- lumen wall refers to a wall of a lumen, where the wall includes all layers from an inner perimeter to an outer perimeter of the lumen, such as, with respect to lumens in a body, the mucosa, submucosa, muscularis, serosa, and an outer wall of the lumen, with the constituent blood vessels and tissues.
- gastrointestinal tract refers herein to the intake/expulsion system of a body including, for example, the mouth, pharynx, esophagus, stomach, pylorus, small intestine, cecum, large intestine, colon, rectum, anus, and valves or sphincters therebetween.
- degrading or a grammatical variation thereof (e.g., “degrading”, “degraded”, “degradable”, and “degradation”) refers herein to weakening, partially degrading, or fully degrading, such as by dissolution, chemical degradation (including biodegradation), decomposition, chemical modification, mechanical degradation, or disintegration, which encompasses also, without limitation, dissolving, crumbling, deforming, shriveling, or shrinking.
- non-degradable refers to an expectation that degradation will be minimal, or within a certain acceptable design percentage, for at least an expected duration in an expected environment.
- FSH composition follicle stimulating hormone composition
- composition of FSH composition of FSH
- the FSH composition can include FSH either as the sole active agent or along with one or more additional active agents.
- ingestible dosage forms useful for delivering FSH to a subject in need thereof.
- the devices contain a payload formed from, or containing, a composition comprising FSH, and are structured to deliver the composition into a GI lumen wall of the subject or surrounding tissue thereof, e.g., a peritoneum or peritoneal cavity of the subject, after ingestion.
- the FSH provided in the devices may be any form of human FSH, including one or more of FSH isolated from human urine (human urinary-derived FSH) (e.g., REPRONEX®, MENOPUR®, and BRAVELLE®), and recombinant FSH, including recombinant human FSH expressed in mammalian cells, such as CHO cells (e.g., GONAL-F® (follitropin alfa) and FOLLISTIM® (follitropin beta)) or expressed in a human cell line such as the Per.C6 cell line (REKOVELLE® (follitropin delta).

- the device may contain a mechanism to effectuate delivery of the payload into a location of the GI tract, such as the intestinal wall or into and through an intestinal wall into, e.g., a peritoneum or peritoneal cavity of the subject.
- the mechanism includes an actuator that is triggered when the device is at a target delivery site, such as within the intestine.
- the mechanism may effectuate delivery of the pay load at another location in the GI tract, such as the stomach, large intestine, or colon.
- a portion of the valve When exposed to fluid such as intestinal fluid (e.g., after the capsule degrades), a portion of the valve degrades and allows the two reactants to mix, which results in formation of a gas (e.g., carbon dioxide or other innocuous gas) that expands the balloon.
- a gas e.g., carbon dioxide or other innocuous gas
- Inflation of the balloon aligns the Microsyringe substantially perpendicular to the long axis of the intestine and builds pressure in the balloon sufficient to provide the force needed to eject the Microneedle from the Microsyringe and inject the Microneedle into the intestinal wall or surrounding tissue thereof.
- the balloon deflates and the balloon and other components are excreted out through the GI tract with normal bowel movements.
- the shell is approximately needle-shaped. Degradation of the payload may occur within 1, 2, 3, 4, or 5 minutes of injection into the intestinal wall, or may take longer. Properties of the payload (e.g., structure and/or material) may be selected to delay release of the FSH from the payload.
- the device may include a detectable marker, such as a radiolabel, to assist in tracking the device as it proceeds through the subject’s GI tract.
- a detectable marker such as a radiolabel
- markers include, but are not limited to, barium sulfate (whose dispersion indicates fluid ingress inside the device and imminent delivery of the payload) and bismuth, which optionally may be included on or in a component contained in the device to radiographically track the component’s transit along the GI tract as well as to confirm its excretion.
- a balloon is selfsizing.
- the balloon is referred to herein as an “expandable component”. Such embodiments are described in more detail in the following paragraphs.
- the expandable component includes multiple sections. In the expanded configuration of the expandable component, at least one of the sections is non-compliant and at least one of the sections is compliant. Compliant refers to a state in which the section may be readily deformed, and non-compliant refers to a state in which the section resists deformation.
