"This month we expect to report additional data from our pivotal, global Phase 3 clinical trial of aldoxorubicin in patients with second-line soft tissue sarcomas (STS)," said Steven A. Kriegsman, CytRx’s Chairman and CEO. "We then plan to schedule a pre-NDA meeting with the FDA. Additionally, we recently completed enrollment in the aldoxorubicin Phase 2b clinical trial in second-line small cell lung cancer in September. We now estimate that top-line results will be available in the first half of 2017 as the number of progression events has not yet been reached."

Third Quarter 2016 and Recent Developments

Presented Positive Aldoxorubicin Combination Clinical Trial Results at ESMO (Free ESMO Whitepaper) 2016. On October 10, 2016, CytRx presented a poster at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2016 Congress featuring interim clinical data from its on-going clinical trial of aldoxorubicin in combination with ifosfamide and mesna in patients with soft tissue sarcomas. Of 36 evaluable patients, 13 of 36 (36%) achieved a partial response of the target lesion by RECIST 1.1 criteria, 22 of 36 (61%) had stable disease, and one patient had progressive disease. Median progression-free survival has not yet been reached. While the combination did have certain toxicities, none were treatment-limiting.

Completed enrollment in its Global Phase 2b Clinical Trial in Second-Line Small Cell Lung Cancer. On September 6, 2016, CytRx announced that it completed enrollment in its global, randomized Phase 2b clinical trial comparing aldoxorubicin to topotecan in 135 patients with small cell lung cancer (SCLC) who have progressed or relapsed to prior chemotherapy. The primary endpoint is progression-free survival. The number of progression events has not yet been reached, and CytRx currently expects to announce top-line data in the first half of 2017.

Strengthened the Balance Sheet with an Equity Financing. On July 20, 2016, CytRx completed a public offering of common stock and one-year warrants for total net proceeds of aproximately $18.3 million. If exercised in full, the warrants would provide up to an additional $20 million in capital.

Reported Initial Analysis of its Pivotal, Global Phase 3 Aldoxorubicin Trial in STS. On July 11, 2016, CytRx reported interim results from its global, randomized, Phase 3 clinical trial of aldoxorubicin compared to investigator’s choice therapy in patients with relapsed or refractory STS. The Company also previously announced that it expects to report additional data from the trial in the fourth quarter. Following the subsequent analysis, CytRx plans to schedule a pre-NDA meeting with the FDA to seek marketing approval. In addition, patients in the Phase 3 clinical trial continue to be followed for overall survival, a secondary endpoint of the trial.

Capital Conservation. During the third quarter, CytRx embarked on a plan to reduce spending until additional results from the aldoxorubicin Phase 3 STS clinical trial are available and the Company meets with the FDA. This included reducing headcount, stopping pre-commercialization activities for aldoxorubicin and suspending further development of DK049.

Pipeline Generation Activities. CytRx’s expanded its drug discovery efforts to create a pipeline of oncology candidates utilizing the Company’s LADRTM technology to attach ultra-high potency drugs to albumin (10-1000 times more potent than traditional chemotherapies limited to antibodies only) to target tumors.

Upcoming Milestones

Present interim data from the on-going Phase 1b/2 clinical trial of aldoxorubicin in combination with ifosfamide/mesna at the Connective Tissue Oncology Society (CTOS) Annual Meeting being held on November 9-12, 2016, in Lisbon, Portugal.
Announce additional data from CytRx’s pivotal, global Phase 3 clinical trial of aldoxorubicin in patients with second-line STS in November 2016.
Report top-line results from the global Phase 2b clinical trial evaluating aldoxorubicin versus topotecan in patients with second-line SCLC in the first half of 2017.
Schedule and hold a pre-NDA meeting with the FDA regarding aldoxorubicin as a treatment for patients with relapsed or refractory advanced STS.

Calithera Biosciences Reports Third Quarter 2016 Financial Results and Recent Highlights, and Raises Year-end Cash Guidance

On November 9, 2016 Calithera Biosciences, Inc. (Nasdaq:CALA), a clinical-stage pharmaceutical company focused on discovering and developing novel small molecule drugs directed against tumor and tumor immune cell metabolism targets for the treatment of cancer, reported its financial results for the third quarter ended September 30, 2016 (Press release, Calithera Biosciences, NOV 9, 2016, View Source;p=RssLanding&cat=news&id=2221119 [SID1234516512]). As of September 30, 2016, cash, cash equivalents and investments totaled $56.3 million.

"During the third quarter, we continued enrolling the two cohorts evaluating our glutaminase inhibitor CB-839 in triple negative breast cancer and in renal cell carcinoma. We expect to be in a position to provide additional updates at medical meetings in the fourth quarter," said Susan Molineaux, Ph.D., President and Chief Executive Officer of Calithera. "In addition, we opened two new immuno-oncology trials in the quarter, both of which should have an initial read out in 2017."

