Helsinn one step closer to bringing anamorelin HCI to market for treatment of anorexia, cachexia in NSCLC patients

Helsinn, the Swiss pharmaceutical Group focused on building quality cancer care, today announced that the European Medicines Agency (EMA) accepted for review, the marketing authorization application (MAA) for anamorelin HCI, a novel, orally active selective ghrelin receptor agonist under development for the treatment of anorexia, cachexia, or unintended weight loss in non-small cell lung cancer (NSCLC) patients.

Riccardo Braglia, Chief Executive Officer of Helsinn Group commented, "With this EMA submission, we are one step closer to bringing this new and potentially effective treatment to market, meaning that the quality of life for patients with non-small cell lung cancer who suffer from anorexia, cachexia, could soon improve. Anamorelin is part of our pipeline of products dedicated to cancer supportive care, all of which address areas of significant unmet medical need."

Toxicity limits benefits of bevacizumab–erlotinib NSCLC maintenance therapy

In continuation of my update on bevacizumab and erlotinib 

Two targeted anticancer drugs used together after first-line chemotherapy for advanced stage non-small-cell lung cancer (NSCLC) improve progression-free survival (PFS), the results of a large, prospective study show.

Median PFS was 4.8 months for patients treated with bevacizumab plus erlotinib versus 3.7 months for those treated with bevacizumab plus placebo (hazard ratio [HR] = 0.71). There was no overall survival (OS) advantage, however, and the two-drug combination was associated with more adverse events than bevacizumab alone, say the study investigators.

FDA Approves Gilotrif for Late Stage Non-Small Cell Lung Cancer

We know that, Afatinib, trade name Gilotrif, previously Tomtovok and Tovok is an approved drug against non-small cell lung carcinoma (NSCLC), developed by Boehringer Ingelheim. As of  2012, it is undergoing Phase III clinical trials for this indication and breast cancer, as well as Phase II trials for prostate and head and neck cancer, and a Phase I glioma trial. Afatinib is a first-line treatment.

Now FDA has approved...

“Today’s approvals further illustrate how a greater understanding of the underlying molecular pathways of a disease can lead to the development of targeted treatments,” said Richard Pazdur, M.D., director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “Gilotrif is the second drug approved this year for patients with untreated metastatic NSCLC whose tumors have the EGFR exon 19 deletions or exon 21 L858R substitution mutations.”

In May, the FDA approved Tarceva (erlotinib) for first-line treatment of patients with NSCLC. Tarceva’s new indication was approved concurrently with the cobas EGFR Mutation Test, a companion diagnostic to identify patients with tumors having the EGFR gene mutations.

“The approval of companion diagnostic tests and drugs are important developments in oncology, as they help us bring safe and effective treatments to patients who need them,” said Alberto Gutierrez, Ph.D., director of the Office of In Vitro Diagnostics and Radiological Health in the FDA’s Center for Devices and Radiological Health...

Synta announces results from ganetespib Phase 2b trial on NSCLC

In continuation of my update on Ganetespib....

"The preliminary results from GALAXY indicate that the addition of ganetespib to docetaxel is well tolerated and may improve outcomes in patients compared to docetaxel alone," said Dr. Ramalingam, a Principal Investigator of the study. "This includes promising improvements in survival seen across the broad adenocarcinoma population as well as in key predefined patient populations. A well-tolerated combination regimen that extends survival associated with salvage therapy in NSCLC will meet a much awaited need to improve the current standard of care."

As per the CEO's statement "the objective of the interim analysis was to identify the best choice of patient population and trial design for transitioning to the Phase 3 stage of the study. The broad-based activity seen in the results presented  support advancing into the Phase 3 stage in alladenocarcinoma patients. The results have yielded a rich data set which we are using to optimize and de-risk the Phase 3 stage of the program. We are hopeful that this next stage of development will lead to a new treatment option for patients fighting this devastating disease."

Enrollment completion of the Phase 2b stage of the GALAXY trial and the transition to the Phase 3 stage are expected later this year. Based on current assumptions, the Company anticipates that Phase 3 will enroll approximately 500 adenocarcinoma patients, with overall survival as a primary endpoint. Biomarker findings and other patient selection and treatment experience from the Phase 2b stage will be incorporated into the design of the Phase 3 stage. An announcement with additional Phase 3 details is anticipated later this year, following discussion with regulatory agencies.

