Dear Stockholders

“Pivotal” is the only word to describe 2006. During the past year, we embarked on the final phase of our journey to become a fully 
integrated biopharmaceutical company. We launched the remaining registration trials for our lead product, the Technosphere® Insulin 
System. We backfilled our pipeline by moving a second product – an oncology therapeutic – into clinical development. We commenced 
the expansion of our manufacturing facility in Danbury, Connecticut in order to meet our anticipated commercial production needs 
for Technosphere® Insulin. We grew our workforce to 545 employees, bringing on board a number of experienced pharmaceutical 
professionals. We also raised net proceeds of $497 million in simultaneous debt and equity offerings, giving us the financial resources 
to move forward with our aggressive plans. 

Among the many highlights of 2006:

(cid:127) We completed the first Phase 3 trial of our lead product, Technosphere® Insulin. In this study of patients with type 2 diabetes, 
we demonstrated that our investigational product produced HbA1c improvements comparable to those seen in a group of patients 
treated with a rapid-acting insulin analog (RAA) but with substantially less mild/moderate hypoglycemia 
and no severe hyperglycemia. Strikingly, Technosphere® Insulin was associated with a significant weight 
reduction compared to the weight gain observed in the RAA group. 

(cid:127) We also observed that Technosphere® Insulin produced similar HbA1c and weight results in a Phase 
2 study of patients with type 1 diabetes. In this study, we observed weight loss as well as substantially 
reduced glucose fluctuations with Technosphere® Insulin following a meal – a finding that has important 
implications for the ability of our therapy to reduce long-term complications of diabetes. 

(cid:127) We completed enrollment of a two-year, pivotal, Phase 3 safety study of Technosphere® Insulin. We 
closed the enrollment of Study 030 in early September 2006 with 2051 patients. With study completion 
now targeted for September 2008, we remain on track to file a new drug application for Technosphere® 
Insulin by the end of 2008. 

(cid:127) We  initiated  the  remaining  pivotal  Phase  3  efficacy  studies  of  Technosphere®  Insulin.  Studies 
009 and 102 are now enrolling patients at centers in the United States, Europe and Latin America. An 
additional Phase 3 efficacy study, 103, is also enrolling patients.

(cid:127) We received clearance from the FDA of our investigational new drug application for MKC1106-PP, allowing us to begin enrolling 
patients in a Phase 1 trial to evaluate this product for the treatment of a variety of cancers, including breast, lung, ovarian, pancreatic, 
renal and colorectal cancers and melanoma. 

While we build upon these accomplishments, we realize that our ambition level exceeds our current resources and capabilities. 
Although  we  are  confident  that  Technosphere®  Insulin,  once  approved,  will  be  a  highly  successful  product,  we  realize  that  our 
strength lies in discovery, development and manufacturing. We do not yet possess the sales and marketing capability required to 
launch Technosphere® Insulin in the United States to large numbers of general practitioners as well as specialists, nor do we have 
the resources to commercialize in Europe and elsewhere. For this reason, we continue to hold discussions with potential sales and 
marketing  partners  who  can  provide  this  expertise  and  can  help  to  accelerate  the  penetration  of  Technosphere®  Insulin  into  the 
diabetes market. We have a strong belief in the value of our lead product and we want to make sure that we do the right deal with the 
right partner. We can afford to be patient. 

That we can afford to be patient is because our stockholders have been tremendously supportive. Our simultaneous offerings of 
debt and equity last fall were both oversubscribed and included many high-quality institutions. We sincerely appreciate this vote of 
confidence in our product and our business plans and are working hard to ensure that your trust in us is justified. 

The year ahead will be extraordinarily busy for us as we conduct our pivotal trials and advance our level of commercial readiness. 
There may be few external signs of progress – we will not be in a position to report on our pivotal trials until 2008 – but we will be highly 
engaged nonetheless. 

