Abstract
INTRODUCTION Trilaciclib is a transient cyclin-dependent kinase 4/6 inhibitor that decreases the incidence of chemotherapy-induced myelosuppression in extensive-stage small cell lung cancer (ES-SCLC). TRACES study was designed to assess the safety, efficacy and pharmacokinetics (PK) of trilaciclib before chemotherapy in Chinese patients with ES-SCLC. METHODS The study included an open-label safety run-in part (Part 1) and double-blinded, placebo-controlled part (Part 2) where patients received trilaciclib or placebo before chemotherapy. Treatment-naïve or previously treated ES-SCLC patients received intravenous trilaciclib (240 mg/m2) or placebo before etoposide/carboplatin or topotecan, respectively. Primary endpoints were PK, safety and duration of severe neutropenia (DSN) in Cycle 1 in Part 1 and Part 2. Exploratory endpoints included the effect of trilaciclib on other myeloprotection endpoints, safety and antitumor efficacy. RESULTS Overall, 95 Chinese patients were enrolled, of which 12 and 83 patients were in Part 1 and Part 2, respectively. In Part 1, trilaciclib was well tolerated. Non-compartmental analysis results revealed no substantial differences in the main exposure parameters. In Part 2, 41 patients received trilaciclib, and 42 received placebo. Patients in trilaciclib arm vs placebo arm had a clinically and statistically significant decrease in DSN (mean [SD]) in Cycle 1 (0 [1.7] vs 2 [3.0] days; P = 0.0003), with improvements in additional neutrophil, red blood cell, and platelet measures. After a median follow-up of 14.1 months, the median overall survival was 12.0 months in trilaciclib arm and 8.8 months in placebo arm (HR, 0.69; 95 % CI: 0.40-1.22). Median progression-free survival was 4.8 months and 4.3 months, respectively (HR, 0.86; 95 % CI: 0.53-1.39). Trilaciclib had a well-tolerated safety profile. CONCLUSIONS Trilaciclib in the Chinese population demonstrated a similar PK and safety profile as seen in other global trials. There was significant reduction of DSN in Cycle 1, thereby substantiating the myeloprotective effects of trilaciclib in Chinese ES-SCLC patients.

Abstract
Chemotherapy can often cause a variety of side effects including bone marrow (BM) suppression, termed as myelosuppression. Accordingly, facile and effective management of chemotherapy-induced myelosuppression is currently a pivotal task for experimental pathologists and oncologists. Here, we chose to use activated carbon (AC) with an extensive surface area for studying its possible protective effectiveness with respect to BM in doxorubicin (DOX)-treated rats. Spherical AC with an extended surface area up to 4490 m2/g was prepared for per os (p/o) delivery, whereas for intraperitoneal (i/p) delivery we used the powdered form of AC that was derived from the aforementioned spherical AC. During the monthly treatment of animals with AC and DOX these two components were delivered alternately (not in the same day). After treatment, BM cells were isolated from femurs of sacrificed animals, stained with acridine orange (AO) and analyzed by flow cytometry. Regardless of the route of AC delivery (p/o or i/p), apparent myeloprotection with a possible regenerative effect was observed in animals that received DOX, as evidenced by recovery of the populations of total nucleated cells (TNC) and polychromatic (immature) erythrocytes accompanied by a considerable reduction of the number of apoptotic/dead cells among TNC (≤2.0%). Moreover, as a result of AC administrations, there was a significant increase of AO green and far-red fluorescence intensities in the population of TNC, which is suggestive of the ongoing quantitative and conformational changes in DNA and RNA associated with cell recovery and proliferation. Thus, AC preparations under the present experimental conditions can effectively tackle DOX-induced myelosuppression via mechanisms not necessarily associated with adsorptive detoxification.

