"Nkarta continues to set the pace for NK cell therapy as we build on the strengths of our next generation platform and advance our two co-lead clinical programs," said Paul J. Hastings, President and Chief Executive Officer of Nkarta. "During the period, we initiated collaboration activities with CRISPR Therapeutics, added new platform capabilities for rapid innovation, and expanded our manufacturing footprint – all designed to stay ahead of the technology curve and transform the scientific insights of cell therapy into meaningful medicines for cancer patients. Nkarta remains on track to report initial clinical data from our Phase 1 study of NKX101 by the end of this year."

RECENT ACCOMPLISHMENTS AND FUTURE MILESTONES

NKX101

Nkarta aims to present initial clinical data from its ongoing clinical trial of NKX101 by year end 2021. In the Phase 1 study, patients receive multiple doses of NKX101 during a 28-day treatment cycle and are eligible to receive subsequent cycles of treatment upon evidence of tolerability and disease response.
NKX019

Nkarta expects patient dosing in a Phase 1 clinical trial of NKX019 to initiate in the second half of 2021 and has begun manufacturing of clinical supply of NKX019 at its in-house cGMP clinical manufacturing facility in South San Francisco, California.
Manufacturing

Nkarta entered a lease agreement to establish a combined manufacturing facility and company headquarters. The manufacturing facility will produce materials for potential pivotal trials and commercial launch of multiple engineered NK cell therapy products. The expanded manufacturing footprint, centered in South San Francisco, California, builds upon Nkarta’s existing 2,700 square foot cGMP clinical manufacturing facility.
Pipeline and Platform

In May 2021, Nkarta and CRISPR Therapeutics announced a research and development collaboration to co-develop and co-commercialize two chimeric antigen receptor (CAR) NK cell product candidates, one targeting CD70, and one combining NK and T cells (NK+T), each enhanced with genome engineering. The collaboration also gives Nkarta a license to CRISPR/Cas9 gene editing technology for use in its own engineered NK cell therapy products.

Nkarta continues to integrate important scientific insights, processes and breakthroughs into its next generation platform. Platform capabilities include:

Multiplexed CRISPR/Cas9 genome engineering
"Armored" cells with membrane-bound IL-15 for persistence

About NKX101
NKX101 is an investigational, off-the-shelf cancer immunotherapy that uses natural killer (NK) cells derived from the peripheral blood of healthy donors and engineered with membrane-bound IL15 and a chimeric antigen receptor (CAR) targeting NKG2D ligands on tumor cells. NKG2D, a key activating receptor found on naturally occurring NK cells, induces a cell-killing immune response through the detection of stress ligands that are widely expressed on cancer cells. By engineering NKX101 with the proprietary NKG2D-based CAR, the ability of NK cells to recognize and kill tumor cells in pre-clinical models is increased significantly compared to non-engineered NK cells. The addition of membrane-bound IL15, a proprietary version of a cytokine for activating NK cell growth, has been shown in pre-clinical models to enhance the proliferation, persistence and sustained activity of NK cells. A multi-center Phase 1 clinical trial of NKX101 in patients with relapsed/refractory acute myeloid leukemia (AML) or higher risk myelodysplastic syndromes (MDS) is currently enrolling. Additional information about the clinical trial is available on ClinicalTrials.gov, identifier NCT04623944.

About NKX019
NKX019 is an investigational, off-the-shelf cancer immunotherapy that uses natural killer (NK) cells derived from the peripheral blood of healthy donors and engineered with a CD19-directed chimeric antigen receptor (CAR) and a proprietary, membrane-bound form of interleukin 15 (IL-15). CD19 is a biomarker for normal and malignant B cells, and it is a validated target for B cell cancer therapies. Via its CAR, NKX019 targets and binds to CD19 and eliminates CD19-expressing cells via a robust immune response in preclinical studies. Preclinical models also demonstrate enhanced proliferation, persistence and activity of NK cells with the membrane-bound IL-15, an important cytokine for NK cell survival. Initiation of a Phase 1 clinical trial of NKX019 in patients with relapsed/refractory B cell malignancies in multiple centers in the United States and Australia is planned for the second half of 2021.

