The prevalence of safety-related postmarketing label modifications of medications for hematological malignancies is unknown. We identified 35 new drugs indicated for hematological malignancies approved by the US Food and Drug Administration between January 1999 and December 2014. Characteristics of supporting trials and safety-related label modifications from approval to December 2017 were collected from drug labels. Regulatory review and approval pathways were also collected. New drug approvals were supported by trials with a median of 167 patients (interquartile range 115–316). All drugs were approved based on surrogate endpoints. Twenty-seven drug approvals (77%) were not supported by randomized controlled trials. All drugs received orphan drug designation, and most were granted fast track designation, priority review, and accelerated approval (83, 74, and 60%, respectively). A total of 28 drugs (80%) had postmarketing safety-related label modifications. Additions to black box warnings, contraindications, warnings and precautions, and common adverse reactions were identified in 31, 11, 77, and 46% of drugs, respectively. Five drugs (14%) were permanently or temporarily withdrawn from the US market. Drugs for hematological malignancies are often approved based on limited evidence through expedited regulatory pathways with incomplete safety profiles. Hematologists should be vigilant for unrecognized side effects when prescribing newly approved drugs.

Powerful Incentive

In December 2014, the United States government expanded the Priority Review Voucher (“PRV” or “voucher”) program to include Ebola and other related Filoviruses. By doing so, lawmakers provided a potentially powerful incentive for drug companies to invest time and money in the development of novel medicines for terrifying diseases. This expansion is one of several additions made to the PRV programs since 2012. Many companies rely on voucher resale to recoup research and development (“R&D”) costs; however, it is unclear whether the PRV program could be overextended, thereby diluting the value of the incentives. In this paper, I use historical approval data from the Food and Drug Administration (“FDA”) and United States drug revenue data to better understand the secondary market value of a PRV. The data suggests that that purchase prices of a PRV could continue to climb; despite this, the market size for these vouchers is limited. The implications of these findings are discussed further.

Immunotherapies are becoming increasingly important in the treatment armamentarium of a variety of malignancies. Immune checkpoint inhibitors are the most representative drugs receiving regulatory approval over the past few years. In a recent study published in Clinical Cancer Research, we demonstrated that these agents are being developed faster than other prior anticancer therapies. All checkpoint inhibitors received priority review, being granted with at least one Food and Drug Administration expedited program. Hence, some of them are getting marketing approval after preliminary trials. The model continues to rely on phase I trials, designed with traditional models for dose definition, although a substantial number of patients are treated during the dose expansion cohorts. We demonstrated that efficacy and safety are reasonably predicted from the dose-finding portion of phase I trials with these agents, assuring a low treatment-related mortality for patients throughout the development process. In this article, we further discuss and summarize these findings and update some recent approval information for immune checkpoint inhibitors.

Abstract Sacituzumab govitecan (SG) is an antibody drug conjugate (ADC) that targets Trop-2 for the selective delivery of SN-38 to tumors. SG carries SN-38, a topoisomerase inhibitor active in the nanomolar range for most cells (including TNBC and GBM) and freely cross the blood brain barrier. SN-38 is conjugated to SG by a linker designated CL2A which is sensitive to acidic conditions. SG has since been granted priority review designation by the FDA, with approval anticipated for triple negative breast cancer. Brain metastases is a significant concern in this patient population, but whether this agent is able to target the CNS through the blood brain barrier is unknown. Based upon the characteristics of this specific ADC, including the use of a pH labile linker and a payload with good CNS penetration, it is our specific hypothesis that the SG can achieve intratumoral concentrations of SN-38 sufficient to achieve therapeutic benefit in patients with neoplastic involvement of the brain. We further hypothesize that while total concentration of SN-38 will correlate with expression of trop2, free SN-38 will correlate more strongly with intratumoral hypoxia. To address this, we are performing a non-randomized, prospective study of SG in subjects with CNS involvement and planned surgical resection. SG is given as single dose at 10mg/kg pre-operatively on Day-1. Surgery will be followed by post-operative treatment with sacituzumab govitecan given intravenously with standard dose of 10 mg/kg on day1 and day 8 of 21-day cycle, until disease progression. Approximately 20 patients, 2 cohorts of 10 patients each with GBM and breast brain tumors, will be enrolled. Tumors will be analyzed for total antibody, free SN-38, and total SN-38 (free SN-38 + Antibody-SN38) concentrations in tumor tissue. Correlations will be made to Trop2 expression and hypoxia. Interim results will be presented.
