Under the terms of the deal, Peter MacCallum senior research fellow Professor Philip Darcy will lead a team of researchers undertaking preclinical development of Prescient’s OmniCAR programs.

OmniCAR is a next generation CAR-T platform designed to improve the safety, effectiveness, and control of existing CAR-T treatments.

CAR-T treatments involve extracting and genetically modifying T cells within a patient’s immune system to better identify and attack cancerous cells.

The modified cells are then ‘expanded’ (replicated to create more) and infused back into the patient, where they recognise and eliminate cancer.

Professor Darcy said: "We are excited by the opportunity and potential offered by the OmniCAR platform to make headway into solid tumours and other blood cancers, and to greatly enhance and improve the clinical control and efficacy of existing CAR-T cancer therapies."

This agreement will see the two organisations focus on developing next generation CAR-T products using the OmniCAR technology for three types of cancer: acute myeloid leukemia (AML), Her2+ solid tumors, and glioblastoma multiforme (GBM).

Steven Yatomi-Clarke, CEO of Prescient, said the company is committed to completing the development work both quickly, and to the highest standards.

"Our latest research program with Peter Mac is an important part of our development plans, which include institutional and commercial laboratories," he said.

"We continue to work very closely with Professor Darcy and the team at Peter MacCallum as we progress this exciting development of controllable and adaptable next generation CAR-T therapies."

The resulting intellectual property will be owned by Prescient Therapeutics.

This agreement marks the second research collaboration between the two organisations, having announced a similar agreement focusing on Cell Therapy Enhancement programs last year.

Prescient increases dosage in separate clinical trial
The deal comes hot on the heels of a dosage increase in Prescient’s Phase 1b clinical study of its oncology drug PTX-200 and cytarabine in patients with AML.

PTX-200 is a ‘novel domain inhibitor’, which works to inhibit an important tumor survival pathway known as ‘Akt’ and is currently in clinical trials for a range of cancers including HER2-negative breast cancer and persistent platinum-resistant ovarian cancer.

Three AML patients were being treated with 35mg/m2 with no ‘dose limiting’ toxicities being reported, and no other clinical responses recorded.

Following a safety review of this data, Prescient is now looking to enrol a new cohort to test the drug at a dosage of 45mg/m2.

Dr Terrence Chew, the company’s Chief Medical Officer, said the results of the 35mg/m2 tests are promising.

"AML remains a very difficult disease to treat, especially in the relapsed and refractory setting, with patients often too sick to endure vigorous treatment," he said.

"It is therefore pleasing to see the completion of this cohort without dose limiting toxicities."

AML affects approximately 158,000 people worldwide, and inhibits the formation of new blood cells.

1. Posting of Extraordinary Loss and Its Details With regard to the impact of the severe cold wave that struck many parts of the United States in mid-February 2021, in its March 10, 2021 press release "Notice Regarding the Impact of a Cold Wave in the United States," Kuraray announced that a number of Group manufacturing sites located in a Houston, Texas, suburb and run by local subsidiary Kuraray America, Inc., suspended operations from Mid-February onward. Full production, except for certain lines, resumed as of April 2, 2021 as announced in a subsequent press release issued on the same date. Having assessed the impact of the cold wave on its consolidated operating results, Kuraray recorded an extraordinary loss of ¥3,016 million as a disaster loss for the first quarter of the fiscal year ending December 31, 2021.

2. Revisions to consolidated earnings forecast for the second quarter of fiscal 2021 (January 1-June 30, 2021)

(2) Reason for the revisions
In the consolidated first quarter, shipments in Kuraray’s businesses mainly in the Vinyl acetate and Isoprene segments increased due to growth in demand, including for mainstay applications for automobiles, displays, and electronic and electric devices. We assume that demand will remain firm in the second quarter as well. Furthermore, in the first quarter, we recorded a loss on litigation of ¥3,054 million related to a fire that occurred at our U.S. subsidiary in May 2018. As stated above, we also recorded a disaster loss of ¥3,016 million due mainly to the suspension of production for some equipment at our U.S. subsidiary caused by a severe cold wave in the southern United States in February. Based on these circumstances, the forecast of consolidated operating results for the second quarter of fiscal 2021 (January 1, 2021 to June 30, 2021) is as shown above.

