Hyperosmolar hyperglycaemic state higher among type 1 diabetes patients compared to type 2 diabetes patients

Hyperosmolar hyperglycaemic state is  higher among patients with type 1 diabetes compared with type 2 diabetes suggests a new study published in the Diabetes Care

The hyperosmolar hyperglycemic state (HHS) is a rare and life-threatening complication of diabetes. We aimed to estimate the incidence of HHS and describe the clinical and biomarker profiles of patients with HHS, including subgroups with acidosis and acute kidney injury.

This nationwide, descriptive cohort study used Danish registry data during years 2016–2018 to identify acutely admitted patients fulfilling the hyperglycemia and hyperosmolarity criteria of HHS (glucose ≥33 mmol/L and osmolarity [2 × sodium + glucose] ≥320 mmol/L).

RESULTS

They identified 634 patients (median age, 69 years (first quartile; third quartile: 58; 79) who met the criteria of HHS among 4.80 million inhabitants aged ≥18 years. The incidence rates were 16.5 and 3.9 per 10,000 person-years among people with known type 1 (n = 24,196) and type 2 (n = 251,357) diabetes, respectively. Thirty-two percent of patients with HHS were not previously diagnosed with diabetes. Patients were categorized as pure HHS (n = 394) and combined HHS and diabetic ketoacidosis (HHS-DKA; n = 240). The in-hospital mortality rate for pure HHS was 17% and 9% for HHS-DKA.

The incidence of HHS was higher among patients with type 1 diabetes compared with type 2 diabetes. HHS is a spectrum of hyperglycemic crises and can be divided in pure HHS and HHS-DKA. In one-third of patients, HHS was the debut of their diabetes diagnosis.

Breakthrough Treatment with finerenone for Advanced Kidney Disease and Diabetes Cost-Effective

In the Netherlands, where the healthcare system grapples with the staggering burden of over one million patients combating type 2 diabetes (T2D), a significant breakthrough has emerged. A study evaluating the cost-effectiveness of integrating finerenone, a promising therapeutic addition to standard care, offers hope for patients with advanced chronic kidney disease (CKD) and T2D. The study results were published in the journal Cardiovascular Diabetology. 

T2D often brings along the ominous companion of CKD, affecting approximately 36% of patients in the Netherlands. The annual medical costs associated with T2D and CKD are a considerable financial strain, totaling around €1.3 billion and €805 million, respectively. The FIDELIO-DKD trial, a landmark investigation, showcased that the inclusion of finerenone in the standard of care (SoC) regimen significantly reduces the risk of CKD progression and cardiovascular (CV) events in patients dealing with CKD stages 2–4 linked to T2D.

To delve deeper into the potential impact of finerenone on healthcare economics, the study employed the validated FINE-CKD model. This Markov cohort model simulates the lifelong journey of patients, focusing on outcomes related to CV events and renal replacement therapy. The researchers tailored the model to reflect the Dutch societal perspective, considering both clinical effectiveness and economic implications.

Findings: 

  • Results from the study paint a promising picture. When finerenone is integrated into the SoC, patients experience an extension in the time free from CV events and renal replacement therapy, translating to 0.20 additional quality-adjusted life years (QALYs).
  • Perhaps even more compelling is the cost-saving aspect: finerenone led to a €6136 decrease in total lifetime costs per patient compared to SoC alone.
  • This financial benefit stems from the significant reduction in renal and CV events, showcasing finerenone as a dominant treatment option.
  • The study found that finerenone, when added to SoC, has an 83% probability of being a dominant strategy and a 93% probability of being cost-effective, particularly at a willingness-to-pay threshold of €20,000.

The implications of this study are groundbreaking, not just for patients facing the challenging intersection of T2D and advanced CKD but also for the broader healthcare system. By demonstrating that the integration of finerenone not only improves patient outcomes but also yields substantial cost savings, this research paves the way for more widespread adoption of this innovative treatment approach. In essence, the study offers a glimmer of hope for those navigating the complexities of diabetes and advanced kidney disease, showcasing that cutting-edge treatments can not only enhance lives but also contribute to the economic sustainability of healthcare systems.

SGLT2 inhibitors may slow progression of diabetic retinopathy: JAMA

SGLT2 inhibitors may lower risk of diabetic nephropathy and cut progression of diabetic retinopathy suggests a new study published in the JAMA.

