example 1

[0111] Example 1: HDM201 dosing regimen modeling

[0112] platelet model

[0113] Based on the population PK / PD data from clinical study CHDM201X2101, an AML patient platelet model was developed that recognizes that the disease affects the regulation of platelet production. The figure below illustrates the described model.

[0114]

[0115] Myeloid Blast Model

[0116] A bone marrow blast PKPD model was developed that recognizes a delayed effect, loss of effect over time that is recapitulated by the resistance component, and recognizes the impact of intensive administration to reduce resistance. The figure below illustrates the described model.

[0117]

[0118] Derivation of key metrics from simulated platelet and blast curves

[0119] The population PK / PD models of Example 1 and Example 2 were used to simulate time-dependent variation and inter-individual variation in PK, platelet and blast profiles.

[0216] Example 2: In vivo pharmacology of HDM201 and venetoclax combination

[0217] In multiple AML patient-derived orthotopic models, HDM201 was shown to enhance the in vivo antitumor activity of the selective Bcl-2 inhibitor venetoclax. In mutant IDH1 / FLT3-ITD bearing mice, HDM201 treatment alone exhibited minimal anticancer activity (92% T / C, p>0.05). In contrast, HDM201 in combination with venetoclax induced complete tumor regression (-100% Reg), whereas only partial tumor regression was observed with venetoclax alone (-9% to -52% Reg). See Figures 8 and 9.

[0218] Consistent with observations in peripheral blood, by spleen weight and IDH1 R132H IHC staining of positive leukemic cells also observed depletion of leukemic cells in the spleen. HDM201 as a single agent resulted in modest reductions in spleen size and leukemic density. In contrast, HDM201 in combination with venetoclax resulted in almost complete depletion of le...

[0221] Rationale and Design of Dose / Regimen and Duration of Treatment of HDM201 in Combination with Venetoclax

[0222] This is a Phase 1b, multi-arm, open-label study of HDM201 in combination with venetoclax in subjects with AML or high-risk MDS.

[0223] For all subjects, TP53WT status must be characterized by at least the absence of mutations in exons 5, 6, 7, and 8.

[0224] Subjects will receive HDM201 in combination with venetoclax.

[0225] The venetoclax dose will be gradually increased (rising) over a period of 4 to 5 days to reach the target daily dose to be tested (400 or 600 mg), as shown in the diagram below:

[0226] Rise of venetoclax (RU) during cycle 1 (treatment arm 2: HDM201 + venetoclax)

[0227]

[0228] Once subjects have received the planned target daily dose, they will continue with that dose of venetoclax.

[0229] HDM201 doses can be escalated (see Table 3-1 for interim dose levels to be tested). Based...

Description

technical field [0001] The present invention relates to HDM2-p53 interaction inhibitor drug (S)-5-(5-chloro-1-methyl-2-oxo-1,2-dihydro-pyridin-3-yl)-6-(4 -Chloro-phenyl)-2-(2,4-dimethoxy-pyrimidin-5-yl)-1-isopropyl-5,6-dihydro-1H-pyrrolo[3,4-d] Imidazol-4-one [HDM201] and the BCL2 inhibitor 4-(4-{[2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-en-1-yl]methyl} Piperazin-1-yl)-N-[(3-nitro-4-{[(oxan-4 base)methyl]amino}phenyl)sulfonyl]-2-[(1H-pyrrolo[2 , Combinations of 3-b]pyridin-5-yl)oxy]benzamide [venetoclax]. The invention further relates to the use of said combination in the treatment of cancer, especially hematological tumors. The invention further relates to dosages and administration regimens for this combination cancer therapy. Background technique [0002] HDM201 [0003] p53 is induced and activated by a number of potentially tumorigenic processes including aberrant growth signals, DNA damage, ultraviolet light, and protein kinase inhibitors (Millard M et al.
