Depot Medroxyprogesterone Acetate (DMPA), Rifampicin (RIF), and Efavirenz 
(EFV) in Women Co-Infected with Human Immunodeficiency Virus (HIV) and 
Tuberculosis (TB)” 
This clarification memo does not result in a change in the protocol informed consent 
document. The Division of AIDS does not require you to forward it to your institutional 
review board (IRB); however, as always, you must follow your IRB's policies and 

Clarification Memo #2

procedures. If IRB review of clarification memos is required at your site, please submit 
this document for review. 
Each site should file a copy of this clarification memo with the protocol for reference. 
The protocol clarifications contained in this memo should be implemented immediately. 
These updates will be included in the next version of the A5338 protocol if it is amended 
at a future date. 
The following are clarifications to A5338, Version 1.0, 12/12/14: 
The use of ethambutol (EMB) does not exclude a woman from participating in the study. This is 
supported by the following sections of the protocol: 

Inclusion criterion 4.1.4: Currently receiving RIF and Isoniazid (INH)-based TB therapy
on at least 5 days per week schedule after completion of the intensive phase of TB
treatment (minimum of 8 weeks of TB treatment) and expected to be on TB treatment for
a minimum of 12 weeks after enrollment.
This criterion does not exclude the use of EMB during the study.

Exclusion criterion 4.2.3: Use of any drugs other than RIF and EFV known to: 1) induce
CYP3A4 system within 30 days and to 2) inhibit the CYP3A4 system with one week prior
to study entry.
Because EMB does not induce or inhibit the CYP3A4 system, its use is consistent with
the language in the protocol.
Although the use of EMB is not prohibited, the sites are reminded to follow their country's TB 
treatment guidelines and to use EMB only if it is part of local standard of care for TB treatment. 
Sites should inform the team if other TB medications will be used in the study. All TB 
medications used in the study should be recorded on study case report forms (CRFs). 
Please contact the A5338 team at ACTG.COREA5338@fstrf.org with any questions.

Letter of Amendment #1 
          Page  2 of 4 
16 October 2015 
ACTG A5338 Protocol Version 1.0 
Upon receiving final IRB/EC and any other applicable regulatory entity approvals for this 
LOA, sites should implement the LOA immediately. Sites are still required to submit an 
LOA registration packet to the DAIDS Protocol Registration Office (PRO) at the Regulatory 
Support Center. Sites will receive a registration notification for the LOA once the DAIDS 
PRO verifies that all the required LOA registration documents have been received and are 
complete. An LOA registration notification from the DAIDS PRO is not required prior to 
implementing the LOA. A copy of the LOA registration notification along with this letter and 
any IRB/EC correspondence should be retained in the site’s regulatory files. 
The following are changes to A5338, Version 1.0, 12/12/14 (noted in strikethrough and bold 
font): 
1.
In the Exclusion Criteria (Section 4.2), the following changes are made:
a.
Section 4.2.1 is revised to:
Receipt of DMPA and or any other injectable contraceptive contraceptives within 
180 days prior to study entry.  
b.
Section 4.2.8 is revised to:
Any previous Breast breast cancer diagnosis. 
2.
In Pharmacy: Product Supply, Distribution, and Accountability (Section 5.3), the following
changes are made to allow sites the option to use locally available depot
medroxyprogesterone acetate (DMPA) instead of study-provided DMPA:
a.
The following paragraph is added as the 3rd paragraph in Section 5.3.1
Sites may use locally available DMPA if drug importation issues or delays are 
anticipated or encountered. The locally available DMPA must be approved by 
the A5338 Core Team before it can be used for the study. No additional funding 
will be provided to sites for purchasing DMPA locally, and participants and the 
participants' insurers must not be billed for the product. 
b.
Section 5.3.2
The site pharmacist is required to maintain complete records of all study products 
received from the NIAID CRPMC or any other source and subsequently dispensed. 
All unused study products must be returned to the NIAID CRPMC (or as otherwise 
directed by the sponsor) Study product not obtained from the CRPMC should be 
disposed of in accordance with the disposal standard operating procedures at 
the site after the study is completed or terminated. The site pharmacist at non-US 
Clinical Research Sites (CRSs) must follow the instructions in the manual Pharmacy 
Guidelines and Instructions for DAIDS Clinical Trials Networks in the section Study 
Product Management Responsibilities for the destruction of unused study 
products obtained from the CRPMC. 
3.
In the noncompliance criteria for premature study discontinuation (Section 8.1), the following
changes are made to clarify the criteria for missed doses and pharmacokinetic (PK)
sampling:

Letter of Amendment #1 
          Page  3 of 4 
16 October 2015 
ACTG A5338 Protocol Version 1.0 
a.
Section 8.1.3
Missed 2 or more of the RIF and/or EFV doses within one week prior to PK sampling 
at week 2, 4, 6, or 8 and did not return with acceptable adherence (ie, missed 2 or 
more of the RIF and/or EFV doses) for the rescheduled PK sampling for 2 
consecutive study weeks. 
b.
Section 8.1.4
Missed 2 or more of the RIF and/or EFV doses within one week prior to PK sampling 
at week 10 or 12 and did not return with acceptable adherence (ie, missed 2 or more 
of the RIF and/or EFV doses) for the rescheduled PK sampling. 
4.
In Section 9.5, the following changes are made to add review by an independent Study
Monitoring Committee (SMC) to the planned team monitoring:
The study team will monitor participant accrual to ensure the target number of evaluable 
participants is enrolled. Study sites will be required to report all participant dropouts and 
noncompliance, including missing PK sample times/visits to the study team as soon as 
they occur. The study team will make decisions on participant’s replacement on 
conference calls or by emails. The study team will also review data availability 
reports prepared by the study statisticians and/or laboratory data manager 
regularly, to ensure that samples for primary and secondary analyses are 
collected as anticipated. 
During the study, the safety and tolerability of the study medications will be monitored by 
means of adverse events reports representing laboratory and clinical data, such as 
Toxicity Summary reports or Phase I/II reports provided by ACTG DMC. It is required for 
study sites to enter these data into the DMC database within a specified time period for 
data entry. The study team will discuss these reports on regularly scheduled conference 
calls or by email. It is the responsibility of the study team to interpret the adverse event 
data and make any decisions needed to protect study participants from undue risk. Any 
concerns will be presented to the DAIDS Clinical Representative. 
An ACTG-appointed Study Monitoring Committee (SMC) review will take place at 
the earliest of (a) approximately 50% accrual to the study, (b) 6 months after 
enrollment of the first participant, or (c) if two or more participants become 
pregnant on study treatment.  Subsequent reviews will occur annually for as long 
as there are participants in follow-up. 
5.
In Pharmacology Study Design (Section 10.2), the following changes are made in the 1st and
2nd paragraphs to clarify the criterion for rescheduling a visit for PK sampling and the
schedule of the medroxyprogesterone acetate (MPA) PK and plasma progesterone
evaluations:
Doses of all ARV and TB medications taken for 48 hours prior to PK will be collected on 
the CRF at weeks 2, 4, 6, 8, 10, and 12. The participant should be contacted one week 
prior to the scheduled visit to reinforce the importance of 100% adherence to RIF and 
EFV and of her upcoming appointment. A participant who misses 2 or more doses of RIF 
and/or EFV within one week prior to the scheduled PK sampling at weeks 2, 4, 6, 8, 10, 
and 12 will have the visit rescheduled to one week later. For the week 10 and week 12 
visits, the rescheduled PK sampling should be strictly within the original visit window for 

Letter of Amendment #1 
          Page  4 of 4 
16 October 2015 
ACTG A5338 Protocol Version 1.0 
that visit. The schedule for the remaining visit weeks should not be changed. The rules 
for replacing participants who do not complete the PK are described in sections 8.1 and 
9.5.  
A single 4 mL blood sample for PK will be collected just prior to DMPA injection at week 
0 and at the scheduled visits at weeks 2, 4, 6, 8, 10, and 12. The blood sample will be 
centrifuged within 1 hour of collection to separate the plasma which will be stored at -
70°C or colder until assay for MPA and/or progesterone. 
6.
In the Sample Informed Consent (SIC), the following changes are made in the “Why Would
The Doctor Take Me Off This Study Early?” section to clarify the criteria for missed visits and
missed doses that would lead to premature study discontinuation:
a.
1st bullet
You miss two study visits in a row or you miss either the week 10 or week 12 visit. 
b.
2nd bullet
You do not take the RIF and/or EFV medications as you are supposed to and you 
then do not take the RIF and/or EFV prior to your rescheduled visit to collect the 
blood sample to measure the level of DMPA in your blood. 
The above information will be incorporated into the next protocol version as necessary if the 
protocol is amended.

HYPOTHESIS AND STUDY OBJECTIVES 
 
1.1 
Hypothesis 
 
Concurrent use of efavirenz (EFV) and rifampicin (RIF) will increase the clearance of 
medroxyprogesterone acetate (MPA) in HIV and TB coinfected women, resulting in 
reduced plasma MPA concentrations and reduced contraceptive efficacy. 
 
1.2 
Primary Objectives 
 
1.2.1 To estimate the optimal dosing frequency of depot MPA (DMPA) for HIV and TB 
coinfected women taking EFV-based combination antiretroviral therapy (cART) 
and RIF-containing TB treatment based on a target MPA concentration >0.1 
ng/mL. 
 
1.2.2 To determine whether a 150 mg DMPA IM injection will be adequate to suppress 
ovulation through 12 weeks in women taking EFV-based cART and RIF-
containing TB treatment based on serial plasma progesterone concentrations. 
 
1.3 
Secondary Objectives 
 
1.3.1. To estimate the area under the concentration-time curve (AUC), trough 
concentration (Cmin), maximum concentration (Cmax), apparent clearance (CL/F), 
and half-life (t1/2) of MPA in HIV and TB coinfected women taking EFV-based 
cART and RIF-containing TB treatment.  
 
1.3.2. To estimate time and variability in time to MPA Cmin reaching 0.1ng/mL or less in 
HIV and TB coinfected women taking EFV-based cART and RIF-containing TB 
treatment.   
 
1.3.3. To estimate the proportion of participants who maintain MPA levels above the 
minimum level thought to suppress ovulation (MPA 0.1ng/mL) through 12 weeks 
after DMPA administration. 
 