Metformin could serve as radiosensitizer to treat patients with stage III non-small cell lung cancer

In continuation of my update on metformin

Treating aggressive lung cancer with the diabetes drug metformin along with radiation and chemotherapy may slow tumor growth and recurrence, suggests new preliminary findings from researchers at the Perelman School of Medicine at the University of Pennsylvania being presented during an oral abstract session October 28 at the 15th World Conference on Lung Cancer.

The pre clinical and clinical results, which have set the stage for a first-of-its-kind prospective study, point to metformin as an effective radiosensitizer-a drug that makes tumor cells more sensitive to radiation therapy-to treat stage III non-small cell lung cancer (NSCLC). Because of poor local response and five-year survival rates around 15 percent in late-stage NSCLC patients, well-tolerated, combination therapies are greatly needed.

The abstract is being presented by Ildiko Csiki, MD, PhD, an assistant professor of Radiation Oncology at Penn's Abramson Cancer Center.

Metformin, the most-widely used drug for type-2 diabetes, has been shown to have anti-cancer effects on a number of cancers, including prostate and colon. It activates AMP-related pathways, leading to inactivation of mTOR and suppression of its downstream effectors, a crucial signaling pathway for proliferation and survival of cancer. However, little data exists to support its role in NSCLC. And its role as a radiosensitizer in lung cancer is even less understood.

New targeted therapy shows promise in patients with ALK-positive advanced NSCLC

An international study involving Manchester researchers has found that for previously untreated lung cancer patients with a particular genetic change, a new targeted therapy is better than standard chemotherapy.

Some patients with non-small cell lung cancer (NSCLC) have changes in the anaplastic lymphoma kinase (ALK) gene, which can drive the development of their cancer. A drug recently developed by Pfizer, crizotinib (see structure), targets ALK and is currently given to patients with ALK positive lung cancer when their cancer has worsened after initial chemotherapy. Now doctors have investigated the use of crizotinib in patients with ALK positive lung cancer who have not yet received any chemotherapy treatment.

Xalkori Approved For Rare Genetic Form of Lung Cancer

In continuation of my update on Xalkori (crizotinib)

Xalkori (crizotinib) has been approved by the U.S. Food and Drug Administration to treat advanced non-small cell lung cancer (NSCLC) with tumors that have a rare ROS-1 gene mutation.The drug was approved in 2011 to treat advanced NSCLC that was related to an abnormal ALK gene, the agency said Friday in a news release.

Lung cancer is the leading cause of cancer death in the United States. Last year, more than 221,000 cases were diagnosed and more than 158,000 people died from it, the FDA said.

Clinical studies of 50 people with ROS-1-positive NSCLC found that about two-thirds of participants treated with Xalkori had their tumors partially or completely shrink for an average of 18 months, the agency said.

The drug's most common side effects include nausea, diarrhea, vomiting, swelling, constipation, elevated liver enzymes, fatigue, loss of appetite and upper respiratory infection. More serious adverse reactions could include liver problems, lung inflammation, abnormal heartbeat and loss of vision.

LUME-Lung 1 shows QoL, symptoms benefits

LUME-Lung 1 (Nintedanib + docetaxel) trial patients’ reports of symptoms and health-related quality of life (HRQoL) support the use of second-line nintedanib for the treatment of advanced non-small-cell lung cancer (NSCLC).

Initial findings from the phase III trial demonstrated that the angiokinase inhibitor plus docetaxel offered significantly better progression-free survival for patients with advanced NSCLC, including subpopulations with adenocarcinoma, than placebo plus docetaxel, explain Silvia Novello (University of Turin, Italy) and co-authors in theEuropean Journal of Cancer.

For the current study, the team used a battery of tests to compare patient-reported outcomes on day 1 of each 21-day treatment cycle, at the end of treatment and at the first follow-up visit for the two treatment groups.

Over 80% of the 655 nintedanib-treated patients and 659 of controls completed the European Organisation for Research and Treatment of Cancer Core QoL Questionnaire and its lung cancer supplement, with 70% doing so at the end of treatment.

Baseline health and QoL were comparable for the nintedanib and placebo groups with relatively good scores and a low burden of lung cancer-specific symptoms, such as cough and pain.

