Chiasma Provides Corporate Update and Previews Expected 2021 Milestones

MYCAPSSA® launch in US continuing to gain traction with physicians, patients, and payers

MYCAPSSA® EMA submission for EU marketing approval on track for mid-2021 following positive results of MPOWERED Phase 3 clinical trial

Needham, MA – January 6, 2021 – Chiasma, Inc. (NASDAQ: CHMA), a commercial-stage biopharmaceutical company utilizing its delivery platform technology to develop and commercialize oral therapies to improve the lives of patients with rare diseases currently treated with burdensome and painful injections, as evidenced by its recent phased launch of MYCAPSSA® as the first oral therapy for the treatment of acromegaly, today reviewed its 2020 accomplishments and previewed its anticipated 2021 corporate milestones.

2020 Key Highlights:

 

   

MYCAPSSA Approved in the U.S. as the first and only oral somatostatin analog (SSA) for the long-term maintenance treatment of patients with acromegaly who responded to and tolerated treatment with octreotide or lanreotide.

 

   

Approval was based on the positive CHIASMA OPTIMAL Phase 3 trial results which were published in the Journal of Clinical Endocrinology & Metabolism and presented at the 2020 Endocrine Society Annual Meeting (ENDO) along with six other scientific posters relevant to MYCAPSSA.

 

   

Commercial Launch of MYCAPSSA in the U.S. Late in the third quarter of 2020, Chiasma commenced the initial phase of the MYCAPSSA U.S. commercial launch with a focused salesforce calling on approximately one-third of key prescribing accounts. Chiasma progressed to the second phase of the launch at the beginning of 2021 with an expanded salesforce hired during the fourth quarter of 2020. Progression to the final phase of the launch with a full-strength salesforce is expected after market conditions improve beyond the COVID era.

 

   

Early launch insights and progress:

 

   

Coverage of MYCAPSSA by multiple payers insuring approximately 150 million lives provides a solid foundation for MYCAPSSA uptake in 2021.

 

   

Positive and encouraging feedback on MYCAPSSA from endocrinologists and patients supports the company’s goal of ultimately becoming the standard of pharmacological care in acromegaly.

 

   

Preliminary (unaudited) net revenues for 2020 are expected to be between $0.9 and $1.1 million.

 

   

Reported Positive Data from CHIASMA OPTIMAL Open Label Extension. The efficacy and safety (tolerability) seen in the 1-year extension phase of the study (48 weeks) was similar to that seen in the 36-week core study period. The mean of the insulin-like growth factor 1 (IGF-1) levels for the population of all MYCAPSSA treated patients that completed the 36-week core CHIASMA OPTIMAL trial and continued into the open-label extension (OLE) (n=19) was maintained within normal limits at the end of the 48-week OLE period.


LOGO

 

   

Reported Positive MPOWERED Phase 3 Topline Data. The MPOWERED study met its primary non-inferiority endpoint. 91% of patients on MYCAPSSA maintained IGF-1 response (95% CI = 80%, 97%) compared to 100% on injectable SSAs (95% CI = 91%, 100%). The positive clinical trial results provide Chiasma a pathway to pursue regulatory approval of MYCAPSSA in the European Union (EU), further strengthen the available robust clinical data set for MYCAPSSA and provide additional meaningful information for healthcare providers in treating patients with acromegaly.

 

   

Strengthened Balance Sheet for U.S. Commercial Launch. In April, Chiasma entered into a revenue interest financing agreement with HealthCare Royalty Partners (HCR) for up to $75 million. Also, in July, Chiasma raised approximately $75 million of net proceeds through an underwritten public offering of common stock and pre-funded warrants. Chiasma ended the year with approximately $135 million in cash, cash equivalents and marketable securities (exclusive of approximately $20 million of restricted cash), which is expected to fund its operations as currently planned through at least the end of 2021, including the execution of Chiasma’s planned 2021 U.S. MYCAPSSA commercial launch strategy.

“2020 was the beginning of an important transformation for Chiasma from a company with a strong research and development foundation to a commercial-stage company,” stated Raj Kannan, chief executive officer. “We are pleased with the progress of the MYCAPSSA launch to date and the encouraging feedback we have received from physicians, patients and payers. In 2021, we continue to build upon the MYCAPSSA launch in the United States while pursuing MYCAPSSA approval in the European Union. The recently reported positive MPOWERED clinical trial results further support our goal to make MYCAPSSA the new standard of pharmacological care in the long-term maintenance treatment of people with acromegaly.”

