as 
described by Palmer et al (20), although this must be previously demonstrated in the process of 
optimizing our methodology. 
 
The specific PCR product obtained with the primers specific for a conserved region of the gag gene 
previously described by Palmer et al (20) will be cloned into a pGEM-T Easy Vector (PROMEGA) 
plasmid that will be linearized by the restriction enzyme SpeI (NEW ENGLAND BIOLABS). This 
plasmid, which contains a T7 promoter for RNA polymerase, will be transcribed in vitro using the 
commercial MEGAscript Kit (AMBION). Purification of the RNA transcript obtained as a standard 
control for HIV-1 quantification will be performed using the commercial MEGAclear Kit (AMBION). 
The concentration and integrity of the RNA transcript obtained will be determined using the 
BioAnalyzer (AGILENT) platform. From a known concentration of this standard standard, a bank of 
dilutions will be generated to determine the efficiency, linearity range and lower limit of sensitivity. 
 
The RNA transcript used as an internal control, based on a conserved region of the coding sequence 
of the M1 protein of the influenza A virus, has previously been used in the quantification of the 
influenza A (H1N1) pdm09 virus in our laboratory (Almansa et al [PMID 21880131], Anton et al 
[PMID 20955912]). For its synthesis, the methodology described in the previous section was 
followed. The percentage of internal control, added to the plasma sample prior to ultracentrifugation, 
which is recovered and from which we will consider the results of the HIV-1 viral load valid, will be 
validated in our laboratory, initially considering as good the 55% recovery previously described by 
Palmer et al (20). 
B) HIV-1 viral reservoir study: 
The study of the viral reservoir will be determined based on the methodology initially described by 
the group of Nicholas Chomont (19) modified by the Laboratory of Dr José Alcamí. It will be made 
from 50 X 106 frozen peripheral blood mononuclear cells. A purification of CD4+ T-cells by negative 
depletion will be performed. These purified cells will be activated in the presence of anti-CD3/CD28. 
The culture should be maintained for 9 days in the presence of a cocktail of antiretrovirals 
(zidovudine, efavirenz, and raltegravir) to prevent further rounds of infection and a reactivation of 
viral production. Finally, viral production will be quantified at 3, 6 and 9 days, from the supernatant of 
the cultures, by ultrasensitive RT-qPCR and p24 antigen assessment by capture ELISA.

C) Immunological studies: 
 
The study of activation markers in the different CD4 and CD8 lymphocyte subpopulations will be 
carried out by extracellular staining with conjugated antibodies for subsequent analysis by flow 
cytometry. 
 
The detection of cleaved circular DNA (TRECs) after genetic rearrangement of the T cell receptor 
(TCR) will be carried out by the usual methods (real-time PCR). 
Determination of apoptosis will be performed using the annexin V staining method. 
D) Pharmacokinetics 
 
All patients will be proposed to be included in the pharmacokinetic substudy. At baseline, each of 
them should have their plasma levels determined in efavirenz in the morning before the next daily 
dose. 
 
This determination will be repeated at week 24 of treatment. For patients who continue with the daily 
treatment, the extraction will be carried out any day in the morning; and for those randomized to 
receive ATRIPLA® on Monday, Wednesday and Friday, the extraction will be carried out on a 
Monday morning because it is the day of the week when the plasma concentration of efavirenz must 
be lower due to the maximum dose interval. 
 
E) Safety 
To evaluate sleep quality, the "Pittsburgh Sleep Quality Index" will be carried out, available in its 
validated Spanish version (http://www.medigraphic.com/pdfs/gaceta/gm-2008/gm086e.pdf). 
 
The plasma concentration of vitamin 25OHD3 will be determined by immunoassay. 
 
The estimated glomerular filtration rate will be calculated using the usual formula, available in 
http://www.nephron.com/MDRD_GFR.cgi . 
 
 
10.  Safety Rating 
10.1 Detection and recording of Adverse Events 
It is the investigator's responsibility to detect and document any event that meets the criteria and 
definitions of adverse event (AE) or serious adverse event (SAE) as set forth in this protocol. During 
the study, the existence of adverse events, whether serious or not, will be checked in accordance 
with the definition given in this section of the protocol. 
 
a) Minimum information to be specified: 
Description/definition: 
Adverse event (AE) is any adverse health event in a patient or clinical trial subject treated 
with a medicine, even if it is not necessarily causally related to that treatment. Therefore, it can be 
any unfavorable and unintended signs (including an abnormal laboratory finding), symptom, or 
illness temporarily associated with the use of an investigational drug, whether or not related to the 
investigational drug. 
Laboratory abnormalities of clinical importance that meet one or more of the following criteria are 
also considered AEs: 
 
● 
It requires additional intervention or treatment. 
● 
Requires a modification of the dose. 


