About Rubraca (rucaparib)

Rubraca is an oral, small molecule inhibitor of PARP1, PARP2 and PARP3 being developed multiple tumor types, including ovarian and prostate cancers, as monotherapy and in combination with other anti-cancer agents. Exploratory studies in other tumor types are also underway. Clovis holds worldwide rights for Rubraca.

Rubraca U.S. FDA Approved mCRPC Indication

Rubraca is indicated for the treatment of adult patients with a deleterious BRCA mutation (germline and/or somatic)-associated metastatic castration-resistant prostate cancer (mCRPC) who have been treated with androgen receptor-directed therapy and a taxane-based chemotherapy. Select patients for therapy based on an FDA-approved companion diagnostic for Rubraca.

This indication is approved under accelerated approval based on objective response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.

Select Important Safety Information

Myelodysplastic Syndrome (MDS)/Acute Myeloid Leukemia (AML) has occurred in patients treated with Rubraca, and are potentially fatal adverse reactions. In 1146 treated patients, MDS/AML occurred in 20 patients (1.7%), including those in long term follow-up. Of these, 8 occurred during treatment or during the 28 day safety follow-up (0.7%). The duration of Rubraca treatment prior to the diagnosis of MDS/AML ranged from 1 month to approximately 53 months. The cases were typical of secondary MDS/cancer therapy-related AML; in all cases, patients had received previous platinum-containing regimens and/or other DNA damaging agents. In TRITON2, MDS/AML was not observed in patients with mCRPC (n=209) regardless of homologous recombination deficiency (HRD) mutation.

Do not start Rubraca until patients have recovered from hematological toxicity caused by previous chemotherapy (≤ Grade 1). Monitor complete blood counts for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities (> 4 weeks), interrupt Rubraca or reduce dose and monitor blood counts weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks or if MDS/AML is suspected, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Rubraca.

Based on findings in genetic toxicity and animal reproduction studies, advise male patients with female partners of reproductive potential or who are pregnant to use effective methods of contraception during treatment and for 3 months following last dose of Rubraca. Advise male patients not to donate sperm during therapy and for 3 months following the last dose of Rubraca.

Most common adverse reactions in TRITON2 (≥ 20%; Grade 1-4) were fatigue/asthenia (62%), nausea (52%), anemia (43%), AST/ALT elevation (33%), decreased appetite (28%), rash (27%), constipation (27%), thrombocytopenia (25%), vomiting (22%), and diarrhea (20%).

Co-administration of rucaparib can increase the systemic exposure of CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates, which may increase the risk of toxicities of these drugs. Adjust dosage of CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates, if clinically indicated. If co-administration with warfarin (a CYP2C9 substrate) cannot be avoided, consider increasing frequency of international normalized ratio (INR) monitoring.

Corporate Developments

On November 30, 2020, TYME announced that Richie Cunningham, former Icagen CEO and Boehringer Ingelheim executive was appointed as TYME’s Chief Executive Officer. The Company also announced that Steve Hoffman remains in the role of Chairman of the board of directors and continues as the Company’s Chief Science Officer, after his successful tenure as Chief Executive Officer since 2015.

Summary of Recent Developments

TYME Presented Data From TYME-88-Panc Study at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2021 Gastrointestinal Cancers Symposium

On January 17, 2021, TYME presented preliminary supporting data from the TYME-88-Panc pivotal study, at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Virtual 2021 Gastrointestinal Cancers Symposium. The new data demonstrate the potential role of SM-88 (racemetyrosine) in advanced pancreatic cancer through the analysis of circulating tumor cells (CTCs) and passively acquired biometrics data from a wearable device. TYME is presently enrolling patients in a multicenter randomized controlled pivotal trial evaluating SM-88 in patients with third-line pancreatic cancer. Learn more at View Source

CTCs correlate with poor prognosis at baseline and throughout treatment may be a clinically relevant biomarker for patients with metastatic pancreatic cancer. These results demonstrated that CTC collection and enumeration were feasible for correlation with traditional trial outcomes. Furthermore, passively acquired biometrics from a wearable device can be collected for correlation with other clinically meaningful outcomes. Also, given that the longest lesion diameter was correlated with CTCs at baseline, additional radiologic feature analysis may prove to validate the importance of CTCs as a predictive biomarker for patients with pancreatic ductal adenocarcinoma.

As of September 15, 2020, the study reported that SM-88 was well tolerated with no treatment-related Grade 4 or 5 adverse advents (AEs). There was one Grade 3 AE that was deemed possibly related to SM-88. The poster presentation is available on our website at (www.tymeinc.com/data-publications).

