The Safety of Ixekizumab in Chinese Adults with Moderate-to-Severe Plaque Psoriasis: Analyses from a Prospective, Single-Arm, Multicenter, 12-Week Observational Study.

Ixekizumab, a monoclonal antibody against interleukin-17A, is efficacious and well tolerated for the treatment of moderate-to-severe plaque psoriasis. However, there are limited data on the real-world safety of ixekizumab in Chinese patient populations. We performed an observational study of ixekizumab for the treatment of moderate-to-severe plaque psoriasis in routine clinical practice in China. Here we present a further safety analysis of this study. In this prospective, observational, single-arm, multicenter, post-marketing safety study, adults (≥18 years) with moderate-to-severe plaque psoriasis receiving ixekizumab were enroled at dermatology departments in hospitals across China and prospectively followed for 12 weeks or until their last dose of ixekizumab. In this analysis, we evaluated adverse events (AEs) of special interest (AESIs) identified using MedDRA® search strategies. We also analyzed AEs and AESIs occurring in greater than ten patients in subgroups by age (< 65/≥ 65 years), sex, body weight (< 60/60 kg to < 80/≥ 80 kg), renal impairment, hepatic impairment, history of tuberculosis, history of HBV infection, recent or active infection, history of allergic reaction/hypersensitivity, and number (0-1/2-4/5-7) of ixekizumab 80 mg injections after baseline until day 105. This analysis included 663/666 patients enrolled in the primary study. At least one AESI was reported in 224 (33.8%) patients and considered related to ixekizumab in 181 (27.3%); the most common were injection site reactions (n = 131, 19.8%), infections (n = 80,12.1%), and allergic reactions/hypersensitivity events (n = 59, 8.9%). The proportion of patients with ≥ 1 AE was higher for females versus males (99/186, 53.2% versus 184/477, 38.6%, p = 0.0006). The proportion of patients with ≥ 1 AE increased with the number of ixekizumab injections after baseline [61/188 (32.4%) for zero to one injection, 151/338 (44.7%) for two to four injections, and 61/106 (57.5%) for five to seven injections; p = 0.0001]. In this real-world study, ixekizumab was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis, with no difference in safety across most patient subgroups.

Safety and Effectiveness of Dulaglutide in the Treatment of Type 2 Diabetes Mellitus: A Korean Real-World Post-Marketing Study.

To investigate the real-world safety and effectiveness of dulaglutide in Korean adults with type 2 diabetes mellitus (T2DM). This was a real-world, prospective, non-interventional post-marketing safety study conducted from May 26, 2015 to May 25, 2021 at 85 Korean healthcare centers using electronic case data. Data on patients using dulaglutide 0.75 mg/0.5 mL or the dulaglutide 1.5 mg/0.5 mL single-use pens were collected and pooled. The primary objective was to report the frequency and proportion of adverse and serious adverse events that occurred. The secondary objective was to monitor the effectiveness of dulaglutide at 12 and 24 weeks by evaluating changes in glycosylated hemoglobin (HbA1c ), fasting plasma glucose, and body weight. Data were collected from 3,067 subjects, and 3,022 subjects who received ≥1 dose (of any strength) of dulaglutide were included in the safety analysis set (53% female, mean age 56 years; diabetes duration 11.2 years, mean HbA1c 8.8%). The number of adverse events reported was 819; of these, 68 (8.3%) were serious adverse events. One death was reported. Adverse events were mostly mild in severity; 60.81% of adverse events were considered related to dulaglutide. This study was completed by 72.73% (2,198/3,022) of subjects. At 12/24 weeks there were significant (P<0.0001) reductions from baseline in least-squares mean HbA1c (0.96%/0.95%), fasting blood glucose (26.24/24.43 mg/dL), and body weight (0.75/1.21 kg). Dulaglutide was generally well tolerated and effective in real-world Korean individuals with T2DM. The results from this study contribute to the body of evidence for dulaglutide use in this population.

Generating synthetic data from administrative health records for drug safety and effectiveness studies.

