Description

POLYMORPH OF LORLATINIB

FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION

Lorlatinib is a potent, macrocyclic inhibitor of both wild type and resistance mutant forms of anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1) receptor tyrosine kinase. It is indicated for the treatment of patients with ALK -positive metastatic non-small cell lung cancer (NSCLC). Chemically, lorlatinib is designated as (10f?)-7-amino-12-fluoro-2,10,16- trimethyl-15-oxo- 10, 15, 16, 17-tetrahydro-2iT-4,8-(metheno)pyrazolo[4,3- /?][2,5, 1 l]benzoxadiazacyclotetradecine-3-carbonitrile and it can be represented by the following chemical structure according to Formula (A)

Formula (A).

Lorlatinib and its preparation are disclosed in WO 2013/132376 A1 e.g. in Example 2, where lorlatinib is obtained as a white solid. WO 2014/207606 A1 describes various crystalline forms of lorlatinib including a crystalline hydrate Form 1, a crystalline hydrate containing a non-stoichiometric amount of methanol designated as Form 2 and a crystalline acetic acid solvate containing about 1 molecule of acetic acid per one molecule of lorlatinib designated as Form 3. WO 2019/073347 A1 describes an additional hydrate of lorlatinib designated as Form 24.

WO 2017/021823 A1 discloses an anhydrous non-solvated Form 7 of lorlatinib. The marketed products (e.g. Lobrena® in US, Lorviqua® in EU) contain said Form 7.

Different solid-state forms of an active pharmaceutical ingredient often possess different properties. Differences in physicochemical properties of solid-state forms can play a crucial role for the improvement of pharmaceutical compositions, for example, pharmaceutical formulations with improved dissolution profile and bioavailability or with improved stability or shelf-life can become accessible due to an improved solid-state form of an active pharmaceutical ingredient. Also processing or handling of the active pharmaceutical ingredient during the formulation process may be improved. New solid-state forms of an active pharmaceutical ingredient can thus have desirable processing properties. They can be easier to handle, better suited for storage, and/or allow for better purification, compared to previously known solid forms.

The thermodynamically most stable polymorph of an active pharmaceutical ingredient is often used for the preparation of a drug product, since phase transitions during pharmaceutical standard processes like compaction, milling and granulation can be reduced to the extent possible. However, a huge drawback connected with the thermodynamically most stable form of a drug substance is the fact, that it is the least soluble form, which translates into decreased bioavailability. This is especially critical for low soluble compounds like lorlatinib, which is classified as a BCS class 4 substance with low solubility and low permeability (see Assessment report EMA/CHMP/182840/2019). Therefore, using a metastable polymorph of a drug substance is sometimes desirable on account of its special properties, in particular higher solubility and hence bioavailability. However, it is important to avoid any possible solid form transitions, which may occur for a metastable polymorph during pharmaceutical processing or storage, since this can have a huge impact on the safety and efficacy of a drug product. Therefore, not every metastable polymorph of an active pharmaceutical ingredient can be used for the production of a pharmaceutical composition. Due to the low solubility of lorlatinib Form 7, the formulation of a bioavailable oral drug product requires special pretreatment of the drug substance, in this particular case the increase of the drug surface area e.g. by milling.

Aim of the present invention is therefore to address the above described issue connected with the low solubility of lorlatinib Form 7. In particular, the objective of the present invention is to provide an improved polymorph of lorlatinib, which shows high solubility and dissolution rates as well as good wettability and at the same time is kinetically stable e.g. does not undergo phase transformations during standard pharmaceutical processing and storage.

SUMMARY OF THE INVENTION

The present invention solves the above mentioned problems by providing a metastable polymorph of lorlatinib, which is hereinafter also referred to “Form B”. Form B of the present invention was found to be monotropically related to the known Form 7 of WO 2017/021823 Al, with the latter being the higher melting form. No solid-state transformation from form B to form 7 was observed. The experimentally observed transition temperature at which Form B of the present invention transforms to Form 7 of WO 2017/021823 Al is above the melting point of Form B, thus form 7 recrystallises from the melt of form B, which reflects the high kinetic stability of Form B of the present invention and indicates that the probability of solid form changes during standard pharmaceutical processing and during storage is vanishingly small. On the other hand Form B being the metastable polymorph in a monotropic system possesses by definition the higher solubility in the entire temperature range compared to the thermodynamically stable Form 7. Hence, lorlatinib Form B of the present invention combines the advantageous properties of high physical stability and high solubility and is therefore the preferred solid-state form of lorlatinib for the preparation of a pharmaceutical composition.

