Abstract:

Purpose::

Two studies in previously treated metastatic pancreatic cancer have been completed combining GVAX pancreas vaccine (GM-CSF–secreting allogeneic pancreatic tumor cells) with cyclophosphamide (Cy) and CRS-207 (live, attenuated Listeria monocytogenes–expressing mesothelin). In the current study, we compared Cy/GVAX followed by CRS-207 with (Arm A) or without nivolumab (Arm B).

Patients and Methods::

Patients with pancreatic adenocarcinoma who received one prior therapy for metastatic disease and RECIST measurable disease were randomized 1:1 to receive treatment on Arm A or Arm B. The primary objective was to compare overall survival (OS) between the arms. Additional objectives included assessment of progression-free survival, safety, tumor responses, CA19-9 responses, and immunologic correlates.

Results::

Ninety-three patients were treated (Arm A, 51; Arm B, 42). The median OS in Arms A and B were 5.9 [95% confidence interval (CI), 4.7–8.6] and 6.1 (95% CI, 3.5–7.0) months, respectively, with an HR of 0.86 (95% CI, 0.55–1.34). Objective responses were seen in 3 patients using immune-related response criteria (4%, 2/51, Arm A; 2%, 1/42, Arm B). The grade ≥3 related adverse event rate, whereas higher in Arm A (35.3% vs. 11.9%) was manageable. Changes in the microenvironment, including increase in CD8+ T cells and a decrease in CD68+ myeloid cells, were observed in long-term survivors in Arm A only.

Conclusions::

Although the study did not meet its primary endpoint of improvement in OS of Arm A over Arm B, the OS was comparable with standard therapy. Objective responses and immunologic changes in the tumor microenvironment were evident.

Author: Müller, Thomas ; Lemmens, Ed ; Nair, Nitya ; Jaffee, Elizabeth M. ; Brockstedt, Dirk G. ; Chang, Serena ; Whiting, Chan ; Chen, Shih-Yu ; Le, Dung T. ; Murphy, Aimee

Abstract:

The identification of biomarkers for patient stratification is fundamental to precision medicine efforts in oncology. Here, we identified two baseline, circulating immune cell subsets associated with overall survival in patients with metastatic pancreatic cancer who were enrolled in two phase II randomized studies of GVAX pancreas and CRS-207 immunotherapy. Single-cell mass cytometry was used to simultaneously measure 38 cell surface or intracellular markers in peripheral blood mononuclear cells obtained from a phase IIa patient subcohort (N = 38). CITRUS, an algorithm for identification of stratifying subpopulations in multidimensional cytometry datasets, was used to identify single-cell signatures associated with clinical outcome. Patients with a higher abundance of CD8+CD45RO−CCR7−CD57+ cells and a lower abundance of CD14+CD33+CD85j+ cells had improved overall survival [median overall survival, range (days) 271, 43–1,247] compared with patients with a lower abundance of CD8+CD45RO−CCR7−CD57+ cells and higher abundance of CD14+CD33+CD85j+ cells (77, 24–1,247 days; P = 0.0442). The results from this prospective–retrospective biomarker analysis were validated by flow cytometry in 200 patients with pancreatic cancer enrolled in a phase IIb study (P = 0.0047). The identified immune correlates provide potential prognostic or predictive signatures that could be employed for patient stratification.

Clinical Response of Live-Attenuated, Listeria monocytogenes Expressing Mesothelin (CRS-207) with Chemotherapy in Patients with Malignant Pleural Mesothelioma

Q1 · MEDICINE

Article

Author: Whiting, Chan C. ; Enstrom, Amanda ; Brockstedt, Dirk G. ; Murphy, Aimee L. ; Hassan, Raffit ; Kumar, Sushil ; Jaffee, Elizabeth ; McDougall, Katherine ; Coussens, Lisa M. ; Lemmens, Ed ; Tsujikawa, Takahiro ; Jahan, Thierry ; Nair, Nitya ; Honarmand, Somayeh ; Antonia, Scott ; Alley, Evan ; Choe, Gina ; Thomas, Anish ; Kindler, Hedy

Abstract:

Purpose::

Malignant pleural mesothelioma (MPM) is an aggressive cancer associated with poor prognosis. CRS-207 is a live-attenuated Listeria monocytogenes engineered to express mesothelin, a tumor-associated antigen highly expressed in MPM. CRS-207 induces antitumor immune responses and increases susceptibility of neoplastic cells to immune-mediated killing.