Administrative health records (AHRs) are used to conduct population-based post-market drug safety and comparative effectiveness studies to inform healthcare decision making. However, the cost of data extraction, and the challenges associated with privacy and securing approvals can make it challenging for researchers to conduct methodological research in a timely manner using real data. Generating synthetic AHRs that reasonably represent the real-world data are beneficial for developing analytic methods and training analysts to rapidly implement study protocols. We generated synthetic AHRs using two methods and compared these synthetic AHRs to real-world AHRs. We described the challenges associated with using synthetic AHRs for real-world study. The real-world AHRs comprised prescription drug records for individuals with healthcare insurance coverage in the Population Research Data Repository (PRDR) from Manitoba, Canada for the 10-year period from 2008 to 2017. Synthetic data were generated using the Observational Medical Dataset Simulator II (OSIM2) and a modification (ModOSIM). Synthetic and real-world data were described using frequencies and percentages. Agreement of prescription drug use measures in PRDR, OSIM2 and ModOSIM was estimated with the concordance coefficient. The PRDR cohort included 169,586,633 drug records and 1,395 drug types for 1,604,734 individuals. Synthetic data for 1,000,000 individuals were generated using OSIM2 and ModOSIM. Sex and age group distributions were similar in the real-world and synthetic AHRs. However, there were significant differences in the number of drug records and number of unique drugs per person for OSIM2 and ModOSIM when compared with PRDR. For the average number of days of drug use, concordance with the PRDR was 16% (95% confidence interval [CI]: 12%-19%) for OSIM2 and 88% (95% CI: 87%-90%) for ModOSIM. ModOSIM data were more similar to PRDR than OSIM2 data on many measures. Synthetic AHRs consistent with those found in real-world settings can be generated using ModOSIM. Synthetic data will benefit rapid implementation of methodological studies and data analyst training.

Post-marketing safety evaluation of recombinant anti-rho (D) immunoglobulin for the prevention of maternal rh-isoimmunization: A prospective, multi-centre, phase IV study

AntiD is a recombinant anti-D immunoglobulin approved as an immunoprophylaxis treatment in Rh-negative mothers carrying an Rh-positive fetus. This study was conducted to assess the safety and tolerability of AntiD in clinical settings. This was a prospective, multicenter, phase IV, post-marketing safety study of AntiD. The study was conducted at 29 hospitals in India as per regulatory requirements. Three hundred eligible Rh-negative women were administered a single intramuscular dose of either 150 mcg or 300 mcg AntiD within 72 hours of a sensitizing event as per the approved indication. Safety and tolerability were evaluated based on the assessment of adverse events (AEs) and serious adverse events (SAEs) reported during the study.Out of the 300 participants enrolled, 290 completed the study procedures. A total of 54 AEs and 34 treatment-emergent adverse events (TEAEs) were reported by 47 (15.7%) and 30 (10.0%) participants, respectively. Most reported TEAEs were mild, unrelated to the study drug, and were completely resolved during the study. Except for two participants with clinically significant hematological and urinalysis findings consistent with their underlying medical conditions, none of the participants exhibited abnormal clinical or laboratory parameters. Based on the assessment of the different safety parameters, AntiD administered at a dose of either 150 mcg or 300 mcg did not raise any new or significant safety concerns. The current study demonstrated that AntiD is well-tolerated and safe to use for anti-D prophylaxis as per product label indications for the prevention of Rh-isoimmunization in a clinical setting.

Safety and Effectiveness of Baricitinib in Chinese Patients with Moderate-to-Severe Rheumatoid Arthritis: 24-Week Results from a Post-Marketing Safety Study.

