It is not yet known whether ciprofloxacin is more effective than cephalexin in preventing cancer recurrence in patients who are undergoing surgery to treat bladder cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of ciprofloxacin with that of cephalexin in preventing recurrence of cancer in patients who are undergoing surgery for bladder cancer.
NCT00179959 ↗ The Impact of Treating Staphylococcus Aureus Infection and Colonization on the Clinical Severity of Atopic Dermatitis Completed Johnson & Johnson Phase 4 2005-09-01 Staphylococcus aureus (S. aureus) infection is perceived not only as a common secondary complication of atopic dermatitis (AD), but also as a culprit in the worsening of this condition. In addition, the recent development of community acquired methicillin-resistant S. aureus (CA-MRSA) has presented a new challenge to our management of AD, both in treatment of acute infections and maintenance therapy. The investigators would like to perform a randomized investigator-blinded placebo-controlled study of children aged 6 months to 17 years with moderate to severe atopic dermatitis with clinical signs of secondary bacterial infection to study: 1) the prevalence of CA-MRSA in our patient population; 2) the relationship of sensitivity of the S. aureus organism cultured from the infected lesion(s) to clinical response to oral cephalexin therapy and severity of the AD; and 3) whether concurrent treatment of S. aureus infection initially with nasal mupirocin ointment and sodium hypochlorite (bleach) baths can result in long-term S. aureus eradication and clinical stability.

NCT00179959 ↗ The Impact of Treating Staphylococcus Aureus Infection and Colonization on the Clinical Severity of Atopic Dermatitis Completed Northwestern University Phase 4 2005-09-01 Staphylococcus aureus (S. aureus) infection is perceived not only as a common secondary complication of atopic dermatitis (AD), but also as a culprit in the worsening of this condition. In addition, the recent development of community acquired methicillin-resistant S. aureus (CA-MRSA) has presented a new challenge to our management of AD, both in treatment of acute infections and maintenance therapy.

NCT00187759 ↗ Placebo Controlled Study of Antibiotic Treatment of Soft Tissue Infection Completed University of California, San Francisco N/A 2004-11-01 This study is to determine whether antibiotic therapy is needed for patients with non-life threatening soft tissue infections. Most patients with these soft tissue infections are presently treated with antibiotics. Many of these infections resolve without proper antibiotic treatment. Treatment of patients with antibiotics after surgical drainage of an abscess may not be necessary and indiscriminate use of antibiotics may lead to colonization by drug-resistant organisms. Subsequent infection by drug resistant organisms may limit the choice of antibiotics in more complicated infections. A comparison between antibiotic treatment and no antibiotic treatment in surgically treated, uncomplicated soft tissue infections is needed to address this very important question.

Cephalexin: Clinical Trials, Market Analysis, and Projections

Clinical Trials Update

Recent Studies on Cephalexin Efficacy

One of the most significant clinical trials involving cephalexin was a multicenter, double-blind, randomized superiority trial conducted to determine whether adding trimethoprim-sulfamethoxazole to cephalexin enhances the clinical cure rate for uncomplicated cellulitis.

  • Methodology and Participants: The trial enrolled 500 outpatients older than 12 years with cellulitis, recruited from five US emergency departments between April 2009 and June 2012. Participants were randomized to receive either cephalexin plus trimethoprim-sulfamethoxazole or cephalexin plus placebo for 7 days[1].
  • Outcomes: The study found that the clinical cure rates were not significantly different between the two groups. In the per-protocol analysis, the cure rates were 83.5% for the cephalexin plus trimethoprim-sulfamethoxazole group and 85.5% for the cephalexin alone group. The modified intention-to-treat analysis showed cure rates of 76.2% and 69.0%, respectively. The difference in the intention-to-treat analysis was not statistically significant, although it included the minimal clinically important difference of 10%[1].

Implications of the Study

The study suggests that, for uncomplicated cellulitis, the addition of trimethoprim-sulfamethoxazole to cephalexin may not provide a significant clinical benefit. This finding is crucial for guiding treatment protocols and optimizing antibiotic use.