Diabetic nephropathy and diabetic retinopathy share many similarities in pathophysiological processes. Preclinical studies have shown that sodium-glucose cotransporter 2 inhibitors (SGLT2is) have a protective role in the risk of diabetic retinopathy.

A study was done to compare the risk of sight-threatening retinopathy associated with SGLT2is and other second-line glucose-lowering medications (including pioglitazone, sulfonylureas, and dipeptidyl peptidase-4 inhibitors [DPP-4is]) in patients with type 2 diabetes (T2D).

This cohort study in Taiwan applied a new-user and active-comparator design. Patient demographic and clinical data were obtained from the National Health Insurance Research Database. Adult patients with newly diagnosed T2D from January 1, 2009, to December 31, 2019, were recruited and followed up until December 31, 2020. Propensity score matching was used to identify pairs of patients treated with SGLT2i vs DPP-4i, SGLT2i vs pioglitazone, and SGLT2i vs sulfonylurea from January 1, 2016, to December 31, 2019. Data were analyzed between August 18, 2022, and May 5, 2023.

The main outcome was sight-threatening retinopathy in participants. Cox proportional hazards regression models were used to assess relative hazards of sight-threatening retinopathy between the matched case and control groups.

Results

A total of 3 544 383 patients with newly diagnosed T2D were identified. After 1:1 propensity score matching, 65 930 pairs of patients treated with SGLT2i vs DPP-4i, 93 760 pairs treated with SGLT2i vs pioglitazone, and 42 121 pairs treated with SGLT2i vs sulfonylurea were identified. These matched patients included 236 574 males (58.6%), with a mean (SD) age of 56.9 (11.8) years. In the matched cohorts, SGLT2i had a significantly lower risk of sight-threatening retinopathy than DPP-4i (adjusted hazard ratio [AHR], 0.57; 95% CI, 0.51-0.63), pioglitazone (AHR, 0.75; 95% CI, 0.69-0.81), and sulfonylureas (AHR, 0.62; 95% CI, 0.53-0.71). The Kaplan-Meier curves showed that SGLT2i was associated with a significantly lower cumulative incidence of sight-threatening retinopathy than DPP-4i (3.52 vs 6.13; P < .001), pioglitazone (4.32 vs 5.76; P < .001), and sulfonylureas (2.94 vs 4.67; P < .001).

This cohort study found that SGLT2i was associated with a lower risk of sight-threatening retinopathy compared with DPP-4i, pioglitazone, and sulfonylureas. This finding suggests that SGLT2i may play a role not only in reduced risk of diabetic nephropathy but also in the slow progression of diabetic retinopathy in patients with T2D.

Add on esketamine to propofol sedation may reduce hypotension in patients undergoing same-visit bidirectional endoscopy

A recent double-blind, placebo-controlled randomized clinical trial conducted across three teaching hospitals in China evaluated the efficacy of low-dose esketamine as an adjuvant to propofol-based sedation during same-visit bidirectional endoscopy. The study aimed to explore whether the addition of esketamine could potentially reduce the occurrence of adverse events such as desaturation and hypotension.

This study was published in the journal JAMA Network Open by Nan Song and colleagues. The trial enrolled 663 patients scheduled for same-visit bidirectional endoscopy and randomized them to receive either esketamine or a placebo. After initial sedation induction with sufentanil and propofol, the esketamine group received intravenous esketamine while the placebo group received an equivalent volume of saline. The primary outcome assessed was the composite of desaturation and hypotension during the procedures.

Out of the initially enrolled 663 patients, 660 completed the study, with the median age of participants being 48 years. The administration of esketamine demonstrated significant benefits:

  • Reduced Incidence of Adverse Events: Esketamine notably decreased the composite outcome of desaturation and hypotension during the procedures compared to the placebo group (8.2% vs. 21.0%). This represented a substantial reduction of approximately 61% in the incidence of these adverse events (odds ratio [OR], 0.34; 95% CI, 0.21-0.54; P < .001).

  • Lower Incidences of Desaturation and Hypotension: Esketamine administration led to significantly lower incidences of desaturation (OR, 0.36; 95% CI, 0.18-0.72; q = .01) and hypotension (OR, 0.33; 95% CI, 0.18-0.60; q < .001).

  • Reduced Propofol Requirements: Additionally, patients receiving esketamine required substantially lower amounts of propofol compared to the placebo group (difference, −58.9 mg; 95% CI, −65.7 to −52.2 mg; q < .001).