Baricitinib, a JAK1/JAK2 inhibitor, is approved for treatment of moderate-to-severe rheumatoid arthritis (RA) in China. This single-arm, prospective, multi-center, post-marketing safety study (PMSS) evaluated the safety and effectiveness of baricitinib in Chinese patients. This study included adult patients with moderate-to-severe active RA who received baricitinib over periods of approximately 12 and 24 weeks. The primary endpoint was safety, defined as week 12 adverse event (AE)/serious AE incidence. Secondary endpoints were week 24 safety and effectiveness (disease activity score with 28 joints/C-reactive protein [DAS28-CRP] and simplified/Clinical Disease Activity Index [SDAI/CDAI]). Safety analyses included 667 patients (female, 82.3%; mean age, 53.3years; mean RA duration, 86.9months); 106/667 (15.9%) were 65-74years old and 19/667 (2.8%) were ≥ 75years old; 87.0% received baricitinib 2mg QD. Total exposure was 262.1 patient-years (PY). At week 12, AEs had occurred in 214 (32.1%; exposure-adjusted incidence rate [EAIR], 172.5 per 100PY) patients (serious AEs: 22 [3.3%; EAIR, 15.0]). At week 24, AEs had occurred in 250 (37.5%; EAIR, 125.9) patients (serious AEs: 28 [4.2%; EAIR, 10.9]). Two patients (0.3%) died (of pneumonia and unknown cause); EAIR for death, 0.77. Serious infection occurred in 1.2% of patients (EAIR, 3.1). Hepatotoxicity occurred in 3.4% of patients (EAIR, 9.0). No patients met potential Hy's law laboratory criteria (alanine/aspartate aminotransferases ≥ 3 × upper limit of normal (ULN) and total bilirubin ≥ 2 × ULN). Malignancy occurred in one patient. No patients experienced venous thromboembolism (VTE) or major adverse cardiovascular events (MACE). At week 24, 52.4%, 27.5%, and 27.6% of patients achieved remission per DAS28-CRP, SDAI, and CDAI, respectively. This PMSS investigated the safety and effectiveness of baricitinib in clinical practice in China. No VTE/MACE or new safety signals were reported and there was promising effectiveness, supporting the use of baricitinib in Chinese patients with moderate-to-severe active RA.

Validation of an ICD-10 case-finding algorithm for endometrial cancer in US insurance claims.

To evaluate the positive predictive value (PPV) of an endometrial cancer case finding algorithm using International Classification of Disease 10th revision Clinical Modification (ICD-10-CM) diagnosis codes from US insurance claims for implementation in a planned post-marketing safety study. Two algorithm variants were evaluated. Provisional incident endometrial cancer cases were identified from 2016 through 2020 among women aged ≥50 years. One algorithm variant used diagnosis codes for malignant neoplasms of uterine sites (C54.x), excluding C54.2 (malignant neoplasm of myometrium); the other used only C54.1 (malignant neoplasm of endometrium). A random sample of medical records of recent incident provisional cases (2018-2020) was requested for adjudication. Confirmed cases showed biopsy evidence of endometrial cancer, documentation of cancer staging, or hysterectomy following diagnosis. We estimated the PPV of the variants with 95% confidence intervals (CI) excluding cases that had insufficient information. Of 294 provisional cases adjudicated, 85% were from outpatient settings (n = 249). Mean age at diagnosis was 69.3 years. Among the 294 adjudicated cases (identified with the broader algorithm variant), the same 223 were confirmed endometrial cancer cases by both algorithm variants. The PPV (95% CI) for the broader algorithm variant was 84.2% (79.2% and 88.3%), and for the variant using only C54.1 was 85.8% (80.9% and 89.8%). We developed and validated an algorithm using ICD-10-CM diagnosis codes to identify endometrial cancer cases in health insurance claims with a sufficiently high PPV to use in a planned post-marketing safety study.

The World of Vaccines: Phases of Clinical Trials and Current Status of COVID-19 Vaccines

The world of vaccines has transformed vaccination by saving millions of lives which otherwise would have killed many people and a hurdle for sustainable development world-wide. Indeed, the coronavirus disease 2019 (COVID-19) pandemic is a public health emergency and an important milestone that revealed how vaccines are really turning point for live changing across the world. Owing to extensive human efforts, vaccines for COVID-19 are discovered and developed and approved globally in less than a year, which is the first time in the history of the world of vaccines. Furthermore, one of the strategic goals of WHO’s ‘The Immunization Agenda 2030’ (IA2030) is the clinical development and approval of 500 new vaccines by 2030. Discovery of immunogens that elicit immune responses is a key step or process by which vaccine candidates have been optimized for further preclinical and clinical trials. Clinical evaluation is carried out in Phases (1-3) and is a sequential approach of establishing safety and efficacy in humans. Regulatory requirements for vaccine approval and licensure to bulk manufacturing are another hurdle. Further, post-marketing safety studies and post-marketing surveillance (Phase 4) are essential to collect the real-world data on safety and effectiveness of the approved vaccines. This review work provides a brief outline on timeline of development of traditional and COVID-19 vaccines and summarizes all the six stages of the vaccine development. Furthermore, current status of COVID-19 vaccines is discussed in view of future approvals.&#x0D;