Third Quarter 2016 and Recent Highlights

CB-839: First patient enrolled and dosed in combination with checkpoint modulator. In August 2016, we enrolled the first patient in a Phase 1/2 clinical trial assessing the safety and efficacy of CB-839, in combination with Opdivo for the treatment of renal cell carcinoma (RCC), malignant melanoma and non-small cell lung cancer. The Phase 1/2 study will assess the safety, pharmacokinetics and pharmacodynamics of CB-839 and Opdivo. The study will enroll patients with clear cell RCC who are naïve to checkpoint inhibitors, as well as clear cell RCC, melanoma, and non-small cell lung cancer patients who are receiving anti-PD-1 monotherapy as their current therapy without having a tumor response.
CB-839: Data in renal cell carcinoma selected for oral presentation. In September, we announced that clinical data for CB-839 will be presented in a plenary session at the 28th Annual EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Symposium on Molecular Targets and Cancer Therapeutics, November 29 to December 2, 2016 in Munich, Germany. The clinical presentation will be focused on data from Calithera’s CB-839 Phase I RCC combination trial with everolimus.
CB-839: Data in triple negative breast cancer selected for presentation. Clinical data for CB-839 will be presented at the San Antonio Breast Cancer Symposium in San Antonio, December 6 to 10, 2016 in San Antonio, Texas. The clinical presentation will be focused on data from Calithera’s CB-839 Phase I triple negative breast cancer combination trial with paclitaxel.
CB-1158: First patient dosed in a phase 1 study of our first-in-class inhibitor of the immuno-oncology target arginase. In September 2016, we announced dosing of the first patient in a Phase I clinical trial assessing the safety and efficacy of our drug candidate as a treatment for advanced solid tumors. Arginase is an enzyme in myeloid-derived suppressor cells (MDSCs), which prevents T-cell and natural killer (NK) cell activation in tumors.
Board of Directors. In August 2016, Suzy Jones was appointed to our Board of Directors, and added to the Audit committee. Ms. Jones is currently Founder and Managing Partner of DNA Ink, a boutique life sciences advisory firm.
Selected Third Quarter 2016 Financial Results

Research and development expenses were $6.3 million for the three months ended September 30, 2016, compared with $6.8 million for the same period in the prior year. The decrease of $0.5 million was primarily due to the timing of manufacturing clinical supply to support our CB-839 and CB-1158 clinical trials, partially offset by increased personnel-related costs primarily due to higher headcount, salary increases and stock-based compensation expense, and costs associated with our licensing arrangements.

General and administrative expenses were $2.3 million for the three months ended September 30, 2016, compared with $2.2 million for the same period in the prior year. The increase of $0.1 million was primarily due to higher personnel-related costs as a result of higher headcount, salary increases and stock-based compensation expense.

Net loss for the three months ended September 30, 2016 was $8.5 million, or $0.44 per share.

Based on the results for the first nine months of 2016 and our current expectations for the remainder of the year, we are raising our guidance and expect cash, cash equivalents and investments will be at least $50 million at the end of 2016.

The higher expenses in the 2016 periods were primarily due to an increase in manufacturing and clinical expenses as a result of increased patient enrollment in the BPX-501 clinical trials, increased expenses for the IND-enabling activities for product candidates BPX-601 and BPX-701, and increased personnel and infrastructure costs.

General and administrative expenses were $4.3 million and $12.7 million for the three and nine months ended September 30, 2016, respectively, compared to $3.9 million and $8.9 million during the comparable periods in 2015. The higher expenses in the 2016 periods were primarily due to the growth of the organization, including an increase in costs related to personnel, higher facility costs and increased legal, accounting and travel related expenses.

Nektar Therapeutics Presents New Clinical Data from Ongoing Phase 1 Dose-Escalation Study of NKTR-214 at the Society for Immunotherapy of Cancer (SITC) 2016 Annual Meeting

On November 9, 2016 Nektar Therapeutics (Nasdaq: NKTR) reported that new Phase 1 clinical data for Nektar’s lead immuno-oncology agent, NKTR-214, were presented at the SITC (Free SITC Whitepaper) 2016 Annual Meeting (Press release, Nektar Therapeutics, NOV 9, 2016, View Source [SID1234516469]). NKTR-214 is an investigational immuno-stimulatory therapy designed to expand specific cancer-fighting T cells and Natural Killer (NK) cell abundance directly in the tumor micro-environment and increase expression of PD-1 on these immune cells. The results were presented by Adi Diab, MD, Assistant Professor, Department of Melanoma Medical Oncology, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center in an oral presentation during today’s session entitled "New Cancer Immunotherapy Agents in Development."