Patients and Methods::

Patients with unresectable MPM, ECOG 0 or 1, and adequate organ and pulmonary function were enrolled in this multicenter, open-label phase Ib study. They received two priming infusions of 1 × 109 CFU CRS-207, followed by pemetrexed/cisplatin chemotherapy, and CRS-207 booster infusions. Primary objectives were safety and induction of immune response. Secondary/exploratory objectives included tumor response, progression-free survival (PFS), overall survival (OS), immune subset analysis, and gene-expression profiling of tumor.

Results::

Of 35 evaluable patients, 89% (31/35) had disease control with one complete response (3%), 19 partial responses (54%), and 10 stable disease (29%). The estimated median duration of response was 5.0 months (95% CI, 3.9–11.5). The median PFS and OS were 7.5 (95% CI, 7.0–9.9) and 14.7 (95% CI, 11.2–21.9) months, respectively. Tumor size reduction was observed post–CRS-207 infusion prior to chemotherapy in 11 of 35 (31%) patients. No unexpected treatment-related serious adverse events or deaths were observed. IHC analysis of pre- and post–CRS-207 treatment tumor biopsies revealed possible reinvigoration and proliferation of T cells, increased infiltration of dendritic and natural killer cells, increased CD8:Treg ratio, and a shift from immunosuppressive M2-like to proinflammatory M1-like macrophages following CRS-207 administration.

Conclusions::

Combination of CRS-207 and chemotherapy induced significant changes in the local tumor microenvironment and objective tumor responses in a majority of treated patients.

Biologic Therapy Market Information: By Product and Geography - Global Forecast till 2025