Malignancy outcomes in patients with rheumatoid arthritis treated with abatacept and other disease-modifying antirheumatic drugs: Results from a 10-year international post-marketing study

ObjectiveTo evaluate the risk of malignancy (overall, breast, lung, and lymphoma) in patients with rheumatoid arthritis treated with abatacept, conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs), and other biologic/targeted synthetic (b/ts)DMARDs in clinical practice. MethodsFour international observational data sources were included: ARTIS (Sweden), RABBIT (Germany), FORWARD (USA), and BC (Canada). Crude incidence rates (IRs) per 1000 patient-years of exposure with 95% confidence intervals (CIs) for a malignancy event were calculated; rate ratios (RRs) were estimated and adjusted for demographics, comorbidities, and other potential confounders. RRs were then pooled in a random-effects model. ResultsAcross data sources, mean follow-up for patients treated with abatacept (n = 5182), csDMARDs (n = 73,755), and other b/tsDMARDs (n = 37,195) was 3.0–3.7, 2.9–6.2, and 3.1–4.7 years, respectively. IRs per 1000 patient-years for overall malignancy ranged from 7.6–11.4 (abatacept), 8.6–13.2 (csDMARDs), and 5.0–11.8 (other b/tsDMARDs). IRs ranged from: 0–4.4, 0–3.3, and 0–2.5 (breast cancer); 0.1–2.8, 0–3.7, and 0.2–2.9 (lung cancer); and 0–1.1, 0–0.9, and 0–0.6 (lymphoma), respectively, for the three treatment groups. The numbers of individual cancers (breast, lung, and lymphoma) in some registries were low; RRs were not available. There were a few cases of lymphoma in some of the registries; ARTIS observed an RR of 2.8 (95% CI 1.1–6.8) with abatacept versus csDMARDs. The pooled RRs (95% CIs) for overall malignancy with abatacept were 1.1 (0.8–1.5) versus csDMARDs and 1.0 (0.8–1.3) versus b/tsDMARDs. ConclusionsThis international, post-marketing observational safety study did not find any statistically significant increase in the risk of overall malignancies in pooled data in patients treated with abatacept compared with csDMARDs or with other b/tsDMARDs. Assessment of larger populations is needed to further evaluate the risks for individual cancers, especially lymphoma.

Post-Marketing Safety Study of Ramucirumab Plus FOLFIRI: Analysis of Age and Initial Dose of Irinotecan in Patients with Metastatic Colorectal Cancer.

There is limited real-world evidence regarding the safety of ramucirumab plus FOLFIRI in patients with metastatic colorectal cancer (mCRC). We evaluated the safety of ramucirumab plus FOLFIRI in patients with mCRC by age and initial dose of irinotecan. This single-arm, prospective, multicenter, non-interventional, observational study was conducted between December 2016 and April 2020. Patients were observed for 12months. Of 366 enrolled Japanese patients, 362 were eligible for study inclusion. The frequency of grade ≥3 adverse events (AEs) by age (≥75years vs <75years) was 56.1% versus 50.2%, indicating no substantial differences between age groups. Grade ≥3 notable AEs, including neutropenia, proteinuria, and hypertension, were also similar in both age groups, but the frequency of any grade venous thromboembolic events was higher in those aged ≥75years than in those aged <75years (7.0% vs 1.3%). The frequency of grade ≥3 AEs was slightly lower in patients receiving >150mg/m2 of irinotecan than in those receiving ≤150mg/m2 of irinotecan (42.1% vs 53.6%); however, the frequency of grade ≥3 diarrhea, but not any grade diarrhea, and liver failure/injury was higher in patients receiving >150mg/m2 of irinotecan than in those receiving ≤150mg/m2 of irinotecan (4.6% vs 1.9% and 9.1% vs 2.3%, respectively). The safety profile of ramucirumab plus FOLFIRI in mCRC patients was similar in subgroups by age and initial irinotecan dose in real-world settings.