1.3.4. To evaluate the toxicity and safety of concurrent RIF, EFV, and DMPA use. 
 
1.4 
Exploratory Objectives 
 
1.4.1 To explore whether pharmacokinetic (PK) interactions between EFV, RIF, and/or 
DMPA are affected by human genetic polymorphisms that have been reported to 
affect metabolism of these drugs. 
 
1.4.2 To explore body mass index (BMI) and body fat content over time and correlate 
with DMPA levels. 
 
1.4.3 To explore relationship between DMPA and bone metabolism in the HIV and TB 
coinfected women.

INTRODUCTION 
 
2.1 
Background 
 
Tuberculosis (TB) remains the most common cause of morbidity in HIV-infected patients 
in resource-limited countries. In the pre-highly active antiretroviral therapy (HAART) era, 
patients with HIV with latent TB infection (LTBI) had about a 10% risk of developing TB 
disease annually, a proportion that is most important in areas of high TB prevalence. 
HIV, due to its ability to suppress the immune system, is a significant risk factor for 
development of active TB in patients with latent TB [1, 2]. The HIV epidemic has fueled 
the resurgence of the TB epidemic leading to a dramatic increase in TB infections in the 
resource limited countries [3]. HIV infection increases the risk for TB (acquisition, 
reactivation and reinfection), alters its clinical presentation, and reduces survival 
compared to patients with TB who are not HIV infected [4, 5]. A large percentage of 
patients on TB treatment will require combination antiretroviral therapy (cART).  
 
Globally, women comprise 52% of all people living with HIV. In Sub-Saharan Africa, 
women account for approximately 57% of all people living with HIV and the prevalence 
of HIV in women between the ages of 15 and 24 years remains more than twice as high 
as young men in the same age group [6, 7]. In settings of high HIV prevalence, young 
women aged 15 to 24 years experience tuberculosis rates 1.5 to 2 times higher than 
men in the same age group [7]. Decisions about contraception in a population of women 
infected with both TB and HIV are of paramount importance. In the setting of the 
treatment of active tuberculosis, preventing pregnancy becomes even more important 
because it allows women to attain a level of health that will support healthy future 
pregnancies. Treatment options for TB may be limited in pregnancy because of 
concerns about teratogenicity. Indeed, fetal exposure to RIF, although generally 
considered safe, is associated with bleeding disorders. Treatment of TB before 
pregnancy avoids TB exposure in the neonate, a condition associated with high infant 
mortality. 
 
Millions of women around the world use DMPA (Depo-Provera), an intermediate-acting 
progesterone-only injectable contraceptive, for prevention of pregnancy because of its 
high efficacy rate and its ease and convenience of administration [8]. According to data 
from the United Nations (UN) and Africa, more than 50% of women choosing reversible 
contraception in Sub-Saharan Africa use DMPA. Unfortunately DMPA’s safety and 
effectiveness among women coinfected with TB and HIV is unknown since the 
interactions of TB treatment, cART, and DMPA have not been well studied. A 
pharmacological interaction between hormonal contraceptives and RIF was described in 
the 1970s, and unintended pregnancies reported, leading to national guidelines 
recommending alternative dosing schedules for DMPA without good evidence for these 
recommendations [9]. The requirement for a third drug (EFV) with potential interactions 
makes the contraceptive efficacy of DMPA even more difficult to predict. 
 
While some studies suggest that women using progestin-only injectable contraceptive 
may be at increased risk of transmitting HIV to an uninfected partner, most other studies 
have not shown this association except for a recent observational study which 
suggested a relationship between the use of DMPA and HIV transmission to an

uninfected partner [10]. Further work indicated that this might be due to increased genital 
tract viral load in women using this method of contraception [11]. A pigtail macaque 
model looking at the effect of DMPA on simian HIV (SHIV) showed no increase in 
plasma viral load or vaginal shedding of SHIV [12] and a recent prospective study did 
not find an association between DMPA and cervical HIV in well-suppressed women on 
ART [13]. Several studies are underway that will elucidate the relationship between 
contraceptive method choice and infectivity (Clinical Trial on the Effects of Progestin-
based Contraception in the Genital Tract of HIV-infected and Uninfected Women, 
[NCT02103660] and HIV-Target Cell Response in Women Initiating Various 
Contraceptive Methods in High HIV-Incidence Areas: Zim CHIC [NCT02038335]). A 
World Health Organization (WHO) expert group reviewed all available evidence and 
recommended that women at high risk for HIV infection and women living with HIV can 
continue to use all existing hormonal contraceptive methods including DMPA without 
restriction. Women using progesterone-only injectable contraceptive should also be 
advised to use condoms as an HIV preventive measure [14]. 
 
2.1.1 DMPA 
 
Medroxyprogesterone acetate (MPA, Provera) is a 21-carbon synthetic progestin 
with high selectivity and activity resembling those of natural progesterone. MPA 
has been used extensively in combination with estrogens for oral hormone 
replacement therapy in postmenopausal women. Relative to progesterone, MPA 
undergoes substantially less first-pass hepatic metabolism when given orally. 
MPA has a plasma half-life of 24 hours, with hepatic metabolism to various polar 
compounds and their conjugates [1]. DMPA, given as a 150 mg intramuscular 
dose, inhibits ovulation for up to 14 weeks and is therefore, given every 3 months 
to ensure continuous contraception, with a typical use failure rate of 0.3% during 
the first year [15]. The apparent half-life of DMPA is approximately 50 days after 
the intramuscular (IM) injection. Peak plasma concentration (1 to 7 ng/mL) is 
reached within 3 weeks of the injection and decreases exponentially to become 
undetectable at 120 to 200 days after dosing. MPA levels stay above the 
concentration needed to suppress ovulation (0.1 ng/mL) for approximately 3 
months [16, 17, 18]. MPA levels at 3 months (12 weeks, Cmin) after injection 
ranges from 0.04 to 1.31 ng/mL and mean MPA Cmin is 0.45 ng/mL with 
coefficient of variation (CV) of 53% when coadministered with NRTIs only and 
0.37 ng/mL with CV of 57% when co-administered with EFV-containing regimen. 
Women may not ovulate for up to 6 months after the last DMPA dosing [19]. 
 
DMPA prevents conception by inhibiting gonadotropin release, leading to 
ovulation suppression and thinning of the endometrial lining. Luteal activity and 
ovulation, as indicated by a rise in serum progesterone to >5 ng/mL, occurs when 
the MPA concentration drops to <0.1 ng/mL [17, 20, 21]. 
 
DMPA is metabolized via the cytochrome p450 enzyme system [16] and induces 
the activity of CYP3A4. When given as an injectable, MPA induces activity of 
CYP3A4 by 25% [18]. PK studies of DMPA with selected antiretroviral agents 
have not demonstrated a reduced contraceptive efficacy as assessed through 
ovulation suppression measured by progesterone levels [16, 19]. Non-NRTIs 

 
15 
A5338 
Final Version 1.0 
 
 
12/12/14 
 
(NNRTIs) and protease inhibitors (PIs) have demonstrated significant interactions 
with combined oral contraceptives (COC), which might lead to decreased efficacy 
of the COC [22, 23]. Studies of interactions between ART and DMPA have not 
demonstrated any clinically significant changes in the levels of either selected 
cARTs or DMPA. Cohn et al. showed that there were similar levels of DMPA in 
women on selected cART regimens (nelfinavir [NFV], nevirapine [NVP] and EFV) 
compared to women not on cART [16, 24]. Another small study done recently 
also failed to show significant changes in the PK of DMPA in HIV-infected women 
on cART with zidovudine (ZDV), lamivudine (3TC), and EFV [19]. This cART 
combination did not increase DMPA-related adverse events nor did it decrease 
the effectiveness of DMPA [19]. DMPA has not been shown to significantly alter 
the levels of antiretroviral drugs.  The levels of EFV remained unchanged 
compared to baseline in the Cohn et al. study [16]. Current guidelines do not 
recommend changes in dosing frequency for patients on EFV-containing cART 
who use DMPA.   
 
It is unknown whether simultaneous treatment of HIV and TB affected the serum 
concentration, efficacy, or adverse effects (AEs) of DMPA. 
 
There have been concerns about decreased effectiveness of DMPA in obese 
women.  No pregnancies were documented in two large phase 3 trials that 
included 193 women (of 1787 total) with a body mass index (BMI) of >30 [25]. A 
detailed study designed to assess the efficacy of DMPA in obese women 
revealed fluctuating estrogen levels consistent with follicular development, but no 
evidence of ovulation [26]. Patients being treated for both TB and HIV may 
experience even more variability in estrogen and DMPA levels. Patients treated 
for TB typically gain weight. The proportion of fat gain in that setting is variable 
and may affect DMPA metabolism. In the exploratory objective, BMI and body fat 
content will be estimated over time and compared to DMPA levels.   
 
Safety Profile:  
 
DMPA is safe in HIV infected women. There were few toxicities in the ACTG 
A5093 study related to DMPA with abnormal menstrual bleeding being the most 
frequent and similar to non-HIV-infected populations [16, 24]. Watts et al. 
demonstrated no significant changes in the levels of circulating HIV viral load in 
patients after administration of DMPA [24].  
 
The most common side effects are menstrual irregularities (bleeding or spotting), 
amenorrhoea (2.1%) abdominal pain/discomfort 11%, weight gain (37.7%), 
dizziness 6%, headache 17%, nervousness 11%, and decreased libido 6%. 
 
DMPA users were found to gain more weight than users of other forms of 
hormonal contraceptives with a >10% weight gain demonstrated in some 
populations [27]. A prospective cohort found that after 18 months of use women 
with a BMI ≥30 had a significantly higher mean weight increase (9.45 kg) 
compared to women with a BMI <25 (4.04 kg). A baseline assessment of BMI 
may predict weight gain expected with DMPA use [28].

Other less common adverse reactions include loss of bone mineral density, 
thromboembolic disorders, insomnia, depression, acne, breast pain, and 
arthralgia. 
 
