The data highlight bemcentinib’s potential to reverse tumour immune suppression and enhance immune checkpoint inhibitor efficacy.

The authors show that bemcentinib targets immune suppression mechanisms in the tumour microenvironment that improve immunotherapy in murine tumour models of non-small cell lung (NSCLC), triple negative breast (TNBC) and pancreatic cancer. Bemcentinib treatment reduces myeloid-derived suppressor cells and the altered immune landscape is associated with increased tumour infiltration of T cells (NK and CD8+) and enhanced therapy responses.

A validated AXL immunohistochemistry (IHC) method for use on patient samples to identify the presence of AXL on tumour cells and immune cells in the tumour microenvironment was presented. The authors report that across 92 banked tumour biopsies from patients with TNBC or NSCLC 70% were found to stain positive for AXL using this IHC method. The IHC method is now in use to analyse biopsies taken in connection with the company’s phase II combination trials of bemcentinib with KEYTRUDA in patients with advanced NSCLC or TNBC.

Professor James Lorens, BerGenBio Chief Scientific Officer, commented: "These results highlight a clear and important role for AXL in aggressive disease and resistance to immune therapy in particular. They provide continued confidence in the potential of combining bemcentinib with immune checkpoint inhibitors to improve cancer treatment, and support for our Phase II clinical trial programme of bemcentinib combined with the blockbuster immune checkpoint inhibitor KEYTRUDA, interim results from which are expected during 2018."

During a presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) in Chicago this weekend Lilly revealed that Verzenio (abemaciclib), a cyclin-dependent kinase inhibitor, provided even longer progression-free survival than originally believed. Last fall Eli Lilly released interim-data from the MONARCH 3 trial that showed PFS was estimated at 14 months. Now though data shows Verzenio in combination with an aromatase inhibitor (AI) provides progression-free survival of 28 months.

"That’s a significant prolongation in progression-free survival that is important for the lives of patients," Levi Garraway, senior vice president of global development and medical affairs at Eli Lilly told BioSpace in an exclusive interview. "We’ve been happy with the news that this gives women with breast cancer one more option."

In February the FDA gave approval for the treatment of postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer. That approval marked the third time the FDA gave the drug the green light since its first regulatory win in September 2017.

By adding abemaciclib to endocrine therapy as part of a treatment regimen, Eli Lilly said the program demonstrated improved progression-free survival in patients with HR+/HER2-negative breast cancer. In patients with measurable disease, the objective response rate was 55.4 percent in the abemaciclib arm and 40.2 percent in the placebo arm, according to data.

Within the MONARCH 2 and MONARCH 3 clinical trial subgroup populations, researchers at Eli Lilly identified certain clinical characteristics of the disease that typically confer a less favorable prognosis. Eli Lilly believes this information may help clinicians optimize treatment decisions, including the use of CDK4 & 6 inhibitors, and potentially provide the groundwork for more individualized therapy.

During the conference Garraway said he engaged with several doctors about the use of cyclin-dependent kinases inhibitors in the treatment of breast cancer. He said the response they have seen from prescribers is positive, which indicates there is a path for cyclin-dependent kinases inhibitors.

"These doctors, they’ve been seeing some positive moves and are gaining confidence in its (Verzenio) use," Garraway said.

With the success that Eli Lilly has had with Verzenio, the company now aims to determine if it can be used as a treatment in other types of breast cancer, as well as other cancer indications. Currently, the company has Verzenio in a study in the high-risk adjuvant breast cancer setting, as well as an ongoing Phase II study in Her2+ breast cancer. Garraway said data from the mid-stage trial is expected by the end of the year. While Garraway did not provide many details on the Phase II study, He said it was designed so that if the data readout is strong enough there is a chance Eli Lilly could seek regulatory approval on that data alone. But, he quickly noted that it depends on whether or not there is a large enough of an effect from the treatment for the company to go into regulatory discussions as opposed to a Phase III study.

"There’s a biological rationale for the testing and we’re looking forward to seeing the results later this year," Garraway said.

For potential uses outside of breast cancer Garraway would not disclose what areas the company is exploring with Verzenio, he said the company has identified some areas "that are worth the investment."

Not related to Eli Lilly’s presentations at AACR (Free AACR Whitepaper), this morning the company announced a partnership with Boehringer Ingelheim and the University of Oxford to investigate the effects of Jardiance on the progression of kidney disease and the occurrence of cardiovascular death, in adults with established chronic kidney disease with and without diabetes. The primary outcome of the study is to assess the effect of Jardiance on time to clinically relevant kidney disease progression or cardiovascular death.