NEW YORK, June 17, 2022 /PRNewswire/ -- One of the key factors driving the Biologic Therapy Market growth is the strong R&D pipeline. The efficiency of biologics in the treatment of severe infections, malignancies, and immunological and hormonal disorders is encouraging manufacturers to invest in R&D for the development of biologics. For instance, monoclonal antibodies constitute one of the fastest-growing segments amongst biological therapies. To date, 88 monoclonal antibodies have been approved for different indications. Some of the examples are ICT-107 for glioblastoma, VGX-3100 for cervical cancer, NeuVax for breast cancer, NexVax2 for celiac disease, CRS-207 for pancreatic cancer, PEV7 for recurrent vulvovaginal candidiasis, and GI-4000 for pancreatic cancer. Similar is the case of biologics meant to be used as vaccines and therapeutic proteins, the pipeline of vendors like AbbVie, Amgen, Johnson & Johnson, and F. Hoffmann-La Roche clearly indicate huge investments in R&D. Apart from manufacturers that are actively involved in research on biologics, many research institutes are also engaged in developing novel biologics through industrial collaborations. Technavio has announced its latest market research report titled Biologic Therapeutics Market by Product and Geography - Forecast and Analysis 2021-2025 Get more information on Macro & Micro Economic Factor Analysis, Statistical Tools, and Trend Projection at Affordable Pricing options. Learn More The Biologic Therapy Market value is set to grow by USD 226.61 billion, progressing at a CAGR of 11% from 2020 to 2025, as per the latest report by Technavio. Moreover, the market is segmented by product (antibody therapeutics, vaccines, cell therapy, gene therapy, and other therapies) and geography (North America, Europe, Asia, and ROW). Biologic Therapy Market 2021-2025: Segmentation Product Antibody Therapeutics Vaccines Cell Therapy Gene Therapy Other Therapies The biologic therapy market share growth by antibody therapeutics will be significant during the forecast period. Monoclonal antibodies are amongst the most widely sold biologics and are even referred to as the future of medicine. Monoclonal antibodies are cloned from single-parent cells and are designed to recognize and bind to specific receptors on the surface of the cells. This specificity in action makes monoclonal antibodies more effective than conventional treatments for immunological and chronic ailments like cancer. Owing to these factors, it is expected that the global biologic therapy market will grow during the forecast period. Geography North America Europe Asia ROW 57% of the market's growth will originate from North America during the forecast period. The US is the key market for biologic therapy in North America. Market growth in this region will be slower than the growth of the market in the Asia region. One of the reasons for market growth in the Americas is the increased incidence of chronic diseases. The rise in the prevalence of major health disorders is mainly due to lifestyle changes and increased consumption of alcohol and tobacco in the US. However, market growth is expected to be only gradual due to the patent expiry of major biologics present in the market. Biologic Therapy Market 2021-2025: Scope Biologic Therapy Market size Biologic Therapy Market trends Biologic Therapy Market analysis High cost of biologics is one of the key challenges hindering the biologic therapy market growth. Biologics can be used for the treatment of several types of malignancies, hormonal imbalances, and autoimmune conditions, but they are expensive, which makes them beyond the reach of the economically underprivileged. The total manufacturing costs, which include the costs related to the clinical trials associated with biologics, account for vendors offering these products at high costs. The development of a biological molecule requires a separate living organism. Though bacterial production is not that costly, the production of therapeutic agents like monoclonal antibodies and vaccines becomes costly as they involve animal handling. The immunization of the animal and other procedures related to the production of antibodies and vaccines increases the cost of that product. Due to the high price of biologic therapy, many patients are unable to access this effective therapy, and this will remain a major challenge for the market during the forecast period.

FDA Slaps Partial Hold on Bay Area Firm Aduro Biotech’s Cancer Vaccine Trial

October 24, 2016 By Mark Terry , BioSpace.com Breaking News Staff The U.S. Food and Drug Administration (FDA) placed a partial hold on Berkeley, Calif.-based Aduro Biotech ’s LADD trials. Aduro’s LADD technology is a method of engineering the bacteria Lysteria monocytogenes into therapeutics that stimulate targeted immune response to specific tumor antigens. The FDA didn’t specifically halt the trial, but paused new patient enrollment. The FDA hold was initiated after a blood culture sample on an indwelling port of a metastatic pancreatic cancer patient tested positive Listeria. The positive Listeria is suspected of being CRS-207. The patient presented with gastrointestinal symptoms, and was treated with intravenous antibiotics. As a result, subsequent blood cultures didn’t show signs of Listeria and the patient is recovering. All patients in the trial are continuing to receive treatment except one, who is on a pacemaker. The company stated, “Aduro is working with the FDA to lift the partial hold so as to resume new patient enrollment in its LADD clinical trials. The company is revising study protocols in accordance with feedback from the agency, including the modification of antibiotic administration following treatment, extended patient surveillance, and, as a pre-emptive measure, exclusion of patients who are on or will receive certain immune-suppressive treatments or who have certain prosthetic devices.” The LADD program uses live, attenuated double-deleted strains of Listeria monocytogenes that have been engineered to stimulate an innate immune response. They have also been engineered to express tumor-associated antigens, which causes the T-cells to attack specific tumors. CRS-207 is one of a group of product candidates in the LADD program that expressed the tumor-associated antigen mesothelin, which is over-expressed in various cancers, including mesothelioma and pancreatic, non-small cell lung, ovarian, endometrial and gastric cancers. The company has two other separate platform technologies, STING pathway activators and B-select monoclonal antibodies. The partial hold does not affect either of those platform programs. Aduro recently presented two posters at the Second CRI-CIMT-EATI-AACR International Cancer Immunotherapy Conference in New York. The first provided preclinical data in its LADD program showing positive changes in the tumor microenvironment and induction of a tumor-specific immune response. The second poster discussed its STING (Stimulator of Interferon Genes) Pathway Activator immunotherapy program. Both presentations indicated that the addition of a PD-1 blockade demonstrated significant antitumor efficacy. “These preclinical data demonstrate the underlying mechanisms by which our LADD and STING immunotherapy platforms activate the immune system and induce robust innate immunity, facilitating a change in the tumor microenvironment which results in effective destruction of cancer cells in several preclinical models,” said Thomas Dubensky, Jr. , Aduro’s chief scientific officer, in a statement. “Importantly, the combination data are even more impressive, showing increased efficacy when our LADD and STING platforms are combined with an anti-PD1 checkpoint inhibitor to combat the tumor’s ability to hide from the immune system. These data support our strategy to combine our immunotherapy regimens with checkpoint inhibitors for greater anti-tumor activity, looking toward the ultimate goal of better, more effective patient care.”