2.1.2 Rifampicin (RIF): 
 
Rifampicin is a semi-synthetic rifamycin derivative that is highly active against 
mycobacteria, most gram-positive bacteria, and some gram-negative bacteria. It 
is bactericidal for both intracellular and extracellular microorganisms. By 
inhibiting prokaryotic DNA-dependent RNA polymerase, it suppresses the early 
elongation of the nucleotide chain in RNA synthesis. It is a key component of TB 
treatment and RIF containing regimens are associated with reduced mortality 
compared to non RIF containing regimens. Studies have demonstrated that 
addition of RIF to a TB regimen shortens the duration of treatment with higher 
cure rates [29]. Menzies et al. demonstrated that regimens that contained RIF for 
only 1-2 months of TB treatment instead of 6 months had high failure rates with 
an increased chance of relapse and resistance development [30].  
  
An oral dose of RIF is absorbed completely when taken on an empty stomach, 
and after 1.5 to 2 hours, a 600 mg dose yields a peak blood level of 8 to 20 
mcg/mL. The half-life of RIF varies from 2 to 5 hours, and it is shortened by 
approximately 20 to 40% after the first week of daily treatment because of RIF’s 
auto-induction of hepatic microsomal enzymes. The half-life is unaffected by 
renal impairment but is increased by liver disease or biliary obstruction. RIF is 
deacetylated to an enterohepatically recirculated active metabolite, and 50% to 
60% is excreted in the feces. Up to 30% of a dose is excreted in the urine. 
Approximately 85% of circulating RIF is bound to plasma proteins, and is widely 
distributed throughout the body. Certain genetic polymorphisms have been 
associated with reduced concentrations of rifamycin antibiotics, including RIF 
[31].   
 
RIF is a potent inducer of multiple cytochrome P450 enzymes, such as CYP3A 
and CYP2B6, and drug transporters can accelerate clearance of drugs 
metabolized via the cytochrome p450 system, including cART [18, 19, 22] with 
potential loss of efficacy of these drugs.  
 
RIF reduces the concentrations of many antiretroviral medications, especially PIs 
like atazanavir (ATV) and lopinavir/ritonavir (LPV/r) [32], and NNRTIs like NVP. 
The effect of RIF on EFV concentrations appears to depend on the CYP2B6 
metabolizer genotype of the patient. CYP2B6 genotype not only determines the 
plasma EFV concentration at a given time point but also the long-term effects of 
EFV auto-induction on plasma exposure. Individuals with the extensive-
metabolizer phenotype tend to have a pronounced EFV auto-induction effect, 
which has influence on the long-term therapeutic outcome [33]. In patients 
coinfected with TB and HIV, EFV-metabolizing enzymes are induced maximally 
during the first 4 weeks of RIF’s use and EFV therapy does not induce the 
enzymes to any greater extent. This suggests that EFV has no significant 
additive or synergistic enzyme induction effect with on-going RIF therapy in 

 
17 
A5338 
Final Version 1.0 
 
 
12/12/14 
 
HIV/TB co-treated patients. That is to say, the duration of therapy influences 
long-term EFV auto-induction in the absence of RIF; however, in the presence of 
RIF, maximal induction occurs during the early stages of therapy, and prolonged 
EFV dosing does not further reduce EFV concentrations in these auto-inducers 
[34]. A study done in South Africa found no evidence of a decrease in EFV mid-
dosing interval plasma concentration in the presence of RIF, and a high 
proportion of South Africans were found to have the CYP2B6 polymorphism 
which impairs metabolism of EFV [35]. Similar results were demonstrated in a 
study in South India which concluded that RIF did not significantly alter the 
steady-state PK of EFV in HIV-infected patients [35, 36]. Globally, among HIV-
infected patients who require RIF-containing TB therapy, EFV-based cART is the 
preferred HIV regimen. 
 
Safety Profile:  
 
In the usual daily dose of 10 mg/kg (maximum 600 mg), RIF is well tolerated. It 
often causes harmless red-orange discoloration of tears, sweat, saliva, feces, 
and urine. Less than 4% of TB patients experience significant adverse reactions 
to RIF. Gastrointestinal AEs are the most common, and they include epigastric 
distress, anorexia, nausea, vomiting, cramps, and diarrhea. Hepatitis rarely 
occurs in persons who have normal baseline hepatic function. The incidence of 
hepatitis may be increased for older persons and those who have chronic liver 
disease or alcoholism, but remains substantially lower than that for pyrazinamide 
or isoniazid. RIF can cause a flu-like syndrome of fever, chills, and myalgia (felt 
to be related to the development of antirifampicin antibodies), although this is 
uncommon using the 600 mg dose given daily or thrice-weekly. In a very small 
proportion of patients the flu-like syndrome is associated with interstitial nephritis, 
acute tubular necrosis, thrombocytopenia, hemolytic anemia, and shock.  There 
may be changes in menstruation like oligomenorrhoea and amenorrhea [37]. 
 
2.1.3 Efavirenz (EFV): 
 
EFV is a potent NNRTI that is widely used in combination with other ARVs for the 
treatment of HIV-1 infection. Studies support its use for initial therapy.  
 
The single dose of the 600 mg EFV tablet administered to patients after a high-
fat/high-calorie meal and while fasting was generally well tolerated. Even though 
the US FDA approved a revised label for EFV stating that the dose should be 
increased to 800 mg daily in patients also taking rifampin who weigh over 50 kg, 
the CDC recommends use of the standard 600 mg dose of EFV in patients being 
cotreated for TB regardless of their weight. The evidence for use of a higher dose 
of EFV in this clinical scenario is inconclusive, and the higher EFV dose has 
been associated with an increased incidence of neurotoxic side effects. There is 
large inter-individual variability in EFV metabolism, such that universally 
increasing the EFV dose in participants weighing over 50 kg may increase the 
incidence of EFV-related AEs.

Steady-state plasma EFV clearance is known to be affected by relatively frequent 
genetic polymorphisms, primarily in CYP2B6 (esp. rs3745274 and rs28399499) 
[38, 39, 40, 41, 42], and perhaps also in CYP2A6 [43]. Genotyping of CYP2B6 
can be used to characterize individuals as belonging to slow, intermediate, and 
extensive EFV metabolizer groups. Metabolites of EFV lack anti-HIV activity. 
 
Safety Profile:  
 
The most significant AEs observed in patients receiving EFV were central 
nervous system (CNS) symptoms, psychiatric symptoms, and rash [44]. Fifty-
three percent of individuals noted CNS complaints, which may include dizziness, 
insomnia, impaired concentration, somnolence, abnormal dreaming, euphoria, 
depression, confusion, agitation, amnesia, hallucinations, stupor, abnormal 
thinking, and depersonalization. In addition, convulsions have been observed in 
the presence of known medical history of seizures. CNS symptoms usually begin 
during the first 1 or 2 days of therapy and generally resolve after the first 2 to 4 
weeks. Dosing at bedtime improves the tolerability of these symptoms and is 
recommended during the first weeks of therapy and in patients who continue to 
experience these symptoms.  
 
Serious psychiatric adverse experiences have been reported, including severe 
depression, suicidal ideation or attempts, aggressive behavior, paranoid 
reactions, and manic reactions. Rash is usually mild to moderate and occurs 
within the first 2 weeks of initiating therapy. In most persons, rash resolves with 
continuing EFV therapy within 1 month. EFV can be reinitiated in persons 
interrupting therapy because of rash. 
 
There is concern for potential teratogenic effects with EFV exposure in the first 
trimester of pregnancy. An increased incidence of neural tube defects has been 
observed in fetuses from EFV-treated monkeys that received doses resulting in 
plasma drug concentrations similar to those in humans given 600mg/day. There 
are also case reports of neural tube defects linked to first trimester EFV exposure 
in humans. Therefore, pregnancy should be avoided in women receiving EFV, 
and barrier contraceptives should always be used in combination with hormonal 
contraceptives to maximize pregnancy prevention.   
 
Most new-onset AEs were reported as mild and transient. A greater percentage 
of patients who received EFV under fed conditions (91.3%) reported AEs 
compared with patients who received EFV under fasted conditions (73.9%). 
Patients who received EFV after the meal also reported individual AEs more 
frequently. The AEs that were reported by >10% of patients under fed conditions 
included dizziness (16, 69.6%), headache (7, 30.4%), impaired concentration (6, 
26.1%), and nausea (3, 13%). The AEs that were reported by >10% of 
participants under fasted conditions included dizziness (10, 43.5%, headache (4, 
17.4%), and impaired concentration (4, 17.4%). Two (10%) patients each 
reported an AE of moderate intensity that was considered to be of possible 
(headache, fasted) or probable (abdominal pain, fed) relationship to study 
medication. There were no serious AEs or deaths reported. No clinical laboratory

results were reported as AEs by the investigator.  No one discontinued the study 
because of an AE. 
 
It is recommended that EFV be taken on an empty stomach, preferably at 
bedtime. For more information concerning EFV, refer to the most recent package 
insert. 
 
2.2 
Rationale 
 
The high burden of TB in HIV-infected women, the increased prevalence of HIV in 
women of reproductive age, and the limited data on use of DMPA in women being 
treated simultaneously for TB and HIV make it crucially important to understand the 
clinical significance of interactions among DMPA, EFV, and RIF given the significant 
number of women who could benefit from this combination of medications [45]. It is not 
known whether patients taking RIF and EFV together eliminate MPA faster than women 
taking DMPA alone. This needs to be evaluated to determine the optimal frequency of 
DMPA injections in HIV/TB co-infected patients. 
 
Given that women of reproductive potential are overrepresented in the population of 
HIV/TB coinfected individuals and given the risk to the mother and fetus if pregnancy 
occurs during co-treatment of these infections, reliable contraception for this population 
of women is especially important. While it has been shown that RIF reduces the levels of 
both oral estrogen and progesterone [46, 47], its effect on injectable progestin has not 
been clearly characterized. Because MPA is extensively metabolized in the liver, largely 
by CYP3A, it is likely that RIF will reduce MPA concentrations when DMPA and RIF are 
coadministered [15]. Some country guidelines, including the 2004 South African 
guidelines, have recommended shortening the dosing interval of DMPA from 12 weeks 
to 8 weeks in patients concurrently taking RIF [48]. Even though these guidelines were 
revised in December 2012 to recommend use of DMPA with the 12-week dosing interval 
in patients on rifampicin, there has been no new data on the effectiveness of DMPA in 
these patients. Australian Centre for Disease Control (CDC) guidelines for control of 
Tuberculosis in the Northern Territory recommend use of methods of contraception in 
patients on RIF other than DMPA and COC [49]. Some country guidelines, however, 
recommend use of DMPA keeping the 12-week dosing interval, even though the effects 
on pregnancy risk are unknown in patients coinfected with TB. The WHO document, 
Medical Eligibility Criteria for Contraceptive Use, recommends use of DMPA but advises 
medical followup by the provider [50]. However, there are still limited data on whether 
RIF has a negative impact on the effectiveness of DMPA [51], even when DMPA is given 
more frequently, and the optimal dosing frequency for DMPA has not been established 
in this population. This study, therefore, will focus on the effects of combined RIF-
containing TB treatment and EFV-based cART on DMPA. 
 