The findings of this trial strongly advocate for the utilization of low-dose esketamine as an adjunct to propofol-based sedation in endoscopic procedures. The remarkable reduction in the incidence of adverse events, particularly desaturation and hypotension, along with decreased propofol requirements, underscores the potential of esketamine in enhancing the safety profile of endoscopic sedation.

The promising outcomes of this study suggest that esketamine could be a valuable addition to the sedation regimen for endoscopic procedures, offering improved patient safety and potentially enhancing the overall experience for individuals undergoing such interventions.

Light therapy improves sleep and psychobehavioural symptoms in patients with Alzheimer’s disease: Study

China: Light therapy significantly improves sleep and psychobehavioral symptoms and leads to relatively fewer side effects in patients with Alzheimer’s disease, a recent study published in PLOS One has revealed. 

The cognitive decline associated with Alzheimer’s disease is often accompanied by sleep disturbances and psycho-behavioral symptoms including apathetic and depressive behavior, agitation and aggression. Photobiomodulation is a non-pharmacological therapy that uses light energy to stimulate the suprachiasmic nucleus (SCN), a sleep modulator in the brain. Despite light therapy receiving increased attention as a potential intervention for Alzheimer’s, a systematic evaluation of its efficacy and safety has been unavailable.

In the new study, Qinghui Meng of Weifang Medical University, China, and colleagues searched multiple research databases to identify all randomized controlled trials related to light therapy intervention for Alzheimer’s disease or dementia. Fifteen high-quality trials with available methods and relevant outcomes were selected for further analysis. The included trials were written in English, published between 2005 and 2022, and performed in seven countries. They included a combined 598 patients.

The meta-analysis of all fifteen trials found that light therapy significantly improved sleep efficiency, increased interdaily stability (a measure of the strength of circadian rhythms), and reduced intradaily variability (a measure of how frequently someone transitions between rest and activity during the day). In patients with Alzheimer’s disease, light therapy also alleviated depression and reduced patient agitation and caregiver burden.

Given the limited sample sizes in studies included in this meta-analysis, the authors advocate for larger future studies, which could also explore if bright light exposure could cause any adverse behaviour in patients. They conclude that light therapy is a promising treatment option for some symptoms of Alzheimer’s disease.

The authors add: “Light therapy improves sleep and psycho-behavioural symptoms in patients with Alzheimer’s disease and has relatively few side effects, suggesting that it may be a promising treatment option for patients with Alzheimer’s disease.”

Study shows beneficial effect of moderate low-carbohydrate diet for adults with type 1 diabetes

Sweden: A recent study carried out at the University of Gothenburg has shown the advantages of a moderately low-carbohydrate diet for adults with type 1 diabetes over a traditional diet. The study published in The Lancet Regional Health – Europe is the largest of its kind to date. 

The researchers revealed that the average blood sugar level is reduced and the time with good values during 24 hours is increased, without any negative health impact. 

Participants were for different periods randomly assigned in a crossover manner to eat a traditional diet with 50% of the energy from carbohydrates, or a moderate low-carbohydrate diet with 30% of the energy from carbohydrates.

This is a moderate reduction in carbohydrates, with 24-hour monitoring of all participants via continuous glucose monitoring (CGM). Blood glucose levels were recorded at least every 15 minutes during the 16 weeks of the study, and were followed up by a dietitian and diabetes nurse.

The researchers emphasize that for safety reasons, major changes in carbohydrate intake in type 1 diabetes should always be made in consultation with the healthcare provider. Individuals should not make these dietary changes on their own, especially not for children with type 1 diabetes. The current study concerns only adults.

Several benefits of a moderate low-carbohydrate diet

The 50 participants all had type 1 diabetes with elevated mean glucose, long-term blood sugar, and injection therapy with insulin or an insulin pump. Half were women, half men. The average age was 48 years.

Both diets tested were healthy in terms of fat and carbohydrate quality. They included vegetables, fiber-rich carbohydrate sources, unsaturated fats, nuts, seeds and legumes, and were individualized by a dietitian.

Participants on a moderate low-carbohydrate diet were found to spend more time in what is known as the target range, the range within which people with type 1 diabetes should be in terms of glucose levels. The increase in time within the target range was an average of 68 minutes per day compared to the traditional diet, while the time with elevated values ​​was reduced by 85 minutes per day. Overall clinical important changes.