- each section will expand to a fully-extended state and the expandable component will reach its maximum dimensions, which may depend, for example, on materials used to form the expandable component and/or a capacity of an expansion module that is implemented (e.g., for expansion by inflation, maximum dimensions may be influenced by a limitation on an inflation force available from the expansion module, or by a stretch factor of a material or materials of the expandable component).
- the expansion module is part of a mechanism to effectuate delivery of the payload into the intestinal wall.
- This bending is due to the smaller dimension(s) of the hinge as compared to the corresponding dimension(s) of the non-compliant section(s), which in the expanded configuration of the expandable component leads to lower rigidity of the hinge as compared to rigidity of the non-compliant section(s).
- FIG. 2C illustrates that, subsequent to (or concurrent with) capsule shell 1010 degrading, expandable component 1000 begins to unfurl from its folded and/or rolled arrangement.
- the composition comprises about 3% w/w FSH, about 7% w/w phosphate salts, about 45% D-mannitol, about 5% PEG-3550, and about 40% L-methionine.
- such a composition is used to provide a dose of 450 IU FSH (follitropin alfa).
- FSH follitropin alfa
- compositions can be formulated to provided other doses as described herein in about the same volume/mass, such as by adjusting the FSH concentration (higher or lower), and adjusting the concentrations of the excipients accordingly.
- combination variations of these approaches e.g., adjustment of amount, adjustment of concentration
- the payload of the ingestible device contains a dose of FSH of about 150 IU or about 450 IU, e.g., a dose of FSH (follitropin alfa) of about 150 IU or about 450 IU or a dose of FSH (follitropin beta) of about 150 IU or about 450 IU, or a dose effective to achieve comparable FSH plasma levels with twice daily administration, or a dose effective to achieve comparable FSH plasma levels with twice daily administration and one missed dose.
- FSH follitropin alfa
- FSH follitropin beta
- the present disclosure also provides methods of treating one or more conditions such as infertility in female and male subjects, such as for stimulating follicle development or stimulating ovulation induction in a female patient or treating hypogonadotropic hypogonadism or idiopathic infertility in a male patient (e.g., for stimulation of spermatogenesis), and other conditions for which treatment with FSH may be indicated.
- Such methods may comprise administering by ingestion to a subject in need thereof an ingestible device as described herein.
- Microtablets of FSH were manufactured as follows, targeting a dose of 150 IU FSH (follitropin alfa) or 450 IU FSH (follitropin alfa) per microtablet.
- FSH stability in the microtablets was assessed after 1, 2, and 4 weeks storage at 2-8 °C, and met acceptance criteria (FSH content 80-120% of label claim; oxidation level ⁇ 10%).
- SC subcutaneous injection of Gonal-F (follitropin alfa) (600 lU/mL) at a dose of 20 lU/kg •
- Oral oral administration of one ingestible device (capsule) containing a 150 IU or 450 IU FSH (follitropin alfa) microtablet prepared as described in Example 1.
- Radiographic imaging was used to monitor capsule transit and confirm deployment within the small intestine.
- blood levels of FSH were assessed pre-dose, and at 2, 4, 6, 8, 10, 12, 24, 48, 72, 96, and 120 hours post-deployment.
- blood levels of FSH were assessed pre-dose and at 2, 4, 8, 12, 24, 48, 72, 96, and 120 hours post-deployment. Results are reported in FIG. 6 and in the table below (mean ⁇ SEM).
- the results indicate that FSH dosing of 75 IU twice daily (BID) is comparable to 150 IU once daily (FIG. 7), and that after one missed BID dose FSH plasma levels may fall below once daily levels (FIG. 8).
- the results also show that FSH dosing of 100 IU twice daily (BID) with one missed dose maintains FSH plasma levels at or above levels provided by 150 IU once daily (FIG. 9).
- a dose for twice daily administration could be determined that would maintain FSH plasma concentration at a target level even with a missed dose (e.g., as shown for 100 IU BID relative to 150 IU once daily).
- the ingestible devices as described herein are particularly advantageous in that regard, because a device can be loaded with any desired dose.