A-TRI-WEEK Trial 
EudraCT number: 2012-004970-24 
Protocol version 1.0 of 30 October 2012 
20 
 
 
● 
It is accompanied by a clinical manifestation. 
 
Any analytical anomaly that the investigating physician considers to be of clinical importance must be 
recorded as such in the printed copy of the laboratory report, indicating the physician's initials and 
the date of revision. An AA is also considered to be any event associated or observed in conjunction 
with an accidental or intentional overdose of the product, or with abuse or withdrawal of the product. 
 
All AEs will be recorded in the subject's medical record and in the eCRDe. The start and end dates 
of each AA, the intensity and the relationship with the study drug will be recorded. 
 
The criteria for subject treatment, dose discontinuation, dosage adjustment, withdrawal, or treatment 
changes will only apply to toxicities attributable to the study drugs (i.e., efavirenz, tenofovir, and 
emtricitabine). 
 
The classification system for drug toxicity is set out in the DAIDS Table for Grading the Intensity of 
Adverse Events in Adults and Children, which can be found on the DAIDS RSC website: 
http://rsc.tech-res.com/safetyandpharmacovigilance/. 
 
In addition, for each AA, the measures taken or the outcome (e.g. hospitalization, discontinuation of 
treatment) will be recorded. 
 
 
Adverse reaction (AR) is any harmful, unintended reaction to an investigational drug, 
regardless of the dose administered. In this case, there is a suspicion of a causal relationship 
between the investigational drug and the adverse event. 
Serious adverse event (SAE) is any adverse event that, at any dose, results in death, 
threatens the life of the subject, makes hospitalization necessary or prolonged hospitalization, results 
in permanent or significant disability or disability, or results in a congenital anomaly or malformation. 
For the purposes of notification, suspected adverse events that are considered medically significant, 
even if they do not meet the above criteria, will also be treated as serious, including major medical 
events that require intervention to prevent one of the consequences described above from occurring. 
Likewise, all suspected transmission of an infectious agent through a drug will be reported as 
serious. Examples of these events include allergic bronchospasm requiring intensive treatment in an 
emergency department or at the individual's home, blood dyscrasia or seizures that do not require 
hospitalization, or the development of drug dependence or abuse. 
 
Medical and scientific judgement should be used to decide whether other situations that have not 
resulted in the outcomes listed in the above definitions should be reported as SAGs. 
 
A life-threatening term is defined as a situation where, in the opinion of the physician, the patient at 
the time of the adverse event or adverse reaction is at real risk of death. 
 
Hospitalization or prolongation of a hospitalization is a criterion for considering an AA to be serious. 
Only admission in which the patient spends the night in the hospital should be considered as 
hospitalization. The following situations will not meet the AAG criteria: 
 
- 
if hospitalization or prolongation of hospitalization is necessary to perform a procedure 
required by the protocol (for example, if day or night visits will be made for biopsies or 
surgeries required by the protocol). 
 
- 
if hospitalization or prolongation of hospitalization is part of the facility's routine procedure 
(e.g., removal of a stent after surgery) 


A-TRI-WEEK Trial 
EudraCT number: 2012-004970-24 
Protocol version 1.0 of 30 October 2012 
21 
 
 
- 
in case of scheduled hospitalization for a pre-existing process that has not worsened (e.g. 
scheduled hospitalization for the implantation of a knee prosthesis for a previous 
osteoarthritis process) 
 
 
Grade IV laboratory alterations will be considered AAG. 
 
DO NOT confuse the concept of "serious" with "severe" which refers to the intensity of the adverse 
event or adverse reaction. 
 
Unexpected serious adverse reaction (RAGI) is a serious adverse reaction whose nature 
or severity does not correspond to the information regarding the product (for example, the 
investigator's manual in the case of an investigational medicinal product not authorised for marketing 
or the product label in the case of an authorised medicinal product). 
 
b) Imputability criteria. 
The causal relationship between the investigational product and the occurrence of AA/AAG shall be 
established on the basis of clinical judgment. To this end, other causes will be considered and 
studied, such as the natural history of the underlying diseases, concomitant treatment, other risk 
factors and the temporal relationship of the event with the investigational product. In addition, the 
technical data sheet of the products will be consulted. 
 