"We reported another great quarter largely based on all-time record high quarterly FC2 net revenues from the U.S. prescription channel," said Mitchell Steiner, M.D., Chairman, President and Chief Executive Officer of Veru Inc. "We also will be enrolling our first patient in our Phase 3 clinical trial of sabizabulin in high risk hospitalized COVID-19 patients this week. Because of sabizabulin’s anti-inflammatory and anti-viral properties and its favorable safety profile, we think sabizabulin could be that desperately needed oral therapeutic to prevent deaths in hospitalized patients with moderate to severe COVID-19 disease who are at risk for Acute Respiratory Distress Syndrome (ARDS). COVID-19 remains a serious threat worldwide and effective treatments are desperately needed."

Dr. Steiner noted: "We are advancing our novel oral drug candidates for the treatment of prostate and breast advanced cancers. We plan this month to enroll our first patient in the Phase 3 VERACITY clinical trial of sabizabulin for metastatic castration and androgen receptor targeting agent resistant prostate cancer. We plan to also enroll this month our first patient in the Phase 2 clinical trial of VERU-100, a novel long-acting GnRH antagonist injection formulation for androgen deprivation therapy. Next month, the Phase 3 ARTEST enobosarm for 3rd line AR+ER+ metastatic breast cancer is also expected to start enrolling. We are now a solid late clinical stage oncology biopharmaceutical company with novel drug candidates in development."

Pharmaceutical Pipeline Highlights:

Sabizabulin (VERU-111) a Novel Oral Agent for the Treatment of Hospitalized COVID-19 Patients at High Risk for Acute Respiratory Distress Syndrome (ARDS)- Phase 3 Clinical Study.

We expect to enroll our first patient within a few days in our Phase 3 clinical trial of sabizabulin, a novel once a day orally dosed small molecule that has both broad anti-viral and anti-inflammatory activities which may serve a two-pronged approach to the treatment of COVID-19 virus infection and the subsequent debilitating inflammatory effects that lead to ARDS and death, in high risk hospitalized COVID-19 patients. The Phase 3 clinical trial is a double-blind, multicenter, multinational, randomized (2:1), placebo-controlled trial evaluating daily oral doses of 9 mg sabizabulin for up to 21 days versus placebo in 300 hospitalized patients (200 subjects will be treated with sabizabulin and 100 subjects will receive placebo/standard of care) who tested positive for the SARS-CoV-2 virus and who are at high risk for ARDS. Because of better oral bioavailability, the systemic blood levels from the 9 mg sabizabulin dosage are similar to the 18 mg sabizabulin formulation used in the Phase 2 clinical study. Subjects in the sabizabulin and placebo arms will also be allowed to receive standard of care. The primary efficacy endpoint will be proportion of patients that die on study up to Day 60. Secondary endpoints will include the proportion of patients without respiratory failure, days in ICU, WHO Ordinal Scale for Clinical Improvement change from baseline, days on mechanical ventilations, days in the hospital, and viral load. The study will be conducted in the United States, Brazil, Argentina, Mexico, and Colombia. Enrollment is targeted to be completed by calendar year-end.

In February of this year, the Company announced positive clinical results from the Phase 2 trial evaluating sabizabulin for the treatment of hospitalized patients with COVID-19 who were at high risk for ARDS. We conducted a double-blind, randomized, placebo-controlled Phase 2 clinical trial evaluating daily oral once a day dosing of sabizabulin 18 mg versus placebo in approximately 40 hospitalized COVID-19 patients who were at high risk for ARDS. This trial was conducted in 5 sites across the United States. Patients that were hospitalized with documented evidence of COVID-19 infection with symptoms and who were at high risk for ARDS were enrolled. Subjects received either sabizabulin 18 mg or placebo as well as standard of care for 21 days or until released from hospital. The primary efficacy endpoint was the proportion of patients that were alive without respiratory failure at Day 29. For the primary endpoint in the modified intent to treat population, sabizabulin compared to placebo had a statistically significant and clinically meaningful 81% relative reduction in death or respiratory failure at Day 29. With respect to secondary endpoints, sabizabulin had a statistically significant 82% relative reduction in patient mortality and statistically significant reduction in days in ICU; there was also a decrease in days on mechanical ventilation versus placebo. Sabizabulin was well tolerated with a good safety profile.