Another aspect of the present invention concerns solvates of lorlatinib with dimethylformamide (Form S-DMF) and 1,4-dioxane (Form S-DX), respectively. Having these solvates in hands, for the first time allowed the preparation of lorlatinib Form B of the present invention, which can be produced by desolvation of the solvates of the present invention.

Definitions

In the context of the present invention the following definitions have the indicated meaning, unless explicitly stated otherwise:

As used herein the term “room temperature” refers to a temperature in the range of from 20 to

30 °C.

As used herein, the term “measured at a temperature in the range of from 20 to 30 °C” refers to a measurement under standard conditions. Typically, standard conditions mean a temperature in the range of from 20 to 30 °C, i.e. at room temperature. Standard conditions can mean a temperature of about 22 °C. Typically, standard conditions can additionally mean a measurement under 20-80% RH, preferably 30-70% RH, more preferably 40-60% RH and most preferably 50% RH.

The term “Form 7” as used herein, when talking about a solid-state form of lorlatinib refers to the anhydrous non-solvated crystalline form of lorlatinib, which is disclosed in WO 2017/021823 Al. Form 7 of lorlatinib can be characterized by having a powder X-ray diffractogram comprising reflections at 2-Theta angles of (9.6 ± 0.2)°, (10.1 ± 0.2)°, (14.3 ± 0.2)°, (16.2 ± 0.2)° and (17.3 ± 0.2)°, when measured at a temperature in the range of from 20 to 30 °C with Cu-Kalphai,2 radiation having a wavelength of 0.15419 nm. The term “reflection” with regard to powder X-ray diffraction as used herein, means peaks in an X-ray diffractogram, which are caused at certain diffraction angles (Bragg angles) by constructive interference from X-rays scattered by parallel planes of atoms in solid material, which are distributed in an ordered and repetitive pattern in a long-range positional order. Such a solid material is classified as crystalline material, whereas amorphous material is defined as solid material, which lacks long-range order and only displays short-range order, thus resulting in broad scattering. According to literature, long-range order e.g. extends over approximately 100 to 1000 atoms, whereas short-range order is over a few atoms only (see “Fundamentals of Powder Diffraction and Structural Characterization of Materials ” by Vitalij K. Pecharsky and Peter Y. Zavalij, Kluwer Academic Publishers, 2003, page 3).

The term “essentially the same” with reference to powder X-ray diffraction means that variabilities in reflection positions and relative intensities of the reflections are to be taken into account. For example, a typical precision of the 2-Theta values is in the range of ± 0.2° 2-Theta, preferably in the range of ± 0.1° 2-Theta. Thus, a reflection that usually appears at 8.7° 2-Theta for example can appear between 8.5 and 8.9° 2-Theta, preferably between 8.6 and 8.8° 2-Theta on most X-ray diffractometers under standard conditions. Furthermore, one skilled in the art will appreciate that relative reflection intensities will show inter-apparatus variability as well as variability due to degree of crystallinity, preferred orientation, particle size, sample preparation and other factors known to those skilled in the art and should be taken as qualitative measure only.

The term “essentially the same” with reference to infrared spectrometry means that variabilities in peak positions and relative intensities of the peaks are to be taken into account. For example, a typical precision of the wavenumber values is in the range of ± 4 cm ¹, preferably in the range of ± 2 cm ¹. Thus, a peak at 2233 cm ¹ for example can appear between (2229) and (2237) cm ^x, preferably between (2231) and (2235) cm ¹ on most infrared spectrometers under standard conditions. Peak intensities can be derived from according figures, but one skilled in the art will appreciate that differences in peak intensities due to degree of crystallinity, sample preparation, measurement method and other factors can also occur in infrared spectroscopy. Peak intensities should therefore be taken as qualitative measure only.

