The preclinical data demonstrate that ATOR-1015 physically localizes to the tumor and selectively activates the immune system in the tumor area, confirming the intended ATOR-1015 mechanism of action.

ATOR-1015 is primarily designed for combination therapy with a PD-1 blocking antibody, and the potential of this approach is supported with preclinical data reporting enhanced anti-tumor effect of ATOR-1015 in combination with an anti-PD-1 antibody, as compared to anti-PD-1 monotherapy. In addition, ATOR-1015 demonstrated superior efficacy compared to mono-targeting CTLA-4 and OX40 antibodies.

"The results presented in Chicago confirm that our CTLA-4 bispecific antibody ATOR-1015 selectively activates the immune system in the tumor area. This offers great potential for an improved benefit/risk profile for cancer patients. We are more and more excited about the significant prospects for this unique compound, particularly in combination with PD-1 blockers, and are looking forward to initiate clinical development later in the year", said Per Norlén CEO of Alligator Bioscience.

Alligator is planning to initiate an ATOR-1015 Phase I study during the second half of 2018.

A poster with the title "CTLA-4 x OX40 bispecific antibody ATOR-1015 induces anti-tumor effects through tumor-directed immune activation" is showcased today at 8-12 a.m. EDT and is also available on the company web page View Source

On April 17, 2018 Aptose Biosciences Inc. (NASDAQ:APTO) (TSX:APS) reported the presentation of preclinical data exploring the mechanism of action of APTO-253, the company’s clinical stage product candidate (Press release, Aptose Biosciences, APR 17, 2018, View Source;p=RssLanding&cat=news&id=2343016 [SID1234525432]). The data, demonstrating heightened sensitivity of BRCA1 or BRCA2 mutated cancer cells to APTO-253, were presented in a poster Tuesday, April 17 at the 2018 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting being held April 14-18, in Chicago, IL.

The poster, entitled APTO-253 is a new addition to the repertoire of drugs that can exploit DNA BRCA1/2 deficiency, explored the mechanism of action of APTO-253, a small molecule with anti-proliferative activity against cell lines derived from a wide range of human malignancies. This study investigated the mechanism of action of APTO-253 to identify synthetic lethal interactions that can guide combination drug studies.

The research team found that APTO-253 stabilizes certain quadruplex DNA structures, causes DNA damage, and exhibits synthetic lethality comparable to olaparib – an FDA-approved targeted therapy that acts against cancers in people with hereditary BRCA1 or BRCA1 mutations, including some ovarian, breast and prostate cancers – albeit through a different mechanism. Unlike other drugs for which loss of this DNA repair function results in hypersensitivity, APTO-253 does not produce myelosuppression even at the maximum tolerated dose. The observations reported also identify γH2AX as a potential biomarker of clinical effect and open the window to more detailed studies of how APTO-253 promotes DNA damage and how it might be used clinically to treat patients with tumors harboring deficiencies in DNA repair.

The presentation will be published in the AACR (Free AACR Whitepaper) Conference Proceedings. The poster can also be accessed here or at the Publications & Presentations section of the Aptose website, www.aptose.com.
"We have clarified the mechanism of APTO-253 during the past year or so, including its mechanism to inhibit expression of the MYC gene, an oncogene that promotes tumor growth and resistance to drugs in AML and other cancers," said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer. "AML remains our primary focus for APTO-253, and we hope to re-initiate dosing of AML patients with APTO-253 in an open phase Ib trial during the 2nd quarter of 2018. In the current presentation at AACR (Free AACR Whitepaper), we report that cancer cells deficient in the BRCA1/2 DNA repair functions are hyper-sensitive to APTO-253, analogous to the FDA-approved PARP inhibitor olaparib, but acting through a different mechanism. The findings reveal potential new solid tumor indications for APTO-253. Importantly, APTO-253 does not produce myelosuppression even at the maximum tolerated dose, which significantly distinguishes it from other cancer chemotherapies."

About APTO-253
APTO-253 is a clinical-stage small molecule targeted therapeutic agent that inhibits expression of the c-Myc oncogene, leading to cell cycle arrest and programmed cell death (apoptosis) in human-derived solid tumor and hematologic cancer cells, without causing general myelosuppression of the healthy bone marrow. The c-Myc oncogene is overexpressed in hematologic cancers, including acute myeloid leukemia (AML). Aptose researchers have reported the ability of APTO-253 to induce cell death, or apoptosis, in multiple blood cancer cell lines including AML, as well as in vitro synergy with various classes of conventional approved and investigational therapies for AML or myelodysplastic syndromes (MDS). New findings reveal that APTO-253 might also serve certain solid tumor patients with BRCA1/2 mutations, but without causing toxicity to the normal bone marrow functions.

On April 17, 2018 Johnson & Johnson reported a strong first quarter with $20 billion in sales that was fueled by significant growth in its pharmaceuticals business (Press release, BioSpace, APR 17, 2018, View Source [SID1234525487]).

About half of the healthcare giant’s quarterly sales was driven by the company’s pharma business. In its quarterly report, the healthcare giant said pharmaceutical sales generated $9.8 billion in the first quarter. That was an increase of 19.4 percent over the same period last year. The bulk of the company’s pharma sales were made overseas, according to the data. J&J said international sales increased by 33.1 percent and domestic sales increased 9.9 percent.

The company noted that strong sales were driven by drugs such as Darzalex (daratumumab), a treatment for multiple myeloma, Tremfya (guselkumab) a treatment for moderate to severe plaque psoriasis and blood-cancer treatment Imbruvica (ibrutinib). During the first quarter J&J filed a supplemental New Drug Application for Imbruvica as a treatment for Waldenström’s macroglobulinemia.

Johnson and Johnson noted other strong-performing drugs including Zytiga (abiraterone acetate), which is used for the treatment of metastatic, castration-resistant prostate cancer. During the quarter Zytiga gained approval for an additional indication as at treatment of metastatic high-risk castration-resistant prostate cancer. Two other strong performers included inflammatory disease treatment Stelara (ustekinumab) and the anti-blood clotting drug Xarelto.

Also, during the first quarter, J&J gained approval from the U.S. Food and Drug Administration for Erleada, an oral androgen receptor inhibitor for the treatment of patients with non-metastatic castration-resistant prostate cancer.

Johnson & Johnson noted that the pharmaceutical business gained a 7.6 percent boost from the company’s 2017 $30 billion acquisition of Swiss-based Actelion, which manufactures Tracleer, a drug used to treat pulmonary arterial hypertension a form of high blood pressure in the arteries of the lungs. While J&J saw an increase in earnings from the deal, the company noted that it discontinued development of one of the drug candidates picked up in that acquisition. In its earnings report, J&J said it terminated development of cadazolid, a Phase III program for the treatment of clostridium difficile-associated diarrhea. Months after the deal was announced Actelion disclosed that cadazolid saw mixed results in two identical studies. The drug hit the mark in reducing diarrhea in patients in one study but failed to do so in a joint-study.

Alex Gorsky, chief executive officer of Johnson & Johnson, said the company’s pharmaceutical business delivered robust returns for the company.

In addition to its strong pharma showing, J&J said its medical device business saw sales of $6.8 billion for the first quarter, which represented an increase of 7.5 percent over the prior year.

Not only did J&J see strong revenues from its pharma business, Gorsky added that the company is also benefitting from a revamping of U.S. tax laws. He said the new legislation that reduced corporate tax rates in the United States will allow the company to invest more than $30 billion in research and development, as well as capital investments over the next four years. Gorsky said that investment is an increase of 15 percent over the previous four years.