Sabizabulin a Novel, Oral, Androgen Receptor Transport Disruptor for the Treatment of Metastatic Castration and Androgen Receptor Targeting Agent Resistant Prostate Cancer – Phase 3 VERACITY Clinical Study.

Sabizabulin is a novel, oral, new chemical entity that targets microtubules in the cytoskeleton to disrupt androgen receptor transport. We anticipate enrolling patients this month into the open label, randomized (2:1), multicenter Phase 3 VERACITY clinical trial of sabizabulin 32 mg versus an alternative androgen receptor targeting agent for the treatment of chemotherapy naïve men with metastatic castration resistant prostate cancer who have failed at least one androgen receptor targeting agent. Based on the recently conducted Phase 2 PK study, the blood levels of the Phase 3 clinical trial sabizabulin 32 mg drug dose formulation are similar to the Phase 1b/2 VERU-111 63 mg dosage formulation. The primary endpoint is median radiographic progression free survival. The Phase 3 VERACITY clinical trial is expected to enroll approximately 245 patients.

In the Phase 1b /Phase 2 clinical trial in metastatic castration and androgen receptor targeting agent resistant prostate cancer, chronic daily administration of sabizabulin was well tolerated with a good safety profile. There was also evidence of efficacy including PSA declines and objective and durable tumor responses (partial and complete responses).

VERU-100, a Novel, Proprietary Long-Acting Gonadotropin-Releasing Hormone (GnRH) Antagonist Peptide, 3-Month Subcutaneous Depot Formulation, for Androgen Deprivation Therapy of Advanced Prostate Cancer – Phase 2 Clinical Study.

We anticipate initiation of the Phase 2 clinical trial of VERU-100 androgen deprivation therapy for hormone sensitive advanced prostate cancer this month. The Phase 2 VERU-100 clinical trial is expected to enroll approximately 35 patients. VERU-100 formulation is designed to address the current limitations of commercially available ADT. Androgen deprivation therapy is currently the mainstay of advanced prostate cancer treatment and is used as a foundation of treatment throughout the course of the disease even as other endocrine, chemotherapy, or radiation treatments are added or stopped. Specifically, VERU-100 is a chronic, long-acting GnRH antagonist peptide administered as a small volume, three-month depot subcutaneous injection without a loading dose. VERU-100 immediately suppresses testosterone with no testosterone surge upon initial or repeated administration, a problem that occurs with currently approved luteinizing hormone-releasing hormone (LHRH) agonists used for ADT. There are no GnRH antagonist depot injectable formulations commercially approved beyond a one-month injection. A Phase 3 registration clinical trial in approximately 100 men is anticipated to begin in the second half of calendar year 2021.

Enobosarm a Novel Oral Selective Androgen Receptor Targeted Agonist, for the Treatment of Androgen Receptor Positive (AR+), Estrogen Receptor Positive (ER+) and Human Epidermal Growth Factor Receptor 2 Negative (HER2-) Metastatic Breast Cancer – Phase 3 ARTEST Clinical Study and Phase 2 Enobosarm Combination Study.

We expect to commence our pivotal enobosarm Phase 3 ARTEST clinical study in the second quarter of calendar year 2021. Enobosarm is the first new class of targeting endocrine therapy in advanced breast cancer in decades. Enobosarm is an oral, new chemical entity, selective androgen receptor agonist that targets and activates the androgen receptor (AR), a tumor suppressor, in AR+ER+HER2- metastatic breast cancer without the unwanted masculinizing side effects. Enobosarm has extensive nonclinical and clinical experience having been evaluated in 25 separate clinical studies in approximately 1,450 treated subjects, including three Phase 2 clinical studies in advanced breast cancer involving more than 250 patients. In the two Phase 2 clinical studies conducted in women with AR+ER+HER2- metastatic breast cancer, enobosarm demonstrated significant antitumor efficacy in heavily pretreated cohorts that failed estrogen receptor targeting agents, chemotherapy, and/or CDK 4/6 inhibitors and was well tolerated with a favorable safety profile. In the fourth quarter of calendar 2020, the FDA agreed to the Phase 3 multicenter, international, open label, and randomized (1:1) ARTEST registration clinical trial design to evaluate the efficacy and safety of enobosarm monotherapy versus physician’s choice of either exemestane or a SERM as an active comparator for the treatment of metastatic AR+ER+HER2- breast cancer in approximately 210 patients who have failed a nonsteroidal aromatase inhibitor, fulvestrant and a CDK4/6 inhibitor (3rd line treatment in a metastatic setting) The primary endpoint is median radiographic progression-free survival. In a separate clinical development program, enobosarm in combination with abemaciclib, CDK4/6 inhibitor, will be evaluated in a 2nd line metastatic setting in AR+ER+ metastatic breast cancer. A Phase 2 study to evaluate the efficacy and safety of enobosarm in combination with CDK 4/6 inhibitor (abemaciclib) compared to estrogen receptor blocking agent (Active Control ) for the treatment of AR+ER+HER2- metastatic breast cancer in patients that have failed an estrogen receptor blocking agent plus a CDK 4/6 inhibitor (palbociclib) is expected to commence in calendar Q3 2021.

