"Immunotherapies have shown promise in how we treat cancer, and the investigation of combination therapies may uncover additional possibilities. We look forward to working with Merck KGaA, Darmstadt, Germany to explore how we can bring the potential of immunotherapy to more patients, especially considering a
Phase 1 study of monotherapy with VX15/2503 in patients with solid tumors has already suggested its potential for use in combination therapies," said Dr. Maurice Zauderer, CEO of Vaccinex.

In preclinical studies, anti-semaphorin 4D antibodies have been shown to increase infiltration of tumoricidal immune cells while simultaneously reducing multiple types of immunosuppressive cells in tumors. Anti-semaphorin 4D antibody was found to synergize with a checkpoint inhibitor antibody to promote tumor eradication.

"Non-small cell lung cancer continues to be one of the most challenging of cancers worldwide, and we believe in investigating promising avenues to address this need," said Alise Reicin, M.D., Head of Global Clinical Development in the biopharma business of Merck KGaA, Darmstadt, Germany. "Through this partnership with Vaccinex, we are exploring an innovative combination with avelumab that we hope will provide a new option for patients with this deadly cancer."

Further details of the collaboration were not disclosed.

*Avelumab is jointly developed by Merck KGaA, Darmstadt, Germany and Pfizer.

About Non-Small Cell Lung Cancer

Globally, lung cancer is the most common cause of cancer-related deaths in men and the second most common in women1, responsible for more deaths than colon, breast and prostate cancer combined.2 NSCLC is the most common type of lung cancer, accounting for 80 to 85 percent of all lung cancers.3 The five-year survival rate for people diagnosed with late-stage lung cancer that has spread (metastasized) to other areas of the body is 4 percent.4

About Avelumab

Avelumab (also known as MSB0010718C) is an investigational, fully human antibody specific for a protein found on tumor cells called PD-L1, or programmed death ligand-1. Avelumab is thought to have a dual mechanism of action which may enable the immune system to find and attack cancer cells. By binding to PD-L1, avelumab is thought to prevent tumor cells from using PD-L1 for protection against white blood cells such as T-cells, exposing them to anti-tumor responses. Avelumab may also help white blood cells such as natural killer (NK) cells find and attack tumors in a process known as ADCC, or antibody-dependent cell-mediated cytotoxicity. In November 2014, Merck KGaA, Darmstadt, Germany, the science and technology company, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.

Title: A phase 1b/2 study of the nanoparticle-drug conjugate CRLX101 in combination with weekly paclitaxel in patients with platinum-resistant ovarian cancer
Date and time: Saturday, October 8 – 13:00 to 14:00 pm Central European Time
Abstract number: 1483
Location: Hall E
Poster board number: 864P
Summary: CRLX101 is an investigational NDC containing the payload camptothecin. This Phase 1b/2 trial evaluates the potential synergy of CRLX101, a topoisomerase 1 inhibitor, in combination with paclitaxel, a standard of care taxane, in patients with platinum-resistant ovarian cancer (PROC). In this trial, CRLX101 is dosed every other week at 12 or 15 mg/m2 in conjunction with weekly paclitaxel at 80 mg/m2. Data from the nine patients in the Phase 1b portion of the trial suggest CRLX101 administered every other week in combination with weekly paclitaxel demonstrate antitumor activity. Additionally, the combination has been generally well tolerated with no dose-limiting toxicities reported. Early data from the first nine patients in the Phase 2 portion of the trial also show activity and tolerability.

Title: Evaluation of weekly dosing of CRLX101 alone and in combination with bevacizumab in patients with advanced solid tumors
Date and time: Monday, October 10 – 13:00 to 14:00 pm Central European Time
Abstract number: 1781
Location: Hall E
Poster board number: 393P
Summary: CRLX101, an investigational NDC containing the payload camptothecin, has been shown to be active in different tumor types as a topoisomerase 1 inhibitor. This study evaluated the dosing and tolerability of a weekly dosing schedule of CRLX101 alone and in combination with bevacizumab. In arm 1, CRLX101 was administered intravenously as a monotherapy at 12 or 15 mg/m2 weekly; in arm 2, this same dosing regimen was administered in combination with every other week dosing of bevacizumab at 10 mg/kg. In arm 1, the maximum tolerated dose for CRLX101 weekly monotherapy is 15 mg/m2. In arm 2, the maximum tolerated dose for CRLX101 in combination with bevacizumab is either 12 mg/m2 weekly or 15 mg/m2 for 3 of 4 weeks. Partial responses were observed in three patients. There was increased cystitis, but no new safety concerns were observed.