About Nkarta’s Platform and Natural Starting Materials
Nkarta’s engineering platform utilizes healthy adult donors as the source for NK cells. By enlisting this natural source of NK cells, Nkarta starts with bona fide NK cells endowed with inherent tumor-recognizing ability and potent cytotoxic function. Healthy donor-derived NK cells are also available in abundance, providing a large quantity of cells with which to begin the efficient two-week manufacturing process. Finally, healthy donor-derived adult cells consist of a diverse repertoire of NK cells, providing Nkarta with the potential to capitalize on the inherent diversity of the innate immune system in selecting donors or NK cell populations with optimal characteristics.

About Nkarta’s NK Cell Technologies
Nkarta has pioneered a novel discovery and development platform for the engineering and efficient production of allogeneic, off-the-shelf natural killer (NK) cell therapy candidates. The approach harnesses the innate ability of NK cells to recognize and kill tumor cells. To enhance the inherent biological activity of NK cells, Nkarta genetically engineers the cells with a targeting receptor designed to recognize and bind to specific proteins on the surface of cancerous cells. This receptor is fused to co-stimulatory and signaling domains to amplify cell signaling and NK cell cytotoxicity. Upon binding the target, NK cells become activated and release cytokines that enhance the immune response and cytotoxic granules that lead to killing of the target cell. All of Nkarta’s NK current cell therapy candidates are also engineered with a membrane-bound IL15, a proprietary version of a cytokine known for activating NK cell growth, to enhance the persistence and activity of the NK cells.

Nkarta’s manufacturing process generates an abundant supply of NK cells that, at commercial scale, is expected to be significantly lower in cost than other current allogeneic and autologous cell therapies. Key to this efficiency is the rapid expansion of donor-derived NK cells using a proprietary NKSTIM cell line, leading to the production of hundreds of individual doses from a single manufacturing run. The platform also features the ability to freeze and store CAR NK cells for an extended period of time and is designed to enable immediate, off-the-shelf administration to patients at the point of care.

On August 12, 2021 Silverback Therapeutics, Inc. (Nasdaq: SBTX) ("Silverback"), a clinical-stage biopharmaceutical company leveraging its proprietary ImmunoTAC technology platform to develop systemically delivered, tissue targeted therapeutics for the treatment of cancer, chronic viral infections, and other serious diseases, reported financial results for the second quarter ended June 30, 2021 and provided a business update (Press release, Silverback Therapeutics, AUG 12, 2021, View Source [SID1234586445]).

Second Quarter Financial Results

For the second quarter ended June 30, 2021, Silverback reported a net loss of $24.5 million, compared to a net loss of $6.5 million for the comparable period in 2020. For the six months ended June 30, 2021, Silverback reported a net loss of $43.4 million, compared to a net loss of $11.7 million for the comparable period in 2020. Included in the net losses for the three and six months ended June 30, 2021 were $4.7 million and $9.0 million of non-cash stock-based compensation compared to $128,000 and $175,000 for the same periods in 2020.

Research and development expenses for the second quarter ended June 30, 2021 were $17.7 million, compared to $5.1 million for the same period in 2020. Research and development expenses for the six months ended June 30, 2021 were $30.0 million compared to $9.5 million for the same period in 2020. The increases in the Company’s research and development expenses in 2021 were primarily attributable to the advancement of pipeline programs, including SBT6290 and SBT8230, through preclinical development and the continued clinical development of SBT6050. Silverback also incurred additional personnel-related expenses as operations grew in support of program advancements.

General and administrative expenses for the second quarter ended June 30, 2021 were $6.8 million, compared to $1.3 million for the same period in 2020. General and administrative expenses for the six months ended June 30, 2021 were $13.4 million, compared to $2.2 million for the same period in 2020. The increases in general and administrative expenses were primarily attributable to an increase in personnel-related expenses due to increased headcount in 2021, including new executives, as well as increases in salaries, bonuses, and stock-based compensation. The increases in general and administrative expenses were also due to an increase in legal fees, professional fees, and other various general and administrative expenses as we now operate as a public company.

As of June 30, 2021, Silverback reported cash and cash equivalents of $359.7 million, compared to $386.6 million at December 31, 2020, which is expected to fund operating expenses and capital expenditure requirements for at least the next 24 months.