The select data from the TYME-88-Panc trial are from an investigational study. SM-88 is not approved for the treatment of patients with any disease condition. Patients and physicians can access www.TYMETRIALS.com for more information about ongoing SM-88 clinical trials.

TYME Granted U.S. Patent Claims Covering Use of TYME-19 to Treat COVID-19 Infections

On February 3, 2021, TYME announced that it received notification that the United States Patent and Trademark Office had granted additional patent claims related to the Company’s metabolomic technology platform. U.S. Patent No. 10,905,698 is directed to methods for treating COVID-19 with TYME-19. This patent expands TYME’s patent portfolio to nearly 200 global granted and/or pending patents, broadly covering compositions, methods, manufacturing and use of the Company’s pipeline to 2032, and beyond.

TYME-19 is an investigational compound that is not approved in the U.S. for any disease indication. TYME intends to initiate the appropriate clinical trials to substantiate the safety and efficacy of TYME-19.

About SM-88

SM-88 is an oral investigational modified proprietary tyrosine derivative that is believed to interrupt the metabolic processes of cancer cells by breaking down the cells’ key defenses and leading to cell death through oxidative stress and exposure to the body’s natural immune system. Clinical trial data have shown that SM-88 has demonstrated encouraging tumor responses across 15 different cancers, including pancreatic, lung, breast, prostate and sarcoma cancers with minimal serious grade 3 or higher adverse events. SM-88 is an investigational therapy that is not approved for any indication in any disease. Learn more.

About TYME-18

TYME-18 is a CMBT compound under development that is delivered intratumorally. TYME-18 leverages a member of the bile acid family to create a potential treatment for inoperable tumors. Preliminary observations of the local administration of TYME-18, a combination of a proprietary surfactant system and natural sulfonic acid, suggested its potential as an important regulator of energy metabolism that may impede the ability of tumors to increase in size, which, in addition to its lytic functionality, could prove useful in difficult-to-treat cancers. In initial preclinical xenograft mouse studies, TYME-18 was able to completely resolve over 90 percent (11/12 mice) of established colorectal tumors within 12 days versus an average of over 600 percent growth in the control animals. Learn more.

About TYME-19

TYME-19 is an oral synthetic member of the bile acid family that the Company also uses in its anticancer compound, TYME-18. Because of its expertise in metabolic therapies, the Company was able to identify TYME-19 as a potent, well characterized antiviral bile acid and has performed preclinical experiments establishing effectiveness against COVID-19. Bile acids have primarily been used for liver disease; however, like all steroids, they are messenger molecules that modulate a number of diverse critical cellular regulators. Bile acids modulate lipid and glucose metabolism and can remediate dysregulated protein folding, with potentially therapeutic effects on cardiovascular, neurologic, immune, and other metabolic systems. Some agents in this class also have antiviral properties. In preclinical testing, TYME-19 repeatedly prevented COVID-19 viral replication without attributable cytotoxicity to the treated cells. Previous preclinical research has also shown select bile acids like TYME-19 have had broad antiviral activity.

About TYME-88-Panc Pivotal Trial

The TYME-88-Panc pivotal trial applies the latest advances in the field of cancer metabolism by evaluating the efficacy and safety of an oral investigational compound that targets the metabolic mechanisms of the disease at its source. A prospective, open label pivotal trial in metastatic pancreatic cancer for patients who have failed two lines of any prior systemic therapy. The trial is designed to evaluate the safety and efficacy of SM-88 used with MPS (methoxsalen, phenytoin and sirolimus) in advanced pancreatic cancer and will measure multiple endpoints, including overall survival, progression free survival, relevant biomarkers, quality of life, safety, and overall response rate.

MYLUNG Study Launches, Aiming to Advance Use of Precision Medicine for Metastatic Non-Small Cell Lung Cancer Patients

On February 4, 2021 McKesson, a global leader in healthcare committed to transforming cancer research,reported that it has joined together with life sciences companies, oncology providers and patient advocacy groups in a unique collaborative effort, titled MYLUNG, to advance precision medicine options for non-small cell lung cancer (NSCLC) patients who are being treated in the community (Press release, McKesson, FEB 4, 2021, View Source [SID1234574634]). NSCLC is the most common type of lung cancer according to the American Cancer Society, accounting for about 84% of lung cancer cases.

