e12520 Background: Ribociclib, a selective CDK4/6 inhibitor, in combination with an aromatase inhibitor (AI) is approved for the treatment of HR+/HER2- advanced breast cancer (aBC) (locally advanced or metastatic). Real-world evidence for the effectiveness, safety and tolerability of ribociclib + AI in routine clinical practice is needed to support its use. Methods: RIBANNA (CLEE011ADE03) is a non-interventional study running in Germany since October 2017 involving up to 3020 postmenopausal patients receiving ribociclib + AI, endocrine monotherapy (ET), or chemotherapy (CT) as first-line treatment for HR+/HER2- aBC, prescribed in line with German guidelines. Data are collected from clinical practice in all three cohorts. Further lines of treatment are documented to examine outcomes of sequential therapy. Results: 461 patients enrolled to October 9, 2018 (Table). First-line mean daily ribociclib dose was 382 mg including and 540 mg excluding dose interruptions; mean duration of exposure to ribociclib: 128 days. Ribociclib was given in combination with anastrozole (8%), exemestane (7%), and letrozole (83%); ET comprised a selective estrogen receptor degrader (25%), nonsteroidal AI (64%), steroidal AI (5%), and a selective estrogen receptor modulator (7%); CT included taxane-based monotherapy (30%) or combination therapy (27%), anthracycline-based combination therapy (5%), other monotherapy (23%) or other combination therapy (13%). Conclusions: Population characteristics from the RIBANNA study show a diverse group of patients from a real-world setting of ribociclib treatment. Baseline demographics and characteristics.

e13018 Background: International guidelines recommend a combination of CDK4/6 inhibitor and endocrine therapy (ET) as first line treatment for HR+, HER2- MBC. Results from MONALEESA-2 demonstrate improved progression free survival (PFS) with ribociclib (CDK4/6 inhibitor) and ET as compared to ET alone. Prior to Australia’s Pharmaceutical Benefits Scheme funding, ̃800 patients participated in the ribociclib Medicine Access Program (MAP) from May 2017 to June 2018. Methods: KARMA is a secondary data use, non-interventional study of Australian patients who received first line treatment with ribociclib and aromatase inhibitor (AI), obtained via a MAP, for HR+, HER2- MBC. The aim was to capture comprehensive patient and treatment data to reflect real world practice and outcomes. Direct comparisons were made with the ribociclib/letrozole cohort in MONALEESA-2 given that the eligibility criteria were similar for both studies. Results: Data from 160 patients at 17 sites was analysed with a median follow up of 36.5 months. Baseline characteristics are shown in the table. 63 of 160 (39%) patients remain on ribociclib/AI at time of analysis. 58% of patients had at least 1 dose reduction, with the majority (77%) requiring only a single dose reduction. The most common reasons for dose reductions were neutropenia (68%) and abnormal liver enzymes (17%). 16 of 160 (10%) discontinued treatment due to toxicity, including 1 patient with QTc prolongation > 600ms. There were no deaths due to toxicity. Median duration of treatment and PFS were 24.5 (95% CI 17.8-33.3) and 36.3 months (95% CI 29.9- NR) respectively, compared to 20.2 and 25.3 months in MONALEESA-2. Landmark PFS was 76% at 12 months, 67% at 18 months and 64% at 24 months. Conclusions: This is the first real world study of ribociclib and AI developed alongside a MAP. The combination treatment was well tolerated with similar rates of dose reductions (58% in both) and treatment discontinuation due to toxicity (10% vs 8%) when compared to MONALEESA-2. This real-world cohort achieved a superior PFS, potentially explained in part by a younger population with more favourable baseline disease characteristics, including fewer disease sites and higher rates of bone only metastases. It is encouraging to see drug tolerability and efficacy replicated in real world patients.[Table: see text]