"I am pleased with the progress made over the course of the past quarter, of particular note, in the clinical development program for Annamycin, our next-generation anthracycline. We are committed to advancing our three core technologies to meet the needs in a number of oncology and viral indications. We believe the next 18 months hold a number of key inflection points and value drivers for the Company. We believe Moleculin is well-positioned to continue building momentum and drive shareholder value in the near- and long-term," commented Walter Klemp, Chairman and CEO of Moleculin.

Recent Highlights

Received approval to extend dose escalation in Phase 1/2 European clinical trial evaluating Annamycin for the treatment of acute myeloid leukemia (AML).
Commenced enrollment and dosed the first subject in its U.S. Phase 1b/2 clinical trial evaluating Annamycin for the treatment of soft tissue sarcoma (STS) lung metastases.
Held further meetings with the MHRA in the UK regarding a healthy volunteer trial with WP1122 for the treatment of COVID-19.
Programs Update

Next Generation Anthracycline – Annamycin

Annamycin, the Company’s next-generation anthracycline was designed to be noncardiotoxic (unlike all currently approved anthracyclines) and has demonstrated its lack of cardiotoxicity in recently conducted human clinical trials for the treatment of AML. The Company believes that, because of this unique improvement in safety, the use of Annamycin may not face the same usage limitations imposed on doxorubicin. Additionally, Annamycin has been shown in animal models to accumulate in the lungs at up to 30-fold the level of doxorubicin. Annamycin is currently in development for the treatment of AML and STS lung metastases. For more information about the Phase 1b/2 study evaluating Annamycin for the treatment of STS lung metastases, please visit clinicaltrials.gov and reference identifier NCT04887298.

Upcoming Milestones Expectations

H2 2021: Report cohort topline results from the ongoing Phase 1/2 study for treatment of AML and report the study’s topline results.
H2 2021: Commence Phase 1/2 study in Europe for the treatment of AML evaluating combination therapy of Annamycin + AraC.
H2 2021: Commencement of an investigator-funded, second Phase 1b/2 clinical trial of Annamycin in sarcoma lung metastases in Europe
First-in-class p-STAT3 Inhibitors – WP1066 and WP1220

WP1066 is one of several Immune/Transcription Modulators, designed to stimulate the immune response to tumors by inhibiting the errant activity of Regulatory T-Cells (TRegs) while also inhibiting key oncogenic transcription factors, including p-STAT3 (phosphorylated signal transducer and activator of transcription 3), c-Myc (a cellular signal transducer named after a homologous avian virus called Myelocytomatosis) and HIF-1α (hypoxia inducible factor 1α). These transcription factors are widely sought targets that are believed to contribute to an increase in cell survival and proliferation, and the angiogenesis (coopting vasculature for blood supply), invasion, metastasis and inflammation associated with tumors. They may also play a role in the inability of immune checkpoint inhibitors to affect more resistant tumors. WP1220 is a close analog to WP1066 that the Company has developed as a potential topical therapy for skin-related diseases.

WP1220 was evaluated for the treatment of Cutaneous T-Cell Lymphoma (CTCL) and, based on those results, we are seeking collaborators for future development. WP1066 is currently being evaluated for the treatment of pediatric brain tumors, including Diffuse Interstitial Pontine Glioma (DIPG). Additionally, WP1066 + radiation is being evaluated, pre-clinically, in the treatment of Glioblastoma Multiforme (GBM).

Upcoming Milestones Expectations

H2 2021: File a US Investigative New Drug application (IND) for the treatment of certain adult cancer(s) with WP1066 and identify an institution to commence an associated investigator-funded Phase 1a/1B study.
H2 2021: Continue support of the physician-sponsored pediatric brain tumor clinical trial
H1 2022: Facilitate launch of physician-sponsored Phase 2 study of WP1066 for the treatment of pediatric brain tumors including DIPG.
Actively seek collaboration with a strategic partner in the near term for external funding for the continued development of WP1220 in a Phase 2 clinical trial as a topical therapy for CTCL.
Infectious Disease and Metabolism/Glycosylation Inhibitors- WP1122, WP1096 and WP1097 Portfolio