Sincerely,

Diabetes 

from a patient’s perspective

Diabetes  is  a  chronic  condition  resulting  from  the  insuffi cient  production  of,  or 

lack  of  response  to,  insulin,  a  key  regulator  hormone  of  the  body’s  metabolism. 

In  a  healthy  body,  the  rise  in  blood  glucose  levels  after  a  meal  signals  cells  in  the 

pancreas—beta  cells—to  secrete  insulin  into  the  bloodstream.  Insulin,  in  turn, 

enables  glucose  to  enter  cells  in  the  body  where  it  is  burned  for  energy  or  stored 

for  future  use.  People  with  diabetes  either  do  not  produce  enough  insulin  or  become 

resistant  to  their  own  insulin.  As  a  result,  glucose  builds  up  in  the  bloodstream. 

2  MANNKIND | 2006 ANNUAL REPORT

Over time, diabetes can lead to a myriad 
of  life-threatening  complications,  including 
heart  disease,  stroke,  vision  loss,  kidney 
disease  and  neuropathy  (nerve  damage). 
Ultimately, if untreated, the disease can lead 
to coma and death.

There  are  two  forms  of  the  disease. 
Type  1  diabetes  is  an  autoimmune  disease 
characterized  by  a  complete  lack  of  insulin 
secretion by the pancreas. People with type 1 
diabetes require insulin injections in order to 
live. Their bodies produce little or no insulin 
because  their  immune  systems  attack  and 
destroy  the  insulin-producing  beta  cells  in 
the pancreas.

In  type  2  diabetes,  the  pancreas 
continues  to  produce  some  insulin;  but 
insulin  dependent  cells  become  resistant 
toward  the  insulin  effect.  Over  time,  the 
pancreas  becomes 
increasingly  unable 
to  secrete  adequate  amounts  of  insulin  to 
support metabolism. 

Type 2 diabetes is the more prevalent form 
of  the  disease,  affecting  approximately  90% 
to 95% of people diagnosed with diabetes.

CURRENT TREATMENT

The  goal  of  diabetes  treatment  is  to 
achieve  and  maintain  blood  glucose  levels 
within  or  near  the  normal  range  (90  to  126 
mg/dL). Maintaining blood glucose levels in 
this range can be very difficult with current 
therapies.  In  order  to  effectively  manage 
their condition, diabetes patients must learn 
to  prevent  their  blood  glucose  levels  from 
plunging too low (hypoglycemia) or spiking 
too high (hyperglycemia). 

Day-to-day  maintenance 

for  type  1 
diabetes  requires  a  strict  daily  treatment 
regimen of multiple insulin injections together 
with diet, exercise and blood glucose testing 
(sometimes many times per day). 

Unlike  type  1  diabetes,  type  2  diabetes 
disease  management,  at  least  early  in  the 
disease,  is  more  dependent  on  lifestyle 
choices 
including  healthful  eating  and 
exercise,  together  with  daily  blood  glucose 
testing.  Significant  changes  in  diet  and 
exercise can temporarily enable patients with 
early  type  2  diabetes  to  eliminate  the  need 
for  medications.  However,  type  2  diabetes 
is  a  progressive  disease.  In  many  cases, 

patients  with  type  2  diabetes  eventually 
require medical treatment.

is  the  standard  of  care  for  patients  with 
diabetes, its use has certain shortcomings.

ANTI-DIABETIC MEDICATIONS ■

INSULIN CHALLENGES ■

There  are  several  non-insulin  diabetes 
treatments that can be used to control blood 
glucose levels, either alone or in combination 
with insulin. 

families 

Today  these  drugs  can  be  divided 
including 
into  seven  distinct 
(e.g.  Glucotrol®,  Diabeta®, 
sulfonylureas 
Glynase®,  Micronase® 
and  Amaryl®), 
meglitinides  (e.g.  Prandin®  and  Starlix®), 
biguanides (e.g. Glucophage®,  Glucophage® 

The primary challenge for insulin therapy 
involves  synchronizing  the  onset  of  insulin 
activity  with  the  absorption  of  mealtime 
glucose. In healthy individuals, blood insulin 
levels  rise,  and  glucose  production  by  the 
liver  stops,  within  minutes  after  glucose 
from a meal enters the blood. These events 
allow healthy individuals to maintain normal 
glucose levels and avoid high blood glucose 
levels for prolonged periods after eating.