The patient groups also had comparable time to deterioration for cough, pain and dyspnoea, although patients given nintedanib had a significantly shorter time to development of the gastrointestinal symptoms of nausea, vomiting, diarrhoea and decreased appetite.

Similarly, the 322 patients with adenocarcinoma histology given nintedanib alongside docetaxel had a similar time to deterioration of lung cancer symptoms as the 336 given placebo, with a small benefit in global health and QoL with nintedanib detected but this did not reach significance.

Cisplatin doubles lung cancer survival time in mice !

When I was studying my M.Sc., (1992), we used to have a question regarding the anticancer activity of cisplatin and after that I could see lots of research in the field of anticancer activity. And so many new drugs have been established and are being used as drugs. Cisplatin works by crosslinking across DNA inter-strands, making it impossible for rapidly dividing cells to duplicate their DNA for cell division (mitosis). The damaged DNA sets off DNA repair mechanisms which fails to work, so in turn activate cell death processes (apoptosis). The trans isomer does not have this pharmacological effect.

After so many years, I could find this something interesting findings about cisplatin, by Patrizia Russo of Lung Cancer Unit of the National Cancer Research Institute in Genoa, Italy and colleagues from San Raffaele Pisana Scientific Institute for Research, Hospitalization and Health Care (IRCCS), Catholic University.

In the study, the authors took the research a step further and showed that α-CbT could inhibit non-small cell lung carcinoma (NSCLC) growth and prolong life in non-obese/severe combined immunodeficient (NOD/SCID) mice that had human NSCLC grafted to their lungs. This study attempted to mimic human cancer conditions more closely by delaying treatment until the tumors were well-established. In addition to control mice that were untreated, the researchers randomized one third of the mice to receive standard chemotherapy.

They found that NOD/SCID mice treated with the standard chemotherapy agent, cisplatin, had a 16 percent longer median survival time than untreated mice (p= 0.05). Mice treated with α-CbT, however, had an increased median survival time of 1.7-fold over the cisplatin-treated mice and 2.1-fold over the no-treatment controls (p=0.0005). Though the clinical trials to establish the claim and to to explore the widest range of possibilities of intervention on the α7-nAChRs. Congrats...

Drug Combo Tackling Solid Tumors

Cancer Research UK's Drug Development Office has opened the first trial of a new drug combination in patients with advanced solid tumors and in a subset of patients who have non-small cell lung cancer. This trial will combine two compounds that aim to starve the tumors while simultaneously blocking cancer cell growth.

The study will take place across three UK hospitals. The Churchill Hospital, Oxford is the lead center. The trial of up to 48 patients will run in two stages. In the first stage patients with any solid tumor will each receive a drug called vandetanib (below left) and an investigational drug called selumetinib (right structure below)AZD6244, ARRY142886). In the second stage patients with non-small cell lung cancer (NSCLC) will receive the combination.

This is the first time the compounds have been trialled together. It is hoped that combining these treatments will increase the number of cancer ‘weakspots’ targeted at the same time.

Chief investigator, Dr. Denis Talbot, consultant medical oncologist at Oxford University Hospitals NHS Trust and Cancer Research UK clinician at The University of Oxford, said: “Therapies for lung cancer often become ineffective because the disease becomes resistant to treatment, so we’re delighted to launch this trial to test a new approach that we hope will help people with this common disease.

“There is progress being made in the treatment of lung cancer but survival rates still remain low. This is because the majority of patients – up to two thirds – are diagnosed once the cancer has already spread to other organs when it’s more difficult to treat successfully.

 “We hope that this new approach may eventually contribute to increased survival for lung cancer patients.”

Afatinib a better choice for EGFR-mutated lung cancer in first-line treatment

In continuation of my update on Afatinib

Patients with EGFR-activating mutations in advanced lung cancer seem to benefit more from afatinib than gefitinib as first-line treatment, researchers report at the first ESMO Asia 2015 Congress in Singapore.

In the global, randomised, open-label Phase IIb LUX-Lung 7 (LL7) trial1, the irreversible ErbB family blocker afatinib significantly improved efficacy versus gefitinib across a range of clinically relevant endpoints, such as progression-free survival, time-to-treatment failure and objective response rate. "Based on these results I would consider afatinib as the EGFR tyrosine kinase inhibitor (TKI) of choice for the first-line treatment for patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC)," lead author, Professor Keunchil Park, head of the Division of Hematology/Oncology at Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea, said.