DMPA suppresses the pituitary-ovarian-uterine axis and consequently may result in a 
hypoestrogen state which may lead to bone resorption exceeding bone formation 
resulting in reduced bone mineral density especially in adolescence and early adulthood 
before full bone maturity is attained. This loss in bone mineral density is unlikely to 
happen in the first 12 weeks and appears to be the greatest in the first 2 years of use 
and plateaus thereafter. [52, 53] In 2004, the FDA issued a black box warning that the 

 
20 
A5338 
Final Version 1.0 
 
 
12/12/14 
 
reduced mineral density may not be completely irreversible and its effect in increased 
risk of osteoporotic bone fractures later in life is unknown [54]. Currently, bone mass 
measurement heavily relies on x-ray like DEXA scan which are expensive and not easily 
accessible in resource limited settings. Development of future assays for biomarkers of 
bone metabolism for early detection of reduced bone mass will be very useful. The 
mechanism for the bone loss has not been extensively studied, with very little data in 
HIV-infected women. Because of this, blood for bone biomarkers will be collected before 
and 12 weeks after receiving DMPA and future funding for analyses of these specimens 
will be sought. Of particular interest is the potential additive toxicity of tenofovir disoproxil 
fumarate (TDF)-containing regimens and other agents that increase bone resorption.  
This study is not powered to assess this interaction, but evaluation of the cART 
regimens may lead to the detection of a signal warranting further study. 
  
This study will enroll women with known TB infection during the continuation phase of 
RIF-containing TB treatment regimen who are on a stable cART regimen consisting of at 
least 2 NRTIs and EFV. Women will be given DMPA after being on EFV-based cART for 
at least 4 weeks and on RIF-containing TB treatment for at least 8 weeks. PK 
assessments for MPA will be assessed pre-dose then every 2 weeks after starting 
DMPA administration, through week 12. The rationale for giving DMPA at this time point 
is: (1) RIF and EFV concentrations are near steady state and maximal induction effect 
will be achieved; and (2) RIF dosing frequency does not change during the continuation 
phase of TB treatment (whereas frequency and concurrent TB drugs may change 
between the intensive and the continuation phases). Initiating the study treatment within 
the four weeks after completion of intensive phase TB treatment allows a 12-week 
period required for completion of the study. 
 
The results of this study are likely to be applicable to patients receiving RIF-containing 
TB treatment that are not being treated concurrently with EFV as well, given that addition 
of EFV to RIF is unlikely to increase induction of metabolizing enzymes significantly 
beyond the induction achieved with RIF alone. 
 
 
3.0 
STUDY DESIGN 
 
A5338 is an open-label, non-randomized 12-week, single-arm study to determine the PK 
of single-dose DMPA among women with TB and HIV co-infection who are receiving 
RIF-containing TB treatment plus EFV-based cART. Biomarkers of suppression of 
ovulation will also be evaluated. Participants will be HIV and TB co-infected women who 
have completed the intensive phase and are already in the continuation phase of RIF-
containing TB treatment and who have been on EFV-based cART for at least 4 weeks. 
 
Women diagnosed with TB and who are not already receiving HIV treatment at the time 
of screening for eligibility may start cART at any time between 2 and 8 weeks after TB 
treatment has been initiated, at the discretion of the treating physician and health care 
provider at the local clinic and in accordance with national and local treatment 
guidelines. Women who develop TB while on ART may also participate in the study. At 
study entry, all participants will receive a single IM injection of DMPA.

We will estimate individual MPA elimination rates, and then examine if any participant 
has a plasma progesterone level >5 ng/mL by the time that the estimated MPA level 
reaches 0.1 ng/mL. If data allows, a correlation between plasma progesterone levels and 
MPA concentrations observed at study weeks 10 and 12 will be investigated to better 
understand a minimum threshold of MPA concentration level to prevent ovulation using 
plasma progesterone level. If MPA clearance is induced by the co-administered drugs, 
the study week 10 and later are thought to be the times when ovulation would be most 
likely to occur, and increased plasma progesterone levels would be seen.   
 
We will estimate MPA area under the concentration-time curve (AUC) by collecting PK 
samples from baseline (week 0) pre-DMPA dosing through week 12 after DMPA dosing 
from all participants. We will determine whether potential PK interactions between EFV-
based cART with RIF and DMPA affect the suppression of ovulation as measured by the 
proportion of participants whose progesterone level is >5 ng/mL at weeks 2, 4, 6, 8, 10, 
and 12. We will also determine the proportion of women who have sub-therapeutic 
concentrations of MPA (levels <0.1 ng/mL) at different time points. Using a combination 
of both sub-therapeutic concentrations of MPA and progesterone >5 ng/mL, we will be 
able to determine whether contraception is thought to be maintained throughout the 12-
week study. Mathematical modeling will be employed to determine the optimal frequency 
of DMPA dosing in the setting of TB and HIV cotreatment. 
 
Information about demographic factors that can affect drug concentrations such as age, 
sex, ethnicity, disease state, and concomitant drug use will be collected on all 
participants. Whole blood will be collected and stored for potential pharmacogenomics 
analyses including CYP2B6 genotyping. All participants will be strongly encouraged to 
use condoms and non-hormonal contraceptives for prevention of pregnancy and 
sexually transmitted infections (STI) if engaging in behaviors that put them at risk. The 
participants will be informed that the contraceptive effect of DMPA may be attenuated 
and participants who engage in activities that could lead to pregnancy will be required to 
use another non-hormonal contraceptive. Other forms of hormonal contraceptives will be 
prohibited. Women who have had a tubal ligation or other sterilization procedure, are 
currently using a non-hormonal intrauterine device (IUD) or those whose partners have 
had a vasectomy will be eligible for the study. 
 
All participants will complete self-reported questionnaires to assess adherence to both 
TB therapy and cART, and to collect AEs commonly reported with DMPA, ie, irregular 
bleeding patterns. Adherence will also be assessed by review of patients’ TB treatment 
records and participant’s self-report.

other than the initial rapid HIV and/or E/CIA, or by HIV-1 antigen, plasma HIV-1 
RNA viral load. 
 
NOTE: The term “licensed” refers to a US FDA-approved kit, which is required for 
all IND studies, or for sites located in countries other than the United States, a kit 
that has been certified or licensed by an oversight body within that country and 
validated internally. Non-US sites are encouraged to use US FDA-approved 
methods for IND studies.  
 
WHO and CDC (Centers for Disease Control and Prevention) guidelines 
mandate that confirmation of the initial test result must use a test that is different 
from the one used for the initial assessment. A reactive initial rapid test should be 
confirmed by either another type of rapid assay or an E/CIA that is based on a 
different antigen preparation and/or different test principle (eg, indirect versus 
competitive), or a Western blot or a plasma HIV-1 RNA viral load. 
 
4.1.2 Current tuberculosis infection, confirmed or probable diagnosis. 
 
Confirmed TB is defined as:

aspirate, cerebrospinal fluid or blood. 
 
Probable TB is based on the clinician’s judgment where acid-fast bacilli are not 
demonstrable but sufficient clinical suspicion exists to initiate empiric TB therapy. 
A probable diagnosis may be based on the presenting clinical symptoms of fever 
for more than 2 weeks, unintentional weight loss of more than 10% of body 
weight, night sweats, positive TB contacts, radiographic findings, and the 
absence of another possible diagnosis.

6.2 
Timing of Evaluations 
 
6.2.1 Screening Evaluations  
 
Screening evaluations must occur prior to the participant’s starting any study 
medications, treatments, or interventions. At the time of screening, participants 
must have completed the intensive phase and be in the continuation phase of TB 
treatment. Participants must require at least 12 more weeks of TB treatment at 
the time they receive the DMPA injection at study entry. 
 
Site staff are encouraged to contact/liaise with primary care physicians at TB 
clinics for identification of eligible participants prior to completion of the intensive 
phase of TB treatment. Information about the location of the ARV clinic and 
planned timing of cART initiation should be obtained. The identified participants 
will be given appointments for the research clinic as soon as they are initiated on 
cART. Site staff will obtain contact details of these potential participants to 
remind them about scheduled screening appointments. Eligible participants will 
be enrolled as soon as eligibility is determined. 
 
Screening evaluations to determine eligibility must be completed within 30 days 
prior to study entry unless otherwise specified. In addition to data being collected 
on participants who enroll into the study, demographic, clinical, and laboratory 
data on screening failures will be captured in a Screening Failure Results form 
and entered into the ACTG database.  
 
6.2.2 Entry Evaluations 
 
Entry evaluations must be completed on the day of registration after eligibility is 
determined from the screening evaluations. Participant must begin treatment the 
same day of registration. Entry evaluations must be completed prior to DMPA 
administration. 
 
Enrollment and completion of entry evaluations after the start of the monthly 
menstrual flow is preferred. 
 
6.2.3 
Post-Entry Evaluations 
 
Post-entry evaluations occur after study entry and injection of DMPA. Study visits 
are scheduled as indicated in the Schedule of Events (SOE) in section 6.1. The 
final visit is the week 12 visit. 
 
The visit windows for post-entry evaluations are ±3 days for weeks 2, 4, 6, and 8, 
and ±7 days for weeks 10 and 12. The evaluations at weeks 10 and 12 should be 
performed as close as possible to the ideal visit date.  If the week 10 or week 12 
PK sampling is rescheduled, the reschedule date must be within the original visit 
window for the visit. There must be at least 3 days between the PK samples 
collected at each visit.

CLINICAL MANAGEMENT ISSUES 
 
7.1 
Toxicity  
 
Toxicities will be evaluated and managed by the study team in close consultation with 
the participants’ primary care clinicians. Ongoing communication between the ACTG 
study staff and the participants’ clinicians will be encouraged. If either the study team or 
primary care clinician becomes aware of an adverse event, he/she will contact the other 
within 24 hours of awareness. 
 