Sabizabulin a Novel, Oral, Cytoskeleton Disruptor Agent for the Treatment of Systemic Chemotherapy including Taxane Resistant Metastatic Triple Negative Breast Cancer – Phase 2b Clinical Study.

Sabizabulin is also being evaluated for the treatment of taxane chemotherapy resistant metastatic triple negative breast cancer in a planned Phase 2b clinical study in approximately 200 women expected to begin in calendar Q3 2021. Metastatic triple negative breast cancer is an aggressive form of breast cancer that occurs in approximately 15% of all breast cancers. This form of breast cancer does not express ER, progesterone receptor (PR), or HER2 and is resistant to endocrine therapies. The first line of treatment usually includes combination chemotherapy which includes IV taxane chemotherapy. Almost all women will eventually develop taxane resistance. Sabizabulin is an oral, first-in-class, new chemical entity that targets and inhibits microtubules to disrupt the cytoskeleton. Sabizabulin is not a substrate for P-glycoprotein drug resistance protein. Over expression of P-glycoprotein is a common mechanism that results in taxane resistance in triple negative breast cancer. Preclinical studies in human triple negative breast cancer grown in animal models demonstrate that sabizabulin significantly inhibits cancer proliferation, migration, metastases, and invasion of triple negative breast cancer cells and tumors that have become resistant to paclitaxel (taxane). Using the safety information from the Phase 1b and Phase 2 sabizabulin prostate cancer clinical studies, the Company plans to meet with the FDA and to commence a three cohort Phase 2b clinical study in calendar Q3 2021 to evaluate oral daily dosing of sabizabulin monotherapy, TRODELVY monotherapy, and sabizabulin + TRODELVY combination therapy in approximately 200 women with metastatic triple negative breast cancer that have become resistant to at least 2 systemic chemotherapies including a taxane.

TADFIN (Tadalafil 5mg and Finasteride 5mg Combination Capsule) for the Treatment of Lower Urinary Tract Symptoms Caused by Benign Prostatic Hyperplasia (BPH) – NDA Filed by FDA; PDUFA Date December 2021.

TADFIN (tadalafil 5mg and finasteride 5mg combination capsule) was developed to treat urinary tract symptoms caused by BPH. Tadalafil (CIALIS) is currently approved for treatment of BPH and erectile dysfunction and finasteride is currently approved for treatment of BPH (finasteride 5mg PROSCAR) and male pattern hair loss (finasteride 1mg PROPECIA). The co-administration of tadalafil and finasteride has been shown to be more effective for the treatment of BPH than finasteride alone with the additional benefit of ameliorating erectile dysfunction. An NDA for TADFIN has been accepted for review by FDA with a PDUFA date in December 2021. If approved, TADFIN is expected to be marketed and distributed by telemedicine and telepharmacy groups.

New Connection Between Gut Microbes And Liver Cancer Uncovered In Mice

On May 12, 2021 Hera BioLabs reported that In a recent study, researchers uncovered a unique mechanism in which gut microbes have the ability to influence the immune response against nearby liver tumors (Press release, Hera BioLabs, MAY 12, 2021, View Source [SID1234579882]). This study was observed in mice, and the results were published December 15, 2020 in Cancer Discovery. This research shows how specific diseases that weaken the protective lining of the gut barrier may aggravate certain liver cancers like cholangiocarcinoma. [1]

Anatomically speaking, the liver sits on top of the stomach which are both connected via a portal vein, meaning that the liver could be potentially susceptible to any of the gut microbes. It’s also been found that multiple other diseases that affect the gut, such as primary sclerosing cholangitis (PSC) and colitis, are associated with an increased risk for cholangiocarcinoma as well.