NSCLC is the most common type of lung cancer: activating epidermal growth factor receptor (EGFR) gene mutations are more frequently observed in non-smokers and women, and occur in 50% of Asians and only 10% of non-Asians. The targeted agents afatinib and gefitinib block key pathways involved in tumour growth and spread. They have both been approved for the treatment of naive patients, based on the results of Phase III trials, confirming their superiority compared to chemotherapy. Unlike the first-generation EGFR inhibitor gefitinib, the irreversible ErbB family blocker afatinib is suggested to be active in prolonging tumour response and delaying disease progression.

Early trial results in lung cancer

Results from early phase trials investigating different therapeutic agents in lung cancer patients were presented during the third Presidential Session at the European Cancer Congress in Vienna, Austria. Here we summarise two studies reported at the session.

Erlotinib (structure) plus bevacizumab promising in EGFR T790M-positive advanced NSCLC patients. 

Rolf Stahel, from University Hospital Zurich in Switzerland, presented the findings of the BELIEF trial [1] on behalf of his fellow investigators from the Spanish Lung Cancer Group and the European Thoracic Oncology Platform. The phase II trial enrolled 109 patients with metastatic or locally advanced non-squamous non-small-cell lung cancer (NSCLC) harbouring activating epidermal growth factor receptor (EGFR) mutations (either the exon 19 deletion or the exon 21 L858R point mutation).

Of these, 37 (33.9%) patients also carried the EGFR T790M mutation at baseline, while the remaining 72 participants were negative for T790M.

Patients were treated with a combination of everolimus and bevacizumab on the basis of previous preclinical results suggesting that inhibiting both the EGFR and vascular EGFR pathways could be beneficial in the presence of the T790M mutation, explained Stahel.

After a median follow-up of 17.5 months, progression-free survival (PFS) was a median of 13.8 months in the overall cohort, with times of 16.0 and 10.5 months for the T790M-positive and -negative groups, respectively. The corresponding 1-year PFS rates were 56.7%, 72.4% and 49.4%.

Complete responses were achieved by 6.4% of all study participants, 8.1% of those positive for T790M and 5.6% of T790M-negative patients, while partial responses were achieved by 69.7%, 62.2% and 73.6% of patients, respectively.

Early trial results in lung cancer

PARP inhibitor, MK-4827, shows anti-tumour activity in first trial in humans....

MK-4827 , (S)-2-(4-(piperidin-3-yl)phenyl)-2H-indazole-7-carboxamide hydrochloride.

A recent study claim that the new drug MK-4827 (see structure), that targets proteins responsible for helping cancer cells to repair damage to their DNA has shown promising anti-tumor activity in its first trial in humans. Some patients with a range of solid tumors, many of whom had been treated unsuccessfully for their cancer with other therapies, have seen their tumors shrink or stabilize for periods of between 46 days to more than a year.

Laboratory studies of the drug, MK-4827, have shown that it inhibits proteins called PARP1 and PARP2  (poly(ADP)-ribose polymerase). PARP is involved in a number of cellular processes and one of its important functions is to assist in the repair of single-strand breaks in DNA. As per the claim by the researchers, drug act by inhibiting the action of PARP, double-strand breaks occur, leading to cell death. Researchers add that tumors that are caused by a mutation in the BRCA1 or BRCA2 genes are susceptible to cell death through PARP inhibition because correctly functioning BRCA genes assist in repairing double-strand DNA breaks via a process called homologous-recombination-dependent DNA repair, whereas mutated versions are unable to perform this role. Normal cells don't replicate as often as cancer cells and they still have homologous repair operating; this enables them to survive the inhibition of PARP and makes PARP a good target for anti-cancer therapy.

In a Phase I trial conducted at the H Lee Moffitt Cancer Center (Tampa Florida, USA), University of Wisconsin-Madison (Madison, USA) and the Royal Marsden Hospital (London, UK), MK-4827 was given to 59 patients (46 women, 13 men) with a range of solid tumors such as non-small cell lung cancer (NSCLC), prostate cancer, sarcoma, melanoma and breast and ovarian cancers. Some patients had cancers caused by mutations in the BRCA1/2 genes, such as breast and ovarian cancer, but others had cancers that had arisen sporadically.