e13053 Background: Breast cancer was the second most common malignant tumor diagnosed in 2018 worldwide, and the main cause of cancer death in women. In Mexico is the leading cause of cancer deaths, the most common molecular subtypes is HR+/HER2- (63%). The addition of iCDK 4/6 can enhance the benefit seen with endocrine therapy (ET) alone. In this work we will describe the experience in a “real world” model, of two tertiary-level hospitals in Mexico, with the use of iCDK 4/6 in a period of 3 years. Methods: Retrospective review of medical records of all consecutive pts with histological diagnosis of metastatic breast cancer HR+/HER2- and iCDK 4/6 treatment at our Institutions from July 2016 to January 2019. Clinical and pathological variables at diagnosis were recorded. Progression free survival was estimated using Kaplan-Meier method and survival distributions were compared using the Log-rank test. To assess association variables and progression we use Chi square. Results: 65 pts were treated, all with iCDK 4/6 in combination with ET, either aromatase inhibitor or irreversible estrogen receptor antagonist. 62 with palbociclib and 3 with ribociclib; Median age was 53 y/o (IQR 42-63), ECOG 0-1 (92.3%), 80% was metastatic recurrent disease, 92% of these patients received endocrine adjuvant treatment. Median estrogen receptor percentage was 90 (IQR 61-92), progesterone 50 (9-83), KI67 20 (10-30). The metastatic sites were bone (64.6%), liver (41.5%), nodal (33.8%), lung (21.5%), CNS (3.1%) and others (18.5%). 26 pts (40%) received iCDK 4/6 in the first line, 21 (32.3%) in the second line, and 27% in subsequent lines. Any grade of toxicity was presented in 44 pts (67.7%), Most common toxicities were neutropenia (63%), fatigue (16.9%), anemia (9.2%), grade 3-4 toxicities were presented in 21.5% and 17 pts (26.2%) required any dose adjustment. At the cut-off date, 28 pts (43.1%) had disease progression, median time to progression for the 65 pts was 10 months (1-84). OR for first line treatment vs subsequent lines was 0.14 (0.04-0.47, 95%, p = 0.001). OR for pulmonary metastases were 4.21 (1.15-15.31, 95%, p = 0.03), for other sites of metastasis were NS. Conclusions: Our outcomes suggest that the PFS is better when iCDK 4/6 are used as a first line treatment. Pulmonary metastases are may associated with poorly outcomes. In low- and middle-income countries, efforts should be focused on early therapy with iCDK 4/6.

e21072 Background: Penpulimab is a human IgG1 monoclonal antibody (mAb) directed against human programmed cell death-1 (PD-1). Penpulimab, with its unique binding epitope, was engineered to eliminate Fc-mediated effector function that compromises anti-tumor immune cell function, and to optimize receptor occupancy by improving duration of drug binding. As a promising multi-target tyrosine kinase inhibitor (TKI), anlotinib significantly improved overall survival in advanced NSCLC patients (pts) in the phase 3 trial ALTER0303. Antiangiogenesis therapy combined with PD-1/PD-L1 inhibitors has shown excellent efficacy in advanced NSCLC pts. This is the trial evaluating chemo-free combination of penpulimab plus anlotinib in treatment-naive advanced NSCLC pts regardless of PD-L1 expression (NCT03866980). Methods: Pts with previously untreated, stage IIIB/IIIC/IV non-squamous NSCLC without sensitizing mutation of the epidermal growth factor receptor (EGFR) gene or translocation of the anaplastic lymphoma kinase (ALK) gene were enrolled. Eligible pts received penpulimab 200mg Q3W in combination with anlotinib 12mg QD (2 weeks on 1 week off) until loss of clinical benefit or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). Secondary endpoints included ORR, disease control rate (DCR), duration of response (DoR) and overall survival. Results: As of January 13, 2021, 26 pts had received the combination therapy of penpulimab plus anlotinib (median age 59.5yrs [range 30-71], 76.9% male, 76.9% ECOG PS 1), with a median treatment duration of 3.5 months. Of 21 pts who have had at least one tumor assessment, the ORR was 57.1% (12 PRs) and DCR was 90.5% (12 PRs, 7 SDs). Median PFS has not been reached, and eleven responders remain in response. Treatment-related adverse events (TRAEs) occurred in 53.8% of pts (≥G3 TRAEs occurred in 15.4% [4/26]). Treatment-related SAEs occurred in 15.4% [4/26], and 7.7% of pts [2/26] had drug interruption or discontinuation due to TRAEs. Most common TRAEs (≥15%) were ALT increased, AST increased, hyperthyroidism and hypertension (15.4% each). Conclusions: The combination of penpulimab plus anlotinib as first-line treatment for locally advanced/metastatic NSCLC showed the promising efficacy with a manageable safety profile, thereby suggesting that this combination therapy may be a viable chemo-free treatment strategy for locally advanced/metastatic NSCLC pts. Clinical trial information: NCT03866980.