Abstract
Chemotherapy is the backbone of the treatment of several solid tumours and lymphomas. Myelotoxicity is often a dose-limiting toxicity and myeloprotection has always been investigated. In fact, over the years, several approaches have been studied in order to reduce the incidence of haematological toxicities and allow patients to receive effective, full-dose, chemotherapy. After the use of stimulating factors, such as granulocyte colony-stimulating factors and erythropoiesis-stimulating agents, in the very last years, a new approach has emerged. Trilaciclib, a cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor, has been studied and it has been demonstrated in several clinical trials to reduce the incidence of myelotoxicity in small-cell lung cancer patients treated with chemotherapy or chemo-immunotherapy. Its potential role has not been fully studied yet, but it represents a highly effective tool to reduce myelotoxicity, widen the applicability of full-dose chemotherapy, even in frailer patients, and finally to increase the efficacy of chemotherapy in those tumours where relative dose intensity is a standard to achieve to get the best clinical results.

Abstract
BACKGROUND Chemotherapy-induced myelosuppression (CIM) and its sequalae cause significant side effects and harm to quality of life. Trilaciclib is an intravenous CDK4/6 inhibitor that is administered prior to chemotherapy to protect hematopoietic stem and progenitor cells from chemotherapy-induced damage (myeloprotection). PATIENTS AND METHODS Data from three randomized, double-blind, placebo-controlled studies (NCT02499770, NCT03041311, and NCT02514447) were pooled to evaluate the effects of trilaciclib administered prior to standard-of-care chemotherapy (first-line etoposide plus carboplatin [E/P], first-line E/P plus atezolizumab, and second-/third-line topotecan) in patients with extensive-stage small cell lung cancer (ES-SCLC). The primary endpoints were duration of severe neutropenia (absolute neutrophil count < 0.5 × 109 cells/L) in cycle 1 and occurrence of severe neutropenia. Additional prespecified endpoints further assessed the effect of trilaciclib on myeloprotection, health-related quality of life (HRQoL), antitumor efficacy, and safety. RESULTS Of 242 randomized patients, 123 received trilaciclib and 119 received placebo. Compared with placebo, administration of trilaciclib prior to chemotherapy resulted in significant decreases in most measures of multilineage CIM. The reduction in hematologic toxicity translated into the reduced need for supportive care interventions and hospitalizations due to CIM or sepsis and improvements in HRQoL domains related to the protected cell lineages, including fatigue, physical wellbeing, and functional wellbeing. Antitumor efficacy was similar for patients receiving trilaciclib or placebo. CONCLUSION Administering trilaciclib prior to chemotherapy resulted in clinically meaningful reductions in CIM and its consequences and improved patient HRQoL, with no impact on the antitumor efficacy of three individual chemotherapy regimens used in the first- or second-/third-line treatment of ES-SCLC.

Abstract
PURPOSE RRx-001, a minimally toxic tumor-associated macrophage and neutrophil-repolarizing agent, is under investigation in Phase II clinical trials as a sensitizer/resensitizer to cisplatin and carboplatin. On the basis of anecdotal clinical observations of improved platinum tolerability following a priming period with RRx-001 as well as preclinical studies that have previously demonstrated radioprotection of intestinal stem cells and cardioprotection from doxorubicin, the in vivo cytoprotective potential of RRx-001 pretreatment against cisplatin-induced bone marrow suppression and renal toxicity was investigated. METHODS BALB/c mice were divided into three groups: (1) no treatment, (2) vehicle and cisplatin only, and (3) RRx-001 and cisplatin. RRx-001 treatment (5 mg/kg every other day for 3 days) was initiated 3 days prior to cisplatin administration. Blood was collected from the femoral vein at different intervals to measure total hemoglobin and leukocyte counts as well as renal functional markers (serum urea, creatinine and creatinine clearance). Metaphase spreads were prepared from whole bone marrow cells as markers of clastogenicity. RESULTS RRx-001 pretreatment significantly decreased (P < 0.05) the blood urea nitrogen and creatinine levels. A statistically significant (P < 0.05) reduction in the mean total chromosome aberration frequency per metaphase in the RRx-001 and cisplatin group compared to the cisplatin-only group was observed. CONCLUSIONS This study is the first to demonstrate that RRx-001 has nephro-, geno- and myeloprotective effects in vivo. Importantly, RRx-001 did not protect sarcoma-180 solid tumor xenografts against cisplatin-induced cytotoxicity. These results potentially support the use of RRx-001 as a chemoprotector against cisplatin-induced toxicities.
