e18548 Background: Generic imatinib therapy is being globally considered due to cost considerations. Evidence about its efficacy and safety in developing country settings, however, is scarce. Methods: The efficacy and safety of generic imatinib among Jordanian patients diagnosed with chronic myeloid leukemia (CML) was assessed utilizing an observational, multicenter, prospective study design. All patients (N = 91) were adults with CML treated with generic imatinib, mainly 400 mg/day, who either received generic imatinib (n = 33) as first-line therapy “first-line patients “or switched from patented imatinib to generic imatinib “switched patients” (n = 58). The primary objective was to measure proportions (95% Confidence Interval (CI)) of optimal response for first-line and switched patients at 12 months of treatment with generic imatinib, as defined in the 2009 ELN guidelines (CCyR [no Ph+ metaphases], or MMR [a ratio of BCR-ABL1 to ABL1 ≤0.1% on the International Scale]) and assessed by complete blood counts, fluorescence in situ hybridization and real-time quantitative PCR. Results: A total of 84.8% (n = 28/33) of the first-line patients achieved complete hematologic response (CHR) within 3 months of starting generic imatinib therapy (100% after 6 months). Out of the 23 evaluable first-line patients, [(87%, 95% CI = 73% - 100%), (n = 20)] in the per-protocol population (60.6 %, 95% CI = 51% - 86%) of the 33 patients in the intention-to-treat (ITT) population) achieved an optimal response at 12 months. All 58 switched patients had CHR at enrollment. Out of the 55 evaluable switched patients, [(96.4%, 95% CI = 91%-100%), (n = 53)] in the PP population (91.4%, 95% CI = 83%-98%) of the 58 patients in the ITT population) gained or maintained an optimal response at 12 months after switching to generic imatinib therapy. Most (84.7%, n = 144 out of 170) adverse events (AEs) were mild. Frequencies of drug-related AEs were similar to patented imatinib. Conclusions: Efficacy and safety of generic imatinib among middle eastern population in routine clinical practice is comparable to that of patented imatinib, and to that of the global population. Clinical trial information: NCT02977312.

Background There is scant data from India on efficacy and safety of palbociclib and ribociclib in routine clinical practice. Methods This retrospective, observational, single institution study included patients with estrogen and/or progesterone receptor positive and human epidermal growth factor receptor 2 (HER2) negative metastatic breast cancers, who received palbociclib or ribociclib with any partner endocrine therapy in any line of treatment between January 2016 and June 2019. Data were analyzed for progression-free survival (PFS), overall survival (OS) and toxicity. Results The study included 101 female patients with median age of 57 (IQR 48–62) years, of whom 80 (79.2%) were postmenopausal, 79 (78.2%) received palbociclib or ribociclib in second- or later-line treatment, 59 (58.4%) received fulvestrant and 41 (40.6%) received an aromatase inhibitor. In first-line treatment, at a median follow-up of 21.7 (0.5–41.9) months, median PFS and OS were 21.1 (95%CI 16.36-not estimable) months and not reached, respectively. In second- or later-line setting, at a median follow-up of 17.2 (0.5–43.7) months, median PFS and OS were 5.98 (95%CI 4.96–7.89) months and 20.2 (95%CI 14.1-not estimable) months, respectively. Grade 3–4 neutropenia and febrile neutropenia were seen in 45 (45.0%) and 9 (9.0%) patients, respectively while dose reduction was required in 32 (31.7%) patients. In multivariable Cox regression analysis, first-line setting (HR 0.49, 95%CI 0.25–0.97, p = 0.043) and ECOG performance status 1 (HR 0.43, 95%CI 0.20–0.91, p = 0.028) were significantly associated with PFS while only ECOG PS 1 was significantly associated (HR 0.04, 95%CI 0.008–0.206, p = 0.000) with OS. Conclusion Palbociclib and ribociclib, when used in routine clinical practice in first or subsequent lines of treatment, resulted in efficacy and toxicity outcomes in concordance with those expected from pivotal trials.

Tobacco smoking remains the single most preventable cause of morbidity and mortality in developed countries and poses a significant threat across developing countries where tobacco use prevalence is increasing. Nicotine dependence is a chronic disease often requiring multiple attempts to quit; repeated interventions with pharmacotherapeutic aids have become more popular as part of cessation therapies. First-line medications of known efficacy in the general population include varenicline tartrate, bupropion hydrochloride, nicotine replacement therapy products, or a combination thereof. However, less is known about the use of these products in marginalized groups such as the indigenous, those with mental illnesses, youth, and pregnant or breastfeeding women. Despite the efficacy and safety of these first line pharmacotherapies, many smokers continue to relapse and alternative pharmacotherapies and cessation options are required. Thus, the aim of this review is to summarize the existing and developing pharmacotherapeutic and other options for smoking cessation, to identify gaps in current clinical practice, and to provide recommendations for future evaluations and research.

e16161 Background: Docetaxel is standard of care for the treatment of HRPC, based on two large randomized clinical trials. The aim of this study was to determine if docetaxel use and effectiveness in routine clinical practice was similar to that seen in the TAX 327 randomized phase III clinical trial. Methods: A retrospective chart review was undertaken to assess patterns of docetaxel use for HRPC at our institution for the 2-year period since its approval for the first-line treatment of HRPC in 2005. Results: Eighty-eight patients, median age 71 and baseline PSA 107, received docetaxel in the first line setting. Main reasons for initiating docetaxel were rising PSA (90%) and progressive symptoms (71%). Eighteen percent of patients received docetaxel for rising PSA alone. A median of 7 cycles was administered. PSA response rates were 61%, time to response 1.5 months, and response duration 6.8 months. Disease progression was the most common reason for treatment discontinuation (36%). Main toxicities were fatigue (32%) and neuropathy (22%). Kaplan Meier survival analysis showed median duration of survival was 15.9 months (95% CI 12.4–20.5) from first drug use. 1-year survival was 0.63 (95% CI 0.52–0.72). Post-docetaxel, 36 patients received second-line treatment, mostly with mitoxantrone (89%). Second-line response rates were 22%, and median duration of response was 4 months. Conclusions: In routine clinical practice, docetaxel is a well-tolerated regimen for the treatment of HRPC. Response rates and toxicity profiles were comparable to the randomized trials. However, compared with the TAX 327 clinical trial, survival was slightly shorter than expected (15.9 vs. 18.9 months), possibly due to inclusion of patients with poorer performance status and comorbidities, who may be excluded from clinical trials. Second-line response rates were also comparable with previous reports. No significant financial relationships to disclose.