XR and Fortamet®), thiazolidinediones (e.g. 
Avandia®  and  Actos®),  alpha-glucosidase 
inhibitors  (e.g.  Prandase®,  Precose®  and 
Glyset®),  incretin  mimetics  (e.g.  Byetta®), 
and  inhibitors  of  dipeptidyl  peptidase  IV 
(e.g. Januvia®). 

The  large  number  of  such  drugs  is 
an  indicator  of  just  how  critical  diabetes 
treatment  has  become.  However,  most 
treatments  have  significant  side  effects 
and are not considered ideal for one reason 
or  another.  Insulin  replacement  continues 
to  play  a  significant  role  in  the  treatment 
of diabetes.

INSULIN ■

All  individuals  with  type  1  diabetes 
must  use  insulin  to  control  their  blood 
glucose  levels,  and  roughly  30%  of  those 
with  type  2  diabetes  also  require  insulin. 
injections 
Until  recently,  subcutaneous 
were  the  only  way  to  administer  insulin. 
Many  different  insulins  are  available  for 
diabetes  treatment.  These  insulins  are 
classified  by  the  speed  with  which  they 
lower  blood  glucose  and  the  duration  of 
glucose-lowering  activity.  While  insulin 

However,  for  patients  with  diabetes, 
injected mealtime insulin enters the system 
slowly, requiring up to three hours to reach 
peak  activity.  During  this  time,  the  patient 
may  experience  hyperglycemia  until  the 
injected  insulin  takes  effect  and  lowers 
blood glucose. Typically, the insulin outlasts 
the  glucose  ingested  from  a  meal,  which 
then  leads  to  hypoglycemia.  This  cycle  of 
extremes  in  blood  glucose  levels  eventually 
causes long-term organ damage.

This  dilemma  led  to  the  development 
of  rapid-acting  insulin  analogs  that  start 
working  15  to  30  minutes  after  injection 
and  reach  peak  effectiveness  in  30  to  90 
minutes;  however,  their  action  can  persist 
for  up  to  5  hours.  Rapid-acting  analogs  are 
an  improvement  over  regular  insulin,  but 
the  need  remains  for  a  new  form  of  insulin 
that takes effect even more rapidly and has 
a  duration  of  action  that  does  not  exceed 
the period of glucose ingestion from a meal. 
An  insulin  therapy  that  mimics  the  body’s 
natural insulin response would be ideal. We 
believe  that  Technosphere®  Insulin  has  the 
potential to be that ideal insulin.

The  red  line  illustrates  the  elevated  fasting  glucose  and  large  glucose

basal  insulin  lowers  fasting  glucose  and  reduces  acute  glucose  fluctuations.
The  black  line  shows  how  the  addition  of  mealtime  insulin  to  basal  insulin 
causes a reduction in acute glucose fluctuations.

Recent fi ndings have indicated 

that diabetes therapy must strive 

to manage acute glucose fl uctuations 

in addition to average glucose levels 

(see Illustration 4.a). The potential 

value of MannKind’s Technosphere® 

Insulin System can be seen in how 

effectively it controls the extent of 

acute glucose fl uctuations.

4  MANNKIND | 2006 ANNUAL REPORT

 
Patients with diabetes develop abnormally high levels of glucose, 
a  state  known  as  hyperglycemia,  either  because  they  produce 
insufficient levels of insulin or because they fail to respond adequately 
to the insulin produced by the body. Over time, high levels of blood 
glucose  can  lead  to  major  complications,  including  high  blood 
pressure, blindness, amputation, kidney failure, heart attack, stroke 
and death.