The anhydrous and non-solvated crystalline Form B of lorlatinib of the present invention may be referred to herein as being characterized by graphical data "as shown in" a figure. Such data include, for example, powder X-ray diffraction and FTIR spectroscopy. The person skilled in the art understands that factors such as variations in instrument type, response and variations in sample directionality, sample concentration and sample purity may lead to small variations for such data when presented in graphical form, for example variations relating to the exact peak positions and intensities. However, a comparison of the graphical data in the figures herein with the graphical data generated for another or an unknown solid-state form and the confirmation that two sets of graphical data relate to the same crystal form is well within the knowledge of a person skilled in the art.

The terms “solid form” or “solid-state form” as used herein interchangeably refer to any crystalline and/or amorphous phase of a compound.

As used herein, the term “amorphous” refers to a solid form of a compound that is not crystalline. An amorphous compound possesses no long-range order and does not display a definitive X-ray diffraction pattern with reflections.

As used herein the term “polymorph” refers to crystalline forms having the same chemical composition but different spatial arrangements of the molecules, atoms, and/or ions forming the crystal.

The term “hydrate” as used herein, refers to a crystalline solid where either water is cooperated in or accommodated by the crystal structure e.g. is part of the crystal structure or entrapped into the crystal (water inclusions). Thereby, water can be present in a stoichiometric or non- stoichiometric amount. When water is present in stoichiometric amount, the hydrate may be referred to by adding greek numeral prefixes. For example, a hydrate may be referred to as a /lew/hydrate or as a /wiz/ohydrate depending on the water/compound stoichiometry. The water content can be measured, for example, by Karl-Fischer-Coulometry.

The term “solvate” as used herein, refers to a crystalline solid where either one or more organic solvent(s) is/are cooperated in or accommodated by the crystal structure e.g. is/are part of the crystal structure or entrapped into the crystal (solvent inclusions). Thereby, the one or more organic solvent(s) can be present in a stoichiometric or non-stoichiometric amount. When the one or more organic solvent(s) is/are present in stoichiometric amount(s), the solvate may be referred to by adding greek numeral prefixes. For example, a solvate may be referred to as a hemi solvate or as a /ww solvate depending on the solvent(s)/compound stoichiometry. The solvent content can be measured, for example, by GC, NMR, SXRD and/or TGA/MS.

The terms “desolvating” or “desolvation” as used herein, describe the at least partial removal of organic solvent from the crystal structure of the host molecule.

The terms “anhydrous” or “anhydrate” as used herein refer to a crystalline solid where no water is cooperated in or accommodated by the crystal structure. Anhydrous forms may still contain residual water, which is not part of the crystal structure but may be adsorbed on the surface or absorbed in disordered regions of the crystal. Typically, an anhydrous form does not contain more than 2.0 w-%, preferably not more than 1.0 w-%, more preferably not more than 0.5 w- % of water, based on the weight of the crystalline form.

The term “non-solvated” as used herein, when talking about a crystalline solid indicates that no organic solvent is cooperated in or accommodated by the crystal structure. Non-solvated forms may still contain residual organic solvents, which are not part of the crystal structure but may be adsorbed on the surface or absorbed in disordered regions of the crystal. Typically, a non- solvated form does not contain more than 2.0 w-%, preferably not more than 1.0 w-%, more preferably not more than 0.5 w-% of organic solvents, based on the weight of the crystalline form.

As used herein, the term “mother liquor” refers to the solution remaining after crystallization of a solid from said solution.

The term “antisolvent” as used herein refers to liquids which reduce the solubility of lorlatinib in a solvent.

A “predetermined amount” as used herein with regard to lorlatinib refers to the initial amount of lorlatinib used for the preparation of a pharmaceutical composition having a desired dosage strength of lorlatinib.

The term “effective amount” as used herein with regard to lorlatinib encompasses an amount of lorlatinib, which produces the desired therapeutic and/or prophylactic effect.