The first author of the study is Sofia Sterner Isaksson, a doctoral student at the Sahlgrenska Academy at the University of Gothenburg and a dietitian in the NU Hospital Group.

“The study shows that a moderate low-carbohydrate diet lowers the average blood sugar level and that more patients can keep their blood sugar within the target range, which is considered beneficial in reducing the risk of organ damage for people with type 1 diabetes,” she says.

No adverse effects of the diet

The researchers saw no evidence of adverse effects. Cholesterol and blood pressure levels were similar for both diets, and participants also felt a bit more satisfied with the moderate low-carbohydrate diet. It has been discussed whether a form of acids, ketones, can become too high when carbohydrates are reduced in type 1 diabetes, but these were also kept at reasonable levels.

“A moderate low-carbohydrate diet can be a good treatment option for adults with type 1 diabetes with elevated glucose levels. However, it is important that the diet is healthy with a particular focus on fat and carbohydrate quality, and that the amount of carbohydrates is not too low so it can be considered safe. Healthcare providers should therefore offer help and monitoring of the diet,” says Sofia Sterner Isaksson.

Responsible for the study is Marcus Lind, professor of diabetology at the University of Gothenburg and senior physician at the research units for diabetes at Sahlgrenska University Hospital and the NU Hospital Group.

“All patients should find the diet that suits them, in consultation with their healthcare professionals, but there has been a lack of sufficiently large studies randomizing participants to different experimental treatments of this kind. It is therefore important that we can present data showing that a moderate low-carbohydrate diet is effective and safe for adults with type 1 diabetes,” he says.

Topical Atropine safe and effective for Childhood Myopia Control, Reveals Landmark Study

A comprehensive study evaluating the extended outcomes of topical atropine eye drops for childhood myopia control has shed light on its long-term safety and efficacy. The prospective, double-masked observational study, stemming from the Atropine for the Treatment of Myopia (ATOM) 1 and ATOM2 randomized clinical trials, delved into the effects of short-term atropine use during childhood throughout 10 to 20 years. The study found that the use of short-term topical atropine eye drops did not alter the final refractive errors 10 to 20 years after treatment.  

The study results were published in the journal JAMA Ophthalmology. 

Clinical trials exploring the efficacy of topical atropine eye drops for childhood myopia control have revealed varied outcomes in short-term studies, lacking sufficient data on long-term safety or other critical outcomes. Hence, researchers conducted a study to report the long-term safety and outcomes of topical atropine for childhood myopia control.  

The study encompassed participants from the ATOM1 study (atropine 1% vs placebo; 1999 through 2003) and the ATOM2 study (atropine 0.01% vs 0.1% vs 0.5%; 2006 through 2012), with evaluations conducted in 2021 through 2022. The primary focus was on assessing the change in cycloplegic spherical equivalent (SE) with axial length (AL) and monitoring the incidence of ocular complications.

Results: 

  • The research team examined 71 participants from the ATOM1 study and 158 from the ATOM2 study, with baseline characteristics representative of the original cohorts.
  • The results demonstrated that, on long-term evaluation, short-term topical atropine use during childhood (ranging from 0.01% to 1.0% for 2 to 4 years) did not lead to significant differences in final refractive errors 10 to 20 years post-treatment.
  • In the ATOM1 participants, the refractive errors and axial lengths were comparable between the 1% atropine-treated group and the placebo group.
  • Similarly, in ATOM2 participants across varying atropine concentrations (0.01%, 0.1%, and 0.5%), there were no significant differences in the outcomes.

Crucially, the study also addressed safety concerns, revealing no increased incidence of treatment or myopia-related ocular complications in the 1% atropine-treated group compared to the placebo group. The findings have significant implications for the design of future clinical trials targeting childhood myopia control, emphasizing the need for further research to delve into the optimal duration and concentration of atropine for effective and safe outcomes. This landmark study provides valuable insights into the long-term implications of atropine use in childhood myopia management, paving the way for more informed approaches in addressing this prevalent vision concern.

Can one pause taking Ozempic to indulge in holiday festivities?

Weight loss is a biggest concern for all. An increasing number of people are choosing Ozempic as the latest solution for weight loss and now many of them are considering whether to pause the medication to more comfortably enjoy food-filled holiday festivities. But is that advisable and safe to do?