Many similar studies over the years have found evidence to support that gut microbes do in fact influence the immune system in many ways, including the ability to suppress tumor growth. A lot of recent research has been exploring the influence that these gut microbes have on liver tumors in general.

Researching The Effect Of Myeloid Cells
The research team conducted multiple experiments showing that immune-suppressing cells, called myeloid cells, can accumulate on the liver with a leaky gut barrier in mouse models. Myeloid cells are usually found near tumors, and are also known for immune-suppression activities, so they’re thought to facilitate tumor growth. The results supported this assumption, showing that mice with gut diseases had increased levels of myeloid cells in the liver, and subsequent tumor growth.

The next part of this study is how all of this would translate in patients, which is always the most important question. To start answering this question, the research team observed patients who had PSC or colitis, and they found a similar immune signaling signature that was also found in the mouse models. Similar to the mice with gut disease and liver cancer, these patients had even greater tumor growth and even worse outcomes. Even though these results are very early findings and more research is needed, there is a good potential for therapeutic applications in the near future.

How Using An SRG Rat Platform Can Optimize These Studies
Mouse models have always been a staple with this type of research, but we would suggest Hera’s SRG rat for a more robust and flexible option and for expanding these studies further. Hera’s SRG rats have many anatomical features that would lend well to exploring these connections between PSC and colitis and tumor growth in greater detail. Our humanized rat models have a huge amount of potential in this type of research, as they can not only provide a more accurate representation of safety and efficacy, but also a means for more robust studies very early upstream. With the help from Hera’s platform, better in vivo systems can make studies like the one above more effective and efficient.

"Viracta has emerged from our first quarter as a publicly traded company well-positioned to make a significant impact on patients and create meaningful value for our shareholders. We are on track to initiate our pivotal NAVAL-1 trial as planned this quarter for the treatment of EBV-associated lymphoma, and we look forward to expanding into our second global clinical program in EBV-associated solid tumors in the second half of 2021," said Ivor Royston, M.D., President and Chief Executive Officer of Viracta.

Dr. Royston continued, "Today, we are excited to provide additional details of the NAVAL-1 trial design, which has been reviewed by the United States Food and Drug Administration. We believe the innovative and adaptive design of this registration-enabling pivotal trial will allow us to simultaneously progress towards potential NDA filings in multiple lymphoma subtypes."

First Quarter 2021 and Recent Highlights

Clinical

Announced design of NAVAL-1, a global pivotal trial in Epstein-Barr virus (EBV)-positive relapsed/refractory (R/R) lymphoma. NAVAL-1 (Nanatinostat in Combination with Valganciclovir) is a multinational, multicenter, open-label Phase 2 basket trial. The trial, which will include multiple subtype-specific cohorts of R/R EBV-positive lymphoma patients, is designed to evaluate the anti-tumor activity of the combination treatment of nanatinostat with valganciclovir and is anticipated to enroll up to 140 patients. The primary endpoint of the trial is objective tumor response rate as assessed by an independent review committee. If successful, Viracta believes this trial could support multiple NDA filings across various EBV-positive lymphoma subtypes. Viracta remains on track to initiate NAVAL-1 in Q2 2021.
Completed enrollment in Phase 2 expansion cohort of its Phase 1b/2 R/R EBV-positive lymphoma trial, with updated data expected in H2 2021. VT3996-201, Viracta’s Phase 1b/2 open-label, dose escalation/expansion trial of nanatinostat-valganciclovir combination treatment in R/R EBV-positive lymphoma has generated promising efficacy and safety data to date, as presented at the 62nd American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in December 2020, including preliminary objective response and complete response rates (ORR/CR) of 80%/40% (n=10) and 67%/33% (n=6) in T/NK cell non-Hodgkin’s lymphoma and diffuse large B-cell lymphoma, respectively. The median duration of response was 10.4 months.
Corporate