The MYLUNG consortium – or "Molecularly Informed Lung Cancer Treatment in a Community Cancer Network: A Pragmatic Consortium" – will observe up to 12,000 community-based, metastatic NSCLC patients over a five-year period in one of the first broad, collaborative, research endeavors in lung cancer. In particular, MYLUNG aims to deepen understanding of molecular testing barriers to improve care for lung cancer patients, including those with mutations who may benefit from receiving precision medicine, the practice of leveraging targeted therapies across the continuum of care, as well as expand the opportunity for patients to participate in clinical trials.

"Many patients are not receiving the molecular testing they need to initiate targeted therapy early in their cancer care journey due to long timeframes, lack of coverage or another factor. This testing is critical to determine the patient’s cancer at a molecular level, so oncologists can create a more targeted and precise treatment plan," said Robert L. Coleman, MD, FACOG, FACS, chief scientific officer, US Oncology Research. "In order to fulfill the promise of precision medicine for NSCLC patients, we need a fuller understanding of the barriers, challenges, risks and opportunities around molecularly guided therapies. MYLUNG will draw insights from these datasets that can lead to better therapy for patients in a timelier manner."

Lung cancer treatment is becoming increasingly personalized to include targeted therapies into earlier stages of disease. To support this, MYLUNG provides the framework to conduct research studies that will help define best practices for providers, as well as provide insights for life sciences companies seeking to quickly deliver potentially life-saving treatments to the patients who need them.

The MYLUNG consortium brings together several McKesson-supported organizations focused on transforming and enhancing the cancer care experience including The US Oncology Network, US Oncology Research, and OntadaTM – McKesson’s new oncology technology and insights business – along with life sciences companies and patient advocacy groups. MYLUNG life sciences members currently include Amgen, Eli Lilly and Company and Mirati Therapeutics. Healthcare provider members include Illinois Cancer Specialists, Maryland Oncology Hematology, Minnesota Oncology, New York Oncology Hematology, Oncology Hematology Care, Rocky Mountain Cancer Centers, Southern Cancer Center, Virginia Cancer Specialists, Virginia Oncology Associates and Willamette Valley Cancer Institute and Research Center. Additional collaborators are expected to join throughout the next few months.

"McKesson has always served at the center of care delivery, which has provided a unique perspective on the complexities of cancer care and the growing needs among providers and life sciences companies," said Kirk Kaminsky, president, McKesson U.S. Pharmaceutical. "MYLUNG highlights our ability to integrate a continuous virtual cycle with feedback loops between the US Oncology Research and Ontada research teams and The US Oncology Network sites of care to quickly integrate best practices across The Network, while adaptively responding to the constantly changing landscape of oncology discovery for both diagnostics and treatment."

MYLUNG will consist of three protocols over a five-year period:

Protocol 1 retrospectively reviews real-world data from Ontada’s iKnowMedSM electronic health records (EHRs) of about 3,500 patients treated by providers in The US Oncology Network to understand baseline data on molecular testing across practices and identify historical barriers to testing and precision medicine in community practice.
Protocol 2, enrolling about 1,000 patients from approximately 10 practices, will monitor the real-world patient journey from presentation through their first line of cancer therapy, focusing on how diagnostic biomarker information is obtained, utilized and operationalized in decision-making. Patients are currently being enrolled into Protocol 2.
Protocol 3 will serve as a platform upon which prospectively assessed interventional strategies in patient-engagement algorithms will be conducted. Up to 7,500 patients from approximately 20 participating practices will be recruited over a five-year period. The individual clinical trials will integrate findings from the previous protocols and explore new processes and associated outcomes to help providers make the best treatment recommendations based on the data available and improve access to testing and appropriate therapies for NSCLC patients.
The real-world research model is uniquely suited to take lung cancer care to the next level by providing a window into the actual provider and patient experience. "We created Ontada to help providers, patients and life sciences companies navigate a cancer care world that is growing more complex every day as new precision medicines come to market," said Derek Rago, interim president, Ontada. "MYLUNG will gather real-world data with Ontada’s technology solutions and develop novel insights through its real-world analytics capabilities so that all stakeholders can make informed decisions that are actionable at the point-of-need."

MYLUNG is poised to support meaningful progress and innovation in care delivery and potentially touch and improve thousands of lives. Makenzi Evangelist, MD, physician lead for the pragmatic study and oncologist with New York Oncology Hematology (NYOH), a practice in The Network, said, "During the study and after, we hope that the interventions and our understanding of NSCLC improve, and we see increased testing and appropriate use of targeted therapies – all of which we hope will improve cancer care and patient outcomes."