According to the U.S. Food and Drug Administration, Ozempic is a drug that improves blood sugar control in adults with Type 2 diabetes when used alongside diet and exercise. The most common side effects of this medication include nausea, vomiting, diarrhea, abdominal pain, and constipation. Despite these side effects, the medication has gained popularity due to the significant weight loss experienced by many on Ozempic.

However, experts are discovering that pausing the medication might potentially result in prolonged side effects.

In the following Q&A, UCLA Health Clinical Nutrition expert Mopelola Adeyemo, MD, MPH addresses some of the most common questions regarding taking Ozempic during the holiday season and stresses the importance of not skipping doses to indulge in excessive eating during this festive period.

Dr. Adeyemo says when people start Ozempic they may experience symptoms such as nausea, vomiting, diarrhea and constipation which may resolve as their body gets used to the medication. However, when you skip Ozempic, there is risk, on restarting the medication, you may experience these symptoms again. The concern is greater if you have skipped the medication for several weeks and restart at a higher dose.

Furthermore, depending on how long you have skipped your Ozempic you may need to start on a lower dose when restarting. If you are taking Ozempic for weight loss this could delay you achieving your weight loss goals. If you have skipped your Ozempic for two weeks or more, I would recommend discussing with your physician the plan for restarting.

It is important to get the adequate amount of nutrients your body needs while taking Ozempic. Thus, the food recommendations while taking Ozempic are the same we recommend for every adult, which is to maintain a healthy well-balanced diet. We continue to recommend a diet consisting of lean protein sources, whole grains, fruits, plenty of vegetables, low-fat dairy, and healthy fat sources such as olive oil and avocados, while limiting saturated fats. I would recommend limiting fatty foods as they can trigger symptoms of abdominal pain, nausea, and/or diarrhea in some individuals which mirrors potential side effects of Ozempic he added.

One of the ways that Ozempic promotes weight loss is by increasing the sensation of feeling full sooner after starting a meal in part by slowing the emptying of the stomach. Thus, eating in excess can cause symptoms of nausea and vomiting due to the slowed emptying of the stomach. That’s why, while taking Ozempic, it is important to practice mindful eating including paying attention to portion sizes or focusing on multiple small meals during the day, if needed.

For people taking Ozempic for Type 2 diabetes, pausing the medication may cause blood sugar to be uncontrolled during these times. This becomes even more concerning if you stop the medication so that you can overindulge in high-carbohydrate foods during the holidays which will increase your blood sugar even further. Amongst individuals with diabetes, sugar levels being severely elevated can lead to feeling very ill with severe nausea and vomiting, requiring hospitalization.

Further, frequent pausing and restarting your Ozempic might make it challenging for your physician to find a medication regimen to control your diabetes. If for any reason you are considering pausing a medication prescribed by your physician for your diabetes, such as Ozempic, it is important to discuss this with your physician before doing so.

The long-term risk to pausing and restarting Ozempic when used for weight loss solely is limited to potentially slowing weight loss results.

To limit overindulging during the holidays, focus on practicing mindful eating behaviors. Practice chewing slowly and putting your fork on the table after each bite, so you give yourself time to assess your fullness level while eating. Try to avoid distractions while eating such as looking at the TV or your phone – this will improve your awareness of how much you are eating. When there is an option, choose the smaller plate. This will help you with portion control – sometimes seeing less on your plate can help you crave less.

Lastly, remember to start the plate off right, by first filling at least half of your plate with non-starchy vegetables, which can be very filling, but often lower in calories and packed with many needed nutrients and vitamins. Then move on to the protein and whole grains.

He ended, If you begin to experience adverse symptoms due to pausing Ozempic, contact the physician who prescribed your Ozempic right away. If you experience uncontrollable abdominal pain, vomiting or diarrhea, or inability to keep water down, seek medical attention right away by going to your local emergency room or urgent ca

Exposure to phthalates found in many household products can lower women’s ability to conceive

USA: A recent study published in Environmental Health Perspectives has revealed a link between exposure to phthalates and a lower probability of getting pregnant, but not pregnancy loss. Phthalates are a group of plasticizing and solvent chemicals found in many household products such as shampoo, makeup, vinyl flooring, toys and medical devices.

The study also noted an association between preconception exposure to phthalates and changes in women’s reproductive hormones, as well as increased inflammation and oxidative stress.

