Background Treatment-free survival (TFS) characterizes disease control after discontinuation of immune checkpoint inhibitors (ICIs) until subsequent therapy or death. We previously evaluated TFS in a pooled analysis the CheckMate 067 and 069 trials ICIs nivolumab ipilimumab, alone combination, patients with advanced melanoma minimum follow-up 36 months. This investigated differences between treatments 60 months, their relation to overall (OS) differences. Methods Data were from 937 who...

Abstract Purpose: Patients discontinuing immuno-oncology regimens may experience periods of disease control without need for ongoing anticancer therapy, but toxicity persist. We describe treatment-free survival (TFS), with and toxicity. Methods: Data were analyzed from the randomized phase III CheckMate 214 trial nivolumab plus ipilimumab (n = 550) versus sunitinib 546) treatment-naïve, advanced renal cell carcinoma (aRCC). TFS was estimated by 42-month restricted mean times defined area...

Abstract Low molecular weight heparins (LMWHs) and direct oral anticoagulants (DOACs) are among the recommended treatment options for cancer-associated thrombosis (CAT) in 2019 National Comprehensive Care Network guidelines. Little is known about current utilization of DOACs CAT patients, particularly on inpatient to outpatient therapy transition. This study assessed real-world patterns hospital/ED adult cancer patients (≥ 18 years) diagnosed with during a hospital visit IQVIA’s Hospital...

Abstract Background Recurrence-free survival (RFS) and overall (OS) data for adjuvant nivolumab versus placebo (proxy routine surveillance) in patients with high-risk, resected melanoma are lacking. This post hoc, indirect treatment comparison (ITC) used pooled from the phase 3 EORTC 18,071 (ipilimumab vs. placebo) CheckMate 238 (nivolumab ipilimumab) trials to assess RFS OS numbers needed treat (NNT) over 4 years. Methods Patients stage IIIB-C cutaneous (American Joint Committee on Cancer...

Abstract Purpose Patients with metastatic triple-negative breast cancer (mTNBC) have poor prognosis and limited treatment options. Sacituzumab govitecan (SG), a Trop-2–directed antibody–drug conjugate, is approved for patients mTNBC who received ≥ 2 systemic therapies (≥ 1 in the setting) based on ASCENT study (NCT02574455). The current describes real-world SG use outcomes United States. Methods This retrospective, observational included adult from ConcertAI Patient360™ database second line...

Purpose To evaluate treatment patterns in patients diagnosed with incident chronic myelogenous leukemia (CML) newly initiating therapy imatinib, dasatinib, or nilotinib. Patients were followed to determine switching and discontinuation rates. Factors associated from index TKI therapy, reasons for based on electronic chart notes, frequency of laboratory monitoring assessed during the follow-up period. Methods A retrospective cohort study was conducted aged ≥ 18 years who identified Kaiser...

305 Background: Nivolumab plus ipilimumab (NIVO+IPI), a first-in-class combination immunotherapy, was approved by the US Food and Drug Administration in April 2018 for treatment of intermediate- or poor-risk advanced renal cell carcinoma (RCC), paradigm has changed dramatically over past few years. This real-world study examined patterns sequences, response, safety, survival outcomes with this novel first-line (1L) therapy among patients diagnosed metastatic RCC (mRCC) community oncology...

Patients with advanced melanoma treated immune checkpoint inhibitors can experience ongoing disease control after treatment discontinuation without subsequent systemic anticancer therapy. We previously defined a novel outcome, treatment-free survival (TFS), as the time between protocol therapy cessation and initiation/death. assessed effect of established prognostic variables [lactate dehydrogenase (LDH), programmed death ligand 1 status, BRAF mutation performance sex] on TFS in different...

286 Background: RCC accounts for ~80%‒90% of all kidney cancers worldwide. The mRCC treatment landscape is rapidly changing with the approval new therapies; data describing real-world (RW) patterns and sequencing are limited. This study investigates characteristics, patterns, patients in RW (December 2015‒May 2020) post-dual immuno-oncology therapy (IO-IO) United States (April 2018‒May 2020).

4578 Background: Nivolumab in combination with cabozantinib (N+C) has demonstrated significantly improved progression-free survival (PFS), objective response rate (ORR), and overall (OS), compared sunitinib as a first-line (1L) treatment for aRCC the phase 3 CheckMate (CM) 9ER trial. As there are no head-to-head trials comparing N+C pembrolizumab axitinib (P+A), this study efficacy of P+A 1L aRCC.
