Definitions

  • ONC201 (7-benzyl-4-(2-methylbenzyl)-l,2,6,7,8,9-hexahydroimidazo [l,2-a]pyrido [3,4-e]pyrimidin-5(lH)-one) is the founding member of a class of anti-cancer compounds called imipridones that is in Phase II clinical trials in multiple advanced cancers. Since its discovery as a p53-independent inducer of TRAIL gene transcription, preclinical studies have shown that it has anti-proliferative and pro-apoptotic effects against a broad range of tumor cells but not normal cells.
  • ONC201 is orally active with infrequent dosing in animal models, causes sustained pharmacodynamic effects, and is not genotoxic.

  • H3 K27M a specific mutation in histone H3 proteins
  • DIPG diffuse intrinsic pontine glioma
  • Gliomas in the midline of the brain belong to the most aggressive types of primary malignant brain cancers.
  • the disease arises from glial cells, which form the tissue that surrounds and protects other nerve cells found within the brain and spinal cord.
  • Standard therapy for midline gliomas involves neurosurgery, when feasible, followed by fractionated external beam radiotherapy. Due to location in the brain, aggressiveness and low survival time, gliomas in the midline of the brain are considered as part of the most lethal forms of cancer.
  • No medical therapies have been shown to prolong survival in H3 K27M mutant adult and pediatric glioma patients. Standard-of-care DIPG treatment, 55Gy focal radiation fractionated over 6 weeks, is associated with a 9-11 -month overall survival.
  • Adult H3 K27M glioma is often treated with the same regimen as glioblastoma that involves radiation with concomitant and maintenance temozolomide. Despite its use to treat this newly defined disease in adults, this regimen’s efficacy has not been evaluated specifically in adult mutant H3 K27M glioma patients.
  • histones are predominantly protein-DNA and protein-protein interactions; they do not function as enzymes, which represent the bulk of targeted cancer therapy (kinases, HDAC inhibitors, etc.).
  • kinases, HDAC inhibitors, etc. kinases, HDAC inhibitors, etc.
  • no therapies directly target the mutant H3 proteins itself (such as the case for mutant BRAF); instead, therapeutic efforts have focused on targeting features of tumor cells with H3 K27M mutations, such as their epigenetic- and transcription-dependency.
  • Inhibition of proteins involved in epigenetics such as histone deacetylates, histone de-methylases, or bromodomains have yielded efficacy in preclinical models, however their ability to improve clinical outcome has not been shown.
  • H3 K27M glioma therapies A major challenge for effective H3 K27M glioma therapies is the need to penetrate the blood-brain barrier, a rare feature of current cancer therapies. This is further enhanced by the location of these tumors in midline brain structures, which has been shown to be harder to penetrate than other brain locations.
  • the H3 K27M mutation also tends to occur in midline gliomas with dopamine present and DRD2 expression prevalent in the tumor environment.

  • ONC201 is a first-in-class small molecule discovered in a phenotypic screen for p53 -independent inducers of tumor selective proapoptotic pathways. Oral ONC201 is being evaluated as a new therapeutic agent in five early phase clinical trials for select advanced cancers based on pronounced efficacy in aggressive and refractory tumors and excellent safety. [00294] In this Example, the prediction and validation of selective direct molecular interactions between ONC201 and specific dopamine receptor family members are reported. Experimental GPCR profiling indicated that ONC201 selectively antagonizes the D2-like, but not DI -like, dopamine receptor subfamily.
  • ONC201 selectively antagonizes both short and long isoforms of DRD2 and DRD3, with weaker potency for DRD4 and no antagonism of DRD1 or DRD5.
  • Increased secretion of prolactin is a clinical hallmark of DRD2 antagonism by several psychiatric medications that potently target this receptor.