“Phthalates are ubiquitous endocrine disruptors and we’re exposed to them every day,” says lead author Carrie Nobles, assistant professor of environmental health sciences in the School of Public Health and Health Sciences.

People are exposed primarily by ingesting food and liquid that has come in contact with products containing the chemicals, according to a Centers for Disease Control and Prevention fact sheet.

Nobles and team analyzed data from a “unique cohort” of women in the preconception time-to-pregnancy study known as EAGeR (Effects of Aspirin in Gestation and Reproduction), which evaluated the effect of low-dose aspirin on live-birth rates.

The study includes detailed information on 1,228 participants during six menstrual cycles when they are attempting to get pregnant.

The women who became pregnant were followed through pregnancy.

“We were able to look at some environmental exposures like phthalates and how that relates to how long it takes to get pregnant. There was detailed data for each menstrual cycle, so we had a good handle on the date of ovulation and the timing of pregnancy when that happened,” Nobles says.

The body breaks down phthalates into metabolites that are excreted in urine and can be analyzed.

The researchers measured 20 phthalate metabolites in urine samples taken when the participants enrolled in the study.

“We found there were three parent compounds that seem to be most strongly associated with taking longer to get pregnant, although we saw a general trend toward it taking longer to get pregnant across the phthalates we looked at,” Nobles says.

“As exposure got higher, we saw more and more of an effect.”

The researchers also looked at a global marker of inflammation, C-reactive protein, and found the women who had higher levels of phthalates exposure also had higher levels of inflammation and oxidative stress, which can lead to organ and tissue damage and ultimately to disease.

In addition, women who showed higher levels of phthalates had lower estradiol and higher follicle-stimulating hormone across the menstrual cycle, which play an important role in ovulation and the early establishment of pregnancy.

“This profile — estradiol staying low and follicle-stimulating hormone staying high — is actually something that we see in women who have ovarian insufficiency, which can happen with age as well as due to some other factors,” Nobles says.

“Ovulation just isn’t happening as well as it used to.”

While women can check consumer product labels and look for phthalate-free options, the ubiquitous nature of the chemicals makes it difficult for an individual to control their exposure.

In Europe, certain phthalates are banned or severely restricted in their use, but the U.S. has no formal prohibitions.

Nobles says the research findings add to the evidence that phthalate exposures harm women’s reproductive health and can be used to help inform policymaking.

“Maybe we want to think differently about our regulatory system and how we identify important exposures that are having adverse effects on whether people can get pregnant and have a healthy pregnancy,” Nobles says.

Synokem Pharmaceutical Gets CDSCO Panel Nod To study Antidiabetic FDC Drug

New Delhi: With the condition of including more government sites distributed geographically, Synokem Pharmaceutical has got approval from the Subject Expert Committee (SEC) functional under the Central Drug Standard Control Organisation (CDSCO) to conduct the Phase IV clinical trial of the fixed-dose combination of the antidiabetic drug Linagliptin plus Metformin Hydrochloride film-coated bilayered tablet.

This recommendation came after Synokem Pharmaceutical presented the Phase IV clinical trial protocol before the committee, in light of the condition mentioned in permission in Form CT-23 dated 24.04.2023.

Linagliptin is a medicine used to treat type 2 diabetes. Type 2 diabetes is a condition where the body does not make enough insulin, or the insulin that it makes does not work properly. This can cause high blood sugar levels (hyperglycemia).

Linagliptin is in a class of medications called dipeptidyl peptidase-4 (DPP-4) inhibitors. Linagliptin is an inhibitor of DPP-4, an enzyme that degrades the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP).

Metformin is an oral anti-diabetic drug in the biguanide class for the treatment of type 2 diabetes mellitus, in particular, in overweight and obese people and those with normal kidney function. Metformin is a medicine used to treat type 2 diabetes and gestational diabetes.

At the recent SEC meeting for Endocrinology and Metabolism held on 23 November 2023, the expert panel reviewed the Phase IV clinical trial protocol of the FDC antidiabetic drug Linagliptin plus Metformin Hydrochloride film-coated bilayered tablet presented by Synokem Pharmaceutical.

After detailed deliberation, the committee recommended a grant of permission to conduct the Phase IV clinical trial with the condition to include more government sites, which should be geographically distributed.

In addition, the expert panel suggested that the firm should submit the Phase IV clinical trial report to CDSCO for further review by the committee.