HBA1C LEVELS ■

There  are  two  components  to  the  hyperglycemia  concern. 
The  first  is  related  to  the  duration  and  magnitude  of  the  chronic 
sustained hyperglycemia associated with poorly controlled diabetes. 
This component is assessed by measuring the level of glycosylated 
hemoglobin  (HbA1c),  which  is  a  reflection  of  the  average  glucose 
levels  in  the  bloodstream  over  the  preceding  three  or  four  months. 
HbA1c levels are an indication of the general degree of glucose control. 
As can be seen in Illustration 4.a, the baseline or fasting glucose levels 
can be a major factor in average glucose levels. An important goal of 
all diabetes therapies is to lower HbA1c levels. 

ACUTE GLUCOSE FLUCTUATIONS ■

The second component of hyperglycemia relates to the extent of 
acute  fluctuations  primarily  in  blood  glucose  above  and  below  the 
average  level.  These  fluctuations  occur  in  response  to  meals.  Over 
time,  excessive  glucose  fluctuations  damage  blood  vessels  and 
surrounding cells. This damage shows up first in the fine capillaries 
found in the eyes, kidneys, fingers and toes. This damage can lead to 
blindness, kidney failure, amputation, heart attack and stroke. 

DCCT/EDIC TRIAL ■

There is growing evidence that doctors and patients should place 
greater  emphasis  on  managing  acute  glucose  fluctuations.  In  the 
Diabetes Control and Complications Trial (DCCT), a group of patients 
treated  using  conventional  insulin  therapy  (1  to  2  insulin  injections 
per day along with daily urine glucose tests) was compared to a group 
treated using intensive insulin therapy (either an insulin pump or at 

least 3 insulin injections and at least 4 blood glucose tests per day). 
In total, 1,441 patients were followed for an average of 6.5 years each. 
The  researchers  found  that  intensive  insulin  therapy  produced 
a  significant  reduction  in  HbA1c  levels  compared  to  conventional 
insulin therapy; the difference between treatment groups remained 
evident  for  the  duration  of  the  study.  Moreover,  the  patients  who 
had  been  intensively  treated  also  showed  significant  decreases 
in  risk  for  kidney  and  eye  damage  compared  to  the  conventional 
treatment  group.  When  these  results  were  reported,  the  DCCT 
was discontinued. 

A group of 1,375 of these subjects (half from each of the original 
treatment  groups)  was  subsequently  followed  in  the  Epidemiology 
of  Diabetes  Interventions  and  Complications  (EDIC)  study.  After 
seven  years  in  the  EDIC  study,  the  HbA1c  levels  of  the  former 
conventional  therapy  group  did  not  differ  from  the  HbA1c  levels  of 
the former intensive treatment group – the HbA1c levels of the former 
conventional therapy group had improved from the DCCT while those 
of the former intensive therapy group had deteriorated.

However,  the  former  conventional  therapy  group  continued  to 
show  an  elevated  risk  of  kidney  and  eye  damage  compared  to  the 
former  intensive  therapy  group.  The  implication  of  these  results 
is  that  intensive  insulin  therapy  —  which  reduces  acute  glucose 
fluctuations  —  can  be  beneficial  for  patients  with  diabetes,  even 
years after the therapy has been less intensified. However, the EDIC 
also demonstrates how intensive insulin therapy is difficult for many 
patients  to  implement  in  a  home  setting.  Moreover,  with  intensive 
therapy,  the  insulin  products  on  the  market  today  do  not  enter  the 
bloodstream  fast  enough  to  replicate  the  tight  coupling  between 
changes  in  blood  glucose  levels  and  the  release  of  insulin  by  the 
pancreas that is seen in healthy individuals without diabetes. 

MannKind’s  Technosphere® 

Insulin  therapy  addresses  this 

problem in two ways:
(cid:127)  Insulin  administration  by  inhalation  is  more  convenient  than 

injection and also more amenable to intensive therapy.