As used herein, the term “about” means within a statistically meaningful range of a value. Such a range can be within an order of magnitude, typically within 10%, more typically within 5%, even more typically within 1% and most typically within 0.1% of the indicated value or range. Sometimes, such a range can lie within the experimental error, typical of standard methods used for the measurement and/or determination of a given value or range.

The term “pharmaceutically acceptable excipient” as used herein refers to substances, which do not show a significant pharmacological activity at the given dose and that are added to a pharmaceutical composition in addition to the active pharmaceutical ingredient. Excipients may take the function of vehicle, diluent, release agent, disintegrating agent, dissolution modifying agent, absorption enhancer, stabilizer or a manufacturing aid among others. Excipients may include fillers (diluents), binders, disintegrants, lubricants and glidants.

The term “filler” as used herein refers to substances that are used to dilute the active pharmaceutical ingredient prior to delivery. Fillers can also serve as stabilizers.

As used herein the term “binder” refers to substances which bind the active pharmaceutical ingredient and pharmaceutically acceptable excipient together to maintain cohesive and discrete portions.

The terms “disintegrant” or “disintegrating agent” as used herein refer to substances which, upon addition to a solid pharmaceutical composition, facilitate its break-up or disintegration after administration and permit the release of the active pharmaceutical ingredient as efficiently as possible to allow for its rapid dissolution.

The term “lubricant” as used herein refers to substances which are added to a powder blend to prevent the compacted powder mass from sticking to the equipment during tableting or encapsulation process. They aid the ejection of the tablet from the dies and can improve powder flow.

The term “glidant” as used herein refers to substances which are used for tablet and capsule formulations in order to improve flow properties during tablet compression and to produce an anti -caking effect.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a metastable polymorph of lorlatinib, herein also designated as “Form B”. Despite being a metastable polymorph, Form B of lorlatinib of the present invention possesses high physical stability, e.g. it is stable against temperature, moisture and/or mechanical stress (see Example 5 herein). The fact that Form B is monotropically related to the already known Form 7, with Form 7 being the higher melting form, implies that Form B of the present invention shows higher solubility, a fact which translates in higher bioavailability of a low soluble drug like lorlatinib (see Comparative Example 1 and 2 herein). Hence, Form B of the present invention combines the advantageous properties of high physical stability and high solubility and is therefore the ideal solid-state form of lorlatinib for the preparation of an improved pharmaceutical composition e.g. a pharmaceutical composition with increased bioavailability, which is safe and effective during its whole shelf-life.

Crystalline Form B of lorlatinib of the present invention may be characterized by analytical methods well known in the field of the pharmaceutical industry for characterizing solids. Such methods comprise but are not limited to powder X-ray diffraction, FTIR spectroscopy, DSC and TGA. It may be characterized by one of the aforementioned analytical methods or by combining two or more of them. In particular, Form B of lorlatinib of the present invention may be characterized by any one of the following embodiments or by combining two or more of the following embodiments.

In yet another embodiment, the invention relates to an anhydrous and non-solvated crystalline form (Form B) of lorlatinib characterized by having a PXRD comprising reflections at 2-Theta angles of (8.7 ± 0.1)°, (11.2 ± 0.1)°, (11.8 ± 0.1)°, (15.2 ± 0.1)°, (17.2 ± 0.1)°, (18.8 ± 0.1)°, (21.5 ± 0.1)°, (21.9 ± 0.1)° and (23.2 ± 0.1)°, when measured at a temperature in the range of from 20 to 30 °C with Cu-Kalphai,2 radiation having a wavelength of 0.15419 nm.

The PXRD of Form B of the present invention can be readily distinguished from the PXRD of Form 7 of WO 2017/021823 Al .

EXAMPLES The following non-limiting examples are illustrative for the disclosure and are not to be construed as to be in any way limiting for the scope of the invention.

