This table shows clinical trials for potential 505(b)(2) applications. See the next table for all clinical trials

Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
New Dosage	NCT01168895 ↗	Study in COPD (Chronic Obstructive Pulmonary Disease) Subjects to Investigate Safety, Tolerability, and Pharmacokinetics of Ciprofloxacin After Single Dose Inhalations of 50 mg and 75 mg Ciprofloxacin Inhalation Powder	Completed	Bayer	Phase 1	2010-07-01	The purpose of this study is to compare the safety and pharmacokinetics of ciprofloxacin after inhalation of single 52.5 and 48.75 mg doses in COPD patients. In this study the 48.75 mg dose will be administered for the first time using a new high dose strength (i.e. one capsule containing 75 mg powder = 48.75 mg ciprofloxacin) formulation. Safety investigations will focus on local tolerability in the lung and evaluate whether the patient can inhale the higher amount of powder compared to the lower dose strength. Pharmacokinetics is to see how the body absorbs, distributes, breaks down and gets rid of the study drug. Results from this study will be used to decide whether the new dose strength is suitable for larger clinical trials planned for the COPD patients population.

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00000641 ↗	A Phase II/III Trial of Rifampin, Ciprofloxacin, Clofazimine, Ethambutol, and Amikacin in the Treatment of Disseminated Mycobacterium Avium Infection in HIV-Infected Individuals.	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 2	1969-12-31	To compare the effectiveness and toxicity of two combination drug treatment programs for the treatment of disseminated Mycobacterium avium infection in HIV seropositive patients. [Per 03/06/92 amendment: to evaluate the efficacy of azithromycin when given in conjunction with either ethambutol or clofazimine as maintenance therapy.] Disseminated M. avium infection is the most common systemic bacterial infection complicating AIDS in the United States. The prognosis of patients with disseminated M. avium is extremely poor, particularly when it follows other opportunistic infections or is associated with anemia. Test tube studies and clinical data indicate that the best treatment program may include clofazimine, ethambutol, a rifamycin derivative, and ciprofloxacin. Test tube and animal studies indicate that amikacin is a bactericidal (bacteria destroying) drug that works better when used with ciprofloxacin. Its role in treatment programs is a key issue because of toxicity and because it must be administered parenterally (by injection or intravenously).
NCT00002850 ↗	Antibiotic Therapy in Preventing Early Infection in Patients With Multiple Myeloma Who Are Receiving Chemotherapy	Completed	Eastern Cooperative Oncology Group	Phase 3	1997-03-01	RATIONALE: Giving antibiotics may be effective in preventing or controlling early infection in patients with multiple myeloma and may improve their response to chemotherapy. PURPOSE: This randomized clinical trial is studying antibiotics to see how well they work compared to no antibiotics in preventing early infection in patients with multiple myeloma.
NCT00002850 ↗	Antibiotic Therapy in Preventing Early Infection in Patients With Multiple Myeloma Who Are Receiving Chemotherapy	Completed	National Cancer Institute (NCI)	Phase 3	1997-03-01	RATIONALE: Giving antibiotics may be effective in preventing or controlling early infection in patients with multiple myeloma and may improve their response to chemotherapy. PURPOSE: This randomized clinical trial is studying antibiotics to see how well they work compared to no antibiotics in preventing early infection in patients with multiple myeloma.
NCT00002850 ↗	Antibiotic Therapy in Preventing Early Infection in Patients With Multiple Myeloma Who Are Receiving Chemotherapy	Completed	Gary Morrow	Phase 3	1997-03-01	RATIONALE: Giving antibiotics may be effective in preventing or controlling early infection in patients with multiple myeloma and may improve their response to chemotherapy. PURPOSE: This randomized clinical trial is studying antibiotics to see how well they work compared to no antibiotics in preventing early infection in patients with multiple myeloma.