(cid:127)  The Technosphere® Insulin formulation delivers insulin monomers 
to the deep lung. The insulin is absorbed rapidly and begins to lower 
blood glucose faster than injected insulin, mimicking insulin action 
in healthy individuals.

MANNKIND | 2006 ANNUAL REPORT  5 

HOW DOES THE 
TECHNOSPHERE® 
INSULIN DELIVERY 
SYSTEM WORK?

REPLICATES NATURAL PROCESS ■

In clinical trials to date, our Technosphere® Insulin System has produced 
a profile of insulin levels in the bloodstream that approximates the post-meal 
insulin profiles normally seen in healthy individuals. 

Technosphere®  Insulin  has  been  shown  to  be  rapidly  absorbed  into 
the  bloodstream  following  inhalation,  reaching  peak  levels  within  12  to 
14  minutes.  As  a  result  of  this  rapid  onset  of  action,  most  of  the  glucose-
lowering  activity  of  Technosphere®  Insulin  occurs  within  the  first  three 
hours  of  administration  —  which  is  generally  the  period 
during  which  glucose  becomes  available  from  a 
meal — instead of the much longer duration of 
action  observed  when  insulin  is  injected 
subcutaneously. 

We  believe  that  the  relatively 

short  duration  of  action  of 
Technosphere®  Insulin  reduces 
the  need  for  patients  to  snack 
between  meals  in  order  to 
manage ongoing blood glucose 
excursions (rapid glucose level 
elevations  and  depressions). 
Indeed,  in  our  clinical  trials, 
we have observed that patients 
the  Technosphere® 
using 
Insulin  System  have  achieved 
significant  reductions  in  acute 
glucose fluctuations and significant 
decreases  in  HbA1c  levels  without 
the  weight  gain  typically  associated 
with insulin therapy.

FORMULATION TECHNOLOGY ■

Technosphere® Insulin’s rapid action may be related 
to  unique  characteristics  of  both  our  carrier  molecule 
and the insulin in our formulation.

Our 

Technosphere® 

formulation 
technology  is  centered  on  a  class  of 
pH-sensitive  organic  molecules 
that 
self-assemble  into  small  particles  under 
mildly  acidic  conditions.  Certain  drugs, 
such as insulin, can be loaded onto these 
particles  by  combining  a  mildly  acidic 
solution of the drug with a suspension of 
Technosphere®  material,  which  is  dried 
to  a  powder.  This  powder  is  then  filled 
into plastic cartridges and packaged. 

To administer Technosphere® Insulin, 
a  patient  loads  a  cartridge  into  our 
palm-sized  inhaler.  By  inhaling  through 
the  inhaler,  air  is  pulled  through  the 
cartridge, which aerosolizes the powder 
and pulls the particles into the air current 
and  out  through  the  mouthpiece.  The 
particles are small and have aerodynamic 
properties  that  enable  them  to  travel 
deep into the lungs. 

When  the  particles  contact  the 
moist  lung  surface  with  its  neutral  pH, 
the  Technosphere®  particles  dissolve 
immediately.  This  releases  the  insulin 
molecules,  which  then  diffuse  across  a

that  occurs  without  disruption  of

INSULIN MONOMERS ■

When  the  Technosphere®  particles 
dissolve, the insulin that is released is 
in  a  form  that  can  readily  be  used  by 
the body. 

In  most  pharmaceutical  dosage 
forms,  regular  human  insulin  exists 
as  a  hexamer,  a  complex  of  six 
associated insulin  molecules. In order 
to  exert  a  pharmacological  effect, 
the  hexamer  must  first  dissociate 
into 
three  dimers — complexes  of 
two  insulin  molecules — which  then 
further  dissociate 
individual 
insulin  molecules,  or  monomers.  Only 
these  monomers  exert  a  physiological 
effect. Rapid-acting insulin analogs are 
designed  to  be  fragile  hexamers  that 

into 

dissociate  more  quickly  than  regular 
insulin,  thereby  reducing  the  time 
required  to  achieve  an  effect,  but  this 
is  still  far  slower  than  insulin  that  is 
released from a healthy pancreas. 

