This is a dose escalation study in female subjects with relapsed ovarian cancer (including epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube cancer). Approximately 30 to 40 subjects will be administered a combination of conatumumab and birinapant.
In the initial dose-escalation stage of the study, adult female subjects will receive conatumumab in combination with increasing doses of birinapant in dose-escalation cohorts to determine the MTD of birinapant when administered with a fixed dose of conatumumab.
In safety expansion stage, adult female subjects will receive conatumumab in combination with birinapant at the MTD of the combination.

The generation of stable microvessels in ischemia is mediated by endothelial cell derived TRAIL

Reversal of ischemia is mediated by neo-angiogenesis requiring endothelial cell (EC) and pericyte interactions to form stable microvascular networks. We describe an unrecognized role for tumor necrosis factor–related apoptosis-inducing ligand (TRAIL) in potentiating neo-angiogenesis and vessel stabilization. We show that the endothelium is a major source of TRAIL in the healthy circulation compromised in peripheral artery disease (PAD). EC deletion of TRAIL in vivo or in vitro inhibited neo-angiogenesis, pericyte recruitment, and vessel stabilization, resulting in reduced lower-limb blood perfusion with ischemia. Activation of the TRAIL receptor (TRAIL-R) restored blood perfusion and stable blood vessel networks in mice. Proof-of-concept studies showed that Conatumumab, an agonistic TRAIL-R2 antibody, promoted vascular sprouts from explanted patient arteries. Single-cell RNA sequencing revealed heparin-binding EGF-like growth factor in mediating EC-pericyte communications dependent on TRAIL. These studies highlight unique TRAIL-dependent mechanisms mediating neo-angiogenesis and vessel stabilization and the potential of repurposing TRAIL-R2 agonists to stimulate stable and functional microvessel networks to treat ischemia in PAD.

PURPOSE:

Colorectal cancer (CRC) is the third most frequently diagnosed cancer and this study aimed to develop a conatumumab decorated, irinotecan prodrug and quercetin co-loaded delivery system for combined and targeted colorectal cancer treatment.

METHODS:

A conatumumab (C) decorated, irinotecan prodrug (I-p) and quercetin (Q) co-encapsulated NLC (C I-p/Q NLC) was developed. In vitro and in vivo antitumor efficiency of NLC was evaluated on CRC cells and mice xenograft.

RESULTS:

The results showed that the HT-29 cells uptake of C I-p/Q NLC was over 70%. Reactive oxygen species (ROS) sensitive irinotecan prodrug formulation showed improved drug release ability in hypoxic conditions. C I-p/Q NLC showed significantly higher cytotoxicity than non-decorated NLC, single drug-loaded NLC and free drugs. In vivo studies in a CRC-bearing model corroborated the capability of nanoparticles for the inhibition of cancer, leading to a reduction of tumor growth without systemic toxicity.

CONCLUSION:

The conatumumab decorated, ROS sensitive prodrug contained combination nano-system is a promising platform for CRC therapy.

Efficacy and Safety of Regorafenib in Combination with Chemotherapy as Second-Line Treatment in Patients with Metastatic Colorectal Cancer: A Network Meta-Analysis and Systematic Literature Review

INTRODUCTION:

Although various therapies are available for the treatment of metastatic colorectal cancer (mCRC), there is lack of head-to-head evidence. Recent studies have demonstrated the efficacy of chemotherapy in combination with different biological agents including regorafenib in second-line therapy in patients with mCRC. We conducted a network meta-analysis (NMA) to estimate the relative efficacy and safety of regorafenib in combination with chemotherapy compared to other biological agents with chemotherapy combinations.

METHODS:

A literature search was conducted in PubMed, Embase, and Cochrane databases to identify all randomized controlled trials (RCTs) evaluating the efficacy and safety of bevacizumab, regorafenib, panitumumab, cetuximab, ramucirumab, conatumumab, ganitumab, and aflibercept in combination with chemotherapy against chemotherapy alone as second-line setting from inception to 7 February 2019 in patients with mCRC. The survival outcomes were analyzed by the frequentist statistical approach (R software, netmeta package) while the level of individual treatment arms was assessed using the Bayesian method (R software, gemtc package).

RESULTS:

We identified 12 articles involving eight RCTs studies analyzing 6805 patients. The studies compared bevacizumab (3), regorafenib (1), panitumumab (2), cetuximab (3), ramucirumab (1), conatumumab (1), ganitumab (1), and aflibercept (1) against chemotherapy alone as comparator. The progression-free survival (PFS) revealed that regorafenib performed better than aflibercept (HR 0.9631, 95% CI 0.6785-1.367), ganitumab (HR 0.7228, 95% CI 0.3985-1.3109), panitumumab (HR 0.9653, 95% CI 0.6781-1.3742), and ramucirumab (HR 0.9206, 95% CI 0.6504-1.303). Regorafenib performed better than bevacizumab (OR 0.797, 95% CI 0.328-1.88) in terms of tumor response. Safety analysis showed that regorafenib performed better in reducing grade ≥ 3 adverse events (AE) than cetuximab and conatumumab, neutropenia than conatumumab, and fatigue than cetuximab.

CONCLUSIONS:

Regorafenib combined with chemotherapy might be a potential alternative to conventional therapeutic options in second-line treatment of patients with metastatic colorectal cancer and could be considered as the best option for treating patients with KRAS and BRAF mutated mCRC. However future RCTs are needed to confirm these results.