GPCR arrestin recruitment and cAMP modulation reporter assays were performed as described (see McGuinness et al., Journal of Biomolecular Screening 14:49 (2009)). PathHunterTM (DiscoveRx) P-arrestin cells expressing one of several GPCR targets were plated onto 384-well white solid bottom assay plates (Corning 3570) at 5000 cells per well in a 20 pL volume in an appropriate cell plating reagent.
  • ONC201 is a small molecule in phase II clinical trials for select advanced cancers. It was discovered in a phenotypic screen for p53 -independent inducers of the pro-apoptotic TRAIL pathway. Although the contribution of ONC201 -induced ATF4/CHOP upregulation and inactivation of Akt/ERK signaling (Allen et al., Science translational medicine 5, 171ral 17-17 Iral 17 (2013)) to its anti-cancer activity has been characterized, its molecular binding target had remained elusive.
  • ONC201 selectively antagonizes the D2-like (DRD2/3/4), but not Dl-like (DRD1/5), dopamine receptor subfamily (Fig. 1). Antagonism of adrenoceptor alpha receptors or other GPCRs was not observed under the evaluated conditions.
  • ONC201 antagonized both short and long isoforms of DRD2 and DRD3, with weaker potency for DRD4.
  • ONC201 -mediated antagonism of arrestin recruitment to DRD2L was assessed by a Gaddum/Schild EC50 shift analysis, which determined a dissociation constant of 2.9 pM for ONC201 that is equivalent to its effective dose in many human cancer cells. Confirmatory results were obtained for cAMP modulation in response to ONC201, which is another measure of DRD2L activation. The ability of dopamine to reverse the dose-dependent antagonism of up to 100 pM ONC201 suggests direct, competitive antagonism of DRD2L. In agreement with the ONC201 specificity predicted by BANDIT, no significant interactions were identified between ONC201 and nuclear hormone receptors, the kinome, or other drug targets of FDA- approved cancer therapies.
  • ONC201 selectively antagonizes the D2-like dopamine receptor subfamily, which appears to be a promising therapeutic target in oncology, and ONC201 is the first compound to exploit this treatment paradigm in several ongoing Phase II clinical studies.
  • Reference Example 13 Preclinical data in H3 K27M adult and pediatric glioma.
  • H3 K27M refers to a specific mutation in histone H3 proteins. Due to the location of these tumors, areas of the brain involved in critical physiological functions, these tumors have historically been inoperable (especially in the brain stem where the pons is located). This means that until recently, midline gliomas such as diffuse intrinsic pontine glioma (DIPG) were diagnosed solely on a radiographic basis.
  • DIPG diffuse intrinsic pontine glioma
  • Gliomas in the midline of the brain belong to the most aggressive types of primary malignant brain cancers. The disease arises from glial cells, which are cells that form the tissue that surrounds and protects other nerve cells found within the brain and spinal cord.
  • Standard therapy for midline gliomas involves neurosurgery, when feasible, followed by fractionated external beam radiotherapy. Due to location in the brain, aggressiveness and low survival time, gliomas in the midline of the brain are considered as part of the most lethal forms of cancer.
  • H3 K27M predominantly occurs in midline gliomas and in younger patients: ⁇ 75% of thalamic brain tumors, ⁇ 54% of brainstem tumors and 55% of spinal cord tumors; 24% of pediatric gliomas and 8% of adult gliomas.
  • the H3 K27M mutation occurs in a unique spatiotemporal pattern, with midline gliomas involving the pons (i.e. DIPG) tending to occur in pediatric patients ( ⁇ 18 years of age) while midline gliomas involving the thalamus and spinal cord tending to occur in young adult patients.
  • H3 K27M mutation in midline gliomas is generally thought to confer a worse clinical prognosis.
  • This understanding was incorporated into the World Health Organization 2016 classification of central nervous system tumors that now defines diffuse midline gliomas with the H3 K27M mutation as a new distinct disease entity. This disease is defined as grade IV regardless of histopathological features due to the widely recognized dismal prognosis of brain tumors with this mutation.
  • H3 K27M Most of the prognostic literature for H3 K27M is derived from DIPG that exhibits a 70-85% prevalence of this mutation. It is clear than the presence of the H3 K27M mutation in tumors of the pons confers a much shorter overall survival relative to the minority of patients who do not have this mutation. For the smaller number of pediatric patients with gliomas outside of the pons, the literature is consistent that those with the H3 K27M mutation have a poorer prognosis. The field looks to DIPG as the most robust body of clinical experience with H3 K27M gliomas based on high prevalence of the mutation in that disease.
  • DIPG clinical trials have failed to improve outcomes and standard-of-care, a 6-week course of radiation, remains associated with a 9-11-month overall survival.
  • therapeutic clinical trials in DIPG focused on the evaluation of therapies that were proven effective in adult high-grade gliomas.
  • the recent molecular profiling and emerging preclinical models of H3 K27M midline gliomas have shown that these tumors exhibit vastly different biology and therapeutic sensitivity relative to other adult gliomas, such as glioblastoma.
  • H3 K27M-mutant gliomas occur at a lower rate in adults compared to pediatric patients.
  • the literature is relatively congruous with pediatric findings and overall seems to confirm the dismal effect of H3 K27M mutations in brain tumors for adults, especially in brainstem gliomas.
  • Overall survival of adult patients with H3 K27M midline gliomas is approximately 16 months with studies indicating that H3 K27M mutations in brainstem locations are associated with significantly shorter survival times.
  • ONC201 One of the features in the selection process that identified ONC201 as an anticancer agent was its ability to penetrate the blood-brain barrier to address tumors residing in the CNS, unlike many available therapies. Ensuing animal studies revealed that ONC201 rapidly traverses the blood-brain barrier, achieves 5-fold higher concentrations in the brain relative to plasma and induces downstream signaling (TRAIL induction) in the brain.
  • ONC201 has p53-indepenent activity against high grade glioma cell lines including those with resistance to radiotherapy. In addition to cell lines, ONC201 exerts potent anticancer activity in primary high grade glioma samples resistant to temozolomide.
  • ONC201 shrinks temozolomide-resistant high-grade glioma xenografts and prolongs the survival of mice with orthotopic xenografts as a monoagent and in combination with bevacizumab. Compelling monoagent efficacy of ONC201 has also been observed in radio- and chemo-resistant high-grade glioma cell lines and in 3D neurosphere cultures of newly diagnosed and recurrent patient samples.
  • DRD2 is overexpressed in high grade glioma.
  • expression levels of DRD2 correlated with the responsiveness of the cells to ONC201 (Fig. 3).
  • expression of DRD5 a Df-like dopamine receptor that counteracts DRD2 signaling, was significantly inversely correlated with ONC201 potency in the NCI60 and GDSC datasets (P ⁇ .05) (Fig. 3).
  • H3 and components of the PRC2 methyl transferase complex which is inhibited by the K27M mutation, were found to each mark both the DRD2 and DRD5 gene in DIPG and isogenic models. While the precise epigenetic mechanisms regulating the balance of the DRD2:DRD5 expression is an active area of investigation, H3 K27M gliomas was hypothesized to foster a chromatin landscape that leads to high DRD2 expression and suppression of DRD5 expression, which in turn may make these tumor cells more sensitive to ONC201. ONC201 was tested against a panel of patient-derived glioma tumorsphere cultures grown in serum-free neural stem cell media.
  • Patient-derived lines included five histone H3 K27M mutant DIPG (two HISTIH3B and three H3F3A mutant), two H3F3A G34 mutant pediatric glioblastoma (one G34V, one G34R), and 7 H3 wild-type (3 pediatric, 4 adult) glioblastoma cell lines.
  • ONC201 was more potently cytotoxic to histone H3 K27M mutant (median ICso ⁇ 0.6
  • DRD2 and DRD5 expression were analyzed in untreated patient glioma samples.
  • DRD5 expression in all glioma tumors tested were low, however DRD5 expression in histone H3 K27M mutant glioma tumors showed a trend towards lower expression than wild-type glioma. Therefore, DRD2 and DRD5 expression profiles of H3 K27M mutant patient gliomas appear consistent with an expression signature in preclinic al models that predicts ONC201 sensitivity.
  • Cancer stem cells have been shown to express relatively high levels of DRD2 compared to the bulk population, and ONC201 effectively depletes cancer stem cells in numerous malignancies. This effect may contribute to prolongation of survival in patients in a Phase II GBM study of ONC201 despite the fact that many patients received limited drug exposure (1 or 2 doses).
  • NK cells are known to express DRD2 and ONC201 has been reported to increase the pool of circulating and intratumoral NK cells. Even more important is activation of NK cell function documented in vivo as well as in patient samples. This significant immune-stimulatory effect likely contributes to the antitumor activity of the compound and is consistent with the response kinetics, i.e. prolonged and late responses, seen in an ongoing clinical trial.
  • the GBM tumor microenvironment has been described as profoundly immune-suppressed and several modalities that stimulate immune function have been shown to affect GBM tumor cell growth.

