Arm Type

Experimental

Experimental

Arm Label

Trimethoprim/sulfamethoxazole (TMP-SMX)

Doxycycline (DOXY)

Arm Description

TMP-SMX will be dosed as follows: for adults, 160/800 mg administered as two single strength (SS) over-encapsulated tablets (equivalent to one double strength (DS) tablet) twice daily. As dosages of these medications may be lower in children with lower body weight (<40 kg), we will use weight based liquid medications for children < 40 kg (TMP/SMX dosed based on 8-10 mg/kg of TMP daily, divided into two daily doses) for those children who are under 40 kg in weight. As dosages of these medications are higher in persons with high body weight (>100 kg), we will use TMP/SMX 160/800 mg administered as four single strength (SS) over-encapsulated tablets (equivalent to two double strength (DS) tablet) twice daily.

DOXY will be dosed as follows: for adults, two 50 mg tabs (100 mg total) given twice daily. As dosages of these medications may be lower in children with lower body weight (<40 kg), we will use weight based liquid medications for children < 40 kg (DOXY 2.2 mg/kg twice daily) for those children who are under 40 kg in weight. The doxycycline dose will remain the same for persons with high body weight (>100 kg) and four additional placebo tabs will be given to subjects > 100 kg randomized to doxycycline.

Outcomes

Primary Outcome Measures

Clinical cure at Early Clinical Response (ECR) visit
Clinical cure is the absence of clinical failure which is defined as occurrence of any one of the following events at ECR: Fever (one or more temperature readings of ≥37.7°C between 48 and 72 hours); Spread of lesion defined as an increase in size (length, width, or area) of the redness, edema, and/or induration such that the size of the lesion is greater than the size at baseline; Administration of rescue antibacterial drug therapy or any non-trial antibacterial drug therapy for the treatment of SSTI prior to the ECR evaluation; Requires an additional unplanned surgical procedure after start of therapy; Death.

Secondary Outcome Measures

Clinical cure at the End of Treatment (EOT) visit
Clinical cure will be defined as complete or nearly complete resolution of baseline signs and symptoms of the primary infection such that no further treatment with antibiotics is needed
Clinical cure at the One Month Follow-up (OMFU) visit
Clinical cure will be defined as complete or nearly complete resolution of baseline signs and symptoms of the primary infection such that no further treatment with antibiotics is needed
Adverse events
An adverse event (AE) is defined as any unfavorable or undesirable effect (sign, symptom, laboratory abnormality, or condition), regardless of causal relationship to study procedures or participation that occurs in a subject while enrolled in this clinical trial. Any medical condition that is present at the time that the subject is screened should be considered as baseline and not reported as an AE. However, if it deteriorates at any time during the study, it should be recorded as an AE. The occurrence of an AE may come to the attention of study personnel during study visits and interviews of a study recipient presenting for medical care, or upon review by a study monitor.
Adverse events that are treatment limiting
An adverse event (AE) is defined as any unfavorable or undesirable effect (sign, symptom, laboratory abnormality, or condition), regardless of causal relationship to study procedures or participation that occurs in a subject while enrolled in this clinical trial. Any medical condition that is present at the time that the subject is screened should be considered as baseline and not reported as an AE. However, if it deteriorates at any time during the study, it should be recorded as an AE. The occurrence of an AE may come to the attention of study personnel during study visits and interviews of a study recipient presenting for medical care, or upon review by a study monitor.
Relapse/recurrent SSTI at One Month Follow-Up (OMFU)
Relapse will be defined as a return of the original infection after initial improvement prior to or at the OMFU visit. Recurrence will be defined as a return of skin infection at the original site, even if considered to be a separate occurrence, after the OMFU visit or a skin infection at a new site of infection.
Relapse/recurrent SSTI at 6 Month Follow-Up (6MFU)
Relapse will be defined as a return of the original infection after initial improvement prior to or at the 6MFU visit. Recurrence will be defined as a return of skin infection at the original site, even if considered to be a separate occurrence, after the 6MFU visit or a skin infection at a new site of infection.
Relapse/recurrent SSTI at 12 Month Follow-Up (12MFU)
Relapse will be defined as a return of the original infection after initial improvement prior to or at the 12MFU visit. Recurrence will be defined as a return of skin infection at the original site, even if considered to be a separate occurrence, after the 12MFU visit or a skin infection at a new site of infection.

5. Study Description

Brief Summary
The purpose of this study is to compare how well two different antibiotics, doxycycline (DOXY) and trimethoprim/sulfamethoxazole (TMP/SMX), work at curing uncomplicated skin and soft tissue infection (uSSTI) such as 1.Boils (pus in the skin, also known as abscesses and furuncles) or 2. Infections that appear only on the skin surface (called cellulitis and erysipelas) that have pus.
Detailed Description
This is a phase IIb multicenter, randomized, double-blind trial in which enrolled subjects with abscess or cellulitis will be treated with either DOXY or TMP-SMX. The overall objective is to provide a clinically relevant treatment strategy for uSSTI in children and adults in areas where CA-MRSA is prevalent. Out-patient subjects, both children and adults with abscess and/or purulent cellulitis will be enrolled into a randomized, double-blind trial in which enrolled subjects will be treated with either DOXY or TMP-SMX. Background: Staphylococcus aureus is the most commonly identified cause of skin infections. In the last 15 years, there also has been an large increase in Staphylococcus aureus skin infection attributable to CA-MRSA (Methicillin-resistant Staphylococcus aureus) throughout the United States. However, optimal treatment remains unclear and several commonly used antibiotics such as doxycycline are commonly used but understudied. As resistance among CA-MRSA strains to commonly used antibiotics such as clindamycin continues to increase, there is a need to understand the relative safety and efficacy of alternative treatments, such as doxycycline. This clinical trial will evaluate DOXY and TMP-SMX for the outpatient management of uSSTI in two metropolitan areas, Los Angeles and St. Louis, cities with high prevalence of CA-MRSA. This trial will test important unanswered hypotheses relating to the treatment of CA-MRSA uSSTI and it will advance healthcare providers' ability to successfully manage adults and children with uSSTIs in areas where CA-MRSA is prevalent. Methods: Out-patient subjects, both children and adults with abscess and/or purulent cellulitis will be enrolled into a randomized, double-blind trial in which enrolled subjects will be treated with either DOXY or TMP-SMX. Using a 1:1 randomized controlled trial of 462 subjects, the investigators aim to 1) compare the cure rate of DOXY to that of TMP-SMX for the treatment of patients throughout the study 2) compare rates of adverse events and of adverse events that are treatment limiting between DOXY and TMP-SMX 3) estimate relapse and recurrence of uSSTI among patients treated with DOXY and of TMP-SMX 4) estimate treatment failure among patients with uSSTI colonized with S. aureus at the anterior nares and oropharynx.