Castle Biosciences Presents New Data on the Validity and Accuracy of DecisionDx-Melanoma in Patients With T1 Cutaneous Melanoma Tumors at the 19th Annual South Beach Symposium

On February 4, 2021 Castle Biosciences, Inc. (Nasdaq: CSTL), a skin cancer diagnostics company providing personalized genomic information to improve cancer treatment decisions, reported virtual posters on its three skin cancer gene expression profile tests at the 19th Annual South Beach Symposium, taking place from Feb. 4 – 7, 2021 (Press release, Castle Biosciences, FEB 4, 2021, View Source [SID1234574633]).

DecisionDx-Melanoma:

DecisionDx-Melanoma is Castle’s gene expression profile test that uses an individual patient’s tumor biology to predict individual risk of cutaneous melanoma metastasis or recurrence, as well as sentinel lymph node (SLN) positivity, independent of traditional staging factors.

Castle Biosciences is highlighting data on DecisionDx-Melanoma with two posters. The first highlights new data and is entitled, "31-Gene expression profiling improves risk stratification in patients with T1 cutaneous melanoma."

Study methods and findings:

Nearly 70% of melanomas are diagnosed with tumor thickness that is less than or equal to 1.0 mm (T1 tumors), and recurrence-free survival (RFS) is generally good among these patients. However, up to 15% of patients with T1 tumors may experience a recurrence. Moreover, due to the large number of patients with T1 tumors, 27-30% of melanoma-related deaths occur in patients originally diagnosed with a T1 tumor, suggesting better identification of T1 patients at high risk of recurrence or metastasis is needed.
DecisionDx-Melanoma is designed to classify a patient’s recurrence risk as low (Class 1: Class 1A lowest) or high (Class 2: Class 2B highest) and has been validated in multiple prospective and retrospective studies.
Univariate analysis of the study data shows DecisionDx-Melanoma to be a stronger predictor of RFS than SLN status.
Multivariable analysis shows DecisionDx-Melanoma to be a strong, independent predictor of RFS.
With Class 2B RFS status similar to SLN positive status, Class 2B patients warrant follow-up strategies similar to SLN positive patients.
The second DecisionDx-Melanoma poster is entitled, "The clinical and financial impact of the 31-gene expression profile testing on sentinel lymph node biopsy patients selection in patients with T1b cutaneous melanoma."

Study methods and findings:

DecisionDx-Melanoma identifies patients with T1 tumors who have less than a 5% risk of SLN positivity and who have good survival outcomes. These outcomes suggest that such patients could forego the sentinel lymph node biopsy (SLNB) surgical procedure.
The authors analyzed all clinical DecisionDx-Melanoma tests that were reported from Jan. 3, 2019 through Sept. 4, 2020. The data showed that 75% of eligible patients with T1b tumors had a Class 1A result and could potentially forego SLNB. The authors estimate that foregoing SLNB in these patients could reduce healthcare expenditures by up to $120 million in SLNB-related costs.
DecisionDx DiffDx-Melanoma:

DecisionDx DiffDx-Melanoma is designed to aid dermatopathologists in characterizing difficult-to-diagnose melanocytic lesions.

The virtual poster is entitled, "Development, Validation, and Clinical Utility of the 35-Gene Expression Profile Test for Use as an Adjunctive Melanoma Diagnostic Tool."

Study methods and findings:

DecisionDx DiffDx-Melanoma has demonstrated accuracy metrics of: 99.1% sensitivity, 94.3% specificity, 93.6% positive predictive value and 99.2% negative predictive value; the test also provides a modest intermediate-risk zone of 3.6% and a technical success rate of 96.6%.
Dermatopathologists who used DecisionDx DiffDx-Melanoma to refine their diagnoses in lesions reported increased diagnostic confidence by 51%. Dermatologists used the test result to gauge prognosis, case difficulty, office visit frequency and re-excisions, which were influenced by DecisionDx DiffDx-Melanoma’s result in the appropriate manner in most responses.
The diagnosis of challenging melanocytic lesions and subsequent clinical management decisions were determined to be influenced by the test in agreement with its result, potentially alleviating uncertainty in difficult-to-diagnose lesions. Therefore, DecisionDx DiffDx-Melanoma could lead to a potential increase in accurate diagnoses and focused reduction of burdensome and unnecessary procedures for cases that receive a benign DecisionDx DiffDx-Melanoma result.
DecisionDx-SCC:

DecisionDx-SCC is Castle’s prognostic gene expression profile test for patients diagnosed with high-risk cutaneous squamous cell carcinoma (SCC) designed to use a patient’s tumor biology to predict individual risk of metastasis for patients with SCC and one or more risk factors.