For participants who experience toxicities that require treatment interruption or changes, 
a detailed letter with the results will be sent to primary care physicians by the study staff 
informing them about the toxicities and planned management from the study 
perspective.  
 
If TB medication or cART is held for toxicity by the primary care physician, participants 
must inform the study team. Information about these treatment modification/ 
interruptions must be recorded on the source document and CRF.  
 
Grades 1 and 2: can be managed as per standard of care by the study doctor. 
  
Vaginal Bleeding: ≥Grade 2 must be closely monitored and managed as per standard of 
care. 
 
Grades 3 and 4: participants must be stabilized and referred immediately if required to 
obtain treatment at local hospital.  
 
7.2 
Pregnancy  
 
If a participant becomes pregnant on study, she will continue to be followed on study and 
on cART and TB treatment, and have the study evaluations performed following the visit 
schedule in section 6.1, except the PK evaluation, until she completes the study.  After 
she completes the study, she will be followed for safety until the outcome of her 
pregnancy is known.  
 
If a woman has completed the study or chooses to discontinue from the study before the 
end of the pregnancy, then site staff should request permission to contact her regarding 
pregnancy outcomes at the end of pregnancy. If the information is obtained, pregnancy 
outcomes will be submitted on a CRF at the end of the pregnancy.  
 
Pregnancy Outcomes and Reporting 
A Pregnancy Outcomes CRF should be completed for all participants who become 
pregnant. The intrapartum complications and/or pregnancy outcome should be recorded 
on the CRFs.  
 
Sites are encouraged to report prospectively any pregnancy to The Antiretroviral 
Pregnancy Registry if such occurs during this study. More information is available at 
www.apregistry.com; Fax: 44-1628-789-666 or 910-256-0637; Phone: 910-679-1598.

8.1.2 Failure by the participant to attend any of the week 10 or week 12 visit. 
 
8.1.3 Missed 2 or more of the RIF and EFV doses within one week prior to PK 
sampling at week 2, 4, 6, or 8 and did not return with acceptable adherence (ie, 
missed 2 or more of the RIF and EFV doses) for the rescheduled PK sampling 
for 2 consecutive study weeks. 
 
8.1.4 Missed 2 or more of the RIF and EFV doses within one week prior to PK 
sampling at week 10 or 12 and did not return with acceptable adherence (ie, 
missed 2 or more of the RIF and EFV doses) for the rescheduled PK sampling. 
 
NOTE: A participant who prematurely discontinues from the study due to noncompliance 
will be replaced. 
 
8.2 
Participant requires a change in the cART or TB regimen during the 12 weeks on study. 
 
8.2.1 For the purposes of this study, a cART change that will warrant replacement of 
the participant includes:

STATISTICAL CONSIDERATIONS  
 
9.1 
General Design Issues 
 
This is a phase II, open-label, single arm, PK study to investigate effects of 
coadministered EFV and RIF on PK of DMPA  in HIV- and TB-coinfected women and to 
evaluate whether the current dosing frequency of DMPA is adequate to suppress 
ovulation in women when taken together with an EFV- and RIF-containing regimen. 
 
A woman is eligible for this study if she is premenopausal between the ages of 18 and 
46 and co-infected with HIV and TB.  Women must be on both RIF (600 mg once daily)-
containing TB treatment and EFV (600 mg once daily)-based cART at least 4 weeks 
before study entry. 
 
After HIV- and TB-coinfected women undergo screening evaluations for study eligibility, 
PK samples for MPA concentrations from eligible women will be taken at study entry. 
After entry, PK samples for MPA concentrations will be taken every 2 weeks during the 
12-week study period. Blood samples for plasma progesterone levels will be collected 
from all the eligible women for investigating evidence of ovulation during the 12 weeks of 
DMPA administration. 
 
Eligible women will also undergo study visits for safety labs at weeks 4 and 12.  Signs 
and symptoms will be assessed at bi-weekly study visits. 
 
9.2 
Outcome Measures 
 
9.2.1 Primary Outcome Measures 
 
MPA concentration levels obtained at 2, 4, 6, 8, 10, and 12 weeks after DMPA is 
administered. The 12 week measurement will be the measurement obtained 
closest to 84 days after DMPA is administered. The allowable window for the 
measurement is ±7 days, as stated in section 6.2.3. 
 
Plasma progesterone levels obtained at 2, 4, 6, 8, 10, and 12 weeks after DMPA 
is administered.

9.2.2 Secondary Outcome Measures 
 
9.2.2.1 Estimation of MPA PK parameters in HIV and TB co-infected women 
taking EFV and RIF: 
MPA PK parameters AUC over the 12 weeks (AUC0-12wk), Cmin, Cmax, 
apparent clearance (CL/F), and half-life (t1/2) calculated using standard 
non-compartmental method: These PK parameters will be calculated 
based on the MPA concentrations obtained every 2 weeks over the 12 
weeks. MPA concentration obtained at entry (prior to DMPA 
administration) will be evaluated as confirmation that no DMPA was 
taken prior to study entry.   
 
9.2.2.2    Estimation of time and variability in time to reach MPA 0.1 ng/mL: 
Times (weeks) where elimination slopes estimated fitting loge-linear 
regression models to the individual MPA concentrations obtained in the 
elimination phase reach MPA level of 0.1 ng/mL: The exact sampling 
time (weeks) will be used. 
 
9.2.2.3    Estimation of the proportion of participants reaching MPA level <0.1 
ng/mL at specified time points: 
MPA concentration levels obtained at study weeks 6, 8, and 10. Since 
the week 12 measurements will be evaluated as the primary outcomes 
(section 9.2.1), the MPA measurements at study weeks 6, 8, and 10 
after DMPA administration will be studied for any earlier sign of MPA 
levels <0.1 ng/mL.   
 
9.2.2.4    Evaluation of toxicity and safety: 
All adverse events with toxicity Grade ≥3 from signs/symptoms and 
chemistry and hematology laboratory analyses. 
 
9.2.3 Exploratory Outcome Measures 
 
9.2.3.1 Human genetic variants/polymorphisms that are known to affect PK of 
EFV (eg, CYP2B6) and RIF (eg, SLCO1B1). 
 
9.2.3.2 Participants’ BMIs and body fat percentages collected over the study 
period of 12 weeks. Body fat percentages will be estimated using age, 
body weight, height, and waist circumference. 
 
9.3 
Randomization and Stratification 
 
Since this study has a single study arm, no randomization will be employed. There will 
be no stratification for participants.

9.4 
Sample Size and Accrual 
 
It is known that DMPA, EFV, and RIF drugs share some common metabolic pathways 
via the CYP3A4 enzyme system: MPA is metabolized by and induces CYP3A4 activity; 
RIF is primarily metabolized by CYP2B6 system but also by CYP3A4 and induces 
CYP3A4 and CYP2B6 enzyme activities; EFV is primarily metabolized by CYP2B6 and 
both induces and inhibits CYP3A4 enzyme activity (mixed and unpredictable activity). 
Therefore, it is anticipated that co-administration with EFV and RIF will induce clearance 
of MPA concentration, resulting in lower MPA concentrations during the elimination 
phase, compared to those seen when DMPA is administered alone. Thus, DMPA may 
need to be administered more frequently when used together with EFV and RIF.   
 
The study hypothesis is that concurrent use of EFV and RIF increases the clearance of 
MPA, resulting in reduced MPA concentrations. The study will evaluate whether more 
frequent DMPA dosing is needed when DMPA is administered in combination with EFV 
and RIF in HIV- and TB-infected women. The evaluation of dosing frequency will be 
conducted by estimating the proportion of women with MPA levels <0.1 ng/mL 12 weeks 
post-dose (at the end of the dosing cycle). The critical value 0.1 ng/mL for MPA levels 
was chosen based on published papers including studies by Mishell [17] and Smit et al. 
[55]. These studies indicate that when MPA level falls below 0.1 ng/mL, serum 
progesterone level rises and the probability of ovulation increases. 
 
In ACTG DMPA studies A5093 and A5283 in HIV-infected women, of the 79 PK 
evaluable participants, 5 women had MPA levels <0.1 ng/mL at 12 weeks after a single 
dose of DMPA was administered. None of these 5 women, however, had any evidence 
of ovulation (serum progesterone levels remained below 5 ng/mL). In a study by Smit et 
al. [56] in 94 women, all but one woman had MPA levels above 0.1 ng/mL at 12 weeks 
after DMPA administration. These 94 women had received either a single dose or 
multiple doses of DMPA. Therefore, based on the single dose studies, the proportion of 
women with MPA levels <0.1 ng/mL (sub-therapeutic MPA levels) 12 weeks post-dose is 
thought to be about 6% in normal DMPA use, although a study conducted by Trussell 
[57] showed that there is a contraceptive failure rate of about 0.3% when DMPA is used 
correctly. 
 
The primary analysis outcome will be the proportion of women with sub-therapeutic MPA 
levels (<0.1 ng/mL) at 12 weeks. A one-sided binomial test with significance level 0.05 
will be used to test the null hypothesis that the proportion of women with sub-therapeutic 
MPA level is 6% or less. A sample size of 42 women provides 90% power to reject the 
null hypothesis if the proportion of women with sub-therapeutic MPA levels in this study 
is at least 21% (this is 15% or higher increase from the 6% threshold).  With a sample 
size of 42 women, the underlying true proportion will be declared as statistically 
significant increase if 6 or more women have sub-therapeutic MPA levels at 12 weeks 
(this is equivalent to saying that 90% CI for the underlying proportion is entirely above 
the 6% threshold). Based on the results from a PK study of oral contraceptives 
containing ethinyl estradiol (estrogen) and norethindrone (progestin) which are 
metabolized by CYP3A4 enzyme [58], the study team considers that the underlying 
proportion of women with sub-therapeutic MPA levels of 21% or higher (15% or higher 

 
42 
A5338 
Final Version 1.0 
 
 
12/12/14 
 
increase from the 6% threshold) is plausible in the setting of coadministration with EFV 
and RIF. 
 