The researchers saw anti-tumor responses in both sporadic and BRCA1/2 mutation-associated cancers. Ten patients with breast and ovarian cancers had partial responses, with progression-free survival between 51-445 days, and seven of these patients are still responding to treatment. Four patients (two with ovarian cancer and two with NSCLC) had stable disease for between 130-353 days.

Breakthrough in ovarian cancer: Selumetinib

In continuation  of my update on Seumetinab

We know that, Selumetinib (AZD6244) is a drug being investigated for the treatment of various types of cancer, for example non-small cell lung cancer (NSCLC). 

Mode of action : The gene BRAF is part of the MAPK/ERK pathway, a chain of proteins in cells that communicates input from growth factors. Activating mutations in the BRAF gene, primarily V600E (meaning that the amino acid valine in position 600 is replaced by glutamic acid), are associated with lower survival rates in patients with papillary thyroid cancer. Another type of mutation that leads to undue activation of this pathway occurs in the gene KRAS and is found in NSCLC. A possibility of reducing the activity of the MAPK/ERK pathway is to block the enzyme MAPK kinase (MEK), immediately downstream of BRAF, with the drug selumetinib. More specifically, selumetinib blocks the subtypes MEK1 and MEK2 of this enzyme....

The study was initially developed in 2007, with 52 patients enrolled for the Phase II clinical trial between December 2007 and November 2009. Patients were given 50 milligrams of selumetinib orally twice daily. Of those participants, eight had a measurable decrease in tumor size, seven had partial responses and 34 patients saw their tumors stabilize. The findings suggest that inhibitors of the MAPK pathway warrant further investigation in patients with low-grade ovarian cancer.

"There just aren't very good treatments for low-grade ovarian cancer, so this discovery opens up a lot of new exciting possibilities for us," Dr. Farley said. He added that Phase III of this trial is scheduled to begin in the next few weeks, with that trial to be the "definitive test" before the treatment becomes available to the general population.

Brigatinib drug shows promise against ALK non-small cell lung cancer in phase I/II clinical trial

Phase I/II clinical trial results reported at the American Society for Clinical Oncology (ASCO) Annual Meeting 2015 show promising results for investigational drug brigatinib against ALK+ non-small cell lung cancer (NSCLC), with 58 of 78 ALK+ patients responding to treatment, including 50 of 70 patients who had progressed after previous treatment with crizotinib, the first licensed ALK inhibitor. Progression-free survival (PFS) in patients previously treated with crizotinib was 13.4 months.

"Although still only in an early phase trial, brigatinib is showing an objective response rate in approximately 70 percent of ALK-positive patients post-crizotinib and it's showing about a year of progression-free survival. These results are among the best in the field, offering a lot of hope to people with ALK-positive lung cancer," says D. Ross Camidge, MD, PhD, director of thoracic oncology at the University of Colorado Cancer Center and the trial's principal investigator.

In addition, robust data is emerging on drug activity in patients with brain involvement of the disease. Many lung cancer trials have traditionally excluded patients with brain metastases at baseline, expecting that the presence of metastases would create negative results that could in turn create the appearance of drug failure. Following early recognition of the importance of the brain as a potential differentiator between the activity of new drugs, the brigatinib trial includes patients with untreated brain metastases, showing a greater than 30 percent decrease in size of brain tumors in 8 of 15 patients with brain tumors greater than 10 mm and disappearance of brain metastases in 11 of 33 patients with smaller lesions only. Brain metastases remained controlled for a median 15.6 months.

Based on these promising early results, brigatinib, developed by Ariad Pharmaceuticals, Inc., recently received Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) for the treatment of patients with ALK+ metastatic NSCLC whose tumors are resistant to crizotinib (below structure)

New Drug Application of Plinabulin (Response Letter from the FDA) for Prevention of Chemotherapy-Induced Neutropenia (CIN)...

 BeyondSpring Pharmaceuticals  announced the receipt of  a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) for the New Drug Application (NDA) seeking approval of plinabulin in combination with granulocyte colony-stimulating factor (G-CSF) for the prevention of chemotherapy-induced neutropenia (CIN). The FDA issued the CRL to indicate that they have completed their review of the application and have determined that it cannot be approved in its present form.

