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.
NCT00003407 ↗	Amifostine and High-Dose Combination Chemotherapy in Treating Patients With Acute Myeloid Leukemia or Chronic Myelogenous Leukemia	Unknown status	National Cancer Institute (NCI)	Phase 2	1998-04-01	RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Chemoprotective drugs, such as amifostine, may protect normal cells from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of amifostine and high-dose combination chemotherapy in treating patients with acute myeloid leukemia or chronic myelogenous leukemia.
NCT00003407 ↗	Amifostine and High-Dose Combination Chemotherapy in Treating Patients With Acute Myeloid Leukemia or Chronic Myelogenous Leukemia	Unknown status	Rush University Medical Center	Phase 2	1998-04-01	RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Chemoprotective drugs, such as amifostine, may protect normal cells from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of amifostine and high-dose combination chemotherapy in treating patients with acute myeloid leukemia or chronic myelogenous leukemia.

Introduction

Ciprofloxacin, an extensively utilized fluoroquinolone antibiotic, plays a pivotal role in managing a broad spectrum of bacterial infections. As global antimicrobial resistance (AMR) intensifies, understanding the current landscape, clinical development updates, and future market trajectory for Ciprofloxacin and its hydrochloride salt forms becomes essential for industry stakeholders. This comprehensive review explores ongoing clinical trials, evaluates market dynamics, and projects future growth trajectories.

Clinical Trials Landscape

Current Clinical Trial Status and Focus

Ciprofloxacin remains a mainstay in infectious disease therapeutics, with numerous clinical trials aimed at optimizing its efficacy, safety profile, and usage in resistant strains. As of 2023, the clinical trial landscape exhibits modest activity, primarily focusing on formulation improvements, resistance management, and new indications.

• Intracellular and Resistant Strain Focus: Recent Phase II and III trials investigate ciprofloxacin's role against resistant bacteria such as multi-drug resistant Pseudomonas aeruginosa and Escherichia coli strains, particularly in complicated urinary tract infections and respiratory infections[^1].

• Alternative Delivery Routes: Trials evaluate topical and nanoparticle-based formulations to enhance bioavailability and reduce systemic side effects, such as in ophthalmic applications or localized wound infections[^2].

• Pediatric and Special Population Studies: Regulatory agencies are encouraging more pediatric trials. Current studies involve assessing pharmacokinetics and safety in children and immunocompromised patients[^3].

Pipeline Developments and Limitations

Despite its proven efficacy, Ciprofloxacin's clinical pipeline faces challenges:

• Resistance Concerns: Collaborations seek to delineate mechanisms of fluoroquinolone resistance, aiming to develop adjunctive therapies or combination regimens to prolong ciprofloxacin's utility[^4].

• New Formulations: Companies explore controlled-release systems and fixed-dose combinations, but regulatory barriers and market saturation slow these developments[^5].

Regulatory and Safety Considerations: Ongoing pharmacovigilance is critical due to concerns related to tendinopathy, CNS effects, and the potential for resistance development. These factors influence clinical trial design and approval timelines.