The 

insulin 

released 

from 
is  already 
Technosphere®  particles 
largely 
in  monomeric  form.  During 
the  manufacture  of  Technosphere® 
Insulin, we cause hexameric insulin to 
dissociate into insulin monomers before 
being 
loaded  onto  Technosphere® 
particles.

These  properties  may  explain  why 
the  Technosphere® 
Insulin  System 
produces  such  a  rapid  elevation  in 
insulin levels following inhalation. This 
time-action  profile  approximates  the 
insulin profile normally seen in healthy 
individuals 
following 
immediately 
the  beginning  of  a  meal,  but  which 
is  absent  in  patients  with  diabetes.

Pulmonary  safety  was  assessed  by  different  measurements  of  lung

RESULTS ■

This  study  involved  110  patients  with  type  1  diabetes  on  basal/
prandial  therapy,  a  dosing  regimen  used  in  the  everyday  intensive 
management of diabetes. Patients were randomized into a group that 
used Technosphere® Insulin (n=54) at mealtime or a group that used the 
RAA (n=56) at mealtimes. Both groups used insulin glargine (Lantus®) 
as a basal insulin. 

The patients were followed for 12 weeks during which individual 
adjustments  of  therapy  were  made  as  necessary.  Standardized  meal 
tests  were  conducted  at  study  initiation  and  after  8  and  12  weeks 
of  therapy.  HbA1c  levels  and  post-meal  glucose  fluctuations  were 
assessed at the initial visit, at the start of randomized treatment and at 
study completion. Comparisons were made between the patient group 
receiving Technosphere® Insulin and the patient group receiving RAA. 

After  12  weeks  of  treatment,  both  patient  groups  achieved 
a  statistically  significant  decrease  in  HbA1c  levels  (0.83%  in  the 
Technosphere®  Insulin  patient  group  and  0.99%  in  the  RAA  patient 
group). However, during the standardized meal tests conducted at week 
12,  we  observed  a  rather  striking  difference  between  the  post-meal 
glucose levels of the two groups. Graph 9.a shows that, in the group that 
received the RAA, there was a sharp rise in blood glucose immediately 
after the meal, followed by a gradual decline, reaching baseline in about 
four hours. In the group that received Technosphere® Insulin, there was 
a  short  dip  in  blood  glucose  immediately  after  the  dose;  subsequent 
glucose fluctuations were considerably lower than with the RAA.

We were also intrigued by the observation 
that,  over  12  weeks  of  treatment,  the  RAA 
patient group experienced an average increase 
in weight of 1.8 lbs. whereas the Technosphere® 
Insulin patient group experienced an average 
weight  loss  of  2.0  lbs.  This  difference  in 
weight  change  between  the  two  groups  was 
statistically significant (p=0.0018). 

After  12  weeks  of  treatment,  pulmonary 
function, as measured by FEV1, and DLco, did 
not differ from baseline for the Technosphere® 
Insulin  and  RAA  patient  groups.  The 
results  were  consistent  with  the  Company’s 
previous  studies  of  Technosphere®  Insulin 
that  have  demonstrated

Our  study  also  found  that  patients  using 
Technosphere® Insulin lost weight during the 
study  in  contrast  to  patients  using  the  RAA 
who  gained  weight.  Moreover,  after  twelve 
weeks  of  treatment,  pulmonary  function  did 
not differ between the two patient groups.

This  study  involved  308  patients  with 
type  2  diabetes.  Patients  were  randomized 
into a group that used Technosphere® Insulin 
(n=150) at mealtimes or a group that used the 
RAA (n=158) at mealtimes. Both groups used 
insulin glargine (Lantus®) as a basal insulin. 