She also had multi-focal disease and progressed following first-line surgery, radiation, and temozolomide. She also progressed following subsequent second-line therapy with CCNU. Prior to ONC201 treatment, this subject had three lesions. Her first on-treatment evaluation at 8- weeks following initiation of ONC201 therapy revealed a complete disappearance of malignant lesions (Fig. 15). She also tolerates the therapy well and remains on study after > 10 weeks.

PFS will be assessed by Response Assessment in Neuro-Oncology (RANO)-High Grade Glioma (HGG) and RANO-Low Grade Glioma (LGG) criteria using a blinded independent central review (BICR) process. PFS is defined as the time from randomization to the earlier date of progression or death. OS is defined as the time from randomization to the date of death.
  • Pharmacokinetics Plasma concentrations and PK parameters for ONC201 will be determined. The relationship between concentrations of ONC201 and select efficacy and safety endpoints will be investigated. Safety: Safety will be evaluated through the incidence of treatment-emergent AEs and clinical laboratory results. All AEs will be collected and recorded in the electronic case report form (eCRF) from the time of first dose until 30 days after the last dose of study intervention.

Study intervention should be taken with a glass of water and consumed over as short a time as possible. No food should be consumed within 2 hours before or for 2 hours after each dose.
  • the dose may be increased if the weight gain is associated with a higher dose band and is not expected to decrease (as determined by the investigator; adjusting dose is not recommended if weight change is due to water-retention). Document any change in dose. [00351] If a participant’s body weight decreases to a lower dose band, the dose may remain the same if the participant is tolerating the currently assigned dose. Do not change the dose during a treatment cycle unless it is due to an AE attributed to study intervention.
  • Dose Modifications the table below includes criteria for dose modifications (ie, interruption, dose reduction, or discontinuation) due to AEs and adverse events of special interest (AEOSI). Dose modifications will be made based on AEs that occur any time during a cycle.

Submit this scan to the sponsor’s imaging vendor after the potential participant has started radiotherapy. In the event more than 1 scan is available during this time period, the scan that was obtained closest to the time of initiating radiotherapy will be used for assessment of inclusion and stratification. • Post-radiotherapy/baseline: to be obtained 2 to 6 weeks after completion of radiotherapy (prior to randomization). • On study: The first on-treatment MRI will be collected at C3D1 ( ⁇ 7 days).
  • MRIs will be collected approximately every 8 weeks ( ⁇ 7 days). Upon investigator determination of possible radiographic progression, a confirmatory scan is required 4 to 10 weeks later.