In order to analyse the possible cause-effect relationship, the temporal relationship between the 
administration of the drug and the AA, possible alternative causes, the evolution (complete 
remission, partial recovery, death, sequelae, persistence), persistence or not after the suspension of 
administration, reappearance with the readministration of the product or the prior knowledge of said 
event coinciding with the known or expected response pattern of the drug under study will be 
considered. 
 
The causal relationship of an AA with the medication under study will be established according to the 
following definitions: 
 
Unlikely relationship: The adverse event does not occur after a plausible chronological 
sequence related to the administration of the product under study and/or is reasonably explainable 
by other factors, such as the patient's clinical status or other concomitant therapeutic, toxic, or 
environmental interventions. In addition, it does not match the known or expected response pattern 
of the drug. 
Possible relationship: the adverse event occurs after a plausible chronological sequence 
related to the administration of the product under study, but can also be explained by the patient's 
clinical status or other concomitant therapeutic, toxic, or environmental interventions. It also matches 
the known or expected response pattern of the drug. 
 
Probable relationship: The adverse event occurs after a plausible chronological sequence 
related to the administration of the product under study, cannot be reasonably explained by the 
patient's clinical status or other concomitant therapeutic, toxic, or environmental interventions, and 
after withdrawal or reduction of the dose of the suspect drug the event follows a logical clinical 
sequence. It also matches the known or expected response pattern of the drug. 
 
Very likely relationship: the adverse event occurs after a plausible chronological sequence 
related to the administration of the product under study, cannot be reasonably explained by the 
clinical status of the patient or other concomitant therapeutic, toxic or environmental interventions, 
after withdrawal or reduction of the dose of the suspect drug the event follows a logical clinical 
sequence and it is necessary that after the readministration of the suspicious drug the adverse event 
reappears. It also matches the known or expected response pattern of the drug. 


A-TRI-WEEK Trial 
EudraCT number: 2012-004970-24 
Protocol version 1.0 of 30 October 2012 
22 
 
 
Unrelated: Adverse event clearly due to causes unrelated to the medication under study and 
the criteria for another causal relationship are not met. 
 
Non-assessable relationship: any notification that suggests an adverse effect, which 
cannot be judged because the information is insufficient or contradictory and which cannot be 
supplemented or verified. 
 
10.2. Notification 
The investigator or designee must notify all AAGs, regardless of whether or not they are 
considered drug-related or planned, to the head of the CTU. Dr. Anna Cruceta 
(acruceta@clinic.ub.es) tel 2275400 ext 4380 and fax 932279877 in order to notify local and national 
health authorities within one working day of becoming aware of the event., so that the contact of 
the designated promoter can prepare the corresponding written report. AAGs occurring will be 
reported at any time from the subject's inclusion in the study and up to 30 days after the study has 
been completed or discontinued. In the specific case of selection failure, the AAGs will be recorded 
from the moment the consent is signed until the subject is considered a selection failure. 
Regardless of the classification of adverse effects, the Investigator must collect all the AEs in the 
corresponding section of the study data collection notebook (CRD) and fill in all the information 
pertaining to them. 
The sponsor must notify in an EXPEDITIOUS manner all relevant SAFETY INFORMATION, i.e. that 
could modify the risk/benefit ratio of the investigational medicine, or determine changes in its 
administration schedule or in the conduct of the trial, for example: 
- a qualitative change or an increase in the percentage of occurrence of expected RAGs, which is 
considered clinically important. 
- RAGIs that occur after the completion of a clinical trial and that are notified by the investigator to 
the sponsor. 
-New developments related to the conduct of the trial or the development of the investigational 
medicinal product and likely to affect the safety of the subjects, such as: 
• 
Serious adverse events that may be associated with the trial procedures and may modify 
the conduct of the trial 
• 
A significant risk to subjects such as the lack of efficacy of an investigational drug used for 
the treatment of a life-threatening disease. 
• 
Important new safety findings from new animal studies (such as cardiogenicity). 
• 
Any premature termination or temporary halt of a clinical trial with the same investigational 
medicinal product for safety reasons, carried out in another country and by the same 
sponsor. 
• 
GRAs related only to an MNI that are considered relevant as they are not subject to RAGI's 
general rules of expedited reporting of individual cases. 
- Any recommendations from the data monitoring committee, which are relevant to the safety of the 
subjects. 
This information must be notified as soon as possible and no later than 15 days after the promoter 
has become aware of it. In addition, if additional information that is relevant is obtained, it must be 
notified as quickly as possible.

