Inclisiran sodium (Brand name: LEQVIO for s.c. injection syringe 300 mg, hereinafter referred to as inclisiran), a small interfering ribonucleic acid (siRNA) product that targets the mRNA that encodes the proprotein convertase subtilisin/kexin type 9 (PCSK9) protein was approved on September 25, 2023 for the indication of "Familial hypercholesterolemia, hypercholesterolemia" in Japan. Inclisiran is conjugated on the sense strand with triantennary N-acetylgalactosamine to facilitate uptake by hepatocytes. In vitro and in vivo pharmacology studies demonstrated the lowering effects of PCSK9 and LDL-C in hepatocytes and cynomolgus monkeys. It was considered unlikely to cause clinically significant risks due to toxicities arising from complementary binding to non-target RNA sequences (hybridization-dependent off-target effects). Clinical trials conducted globally including Japan in patients with familial hypercholesterolemia and hypercholesterolemia who did not reach the LDL-C target showed that inclisiran sodium 300 mg dosed at Day 1, Day 90 and then every 6 months demonstrated significant LDL-C reduction and the efficacy sustained long. The majority of patients achieved the guideline recommended LDL-C targets. Inclisiran sodium 300 mg was well tolerated and there were no specific safety concerns. Therefore, inclisiran is expected to be a new therapeutic option for the patients with familial hypercholesterolemia and hypercholesterolemia.

Review
[Pharmacological properties and clinical development overview of pertuzumab (genetical recombination), trastuzumab (genetical recombination) and vorhyaluronidase alfa (genetical recombination) (PHESGO combination for subcutaneous injection MA, IN)].
Pertuzumab and trastuzumab are anti-HER2 humanized monoclonal antibodies with different mechanisms of action. Their combination is expected to suppress intracellular HER2 signaling additively or synergistically. Their combination is widely recommended worldwide and has been established as a standard of care for HER2-positive breast cancer. However, improvement is required because of the prolonged time of intravenous infusion. Vorhyaluronidase alfa (rHuPH20) depolymerizes hyaluronan in the subcutaneous connective tissue. It's reported to increase the permeability and absorption levels of drugs. PHESGO combination for subcutaneous injection MA/IN (PHESGO) is a fixed-dose combination of pertuzumab, trastuzumab, and rHuPH20. A confirmatory phase III study (FeDeriCa) was conducted following a dose-finding phase I study (BO30185). Patients with HER2-positive early breast cancer were randomly assigned to receive either intravenous infusion of pertuzumab and trastuzumab or subcutaneous injection of PHESGO, in combination with chemotherapy, to compare the pharmacokinetics (PK), efficacy and safety. A phase II study (PHranceSCa) was also conducted to assess patients' preference and satisfaction. Based on these results, population PK analysis, and other data, PHESGO obtained marketing approval in Japan in September 2023 with indications for "HER2-positive breast cancer" and "advanced or recurrent HER2-positive colorectal cancer that has progressed following cancer chemotherapy and is not amenable to curative resection". By reducing the administration time, PHESGO is expected to contribute to various needs of patients and improvement of their daily lives. Since drug preparation is not required, it can provide convenience to healthcare professionals, leading to stress reduction of medical resources as well.

Randomized Controlled Trial Comparative Study
Excessive immune response and inflammation are associated with an increased risk of various diseases. In particular, excessive myeloperoxidase (MPO) activity in neutrophils causes inflammatory reactions and lifestyle-related diseases. Adlay has a long history of being used as a traditional Chinese medicine. Polyphenols present in adlay seeds are expected to have the effect of suppressing excessive immune and inflammatory responses. Here, we conducted a randomized, double-blind, parallel group, placebo-controlled study was conducted to evaluate the suppressing effects of adlay seeds extract on excessive immune responses. One hundred and twenty adults participated in the study and they were equally divided into an adlay tea intake group and a placebo group. MPO activity was significantly elevated in the placebo group after 8-wk ingestion, while no significant change was observed in the adlay group. Vascular endothelial functions improved in the adlay group, especially in subjects over 40 y old. These results indicate that adlay tea intake may suppress an excessive immune and inflammatory responses, and improve arterial stiffness. Since caffeic acid, p-coumaric acid, and ferulic acid detected in adlay tea are known to inhibit MPO activity, these polyphenols may be the major functional molecules. Collectively, adlay tea is considered to have a preventative effect against lifestyle-related diseases through improving vascular endothelial function by effects to maintain immune homeostasis of the contained polyphenols. This trial was registered at University Hospital Medical Information Network Clinical Trials Registry (UMIN000032263).