Example 1: Preparation of lorlatinib Form B

Method A:

Lorlatinib Form S-DMF (e.g. prepared according to one of the procedures described in Example 2 herein) was air-dried for 24 hours at RT, then ground using a mortar and pestle. The sample was then air-dried for another 24 hours at RT. The solvate (approximately 200 mg) was then heated from RT to 180 °C using a heating rate of ~10 K/min. Heating was performed using a hot-stage microscope. The resulting solid form was characterised with powder X-ray diffaction and TGA and consisted of Form B. The sample was heated a second time from RT to 180 °C, heating rate ~10 K/min (HSM) and confirmed to still be form B using powder X-ray diffaction.

Method B :

Lorlatinib Form S-DX (e.g. prepared according to one of the procedures described in Example 3 herein) was air-dried for 30 minutes at RT, then ground using a mortar and pestle. The solvate (approximately 150 mg) was then heated from RT to 180 °C using a heating rate of ~10 K/min. Heating was performed using a hot-stage microscope. The resulting solid form was characterised with powder X-ray diffaction and TGA and consisted of Form B. The sample was heated a second time from RT to 180 °C, heating rate ~10 K/min (HSM) and confirmed to still be form B using powder X-ray diffaction.

Example 2: Preparation of lorlatinib DMF solvate (Form S-DMF)

Method A:

Amorphous lorlatinib (250 mg, e.g. prepared according to the procedure described in Example 2 of WO 2013/132376 Al) was placed in a round-bottom flask and dissolved in DMF (2 mL). The solvent was evaporated using a rotary evaporator (40 °C/8-10 mbar) until crystallization of a white solid had occured. The obtained solid was air-dried for 24 hours to obtain lorlatinib Form S-DMF.

Method B:

DMF (0.05 mL) was added to lorlatinib Form 7 (20 mg, e.g. prepared according to the procedure described in Example 1 of WO 2017/021823 Al). The mixture was stirred for one day at ambient conditions. The solid obtained was collected by filtration and air-dried for 24 hours to obtain lorlatinib Form S-DMF.

Method C:

Two drops of DMF were added to amorphous lorlatinib (35 mg e.g. prepared according to the procedure described in Example 2 of WO 2013/132376 Al). The mixture was transferred either into a ball-mill jar and ground for 10 minutes at 30 Hz or transferred into a mortar and ground manually. After air drying both procedures produced lorlatinib Form S-DMF.

Example 3: Preparation of lorlatinib 1,4-dioxane solvate (Form S-DX)

Method A:

Amorphous lorlatinib (50 mg e.g. prepared according to the procedure described in Example 2 of WO 2013/132376 Al) was placed into glass vials. Up to five drops of different mixtures of 1,4-dioxane and «-heptane (v/v): 1:3, 1:2, 1:1, 2:1 and 3:1 were added and the mixtures were stirred for 12 hours at RT.

The mixtures were transferred either into a ball-mill jar and ground for 10 minutes at 30 Hz or transferred into a mortar and ground manually to produce lorlatinib Form S-DX.

Example 4: Characterization of the solid-state forms of the present invention (Form B, Form S-DMF and Form S-DX)

Powder X-ray diffraction PXRDs of Form B, S-DMF and Form S-DX were recorded (at 25 °C) with an X’Pert PRO diffractometer (PANalytical, Almelo, The Netherlands) equipped with a Theta/Theta coupled goniometer in transmission geometry, programmable XYZ stage with well plate holder, Cu- Kai,2 radiation source with a focussing mirror, a 0.5° divergence slit, a 0.02° sober slit collimator and a 1° anti -scattering slit on the incident beam side, a 2 mm anti -scattering slit, a 0.04° sober slit collimator, a Ni-fbter and a solid-state PIXcel detector on the diffracted beam side. The patterns were recorded at a tube voltage of 40 kV, tube current of 40 mA, applying a step-size of 0.013° 2-Theta with 1000 s or 2400 s per step (255 channels) in the angular range of 2° to 40° 2-Theta.

A representative diffractogram of crystalline form B of lorlatinib is displayed in Figure 1 herein. The corresponding reflection list is provided in Table 1 below. Table 1: PXRD reflection positions of crystalline Form B of lorlatinib in the range of from 2 to 30° 2- Theta; a typical precision of the 2-Theta values is in the range of ± 0.2° 2-Theta, preferably of ± 0.1° 2- Theta.