10.3 Evaluation of toxicity parameters 
The classification system for drug toxicity is set out in the DAIDS Table for Grading the Intensity of 
Adverse Events in Adults and Children, which can be found on the DAIDS RSC website: 
http://rsc.tech-res.com/safetyandpharmacovigilance/. 
 
Treatment of ATRIPLA side effects 
 
 
The dose reduction levels of ATRIPLA® are indicated in the summary of product characteristics. (see annexes to 
the protocol) 
 
 
 
10.4 COMMUNICATION TO RESEARCHERS 
The sponsor shall communicate to investigators any information that may affect the safety of the trial 
subjects as soon as possible. 
 
It is advisable when deemed appropriate that information on serious and unexpected adverse 
reactions (RAGI) be presented in a list together with a brief analysis of the data provided. 
Researchers must also be informed of the safety aspects that impact the conduct of the clinical trial 
or the development of the product. Including disruption of the development program or security-
related protocol modifications. 
 
Follow-up of subjects after adverse events will be performed by clinical and complementary 
examinations necessary for the duration of treatment and then on a monthly basis during follow-up 
and up to 30 days after the end of treatment. In the event of a possible pregnancy, the health status 
of both the mother and the newborn will be monitored during the trial, whether the person who has 
become pregnant is the one who is taking the investigational drug or if it has been taken by her 
partner. 
No interim analyses are planned for the present study. 
 
 
11.  Statistics 
11.1 Sample 
The study will be carried out in 60 patients. This is a proof of concept and does not require an ad-hoc 
sample size calculation. 
 
11.2 Sample size 
 
11.3 Analysis 
 
Comparison of patient proportions will be performed using Fisher's exact test and the 95% confidence 
interval will be calculated for the difference in proportions. 
 
Quantitative data at baseline and after 24 weeks, as well as absolute and relative changes at 24 
weeks, will be compared using the Wilcoxon rank sum test. The point estimate and 95% confidence 
interval of the difference in medians will be estimated using the Hodges-Lehman methodology using 
the Moses free distribution. 
Correlations between continuous variables will be evaluated using Spearman's rank correlation test.

Protocol version 1.0 of 30 October 2012 
24 
 
 
The study of baseline predictors of response will be carried out by means of a multivariate analysis 
of multiple logistic regression. 
 
Limitations of the study: 
 
Although the hypothesis of the study has been based on various congruent information that allow us 
to face with sufficient guarantee the feasibility of the study and the eventual demonstration of the 
virological and immunological efficacy of the ATRIPLA® dose reduction strategy, we are not 
absolutely certain that an unacceptably high virological failure rate (standard viral load ≥37 
copies/mL on two consecutive occasions) may occur in the experimental arm.  We will consider a 
priori that the failure of at least 20% (n=6) of the patients in the experimental arm will represent an 
unacceptably high virological failure rate. In this case, its conclusion will be considered premature. In 
this extreme case, the data of the patients already included would be analyzed. 
 
This study, even with the most favorable virologic and immunological results, would not constitute 
definitive proof of the safety and efficacy of ATRIPLA'® s dose reduction strategy. The present study 
is only a proof of concept and another study with a sufficiently large sample size would be needed to 
adequately demonstrate the non-inferiority of the strategy. The results of the present study can help 
to design the non-inferiority study and to estimate its sample size. 
 
 
11.4 Completion Criteria 
The study will be considered to have been completed on the date of the last visit of the last subject 
recruited into the study. 
 
11.5 Processing of lost data 
Missing data imputation techniques will not be used. Only the available data will be analyzed. 
 
11.6 Deviations from the statistical plan 
Any deviation from the planned statistical analyses will be justified and detailed in the reports derived 
from the processing of the data. 
11.7 Population under analysis 
The population analyzed in the study will consist of all patients included in the study as detailed in 
the protocol and without major deviations from the protocol. 
 
 
 
12.  Direct Access to Source Data/Documents 
The sponsor shall ensure that it is specified in the protocol or other written agreement that the 
investigator or institution shall allow direct access to the source data or documents for monitoring, 
auditing and review by the IRB as well as inspection of the trial by the competent health authorities. 
 
 
13.  Ethics 
General considerations: The test will be carried out in accordance with the principles emanating from 
the Declaration of Helsinki (See Annex VIII) and according to the legal regulations in force (Royal 
Decree 223/2004) and will not be started until the approval of the reference IRB has been obtained,