On April 18, 2018 Tarveda Therapeutics, Inc., a clinical stage biopharmaceutical company discovering and developing Pentarins as a new class of potent and selective cancer medicines, reported that presented data on the efficacy of PEN-866, a novel miniature drug conjugate comprised of a Heat Shock Protein 90 (HSP90) targeting ligand attached through a cleavable linker to SN-38 when combined with Poly ADP ribose polymerase (PARP) inhibitors in preclinical models of human cancer (Press release, Tarveda Therapeutics, 18 18, 2018, View Source [SID1234525520]). SN-38 is a potent topoisomerase 1 inhibitor, and is the active metabolite of irinotecan. The poster titled, "Combination of the miniature drug conjugate PEN-866 with PARP inhibitors as a rational approach to overcoming limitations of PARP inhibitor monotherapy" was presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting taking place April 14-18, 2018 in Chicago.

The data presented evaluates the use of PEN-866 in combination with PARP inhibitors as an approach to overcoming limitations of PARP inhibitor monotherapy, such as dose limiting toxicities, in preclinical models of human cancer. In efficacy studies carried out in both BRCA mutant and BRCA wildtype tumor xenografts, combinations of PEN-866 and PARP inhibitors resulted in greater efficacy than that of the monotherapy in both tumor types.

"Results presented today show that when combined with PARP inhibitors, PEN-866 could avert the dose limiting toxicities often seen when PARP inhibitors are combined with other anti-cancer therapies," said Richard Wooster, Ph.D., President of Research and Development and Chief Scientific Officer of Tarveda Therapeutics. "The high levels of accumulation and retention of the combination of PEN-866 and a PARP inhibitor in xenograft tumors demonstrate the potential for greater efficacy compared to single agent therapy."

PEN-866’s linker cleavage provides sustained release of SN-38 at a high local tumor concentration leading to DNA damage and apoptosis of tumor cells, which results in broad antitumor activity in a range of preclinical xenograft models. When PEN-866 is administered in combination with PARP inhibitors, the inhibitors reduce DNA repair activity in tumor cells, enabling PEN-866 to maximize its efficacy in damaging cancer cell DNA. A pharmacodynamic assessment of DNA damage performed in tumors responsive to the combination treatment further demonstrated the efficacy of the therapy.

"The mechanistic synergy of PEN-866, carrying the payload SN-38 which is a potent topoisomerase I inhibitor, and PARP inhibitors suggests that this combination therapy could be an attractive approach in the clinical evaluation of PEN-866," said Drew Fromkin, President and Chief Executive Officer of Tarveda Therapeutics. "We look forward to continued studies of PEN-866, including our first-in-human Phase 1 clinical trial of PEN-866 to evaluate safety and efficacy."

About PEN-866
PEN-866 exploits the activation of Heat Shock Protein 90 (HSP90) in tumors to accumulate and release its potent anti-cancer payload, SN-38. PEN-866 is a miniature conjugate that comprises a small molecule, HSP90-targeting ligand linked to SN-38, the active metabolite of irinotecan. The conjugate accumulates and is retained in tumors and, by way of a sustained release of SN-38, causes prolonged DNA damage and tumor regressions in multiple patient-derived and other xenograft tumor models. PEN-866 is currently being studied in first-in-human clinical trials to evaluate safety and efficacy in patients with advanced solid tumors.

About Pentarins
Tarveda is developing Pentarins, potent and selective miniature drug conjugates with high affinity for specific cell surface and intracellular targets. Pentarins are engineered to bind to their tumor cell targets and provide sustained release of their potent therapeutic payloads deep into solid tumor tissue. Comprised of a targeting ligand conjugated to a potent cancer cell killing agent through a tuned chemical linker, Pentarins are designed to overcome the deficits of both larger antibody drug conjugates and small molecules that limit their therapeutic effectiveness against solid tumors. Together, the components of Tarveda’s Pentarins have distinct, yet synergistic, anticancer attributes: the small size of Pentarins allows for rapid and deep penetration into the tumor tissue, the ligand’s targeting ability allows for specific binding and retention in tumor cells, and the chemical linker is tuned to optimize the release of the potent, cell killing payload inside the cancer cells for efficacy.