Closed merger with Sunesis Pharmaceuticals, Inc. Shares of the combined company, Viracta Therapeutics, Inc., commenced trading on the Nasdaq Global Select Market under the ticker symbol "VIRX" on February 25, 2021.
Completed a $65 million private placement. On February 24, 2021, Viracta closed a private financing featuring a premier investor syndicate of biotechnology-focused and institutional accredited investors.
Strengthened balance sheet through a multi-license milestone and royalty monetization transaction with XOMA. In March 2021, Viracta announced that XOMA had purchased the potential future milestones and royalties associated with existing licenses relating to two clinical-stage drug candidates that Viracta obtained in the merger in exchange for an upfront payment of $13.5 million and up to $20 million in a pre-commercialization, event-based milestone. In the merger, Viracta also obtained exclusive and global rights to assets previously held by Sunesis including SNS-510, a PDK-1 inhibitor, and vecabrutinib, a BTK inhibitor. Viracta is evaluating future development and collaboration opportunities for SNS-510 and potential partnering opportunities for vecabrutinib.
Extended intellectual property protection around lead lymphoma program. In March 2021, the U.S. Patent and Trademark Office (USPTO) granted patent 10,953,011, which covers the anticipated dose regimen to be advanced in the NAVAL-1 trial. The patent provides Viracta with intellectual property protection into at least 2040.
Strengthened company leadership with new appointments to the Board of Directors and management team. Throughout the first quarter, Viracta appointed the following life sciences industry veterans to the Board of Directors: Stephen Rubino, Ph.D., MBA, and Barry J. Simon, M.D., who were each appointed following the closing of the merger, Thomas Darcy, who was appointed in connection with the closing of the merger, and Nicole Onetto, M.D., who remained on the combined company’s Board of Directors following the merger. The Company also appointed Cheryl A. Madsen, RAC as Senior Vice President, Regulatory Affairs.

Updated data from Phase 1b/2 trial in R/R EBV-positive lymphoma (VT3996-201): H2 2021
First Quarter 2021 Financial Results

Cash Position – Cash and cash equivalents totaled approximately $129.2 million as of March 31, 2021. Viracta expects to end 2021 with greater than $100 million in cash and cash equivalents, which it expects will be sufficient to fund its operations into 2024.
Research and Development Expenses – Research and development expenses were $4.0 million for the quarter ending March 31, 2021, compared to $3.4 million for the same period in 2020. This increase was primarily due to costs incurred to support study initiation activities for NAVAL–1, in addition to an increase in headcount and non-cash share-based compensation.
General and Administrative Expenses – General and administrative expenses were $3.8 million for the quarter ending March 31, 2021, compared to $1.0 million for the same period in 2020. This increase was primarily due to non-recurring, merger-related costs of approximately $2.0 million incurred in the period, in addition to incremental costs associated with being a publicly traded company and non-cash share-based compensation.
Acquired in-process research and development – Non-recurring, non-cash operating expenses of $84.5 million associated with the write-off of in-process research and development acquired in the merger were recorded for the quarter ending March 31, 2021.
Gain on Royalty Purchase Agreement – Gain on Royalty Purchase Agreement for the quarter ended March 31, 2021 was associated with upfront proceeds of $13.5 million received in connection with the multi-license milestone and royalty monetization transaction with XOMA Corporation in March 2021.
Adjusted income or loss from operations – Adjusted income from operations for the quarter ended March 31, 2021, excluding the non-recurring and non-cash operating expenses associated with the write-off of in-process research and development acquired in the merger (a non-GAAP measure) was $5.6 million, compared to an unadjusted loss from operations of $78.8 million. There is not a comparative adjustment to loss from operations for the same period in 2020.
Net loss – Net loss was $79.2 million, or $5.22 per share (basic and diluted) for quarter ended March 31, 2021, compared to $4.4 million, or $1.86 per share (basic and diluted), for the same period in 2020.

About NAVAL-1

NAVAL-1 (Nanatinostat in Combination with Valganciclovir) is a registration-enabling multinational, multicenter, open-label Phase 2 basket trial. The trial will include multiple subtype-specific with various EBV-positive relapsed/refractory lymphoma and is anticipated to enroll up to 140 patients. The primary endpoint of the trial is objective tumor response rate, while secondary endpoints include duration of response, survival outcomes, and the safety profile of the combined treatment. Trial eligibility includes patients with EBV-positive R/R lymphoma following two or more prior systemic therapies with no available standard therapies. For ENKTL patients only, eligibility includes patients with R/R disease following one or more prior systemic therapies with no available standard therapies who have failed an asparaginase-containing regimen.