Anticipated 2021 Milestones and Related Guidance:

 

   

Grow MYCAPSSA revenues in the U.S. by building on the progress made with the initial, focused selling effort in the first four months since launch: Chiasma plans to drive adoption for MYCAPSSA with a broader group of physicians by expanding from a 36-person customer-facing team today to an approximately 45-person customer-facing team as market challenges associated with COVID-19 recede and payer coverage continues to expand.

 

   

MYCAPSSA EMA Submission. In mid-2021, Chiasma plans to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) seeking regulatory approval to market MYCAPSSA to patients with acromegaly in the EU.

 

   

CHIASMA OPTIMAL Open Label Extension Data Oral Presentation at Virtual ENDO 2021. Chiasma plans to present data on longer-term efficacy and safety of MYCAPSSA from the CHIASMA OPTIMAL trial’s open-label extension at the virtual 2021 Endocrine Society Annual Meeting (ENDO), which is being held March 20-23.


LOGO

 

   

Presentation of MPOWERED Phase 3 Data at Medical Conferences and Publication in a Peer Reviewed Medical Journal. Chiasma expects to present MPOWERED Phase 3 data analyses at upcoming endocrinology scientific meetings in spring and in fall 2021 and submit the results of the MPOWERED trial to a peer-reviewed journal for expected publication in 2021.

 

   

2021 Financial Guidance. Operating expense for the full year 2021 is expected to be in a range of $80 million to $90 million, including estimated stock-based compensation expense in a range of $5 million to $6 million. This guidance is based on the company’s current U.S. commercial plans and excludes expenditure for potential EU launch preparations of MYCAPSSA and potential additional new product development programs.

2021 LifeSci Advisors Corporate Access Event

Chiasma management will be available to meet with institutional investors and analysts virtually at the 2021 LifeSci Advisors Corporate Access Event on January 7-8 and 11-14.

About Acromegaly

Acromegaly typically develops when a benign tumor of the pituitary gland produces too much growth hormone, ultimately leading to significant health problems. Common features of acromegaly are facial changes, intense headaches, joint pain, impaired vision and enlargement of the hands, feet, tongue and internal organs. Serious health conditions associated with the progression of acromegaly include type 2 diabetes, hypertension, respiratory disorders and cardiac and cerebrovascular disease. Chiasma estimates that approximately 8,000 adult acromegaly patients are chronically treated with somatostatin analog injections in the United States.

OUR SCIENCE TPE technology and MYCAPSSA clinical trials


Slide 16

Capsules with TPE technology have an enteric coating to protect against degradation in the stomach. Once in the small intestine, the capsule is designed to dissolve and release the TPE formulation. TPE technology induces the reversible expansion of tight junctions between intestinal epithelial cells, a natural process to absorb nutrients.  Capsules containing TPE can allow drug therapies to enter systemic circulation while excluding toxins, bacteria and viruses. Validated TPE Delivery Technology Platform TPE enhances oral bioavailability, allowing for the development of oral formulations of injectable-only therapies

The mean of the IGF-1 levels for the population of all MYCAPSSA treated patients that completed the 36-week, double-blind placebo controlled (DPC) CHIASMA OPTIMAL trial and continued into the OLE (n=19) were maintained within normal limits at the end of the 48-week OLE period.  90% of patients enrolled into the OLE who were treated with MYCAPSSA during the DPC phase of the study (n=20) completed the 48-week OLE period. All patients who enrolled into the OLE as responders to MYCAPSSA (IGF-1 within normal limits, n=14) completed the 48-week OLE period and 93% maintained their response within the normal limits at the end of this period. The safety profile observed during OLE was generally consistent with the safety of MYCAPSSA noted in the 36-week CHIASMA OPTIMAL trial with no new patterns noted with the increased duration of exposure.

MYCAPSSA Non-inferior to Long-acting Injectable SSAs Achieved the pre-specified non-inferiority margin of -20% Primary Endpoint: IGF-1 Time Weighted Average (TWA)1 throughout the RCT phase < 1.3 x ULN 1 TWA response represents an integrated measure of efficacy across time. It is derived as the area under the curve (AUC) divided by the total amount of time under observation between the first and last IGF-1 values.