Moleculin has new compounds designed to target the roles of glycolysis and glycosylation in both cancer and viral diseases. The Company’s lead Metabolism/Glycosylation Inhibitor, WP1122, is a prodrug of 2-DG that appears to improve the drug-like properties of 2-DG by increasing its circulation time and improving tissue/organ distribution. Recent published research has identified that 2-DG has antiviral potential against SARS-CoV-2 in vitro and, based on publicly available information, a recently completed Phase 2 clinical trial by an unrelated company in India has reported efficacy in COVID-19 patients, resulting in the Emergency Use Authorization of 2-DG by the Drugs Controller General of India. Moleculin believes WP1122 has the potential to become an important drug to potentiate existing therapies, including checkpoint inhibitors. The Company recently engaged in discussions with the Medicines and Healthcare Products Regulatory Agency (MHRA) in the United Kingdom (UK) regarding the potential for beginning clinical trials of WP1122 without the need for additional preclinical animal efficacy models. Based on their initial discussions with the MHRA, the Company believes that a COVID-19 animal model will not be required in order to submit a clinical trial application (CTA) for a Phase 1 clinical trial beginning with healthy volunteers in that country, although no final determination has been made by the MHRA. During the second quarter these discussions continued. Additionally, the Company is in the process of identifying countries where potential future Phase 2 clinical studies could occur. The Company is also engaged in preclinical development of additional antimetabolites (WP1096 and WP1097) targeting glycolysis and glycosylation.

Upcoming Milestones Expectations

H2 2021: Seek to initiate Phase 1a/1b study of WP1122 for the treatment of COVID-19 in the UK.
H2 2021: Potential to launch Phase 2 pivotal study of WP1122 for the treatment of COVID-19 outside the U.S.
H2 2021: File an IND in the U.S. for the treatment of certain cancers such as GBM and pancreatic cancer, with WP1122.
Ongoing preclinical development work in anti-viral indications such as HIV, Zika, and Dengue. IND targeted for 2022.

With respect to Centurion Biopharma, Mr. Kriegsman and Lead Director Louis Ignarro, PhD continued pursuing strategic partnership opportunities to advance clinical testing for the platform’s assets. Discussions with prospective partners under confidentiality agreements are ongoing. There are no formal updates to report at this time.
CytRx maintains federal and state net operating loss ("NOL") carryforwards of $327.6 million and $252.6 million, respectively, available to offset against future taxable income. Of this amount, $258.3 million of federal NOLs and $252.6 million of state NOLs are unrestricted.
ImmunityBio Highlights

ImmunityBio announced during the quarter that Cohort C of its QUILT 88 study in pancreatic cancer, which includes aldoxorubicin and patients who have previously failed two lines of standard-of-care therapy, is expected to be completed in the third quarter of 2021. An early readout of survival data is expected in the first quarter of 2022.
Orphazyme Highlights

Orphazyme announced during the quarter that it received a Complete Response Letter ("CRL") from the Food and Drug Administration ("FDA") following its review of the new drug application for arimoclomol. Orphazyme disclosed that the FDA issued the CRL based on needing additional evidence to further substantiate the validity and interpretation of the 5-domain NPC Clinical Severity Scale and, in particular, the swallow domain. Further, the FDA noted in the CRL that additional data is needed to bolster confirmatory evidence beyond the single phase 2/3 clinical trial to support the benefit-risk assessment of the NDA.
Subsequently, Orphazyme announced 24-month interim results of an open-label extension ("OLE") trial of arimoclomol for the treatment of NPC. Orphazyme provided efficacy and safety data for its investigational treatment arimoclomol in NPC for up to 36 months. The results demonstrate that arimoclomol provided a sustained benefit to study participants by reducing NPC progression as measured by the 5-domain NPC Clinical Severity Scale (5D-NPCCSS).
Orphazyme is expecting prospective European regulatory approval for arimoclomol in the treatment of NPC by the end of 2021.

On August 12, 2021 Evaxion Biotech A/S (NASDAQ: EVAX) ("Evaxion" or the "Company"), a clinical-stage biotechnology company specializing in the development of AI-driven immunotherapies to improve the lives of patients with cancer, bacterial diseases and viral infections, reported the second quarter 2021 financial results and provided an operational update (Press release, Evaxion Biotech, AUG 12, 2021, View Source [SID1234586414]).