Figure 2 illustrates an overlay of the PXRDs of lorlatinib Form B of the present invention (bottom) and Form 7 of WO 2017/021823 A1 (top). As can be seen both forms can be readily distinguished from each other by powder X-ray diffractometry. For example, the PXRD of lorlatinib Form B possesses refelections at (8.7 ± 0.2)°, (13.3 ± 0.2)°, (16.7 ± 0.2)° and (18.8 ± 0.2)° 2-Theta, whereas no reflections are visible in the PXRD of lorlatinib Form 7 in this range. On the other hand, the PXRD of lorlatinib Form 7 displays i.a. reflections at (9.6 ± 0.2)°, (12.6 ± 0.2)° and (16.2 ± 0.2)° 2-Theta, whereas the PXRD of lorlatinib Form 7 shows no reflection in these ranges.

A representative diffractogram of the crystalline DMF solvate (Form S-DMF) of lorlatinib is displayed in Figure 6 herein. The corresponding reflection list is provided in Table 2 below.

Table 2: PXRD reflection positions of crystalline Form S-DMF of lorlatinib in the range of from 2 to 30° 2-Theta; a typical precision of the 2-Theta values is in the range of ± 0.2° 2-Theta, preferably of ± 0.G 2-Theta.

A representative diffractogram of the crystalline 1,4-dioxane solvate of lorlatinib (Form S-DX) is displayed in Figure 7 herein. The corresponding reflection list is provided in Table 3 below.

Table 3: PXRD reflection positions of crystalline Form S-DX of lorlatinib in the range of from 2 to 30° 2-Theta; a typical precision of the 2-Theta values is in the range of ± 0.2° 2-Theta, preferably of ± 0.1° 2-Theta. Fourier transform infrared spectroscopy

The FTIR spectrum was recorded (obtained) on an MKII Golden Gate™ Single Reflection Diamond ATR cell with a Bruker Tensor 27 FTIR spectrometer with 4 cm ¹ resolution at RT. To record a spectrum a spatula tip of the sample was applied to the surface of the diamond in powder form. Then the sample was pressed onto the diamond with a sapphire anvil and the spectrum was recorded. A spectrum of the clean diamond was used as background spectrum

A representative FTIR spectrum of the crystalline Form B of lorlatinib according to the present invention is displayed in Figure 3 and the corresponding peak list is provided in Table 4 below.

Table 4: FTIR peak list of crystalline Form B of lorlatinib according to the present invention; atypica precision of the wavenumbers is in the range of ± 4 cm ¹, preferably of ± 2 cm ¹. Differential scanning calorimetry DSC was performed on a Mettler Polymer DSC R instrument. The sample (4.46 mg) was heated in a 40 microL aluminium pan with a pierced aluminium lid from 25 to 250 °C at a rate of 10 K/min. Nitrogen (purge rate 50 mL/min) was used as purge gas.

A representative DSC curve (excerpt from 25 to 220 °C) is displayed in Figure 4 hereinafter and shows an endotherm with an onset temperature of about 191 °C and a peak temperature of about 198 °C, which is due to the melting of the sample.

Thermogravimetric analysis

TGA was carried out with a TGA7 system (Perkin-Elmer, Norwalk, Connecticut, USA) using Pyris 2.0 software. Approximately 4 mg of sample was weighed into a platinum pan. Two-point calibration of the temperature was performed with ferromagnetic materials (Alumel and Ni, Curie-point standards, Perkin-Elmer). The sample was heated to 225 °C at a rate of 10 K/min and dry nitrogen was used as a purge gas (sample purge: 20 mL/min, balance purge: 40 mL/min).

A representative TGA curve is displayed in Figure 5. The sample shows a weight loss of only 0.3 w-% up to a temperature of 200 °C, which is due to sublimation and decomposition. TGA demonstrates the anhydrous and non-solvated nature of polymorph B.

Example 5: Stability of lorlatinib Form B

Stress Condition A:

Form B was stored at ambient condition and the phase consistency analysed periodically using powder X-ray diffraction. No transformation to Form 7 or any other solid form was seen within 59 days.