The virtual poster is entitled, "Clinical utility of the 40-gene expression profile (40-GEP) for improved patient management decisions and disease related outcomes when combined with current clinicopathological risk factors for cutaneous squamous cell carcinoma (cSCC): Case Series."

"National guidelines for high-risk SCC patients leave room for subjectivity in assessing which patients warrant additional management," said study author and assistant professor of clinical dermatology at the Indiana University School of Medicine, Ally-Khan Somani, M.D., Ph.D. "Meanwhile, the incidence of SCC is rising with time, which increases the need for physicians to assess metastatic risk objectively for these patients, so that we can provide care accordingly. We have found that DecisionDx-SCC, by predicting tumor aggressiveness based on its gene expression, may stratify risk when integrated with commonly used staging factors to better inform SCC management decisions."

Study methods and findings:

Two SCC cases were presented that highlight DecisionDx-SCC’s utility in stratifying risk in SCC.
The cases were very similar at diagnosis, both presenting with a history of immunosuppression along with identical staging (T2a per Brigham and Women’s Hospital staging; T1 per American Joint Committee on Cancer staging), but had divergent outcomes:
Case 1 did not recur, despite incomplete resection.
Case 2 developed local recurrence and regional metastasis, and died from SCC, despite clear surgical margins, radiation and chemotherapy treatments.
Subsequent DecisionDx-SCC test results yielded risk level assignments that correlated with the two patients’ outcomes:
Case 1 had a retrospective low-risk (Class 1) DecisionDx-SCC result.
Case 2 had a highest-risk (Class 2B) DecisionDx-SCC result.
The authors concluded that incorporating DecisionDx-SCC as a prognostic factor with traditional clinicopathological risk factors can improve stratification of high-risk SCC patients with at least one risk factor, thereby informing risk-appropriate management strategies.
About DecisionDx-Melanoma

DecisionDx-Melanoma is a gene expression profile test that uses an individual patient’s tumor biology to predict individual risk of cutaneous melanoma metastasis or recurrence, as well as sentinel lymph node positivity, independent of traditional staging factors, and has been studied in more than 5,700 patient samples. Using tissue from the primary melanoma, the test measures the expression of 31 genes. The test has been validated in four archival risk of recurrence studies of 901 patients and six prospective risk of recurrence studies including more than 1,600 patients. Prediction of the likelihood of sentinel lymph node positivity has also been validated in two prospective multicenter studies that included more than 3,000 patients. Impact on patient management plans for one of every two patients tested has been demonstrated in four multicenter and single-center studies including more than 560 patients. The consistent performance and accuracy demonstrated in these studies provides confidence in disease management plans that incorporate DecisionDx-Melanoma test results. Through September 30, 2020, DecisionDx-Melanoma has been ordered more than 64,560 times for use in patients with cutaneous melanoma.

More information about the test and disease can be found at www.CastleTestInfo.com.

About DecisionDx DiffDx-Melanoma

DecisionDx DiffDx-Melanoma is designed to aid dermatopathologists in characterizing difficult-to-diagnose melanocytic lesions. Of the approximately 2 million suspicious pigmented lesions biopsied annually in the U.S., Castle estimates that approximately 300,000 of those cannot be confidently classified as either benign or malignant through traditional histopathology methods. DecisionDx DiffDx-Melanoma classifies these lesions as: benign (gene expression profile suggestive of benign neoplasm); intermediate-risk (gene expression profile cannot exclude malignancy); or malignant (gene expression profile suggestive of melanoma). Interpreted in the context of other clinical, laboratory and histopathologic information, DecisionDx DiffDx-Melanoma is designed to add diagnostic clarity and confidence for dermatopathologists while helping dermatologists deliver more informed patient management plans.

About DecisionDx-SCC

DecisionDx-SCC is a 40-gene expression profile test that uses an individual patient’s tumor biology to predict individual risk of cutaneous squamous cell carcinoma metastasis for patients with one or more risk factors. The test result, in which patients are stratified into a Class 1, 2A or 2B risk category, predicts individual metastatic risk to inform risk-appropriate management.

Peer-reviewed publications have demonstrated that DecisionDx-SCC is an independent predictor of metastatic risk and that integrating DecisionDx-SCC with current prognostic methods can add positive predictive value to clinician decisions regarding staging and management.