 

The FDA’s CRL indicated that the results of the single registrational trial (106 Phase 3) was not sufficiently robust to demonstrate benefit and that a second well controlled trial would be required to satisfy the substantial evidence requirement to support the CIN indication.

“BeyondSpring strongly believes that plinabulin in combination with G-CSF has significant potential to raise the standard of care in CIN, a devastating side effect of chemotherapy,” said Dr. Lan Huang, BeyondSpring’s co-founder, chief executive officer and chairwoman. “The Company plans to request a meeting with the FDA and remains committed to its goal of bringing plinabulin to cancer patients in need globally.”

BeyondSpring remains confident in the efficacy and safety data for plinabulin in combination with G-CSF for the prevention of CIN. The Company expects to work closely with the FDA to consider the possible future clinical pathway for CIN, which may include a second study.

Plinabulin is the first drug candidate submitted for FDA approval that has the potential to work in the critical first week of chemotherapy treatment before G-CSF is effective, to prevent the onset and improve clinical outcomes of CIN.

Plinabulin, BeyondSpring’s lead asset, is a selective immunomodulating microtubule-binding agent (SIMBA), which is a potent antigen presenting cell (APC) inducer. It is a novel, intravenous infused, patent-protected, NDA-stage asset for CIN prevention and a Phase 3 anti-cancer candidate for non-small cell lung cancer (NSCLC) with recently released positive topline data. Plinabulin triggers the release of the immune defense protein, GEF-H1, which leads to two distinct effects: first is a durable anticancer benefit due to the maturation of dendritic cells resulting in the activation of tumor antigen-specific T-cells to target cancer cells, and the second is early-onset of action in CIN prevention after chemotherapy by boosting the number of hematopoietic stem/progenitor cells (HSPCs). Plinabulin received Breakthrough Therapy designation and priority review from both U.S. and China FDA for the CIN prevention indication. As a “pipeline in a drug,” plinabulin is being broadly studied in combination with various immuno-oncology agents that could boost the effects of the PD-1/PD-L1 antibodies and re-sensitize PD-1/PD-L1 antibody-resistant patients.

Spectrum Pharmaceuticals Submits New Drug Application for Poziotinib

Spectrum Pharmaceuticals, a biopharmaceutical company focused on novel and targeted oncology therapies, announced the submission of  its New Drug Application (NDA) for poziotinib to the U.S. Food and Drug Administration (FDA) for use in patients with previously treated locally advanced or metastatic non-small cell lung cancer (NSCLC) with HER2 exon 20 insertion mutations. The NDA submission is based on the positive results of Cohort 2 from the ZENITH20 clinical trial, which assessed the safety and efficacy of poziotinib. The product has received Fast Track designation and there is currently no treatment specifically approved by the FDA for this indication.

“The NDA submission for poziotinib marks an important step in achieving a first treatment for patients with HER2 exon 20 insertion mutations in lung cancer,” said Joe Turgeon, President and CEO of Spectrum Pharmaceuticals. “I want to thank the patients, investigators and our internal staff who have passionately worked to achieve this important milestone in an area of high unmet medical need.”

ZENITH20 Cohort 2 Clinical Results Summary

Results for Cohort 2 of the ZENITH20 clinical trial have been published in the Journal of Clinical Oncology (November 29, 2021), and can be accessed by clicking here.

Cohort 2 enrolled 90 patients who received an oral once daily dose of 16 mg of poziotinib. The intent-to-treat analysis demonstrated a confirmed objective response rate (ORR) of 27.8% (95% Confidence Interval (CI), 18.9%-38.2%). The observed lower bound of 18.9% exceeded the pre-specified lower bound of 17%. The median duration of response was 5.1 months and the median progression free survival was 5.5 months. In this cohort, 87% of patients had drug interruptions with 11 patients (12%) permanently discontinuing due to adverse events. 13 patients (14%) had treatment-related serious adverse events. As previously announced, the company had a successful pre-NDA meeting with the FDA which resulted in an agreement to submit an NDA for poziotinib. During the meeting, Spectrum confirmed with the FDA that Cohort 2 data could serve as the basis of an NDA submission. The company will continue to work with the FDA as appropriate, while the agency conducts its review.