Stress Condition B:

Form B was stored at 40 °C (drying oven) and the phase identity checked periodically with powder X-ray diffraction. Within 47 days no transformation to Form 7 or any other form was seen.

Stress Condition C:

Form B was stored at 98% RH (RT) and the phase identity checked periodically with powder X-ray diffraction. Within 55 days no transformation to Form 7 or any other form was seen. Stress Condition D:

An FTIR heating experiment was performed with a temperature-controlled diamond ATR (PIKE GaldiATR) crystal on a Bruker Vertex 70 FTIR spectrometer (Bruker Analytische Messtechnik GmbH, Germany). The spectra were recorded between 4000 and 400 cm^-1 at an instrument resolution of 2 cm^-1 (38 scans per spectrum). Heating experiments performed with lorlatinib Form B of the present invention revealed that Form B is stable upon heating in the temperature range of 25 to 180 °C.

Stress Condition E: A manual laboratory press (PW10, P/O Weber, D-Remshalden) equipped with force and displacement sensors (Hottinger Baldwin, D-Darmstadt) was used for producing tablets consisting of neat lorlatinib Form B, whereat a tabletting pressure of 4 kN was applied. According to powder X-ray diffraction, no phase transformation to Form 7 or any other form occured. Example 6: Immediate release film-coated tablets comprising lorlatinib Form B

Immediate release film-coated tablets were prepared in 25 mg, 50 mg and 100 mg strengths using a dry granulation manufacturing process prior to compression. Lorlatinib Form B was blended with some proportion of the excipients and the blend was dry granulated using a roller compactor. After milling the granules were blended with the remainder of the excipients and tablets were compressed. The compositions of the tablets are provided in Table 5:

*removed during processing; does not appear in final product

Table 5: Immediate release tablets comprising lorlatinib Form B

Example 7: Scale-up of lorlatinib Form B

Lorlatinib (45.9 g) was charged in a glass reactor and dissolved in 1,4-dioxane (305 mL) at 25 °C. Subsequently, «-heptane (250 mL) was slowly added to the solution. After complete «- heptane addition the mixture was seeded with lorlatinib dioxane solvate (50 mg, e.g. prepared according to one of the procedures described in example 3 herein) and further stirred for 1 hour at 25 °C followed by 3 hours at 0 °C. The obtained solid was collected by filtration, washed with «-heptane and dried under vacuum (10 mbar) at 100 °C for 17 hours to yield lorlatinib Form B (43.5 g). Comparative Example 1: Solubility of Form B and Form 7

The solubility of the two polymorphs, Form 7 of WO 2017/021823 A1 and Form B of the present invention, was estimated in a 1 :3 (v/v) «-heptane / toluene mixture using the Crystal 16 parallel-reactor system. A heating rate of 0.3 K/min was applied. In the entire investigated temperature range of 15-87 °C Form B shows on average a solubility which is 60% higher than that of Form 7. Due to the fact that the solubility ratio of two polymorphs is independent of the solvent, a solvent mixture in which approx. 4 to 20 mg of lorlatinib dissolve in 1 mL has been chosen for the experiments. The corresponding solubility curves are displayed in Figure 8.

Comparative Example 2: Solubility of Form B and Form 7 in biorelevant medium The solubility of the two polymorphs, Form 7 of WO 2017/021823 A1 and Form B of the present invention, was determined in Fessif medium pH 5.0 at 37 °C. In the entire investigated time range Form B shows on average a solubility which is 60% higher than that of Form 7. The corresponding solubility curves are displayed in Figure 9. Comparative Example 3: Water wettability of Form B and Form 7

Drop shape analysis (DSA) gives information about the wetting behaviour of a compound. The shadow images of the sessile water drops were captured by a Kruess DSA25E instrument {Kruess, D-Hamburg, Germany ), equipped with illumination, a manual lift table (z-axis) and a video camera. The software Kruess Advance 1.6.2 was used for measuring the contact angle. The results are displayed in Table 6 below:

Table 6: Comparision of contact angles (wettability)

A smaller contact angle indicates higher wettability. Hence Form B shows better water wettability than Form 7.