Lars Wegner, CEO of Evaxion, said: "Evaxion has made very encouraging clinical progress in the second quarter of 2021, reporting data in July which we believe support advancing both of our lead programs into Phase 2b trials. Phase 1/2a data on our lead program EVX-01 showed that 67% of the patients benefited from EVX-01 in combination with anti-PD-1 for the treatment of metastatic melanoma, compared to the historical data of only 40% benefiting from the check point inhibitor alone. In addition, EVX-02 showed T-cell activation in adjuvant melanoma and appeared to be well tolerated. We plan to initiate a Phase 2b trial for EVX-01 in melanoma in December 2021 and initiate a Phase 2b trial of EVX-02, in conjunction with our third program, EVX-03, in Q2 2022. We also reported preclinical proof of concept data for our RAVEN AI platform for vaccine design and development for viral infections, which we believe has the potential to make a significant contribution in addressing coronavirus infections and other viral diseases. Our cash reserves of $18.8 million provide a solid financial foundation and will facilitate the continued development of these four lead programs."

Operational and Business Highlights in Q2 2021

Reported preclinical proof of concept data in June for the Adaptive and Intelligent Vaccine for a Rapid Response against Corona Viruses (AICoV) program, supporting next-generation coronavirus vaccine technology. First-generation SARS-COV-2 vaccines are focused on the generation of neutralizing antibodies by B cells that bind to the spike protein of the virus and inhibit infection. Activation of T cells may help broaden the immune system’s response to coronavirus and protect against mutations on the spike protein that have been shown to circumvent immunity. Early data demonstrate our RAVEN platform identifies novel immunogenic T-cell epitopes beyond just the spike protein. The proof-of-concept data show RAVEN’s potential to rapidly support the design of novel SARS-COV-2 vaccines capable of tackling newly emerging coronavirus variants.
EVX-03, a novel patient-specific therapy for multiple cancer indications and EVX-B1, a vaccine for the prevention of Staphylococcus aureus including MRSA, continue to progress as expected through preclinical and Chemistry, Manufacturing and Controls (CMC) development.
Presentation in April at the 4th Neoantigen Summit Europe, described Evaxion’s recent improvement in determining cancer neoepitopes through measurement and prediction of peptide-MHC (pMHC) complex stability. We believe this is a significant improvement over AI models trained on traditional mass spectrometry ligand data and the data have already proven valuable in improving our discovery and design of patient-specific neoepitopes used to derive our cancer therapies.
Acceptance of a scientific paper by the International Conference on Machine Learning describing a novel predictive system based on deep probabilistic programming that enables the rapid conversion of sequence data into structural information on protein fragments, which we believe may be useful for drug and vaccine design.
Events after the Reporting Period

Reported new clinical data in early July from Phase 1/2a trials of EVX-01 and EVX-02.
EVX-01, our peptide-based patient-specific cancer therapy, demonstrated anti-tumor effect in combination with anti-PD-1 treatment, a checkpoint inhibitor anticancer drug, for metastatic melanoma. Results from the combination therapy compares favorably to historical data from anti-PD-1 treatment alone. A Phase 2b trial of EVX-01 is planned to start in December 2021.
Preliminary data with EVX-02, our DNA-based patient-specific cancer therapy, demonstrated T-cell activation induced by EVX-02 and appeared to be well tolerated. A Phase 2b trial of EVX-02, in combination with EVX-03, our novel patient-specific therapy for multiple cancer indications, is planned to start in Q2 2022 as a combination therapy with anti-PD-1 in adjuvant melanoma.
Expected milestones in 2021 & 2022

Phase 2b trial initiation of EVX-01 in metastatic melanoma – Q4 2021.
Phase 2b trial regulatory filing for EVX-02 in combination with EVX-03 in adjuvant melanoma – Q2 2022.
Phase 1a trial regulatory filing for EVX-B1 for S. aureus in skin and soft tissue infections (SSTIs) – H2 2022.

Research and Development expenses were $5.1 million for the quarter ended June 30, 2021, compared to $2.6 million for the same period in 2020. The increase of $2.5 million was primarily related to increased spending, net of grant income, for ongoing development utilizing our AI platforms, preclinical product candidates, and clinical trials. In addition, employee-related costs increased due to higher headcount.
General and Administrative expenses were $1.9 million for the quarter ended June 30, 2021, compared to $1.4 million for the same period in 2020. The increase of $0.5 million was primarily related to increases in overhead and professional fees related to the expansion of our corporate function.