The statistical power was also examined to see if the sample size will achieve a 
plausible power to detect a clinically meaningful decrease (30%) in MPA concentration 
at 12 weeks (MPA Cmin) as one of the secondary objectives. With a significance level of 
0.05, a one-sided t-test showed about 91% and 84% power to detect a 30% decline 
when the coefficient of variation (CV) is 60% and 70%, respectively (in the ACTG study 
A5093, CV of MPA Cmin was approximately 57% when coadministered with EFV). We 
note that this power was examined in loge-scale since it is known that PK parameter Cmin 
has a log-normal distribution.  
 
To protect against 10% loss of the primary outcomes after study accrual is closed, the 
study will enroll a total of 46 women. (In the ACTG DMPA study, A5093, the loss of the 
primary outcomes of week 12 was 9.8% [6 of 61 participants] due to either sample 
specimen loss or assay results not available.) 
 
A participant is considered to be evaluable for the primary objective if the participant 
completes the MPA PK sampling during the study period of 12 weeks after DMPA 
administration. The participant replacement criteria are described in sections 8.1 and 
8.2. 
 
The study team anticipates that the study will enroll approximately 4 participants per 
month and it will take approximately 12 months to meet the target enrollment for the 
study. 
 
9.5 
Monitoring 
 
The study team will monitor participant accrual to ensure the target number of evaluable 
participants is enrolled. Study sites will be required to report all participant dropouts and 
noncompliance, including missing PK sample times/visits to the study team as soon as 
they occur. The study team will make decisions on participant’s replacement on 
conference calls or by emails. 
 
During the study, the safety and tolerability of the study medications will be monitored by 
means of adverse events reports representing laboratory and clinical data, such as 
Toxicity Summary reports or Phase I/II reports provided by ACTG DMC. It is required for 
study sites to enter these data into the DMC database within a specified time period for 
data entry. The study team will discuss these reports on regularly scheduled conference 
calls or by email. It is the responsibility of the study team to interpret the adverse event 
data and make any decisions needed to protect study participants from undue risk. Any 
concerns will be presented to the DAIDS Clinical Representative. 
 
9.6 
Analyses 
 
A detailed statistical analysis plan will be developed after protocol Version 1.0 is finalized 
and before the study is open to accrual. The following will provide a summary of 
analyses that will state key analysis approaches.

Final Version 1.0 
 
 
12/12/14 
 
 
9.6.1 Analyses of Primary Outcome Measurements 
 
The proportion of participants with sub-therapeutic MPA levels (<0.1 ng/mL) will 
be estimated based on the participants who complete the PK sampling at 12 
weeks after DMPA administration. A 90% confidence interval (CI) will be 
provided for proportion using Clopper-Pearson exact method for binomial 
measurements. This CI will provide us reasonable evidence that the true 
proportion is greater than the threshold (6%), by determining whether the 90% CI 
is entirely above the threshold. 
 
Individual-specific MPA concentration-time curves in the elimination phase will be 
estimated by fitting loge-linear regression models to the data of MPA 
concentrations obtained at time of maximum MPA concentration and later. These 
estimated individual elimination curves will then be used to estimate the times 
(weeks) where MPA concentration levels reach at 0.1 ng/mL. We will present 
descriptive statistics of these estimated weeks including mean, SD, median, 
interquartile range, minimum and maximum. Mixed-effects model analysis 
(allowing individual elimination slope to be both fixed and random variable) with 
repeated measurements within individual participants will also be performed to 
estimate the times for comparison purposes with the results obtained using the 
log-linear regression models fitted for individual participants. These modeling 
approaches will provide the population mean estimate of the time where MPA 
concentration level reaches at 0.1 ng/mL with 90% CI, which will guide us to 
determine optimal dosing frequency of DMPA in the study population. Details of 
these modeling approaches will be described in the statistical analysis plan that 
will be generated separately and approved by study team. 
 
Descriptive statistics of plasma progesterone levels will be tabulated by study 
week. If there are participants with progesterone levels >5 ng/mL, the proportion 
and percentage of participants with progesterone levels >5 ng/mL will be 
tabulated by study week. 
 
Relationships of plasma progesterone levels with MPA concentration levels will 
be investigated by exploratory plots and using nonlinear regression models to 
better understand a lower limit of therapeutic MPA level that could prevent 
ovulation. This analysis will be based on MPA and plasma progesterone levels 
observed at week 10 and 12. If MPA clearance is truly induced by the 
coadministered drugs, MPA levels at these times may be low enough that 
plasma progesterone may have risen. We note that if plasma progesterone levels 
have not begun to rise by week 10/12, this analysis may have a poor statistical 
power.    
 
9.6.2 Analyses of Secondary Outcome Measurements 
 
9.6.2.1 Estimation of MPA PKs in presence of EFV and RIF: 
MPA PK parameters AUC0-12wk, concentration at week 12 (trough 
concentration, Cmin). Cmax, CL/F, and T1/2 will be estimated using non-

 
44 
A5338 
Final Version 1.0

compartmental approach and descriptive statistics of these PK 
parameters will be presented. For the purpose of evaluating whether 
these PK parameters are significantly different from those in women not 
on the companion drugs, those PK parameters will be compared to 
those from the historic controls (A5093 Control Arm) using 
nonparametric two-sample Wilcoxon test. GMRs in MPA PK parameters 
of co-administration over administration-alone and associated 90% CIs 
will also be presented to provide magnitude of the differences as a 
supplementary analysis. 
 
9.6.2.2 Estimation of time and variability in time to reach a MPA 0.1 ng/mL: 
Times (weeks) and variability in times to reach MPA 0.1 ng/mL will be 
estimated using the analysis methods described in section 9.6.1.    
 
9.6.2.3    Estimation of the proportion of participants reaching MPA level <0.1 
ng/mL: 
The proportion and percentage of participants with MPA concentration 
levels <0.1 ng/mL will be summarized by each of the study weeks 8 and 
10.  90% CI for proportion at each week will be presented using 
Clopper-Pearson exact method. 
 
9.6.2.4    Evaluation of toxicity and safety: 
Signs and symptoms, chemistry and hematology with toxicity Grade ≥3 
will be tabulated by study week.  
 
9.6.3 Analyses of Exploratory Outcome Measurements 
 
9.6.3.1    Inter-individual differences in PK parameters between EFV, DMPA, 
and/or RIF when stratified by human genetic variants that are known to 
predict altered pharmacokinetics of EFV (eg, CYP2B6) and RIF (eg, 
SLCO1B1) will be investigated using descriptive statistics of PK 
parameters categorized by metabolizer status (based on the human 
genetic variants) and performing an nonparametric ordered test (eg, 
Jonckheere-Terpstra trend test) in PK parameters for the priori ordering 
of metabolizer groups in the co-administration if data allows. 
 
9.6.3.2    Associations of MPA PK parameters with baseline BMI and/or body 
fat percentage will be examined using visual plots (eg, scatter plots) 
and investigated using linear or nonlinear regression models. Changes 
of BMIs and body fat percentages at study week 12 from baseline will 
be descriptively summarized. 
 
 
10.0 
PHARMACOLOGY PLAN 
 
Women stable on an EFV and 2 NRTIs-based regimens, who are on RIF and INH, and 
who have not received DMPA within the last 180 days, will receive one dose of DMPA at 

 
45 
A5338 
Final Version 1.0 
 
 
12/12/14 
 
study entry. An optional dose of DMPA will be available at no cost to all study 
participants, after all week 12 study evaluations are completed. Refer to section 5.1.1 for 
the allowed NRTIs and section 5.4.2 for the prohibited NRTI combinations.  
 
The primary PK analysis is described in section 9.6. The secondary PK analysis 
employing a population approach and nonlinear mixed effects modelling is described in 
this section. 
 
10.1 
Pharmacology Objectives 
 
Using nonlinear mixed-effects (NLME) modeling, the population PK of MPA will be 
described in the population in order: 
 
10.1.1 To describe the structural PK model for MPA given in the DMPA formulation. 
 
10.1.2 To identify and quantify the effects of covariates influences on PK (eg, weight 
[including total, fat and lean components], age, time on TB treatment, time on 
ART, adherence to ART and TB treatments, CYP2B6 genotype, etc.). 
 
10.1.3 To characterize between subject and random unexplained components of the PK 
variability. 
 
10.1.4 To predict the time at which the proportion of women with MPA <0.1 ng/L 
matches that at 12 weeks from historical data. 
  
10.2 
Pharmacology Study Design 
 
Doses of all ARV and TB medications taken for 48 hours prior to PK will be collected on 
the CRF at weeks 2, 4, 6, 8, 10, and 12. The participant should be contacted one week 
prior to the scheduled visit to reinforce the importance of 100% adherence to RIF and 
EFV and of her upcoming appointment. A participant who misses 2 or more doses of RIF 
and EFV within one week prior to the scheduled PK sampling at weeks 2, 4, 6, 8, 10, 
and 12 will have the visit rescheduled to one week later. For the week 10 and week 12 
visits, the rescheduled PK sampling should be strictly within the original visit window for 
that visit. The schedule for the remaining visit weeks should not be changed. The rules 
for replacing participants who do not complete the PK are described in sections 8.1 and 
9.5.  
 
A single 4 mL blood sample for PK will be collected just prior to DMPA injection at week 
0 and at the scheduled visits at weeks 2, 4, 6, 8, 10, and 12. The blood sample will be 
centrifuged within 1 hour of collection to separate the plasma which will be stored at -
70°C or colder until assay for MPA and progesterone. 
 
The ACTG Pharmacology Specialty Laboratory at the University of Cape Town will use 
liquid chromatography-tandem mass spectrometry (LC MS/MS) to measure MPA and 
progesterone in the plasma. The assay methods will be validated and submitted to 
Clinical Pharmacology Quality Assurance (CPQA) for review.

10.3 
Primary and Secondary Data, Modeling, and Data Analysis 
 
The concentration vs. time data for DMPA will be analyzed using NLME modelling using 
the software NONMEM (Version 7.2) [57].  
 
The modelling approach will follow a stepwise procedure to first identify the structural 
model best describing the data, and then incorporate the effect of the study covariates 
such as weight, age, and effect of concomitant anti-retroviral and anti-tuberculosis 
treatment. 
 
Various structural pharmacokinetic models will be evaluated, focusing on correctly 
characterizing the absorption after intra-muscular injection. The tested models will 
include one, two, and three compartments disposition with first-order elimination and 
zero-, first-order, or saturable absorption.  
 
Statistically significant variability and correlation estimates for the PK parameters will be 
included and the covariates of interest will be evaluated with respect to their impact on 
the PK parameters and their variability. 
 