Safety of concomitant administration of inactivated hepatitis A vaccine with other vaccines in children under 16years old in post-marketing surveillance.

Concomitant administration refers to the receipt of two or more vaccines during a single healthcare encounter, which is an efficient way to increase vaccination coverage in children. However, the post-marketing safety studies of concomitant administration are scarce. Inactivated hepatitis A vaccine (Healive®) has been used widely in China and other countries for more than a decade. We aimed to explore the safety of Healive® co-administered with other vaccines compared to Healive® alone in children under 16years old. We retrieved Adverse Events Following Immunization (AEFI) cases and vaccination doses of Healive® during 2020-2021 in Shanghai, China. The AEFI cases were divided into concomitant administration group and Healive® alone group. We used administrative data on vaccine doses as denominators to calculate and compare crude reporting rates between groups. We also compared baseline gender and age distribution, clinical diagnoses, and time interval from vaccination to onset of symptoms between groups. A total 319,247 doses of inactivated hepatitis A vaccine (Healive®) were used and 1,020 AEFI cases (319.50 per million doses) associated with Healive® were reported during 2020-2021 in Shanghai. There were 259,346 doses concomitantly administered with other vaccines and 830 AEFI cases (320.04 per million doses) were reported. There were 59,901 doses of Healive® that vaccinated alone, with 190 AEFI cases (317.19 per million doses). There was only one case with serious AEFI in concomitant administration group, with a rate of 0.39 per million doses. Reported rates of AEFI cases were similar between groups in general (p>0.05). Concomitant administration of inactivated hepatitis A vaccine (Healive®) with other vaccines has a similar safe profile as Healive® alone.

PARP inhibitor-related haemorrhages: What does the real-world study say?

PARP inhibitors (PARPis) are novel molecular targeted therapeutics for inhibition of DNA repair in tumor cells, which are commonly used in ovarian cancer. Recent case reports have indicated that haemorrhages-related adverse events may be associated with PARPis. However, little is known about the characteristics and signal strength factors of this kind of adverse event. A pharmacovigilance study from January 2004 to March 2022 based on the FDA adverse event reporting system (FAERS) database was conducted by adopting the proportional imbalance method based on the four algorithms, including the reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural networks (BCPNN) and multi-item gamma Poisson shrinker (MGPS). 725 cases of PARPi-haemorrhages-related adverse events were identified with a fatality rate of 4.72% (30/725) and a median age of 67 years. About 88% of the adverse events occurred within 6 months, and the median duration (IQR) was 68 days. Most adverse events (n=477, 75.11%) were related to the treatment of niraparib. Importantly, niraparib exposure was associated with a significant increase in haemorrhages-related adverse events (ROR (95% CI), 1.13(1.03,1.23), PRR (χ2), 1.12(7.32), IC (IC 025), 0.17(0.15). In addition, petechiae, gingival bleeding, bloody urine, as well as rectal haemorrhage should be monitored when using niraparib. Recognition and management of PARPi-haemorrhages-related adverse events is of significance to clinical practice. In this study, we provided a safety signal that haemorrhage-related adverse events should be monitored for when using niraparib. However, larger and more robust post-market safety studies are needed to improve the quality of this evidence.