Interim results presented were from the ongoing Phase 1 dose-escalation, first-in-human, trial of single-agent NKTR-214 in patients with locally advanced or metastatic solid tumors, including melanoma, renal cell carcinoma (RCC), bladder, colorectal and other solid tumor cancers. A total of 20 patients were treated in four separate every three-week (q3w) dose cohorts (ranging from 0.003 mg/kg q3w to 0.012 mg/kg q3w) with 18 of these patients evaluable for anti-tumor activity. Based upon encouraging anti-tumor activity and tolerability of NKTR-214 observed at the 0.006 mg/kg q3w dose, an every two week (q2w) cohort of the 0.006 mg/kg dose began enrolling in September 2016 with an additional 5 patients enrolled to this cohort, all of which are continuing on therapy.

"NKTR-214 resulted in robust activation of the immune system and encouraging anti-tumor activity, including a partial response observed in a patient who continues to be treated with NKTR-214," said Dr. Ivan Gergel, Senior Vice President, Drug Development & Chief Medical Officer of Nektar. "NKTR-214 was also well tolerated in patients when administered as an every two-week or every three-week outpatient therapy. We are very encouraged by the clinical profile emerging for NKTR-214 and the totality of the data from this ongoing single-agent trial of NKTR-214."

Preliminary encouraging evidence of anti-tumor activity has been observed to date in the ongoing study:

12/18 (67%) evaluable patients had stable disease at the initial 8 week scan
7/18 (39%) evaluable patients had radiographic reductions in tumor size per RECIST 1.1 on NKTR-214
One patient with metastatic melanoma (prior treatment with ipilimumab and a BRAF inhibitor) has received 13 cycles of treatment (0.003 mg/kg q3w) with stable disease and continues on therapy with NKTR-214
In the 18 evaluable patients, a total of 5 patients with metastatic RCC who had progressed on 1 prior tyrosine kinase inhibitor (TKI) were treated with NKTR-214 at the 0.006 mg/kg q3w dose level:
1/5 (20%) of these RCC patients had a uPR per RECIST 1.1 (at 16 week scan) and treatment with NKTR-214 is ongoing
2/5 of these RCC patients had additional tumor reductions of 6% and 10% per RECIST 1.1 while on NKTR-214
NKTR-214 also demonstrated a favorable safety and tolerability profile with convenient, outpatient q2w or q3w administration in 25 patients evaluable for safety to-date:

No immune-related AEs were observed (e.g. colitis, dermatitis, hepatitis pneumonitis, adrenal insufficiency)
No deaths or grade 4 AEs related to NKTR-214
No capillary leak syndrome was observed at any dose
One patient experienced a dose-limiting toxicity (DLT) of hypotension/syncope at 0.012 mg/kg q3w and continued on treatment at 0.006 mg/kg q3w
3/25 patients experienced grade 3 hypotension, which was rapidly reversed with fluid administration and all patients continued on treatment with NKTR-214
Most common grade 1-2 adverse events were fatigue, pruritis, cough, decreased appetite, pyrexia, and hypotension
Immune pheno-typing was conducted and biomarkers of immune activation were measured in patients with evaluable tumor biopsies and blood samples. Treatment with NKTR-214 produced a robust elevation in immune cell frequency and activation, including:

Increase in total and newly proliferating (Ki67+) CD4+ T cells, CD8+ T cells, and Natural Killer (NK) cells in 9/9 patients with blood samples evaluated in the trial to-date, with increases of up to 30-fold observed
Increase in frequency of PD-1+ T cell subsets of up to 9-fold in the blood
Increase in CD8+ T cells and Natural Killer (NK) cells of up to 10-fold in the tumor micro-environment in patients with evaluable tumor biopsies (pre-dose and post-dose at week 3), with minimal intratumoral changes to T regulatory cells
Increase in expression of cell-surface PD-1 on T cell subsets of up to 2-fold in the tumor micro-environment
Induction of an activation gene signature in the tumor micro-environment, including increases of 5-fold or greater in expression of interferon γ, perforin and granzyme B genes
Changes in T cell repertoire (TCR), which is a measure of T cell clonality, in the tumor micro-environment
"We are extremely pleased with the single-agent activity of NKTR-214 and the potential of NKTR-214 to transform the immuno-oncology landscape," said Howard W. Robin, President & CEO of Nektar Therapeutics. "As the first I-O agent to demonstrate that it can increase tumor-infiltrating lymphocytes (TILs) and increase PD-1 expression on immune cells in humans, NKTR-214 complements not only existing checkpoint inhibitors, such as nivolumab, but also other I-O mechanisms in development."