Allometric scaling [59] will be used to account for the effect of body size on the PK 
parameters, using total body weight or fat-free mass. Other covariate effects will be 
evaluated and included if they significantly improve the ability of the model to describe 
the data. The effect of adherence to and time on ART and TB regimens, and CYP2B6 
genotype (if available), will be investigated on clearance.   
 
Concentrations below the limit of quantification will be included in the analysis and 
handled with established methods [60]. 
 
The tools used for model development and graphical and statistical diagnostics will 
include Xpose, and Perl Speaks NONMEM, and Pirana [61].  
  
The PK profiles will be analyzed using post-hoc Bayesian methods to extract information 
such as peak concentration, overall exposure (AUC), and time above target 
concentration. Simulations will be employed to explore the pharmacokinetic profiles, 
their variability in a population, and how they are affected by weight, concomitant anti-
retroviral or anti-tuberculosis treatment, other covariates found significant, and possibly 
under different dosing scenarios, and to predict the time at which the proportion of 
women with MPA <0.1 ng/L matches that at 12 weeks from historical data. 
 
10.4 
Anticipated Outcomes 
 
The anticipated outcomes are described in the section above. They are the model 
outputs: firstly the population PK of MPA will be described using the primary model 
parameters and secondary measure estimates. Covariate effects on the model 
parameters will be identified and quantified. The model will ascribe variability (due to 
fixed effects, inter individual and random unexplained variability) with accuracy. 
Secondly, simulations will predict the optimal dosing frequency to achieve a target 
trough concentration of >0.1 ng/mL in the target proportion of women.

10.5 
Pharmacogenomics – Host Genetic Analysis 
 
Inter-individual differences in host genes (eg, those that encode drug-metabolizing and 
transporter proteins) have been associated with inter-individual differences in plasma PK 
of EFV [38, 39, 40, 41, 42, 43] and RIF [62]. The study will therefore evaluate human 
genetic polymorphisms that are known to affect steady-state plasma PK of EFV and RIF. 
Among study participants that receive EFV and RIF, analyses of PK data will take into 
consideration such polymorphisms. If additional polymorphisms are reported to affect 
sex hormones, these may also be studied.

SAMPLE INFORMED CONSENT 
 
For protocol: 
An Open-Label, Non-Randomized Study of Pharmacokinetic Interactions Among Depot 
Medroxyprogesterone Acetate (DMPA), Rifampicin (RIF), and Efavirenz (EFV) in Women Co-
Infected with Human Immunodeficiency Virus (HIV) and Tuberculosis (TB) 
Final Version 1.0, 12/12/14 
 
 
SHORT TITLE FOR THE STUDY: DMPA in HIV/TB (PRIDE-HT), Final Version 1.0, 12/12/14 
 
 
INTRODUCTION 
 
You are being asked to take part in this research study because you are a woman infected with 
the human immunodeficiency virus (HIV), the virus that causes AIDS; have tuberculosis (TB); 
are taking particular anti-HIV and anti-TB medications; will continue to take TB treatment for at 
least 3 months; and are able to get pregnant.  This study is sponsored by the United States 
(US) National Institutes of Health (NIH).  The doctor in charge of this study at this site is: (insert 
name of Principal Investigator).  Before you decide if you want to be a part of this study, we 
want you to know about the study.  
 
This is a consent form. It gives you information about this study.  The study staff will talk with 
you about this information.  You are free to ask questions about this study at any time.  If you 
agree to take part in this study, you will be asked to sign this consent form. You will get a copy 
to keep. 
 
 
WHY IS THIS STUDY BEING DONE? 
 
This study is being done to evaluate the effect of HIV and TB treatment on a commonly used 
birth control method. This study is being done on women who are infected with HIV and TB and 
are taking efavirenz (EFV; Sustiva®; an anti-HIV medication), rifampicin (RIF; an anti-TB 
medication) and isoniazid (INH; an anti-TB medication).  The purpose of this study is to find out 
the best schedule to give depot medroxyprogesterone acetate (DMPA; a hormonal birth control 
method that is given as a shot every 3 months) in women with HIV and TB who are also taking 
EFV and RIF.  This study will also try to find out if a 150 mg injection of DMPA is effective in 
preventing ovulation, the process by which the ovaries (the ovaries are part of the female 
reproductive system) release an egg for fertilization, for 12 weeks in women who are taking EFV 
and RIF.  Another purpose of this study is to find out if it is safe to take RIF, EFV and DMPA at 
the same time.

For this study, DMPA will be provided in the form of an injection.  DMPA is approved by the 
United States Food and Drug Administration (US FDA) for prevention of pregnancy.  The list of 
risks of DMPA is included in this document; the risks are the same that would be encountered 
when DMPA is used outside of the study.   
 
This study will not provide any anti-HIV or anti-TB medications.  The anti-HIV and anti-TB 
medications that participants have to take to be in this study have been approved by the US 
FDA and are not being tested in this study. 
 
 
WHAT DO I HAVE TO DO IF I AM IN THIS STUDY? 
 
Screening 
If you would like to be in this study, after you have read and signed this informed consent form, 
you will come to the clinic for a screening visit to make sure you meet the requirements for 
joining the study.  This visit will take about 1-2 hours.  At this visit: 
• 
Your HIV infection status will be confirmed. If there is no record available, another HIV test 
will be done.  You may have to sign a separate consent form before this is done. 
• 
Your TB infection status will be confirmed. 
• 
You will be asked about your age at the time of your first menstrual period, the first day of 
your last menstrual period, and how often and usual number of days of your menstrual 
periods. 
• 
You will be asked questions about your medical history and any medications you are taking.  
You will also be asked about any anti-TB medications you have ever taken; anti-HIV and 
hormonal birth control mediations you have taken within the last year and other medications 
you have taken within the last 30 days.   
NOTE: You must be taking EFV, RIF and INH to be eligible for the study. 
• 
You will have a complete physical exam, including obtaining your height and weight. 
• 
You will be asked about adherence to your anti-HIV and anti-TB medications (how correctly 
you are taking your medications).  
• 
You will have about 1 tablespoon (15 mL) of blood drawn for routine lab tests for safety.  
You will be told the results of these tests when they become available.  
• 
You will be asked to give a urine sample or have 1 teaspoon (5 mL) of blood drawn to see if 
you are pregnant.  This test must show that you are not pregnant for you to enroll in the 
study.  You will be told the result of the test when it becomes available. 
• 
If it has been more than 35 days since your last menstrual period, you will have an 
additional 2 teaspoons (10 mL) of blood drawn to measure the amount of follicle-stimulating 
hormone (FSH) in your blood.  In women, FSH is the hormone that helps control the 
menstrual cycle and the production of eggs in the ovaries.  You will be told the result of the 
test when it becomes available. 
 
If you do not enroll into the study 
If you decide not to take part in this study or if you do not meet the eligibility requirements, we 
will still use some of your information.  As part of this screening visit, some demographic (for 
example, age), clinical (for example, disease condition, diagnosis), and laboratory (for example, 
pregnancy test, FSH) information is being collected from you so that ACTG researchers may 
help determine whether there are patterns or common reasons why people do not join a study.

Entry 
If you are eligible for the study, you will be contacted to come in for an entry visit, ideally right 
after the start of your menses.  This visit will last about 1-2 hours.  At this visit: 
• 
You will be asked about your menstrual period and if there has been a change in your 
menstrual period since the screening visit. 
• 
You will have a brief physical exam, which will include obtaining your weight and waist 
measurement, and you will be asked about your health and any changes in your medicines 
since your last visit.  
• 
You will be asked about adherence to your anti-HIV and anti-TB medications. 
• 
You will have about 1 tablespoon (15 mL) of blood drawn to measure your viral load (the 
amount of HIV in your blood) and your CD4+/CD8+ cell count (cells that help fight infection).  
You will be told the results of these tests when they become available. 
• 
You will be asked to give a urine sample or have 1 teaspoon (5 mL) of blood drawn to see if 
you are pregnant.  This test must show that you are not pregnant for you to enroll in the 
study.  You will be told the result of the test when it becomes available. 
• 
You will have about 1 teaspoon (4 mL) of blood drawn to measure the level of DMPA in your 
blood.  You will not receive the result of this test. 
• 
You will have 2 tablespoons (30 mL) of blood drawn and stored for future study-related bone 
test (to check signs of bone health) and genetic test (a test of your DNA [genes] to better 
understand how fast your body removes the study drugs from your blood).  Genetic testing 
looks at differences in people’s genes.  Your body, like all living things, is made up of cells, 
and cells contain deoxyribonucleic acid, also known as “DNA”.  DNA is like a string of 
information put together in a certain order.  Parts of the string make up “genes”.  Genes 
contain instructions on how to make your body work and fight disease.  The testing in this 
study will only look at certain genes that are known to have an effect on how your body uses 
hormones.  The tests will not look at any other genes.  You will not receive the results of 
these tests. 
 
After all of these evaluations are completed, you will receive your DMPA injection. 
 
Study Visits 
After your entry visit, you will come to the clinic again 2, 4, 6, 8, 10, and 12 weeks after the visit 
at which you received DMPA.  These study visits will last about 30 minutes to 1 hour. 
 
During most on-study visits: 
• 
You will be asked when you had your last menstrual period. 
• 
You will have a brief physical exam, which will include obtaining your weight and waist 
measurement, and you will be asked about your health and any changes in your medicines 
since your last visit. 
• 
You will be asked about adherence to your anti-HIV and anti-TB medications. 
• 
You will have 2 teaspoons (10 mL) of blood drawn to measure the amount of progesterone 
in your blood.  Progesterone is a female hormone produced by the ovaries when a mature 
egg is released (from the ovary) and is ready to be fertilized (ovulation).  You will not receive 
the result of this test.

• 
You will have about 1 teaspoon (4 mL) of blood drawn to measure the level of DMPA in your 
blood. 
 
In addition, during the week 4 and week 12 on-study visits: 
• 
You will have about 1 tablespoon (15 mL) of blood drawn for routine lab tests for safety.  
You will be told the results of these tests when they become available. 
• 
You will be asked to give a urine sample or have 1 teaspoon (5 mL) of blood drawn to see if 
you are pregnant.  You will be told the result of the test when it becomes available. 
• 
At the week 12 visit only, you will have an additional 2 tablespoons (30 mL) of blood drawn 
to measure your viral load and stored for future study-related bone tests. 
 