Aduro Biotech Opens New HQ in the Bay Area, Eventually to House 400 Workers

September 2, 2016 By Mark Terry , BioSpace.com Breaking News Staff If finding and developing drugs have long timelines for biotech companies, that can sometimes seem short and simple compared to finding biotech real estate space in the Bay Area. Berkley-based Aduro Biotech recently announced it had opened new corporate offices and laboratory facilities, a process that took almost two decades. The company’s LADD tech platform uses modified strains of the bacteria Listeria that have been engineered to express tumor-associated antigens that stimulate the immune system. It also has a STING Pathway Activator platform that activates, appropriately enough, the intracellular STING receptor, which also stimulates a tumor-specific immune response. In May, Aduro announced that its Phase IIb ECLIPSE trial for CRS-207 in pancreatic cancer patients failed to meet its primary endpoint. Despite that setback, the company in June presented data from an ongoing Phase Ib trial of CRS-207 in combination with pemetrexed and cisplatin in unresectable malignant pleural mesothelioma (PMP), which showed promise. Last year the company made an initial public offering that brought in $119 million. The company’s new headquarters are 110,853 square feet at 740 Heinz Avenue in West Berkeley. The San Francisco Business Times reported that it took the developer, Wareham Development, about 17 years to “win all the approvals for the West Berkeley building, on the site of a landmark former dried coconut warehouse.” “Over the course of the last two years, we have grown significantly, both in the number of programs and in our employee base, and we have outgrown our former location,” said Stephen Isaacs , Aduro’s chairman, president and chief executive officer, in a statement. “We are extremely pleased to remain in Berkeley, maintaining our roots and our key connections with both the University of California, Berkeley and this extraordinary community. Our new facility also provides room to grow as we continue to advance our three technology platforms focused on the development of immunotherapies that transform the treatment of challenging diseases.” The facility is the Aquatic Park Center, which is a development by Wareham Development. It is dubbed the largest research building in the East Bay since Wareham built the EmeryStation Greenway four years ago. So far, Aduro has built out three floors of the building for 110 staffers. By the end of the year it will host 200 employees, and ultimately have room for 400. “We really needed the space,” Isaacs told the San Francisco Business Times. In addition to its various internal projects, Aduro has partnerships with Johnson & Johnson , and with Incyte Corp. . Novartis (NVS) is utilizing its STING program. Currently the company has five preclinical drugs. The company had an open house on September 1, joined by Congresswoman Barbara Lee , Assemblymember Tony Thurmond , Councilmember Darryl Moore , Mayor Tom Bates and the Honorable Nancy Skinner . “Technology and innovation are helping to drive our economy forward,” Lee said in a statement. “As these new technologies are applied to healthcare, they are helping people live longer, healthier lives. I am pleased to know Aduro Biotech, a cutting-edge leader in immunotherapy, will remain in Berkeley and continue the East Bay’s tradition of world-leading innovation in healthcare and biotech.”