In September 2016, Nektar entered into a clinical collaboration with Bristol-Myers Squibb to evaluate NKTR-214 as a potential combination treatment regimen with Bristol-Myers Squibb’s Opdivo (nivolumab) in five tumor types and seven potential indications. The Phase 1/2 clinical trials will enroll up to 260 patients and will evaluate the potential for the combination of Opdivo (nivolumab) and NKTR-214 to show improved and sustained efficacy and tolerability above the current standard of care in melanoma, kidney, triple-negative breast cancer, bladder and non-small cell lung cancer patients. The initial dose-escalation trial is underway with Opdivo (nivolumab) and NKTR-214.

NKTR-214 is an experimental therapy designed to stimulate cancer-killing immune cells in the body by targeting CD122 specific receptors found on the surface of these immune cells, known as CD8+ effector T cells and Natural Killer (NK) cells. In preclinical studies, treatment with NKTR-214 resulted in a rapid expansion of these cells and mobilization into the tumor micro-environment.1 NKTR-214 has an antibody-like dosing regimen similar to the existing checkpoint inhibitor class of approved medicines. A Phase 1/2 clinical study is ongoing to evaluate single-agent NKTR-214 in cancer patients.

Aduro Biotech’s Personalized LADD Therapy Featured in an Oral Presentation at SITC’s New Cancer Immunotherapy Agents in Development Program

On November 9, 2016 Aduro Biotech, Inc. (Nasdaq:ADRO), a biopharmaceutical company with three distinct immunotherapy technologies, reported that Tom Dubensky Jr., Ph.D., chief scientific officer of Aduro, presented today about the company’s personalized LADD technology at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) distinct session titled New Cancer Immunotherapy Agents in Development being held in conjunction with the SITC (Free SITC Whitepaper) annual meeting (Press release, Aduro BioTech, NOV 9, 2016, View Source;p=RssLanding&cat=news&id=2221061 [SID1234516456]).

LADD is Aduro’s proprietary platform of live, attenuated double-deleted Listeria monocytogenes strains that have been engineered to express tumor-associated antigens to induce an innate immune response and tumor-specific T cell-mediated immunity. Personalized LADD, or pLADD, is a second generation LADD technology that is being designed for individualized, patient-specific immunotherapy. The pLADD approach leverages the immune activating activity of the Listeria bacterial vector in combination with neoantigens, or the tumor markers specific to an individual’s cancer, which are derived from the patient’s own unique tumor cells. Once administered, pLADD therapies are expected to mobilize the immune system through first an immediate recognition of the presence of Listeria as being foreign and then second a specific and customized immune attack on cells containing the tumor neoantigens presented by pLADD. An Investigational New Drug (IND) application has been accepted, and a Phase 1 trial evaluating the safety and immunogenicity of pLADD in patients with advanced gastro-intestinal cancers is planned.

"There is tremendous excitement in the oncology field to develop personalized therapies as the next new wave in immunotherapy to specifically customize treatment for each patient based on neoantigens that are unique to a patient’s tumor," said Tom Dubensky Jr., Ph.D., chief scientific officer of Aduro. "We are excited about the potential of our pLADD program, which has been shown to induce anti-tumor immune responses specific to tumor neoantigens and correlate with longer survival in preclinical models. Additionally, in these models, we observed a synergistic anti-tumor effect when pLADD was combined with an anti-PD-1 antibody, resulting in a significant reduction in tumor volume and increased survival."

The pLADD technology platform is well-suited to maximize the potential benefit of personalized therapy through the ability to engineer the therapy with multiple tumor-specific neoantigens, as well as to leverage an efficient small-scale manufacturing process in its production.

To create a patient-specific pLADD therapy, a physician begins by removing tumor cells from the patient. These cells are analyzed in order to molecularly characterize (sequence) the tumor, including any mutations that are unique to the patient’s own tumor cells. Predictive algorithms for antigen processing are run to identify pertinent tumor antigens. Aduro then creates a LADD strain that includes the patient-specific neoantigens for administration.

Preclinical Data with pLADD
Preclinical data showed that pLADD induced a robust immune response, including broad innate immune responses involving cytokines, chemokines, natural killer, and gamma delta T cells, as well as antigen-specific adaptive T cell responses (CD8+ and CD4+). In preclinical models, pLADD remodeled the tumor microenvironment, whereby an increase in infiltration of neutrophils, T cells and dendritic cells was observed. The combination of pLADD with an anti-PD-1 led to a sustained immune response and significant prolongation of survival in these models.

Detailed preclinical data will be presented by Aduro scientist Meredith Leong, Ph.D., on Saturday, November 12, 2016 at the SITC (Free SITC Whitepaper) Annual Meeting (Poster #366).