Patients were followed for 24 weeks during 
which individual adjustments of therapy were 
made  as  necessary.  Glucose  control  in  both 
treatment  groups  was  assessed  by  periodic 
determinations  of  HbA1c  levels.  We  did  not 
conduct standardized meal tests in this study. 
Pulmonary  function  was  assessed  by  serial 
measurements of FEV1 and forced vital capacity 
(FVC), a measure of pulmonary capacity. After 
the treatment period, patients reverted to their 
conventional therapy and pulmonary function 
was followed for an additional 24 weeks.

RESULTS ■

Both patient groups achieved statistically 
significant  improvements  in  HbA1c  levels 
(1.05%  in  the  Technosphere®  Insulin  patient 
group  and  1.30%  in  the  RAA  patient  group). 
Pulmonary function, as assessed by FEV1 and 
FVC,  did  not  differ  between  the  two  patient 
groups after six months of treatment and after 
the six month withdrawal period. 

Yet  there  were 

important  differences 
between  the  treatment  groups.  Significantly 
fewer  patients  experienced  mild  to  moderate 
hypoglycemia  in  the  Technosphere®  Insulin 
patient group than in the RAA patient group 
and  there  were  no  severe  hypoglycemic 
incidences.  In  addition,  after  six  months  of 
treatment, the RAA patient group experienced 
an average weight increase of 0.5 lbs. whereas 
the  Technosphere® 
Insulin  patient  group 
experienced  a  weight  loss  of  1.7  lbs.  This 
difference in weight change between the two 
groups was statistically significant (p=0.0007). 

> See illustration 11.a – Weight Changes

Study  014  was  designed  to  compare  the 

safety and efficacy (blood glucose control) of 

Technosphere® Insulin and the insulin aspart 

(Novolog®),  a  rapid-acting  insulin  analog 

(RAA),  in  patients  with  type  2  diabetes.

CONCLUSION ■

As in study 101, patients using Technosphere® 
Insulin  achieved  comparable  decreases  in 
HbA1c  levels  as  patients  treated  with  an 
injected  RAA.  In  addition,  we  observed  no 
adverse effect on pulmonary function in either 
treatment group. However, unlike the injected 
RAA  group,  Technosphere®  Insulin  patients 
lost weight during the treatment period.

WHY NO WEIGHT GAIN? ■ 

We  were  surprised  to  observe  no  weight 

gain,  and  even  weight  loss,  in  patients  using 

the  Technosphere® 

Insulin  System 

to 

control  their  blood  glucose.  We  believe that 

this  phenomenon  may  stem 

from 

the 

synchronization  of  Technosphere® 

Insulin 

activity  to  meal  digestion.  Meal  digestion 

is  somewhat  variable,  but  generally 

lasts 

approximately  three  hours.  Graph  11.b, 

taken  from  our  clinical  data,  illustrates  that 

over  80%  of  the  glucose-lowering  activity  of 

regular  subcutaneous  insulin  is  not  exerted 

until  at  least  three  hours  after  a  meal.  At 

this  point,  patients  run  the  risk  of  becoming 

hypoglycemic.  Typically, 

this 

situation 

encourages  patients  to  eat  snacks  between 

meals,  contributing  to  the  weight  gain  often 

associated  with  insulin  therapy.  By  contrast, 

approximately  three-quarters  of  the  action  of 

Technosphere®  Insulin  occurs  within  the  first 

three hours after a meal. After this point, there 

is little insulin present to cause hypoglycemia, 

thereby alleviating the need to snack.

t is 
It is clear that the rising incidence of diabetes is creating a looming medical 

crisis that will demand more effective treatments. The therapies of the last 

80 years are not adequate to address the epidemic of diabetes. 

What is not obvious is that the large number of diabetes therapies in 

development do not address key issues critical to the management of the 

disease. With Technosphere® Insulin, MannKind is assuming a leadership role 

in insulin delivery with a product that represents the potential first offering 

in a new class of insulins—supra-rapid acting insulins that provide real-time 

control of glucose that mimics nature. 

The growing diabetes market will ultimately require multiple therapies. With 

Technosphere® Insulin, MannKind may bring clinicians a powerful new option 
ew option

in diabetes therapy.