Effects of Milk Fat Globule Membrane Supplementation Following Exercise Training on Physical Performance in Healthy Young Adults: A Randomized Double-Blind, Placebo-Controlled Pilot Trial.
The purpose of this study was to examine whether 4 wk of daily ingestion of milk fat globule membrane (MFGM) combined with exercise training improves physical performance-muscle strength, agility and muscle power-in healthy young adults. The study was designed as a randomized, double-blind, and placebo-controlled trial. Twenty healthy young adults received either an MFGM powder containing 1.6 g of fat and 160 mg of sphingomyelin or an isocaloric placebo powder daily throughout 4 wk of power or agility training. Physical performance tests and body composition measurements were conducted before and after the 4-wk intervention. Ingestion of MFGM did not affect isometric or isokinetic muscle strength, but it was associated with a greater increase in vertical jump peak power compared with placebo. There were no significant changes in body weight or lean body mass during the intervention period in either group, and no significant differences between groups. We conclude that daily MFGM supplementation combined with exercise training has the potential to improve physical performance in young adults; however, further studies with larger sample sizes should be conducted to obtain more evidence supporting achievement of improved physical performance through MFGM supplementation.

Randomized Controlled Trial
Fibroblast growth factor-23 (FGF23) is a phosphaturic hormone secreted by osteocytes in response to dietary phosphate intake. An increase in FGF23 level is an indicator of excess phosphate intake relative to the residual nephron number. Therefore, avoiding excessive phosphate intake and inhibiting the elevation of serum FGF23 levels are important to preserve the number of functional nephrons. This randomized crossover trial aimed to determine the potential differences in the impacts on serum FGF23 levels between plant protein and animal protein-based meals in individuals with normal renal function. Nine young men were administered plant (no animal protein) or animal protein-based meals (70% of their protein was from animal sources) with the same phosphate content. The test meals consisted of breakfast, lunch, and dinner. Blood samples were collected in the morning, after overnight fasting, and before and after eating the test meals (for two consecutive days at the same hour each day). Furthermore, a 24-h urine sample was obtained on the day the test meal was consumed. No significant interactions were found among serum phosphate, calcium, and 1,25-dihydroxyvitamin D levels. However, after eating plant protein-based meals, serum FGF23 levels decreased and serum intact parathyroid hormone levels increased (interaction, p<0.05). Additionally, urine 24-h phosphate excretion tended to be lower in individuals consuming plant protein-based meals than in those consuming animal protein-based meals (p=0.06). In individuals with normal renal function, plant protein-based meals may prevent an increase in serum FGF23 levels and kidney damage caused by phosphate loading.

Randomized Controlled Trial
Alaska pollack protein (APP), has been reported as a protein source that can enhance muscle hypertrophy more than other protein sources in animal studies. This study aimed to examine the effects of APP ingestion on muscle quantity and quality in young adults. Fifty-five young college students were assigned to two groups: APP and placebo (whey protein: WP) groups, and instructed to ingest 4.5 g of each protein in addition to daily meals, and to maintain their usual daily physical activities for 3 mo. Twenty-one and 23 students completed the intervention and were analyzed in APP and WP groups, respectively. The maximum knee extension torque significantly increased in both groups during the intervention. The motor unit discharge rate, which is an indicator of activation, for a given force level significantly decreased in both groups during the intervention, but its decrease in the APP group was significantly greater than in the WP group. Echo intensity of the vastus lateralis evaluated by ultrasound images significantly decreased in both groups. The muscle thickness and skeletal muscle mass did not change. Small amount of additional APP intake induces greater effects on neural activation than WP, suggesting the greater neural economy of generation of force.

