Epidemiology of Children and Adolescents Psychiatric Disorders in Qazvin Central Areas 2016-2017 (A National Project)

Background Identification of children and adolescents mental health problems need to investigate of psychiatric disorders. Objective We aimed the prevalence of psychiatric disorders in central areas of Qazvin Province children and adolescent ages 6 to 18 years and their comorbidities. Methods This is a national project that will be implemented in central areas of Qazvin Province. This project will be focused on 1025 children and adolescents ages 6 to 18 years from central area of Qazvin province by cluster sampling method with Kiddie Schedule for Affective Disorders and Schizophrenia, Present and Lifetime version questionnaire (K-SADS-PL). The interview was conducted by 8 clinical psychologists Findings The prevalence of total psychiatric disorders in children and adolescents was 28.19% (95% CI=21.81-22.82) that was among boys 31.5% and among girls 25% and by comparing 95% of confidence interval of prevalence of psychiatric disorders in both genders. We saw a significant difference in total psychiatric disorder (P≤0.02) and results also showed that odds ratio (95% CI) for psychiatric disorders in the total population in terms of sex was 0.7 (for female). In addition, anxiety disorders had the most highlighted prevalence among all (13.2%) and; specific phobias disorders (4.7%) was the most common disorders .The results showed that the comorbidity of anxiety disorders and behavioral disorders is more than any others (22.2%). Free job mothers were valuable (P≤0.006). Conclusion This study showed the child and adolescents are significantly different in term of sex in central areas of Qazvin Province. Anxiety disorders are most common psychiatric disorders

KRYSTAL-1: Updated activity and safety of adagrasib (MRTX849) in patients (Pts) with unresectable or metastatic pancreatic cancer (PDAC) and other gastrointestinal (GI) tumors harboring a KRAS mutation

Background: KRAS, the most frequently mutated oncogene in cancer, is a key mediator of the RAS/MAPK signaling cascade that promotes cellular growth and proliferation. KRAS mutations occur in approximately 90% of pancreatic cancer, and approximately 2% of these are KRASG12C mutations. Adagrasib, an investigational agent, is a KRASG12Cinhibitor that irreversibly and selectively binds KRASG12C, locking it in its inactive state; adagrasib has been optimized for favorable pharmacokinetic (PK) properties, including long half-life (24 h), extensive tissue distribution, dose-dependent PK, as well as CNS penetration. Methods: KRYSTAL-1 (NCT03785249) is a multicohort Phase 1/2 study evaluating adagrasib as monotherapy or in combinations in pts with advanced solid tumors harboring a KRAS mutation. Here we report preliminary data from pts enrolled in a Phase 2 cohort evaluating single-agent adagrasib administered orally at 600 mg BID in previously treated pts with unresectable or metastatic solid tumors (excluding NSCLC and CRC), including pancreatic and other GI cancers. Study endpoints include clinical activity, safety, and PK. Results: The data cutoff was 10 September 2021. A total of 42 pts were enrolled in this cohort (median age 63.5 years, range 21-89; 52% female; 71% white; 29%/71% ECOG PS 0/1; median 2 prior lines of therapy, range 1-7; median follow-up 6.3 months), of whom 30 pts had KRASG12C-mutant GI tumors (12 PDAC, 8 biliary tract, 5 appendiceal, 2 gastro-esophageal junction, 2 small bowel, and 1 esophageal). In a preliminary analysis, 27 pts with GI tumors were evaluable for clinical activity; partial responses (PRs) were seen in 41% (11/27, including 3 unconfirmed PRs); the disease control rate (DCR) was 100% (27/27). Of the 12 pts with PDAC (median 3 prior lines of therapy; median follow-up 8.1 months), 10 were evaluable for clinical activity; PRs were seen in 50% (5/10, including 1 unconfirmed PR); the DCR was 100% (10/10). Median progression-free survival (PFS) was 6.6 months (95% CI 1.0-9.7), and treatment was ongoing in 50% of pts with PDAC. Among the 17 evaluable pts with other GI tumors, 6 achieved PR (35%; 2 unconfirmed) with a DCR of 100% (17/17); 11 pts were still receiving treatment. In the overall cohort, treatment-related adverse events of any grade occurred in 91% (38/42), the most frequent being nausea (48%), diarrhea (43%), vomiting (43%), and fatigue (29%); grade 3/4 events occurred in 21% of pts, with no grade 5 events. Conclusions: Adagrasib monotherapy is well tolerated and demonstrates encouraging clinical activity in pretreated pts with PDAC and other GI tumors harboring a KRASG12Cmutation. Further exploration of adagrasib is ongoing in this pt population (NCT03785249)