You must inform the study doctor if your primary care physician temporarily stops any of your 
anti-HIV and anti-TB medications because of a harmful side effect while you are in the study. 
 
If You Have to Stop the Study Early 
If you leave the study early, you will be asked to come to the clinic for an additional study visit.  
This visit will last about 1 hour.  At this visit: 
• 
You will have a brief physical exam, which will include obtaining your weight, and you will be 
asked about your health and any changes in your medicines since your last visit.  
• 
You will be asked about adherence to your anti-HIV and anti-TB medications. 
• 
You will have about 1 tablespoon (15 mL) of blood drawn for routine lab tests for safety.  
You will be told the results of these tests when they become available. 
• 
You will be asked to give a urine sample or have 1 teaspoon (5 mL) of blood drawn to see if 
you are pregnant.  You will be told the result of the test when it becomes available. 
• 
You will have 2 teaspoons (10 mL) of blood drawn to measure the amount of progesterone 
in your blood. 
 
Other 
The blood samples collected for the test to measure the level of DMPA in your blood may be 
shipped for storage and testing in South Africa. 
 
The blood samples collected for future study-related bone test and genetic test may be shipped 
for storage in the United States until the tests are performed. 
 
Some of your blood that is left over after all required study testing is done may be stored (with 
usual protectors of identity) and used for ACTG-approved HIV-related research.  These leftover 
blood samples may be shipped for storage in the United States for an indefinite period of time.  
Results of testing performed on these blood samples may not be given to you. 
 
Please indicate now if you agree to have your left-over blood samples stored for future ACTG-
approved HIV-related research.  You may change your mind at any time and your samples will 
be destroyed.

HOW MANY PEOPLE WILL TAKE PART IN THIS STUDY? 
 
About 46 women will take part in this study. 
 
 
HOW LONG WILL I BE IN THIS STUDY? 
 
You will be in this study for about 12 weeks (about 3 months).   
 
 
WHY WOULD THE DOCTOR TAKE ME OFF THIS STUDY EARLY? 
 
The study doctor may need to take you off the study early without your permission if: 
• 
You miss two study visits in a row. 
• 
You do not take the RIF and EFV medications as you are supposed to and you then do not 
take the RIF and EFV prior to your rescheduled visit to collect the blood sample to measure 
the level of DMPA in your blood. 
• 
The blood sample to measure the level of DMPA in your blood could not be collected for two 
study visits in a row or at the week 10 or week 12 study visit (for example, because you 
missed the visit). 
• 
You do not take your anti-HIV and anti-TB medications as you are supposed to. 
• 
You have a severe adverse reaction to your anti-TB and anti-HIV medications and your 
primary care physician has taken you off these drugs. 
• 
You need a treatment that you may not take while on the study. 
• 
Your primary care physician no longer thinks that participating in the study is in your best 
interest or continuing in the study may cause you harm. 
• 
The doctor in charge of the study believes that you may not be able to comply with the 
study, and that this may cause you harm or injury, or may affect the results of the study. 
• 
You are not able to complete the study visits as required by the study. 
• 
The study is stopped or cancelled. 
 
If I have to permanently leave the study, how would DMPA be provided? 
If you complete all 12 weeks of the study, you may be able to receive an additional one dose of 
DMPA at no cost to you after all the evaluations at week 12 are completed. After you have 
completed your study participation, the study will not be able to continue to provide you with 
DMPA that you received on the study. If continuing to take these or similar drugs/agents would 
be of benefit to you, the study staff will discuss how you may be able to obtain them. 
 
 
WHAT ARE THE RISKS OF THE STUDY? 
 
The drugs used in this study may have side effects, some of which are listed below. Please note 
that these lists do not include all the side effects seen with these drugs. These lists include the 
more serious or common side effects with a known or possible relationship. If you have 
questions concerning the additional study drug side effects please ask the medical staff at your 
site.

Risks of DMPA 
• 
Changes in menstrual periods 
• 
Conditions that may lead to the development of blood clots (thromboembolic disorders) 
involving deep veins of the legs, lung, and brain (stroke) 
• 
Headache 
• 
Nervousness 
• 
Dizziness 
• 
Difficulty falling and/or staying asleep 
• 
Depression (a mood disorder that causes a persistent feeling of sadness and loss of interest 
that interferes with your everyday life) 
• 
Swelling/water retention 
• 
Changes in vaginal secretions 
• 
Pain in the stomach area or belly

• 
Breast tenderness 
• 
Sensitive skin, hives, and rash 
• 
Acne 
• 
Loss of scalp hair 
• 
Delayed return to fertility 
• 
Weight gain 
• 
Thinning of the bones (Loss in bone density) 
• 
Joint pain 
• 
Pregnancy 
• 
Low sex drive 
 
Studies of women who have used different forms of contraception found that women who used 
DMPA over long periods of time had no increased risk of developing cancer of the breast, ovary, 
uterus, cervix or liver.  However, women under 35 years of age whose first exposure to DMPA 
was within the previous 4 to 5 years may have a slightly increased risk of developing breast 
cancer similar to that seen with oral contraceptives. 
 
At least one research study in humans has suggested an increased rate of HIV infection to the 
uninfected partners of DMPA users, while other studies have found no such relationship. A large 
clinical trial addressing the issue of DMPA and the risk of transmitting HIV is currently ongoing, 
and the WHO has issued guidelines saying that women with HIV can use DMPA without 
restrictions. 
 
If you experience any of the side effects of DMPA, you must contact the study staff who will 
advise you to come to the clinic for assessment. Depending on the severity of your symptoms, 
the study doctor will either manage your symptoms or refer you to the hospital for care. If 
symptoms are mild, the study doctor will give you treatment but for severe symptoms, you will 
be referred to the hospital immediately. 
 
Risks of Drawing Blood  
Taking blood may cause some discomfort, bleeding, bruising, and/or swelling where the needle 
enters the body, lightheadedness, and in rare cases, fainting or infection.

Risks of Social Harm 
It is possible that participating in this study will make it difficult for you to keep your HIV or TB 
status secret from people close to you. This may lead to unwelcome discussions about or 
reactions to your HIV or TB status. Please talk with the study staff if you have any concerns in 
this regard. 
 
Other Information 
There is a risk of serious and/or life-threatening side effects when non-study medications are 
taken with the study drugs. For your safety, you must tell the study doctor or nurse about all 
medications you are taking before you start the study and also before starting any new 
medications while on the study. Also, you must tell the study doctor or nurse before enrolling in 
any other clinical trials while on this study. 
 
 
ARE THERE RISKS RELATED TO PREGNANCY? 
 
Women who become pregnant while receiving DMPA may have an increased risk of delivering 
a baby that has birth defects.  For this reason, we do not recommend that you allow yourself to 
become pregnant while using this medication.  It is not known if taking DMPA together with anti-
HIV and anti-TB drugs affects the levels of DMPA in your blood. 
 
DMPA injections should not be taken during pregnancy.  Pregnant women may not join the 
study.  If you are having sex that could lead to pregnancy, you must agree not to become 
pregnant. 
 
If you decide to participate in this study, you must use at least one barrier method of birth 
control during this study because it is unknown if various combinations of anti-HIV and anti-TB 
medications make DMPA less effective.  You should NOT use DMPA as your ONLY method of 
birth control. 
 
You may choose one or more of the birth control methods listed below:  
• 
Male condom with or without spermicide (a cream or gel that kills sperm) 
• 
Female condom with or without spermicide 
• 
Diaphragm or cervical cap with spermicide 
• 
Non-hormonal intrauterine device (IUD) 
• 
Bilateral tubal ligation (surgery that involves blocking the fallopian tubes [the part of the 
female reproductive system that carries the eggs from the ovary to the uterus or womb] to 
prevent the egg from being fertilized) 
• 
Male partner vasectomy (surgery that prevents the release of sperm from the male partner) 
 
You must NOT use birth control pills during this study. 
 
If you can become pregnant, you must have a pregnancy test before you enter this study.  The 
test must be negative. If you think you may be pregnant at any time during the study, tell your 
study staff right away.  The study staff will talk to you about your choices.  Your choice will not 
affect your usual medical care provided by your doctor.  You may be allowed to join future 
research studies, if you qualify.

If you become pregnant while on study, you will continue taking your anti-HIV and anti-TB 
medications and continue to be seen at the scheduled study visits until you complete the study.  
You will have the study evaluations performed at each visit except the test to measure the level 
of DMPA in your blood. 
 
If you become pregnant while on study, the study staff would like to obtain information from you 
about the outcome of the pregnancy (even if it is after your participation in the study ends). If 
you are taking anti-HIV drugs when you become pregnant, your pregnancy will be reported to 
an international database that collects information about pregnancies in women taking anti-HIV 
drugs. This report will not use your name or other information that could be used to identify you. 
 
 
ARE THERE BENEFITS TO TAKING PART IN THIS STUDY? 
 
If you take part in this study, it is unlikely that there will be any direct benefit to you. It is also 
possible that you may receive no benefit from being in this study. Information learned from this 
study may help others who have HIV and TB, and improve our understanding of the use of 
DMPA in HIV-infected women. 
 
 
WHAT OTHER CHOICES DO I HAVE BESIDES THIS STUDY? 
 
Instead of being in this study you have the choice of: 
• 
treatment with prescription drugs available to you or at your local clinic 
• 
treatment with experimental drugs, if you qualify  
• 
no treatment 
 
Please talk to your doctor about these and other choices available to you. Your doctor will 
explain the risks and benefits of these choices. 
 
 
WHAT ABOUT CONFIDENTIALITY? 
 
Efforts will be made to keep your personal information confidential. We cannot guarantee 
absolute confidentiality. Your personal information may be disclosed if required by law. Any 
publication of this study will not use your name or identify you personally. 
 
Your records may be reviewed by the ACTG, Office for Human Research Protections, (insert 
name of site) institutional review board (IRB)/ethics committee (EC), National Institutes of 
Health (NIH), local National Health Organization, other government agencies, study staff, and 
study monitors. 
 
A description of this clinical trial will be available on www.ClinicalTrials.gov. This Web site will 
not include information that can identify you. At most, the Web site will include a summary of the 
results. You can search this Web site at any time.