Title: Pharmacokinetics of CRLX101 administered weekly in patients with advanced solid tumors
Date and time: Monday, October 10 – 13:00 to 14:00 pm Central European Time
Abstract number: 1767
Location: Hall E
Poster board number: 394P
Summary: CRLX101 is an investigational NDC containing the payload camptothecin. This study evaluated the pharmacokinetics of CRLX101 in patients with advanced solid tumors. CRLX101 was administered intravenously at 12 or 15 mg/m2 on a weekly dosing schedule. The data suggest CRLX101 exhibits high drug retention in the plasma, slow clearance and controlled slow release of camptothecin from the NDC without drug accumulation, supporting weekly dosing of CRLX101 at 15 mg/m2, which represents a 100% increase in dose intensity when compared to a dosing schedule of every other week.

Title: A dose-escalation study of weekly intravenous CRLX301 in patients with advanced solid tumor malignancies
Poster presentation: Monday, October 10 – 13:00 to 14:00 pm Central European Time
Abstract number: 1793
Location: Hall E
Poster board number: 413Tip
Summary: CRLX301 is an investigational NDC containing the payload docetaxel currently being investigated in a Phase 1/2a trial of patients with advanced solid tumors. The first portion of the trial determined the maximum tolerated dose for IV CRLX301 administered every three weeks to be 75 mg/m2. The second portion of the trial is evaluating the maximum tolerated dose for weekly administration of CRLX301. Based on data from the first portion of this trial, the weekly starting dose was 25 mg/m2. This dose escalating trial also evaluates safety, PK and antitumor activity.

About CRLX101

CRLX101 is a nanoparticle-drug conjugate (NDC) designed to concentrate in tumors and slowly release its anti-cancer payload, camptothecin, inside tumor cells. CRLX101 inhibits topoisomerase 1 (topo 1), which is involved in cellular replication. CRLX101 has shown activity in multiple tumor types, both as monotherapy and in combination with other cancer treatments. CRLX101 is in Phase 2 clinical development and has been dosed in more than 400 patients. The U.S. FDA has granted CRLX101 Orphan Drug designation for the treatment of ovarian cancer, Fast Track designation in combination with paclitaxel for platinum-resistant ovarian carcinoma, fallopian tube or primary peritoneal cancer, and Fast Track designation in combination with Avastin in metastatic renal cell carcinoma.

About CRLX301

CRLX301 is a dynamically tumor-targeted NDC designed to concentrate in tumors and slowly release its anti-cancer payload, docetaxel, inside tumor cells. In preclinical studies, CRLX301 delivers up to 10 times more docetaxel into tumors, compared to an equivalent milligram dose of commercially available docetaxel and was similar to or better than docetaxel in seven of seven animal models, with a statistically significant survival benefit seen in five of those seven models. In addition, preclinical data show that CRLX301 had lower toxicity than has been reported with docetaxel in similar preclinical studies. CRLX301 is in Phase 1/2a clinical development.

On October 6, 2016 CANCER RESEARCH TECHNOLOGY (CRT) – the development and commercialisation arm of Cancer Research UK – reported that it has received a success payment from GlaxoSmithKline resulting from its collaboration developing molecules targeting cancer epigenetics (Press release, Cancer Research Technology, JUN 6, 2016, View Source [SID1234523177]).

Under the agreement, scientists at the Drug Discovery Unit at the Cancer Research UK Manchester Institute at the University of Manchester received promising early molecules for the project from GlaxoSmithKline and created potential new drug development candidates that target a key protein involved in epigenetic regulation.

CRT will receive development milestones and royalties on sales of products from the collaboration, and has the right to develop the molecules further if GlaxoSmithKline declines to do so.

The Drug Discovery Unit at Cancer Research UK’s Manchester Institute will support GSK scientists developing these drugs and will continue to develop other compounds as part of the collaboration.

Epigenetics – the way cells control how and when genes are turned on or off – can be disrupted in many cancers meaning these drugs could be used to treat many cancers.

Dr Donald Ogilvie, head of the Drug Discovery Unit at Cancer Research UK’s Manchester Institute, said: "We’re extremely pleased with the success of this project, which has allowed us to research a challenging area and ensure that it’s an effective way of targeting cancer.

"The Drug Discovery Unit aims to develop new treatments ready for the clinic as efficiently as possible. By working alongside GlaxoSmithKline scientists we’ve been able to reduce the risk in the development of these drugs and make them more likely to progress through to clinic to achieve our goal of getting new treatments to cancer patients sooner."

Dr Phil L’Huillier, Cancer Research Technology’s director of business development, said: "We’re delighted that our Manchester Drug Development Unit’s work has been so successful, triggering an early success payment from GlaxoSmithKline. This showcases our world class drug development capabilities.

"Drugs targeting epigenetics are a growing area of research and we’re pleased to be making an impact in this area. Being at the forefront of this research alongside one of the world’s biggest pharmaceutical companies means we have a real opportunity to develop new drugs for cancer patients."