A Case Study of Generalized Eczema Induced by Ginkgolide Injection

Objective: To analyze the clinical characteristics of adverse skin reactions (ADRs) caused by ginkgolide injection, and to provide reference for the post-marketing safety study of ginkgolide injection. Methods: By participating in the treatment of a patient with suspected adverse skin reactions caused by ginkgolide injection, The patient was given target ginkgolide injection 50mg intravenously once a day for two consecutive days due to cerebral infarction. Six days after drug withdrawal, the patient developed a rash on the buttocks, and then the rash quickly spread to the whole body, resulting in skin lesions with exudation tendency, itchy skin and extensive epidermal shedding. Combined with clinical medication and the clinical characteristics of this adverse reaction, the causes and mechanisms of adverse reactions caused by ginkgolide injection were analyzed from the ingredients of ginkgolide injection and the adverse reaction reports of ginkgolide extract. Consults: The adverse reaction was analyzed as severe skin allergy caused by ginkgolide injection. After oral administration of ebastine, injection of calcium gluconate and vitamin C, and topical dehumidification and itching-relieving ointment, the skin lesions basically healed after 2 weeks. Conclusions: Cases of skin allergic reactions caused by ginkgolide injection have been reported, but clinical trials on the safety of ginkgolide injection still lack the content of post-marketing safety studies. This adverse reaction is a detailed case analysis, in order to provide reference for the content of post-marketing safety of ginkgolide injection.

Clinical scenarios-based guide for tofacitinib in rheumatoid arthritis.

Tofacitinib was the first Janus kinase inhibitor to be approved for the treatment of rheumatoid arthritis (RA), and there is a large body of data to inform the efficacy and safety of this drug for patients at different places in their treatment journeys and with diverse demographics and characteristics. Here, we summarize tofacitinib clinical efficacy and safety data from some clinical trials, post hoc analyses, and real-world studies, which provide evidence of the efficacy of tofacitinib in treating patients with RA at various stages of their treatment journeys, and with differentiating baseline characteristics, such as age, gender, race, and body mass index. In addition, we review the safety data available from different patient subpopulations in the tofacitinib clinical development program, real-world data, and findings from the ORAL Surveillance post-marketing safety study that included patients aged ⩾50 years with pre-existing cardiovascular risk factors. The available efficacy and safety data in these subpopulations can enable better discussions between clinicians and patients to guide informed decision-making and individualized patient care.

A post-marketing safety study of ramucirumab with FOLFIRI in patients with metastatic colorectal cancer.

BackgroundRamucirumab [human vascular endothelial growth factor (VEGF) receptor-2 monoclonal antibody] + levofolinate, fluorouracil, and irinotecan (FOLFIRI) was approved for the treatment of metastatic colorectal cancer (CRC) in Japan based on the results from the phase 3 RAISE trial (NCT01183780). However, safety information of ramucirumab + FOLFIRI in the real-world setting is limited. Therefore, the present study was conducted to evaluate the safety of ramucirumab + FOLFIRI under routine clinical practice in patients with metastatic CRC (mCRC) after first-line chemotherapy.MethodsA single-arm, prospective, multicenter, non-interventional, observational study was conducted between August 2016 and May 2020. Patients with mCRC treated with ramucirumab + FOLFIRI for the first time were included. Patients were observed for 12 months from the start of ramucirumab. Data were recorded using the electronic data capture system.ResultsIn total, 362 patients with a mean age of 64.1 years were evaluated for safety, of whom 355 patients were evaluated for effectiveness. A higher proportion of the patients were males (n=200; 55.2%), had metastases and recurrent sites (n=362, 100.0%), and had received prior anti-cancer treatment (n=355; 98.1%). Approximately 83.7% (n=303) and 25.4% (n=92) of patients had medication history of bevacizumab and anti-epidermal growth factor receptor (EGFR) antibodies, respectively. Overall, 84.3% (n=305) of patients experienced any grade adverse events (AEs). Neutrophil count decreased (n=138; 38.1%), hypertension (n=58; 16.0%), and diarrhea (n=57; 15.7%) were observed frequently. The clinically relevant grade ≥3 AEs of special interest (AESIs) with >2% incidence included neutropenia (n=101; 27.9%), hypertension (n=35; 9.7%), proteinuria (n=23; 6.4%), hepatic dysfunction (n=15; 4.1%), febrile neutropenia (n=10; 2.8%), and leukopenia (n=9; 2.5%). The presence of renal disease at baseline increased the risk of proteinuria [risk ratio: 2.1; 95% confidence interval (CI): 1.1–4.2]. Three deaths were reported due to AEs, of which 1 was study treatment related. The 12-month survival rate of the ramucirumab + FOLFIRI regimen was 59%, mortality mainly (90%) occurring due to progressive disease.ConclusionsAlthough the current observational study enrolled patients with various medication history, the regimen of ramucirumab + FOLFIRI was manageable under clinical practice. No new safety concerns beyond the findings observed in previous clinical trials were reported.