Randomized Controlled Trial
D-Allulose has blood glucose suppression effects in both animal and clinical studies. The mechanism mediating glucose suppression in animals is controlled by several actions including the inhibition of sucrase. To investigate the dose-response effects of D-allulose with a sucrose beverage on glucose tolerance and insulin levels using Thai volunteers. This was a prospective, randomized, double-blinded, crossover study. Subjects had five oral sucrose tolerance tests (OSTT) with escalating doses of D-allulose (0, 2.5, 5, 7.5 or 10 g) with a 50 g sucrose beverage in a random order once a week for five consecutive weeks. The five drinks were consumed in a random order; the order being blinded for both subjects and investigators. Blood samples were drawn immediately before consumption and at 30, 60, 90 and 120 min after consumption of the study product for measurement of plasma glucose and insulin levels. Thirty healthy subjects (11 men and 19 women) completed the study. The peak postprandial glucose (PePPG) and insulin levels (PePPI) were lower when D-allulose was added in a dose-dependent manner. The lowest plasma glucose and insulin levels occurred at 120 min after OSTT in all five products and they were raised when D-allulose was added in a dose-dependent manner. D-Allulose has a suppression response on glucose and insulin shown by the decrease in postprandial plasma glucose and insulin levels following the addition of D-allulose to sucrose in a dose-dependent manner. The more D-allulose added, the less marked the glucose and insulin response occurred.

Cancer-associated cachexia, a multifactorial syndrome involving loss of muscle mass and anorexia, affects the survival of cancer patients. Anamorelin was the first drug approved in Japan for the treatment of cachexia. However, cases in which anamorelin is discontinued within 3 weeks are often observed in clinical practice. This study aimed to explore the factors associated with continued anamorelin dosing. We retrospectively reviewed records of patients with lung, gastric, pancreatic, and colorectal cancer who started anamorelin at Fukuoka University Hospital from April 2021 to November 2022. Patients were divided into two groups based on the duration of anamorelin administration: 15 patients were classified into the <3 weeks group and 22 were classified into the ≥3 weeks group. The primary objective was to explore the potential factors associated with the continuation of anamorelin, and the secondary objectives were to compare survival and nutritional indices. In the univariate analysis, there were significant differences between the two groups in terms of cancer type (p=0.007) and serum albumin level (p=0.026). In the multivariate analysis, gastric cancer and albumin 2.7 g/dL or less were associated with the continuation of anamorelin. Survival was significantly shorter in the <3 weeks group (p=0.019). This study suggests that the continuation of anamorelin may be influenced by specific tumor types and serum albumin levels. Furthermore, the duration of anamorelin administration may affect patient survival.

An overwhelming surge of information regarding preparedness for postvaccination side effects had caused widespread confusion approximately since April 2021, when the coronavirus disease 2019 (COVID-19) vaccination had started for the general population in Japan. Notably, this resulted in a remarkably increased shortage of OTC acetaminophen formulations. The aim of this study was to elucidate the actual responses of the public in such an environment, how individuals acquired and understood information related to the management of postvaccination side effects, and how they obtained and used antipyretic analgesics before and after COVID-19 vaccination. We conducted a web-based survey in January 2022, targeting 400 individuals aged ≥20 years, who had received two COVID-19 vaccine doses, and excluded qualified professionals such as physicians and pharmacists. The results revealed that 67% of the respondents had obtained antipyretic analgesics in anticipation of adverse effects after vaccination, whereas 38% had taken these medicines before and/or after the second vaccination. Possible misappropriation of medicines from others, preventive administration, and lack of dosage and administration confirmation are the problems identified in medication acquisition and usage. Additionally, avoidance of antipyretic analgesics based on information without scientific evidence was observed. This study revealed no small amount of inappropriate use of medicines in situations, such as the COVID-19 pandemic, where there is an "infodemic" of mixed-quality information. Pharmacists, as experts in medication, should play a crucial role in promoting appropriate medication usage by consistently staying updated with the latest scientific evidence and proactively supporting OTC drug selection and counseling medication.

In Japan, influenza vaccination is offered to children and pregnant women at clinics or hospitals as an elective, self-funded treatment, as the vaccination is not included in the national vaccination subsidy program. However, some Japanese municipalities offer a discretionary subsidy for seasonal influenza vaccination of children and pregnant women as a local policy. We identified these local subsidy programs during 2019/2020 seasonal influenza season by conducting a cross-sectional survey across Japan. Out of a total of 1741 municipalities, responses were received from 1732; therefore, the response rate was 99.5%. The local influenza vaccine subsidy programs for children were offered in 45.7%, and for pregnant women in 10.2%, of Japanese municipalities. This is the first survey of subsidy programs for pregnant women. While policy diffusion of subsidy programs for children was observed during the 9 years since a previous study, such programs for pregnant women remain limited. Despite many municipalities having subsidy programs, we found that their provision still remains limited when viewed as a whole.
