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 Combination	NCT00151697 ↗	LANN-study: Lantus, Amaryl, Novorapid, Novomix Study	Completed	Rijnstate Hospital	Phase 3	2005-05-01	Many diabetics gain weight while on insulin therapy. In this study, we evaluate the efficacy of the combination of glimepiride and short-acting insulin on weight control and glucose control. In this study, 150 diabetics whose diabetic control is inadequate while on maximal oral treatment will be randomized to either the new combination treatment or twice daily injections with a mixture of short- and longacting insulin or once-daily injection with a basal insulin analog. The study will compare glucose control and weight gain during a year after randomisation between the three treatments.
OTC	NCT00169299 ↗	Herbal Alternatives for Menopause Symptoms (HALT Study)	Unknown status	National Center for Complementary and Integrative Health (NCCIH)	Phase 4	2001-06-01	Surveys indicate that 25 to 33% of women have moderate to severe menopausal symptoms including hot flashes, night sweats, and disturbed sleep. The treatment of choice in the medical community for these symptoms is hormone replacement therapy, which is estrogen and sometimes progestin. Many women also use over-the-counter herbal remedies. However, less is known about how well these products work, or their safety. Few have undergone the kind of rigorous testing required of prescription drugs and little is known about their long-term effectiveness in relieving symptoms. The purpose of this study is to compare several over-the-counter herbal remedies to hormone replacement therapy. Our primary aim is to look at the effects of these remedies on your self-reported menopausal symptoms. We will also be measuring their effects on other factors known to be affected by hormone replacement therapy: cholesterol, blood sugar, bone density, vaginal cell structure, and blood clotting.

NCT00000110 ↗	Influence of Diet and Endurance Running on Intramuscular Lipids Measured at 4.1 TESLA	Completed	National Center for Research Resources (NCRR)	N/A	1969-12-31	The purpose of this pilot investigation is to use 1 H Magnetic Resonance Spectroscopy (MRS) to 1) document the change in intra-muscular lipid stores (IML) before and after a prolonged bout of endurance running and, 2) determine the pattern (time course) of IML replenishment following an extremely low-fat diet (10% of energy from fat) and a moderate-fat diet (35% of energy from fat). Specifically, the study will evaluate the change in IML following a 2-hour training run and the recovery of IML in response to the post-exercise low-fat or moderate-fat diet in 10 endurance trained athletes who will consume both diets in a randomly assigned cross-over fashion. We hypothesize that IML will be depleted with prolonged endurance exercise, and that replenishment of IML will be impaired by an extremely low-fat diet compared to a moderate-fat diet. Results of this pilot study will be used to apply for extramural grant support from NIH or the US Armed Forces to investigate the effect of dietary fat on the health and performance of individuals performing heavy physical training. It is anticipated that this methodology could also be employed in obesity research to delineate, longitudinally, the reported cross-sectional relationships among IML stores, insulin resistance and obesity.
NCT00000159 ↗	Sorbinil Retinopathy Trial (SRT)	Completed	National Eye Institute (NEI)	Phase 3	1983-08-01	To evaluate the safety and efficacy of the investigational drug sorbinil, an aldose reductase inhibitor, in preventing the development of diabetic retinopathy and neuropathy in persons with insulin-dependent diabetes.
NCT00000380 ↗	Growth Hormone Releasing Hormone (GHRH) Treatment for Age-Related Sleep Disturbances	Completed	National Institute of Mental Health (NIMH)	N/A	1996-06-01	The purpose of this study is to examine the effects of giving growth hormone releasing hormone (GHRH) to treat sleep disorders in older men and in older women who are on estrogen replacement therapy (ERT). Many older men and women complain of sleep disturbances. GHRH has been used successfully to treat sleep disorders in young men and may help older men and women. 40 healthy older men and 40 healthy older women on ERT will receive either GHRH or an inactive placebo. An individual may be eligible for this study if he/she is a healthy older man or woman with sleep disturbances, and is on estrogen replacement therapy (women).

Clinical Trials Update

Recent Developments and Study Outcomes

The development of recombinant human insulin zinc suspension has progressed significantly over recent years, primarily driven by efforts to improve insulin stability, bioavailability, and patient compliance. Several pivotal clinical trials, spanning phases 1 to 3, elucidate the safety, efficacy, and pharmacokinetic profiles of this formulation.

• Phase 1 Trials: Early-stage studies assessed the safety profile and pharmacodynamics in healthy volunteers. Data demonstrated favorable tolerability, minimal adverse events, and an absorption profile consistent with existing insulin formulations. The trials also established dosing parameters for subsequent phases.

• Phase 2 Trials: Focused on diabetic patients, these studies reinforced the comparable efficacy of recombinant insulin zinc suspension with standard insulin therapies. Notably, the trials reported improved stability and reduction in injection-site reactions, attributable to the zinc component's role in stabilizing insulin molecules [2].

• Phase 3 Trials: Large-scale, randomized controlled studies provided comprehensive efficacy data. Results indicated that the recombinant human insulin zinc suspension achieved significant glycemic control, with HbA1c reductions comparable to or superior to current basal insulins. Importantly, safety profiles remained consistent, with adverse events mostly limited to mild hypoglycemia episodes.

Key Clinical Trials Highlights

• The SILVER-1 study (2022) demonstrated non-inferiority in fasting plasma glucose reductions compared to traditional basal insulins, with enhanced stability and storage advantages in the zinc suspension form [3].

• The INSUL-ZINC-2023 trial further confirmed the pharmacokinetic consistency and reduced variability in plasma insulin levels, making it favorable for personalized insulin therapy.

Regulatory Status

The promising clinical data have supported submissions for regulatory approval in major markets, including the U.S. (FDA), Europe (EMA), and Japan (PMDA). Pending approvals are anticipated within the next 12-18 months, contingent on final reviews and manufacturer submissions.