Safety and effectiveness of ramucirumab and docetaxel: a single-arm, prospective, multicenter, non-interventional, observational, post-marketing safety study of NSCLC in Japan

ABSTRACT Background This study evaluated the safety and effectiveness of ramucirumab and docetaxel for non-small cell lung cancer (NSCLC) in real-world settings. Research Design and Methods This single-arm, prospective, multicenter, non-interventional, post-marketing study was conducted in Japan between August 2016 and January 2020. Patients diagnosed with unresectable advanced/recurrent NSCLC were eligible for study inclusion. Data on adverse events (AEs) and survival were collected electronically. Results Of 401 enrolled patients, 398 were eligible for study inclusion. Most patients were male (68.6%) with a median age of 67.0 years. Patients were predominantly diagnosed with adenocarcinoma (78.1%) or squamous cell carcinoma (16.6%); 46.2% received prior treatment with bevacizumab and 38.7% with immune-checkpoint inhibitors. AEs (any grade) were observed in 323 patients (81.2%; grade ≥ 3: n = 174, 43.7%). The most common AEs (any grade) were malaise (14.3%), decreased appetite (13.0%), and neutrophil count decrease (11.6%). At 12 months from treatment commencement, 93.2% of patients had discontinued, mostly due to progressive disease (53.4%) or AEs (28.3%). The 12-month survival rate was 56.7% (95% confidence interval: 51.5–61.8). Conclusions Data from real-world settings demonstrate ramucirumab and docetaxel treatment appears to be tolerable and effective in Japanese patients regardless of patient baseline characteristics and prior treatment.

A Novel Case Study of the Use of Real-World Evidence to Support the Registration of an Osteoporosis Product in China

On June 23, 2020, Prolia® (denosumab) was approved by the National Medical Products Administration (NMPA) in the People’s Republic of China as the first monoclonal antibody for the treatment of postmenopausal women with osteoporosis at high risk of fractures. Its brand name in Chinese is 普罗力, a transliteration from the English name “Prolia”, which has an implied meaning of “to give strength to everyone”— a suitable name for a potent anti-resorptive therapy. The approval was supported by a novel marketing authorization application (MAA) that included data from Prolia’s global clinical trial program establishing favorable efficacy and safety, augmented by results from a real-world evidence (RWE) study confirming the effectiveness and safety of Prolia in clinical practice within Taiwan and Hong Kong. Key constructs for this registration-quality RWE study included the fit-for-purpose assessment of data quality, methodology and quantitative assessment of potential biases, good practices of study conduct, and reproducibility of results. Using data from clinical practice in Taiwan and Hong Kong to evaluate the benefits versus risks of Prolia treatment in ethnic Chinese women with postmenopausal osteoporosis, the RWE study results for effectiveness were comparable to efficacy demonstrated in the global clinical trial program and results for safety were consistent with the incidence observed in global post-marketing safety studies. While RWE is often used to monitor postmarket safety of drug products, support health insurance coverage decisions, and inform clinicians on real-world use of medicines, it has not been widely used to support regulatory approval for new medicines in lieu of clinical bridging studies in countries where such studies are required. Well-conducted registrational RWE studies can play a pivotal role in complementing the totality of evidence presented in an MAA. The benefits of such an approach include avoiding the collection of additional placebo-controlled trial data in populations where adequate ethnic characterization of efficacy, effectiveness, and safety may already exist from postmarketing sources, and accelerate access for patients to innovative medicines in important regions. Here, we describe a regulatory case study of a novel MAA incorporating RWE that provided important evidence to confirm the benefit:risk of a new drug and facilitated a label expansion to a new patient population.
