Abstract
BACKGROUND Dysregulation of EZH2 has a crucial role in lymphomagenesis. We did a first-in-human study to assess the safety, pharmacokinetics, pharmacodynamics, and preliminary clinical activity of SHR2554, an oral EZH2 inhibitor, in patients with relapsed or refractory mature lymphoid neoplasms, including B-cell lymphomas, T-cell lymphomas, and classical Hodgkin lymphoma. METHODS This was a multicentre, dose-escalation, dose-expansion, and clinical expansion phase 1 study done at 13 hospitals in China. Eligible patients had histologically or cytologically confirmed mature lymphoid neoplasms that had relapsed or were refractory to standard systemic therapies or had no standard-of-care. The study included a dose-escalation phase, at doses of SHR2554 from 50 mg to 800 mg twice daily; a dose-expansion phase, at two selected doses; and a subsequent clinical expansion phase at the recommended phase 2 dose in selected tumours. Primary endpoints were the safety, maximum tolerated dose, and recommended phase 2 dose. Objective response rate was a secondary endpoint. Safety and activity were assessed in all patients who received at least one dose of SHR2554 and had at least one post-baseline evaluation. This study is registered with ClinicalTrials.gov, NCT03603951, and follow-up is ongoing. FINDINGS Between Aug 14, 2018, and July 13, 2021, 113 patients received SHR2554. At data cutoff (Sept 10, 2021), the median follow-up duration was 7·0 months (IQR 3·7-12·0). 71 (63%) patients were men and 42 (37%) were women, 110 (97%) were of Han ethnicity and 3 (3%) of other ethnicities, and 53 (47%) had received three or more lines of previous anticancer therapies. Dose-limiting toxicities occurred in two (67%) of three patients who received 400 mg SHR2554 twice daily and one (17%) of six patients who received 350 mg SHR2554 twice daily. The maximum tolerated dose and recommended phase 2 dose was determined to be 350 mg twice daily. The most common grade 3 or 4 treatment-related adverse events in all 113 patients were decreased platelet count (20 [18%]), decreased neutrophil count (ten [9%]), decreased white blood cell count (nine [8%]), and anaemia (seven [6%]). 18 (16%) patients had serious treatment-related adverse events. Two patients (2%) died due to treatment-related adverse events: one (1%) due to skin infection and toxic epidermal necrolysis and one (1%) due to respiratory failure. 107 (95%) of the 113 enrolled patients had post-baseline assessments for tumour response and were included in the activity analysis. 46 (43%; 95% CI 33-53) of these 107 patients had an overall response. INTERPRETATION SHR2554 showed an acceptable safety profile and promising antitumour activity in patients with relapsed or refractory lymphomas, providing evidence for future investigations.

Abstract
Antibody-drug conjugates (ADCs) are a promising class of immunotherapies with the potential to specifically target tumor cells and ameliorate the therapeutic index of cytotoxic drugs. ADCs comprise monoclonal antibodies, cytotoxic payloads with inherent antitumor activity, and specialized linkers connecting the two. In recent years, three ADCs, brentuximab vedotin, polatuzumab vedotin, and loncastuximab tesirine, have been approved and are already establishing their place in lymphoma treatment. As the efficacy and safety of ADCs have moved in synchrony with advances in their design, a plethora of novel ADCs have garnered growing interest as treatments. In this review, we provide an overview of the essential elements of ADC strategies in lymphoma and elucidate the up-to-date progress, current challenges, and novel targets of ADCs in this rapidly evolving field.

J Med Econ 2020; 23:1130-1141. [PMID: 32620061 DOI: 10.1080/13696998.2020.1791890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 10/23/2022]
Abstract
AIMS Obinutuzumab (GA101; G) is a new treatment for follicular lymphoma (FL) that is anticipated to have greater efficacy than the current treatment, rituximab (R). The aim of this study was to evaluate the cost-effectiveness of G plus chemotherapy (G + Chemo) against that of R plus chemotherapy (R + Chemo) for patients in Japan with previously untreated FL. MATERIALS AND METHODS We localized a previously reported cost-effectiveness model using the Japanese cost data. For estimating costs adapted in the model, FL patients treated with R were identified from Japanese hospital-based claims database and classified into three treatment regimen groups according to chemotherapies used with R: CHOP, CVP, and bendamustine (B). Based on services per patient and cost items, parameters determining the cost amounts were derived using a multivariate generalized linear mixed model to estimate the direct medical costs for each treatment regimen group for G and R. For the utility, same values in the previous model were used. Lifetime cost and quality-adjusted life year (QALY) were estimated under the payer's perspective. RESULTS The calculated incremental cost-effectiveness ratios (ICERs) in million JPY per QALY for G-CHOP vs. R-CHOP, G-CVP vs. R-CVP, and G-B vs. R-B were 5.4, 4.3, and 4.8, respectively. ICERs were lower than 7.5 million JPY per QALY, which is the cost-effectiveness threshold for cancer treatments, and showed that G + Chemo is a cost-effective treatment regimen for Japanese patients with previously untreated FL. Lifetime direct medical costs were lowest in the R-B group because hospitalization costs that accounted for most of the total cost were lowest in this group. Limitations and conclusions: The cost-effectiveness of G + Chemo is acceptable in Japan. Differences in the direct medical costs among treatment regimen groups were mostly due to hospitalization costs. This is probably because many Japanese hematologists choose inpatient treatments over outpatient treatments in CHOP-based induction therapy.
